App-ops are used for two purposes: Access control and tracking.
App-ops cover a wide variety of functionality from helping with runtime permissions access control and tracking to battery consumption tracking.
Access control
App-ops can either be controlled for each uid or for each package. Which one is used depends on the API provider maintaining this app-op. For any security or privacy related app-op the provider needs to control the app-op for per uid as all security and privacy is based on uid in Android.
To control access the app-op can be set to a mode to:
[MODE_DEFAULT](/reference/android/app/AppOpsManager#MODE%5FDEFAULT)
Default behavior, might differ from app-op or app-op
[MODE_ALLOWED](/reference/android/app/AppOpsManager#MODE%5FALLOWED)
Allow the access
[MODE_IGNORED](/reference/android/app/AppOpsManager#MODE%5FIGNORED)
Don't allow the access, i.e. don't perform the requested action or return no or placeholder data
[MODE_ERRORED](/reference/android/app/AppOpsManager#MODE%5FERRORED)
Throw a [SecurityException](/reference/java/lang/SecurityException) on access. This can be suppressed by using a...noThrow method to check the mode
API providers need to check the mode returned by [noteOp(String, int, String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String%29) if they are are allowing access to operations gated by the app-op. [unsafeCheckOp(String, int, String)](/reference/android/app/AppOpsManager#unsafeCheckOp%28java.lang.String,%20int,%20java.lang.String%29) should be used to check the mode if no access is granted. E.g. this can be used for displaying app-op state in the UI or when checking the state before later calling [noteOp(String, int, String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String%29) anyway.
If an operation refers to a time span (e.g. a audio-recording session) the API provider should use [startOp(String, int, String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String%29) and [finishOp(String, int, String)](/reference/android/app/AppOpsManager#finishOp%28java.lang.String,%20int,%20java.lang.String%29) instead of [noteOp(String, int, String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String%29).
Runtime permissions and app-ops
Each platform defined runtime permission (beside background modifiers) has an associated app op which is used for tracking but also to allow for silent failures. I.e. if the runtime permission is denied the caller gets a [SecurityException](/reference/java/lang/SecurityException), but if the permission is granted and the app-op is [MODE_IGNORED](/reference/android/app/AppOpsManager#MODE%5FIGNORED) then the callers gets placeholder behavior, e.g. location callbacks would not happen.
App-op permissions
App-ops permissions are platform defined permissions that can be overridden. The security check for app-op permissions should by [default](/reference/android/app/AppOpsManager#MODE%5FDEFAULT) check the permission grant state. If the app-op state is set to [MODE_ALLOWED](/reference/android/app/AppOpsManager#MODE%5FALLOWED) or [MODE_IGNORED](/reference/android/app/AppOpsManager#MODE%5FIGNORED) the app-op state should be checked instead of the permission grant state.
This functionality allows to grant access by default to apps fulfilling the requirements for a certain permission level. Still the behavior can be overridden when needed.
Tracking
App-ops track many important events, including all accesses to runtime permission protected APIs. This is done by tracking when an app-op was [noted](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String%29) or[started](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String%29). The tracked data can only be read by system components.
Only [noteOp(String, int, String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String%29)/[startOp(String, int, String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String%29) are tracked; [unsafeCheckOp(String, int, String)](/reference/android/app/AppOpsManager#unsafeCheckOp%28java.lang.String,%20int,%20java.lang.String%29) is not tracked. Hence it is important to eventually call [noteOp(String, int, String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String%29) or [startOp(String, int, String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String%29) when providing access to protected operations or data.
Some apps are forwarding access to other apps. E.g. an app might get the location from the system's location provider and then send the location further to a 3rd app. In this case the app passing on the data needs to call [noteProxyOp(String, String)](/reference/android/app/AppOpsManager#noteProxyOp%28java.lang.String,%20java.lang.String%29) to signal the access proxying. This might also make sense inside of a single app if the access is forwarded between two parts of the tagged with different attribution tags.
An app can register an [OnOpNotedCallback](/reference/android/app/AppOpsManager.OnOpNotedCallback) to get informed about what accesses the system is tracking for it. As each runtime permission has an associated app-op this API is particularly useful for an app that want to find unexpected private data accesses.

Constants
MODE_ERRORED
public static final int MODE_ERRORED
Result from [checkOpNoThrow(String, int, String)](/reference/android/app/AppOpsManager#checkOpNoThrow%28java.lang.String,%20int,%20java.lang.String%29), [noteOpNoThrow(String, int, String)](/reference/android/app/AppOpsManager#noteOpNoThrow%28java.lang.String,%20int,%20java.lang.String%29), [startOpNoThrow(String, int, String)](/reference/android/app/AppOpsManager#startOpNoThrow%28java.lang.String,%20int,%20java.lang.String%29): the given caller is not allowed to perform the given operation, and this attempt should cause it to have a fatal error, typically a [SecurityException](/reference/java/lang/SecurityException).
Constant Value: 2 (0x00000002)
MODE_FOREGROUND
public static final int MODE_FOREGROUND
Special mode that means "allow only when app is in foreground." This is not returned from [unsafeCheckOp(String, int, String)](/reference/android/app/AppOpsManager#unsafeCheckOp%28java.lang.String,%20int,%20java.lang.String%29), [noteOp(String, int, String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String%29), [startOp(String, int, String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String%29). Rather,[unsafeCheckOp(String, int, String)](/reference/android/app/AppOpsManager#unsafeCheckOp%28java.lang.String,%20int,%20java.lang.String%29) will always return [MODE_ALLOWED](/reference/android/app/AppOpsManager#MODE%5FALLOWED) (because it is always possible for it to be ultimately allowed, depending on the app's background state), and [noteOp(String, int, String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String%29) and [startOp(String, int, String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String%29) will return [MODE_ALLOWED](/reference/android/app/AppOpsManager#MODE%5FALLOWED) when the app being checked is currently in the foreground, otherwise [MODE_IGNORED](/reference/android/app/AppOpsManager#MODE%5FIGNORED).
The only place you will this normally see this value is through[unsafeCheckOpRaw(String, int, String)](/reference/android/app/AppOpsManager#unsafeCheckOpRaw%28java.lang.String,%20int,%20java.lang.String%29), which returns the actual raw mode of the op. Note that because you can't know the current state of the app being checked (and it can change at any point), you can only treat the result here as an indication that it will vary between[MODE_ALLOWED](/reference/android/app/AppOpsManager#MODE%5FALLOWED) and [MODE_IGNORED](/reference/android/app/AppOpsManager#MODE%5FIGNORED) depending on changes in the background state of the app. You thus must always use [noteOp(String, int, String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String%29) or [startOp(String, int, String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String%29) to do the actual check for access to the op.

Public methods
checkOp
public int checkOp (String op, int uid, String packageName)
Check whether an application can perform an operation.
For platform versions before [Build.VERSION_CODES.BAKLAVA](/reference/android/os/Build.VERSION%5FCODES#BAKLAVA), this is_not_ a security check; you must use [noteOp(String,int,String,String,String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String,%20java.lang.String,%20java.lang.String%29) or [startOp(String,int,String,String,String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String,%20java.lang.String,%20java.lang.String%29) for your actual security checks. This function can just be used for a quick check to see if an operation has been disabled for the application, as an early reject of some work.
For platform versions equal to or after [Build.VERSION_CODES.BAKLAVA](/reference/android/os/Build.VERSION%5FCODES#BAKLAVA), it does the same security check as [noteOp(String,int,String,String,String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String,%20java.lang.String,%20java.lang.String%29) and[startOp(String,int,String,String,String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String,%20java.lang.String,%20java.lang.String%29), and should be preferred to use.
This API does not modify the time stamp or other data about the operation.
| Parameters | |
|---|---|
| op | String: The operation to check. One of the OPSTR_* constants. This value cannot be null. |
| uid | int: The uid of the application attempting to perform the operation. |
| packageName | String: The name of the application attempting to perform the operation. This value cannot be null. |
| Returns | |
|---|---|
| int | Returns MODE_ALLOWED if the operation is allowed, orMODE_IGNORED if it is not allowed and should be silently ignored (without causing the app to crash). |
| Throws | |
|---|---|
| SecurityException | If the app has been configured to crash on this op. |
checkOp
public int checkOp (String op, int uid, String packageName, String attributionTag)
Check whether an application can perform an operation.

| Parameters | |
|---|---|
| op | String: The operation to check. One of the OPSTR_* constants. This value cannot be null. |
| uid | int: The uid of the application attempting to perform the operation. |

| uid | int |
| packageName | String: This value cannot be null. |
| Returns |
|---|
| boolean |
noteOp
public int noteOp (String op, int uid, String packageName)
This method was deprecated in API level 30.
Use [noteOp(String,int,String,String,String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String,%20java.lang.String,%20java.lang.String%29) instead
| Parameters | |
|---|---|
| op | String: This value cannot be null. |
| uid | int |
| packageName | String: This value cannot be null. |
| Returns |
|---|
| int |
noteOp
public int noteOp (String op, int uid, String packageName, String attributionTag, String message)
Make note of an application performing an operation and check if the application is allowed to perform it.
If this is a check that is not preceding the protected operation, use[unsafeCheckOp(String, int, String)](/reference/android/app/AppOpsManager#unsafeCheckOp%28java.lang.String,%20int,%20java.lang.String%29) instead.
The identity of the package the app-op is noted for is specified by theuid and packageName parameters. If this is noted for a regular app both should be set and the package needs to be part of the uid. In the very rare case that an app-op is noted for an entity that does not have a package name, the package can benull. As it is possible that a single process contains more than one package thepackageName should be [read](/reference/android/content/Context#getPackageName%28%29) from the context of the caller of the API (in the app process) that eventually triggers this check. If this op is not noted for a running process the packageName cannot be read from the context, but it should be clear which package the note is for.
If the uid and packageName do not match this return[MODE_IGNORED](/reference/android/app/AppOpsManager#MODE%5FIGNORED).
Beside the access check this method also records the access. While the access check is based on uid and/or packageName the access recording is done based on thepackageName and attributionTag. The attributionTag should be[read](/reference/android/content/Context#getAttributionTag%28%29) from the same context the package name is read from. In the case the check is not related to an API call, the attributionTag should benull. Please note that e.g. registering a callback for later is still an API call and the code should store the attribution tag along the package name for being used in this method later.
The message parameter only needs to be set when this method is
not
called in a two-way binder call from the client. In this case the message is a free form text that is meant help the app developer determine what part of the app's code triggered the note. This message is passed back to the app in the[OnOpNotedCallback.onAsyncNoted(AsyncNotedAppOp)](/reference/android/app/AppOpsManager.OnOpNotedCallback#onAsyncNoted%28android.app.AsyncNotedAppOp%29) callback. A good example of a useful message is including the [System.identityHashCode(Object)](/reference/java/lang/System#identityHashCode%28java.lang.Object%29) of the listener that will receive data or the name of the manifest-receiver.
| Parameters | |
|---|---|
| op | String: The operation to note. One of the OPSTR_* constants. This value cannot be null. |
| uid | int: The uid of the application attempting to perform the operation. |
| packageName | String: The name of the application attempting to perform the operation. This value may be null. |
| attributionTag | String: The attribution tag of the calling context or null for default attribution |
| message | String: A message describing why the op was noted. This value may be null. |
| Returns | |
|---|---|
| int | Returns MODE_ALLOWED if the operation is allowed, orMODE_IGNORED if it is not allowed and should be silently ignored (without causing the app to crash). |
| Throws | |
|---|---|
| SecurityException | If the app has been configured to crash on this op. |

This function will verify that the calling uid and proxied package name match, and if not, return [MODE_IGNORED](/reference/android/app/AppOpsManager#MODE%5FIGNORED). If this call succeeds, the last execution time of the operation for the proxied app and your app will be updated to the current time.
| Parameters | |
|---|---|

permissionToOp
public static String permissionToOp (String permission)
Gets the app-op name associated with a given permission.
The app-op name is one of the public constants defined in this class such as [OPSTR_COARSE_LOCATION](/reference/android/app/AppOpsManager#OPSTR%5FCOARSE%5FLOCATION). This API is intended to be used for mapping runtime permissions to the corresponding app-op.
| Parameters | |
|---|---|
| permission | String: The permission. This value cannot be null. |
| Returns | |
|---|---|
| String | The app-op associated with the permission or null. |
setOnOpNotedCallback
public void setOnOpNotedCallback (Executor asyncExecutor, AppOpsManager.OnOpNotedCallback callback)
Set a new [OnOpNotedCallback](/reference/android/app/AppOpsManager.OnOpNotedCallback).
There can only ever be one collector per process. If there currently is another callback set, this will fail.
Note that if an app has multiple processes registering for this callback, the system would fan out async op noted callbacks to each of the processes, resulting in the same data being delivered multiple times to an app, which is usually undesired. To avoid this, consider listening to async ops only in one process. See[setOnOpNotedCallback(Executor,OnOpNotedCallback,int)](/reference/android/app/AppOpsManager#setOnOpNotedCallback%28java.util.concurrent.Executor,%20android.app.AppOpsManager.OnOpNotedCallback,%20int%29) for how to do this.
| Parameters | |
|---|---|
| asyncExecutor | Executor: executor to execute OnOpNotedCallback.onAsyncNoted on, null to unset. Callback and listener events are dispatched through thisExecutor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can useContext.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread. |
| callback | AppOpsManager.OnOpNotedCallback: listener to set, null to unset |
| Throws | |
|---|---|
| IllegalStateException | If another callback is already registered |
setOnOpNotedCallback
public void setOnOpNotedCallback (Executor asyncExecutor, AppOpsManager.OnOpNotedCallback callback, int flags)
Set a new [OnOpNotedCallback](/reference/android/app/AppOpsManager.OnOpNotedCallback).
There can only ever be one collector per process. If there currently is another callback set, this will fail.
This API allows the caller to listen only to sync and self op noted events, and ignore async ops. This is useful in the scenario where an app has multiple processes. Consider an example where an app has two processes, A and B. The op noted events are as follows:
- op 1: process A, sync
- op 2: process A, async
- op 3: process B, sync
- op 4: process B, async Any process that listens to async op noted events gets events originating from across ALL processes (op 2 and op 4 in this example). So if both process A and B register as listeners, both of them get op 2 and 4 which is not ideal. To avoid duplicates, one of the two processes should set
[OP_NOTED_CALLBACK_FLAG_IGNORE_ASYNC](/reference/android/app/AppOpsManager#OP%5FNOTED%5FCALLBACK%5FFLAG%5FIGNORE%5FASYNC). For example process A sets[OP_NOTED_CALLBACK_FLAG_IGNORE_ASYNC](/reference/android/app/AppOpsManager#OP%5FNOTED%5FCALLBACK%5FFLAG%5FIGNORE%5FASYNC)and would then only get its own sync event (op 1). The other process would then listen to all types of events and get op 2, 3 and 4. Note that even with[OP_NOTED_CALLBACK_FLAG_IGNORE_ASYNC](/reference/android/app/AppOpsManager#OP%5FNOTED%5FCALLBACK%5FFLAG%5FIGNORE%5FASYNC),[OnOpNotedCallback.onAsyncNoted](/reference/android/app/AppOpsManager.OnOpNotedCallback#onAsyncNoted%28android.app.AsyncNotedAppOp%29)may still be invoked. This happens for sync events that were collected before a callback is registered.Parameters asyncExecutor Executor: executor to execute OnOpNotedCallback.onAsyncNoted on, null to unset. Callback and listener events are dispatched through thisExecutor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can useContext.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread. callback AppOpsManager.OnOpNotedCallback: listener to set, null to unset flags int: additional flags to modify the callback behavior, such asOP_NOTED_CALLBACK_FLAG_IGNORE_ASYNC Value is either 0 or OP_NOTED_CALLBACK_FLAG_IGNORE_ASYNC Throws ------------------------------------------------------------------- ----------------------------------------- IllegalStateException If another callback is already registered

startWatchingActive
public void startWatchingActive (String[] ops, Executor executor, AppOpsManager.OnOpActiveChangedListener callback)
Start watching for changes to the active state of app-ops. An app-op may be long running and it has a clear start and stop delimiters. If an op is being started or stopped by any package you will get a callback. To change the watched ops for a registered callback you need to unregister and register it again.

| Parameters | |
|---|---|
| ops | String: The operations to watch. This value cannot be null. |
| executor | Executor: Callback and listener events are dispatched through thisExecutor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can useContext.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread. This value cannot be null. |
| callback | AppOpsManager.OnOpActiveChangedListener: Where to report changes. This value cannot be null. |
startWatchingMode
public void startWatchingMode (String op, String packageName, AppOpsManager.OnOpChangedListener callback)

| Parameters | |
|---|---|
| callback | AppOpsManager.OnOpActiveChangedListener: This value cannot be null. |
unsafeCheckOp
public int unsafeCheckOp (String op, int uid, String packageName)
This method was deprecated in API level 36.
Use [checkOp(String,int,String)](/reference/android/app/AppOpsManager#checkOp%28java.lang.String,%20int,%20java.lang.String%29)
Check whether an application might be able to perform an operation.
For platform versions before [Build.VERSION_CODES.BAKLAVA](/reference/android/os/Build.VERSION%5FCODES#BAKLAVA), this is_not_ a security check; you must use [noteOp(String,int,String,String,String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String,%20java.lang.String,%20java.lang.String%29) or [startOp(String,int,String,String,String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String,%20java.lang.String,%20java.lang.String%29) for your actual security checks. This function can just be used for a quick check to see if an operation has been disabled for the application, as an early reject of some work.
For platform versions equal to or after [Build.VERSION_CODES.BAKLAVA](/reference/android/os/Build.VERSION%5FCODES#BAKLAVA), this is no longer an unsafe check, and it does the same security check as [noteOp(String,int,String,String,String)](/reference/android/app/AppOpsManager#noteOp%28java.lang.String,%20int,%20java.lang.String,%20java.lang.String,%20java.lang.String%29) and [startOp(String,int,String,String,String)](/reference/android/app/AppOpsManager#startOp%28java.lang.String,%20int,%20java.lang.String,%20java.lang.String,%20java.lang.String%29). However, it's preferred to use [checkOp(String,int,String)](/reference/android/app/AppOpsManager#checkOp%28java.lang.String,%20int,%20java.lang.String%29), since the word "unsafe" in the name of this API is no longer accurate.
This API does not modify the time stamp or other data about the operation.
| Parameters | |
|---|---|
| op | String: The operation to check. One of the OPSTR_* constants. This value cannot be null. |
| uid | int: The user id of the application attempting to perform the operation. |
| packageName | String: The name of the application attempting to perform the operation. This value cannot be null. |
| Returns | |
|---|---|
| int | Returns MODE_ALLOWED if the operation is allowed, orMODE_IGNORED if it is not allowed and should be silently ignored (without causing the app to crash). |
| Throws | |
|---|---|
| SecurityException | If the app has been configured to crash on this op. |
