BOOT_COMPLETED never received

2019-02-26 00:43发布

Does every device send the BOOT_COMPLETED? I want to start an Activity on Boot Completed.

I put the following in the Manifest:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver android:name=".BootFinished">            
    <intent-filter>                
         <action android:name="android.intent.action.BOOT_COMPLETED" />           
    </intent-filter>        
</receiver>

Created the following class (receiver):

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.widget.Toast;

public class BootFinished extends BroadcastReceiver {

    @Override        
    public void onReceive(Context mContext, Intent intent) {
        if(intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {               
          //do something like start an activity or service
        }

        try {
            PackageManager pm = mContext.getPackageManager();
            Intent launch = pm.getLaunchIntentForPackage("com.example.afterboot");
            mContext.startActivity(launch);
        } catch (Exception e) {
            Toast.makeText(mContext, e.getMessage(), Toast.LENGTH_SHORT);
        } 
    }
}

Am I missing something? Thanks!

As a starting point, try putting the full path of your receiver in the manifest.

  1. Add full path and secondly add permission in your receiver.

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

The possible reasons why broadcast reciever events could fail:

  1. Receiver not declared in AndroidManifest.xml Declare the receiver in the Manifest-file:

  2. Receiver in the Manifest xml is misspelled Android-System is case sensitive. So check your spelling and path is correct in the AndroidMainfest.xml

  3. AVD running for a long time Reset your avd/device

4.Also if your app is in moved to sdcard.Say you have registered for android.intent.action.BOOT_COMPLETED,the boot event is triggered even before the mediascanner scans the sdcard.

and all the devices which run android sends BOOT_COMPLETE :P Check again and try :) all the best :)
