copied!<p>I don't succeed in achieving this feature by using these Flags, but I did succeed by using the <a href="http://developer.android.com/reference/android/os/PowerManager.WakeLock.html" rel="noreferrer">WakeLock</a> and <a href="http://developer.android.com/reference/android/app/KeyguardManager.KeyguardLock.html" rel="noreferrer">KeyguardLock</a>. Below is what I do:</p> <pre><code>public class DismissLock extends Activity { PowerManager pm; WakeLock wl; KeyguardManager km; KeyguardLock kl; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); Log.i("INFO", "onCreate() in DismissLock"); pm = (PowerManager) getSystemService(Context.POWER_SERVICE); km=(KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE); kl=km.newKeyguardLock("INFO"); wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP|PowerManager.ON_AFTER_RELEASE, "INFO"); wl.acquire(); //wake up the screen kl.disableKeyguard();// dismiss the keyguard setContentView(R.layout.main); } @Override protected void onPause() { // TODO Auto-generated method stub super.onPause(); wl.release(); //when the activiy pauses, we should realse the wakelock } @Override protected void onResume() { // TODO Auto-generated method stub super.onResume(); wl.acquire();//must call this! } } </code></pre> <p>Of course, you still need to declare the permission in the manifest file.</p> <pre><code><uses-permission android:name="android.permission.WAKE_LOCK"/> <uses-permission android:name="android.permission.DISABLE_KEYGUARD"/> </code></pre>
