Hi All, Can you guys help me solve the problem below? For ICS, it is easy to do the screen shot manually, by press the POWER and Volumn_Down key same time, and there is a instrument test under / icecreamsandwich/frameworks/base/packages/SystemUI/tests/ ,
101 /** 102 * Inject the key sequence to take a screenshot. 103 */ 104 private void takeScreenshot() { 105 getInstrumentation().sendKeySync(new KeyEvent(KeyEvent.ACTION_DOWN, 106 KeyEvent.KEYCODE_POWER)); 107 getInstrumentation().sendKeySync(new KeyEvent(KeyEvent.ACTION_DOWN, 108 KeyEvent.KEYCODE_VOLUME_DOWN)); 109 try{ 110 Thread.sleep(2000); 111 }catch(Exception e){ 112 } 113 // the volume down key event will cause the 'volume adjustment' UI to appear in the 114 // foreground, and steal UI focus 115 // unfortunately this means the next key event will get directed to the 116 // 'volume adjustment' UI, instead of this test's activity 117 // for this reason this test must be signed with platform certificate, to grant this test 118 // permission to inject key events to another process 119 getInstrumentation().sendKeySync(new KeyEvent(KeyEvent.ACTION_UP, 120 KeyEvent.KEYCODE_VOLUME_DOWN)); 121 getInstrumentation().sendKeySync(new KeyEvent(KeyEvent.ACTION_UP, 122 KeyEvent.KEYCODE_POWER)); 123 } and in it's AndroidManifest.xml file, there is the user-permission flag: <uses-permission android:name="android.permission.INJECT_EVENTS" /> I tried it, and it works, it can take the screenshot. Now I want to borrow this code a camera test case, it also use the instrument, I add the android.permission.INJECT_EVENTS in menifest.xml, (but this doesn't exist in Camera app's AndroidManifest.xml), andI run case, only see the volume adjustment' UI appear in the ui. Seems that the getInstrumentation().sendKeySync(new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_POWER)), didn't run or take effect. Is it because the camera APP's AndroidMenifest.xml doesn't include the <uses-permission android:name="android.permission.INJECT_EVENTS" />? why, -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
