BOOT_COMPLETED从未收到 [英] BOOT_COMPLETED never received

问题描述

难道每一个设备发送BOOT_COMPLETED？我要开始启动的活动已完成。

我把下面的清单：

 ＆LT;使用-权限的Andr​​oid：名称=android.permission.RECEIVE_BOOT_COMPLETED/＆GT;
＆LT;接收机器人：BootFinishedNAME =＆GT;
    ＆LT;意向滤光器＆gt;
         ＆lt;作用机器人：名称=android.intent.action.BOOT_COMPLETED/＆GT;
    ＆所述; /意图滤光器＆gt;
＆LT; /接收器＆GT;
 

创建下面的类（接收器）：

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

公共类BootFinished扩展的BroadcastReceiver {

    @覆盖
    公共无效的onReceive（上下文mContext，意图意图）{
        如果（intent.getAction（）。等于（android.intent.action.BOOT_COMPLETED））{
          //像做启动一个活动或服务
        }

        尝试 {
            PackageManager下午= mContext.getPackageManager（）;
            意向推出= pm.getLaunchIntentForPackage（com.example.afterboot）;
            mContext.startActivity（发射）;
        }赶上（例外五）{
            Toast.makeText（mContext，e.getMessage（），Toast.LENGTH_SHORT）;
        }
    }
}
 

我缺少的东西？谢谢！

解决方案

1. 添加完整路径;其次在接收器添加许可。

    ＆LT;接收器的Andr​​oid版本：NAME =com.example.BootFinished
      机器人：权限=android.permission.RECEIVE_BOOT_COMPLETED＆GT;
       ＆LT;意向滤光器＆gt;
          ＆lt;作用机器人：名称=android.intent.action.BOOT_COMPLETED/＆GT;
       ＆所述; /意图滤光器＆gt;
    ＆LT; /接收器＆GT;
    

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!

解决方案

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>
