BroadcastReceiver not receiving BOOT_COMPLETED
I've looked around here for similiar problems, but for some reason my BroadcastReceiver never ends up receiving the android.intent.action.BOOT_COMPLETED Intent.
Here is my (relative) Android.Manifest File:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
<receiver android:name=".BootReceiver"
android:enabled="true"
android:exported="true"
android:label="BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
</intent-filter>
</receiver>
And Here is the actual Receiver.
public class BootReceiver extends BroadcastReceiver {
private static final String TAG="BootReceiver";
@Override public void onReceive(Context context,Intent intent){
try{
context.startService(new Intent(context开发者_StackOverflow,ConnectivityListener.class));
Log.i(TAG,"Starting Service ConnectivityListener");
}catch(Exception e){
Log.e(TAG,e.toString());
}
}
}
Thanks! Any help is greatly appreciated
You can emulate all broadcast actions by connecting via adb to the device and open a device shell.
Here we go:
- open console/terminal and navigating to /platform-tools
- type
adb shell
or on linux/mac./adb shell
- in the shell type
am broadcast -a android.intent.action.BOOT_COMPLETED
or whatever action you want to fire
There are a bunch of nice commands coming with adb or the adb shell. Just try it

I'm posting this in the hope that it will be helpful to someone who has tried everything but still cannot get it to run on boot after installation or it used to work before and doesn't work anymore.
So assuming you have added the permission:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
And registered your receiver:
<receiver android:name="com.example.startuptest.StartUpBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
And coded your BroadcastReceiver
:
public class StartUpBootReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
Log.d("startuptest", "StartUpBootReceiver BOOT_COMPLETED");
...
}
}
}
Starting with Android 3.1 all applications, upon installation, are placed in a "stopped" state.(This is the same state that the application ends up in after the user force-stops the app from the Settings application.)
While in "stopped" state, the application will not run for any reason, except by a manual launch of an activity. (Meaning no BroadcastRecevier
(ACTION_PACKAGE_INSTALLED
, BOOT_COMPLETED
etc. will be invoked, regardless of the event for which they have registered, until the user runs the app manually.)
This is a design decision by Google to prevent malware apps. Google has advocated that users should launch an activity from the launcher first, before that application can do much. Preventing BOOT_COMPLETED
from being delivered until the activity is launched is a logical consequence of that argument.
Once a user runs any activity in your app once, you will receive the BOOT_COMPLETED broadcast after all future boots.
More details about this:

http://devmaze.wordpress.com/2011/12/05/activating-applications/
If your app installed on external storage(SD card), you will never receive Boot Complete action. So you have to specify android:installLocation="internalOnly"
in the manifest tag
.
Your <uses-permission>
element needs to be an immediate child of the <manifest>
element, and your code listing above suggests that it is not.
Here is a sample project demonstrating the use of BOOT_COMPLETED
.
Turns out the receiver wasn't in the tag of the manifest. Whoops! Thanks for your help guys! The worst part about testing this is having to keep turning off and on the phone. :P
This seems to be the forefront thread for this problem, so I wanted to add a solution for my C# colleagues. I racked my brain trying to figure out what I was doing wrong after trying everything here, to no avail. I finally figure out what was wrong, and it differs a bit from the advice here for C# Mono development. Basically, it boils down to something I've just learned the hard way. With C# DO NOT MODIFY AndroidManifest.xml manually!
See this guide for reference: Xamarin: Working with AndroidManifest.xml
More directly for this problem, here is how you get this done.
First, in your project properties, under the Manifest Tab, there is a checkbox list for choosing the permissions you want to provide, one of which is RECEIVE_BOOT_COMPLETED. Check that to provide these permissions.
Secondly, you need to put the proper tags on your BroacastReceiver class.
[BroadcastReceiver]
[IntentFilter(new String[]{ Intent.ActionBootCompleted }, Priority = (int)IntentFilterPriority.LowPriority)]
public class MyBootReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
// Do your boot work here, set alarms, show toasts, whatever
}
}
The final part of [IntentFilter()] dealing with priority isn't required, it just lets other higher priority stuff get done first on boot, and is good practice if your App isn't a high priority thing.
As you'll see in the linked article, using these tags in your code will cause the AndroidManifest.xml file to be created at build time, with everything the way it should be. What I found was that when modifying the manifest manually to include the receiver tag, the system was causing it to look for the class one level too deep, thus throwing a ClassNotFound exception. It was trying to instantiate [Namespace].[Namespace].[BroadcastReceiver] which was wrong. And it was doing that because of the manual manifest edits.
Anyway, hope this helps.
Also, another quick tip with the adb tool. If you want to get an easier to read version of the log, try this:
C:\Android\platform-tools\adb logcat >> C:\log.txt
This will dump the logcat to a text file you can open and read a bit easier than in the command prompt window. Makes cut and paste of things a bit easier too.
Pertaining to some devices running Android Kitkat 4.4.4_r2/r1.
There seems to be a bug in Android that make android.intent.action.BOOT_COMPLETED no being broadcasted.
See:
BOOT FAILURE making Package Manager Service ready
In most cases this is not the answer to your problems (more likely because permissions etc), but if you are running Kitkat then you might have a look and see if this seems to be the case for you.
I had this problem and android.intent.action.BOOT_COMPLETED would simply not be broadcasted some of the times it had started up!
Other answers here already covered how to perfectly implement the Broadcast Receiver so that it'll work, however I still had problems receiving the BOOT_COMPLETED Intent until I realized the app was actually working when started from the phone/emulator by pressing on the app icon. Whenever I start my app with the debug/run commands from Android Studio the BOOT_COMPLETED Intent won't be delivered, unless the app is opened and running.
I hope this can help someone who, like me, was struggling for hours with this problem. Moreover, if anyone has an explanation for this behavior, I'd be really happy to know more about it.
on adding <category android:name="android.intent.category.HOME" />
this to my manifest file solve my problem and works.
<receiver android:name=".BroadCastRecieverClass">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>
