I have a problem and that is that the service I use in an Android project does not work when I disconnect the device from the power. If it is connected, it does work. I have tried many alternatives and the last thing I tried is this.
I need help... anything that can solve this problem?

I want to have an app that do s.th in specific time even phone is on sleep mode. I used these code but receiver dosent work correctly. The Log just show some times. for example every two or three minute Log showed. what should I do that app work when time changed on phone.
I also tried wakeLock and alertManager class but nothing changed.

It's supposed to be a simple to do list app. You can set a list Item with a task and time. It should send you a notification at the given time.
Everything works fine when the app is running but when I close it I don't get notifications. I tried on API 23 and API R. I was looking at other posts but I couldn't find any solution.
Receiver class:
public class AlertReceiver extends BroadcastReceiver {
NotificationManagerCompat notificationManager;
#Override
public void onReceive(Context context, Intent intent) {
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
boolean is24HourFormat = android.text.format.DateFormat.is24HourFormat(context);
CharSequence setTime;
if (is24HourFormat) {
setTime = DateFormat.format("HH:mm", calendar);
} else {
setTime = DateFormat.format("hh:mm a", calendar);
}
String currentTime = setTime.toString();
DataBaseHelper dataBaseHelper = new DataBaseHelper(context);
Item itemForNotificationText = dataBaseHelper.GetNotificationContent(currentTime);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
Notification notification = new NotificationCompat.Builder(context,CHANNEL_1_ID)
.setSmallIcon(R.drawable.ic_baseline_notifications_active_24)
.setContentTitle(itemForNotificationText.getTask())
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.setContentText(itemForNotificationText.getTime())
.build();
notificationManager.notify(dataBaseHelper.GetID(),notification);
}
}
I tired using setExactAndAllowWhileIdle but still doesn't work.
Start alarm:
public void startAlarm (Calendar c){
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlertReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, item.getNotification_id(), intent,0);
if (c.before(Calendar.getInstance())) {
c.add(Calendar.DATE, 1);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
alarmManager.setExact(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),pendingIntent);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),pendingIntent);
}
}

I'm having trouble with an android service that I'm doing. The service is about to get the location of the user every 5 minutes. All seems to go well except when i kill the app, the service won't do nothing. In the code you will ses its checking every 60 seconds I think, but this will change to 5 minutes.

AlarmManager is deprecated if used for that purpose. Have a look at WorkManager.
I try to start a ForegroundService by an BroadcastReceiver on Boot. I have tried this on a device with Android 8 and on an emulated Android 10 device. Both work fine. The problem is, that this code does not work on my Android 10 Galaxy S9. I have debugged everything, my BroadcastReceiver and the OnStartCommand method but also if the BroadcastReceiver runs the code fine, the OnStartCommand method does not start running.
I have a mainActivity in which the user has to apply this Process so the app gets opened once before the BroadcastReceiver should work.
I tried almost every solution i found here but nothing worked for me.
I don't understand why this is working on some devices but not on each. I hope someone can help me!
My min API is 26.

Went through the documentation on how to start a service automatically after the device boots and tried all they said but couldn't get my service to work after rebooting the device, though it works perfectly well on first instance.
Below is my main activity (MainActivity.java) which starts the service after a button has been clicked, and triggers the service every 10 seconds using AlarmManager.
public void onClickSubmitDate(View view) {
Intent service = new Intent(this, MyService.class);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, service, 0);
AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, 0, 10 * 1000, pendingIntent);
//Enable receiver when device boots
ComponentName receiver = new ComponentName(this, BootReceiver.class);
PackageManager pm = this.getPackageManager();
pm.setComponentEnabledSetting(receiver,
PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
PackageManager.DONT_KILL_APP);
}
Below is my receiver class (BootReceiver.java)
public class BootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
Intent service = new Intent(context, MyService.class);
PendingIntent pendingIntent = PendingIntent.getService(null, 0, service, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
10 * 1000, 10 * 1000,
pendingIntent);
}
}
}
My service contains a thread which checks for multiple scenarios and builds a notification for each scenario. Here's a sample below:
public int onStartCommand(Intent intent, int flags, int startId) {
notification = new NotificationCompat.Builder(this);
notification.setAutoCancel(true);
Runnable r = new Runnable() {
#Override
public void run() {
try {
boolean diff = true;
if (diff) {
// Build the notification
notification.setSmallIcon(R.drawable.icon);
notification.setTicker(getString(R.string.notification_ticker));
notification.setWhen(System.currentTimeMillis());
notification.setContentTitle(getString(R.string.notification_title));
notification.setContentText(getString(R.string.notification_1_text));
notification.setSound(alarmSound);
Intent i = new Intent(context, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setContentIntent(pendingIntent);
// Builds a notification and issues it
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Random r = new Random();
int rand = r.nextInt(1000);
nm.notify(rand, notification.build());
}
catch (Exception e) {
e.printStackTrace();
}
}
};
Thread stephThread = new Thread(r);
stephThread.start();
return START_STICKY;
}
And finally below is my AndroidManifest.xml code
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.motherslove.stephnoutsa.myapplication18calendartest"

Please can someone tell me what I've done wrong?
Thanks to help from #MikeM I could fix the problem.
Instead of
PendingIntent pendingIntent = PendingIntent.getService(null, 0, service, 0);
I had to pass in the context as the first argument, in the receiver, as shown below
PendingIntent pendingIntent = PendingIntent.getService(context, 0, service, 0);
