Why can't i see logs of code pieces triggered by AlarmManager? - android-studio

Question

I'm very new to android studio development so the answer is probably trivial.
That being said, I've busted my head around the problem for a day now :/
I am trying to run a chunk of code every 10 seconds even when the app is closed using AlarmManager.
I copy-pasted what is suggested in this guide https://guides.codepath.com/android/Starting-Background-Services
I'm a little puzzled by the result -
I think I do get alarm triggered every 10 seconds, as indicated in the log:
04-20 21:25:44.125 557-632/? D/AlarmManager: Triggered Alarm 22ad4130
RTC_WAKEUP IntentSender{220fb650: PendingIntentRecord{2243b570
com.example.somelocation.myapplication broadcastIntent}} 04-20
21:25:44.125 557-557/? V/AlarmManager: triggered: flg=0x14
cmp=com.example.somelocation.myapplication/.MyAlarmReceiver
But i can't see any of my custom logs positioned inside my BroadcastReceiver or my IntentService.
MyTestService:
package com.example.somelocation.myapplication;
import android.app.IntentService;
import android.content.Intent;
import android.util.Log;
public class MyTestService extends IntentService {
public MyTestService() {
super("MyTestService");
}
#Override
protected void onHandleIntent(Intent intent) {
// Do the task here
Log.i("MyTestService", "Service running"); // Can't see this log
}
}
MyAlarmReceiver:
package com.example.somelocation.myapplication;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class MyAlarmReceiver extends BroadcastReceiver {
public static final int REQUEST_CODE = 12345;
#Override
public void onReceive(Context context, Intent intent) {
Log.e("MyTestService","broadcastreciever onReceive called"); // Can't see this log
Intent i = new Intent(context, MyTestService.class);
i.putExtra("foo", "bar");
context.startService(i);
}
}
Main Activity:
package com.example.somelocation.myapplication;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private TextView batteryInfo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scheduleAlarm();
}
public void scheduleAlarm() {
Intent intent = new Intent(getApplicationContext(), MyAlarmReceiver.class);
final PendingIntent pIntent = PendingIntent.getBroadcast(this, MyAlarmReceiver.REQUEST_CODE,
intent, PendingIntent.FLAG_UPDATE_CURRENT);
long firstMillis = System.currentTimeMillis();
AlarmManager alarm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
alarm.setInexactRepeating(AlarmManager.RTC_WAKEUP, firstMillis,
10000, pIntent);
}
}
my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.somelocation.myapplication">
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<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>
<receiver
android:name=".MyAlarmReceiver"
android:process=":remote" >
</receiver>
<service
android:name=".MyTestService"
android:exported="false"/>
</activity>
</application>
</manifest>
What am I missing?
update:
Got it! It was an error in my manifest file:
The close tag of the main activity was after the receiver declaration. should be:
<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>
<receiver
android:name=".MyAlarmReceiver"
android:process=":remote" >
</receiver>
<receiver
android:name=".BootReceiver"
android:enabled="true"
android:exported="true"/>
</application>

The log is being printed on the console... here is the log I am getting
04-22 18:30:28.421 1830-4146/com.example.somelocation.myapplication I/MyTestService: Service running
04-22 18:30:45.337 2641-2641/com.example.somelocation.myapplication:remote E/MyTestService: broadcastreciever onReceive called
04-22 18:30:45.344 1830-4394/com.example.somelocation.myapplication I/MyTestService: Service running
04-22 18:30:48.4032641-2641/com.example.somelocation.myapplication:remote E/MyTestService: broadcastreciever onReceive called
You are creating a separate process('remote') for the BroadcastReceiver and your logcat may be setup to display only the main process create at first.
See the screenshots -
So change the application process from the dropdown and also select the log level to Verbose.
