I want to implement a background task in my android application. For Android 5.0 and lower, my code suffices with a simple BroadcastReceiver, where I can easily set an repeating alarm with
setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * seconds, pendingIntent);
On Android 6.0, however, I found out to replace my BroadcastReceiver with WakefulBroadcastReceiver and
setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), pendingIntent);
It is still not working at all and I don't know what my mistake is..
Here my code:
public class AlarmManagerBroadcastReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
mContext = context;
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG");
//Acquire the lock
wl.acquire();
callback = new GPSActivityCallback() {...}
if(isConnectedToInternet()) {
gpsService = new GPSService(callback, context);
gpsService.refreshLocation();
Bundle extras = intent.getExtras();
StringBuilder msgStr = new StringBuilder();
if (extras != null && extras.getBoolean(REPEAT, Boolean.FALSE)) {
//Make sure this intent has been sent by the one-time timer button.
}
Format formatter = new SimpleDateFormat("hh:mm:ss a");
msgStr.append(formatter.format(new Date()));
}
else {
Toast.makeText(context, "Internetverbindung wurde unterbrochen", Toast.LENGTH_SHORT).show();
Log.d("INTERNET_TAG","Internetverbindung war kurrzeitig getrennt");
}
wl.release();
public void SetAlarm(Context context) {
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);
intent.putExtra(REPEAT, Boolean.FALSE);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
if(Build.VERSION.SDK_INT < 23){
if(Build.VERSION.SDK_INT >= 19){
am.setExact(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), pi);
}
else{
am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), pi);
}
}
else{
am.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), pi);
}
am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 10, pi);
}
public boolean isConnectedToInternet(){...}
}

I have an app developed in java whose function is to capture the location when the app is active, background, destroyed and when the phone restarts
I already managed to capture the location when the app is active, background and destroyed but I am trying to do it when the phone reboots and create the task to capture but it says that the task was configured well but it does not execute it every 1 minute

I am testing the app on a samsung A13 with android 12
I have some trouble ring an alarm on android-studio app. First, I have a method, called with a button ( onClick), then I create alarmManager in this, and try to call a class AlarmReceiver to ring the alarm. The problem is that the program running never go in my AlarmReceiver class, and I don't understand why. Let me show you the code:
public void sendMessage(View v) {
long time = currentTimeMillis();
Toast.makeText(this, "ALARM ON", Toast.LENGTH_SHORT).show();
alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(MainActivity.this, AlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 14);
calendar.set(Calendar.MINUTE, 58);
Toast.makeText(MainActivity.this, "bjr", Toast.LENGTH_SHORT).show();
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),pendingIntent);}
This is the method called when click on button, and now this is the AlarmReceiver:
public class AlarmReceiver extends WakefulBroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
Toast.makeText(context, "Alarm! Wake up! Wake up!", Toast.LENGTH_LONG).show();
Uri alarmUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
if (alarmUri == null)
{
alarmUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
}
Ringtone ringtone = RingtoneManager.getRingtone(context, alarmUri);
ringtone.play();
}
}
So, when I run the app, then click on button, the word " ALARM ON" and "bjr" is printed, but the text so in AlarmReceiver "Alarm! Wake up!" Is never printed, so the app never go in this class, I need to know why.

I have looked at several questions on this site and none seem to be able to answer my question so hopefully someone can help with this. Currently for some reason when I send a message through from the PHP Website, my app doesn't receive the message. I have tried placing Log.d's in the lines of code but it doesn't appear as well. Can someone help to see if something has gone wrong?
[UPDATE] This is the result when I send from the php website
{"multicast_id":5610818169388245295,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1460536959734990%40ad5721f9fd7ecd"}]}

I seem to be having trouble getting my onReceive class receive any broadcasts I send out. Im not sure if its my code thats the problem or its a problem with the Android Manifest.
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.i("BROADCAST_RECEIVED", intent.getDataString());
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wakeLock = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP, "");
wakeLock.acquire();
wakeLock.release();
context.startActivity(intent);
}
}
public void setDayOfWeekAlarm(DayOfWeek day){
long alarmInMili = 0;
Intent intent = new Intent(context,AlarmScreenActivity.class);
alarmInMili = System.currentTimeMillis() + 1000*10;
Log.i("REGISTER ALARM", String.valueOf(alarmInMili));
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP,SystemClock.elapsedRealtime() +
10 * 1000,pi);
}

In addition to Gabe's answer, the Intent that you are using in setDayOfWeekAlarm() points to AlarmScreenActivity. That is not your BroadcastReceiver, nor is it any other component registered in your manifest.
BOOT_COMPLETED receivers cannot recieve a broadcast until an activity in the apk has been launched at least once. Its a weird rule google added to prevent people from downloading an app by mistake and having it run at boot.
My service don't start on system boot, only when the user press the refresh button. I've tried everythng searched in stack but nothing i've rewrited my code 4 times and nothing, i want my service run in a time interval and when the refresh button is pressed, i can´t understand why is not running on boot, Have i missed something?

NOTES:
i already tried starting the service directly without filters, but
for no reason don't start, so with filters was the only way that
worked.
I also tried without the StartServiceReceiver.java, with the intent inside the alarm but no luck, i can change the code again if somebody thinks that its the problem.
I've the while(isRunning) in the thread only for future purpose, but i think the problem it's not because this.
Compared with one of my implementations, there're small differences in the manifest:
used permissions (seems to be equal with yours
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
The Receiver
<receiver
android:name="com.<!your activity!>"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Yoiu see that there's an additional entry about the permission.
