android - BOOT_COMPLETED 从未收到

Question

是否每个设备都发送 BOOT_COMPLETED？我想在启动完成时启动一个 Activity 。

我将以下内容放在 list 中:

<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>

创建了以下类(接收器):

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);
        } 
    }
}

我错过了什么吗？谢谢!

1. 添加完整路径，然后在您的接收器中添加权限。

    <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>
