Hi,
i am trying to invoke the switch off dialog box that appears when we press power button. But i want to accomplish this task from an android application or a Junit test case. I will choose the most feasible approach in this case. I have been trying to do this but was not able to succeed. I am trying to use the following five approaches:
First approach:
===============================================
long eventTime = SystemClock.uptimeMillis(); boolean
* dispateched = launcherButtonWInst.dispatchKeyEvent(new
* KeyEvent(eventTime, eventTime, KeyEvent.ACTION_DOWN,
* KeyEvent.KEYCODE_POWER, 0, 0, 0, 0, 0) );
* Log.i(LOG_TAG,String.valueOf(dispateched)); boolean
* dispateched2=launcherButtonWInst.dispatchKeyEvent(new
* KeyEvent(eventTime+2000, eventTime+2000, KeyEvent.ACTION_UP,
* KeyEvent.KEYCODE_POWER, 0, 0, 0, 0, 0) );
* Log.i(LOG_TAG,String.valueOf(dispateched2));
=======================================================
Second apporach:
=====================================================
private void generateKeys() {
// Obtain the WindowManager system service interface
IBinder wmbinder = ServiceManager.getService("window");
Log.d(LOG_TAG, "WindowManager: " + wmbinder);
IWindowManager wm = IWindowManager.Stub.asInterface(wmbinder);
keyUpDown(wm, KeyEvent.KEYCODE_POWER);
}
private void keyUpDown(IWindowManager wm, int keycode) {
try {
Log.d(LOG_TAG, "keyDown: " + keycode);
wm.injectKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, keycode), true);
Log.d(LOG_TAG, "keyUp: " + keycode);
wm.injectKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, keycode), true);
} catch (RemoteException e) {
// TODO Auto-generated catch block
Log.e("ERROR!!!!!", e.toString());
e.printStackTrace();
}
}
============================================================
Third approach:
========================================================
Instrumentation inst = new Instrumentation();
inst.sendKeyDownUpSync(KeyEvent.KEYCODE_POWER);
======================================================
Fourth approach:
======================================================
try {
// long now =SystemClock.uptimeMillis();
// KeyEvent down = new KeyEvent(now, now,
// KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_POWER, 0);
//
// Log.d( LOG_TAG,down.toString() );
// KeyEvent up = new KeyEvent(now+2000, now+2000,
// KeyEvent.ACTION_UP, KeyEvent.KEYCODE_POWER, 0);
// Log.d( LOG_TAG,up.toString() );
// (IWindowManager.Stub.asInterface(ServiceManager.getService("window"))).injectKeyEvent(down,
// true);
// try {
// Thread.sleep(2000);
// } catch (InterruptedException e) {
// // TODO Auto-generated catch block
// e.printStackTrace();
// }
// (IWindowManager.Stub.asInterface(ServiceManager.getService("window"))).injectKeyEvent(up,
// true);
// } catch (RemoteException e) {
// Log.d("LOGTAG",
// "SendKeyEvent exception:"+e.getMessage());
// }
================================================================
Fifth approach:
================================================================
try {
Context mContext = getBaseContext();
Dialog dialog=new Dialog(mContext);
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
ShutdownThread.shutdown(mContext, true);
} catch (Exception e) {
Log.e("ERROR!!!", e.toString());
e.printStackTrace();
}
===================================================================
But none of them is working for me. The fifth approach is invoking shutdown() method of ShutdownThread class. But it gives me following error:
07-05 10:18:21.489: W/System.err(709): android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@4104d798 -- permission denied for this window type

07-05 10:18:21.509: W/System.err(709): at dalvik.system.NativeStart.main(Native Method)
Other approaches does not throw any error. I need help to accomplish this task, which ever way it takes even though i have to invoke native methods to accomplish i will do that, but i have to display the the switch off UI.
thanks
