/**
 * App-ops are used for two purposes: Access control and tracking.
 *
 * <p>App-ops cover a wide variety of functionality from helping with runtime permissions access
 * control and tracking to battery consumption tracking.
 *
 * <h2>Access control</h2>
 *
 * <p>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.
 *
 * <p>To control access the app-op can be set to a mode to:
 * <dl>
 *     <dt>{@link #MODE_DEFAULT}
 *     <dd>Default behavior, might differ from app-op or app-op
 *     <dt>{@link #MODE_ALLOWED}
 *     <dd>Allow the access
 *     <dt>{@link #MODE_IGNORED}
 *     <dd>Don't allow the access, i.e. don't perform the requested action or return no or dummy
 *     data
 *     <dt>{@link #MODE_ERRORED}
 *     <dd>Throw a {@link SecurityException} on access. This can be suppressed by using a
 *     {@code ...noThrow} method to check the mode
 * </dl>
 *
 * <p>API providers need to check the mode returned by {@link #noteOp} if they are are allowing
 * access to operations gated by the app-op. {@link #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 {@link #noteOp} anyway.
 *
 * <p>If an operation refers to a time span (e.g. a audio-recording session) the API provider
 * should use {@link #startOp} and {@link #finishOp} instead of {@link #noteOp}.
 *
 * <h3>Runtime permissions and app-ops</h3>
 *
 * <p>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 {@link SecurityException}, but if the permission is
 * granted and the app-op is {@link #MODE_IGNORED} then the callers gets dummy behavior, e.g.
 * location callbacks would not happen.
 *
 * <h3>App-op permissions</h3>
 *
 * <p>App-ops permissions are platform defined permissions that can be overridden. The security
 * check for app-op permissions should by {@link #MODE_DEFAULT default} check the permission grant
 * state. If the app-op state is set to {@link #MODE_ALLOWED} or {@link #MODE_IGNORED} the app-op
 * state should be checked instead of the permission grant state.
 *
 * <p>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.
 *
 * <h2>Tracking</h2>
 *
 * <p>App-ops track many important events, including all accesses to runtime permission protected
 * APIs. This is done by tracking when an app-op was {@link #noteOp noted} or
 * {@link #startOp started}. The tracked data can only be read by system components.
 *
 * <p><b>Only {@link #noteOp}/{@link #startOp} are tracked; {@link #unsafeCheckOp} is not tracked.
 * Hence it is important to eventually call {@link #noteOp} or {@link #startOp} when providing
 * access to protected operations or data.</b>
 *
 * <p>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 {@link #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.
 *
 * <p>An app can register an {@link 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.
