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,
