Instrumentation

public class Instrumentation
extends Object

java.lang.Object
↳	android.app.Instrumentation

Known direct subclasses

InstrumentationTestRunner

InstrumentationTestRunner This class is deprecated. Use AndroidJUnitRunner instead. New tests should be written using the Android Testing Support Library.

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

REPORT_KEY_IDENTIFIER

public static final String REPORT_KEY_IDENTIFIER

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"

REPORT_KEY_STREAMRESULT

public static final String REPORT_KEY_STREAMRESULT

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.

See also:

addMonitor(Instrumentation.ActivityMonitor)

endPerformanceSnapshot

public void endPerformanceSnapshot ()

finish

public void finish (int resultCode, 
                Bundle results)

Terminate instrumentation of the application. This will cause the application process to exit, removing this instrumentation from the next time the application is started. If multiple processes are currently running for this instrumentation, all of those processes will be killed.

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

getAllocCounts

public Bundle getAllocCounts ()

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

Returns
`Bundle`

getBinderCounts

public Bundle getBinderCounts ()

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`

getComponentName

public ComponentName getComponentName ()

Returns complete component name of this instrumentation.

Returns
`ComponentName`	Returns the complete component name for this instrumentation.

getContext

public Context getContext ()

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:

getTargetContext()

getProcessName

public String getProcessName ()

Return the name of the process this instrumentation is running in. Note this should only be used for testing and debugging. If you are thinking about using this to, for example, conditionalize what is initialized in an Application class, it is strongly recommended to instead use lazy initialization (such as a getter for the state that only creates it when requested). This can greatly reduce the work your process does when created for secondary things, such as to receive a broadcast.

Returns
`String`

getTargetContext

public Context getTargetContext ()

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:

getContext()

getUiAutomation

public UiAutomation getUiAutomation (int flags)

Gets the UiAutomation instance with flags set.

Note: The APIs exposed via the returned UiAutomation work across application boundaries while the APIs exposed by the instrumentation do not. For example, Instrumentation#sendPointerSync(MotionEvent) will not allow you to inject the event in an app different from the instrumentation target, while UiAutomation#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.

If a UiAutomation exists with different flags, the flags on that instance will be changed, and then it will be returned.

Parameters
`flags`	`int`: The flags to be passed to the UiAutomation, for example `UiAutomation#FLAG_DONT_SUPPRESS_ACCESSIBILITY_SERVICES`. Value is 0, or `UiAutomation.FLAG_DONT_SUPPRESS_ACCESSIBILITY_SERVICES`

Returns
`UiAutomation`	The UI automation instance.

See also:

UiAutomation

getUiAutomation

public UiAutomation getUiAutomation ()

Gets the UiAutomation instance with no flags set.

Equivalent to getUiAutomation(0). If a UiAutomation exists with different flags, the flags on that instance will be changed, and then it will be returned.

Returns
`UiAutomation`	The UI automation instance.

onCreate

public void onCreate (Bundle arguments)

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 Context#startActivity to begin the appropriate first activity of the application.

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

onDestroy

public void onDestroy ()

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

onException

public boolean onException (Object obj, 
                Throwable e)

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.

onStart

public void onStart ()

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.

removeMonitor

public void removeMonitor (Instrumentation.ActivityMonitor monitor)

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

Parameters
`monitor`	`Instrumentation.ActivityMonitor`: The monitor to remove.

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.

sendCharacterSync

public void sendCharacterSync (int keyCode)

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.

sendKeyDownUpSync

public void sendKeyDownUpSync (int key)

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

Parameters
`key`	`int`: The integer keycode for the event.

sendKeySync

public void sendKeySync (KeyEvent event)

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.

sendPointerSync

public void sendPointerSync (MotionEvent event)

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 `MotionEvent#obtain(long, long, int, float, float, int)`, be sure to use `SystemClock#uptimeMillis()` as the timebase.

sendStatus

public void sendStatus (int resultCode, 
                Bundle results)

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.

sendStringSync

public void sendStringSync (String text)

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

Parameters
`text`	`String`: The text to be sent.

sendTrackballEventSync

public void sendTrackballEventSync (MotionEvent event)

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 `MotionEvent#obtain(long, long, int, float, float, int)`, be sure to use `SystemClock#uptimeMillis()` as the timebase.

setAutomaticPerformanceSnapshots

public void setAutomaticPerformanceSnapshots ()

setInTouchMode

public void setInTouchMode (boolean inTouch)

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.

start

public void start ()

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

startActivitySync

public Activity startActivitySync (Intent intent, 
                Bundle options)

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 Context#startActivity 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 Activity#onCreate. Generally this means it has gone through the full initialization including Activity#onResume and drawn and displayed its initial window.

Parameters
`intent`	`Intent`: Description of the activity to start. This value cannot be `null`.
`options`	`Bundle`: Additional options for how the Activity should be started. May be null if there are no options. See `ActivityOptions` for how to build the Bundle supplied here; there are no supported definitions for building it manually. This value may be `null`.

Returns
`Activity`

Context.startActivity(Intent, Bundle)

startActivitySync

public Activity startActivitySync (Intent intent)

Parameters
`intent`	`Intent`: Description of the activity to start.

Returns
`Activity`

startAllocCounting

public void startAllocCounting ()

startPerformanceSnapshot

public void startPerformanceSnapshot ()

startProfiling

public void startProfiling ()

This method will start profiling if isProfiling() returns true. You should only call this method if you set the handleProfiling attribute in the manifest file for this Instrumentation to true.

stopAllocCounting

public void stopAllocCounting ()

stopProfiling

public void stopProfiling ()

Stops profiling if isProfiling() returns true.

waitForIdle

public void waitForIdle (Runnable recipient)

Schedule a callback for when the application's main thread goes idle (has no more events to process).

Parameters
`recipient`	`Runnable`: Called the next time the thread's message queue is idle.

waitForIdleSync

public void waitForIdleSync ()

Synchronously wait for the application to be idle. Can not be called from the main application thread -- use start() to execute instrumentation in its own thread.

waitForMonitor

public Activity waitForMonitor (Instrumentation.ActivityMonitor monitor)

Wait for an existing ActivityMonitor to be hit. Once the monitor has been hit, it is removed from the activity monitor list and the first created Activity object that matched it is returned.

Parameters
`monitor`	`Instrumentation.ActivityMonitor`: The ActivityMonitor to wait for.

Returns
`Activity`	The Activity object that matched the monitor.

waitForMonitorWithTimeout

public Activity waitForMonitorWithTimeout (Instrumentation.ActivityMonitor monitor, 
                long timeOut)

Wait for an existing ActivityMonitor to be hit till the timeout expires. Once the monitor has been hit, it is removed from the activity monitor list and the first created Activity object that matched it is returned. If the timeout expires, a null object is returned.

Parameters
`monitor`	`Instrumentation.ActivityMonitor`: The ActivityMonitor to wait for.
`timeOut`	`long`: The timeout value in milliseconds.

Returns
`Activity`	The Activity object that matched the monitor.
