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】

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<receiver
            android:name=".InitApkBroadCastReceiver"
            android:enabled="true">
            <intent-filter>
                <action android:name="android.intent.action.PACKAGE_ADDED" />
                <action android:name="android.intent.action.PACKAGE_REPLACED" />
                <action android:name="android.intent.action.PACKAGE_REMOVED" />

                <data android:scheme="package" />
            </intent-filter>
        </receiver>

 

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();
    }
}
