Android APK安装完成自动删除安装包

需要实现此功能，一般实际开发是在自动版本更新上，当更新完开始自动安装完毕后，删除内存卡里的安装包。实现方式很简单，监听应用广播，获取内存卡下的文件，删除！ 1、监听广播

package com.example.a75213.testdownloaddemo;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.widget.Toast;import com.example.a75213.testdownloaddemo.contant.comm;/** * Created by 75213 on 2017/11/7. */public class InitApkBroadCastReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        if (Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction())) {            comm.rmoveFile("http://imtt.dd.qq.com/16891/7C7BB50B68B684A36339AF1F615E2848.apk");            Toast.makeText(context , "监听到系统广播添加" , Toast.LENGTH_LONG).show();        }        if (Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction())) {            comm.rmoveFile("http://imtt.dd.qq.com/16891/7C7BB50B68B684A36339AF1F615E2848.apk");            Toast.makeText(context , "监听到系统广播移除" , Toast.LENGTH_LONG).show();            System.out.println("");        }        if (Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())) {            comm.rmoveFile("http://imtt.dd.qq.com/16891/7C7BB50B68B684A36339AF1F615E2848.apk");            Toast.makeText(context , "监听到系统广播替换" , Toast.LENGTH_LONG).show();        }    }}

2、记得给删除权限和广播注册【AndroidMainifest】

3、删除工具类

package com.example.a75213.testdownloaddemo.contant;import android.os.Environment;import java.io.File;/** * Created by 75213 on 2017/11/1. */public class comm{    public static File getPathFile(String path){        String apkName = path.substring(path.lastIndexOf("/"));        File outputFile = new File(Environment.getExternalStoragePublicDirectory                (Environment.DIRECTORY_DOWNLOADS), apkName);        return outputFile;    }    public static void rmoveFile(String path){        File file = getPathFile(path);        file.delete();    }}
