Class Overview

Base class for implementing application instrumentation code. When running with instrumentation turned on, this class will be instantiated for you before any of the application code, allowing you to monitor all of the interaction the system has with the application. An Instrumentation implementation is described to the system through an AndroidManifest.xml's <instrumentation> tag.

Constants

public static final String REPORT_KEY_IDENTIFIER

Added in API level 1

If included in the status or final bundle sent to an IInstrumentationWatcher, this key identifies the class that is writing the report. This can be used to provide more structured logging or reporting capabilities in the IInstrumentationWatcher.

Constant Value: "id"

public static final String REPORT_KEY_STREAMRESULT

Added in API level 1

If included in the status or final bundle sent to an IInstrumentationWatcher, this key identifies a string which can simply be printed to the output stream. Using these streams provides a "pretty printer" version of the status & final packets. Any bundles including this key should also include the complete set of raw key/value pairs, so that the instrumentation can also be launched, and results collected, by an automated system.

Constant Value: "stream"

Parameters
app Application: The application being created.

public boolean checkMonitorHit (Instrumentation.ActivityMonitor monitor, int minHits)

Added in API level 1

Test whether an existing Instrumentation.ActivityMonitor has been hit. If the monitor has been hit at least minHits times, then it will be removed from the activity monitor list and true returned. Otherwise it is left as-is and false is returned.

Terminate instrumentation of the application. This will cause the application process to exit, removing this instrumentation from the next time the application is started.

Parameters
resultCode int: Overall success/failure of instrumentation.
results Bundle: Any results to send back to the code that started the instrumentation.

public Bundle getAllocCounts ()

Added in API level 1

Returns a bundle with the current results from the allocation counting.

Returns
Bundle

public Bundle getBinderCounts ()

Added in API level 1

Returns a bundle with the counts for various binder counts for this process. Currently the only two that are reported are the number of send and the number of received transactions.

Returns
Bundle

public ComponentName getComponentName ()

Added in API level 1

Returns complete component name of this instrumentation.

Returns
ComponentName Returns the complete component name for this instrumentation.

public Context getContext ()

Added in API level 1

Return the Context of this instrumentation's package. Note that this is often different than the Context of the application being instrumentated, since the instrumentation code often lives is a different package than that of the application it is running against. See getTargetContext() to retrieve a Context for the target application.

Returns
Context The instrumentation's package context.

See also:

public Context getTargetContext ()

Added in API level 1

Return a Context for the target application being instrumented. Note that this is often different than the Context of the instrumentation code, since the instrumentation code often lives is a different package than that of the application it is running against. See getContext() to retrieve a Context for the instrumentation code.

Returns
Context A Context in the target application.

See also:

public UiAutomation getUiAutomation ()

Added in API level 18

Gets the UiAutomation instance.

Note: The APIs exposed via the returned UiAutomation work across application boundaries while the APIs exposed by the instrumentation do not. For example, sendPointerSync(MotionEvent) will not allow you to inject the event in an app different from the instrumentation target, while injectInputEvent(android.view.InputEvent, boolean) will work regardless of the current application.

A typical test case should be using either the UiAutomation or Instrumentation APIs. Using both APIs at the same time is not a mistake by itself but a client has to be aware of the APIs limitations.

Returns
UiAutomation The UI automation instance.

public void onCreate (Bundle arguments)

Added in API level 1

Called when the instrumentation is starting, before any application code has been loaded. Usually this will be implemented to simply call start() to begin the instrumentation thread, which will then continue execution in onStart().

If you do not need your own thread -- that is you are writing your instrumentation to be completely asynchronous (returning to the event loop so that the application can run), you can simply begin your instrumentation here, for example call startActivity(Intent) to begin the appropriate first activity of the application.

Parameters
arguments Bundle: Any additional arguments that were supplied when the instrumentation was started.

public void onDestroy ()

Added in API level 1

Called when the instrumented application is stopping, after all of the normal application cleanup has occurred.

public boolean onException (Object obj, Throwable e)

Added in API level 1

This is called whenever the system captures an unhandled exception that was thrown by the application. The default implementation simply returns false, allowing normal system handling of the exception to take place.

Parameters
obj Object: The client object that generated the exception. May be an Application, Activity, BroadcastReceiver, Service, or null.
e Throwable: The exception that was thrown.
Returns
boolean To allow normal system exception process to occur, return false. If true is returned, the system will proceed as if the exception didn't happen.

public void onStart ()

Added in API level 1

Method where the instrumentation thread enters execution. This allows you to run your instrumentation code in a separate thread than the application, so that it can perform blocking operation such as sendKeySync(KeyEvent) or startActivitySync(Intent).

You will typically want to call finish() when this function is done, to end your instrumentation.

public void removeMonitor (Instrumentation.ActivityMonitor monitor)

Added in API level 1

Remove an Instrumentation.ActivityMonitor that was previously added with addMonitor(Instrumentation.ActivityMonitor).

Parameters
monitor Instrumentation.ActivityMonitor: The monitor to remove.

public void runOnMainSync (Runnable runner)

Added in API level 1

Execute a call on the application's main thread, blocking until it is complete. Useful for doing things that are not thread-safe, such as looking at or modifying the view hierarchy.

Parameters
runner Runnable: The code to run on the main thread.

public void sendCharacterSync (int keyCode)

Added in API level 1

Higher-level method for sending both the down and up key events for a particular character key code. Equivalent to creating both KeyEvent objects by hand and calling sendKeySync(KeyEvent). The event appears as if it came from keyboard 0, the built in one.

Parameters
keyCode int: The key code of the character to send.

public void sendKeyDownUpSync (int key)

Added in API level 1

Sends an up and down key event sync to the currently focused window.

Parameters
key int: The integer keycode for the event.

public void sendKeySync (KeyEvent event)

Added in API level 1

Send a key event to the currently focused window/view and wait for it to be processed. Finished at some point after the recipient has returned from its event processing, though it may not have completely finished reacting from the event -- for example, if it needs to update its display as a result, it may still be in the process of doing that.

Parameters
event KeyEvent: The event to send to the current focus.

public void sendPointerSync (MotionEvent event)

Added in API level 1

Dispatch a pointer event. Finished at some point after the recipient has returned from its event processing, though it may not have completely finished reacting from the event -- for example, if it needs to update its display as a result, it may still be in the process of doing that.

Parameters
event MotionEvent: A motion event describing the pointer action. (As noted in obtain(long, long, int, float, float, int), be sure to use uptimeMillis() as the timebase.

public void sendStatus (int resultCode, Bundle results)

Added in API level 1

Provide a status report about the application.

Parameters
resultCode int: Current success/failure of instrumentation.
results Bundle: Any results to send back to the code that started the instrumentation.

public void sendStringSync (String text)

Added in API level 1

Sends the key events corresponding to the text to the app being instrumented.

Parameters
text String: The text to be sent.

public void sendTrackballEventSync (MotionEvent event)

Added in API level 1

Dispatch a trackball event. Finished at some point after the recipient has returned from its event processing, though it may not have completely finished reacting from the event -- for example, if it needs to update its display as a result, it may still be in the process of doing that.

Parameters
event MotionEvent: A motion event describing the trackball action. (As noted in obtain(long, long, int, float, float, int), be sure to use uptimeMillis() as the timebase.

public void setAutomaticPerformanceSnapshots ()

Added in API level 1

public void setInTouchMode (boolean inTouch)

Added in API level 1

Force the global system in or out of touch mode. This can be used if your instrumentation relies on the UI being in one more or the other when it starts.

Parameters
inTouch boolean: Set to true to be in touch mode, false to be in focus mode.

public void start ()

Added in API level 1

Create and start a new thread in which to run instrumentation. This new thread will call to onStart() where you can implement the instrumentation.

public Activity startActivitySync (Intent intent)

Added in API level 1

Start a new activity and wait for it to begin running before returning. In addition to being synchronous, this method as some semantic differences from the standard startActivity(Intent) call: the activity component is resolved before talking with the activity manager (its class name is specified in the Intent that this method ultimately starts), and it does not allow you to start activities that run in a different process. In addition, if the given Intent resolves to multiple activities, instead of displaying a dialog for the user to select an activity, an exception will be thrown.

The function returns as soon as the activity goes idle following the call to its onCreate(Bundle). Generally this means it has gone through the full initialization including onResume() and drawn and displayed its initial window.

Parameters
intent Intent: Description of the activity to start.
Returns
Activity

public void startAllocCounting ()

Added in API level 1

public void startPerformanceSnapshot ()

Added in API level 1
