This is my first time trying to make an app that starts on boot and runs in the background, and I'm finding all the possible ways of doing it a little confusing. I need the app to do a quick check of a few things every half hour, and sleep in between, so I settled for using AlarmManager and setRepeating.
In this test I've set it up so a boot receiver sets the alarm, which should run a service every 60 seconds (actual app will be 30+ mins between running this). The service triggers a notification, but when I reboot the phone, the notification only shows up once. I clear it and never see it again.
I'll post the relevant code below. Can anyone tell me where I'm going wrong? Thanks!
AlarmStarter.java
public class AlarmStarter extends BroadcastReceiver {
private static final int PERIOD = 60000;
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
scheduleAlarms(context);
}
}
static void scheduleAlarms(Context ctxt) {
AlarmManager mgr = (AlarmManager) ctxt.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(ctxt, BackService.class);
PendingIntent pi = PendingIntent.getService(ctxt, 0, i, 0);
mgr.setRepeating(AlarmManager.ELAPSED_REALTIME,
SystemClock.elapsedRealtime() + PERIOD, PERIOD, pi);
}
BackService.java
public class BackService extends Service {
public BackService() {
//showNotification("ticker test", "title test", "content test", "http://google.com");
Log.d("CF", "Starting BackService");
showNotification("ticker test", "title test", "content test", "http://google.com");
}
#Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
#Override
public void onCreate() {
// Code to execute when the service is first created
}
public void showNotification(String ticker, String title, String content, String url) {
Intent notificationIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
PendingIntent pi = PendingIntent.getActivity(this, 0, notificationIntent, 0);
Notification notification = new NotificationCompat.Builder(this).setTicker(ticker)
.setSmallIcon(android.R.drawable.ic_menu_report_image)
.setContentTitle(title)
.setContentText(content)
.setContentIntent(pi)
.setAutoCancel(true)
.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);
}
}

The problem I had here was that the BackService class I was trying to trigger with the alarm, was extending from the Service class. It should have extended from the BroadcastReceiver class, as only BroadcastReceivers can be triggered by the externally sent alarms.

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 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.

I have an application that starts an Intent after the boot that works from Android 6 to Android 9 API level 28.
But this code does not work on Android 10 API level 29, Broadcast simply does not receive any events and does not run onReceive on MyClassBroadcastReceiver after the boot. Is there any extra permission on Android 10 or configuration that needs to be done?
Dry part of the example: Manifest:
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.softniels.autostartonboot">
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:name="com.softniels.autostartonboot.ForegroundService"
android:label="My Service">
<intent-filter>
<action android:name="com.softniels.autostartonboot.ForegroundService" />
</intent-filter>
</service>
<receiver
android:name=".StartMyServiceAtBootReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
</application>
Here the part that doesn't run on Android 10.
public class StartMyServiceAtBootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
Log.i("onReceive", "call onReceive ACTION_BOOT_COMPLETED");
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
}
I know that this may be old but I have faced the same problem and according to this:
https://developer.android.com/guide/components/activities/background-starts
The easiest solution I came up with was simply adding
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
And setting up the receiver:
<receiver
android:name=".BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
To the manifest.
Receiver code:
#Override
public void onReceive(Context context, Intent intent) {
if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
// Intent n = context.getPackageManager().getLaunchIntentForPackage(context.getPackageName());
// n.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
// Intent.FLAG_ACTIVITY_CLEAR_TASK);
// context.startActivity(n);
Intent myIntent = new Intent(context, MainActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(myIntent);
}
}
Both options work. The only downside I see is that it takes rather a while for app to load (can be up to 10 seconds from my testings)
Leaving this here for other people if they encounter this as well.
This only applies to android 10 and up. There is a need to request "Display over other apps" permission
This requires drawing overlay, which can be done with:
if (!Settings.canDrawOverlays(getApplicationContext())) {
Intent myIntent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
Uri uri = Uri.fromParts("package", getPackageName(), null);
myIntent.setData(uri);
startActivityForResult(myIntent, REQUEST_OVERLAY_PERMISSIONS);
return;
}
Guess I found a 'solution' for me.
public class StartMyServiceAtBootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.P) {
Log.e(TAG, "launching from special > API 28 (" + Build.VERSION.SDK_INT + ")"); // You have to schedule a Service
JobServiceScheduler jobServiceScheduler = new JobServiceScheduler(context);
boolean result = jobServiceScheduler.scheduleMainService(20L); // Time you will wait to launch
} else {
Log.e(TAG, "launching from normal < API 29"); // You can still launch an Activity
try {
Intent intentMain = new Intent(context, YourActivity.class);
intentMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
if (Build.VERSION.SDK_INT < 28) {
context.startService(intentMain);
} else {
context.startForegroundService(intentMain);
}
} catch (ActivityNotFoundException ex) {
Log.e(TAG, "ActivityNotFoundException" + ex.getLocalizedMessage());
}
}
}
boolean scheduleMainService(Long segundos) {
ComponentName serviceComponent = new ComponentName(context, YourService.class);
JobInfo.Builder builder = getCommonBuilder(serviceComponent, YOUR_SERVICE_JOB_ID);
builder.setMinimumLatency(TimeUnit.SECONDS.toMillis(segundos / 2)); // wait at least
builder.setOverrideDeadline(TimeUnit.SECONDS.toMillis(segundos)); // maximum delay
PersistableBundle extras = new PersistableBundle();
extras.putLong("time", segundos);
builder.setExtras(extras);
JobScheduler jobScheduler = getJobScheduler(context);
if (jobScheduler != null) {
jobScheduler.schedule(builder.build());
return true;
} else {
return false;
}
}
context.startActivity() is not launching, I solved it the following way:
private void restartApp( Context mContext) {
try {
long restartTime = 1000*5;
Intent intents = mContext.getPackageManager().getLaunchIntentForPackage(mContext.getPackageName());
PendingIntent restartIntent = PendingIntent.getActivity(mContext, 0, intents, PendingIntent.FLAG_ONE_SHOT);
AlarmManager mgr = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
mgr.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + restartTime, restartIntent);
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
mgr.setExact(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + restartTime, restartIntent);
}
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
}
I solved it with this permission in the manifest:
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
And in the main activity :
if (!Settings.canDrawOverlays(getApplicationContext())) {
startActivity(Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION));
}
The correct import for Settings is:android.provider
The first time the app boots the permission will be prompted for controlling which apps can draw on top of other apps, the next device will start the application will boot up using the typical broadcast receiver.
Here is the doc
I'm going to build an Application with Alarm feature to remind the patients to take medicine on time.
But current issue is the alarm manager didn't trigger on the XiaoMi phone, and it work on the samsung note 4 in Android 6.0. And before implement the code to my project, I had create a new project and using the same code to test it. In the new project the code work perfectly as long as the Autostart permission has grant. The alarm will trigger on time, and even restart the phone, the boot receiver will also work recreate the alarm, but it only didn't work on my application.
And now below is my code.
OnAlarmReceiver.java
public class OnAlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("MyApp", "Received wake up from alarm manager.");
long rowid = intent.getExtras().getLong(RemindersDbAdapter.KEY_ROWID);
WakeReminderIntentService.acquireStaticLock(context);
Intent i = new Intent(context, ReminderService.class);
i.putExtra(RemindersDbAdapter.KEY_ROWID, rowid);
context.startService(i);
}
}
ReminderManager.java
public class ReminderManager {
private Context mContext;
private AlarmManager mAlarmManager;
public ReminderManager(Context context) {
mContext = context;
mAlarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
}
public void setReminder(Long taskId, Calendar when) {
Intent i = new Intent(mContext, OnAlarmReceiver.class);
i.putExtra(RemindersDbAdapter.KEY_ROWID, (long)taskId);
int broadcastID = Integer.parseInt(taskId+""+when.getTime().getDate()+""+when.getTime().getYear()+""+taskId);
broadcastID = (int)when.getTimeInMillis();
System.out.println("Alarm when : "+ when.getTimeInMillis());
PendingIntent pi = PendingIntent.getBroadcast(mContext, broadcastID, i, PendingIntent.FLAG_ONE_SHOT);
System.out.println("Alarm Set ID : "+broadcastID);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
mAlarmManager = (AlarmManager)mContext.getSystemService(Context.ALARM_SERVICE);
AlarmManager.AlarmClockInfo ac= new AlarmManager.AlarmClockInfo(when.getTimeInMillis(), pi);
mAlarmManager.setAlarmClock(ac, pi);
System.out.println("Android 6.0 Marshmallow and above.");
}else if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
mAlarmManager.setExact(AlarmManager.RTC_WAKEUP, when.getTimeInMillis(), pi);
System.out.println("Android 4.4 Kikkat and above.");
}else{
mAlarmManager.set(AlarmManager.RTC_WAKEUP, when.getTimeInMillis(), pi);
System.out.println("Android 4.3 Jelly Bean and below.");
}
}
}
Manifest file:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
Forgot to mention, i had already register the .OnAlarmReceiver in manifest file
<receiver android:name=".OnBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<receiver android:name=".OnAlarmReceiver" />
My main issue is with same code it work on the new project i had create to do testing, but didn't work on the my main project.
Can someone help me out. Thanks in advance.
Register OnAlarmReceiver in manifest
<receiver android:name=".OnAlarmReceiver" />

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);
