I am trying to create a Service application without a UI/Activity.
The service will start on BOOT_COMPLETED. Currently I am experiencing an issue when the receiver service cannot start the main service.
The error sound like that (Android Device Monitor):
Tag: Activity Manager
Text: Unable to start service Intent { cmp=com.remote.cat/.ActionService } U=0: not found
My android OS version on the device is 4.2.2
I am testing it via this command in PowerShell:
adb.exe shell am broadcast -a android.intent.action.BOOT_COMPLETED -n com.remote.cat/.AutoStartServiceReceiver
Both services are in the root of the package com.remote.cat
Feel like I am missing a small thing or having a typo, would greatly appreciate any help!
Thank you!
Here is the code of the manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.remote.cat"
android:installLocation="internalOnly">
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application android:allowBackup="true" android:label="#string/app_name"
android:icon="#mipmap/ic_launcher" android:theme="#style/AppTheme">
<receiver android:name="com.remote.cat.AutoStartServiceReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
<service android:name="com.remote.cat.AutoStartServiceReceiver"></service>
<service android:name="com.remote.cat.ActionService"></service>
</manifest>
Here is the brodcastreceiver class:
package com.remote.cat;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class AutoStartServiceReceiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED))
{
Intent serviceIntent = new Intent(context, ActionService.class);
//Intent serviceIntent = new Intent("com.remote.cat.ActionService");
context.startService(serviceIntent);
}
}
}
Here is the main service that I am trying to start:
package com.remote.cat;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
import java.util.TimerTask;
import java.util.concurrent.ScheduledFuture;
import java.util.concurrent.ScheduledThreadPoolExecutor;
import java.util.concurrent.TimeUnit;
public class ActionService extends Service
{
private ScheduledThreadPoolExecutor executor = null;
#Override
public IBinder onBind(Intent intent)
{
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
executor = new ScheduledThreadPoolExecutor(4);
final ScheduledFuture<?> handle = executor.scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), "one minute message", Toast.LENGTH_LONG).show();
}
}, 0, 8, TimeUnit.SECONDS);
return START_STICKY;
}
}
Change your AutoStartServiceReceiver declaration in the manifest to be a <receiver> rather than <service>.
The error is in your broadcastreceiver class
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED))
it should be
if(intent.getAction().equals("android.intent.action.BOOT_COMPLETED"))
EDIT
I believe you have to declare your services inside the application tag since it is a part of the application

I am working on an android application that listens to Boot Complete Broadcast and performs some processes.
This broadcast works on my Moto G5 and simulator, however, on Oneplus the application never receives it.
Create a BroadCastReciver class like this :
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class RebootService extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context,"Service is running", Toast.LENGTH_LONG).show();
}
}
Define your service in AndroidManifest.
<receiver android:name=".RebootService">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
And finally :
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
I want to create an Android application which performs some action periodically (every minute) in the background. The application shall have no user interface, therefore there will be no Action-Class. It shall start automatially after boot.
I have coded my Application as shown below, but it just does not start after boot? Can anyone help?
I am using a Samsung Tablet GT-P5200 with Android 4.4.2
Many thanks for your help in advance.

The application shall have no user interface, therefore there will be no Action-Class.
Newly-installed apps' manifest-registered receivers are disabled until something uses an explicit Intent to start one of your components. Usually, this is the user tapping on the icon for one of your activities in a home screen's launcher. And usually that is not a problem, because all apps need an activity, to allow the user to configure the behavior of the app, get help, read the license agreement terms, etc.
In some scenarios, something other than a home screen launcher icon can start up one of your components with an explicit Intent. For example, if you are a plugin to some other app, that other app might detect your installation and start up one of your components.
But, if nothing will start one of your components with an explicit Intent, then your BOOT_COMPLETED receiver will never get control, even after a reboot.
I have stuck with an issue of running a service when force stop is clicked and when i restart my mobile the service should be invoked.I have followed some examples but i cant able to achieve the task.Can any one guide me to achieve the task.
Required:
1.Service should run when force stop has been clicked from settings
2.Service should run when mobile has been restarted.

In theory, this is not possible; according to the Android security model.
As Panaj Kumar points out in the comments:
When user does force stop, means he does not want to run this
application (any component). he is not interested anymore, and this
is rights of user. SO android does not gives a way to keep running
your service, even after forced close your app.
Android will prevent the app from restarting using the START_STICKY flag, and will disable the RECEIVE_BOOT_COMPLETED receiver. The system will also disable all Alarms that have been set for this app.
Before the system will allow the app to run again, the user must run an Activity of the app themselves.
That said, it seems that certain apps are still able to break the rules in this way. This should be considered incorrect and would be taking advantage of a security hole, however it shows that it is still possible, even on KitKat.
The Discovery Insure driving app seems to be able to restart itself when it has been force stopped, and will restart on boot:
Discovery Insure Driving Challenge on Play Store
However, this functionality should not be relied on - hopefully this security flaw will be fixed in future system updates.
Write this on in your OnCreate of the main launching activity
if(!isMyServiceRunning(ServiceClass.class))
context.startService(new Intent(context.getApplicationContext(),ServiceClass.class));
here is the running service check function
private boolean isMyServiceRunning(Class<?> serviceClass) {
ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
if (serviceClass.getName().equals(service.service.getClassName())) {
return true;
}
}
return false;
}
and Create your service with this architecture.Observe the return START_STICKY
public class ServiceClass extends IntentService {
public ServiceClass()
{
super("null");
}
public Context context;
public Intent intent;
public Date currentTime;
#Override
public int onStartCommand(#Nullable Intent intent, int flags, int startId) {
onHandleIntent(intent);
return START_STICKY;
}
#Override
protected void onHandleIntent(#Nullable Intent intnt) {
currentTime = Calendar.getInstance().getTime();
context = getApplicationContext();
this.intent = intnt;
Log.d("ServiceClass","Service class running "+ currentTime);
}
}
I take below sample in net searching. I implemented the sample with some modification, but it shows error after rebooting the phone. I also pasting source code i used in the sample, please help me to solve problem

I dont think you need to compare the intent..
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
.....
}
as, it is captured in the xml file that BootCompletedIntentReceiver should be executed for BOOT_COMPLETED intent.

floow these steps for stating your service on BOOT:
Step 1: In AndroidManifest.xml add BOOT_COMPLETED permission as:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
Step 2: In AndroidManifest.xml Register your Reciver as:
<receiver android:name=".StartActivityAtBoot" android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</receiver>
Step 3: In AndroidManifest.xml Register your Service as:
<service android:name=".CompareIMSI"> </service>
Step 3: In StartActivityAtBoot Start your service as:
public class StartActivityAtBoot extends BroadcastReceiver
{
static final String ACTION = "android.intent.action.BOOT_COMPLETED";
public void onReceive(Context context, Intent intent)
{
if (intent.getAction().equals(ACTION))
{
context.startService(new Intent(context,
CompareIMSI.class), null);
Toast.makeText(context, "CompareIMSI service has started!", Toast.LENGTH_LONG).show();
}
}
}
This is all about Starting a Service on Boot.Thanks
You need to register the BroadcastReceiver in the Android manifest, like this:
<receiver android:name=".StartActivityAtBoot">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Also make sure that you have this permission in the manifest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Check Your androidManifest file. You need to add receiver at androidManifest file.
<receiver android:name=".......StartActivityAtBoot" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>
