Android - start AlarmManager after reboot - java

AlarmManeger doesn't start after reboot but it should.
How can I do it?
AndroidManifest:
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver android:name=".AlarmEngine.AlarmManagerHelper" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
</intent-filter>
</receiver>
BroadcastReceiver:
#Override
public void onReceive(Context context, Intent intent)
{
setAlarms(context);
}
public static void setAlarms(Context context)
{
cancelAlarms(context);
AlarmDBHelper dbHelper = new AlarmDBHelper(context);
List<AlarmModel> alarms = dbHelper.getAlarms();
for (AlarmModel alarm : alarms)
{
PendingIntent pIntent = createPendingIntent(context, alarm);
...
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pIntent);

I fixed it moved app to the phone's memory.
I replace this:
android:installLocation="preferExternal" >
On this:
android:installLocation="internalOnly" >

Android notification does not work when restarting after creating notification

As long as I don't turn the phone off (even if the application is closed), the forward notification that I have created with the alarm manager in my android-java mobile application does not have a problem. But when I restart the phone before the notification time comes, it doesn't work even if it's time for my notification. Can you please help? Thanks.

I added the following permissions to my manifest file but it didn't work

<receiver android:name=".MyReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</receiver>
This is the expected behavior. If you turn off your device, all alarms are deleted. So, to workaround this issue, you must register for boot complete broadcast and re-schedule your alarm.
You can find more details on how to do it in the following question/answer:
does Alarm Manager persist even after reboot?
I think you can try use work manager, which will be executed by system.
WorkManager is the recommended solution for persistent work. Work is persistent when it remains scheduled through app restarts and system reboots. Because most background processing is best accomplished through persistent work, WorkManager is the primary recommended API for background processing.

BroadcastReceiver not working in the background OREO+

In my application there are two receivers, one receives calls (MyReceiverCall) and the second SMS (MyReceiverSms).
When you start the app everything works fine, I get a notification when I receive an SMS or call.
But if I close the app in task Manager then nothing wants to work and all incoming SMS and calls are ignored by the receiver.
I had assumptions that can be simply service with my notification does not start, but through logs I understood that the receiver simply does not work. (But so far the assumption is that services are to blame)
My code
MyReceiverCall.class
public class MyReceiverCall extends BroadcastReceiver {
private static final String ACTION = "android.intent.action.PHONE_STATE";
#Override
public void onReceive(Context context, Intent intent) {
Log.i("123","sakuraso13 ReceiverCall");
if (intent != null && intent.getAction() != null) {
if (intent.getAction().equals(ACTION)) {
String number=intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING) & number!=null) {
// some operation with number phone
Intent intentService = new Intent(context, ServiceMain.class);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
context.startForegroundService(intentService);
}else {
context.startService(intentService);
}
}
}
}
}
}
MyReceiverSms.class
public class MyReceiverSms extends BroadcastReceiver {
private static final String TAG="MyReceiverSms";
private static final String ACTION="android.provider.Telephony.SMS_RECEIVED";
#Override
public void onReceive(Context context, Intent intent) {
Log.i("123","sakuraso13 ReceiverWorking");
if(intent != null && intent.getAction()!=null) {
if (intent.getAction().equals(ACTION)) {
// some operation with number phone
Intent intentService=new Intent(context, ServiceMain.class);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
context.startForegroundService(intentService);
}else {
context.startService(intentService);
}
}
}
}
}

Sometimes in logs I can see similar when calling when the application is closed:
2019-11-19 21:57:10.978 1271-1289/? W/BroadcastQueue: Permission Denial: receiving Intent { act=android.intent.action.PHONE_STATE flg=0x1000010 (has extras) } to app.service.detector/detector.sakuraso13.Broadcaster.MyReceiverCall requires android.permission.READ_PRIVILEGED_PHONE_STATE due to sender android (uid 1000)

BroadcastReceiver does not work

I'm trying to create some simple BroadcastReceiver according to manuals but I can't to make it work.
I'm calling procedure setAlarm in onCreate function in MainActivity that looks like this:
private void setAlarm() {
Intent intent = new Intent(MainActivity.this, AlarmReceiver.class);
AlarmManager manager = (AlarmManager) getSystemService(ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, 0);
manager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+1000, pendingIntent);
}
It should activate AlarmReceiver that should do some action but doesn't do anything. It looks like this:
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "I'm running", Toast.LENGTH_LONG).show();
notifikace(context);
}
public void notifikace(Context context) {
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
mBuilder.setSmallIcon(R.drawable.notifikace);
mBuilder.setContentTitle("Notification Alert, Click Me!");
mBuilder.setContentText("aaa");
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
mNotificationManager.notify(2, mBuilder.build());
}
}
I suspect that I'm missing something in AndroidManifest but I don't know what. AndroidManifest looks like this:
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".Nastaveni"
android:label="#string/title_activity_nastaveni"
android:theme="#style/AppTheme.NoActionBar" />
<meta-data

<activity
android:name=".Tyden"
android:label="#string/title_activity_tyden"
android:theme="#style/AppTheme.NoActionBar"></activity>
<receiver android:name=".AlarmReceiver" >
</receiver>
</application>
Ultimately appliacation should be able to send notification every day at certain time even if application isn't running at the moment. (I will have to then replace
manager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+1000, pendingIntent);
line with setRepeating function but so far for testing purposes I need first to get it running.)
But so far AlarmReceiver class doesn't do anything. I'm getting some error when I try to run it (but application doesn't crash):
04-14 11:52:54.592 1300-1354/? I/ActivityManager: START u0 {act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=com.example.xxx.myapplication3/com.example.xxx.myapplication.MainActivity (has extras)} from uid 10014 on display 0

I'm not sure whether the error log is related to this or something else in the project. What am I doing wrong? Thanks in advance for any answer.
Sorry I saw later your receiver in manifest, your error is that you ar getting a pending intent with getService instead of getBroadcast.
Just change it to:
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
I tried it just now :)
-- edited I will leave this as a reference --
You have to register the receiver somehow, either by code or by xml.
The alarm is an Intent broadcast that goes to a broadcast receiver that you registered with registerReceiver(BroadcastReceiver, IntentFilter) or through the tag in an AndroidManifest.xml file.
Refer to:
-Pending intent - getBroadcast
-AlarmManager
-Triggering alarm and issues

GCM message successfully sent but the smartphone android not received

I solved it but I no longer have the source code..sorry
I don't receive the notifications on my Android device. The messagge was sent successfully to the GCM servers. I tried them all. Can someone help me? This is the code:
GCMIntentService.java
public class GCMIntentService extends IntentService {
static SharedPreferences prefs;
static Editor editor;
Context context;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
public static final String TAG = "GCM Intent Service";
public static final int NOTIFICATION_ID = 1;
public GCMIntentService() {
super(Configuration.SENDER_ID);
}
#Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
String msg = intent.getStringExtra("message");
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty()) {
if (GoogleCloudMessaging.
MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
sendNotification("Send error: " + extras.toString());
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_DELETED.equals(messageType)) {
sendNotification("Deleted messages on server: " +
extras.toString());
// If it's a regular GCM message, do some work.
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_MESSAGE.equals(messageType)) {
// This loop represents the service doing some work.
for (int i=0; i<5; i++) {
Log.i(TAG, "Working... " + (i+1)

onReceive never getting called

Below is my Java code and my XML code. Can someone please tell me why my onReceieve method is never getting called.
Java:
public class PopUPSMS extends Activity {
String RECEIVE_SMS = "RECEIVE_SMS";
private static final String LOG_TAG = "PopUPSMS";
static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.i(LOG_TAG, "onCreate");
registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.i(LOG_TAG, "onReceive");
}
}, new IntentFilter(RECEIVE_SMS));
}
}
XML:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.smith.johnathan.phone"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon" android:label="#string/app_name">

</manifest>
registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.i(LOG_TAG, "onReceive");
}
}, new IntentFilter(RECEIVE_SMS));
You have registered your broadcast receiver with the string "RECEIVE_SMS". The IntentFilter should be of a form of an action. With your declaration:
static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
you will have:
registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.i(LOG_TAG, "onReceive");
}
}, new IntentFilter(ACTION));
You can have a look at the Api demos Manifest for the XML declaration
You can't use receiver as an inner class. Create a separate one.
Don't you need to specify that you want to receive SMS in your manifest?
<application android:icon="#drawable/icon" android:label="#string/app_name">
<receiver android:name=".MyApp">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
