Trying to start a service on boot on Android

I've been trying to start a service when a device boots up on android, but I cannot get it to work. I've looked at a number of links online but none of the code works. Am I forgetting something?

AndroidManifest.xml

<receiver
    android:name=".StartServiceAtBootReceiver"
    android:enabled="true"
    android:exported="false"
    android:label="StartServiceAtBootReceiver" >
    <intent-filter>
        <action android:name="android.intent.action._BOOT_COMPLETED" />
    </intent-filter>
</receiver>

<service
    android:name="com.test.RunService"
    android:enabled="true" />

BroadcastReceiver

public void onReceive(Context context, Intent intent) {
    if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
        Intent serviceLauncher = new Intent(context, RunService.class);
        context.startService(serviceLauncher);
        Log.v("TEST", "Service loaded at start");
    }
}

This is what I did

1. I made the Receiver class

public class BootReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        //whatever you want to do on boot
       Intent serviceIntent = new Intent(context, YourService.class);
       context.startService(serviceIntent);
    }
}

2.in the manifest

<manifest...>
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
    <application...>
        <receiver android:name=".BootReceiver" android:enabled="true" android:exported="false">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>
    ...

3.and after ALL you NEED to "set" the receiver in your MainActivity, it may be inside the onCreate

...
 final ComponentName onBootReceiver = new ComponentName(getApplication().getPackageName(), BootReceiver.class.getName());
        if(getPackageManager().getComponentEnabledSetting(onBootReceiver) != PackageManager.COMPONENT_ENABLED_STATE_ENABLED)
        getPackageManager().setComponentEnabledSetting(onBootReceiver,PackageManager.COMPONENT_ENABLED_STATE_ENABLED,PackageManager.DONT_KILL_APP);
...

the final steap I have learned from ApiDemos

The other answers look good, but I thought I'd wrap everything up into one complete answer.

You need the following in your AndroidManifest.xml file:

  1. In your <manifest> element:

    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

  2. In your <application> element (be sure to use a fully-qualified [or relative] class name for your BroadcastReceiver):

    <receiver android:name="com.example.MyBroadcastReceiver">  
    <intent-filter>  
        <action android:name="android.intent.action.BOOT_COMPLETED" />  
    </intent-filter>  
</receiver>

    (you don't need the android:enabled, exported, etc., attributes: the Android defaults are correct)

    In MyBroadcastReceiver.java:

    package com.example;

public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent startServiceIntent = new Intent(context, MyService.class);
        context.startService(startServiceIntent);
    }
}

From the original question:

  • it's not clear if the <receiver> element was in the <application> element
  • it's not clear if the correct fully-qualified (or relative) class name for the BroadcastReceiver was specified
  • there was a typo in the <intent-filter>

How to start service on device boot(autorun app, etc.)

For first: since version Android 3.1+ you don't receive BOOT_COMPLETE if user never started your app at least once or user "force closed" application. This was done to prevent malware automatically register service. This security hole was closed in newer versions of Android.

Solution:

Create app with activity. When user run it once app can receive BOOT_COMPLETE broadcast message.

For second: BOOT_COMPLETE is sent before external storage is mounted. If app is installed to external storage it won't receive BOOT_COMPLETE broadcast message.

In this case there is two solution:

  1. Install your app to internal storage
  2. Install another small app in internal storage. This app receives BOOT_COMPLETE and run second app on external storage.

If your app already installed in internal storage then code below can help you understand how to start service on device boot.

In Manifest.xml

Permission:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Register your BOOT_COMPLETED receiver:

<receiver android:name="org.yourapp.OnBoot">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
    </intent-filter>
</receiver>

Register your service:

<service android:name="org.yourapp.YourCoolService" />

In receiver OnBoot.java:

public class OnBoot extends BroadcastReceiver
{

    @Override
    public void onReceive(Context context, Intent intent) 
    {
        // Create Intent
        Intent serviceIntent = new Intent(context, YourCoolService.class);
        // Start service
        context.startService(serviceIntent);

    }

 }

For HTC you maybe need also add in Manifest this code if device don't catch RECEIVE_BOOT_COMPLETED:

<action android:name="android.intent.action.QUICKBOOT_POWERON" />

Receiver now look like this:

<receiver android:name="org.yourapp.OnBoot">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
        <action android:name="android.intent.action.QUICKBOOT_POWERON" />
    </intent-filter>
</receiver>

How to test BOOT_COMPLETED without restart emulator or real device? It's easy. Try this:

adb -s device-or-emulator-id shell am broadcast -a android.intent.action.BOOT_COMPLETED

How to get device id? Get list of connected devices with id's:

adb devices

adb in ADT by default you can find in:

adt-installation-dir/sdk/platform-tools

After trying all of mentioned answers and tricks, I finally find why the code is not work in my phone. Some Android phones like "Huawei Honor 3C Android 4.2.2" have a Statup Manager menu in their settings and your app must be checked in the list. :)

As @Damian commented, all the answers in this thread are doing it wrong. Doing it manually like this runs the risk of your Service being stopped in the middle from the device going to sleep. You need to obtain a wake lock first. Luckily, the Support library gives us a class to do this:

public class SimpleWakefulReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // This is the Intent to deliver to our service.
        Intent service = new Intent(context, SimpleWakefulService.class);

        // Start the service, keeping the device awake while it is launching.
        Log.i("SimpleWakefulReceiver", "Starting service @ " + SystemClock.elapsedRealtime());
        startWakefulService(context, service);
    }
}

then, in your Service, make sure to release the wake lock:

    @Override
    protected void onHandleIntent(Intent intent) {
        // At this point SimpleWakefulReceiver is still holding a wake lock
        // for us.  We can do whatever we need to here and then tell it that
        // it can release the wakelock.

...
        Log.i("SimpleWakefulReceiver", "Completed service @ " + SystemClock.elapsedRealtime());
        SimpleWakefulReceiver.completeWakefulIntent(intent);
    }

Don't forget to add the WAKE_LOCK permssion to your mainfest:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

If you're using Android Studio and you're very fond of auto-complete then I must inform you, I'm using Android Studio v 1.1.0 and I used auto-complete for the following permission

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

And Android Studio Auto-completedRECEIVE_BOOT_COMPLETED all in lower-case like receive_boot_completed and I kept pulling my hair out because I'd already ticked out my checklist for things to do to start service at boot. I just confirmed again

Android Studio DOES auto-complete this permission in lower-case.

In fact,I get into this trouble not long ago,and it's really really easy to fix,you actually do nothing wrong if you setup the "android.intent.action.BOOT_COMPLETED" permission and intent-filter.

Be attention that if you On Android 4.X,you have to run the broadcast listener before you start service on boot,that means,you have to add an activity first,once your broadcast receiver running,your app should function as you expected,however,on Android 4.X,I haven't found a way to start the service on boot without any activity,I think google did that for security reasons.

Along with

<action android:name="android.intent.action.BOOT_COMPLETED" />

also use,

<action android:name="android.intent.action.QUICKBOOT_POWERON" />

HTC devices dont seem to catch BOOT_COMPLETED

I found out just now that it might be because of Fast Boot option in Settings > Power

When I have this option off, my application receives a this broadcast but not otherwise.

By the way, I have Android 2.3.3 on HTC Incredible S.

Hope it helps.

note that at the beginning of the question, there is a typo mistake:

<action android:name="android.intent.action._BOOT_COMPLETED"/>

instead of :

<action android:name="android.intent.action.BOOT_COMPLETED"/>

one small "_" and all this trouble :)

As an additional info: BOOT_COMPLETE is sent to applications before external storage is mounted. So if application is installed to external storage it won't receive BOOT_COMPLETE broadcast message.

More details here in section Broadcast Receivers listening for "boot completed"

I think your manifest needs to add: 

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

I have an additional <category>-tag, don't know if that makes any difference.

<receiver android:name="BootIntentReceiver">  
        <intent-filter>  
            <action android:name="android.intent.action.BOOT_COMPLETED" />  
            <category android:name="android.intent.category.HOME" />  
        </intent-filter>  
</receiver>

Have you tried ommiting the if-clause "android.intent.action.BOOT_COMPLETED".equals(intent.getAction(), as the receiver probably only receives that intent anyway?
