I need to set up an alarm daily at a given hour. I'm programming the alarm using AlarmManager.RTC_WAKEUP , so it uses the system time as reference. I'm setting the alarm to first execute at the desired hour, then to repeat daily: alarmManager.setRepeating( AlarmManager.RTC_WAKEUP, getTimestampToday("12:00"), AlarmManager.INTERVAL_DAY, pendingIntent ); The getTimestampToday method returns a long timestamp for today at the desired hour. It does so by obtaining the local date for today, then setting the desired hour, finally converting it back to a timestamp (which is UTC based). The problem here

I am trying to do a list of Android task killers that are installed by default on the operating system. The problem is that Android is modified by the phone's manufacturer and it is hard to keep up with what everyone is doing. So far I have found this: Smart manager - On Samsung phones. Could not call alarm manager but you can avoid this if your package name contains "alarm" or "alert" Doze - On Android 6. should not interrupt the app but it may delay alarm manager or network processes(especially if your app is not active and your phone is not charging). Xiaomi , AutoStart . If AutoStart is

Currently i am working on a Broadcast Receiver application, in which i am making an Alarm which should display a message after we enter the seconds. I used RTC_WAKEUP, which means it should display the message when the device is on and it is supposed to turn on the device and then display the message when the device is off. MY PROBLEM IS THAT IT RTC_WAKEUP DOESN'T ON MY DEVICE but it is working properly when device is on. i am pasting the code of my application. In my application there are two classes. MainActivity public class MainActivity extends Activity { @Override public void onCreate

Is there any way to detect outgoing call is successfully received or answered ? I am using Intent.ACTION_CALL for dialing a call and PhoneCallListener to find the state of a call when outgoing call answered but I couldn't have been achieving this. Is this possible in android ? Mohammad Qandeel After deeply working on this issue, I reached this conclusion: PhoneStateListener won't work for outgoing calls, it calls OFFHOOK instead of RINGING and OFFHOOK is never called on ANSWER. Using NotificationListenerService , you can listen to posted notifications related to outgoing calls. You can do

I have a crash that keeps occurring on 4.4.2 and 4.4.3 devices (although I'm not sure this is an API issue), where in some ParsePushBroadcastReceiver the following code causes a NullPointerException somewhere deep inside the startActivities call. Intent intent = new Intent(context, SomeActivity.class); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); TaskStackBuilder.create(context) .addParentStack(SomeActivity.class) .addNextIntent(intent) .startActivities(); I have tried testing to see whether the context was null, however, the Intent instantiation would've caught that. It might also be worth

I'm trying to register receiver, that will check VPN status. I have tried this: Get VPN Connection status on Android but looks like it no longer works on ICS. I have checked android source code for some clue, but with no luck, only noticed that in ISC there is nothing like: vpn.connectivity and connection_state - it use to be in android 2.3. Also tried using android.net.conn.CONNECTIVITY_CHANGE as my IntentFilter , but it doesn't react on VPN connection at all (of course I have added permission android.permission.ACCESS_NETWORK_STATE ). I thought that it is simple thing to do, but I already
