AppOpsManager


open class AppOpsManager
kotlin.Any
   ↳ android.app.AppOpsManager

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
Default behavior, might differ from app-op or app-op
MODE_ALLOWED
Allow the access
MODE_IGNORED
Don't allow the access, i.e. don't perform the requested action or return no or placeholder data
MODE_ERRORED
Throw a 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 if they are are allowing access to operations gated by the app-op. unsafeCheckOp 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 anyway.

If an operation refers to a time span (e.g. a audio-recording session) the API provider should use #startOp and #finishOp instead of #noteOp.

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, but if the permission is granted and the app-op is MODE_IGNORED 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 check the permission grant state. If the app-op state is set to MODE_ALLOWED or MODE_IGNORED 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 #noteOp or #startOp. The tracked data can only be read by system components.

Only #noteOp/#startOp are tracked; unsafeCheckOp is not tracked. Hence it is important to eventually call #noteOp or #startOp 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 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 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_ALLOWED

Added in API level 19
static val MODE_ALLOWED: Int

Result from checkOp, #noteOp, #startOp: the given caller is allowed to perform the given operation.

Value: 0

MODE_DEFAULT

Added in API level 21
static val MODE_DEFAULT: Int

Result from checkOp, #noteOp, #startOp: the given caller should use its default security check. This mode is not normally used; it should only be used with appop permissions, and callers must explicitly check for it and deal with it.

Value: 3

MODE_ERRORED

Added in API level 19
static val MODE_ERRORED: Int

Result from checkOpNoThrow, #noteOpNoThrow, #startOpNoThrow: 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.

Value: 2

MODE_FOREGROUND

Added in API level 29
static val MODE_FOREGROUND: Int

Special mode that means "allow only when app is in foreground." This is not returned from unsafeCheckOp, #noteOp, #startOp. Rather, unsafeCheckOp will always return MODE_ALLOWED (because it is always possible for it to be ultimately allowed, depending on the app's background state), and #noteOp and #startOp will return MODE_ALLOWED when the app being checked is currently in the foreground, otherwise MODE_IGNORED.

The only place you will this normally see this value is through unsafeCheckOpRaw, 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 and MODE_IGNORED depending on changes in the background state of the app. You thus must always use #noteOp or #startOp to do the actual check for access to the op.

Value: 4

MODE_IGNORED

open fun noteOp(
    op: String,
    uid: Int,
    packageName: String?,
    attributionTag: String?,
    message: String?
): Int

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 instead.

The identity of the package the app-op is noted for is specified by the uid 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 be null. As it is possible that a single process contains more than one package the packageName should be read 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.

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 the packageName and attributionTag. The attributionTag should be read 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 be null. 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) callback. A good example of a useful message is including the System#identityHashCode(Object) 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.
Return
Int Returns MODE_ALLOWED if the operation is allowed, or MODE_IGNORED if it is not allowed and should be silently ignored (without causing the app to crash).
Exceptions
java.lang.SecurityException If the app has been configured to crash on this op.

): Unit

Set a new OnOpNotedCallback.

There can only ever be one collector per process. If there currently is another callback set, this will fail.

Parameters
asyncExecutor Executor?: executor to execute OnOpNotedCallback#onAsyncNoted on, null to unset Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread.

    executor: Executor,
    callback: AppOpsManager.OnOpActiveChangedListener
): Unit

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 Array<String!>: The operations to watch. This value cannot be null.
callback AppOpsManager.OnOpActiveChangedListener: Where to report changes. This value cannot be null.
executor Executor: Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread. This value cannot be null.

stopWatchingMode

Added in API level 19
open fun stopWatchingMode(callback: AppOpsManager.OnOpChangedListener): Unit

Stop monitoring that was previously started with #startWatchingMode. All monitoring associated with this callback will be removed.

unsafeCheckOp

Added in API level 29
open fun unsafeCheckOp(
    op: String,
    uid: Int,
    packageName: String
): Int

Do a quick check for whether an application might be able to perform an operation. This is not a security check; you must use noteOp(java.lang.String,int,java.lang.String,java.lang.String,java.lang.String) or startOp(java.lang.String,int,java.lang.String,java.lang.String,java.lang.String) for your actual security checks, which also ensure that the given uid and package name are consistent. 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. This does not modify the time stamp or other data about the operation.

Important things this will not do (which you need to ultimate use noteOp(java.lang.String,int,java.lang.String,java.lang.String,java.lang.String) or startOp(java.lang.String,int,java.lang.String,java.lang.String,java.lang.String) to cover):

  • Verifying the uid and package are consistent, so callers can't spoof their identity.
  • Taking into account the current foreground/background state of the app; apps whose mode varies by this state will always be reported as MODE_ALLOWED.
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.
Return
Int Returns MODE_ALLOWED if the operation is allowed, or MODE_IGNORED if it is not allowed and should be silently ignored (without causing the app to crash).
Exceptions
java.lang.SecurityException If the app has been configured to crash on this op.
