In my App, I'm using AlarmManager for transmitting keep-alive every day once a day.
I'm using the following code for starting athe AlaramManager
Calendar calendar = DateUtils
.getNextKeepAliveTime(keepAliveHours, keepAliveMinutes);
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(),
ALARM_REQUEST_CODE, intent, 0); // PendingIntent.FLAG_UPDATE_CURRENT);
// Get the AlarmManager service
Log.d(TAG, "cal: " + calendar.toString());
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
long diff = calendar.getTimeInMillis() - System.currentTimeMillis();
if(diff < 0) diff = AlarmManager.INTERVAL_FIFTEEN_MINUTES;
am.setInexactRepeating(AlarmManager.RTC_WAKEUP, diff, AlarmManager.INTERVAL_DAY, sender);
When activity goes background, the receiver, AlarmReceiver, does not get any event. But it working successfully when activity in foreground.
Ther receiver declaration in my manifest is -
<receiver android:name="MainActivity$AlarmReceiver" android:enabled="true" />
The manifest is
<?xml version="1.0" encoding="utf-8"?>
<uses-sdk
android:minSdkVersion="8"

The receiver code is
public static class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d(TAG, intent.getExtras().toString());
if (!inForeground) {
Log.d(TAG, "*** Move app to front!");
Intent it = new Intent("intent.my.action");
it.setComponent(new ComponentName(context.getPackageName(),
MainActivity.class.getName()));
it.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_CLEAR_TOP);
context.getApplicationContext().startActivity(it);
}
try {
Toast.makeText(context, "alarm message", Toast.LENGTH_SHORT).show();
MainActivity.instance.sendKeepALive();
} catch (Exception e) {
Toast.makeText(
context,
"There was an error somewhere, but we still received an alarm",
Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
}
How it can be solved?
Thanks,
Eyal.
Try to remove the code for the broadcast receiver from the Activity ,make another java file and put it there and also modify your manifest as per that
<receiver android:name=".AlarmReceiver" />
instead of
<receiver android:name="MainActivity$AlarmReceiver" android:enabled="true" />

I have followed below example code for implementing Periodic background service. Periodic task executes correctly If app on foreground on 1st time. If, I close application then Background service is not working.
https://github.com/codepath/android_guides/wiki/Starting-Background-Services#using-with-alarmmanager-for-periodic-tasks
1) BroadcastReceiver service for Bootcomplete
public class BootBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// Launch the specified service when this message is received
Intent startServiceIntent = new Intent(context, MyTestService.class);
context.startService(startServiceIntent);
}
}
2) BroadcastReceiver to start service
public class MyAlarmReceiver extends BroadcastReceiver {
public static final int REQUEST_CODE = 12345;
// Triggered by the Alarm periodically (starts the service to run task)
#Override
public void onReceive(Context context, Intent intent) {
Intent i = new Intent(context, MyTestService.class);
i.putExtra("foo", "bar");
context.startService(i);
Toast.makeText(context, "Welcome --------1", Toast.LENGTH_LONG).show();
}
}
3) IntenetService class: To execute my background task
public class MyTestService extends IntentService {
// Must create a default constructor
public MyTestService() {
// Used to name the worker thread, important only for debugging.
super("test-service");
}
#Override
public void onCreate() {
super.onCreate(); // if you override onCreate(), make sure to call super().
}
#Override
protected void onHandleIntent(Intent intent) {
}
}
4) Service is started from activity as
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scheduleAlarm();
}
// Setup a recurring alarm every half hour
public void scheduleAlarm() {
// Construct an intent that will execute the AlarmReceiver
Intent intent = new Intent(getApplicationContext(), MyAlarmReceiver.class);
// Create a PendingIntent to be triggered when the alarm goes off
final PendingIntent pIntent = PendingIntent.getBroadcast(this, MyAlarmReceiver.REQUEST_CODE,
intent, PendingIntent.FLAG_UPDATE_CURRENT);
// Setup periodic alarm every 5 seconds
long firstMillis = System.currentTimeMillis(); // alarm is set right away
AlarmManager alarm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
// First parameter is the type: ELAPSED_REALTIME, ELAPSED_REALTIME_WAKEUP, RTC_WAKEUP
// Interval can be INTERVAL_FIFTEEN_MINUTES, INTERVAL_HALF_HOUR, INTERVAL_HOUR, INTERVAL_DAY
alarm.setRepeating(AlarmManager.RTC_WAKEUP, firstMillis,
30000, pIntent);
}
}

If, implement above as sample project as separate then, background service is executing fine always. But If try to integrate with my existing code then not working...
Edited: Found Solution
It got resolved by adding full path android:name service in AndroidManifest.xml
<service
android:name="test.org.help.syncmanager.auto.MyTestService"

I'm trying to call my AlarmReceiver which extends BroadcastReceiver. After I run this code, i can't see any of logs. Could you please help me in this issue. :D
Here's where I try to call AlarmReceiber
public void downloadTweets(Context context) {
ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
if (networkInfo != null && networkInfo.isConnected()) {
Intent alarmIntent = new Intent(context,AppService.AlarmReceiver.class);
alarmIntent.putExtra(AppService.SCREEN_NAME, ScreenName);
PendingIntent pi = PendingIntent.getBroadcast(context,0,alarmIntent,PendingIntent.FLAG_UPDATE_CURRENT);//getBroadcast(context, 0, i, 0);
AlarmManager am=(AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Log.v(LOG_TAG, "shot");
am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 1, pi);
Log.v(LOG_TAG, "shot finish");
} else {
Log.v(LOG_TAG, "No network connection available.");
}
}
and here's my AlarmReceiver class which is a sub-class of AppService
public static class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.v(LOG_TAG, "AlarmReceiver");
Intent sendIntent = new Intent(context,AppService.class);
sendIntent.putExtra(AppService.SCREEN_NAME,intent.getStringExtra(AppService.SCREEN_NAME));
context.startService(sendIntent);
Log.v(LOG_TAG, "AlarmReceiver done");
}
}
And my manifest has this...
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >

android:label="#string/app_name" >

</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<service android:name=".service.AppService"/>
<receiver android:name=".service.AppService$AlarmReceiver" android:enabled="true"/>
When I run, the log shows only shot and shot finish
Could you please help me solve this issue.
Add:
sendIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
in your AlarmReceiver class
Change your manifest file to:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >

I tried it with 2 receivers: none of them working.
Here one of the receivers that should write a logfile to SD, which is working fine from the Launcher Activity:
public class MyBroadcastReceiver extends BroadcastReceiver {
// Restart service every 30 seconds
private static final long REPEAT_TIME = 1000 * 10;
#Override
public void onReceive(Context context, Intent intent) {
Log.e("MyBroadcastReceiver", "BroadcastReceiver");
appendLog("MyBroadcastReceiver BroadcastReceiver \n");
AlarmManager service = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, UpdateService.class);
PendingIntent pending = PendingIntent.getBroadcast(context, 0, i,
PendingIntent.FLAG_CANCEL_CURRENT);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 30);
service.setInexactRepeating(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), REPEAT_TIME, pending);
Log.wtf("MyBroadcastReceiver", "Alarm went off");
}
public static void appendLog(String text) {
File logFile = new File("sdcard/logfile.txt");
if (!logFile.exists()) {
try {
logFile.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
try {
// BufferedWriter for performance, true to set append to file flag
BufferedWriter buf = new BufferedWriter(new FileWriter(logFile,
true));
buf.append(text);
buf.newLine();
buf.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
I cannot see the error. Anyone does?
PS the app is started once, so this: http://commonsware.com/blog/2011/07/05/boot-completed-regression.html is covered.
thanks,
It took me long the key to the problem was in the manifest.xml
here the changes to got it run (only the receiver block):
<receiver
android:name="com.example.bootService.MyBroadcastReceiver"
android:exported="true"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.PACKAGE_REPLACED" />
<data
android:path="com.example.bootService"
android:scheme="package" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
important was the
<category android:name="android.intent.category.DEFAULT" />
tag
My program is to listen receive_boot_complete broadcast when device completes the boot.
The program is working fine as expected with android 4.0.3, but the same thing is not happening when I am running the code on Android 4.4.4 device.
The broadcastreceiver is not receiving a boot completed broadcast.
Is there anything new for Android 4.4.4? Running it on Moto G.

You have to define your receiver with exported = true and enabled = true
<android:name=".BootReceiver"
android:enabled="true"
android:exported="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" />
This might be because of a bug in Android 4.4.4 r1/r2
See
Bug in Android KitKat
I've a class MyBroadcastReceiver that is registered to start at boot up. The manifest is below. I am running this via eclipse on a Android Motorola Xoom wifi only tablet - which is Android 3.2, API level 13 (from the dev.android site).
I have googled for this and tried a few things:
put android:exported="true"
used android:installLocation="internalOnly" to make sure it doesn't install on the SD card
after installing on the device, I ran the app a couple of times before testing the bootup (as some links said Android 3.x onwards won't immediately start sending boot events to the app unless user has manually initiated it at least once)
However even now the broadcast receiver doesn't seem to run when the device boots up (based on logcat).
Here is my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mypack"
android:versionCode="1"
android:versionName="1.0"

Code for broadcast receiver -

import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class MyBroadcastReceiverX extends BroadcastReceiver {
private String TAG = "Broadcast Receiver:";
AlarmManager alarm;
#Override
public void onReceive(Context arg0, Intent arg1) {
Log.i(TAG, "Entered onReceive.");
alarm = (AlarmManager) arg0.getSystemService(Context.ALARM_SERVICE);
Intent intentUploadService = new Intent (arg0, UploaderService.class);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 10);
PendingIntent pi = PendingIntent.getBroadcast(arg0, 0, intentUploadService , 0);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 5000, pi);
Log.i(TAG, "Alarm set. Exiting onReceive.");
Intent myIntent = new Intent(arg0, UploaderService.class);
arg0.startService(myIntent);
}
}
Seems to be working now.. final manifest below if it helps -
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0"
android:installLocation="internalOnly"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-sdk android:minSdkVersion="8" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".MainCamApp" android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name=".UploaderService" />
<receiver android:name=".MyBroadcastReceiverX" android:enabled="true" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED">
<category android:name="android.intent.category.DEFAULT"/>
</action>
</intent-filter>
</receiver>
</application>
</manifest>
Try the following:
<receiver android:name=".MyBroadcastReceiverX" android:enabled="true" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED">
<category android:name="android.intent.category.DEFAULT"/>
</action>
</intent-filter>
</receiver>
You also have incorrect class name specified in manifest - it should be MyBroadcastReceiverX rather then MyBroadcastReceiver
You need to write code after receiving the android.intent.action.BOOT_COMPLETED intent.
try this.
#Override
public void onReceive(Context context, Intent intent) {
Log.d("TEST", intent.getAction());
if (intent.getAction().equalsIgnoreCase(
"android.intent.action.BOOT_COMPLETED")) {
Log.i(TAG, "Entered onReceive.");
alarm = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intentUploadService = new Intent (context, UploaderService.class);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 10);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intentUploadService , 0);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 5000, pi);
Log.i(TAG, "Alarm set. Exiting onReceive.");
//no need to initialize intent twice
// Intent myIntent = new Intent(context, UploaderService.class);
context.startService(intentUploadService );
}
}
