    text
    copied!<p>I'm developing an application in which I'm using an <code>activity</code> which will come on top of default lock screen of the device. All things are perfectly fine, but I'm having issues with <code>display timeout of the screen</code>. Every time when my <code>activity</code> comes, the device does not go into sleep mode. Why?</p> <p>Here is my code snippet for <code>Service</code> class and <code>BroadcastReceiver</code> class. I could find out what is hindering the device screen timeout mode.</p> <p><strong>BroadcastReceiver class</strong></p> <pre><code>@Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) { wasScreenOn = false; Intent intent11 = new Intent(context, LockActivity.class); intent11.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent11); } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) { wasScreenOn = true; Intent intent11 = new Intent(context, LockActivity.class); intent11.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); } else if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) { Intent intent11 = new Intent(context, LockActivity.class); intent11.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent11); } } </code></pre> <p><strong>Service Class</strong></p> <pre><code>public class PerkLockService extends Service { BroadcastReceiver mReceiver; @Override public IBinder onBind(Intent intent) { return null; } @SuppressWarnings("deprecation") @Override public void onCreate() { KeyguardManager.KeyguardLock k1; KeyguardManager km = (KeyguardManager) getSystemService(KEYGUARD_SERVICE); k1 = km.newKeyguardLock("IN"); k1.disableKeyguard(); IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON); filter.addAction(Intent.ACTION_SCREEN_OFF); mReceiver = new PerkLockReceiver(); registerReceiver(mReceiver, filter); System.out.println("Service Created"); super.onCreate(); } @Override public void onDestroy() { System.out.println("Service Destroyed"); unregisterReceiver(mReceiver); stopSelf(); super.onDestroy(); } </code></pre> <p>Here is what I'm using <code>permissions</code> in the manifest</p> <pre><code>&lt;uses-permission android:name="android.permission.DISABLE_KEYGUARD" /&gt; &lt;uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /&gt; &lt;uses-permission android:name="android.permission.READ_PHONE_STATE" /&gt; &lt;uses-permission android:name="android.permission.WRITE_SETTINGS" /&gt; &lt;uses-permission android:name="android.permission.INTERNET" /&gt; &lt;uses-permission android:name="android.permission.VIBRATE" /&gt; </code></pre> <p><strong>Update:</strong></p> <p>Adding my <code>MainAcitivty.java</code> from where I'm calling my service and <code>StateListener()</code> method:</p> <p><code>MainActivity.java</code></p> <pre><code>try { // initialize receiver startService(new Intent(this, PerkLockService.class)); StateListener phoneStateListener = new StateListener(); TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE); telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE); } catch (Exception e) { e.printStackTrace(); } /** * Listen to the state of the phone, like ringing and alarm, and it * automatically dismiss the activity and show up the proper screen */ class StateListener extends PhoneStateListener { @Override public void onCallStateChanged(int state, String incomingNumber) { super.onCallStateChanged(state, incomingNumber); switch (state) { case TelephonyManager.CALL_STATE_RINGING: finish(); break; case TelephonyManager.CALL_STATE_OFFHOOK: System.out.println("call Activity off hook"); finish(); break; case TelephonyManager.CALL_STATE_IDLE: break; } } }; </code></pre> <p>I could not find what is keeping the device to go to sleep with my app.</p> <p>Any kind of help will be appreciated.</p>
