用代码安装apk文件

安装APK程序可以通过连接PC端安装，还有通过网络下载安装。



那如何在代码里控制安装呢？



其实很简单 Intent i = new Intent(Intent.ACTION_VIEW);  

String filePath = "/sdcard/XXX.apk";  

i.setDataAndType(Uri.parse("file://" + filePath),"application/vnd.android.package-archive");  

context.startActivity(i); 

例子
首先push apk文件进去sdcard
package com.org;

import java.io.File;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;

public class ApkUpLoad extends Activity {
    /** Called when the activity is first created. */
 

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
//        File file = new File("/mnt/sdcard");
        Intent intent = new Intent();
        String filePath = "/sdcard/browser2.apk";  
//        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//        intent.setAction(android.content.Intent.ACTION_VIEW);
        intent.setDataAndType(Uri.parse("file://" + filePath),
                        "application/vnd.android.package-archive");
        startActivity(intent);


    }
}
