静默安装介绍

最近在研究静默安装，研究了一周，本来就放弃了，这个真的不是太容易，一般接触过linux和源码开发的开发者，还是可以的，但是对于做应用层开发的开发者来说就太难，这里也不多说了，我把代码贴出来

下面是android4.0以上的静默代码

package com.zcsj.qianmingjmaz;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;

import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

String fileName = Environment.getExternalStorageDirectory() + "/UC.apk";
install(fileName);

}
public String install(String apkAbsolutePath ){

String[] args = { "pm", "install", "-r", apkAbsolutePath };

String result = "";

ProcessBuilder processBuilder = new ProcessBuilder(args);

Process process = null;

InputStream errIs = null;

InputStream inIs = null;
try {

ByteArrayOutputStream baos = new ByteArrayOutputStream();

int read = -1;

process = processBuilder.start();

errIs = process.getErrorStream();

while ((read = errIs.read()) != -1) {

baos.write(read);

}

baos.write("/n".getBytes());

inIs = process.getInputStream();

while ((read = inIs.read()) != -1) {

baos.write(read);

}

byte[] data = baos.toByteArray();

result = new String(data);

} catch (IOException e) {

e.printStackTrace();

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

if (errIs != null) {

errIs.close();

}

if (inIs != null) {

inIs.close();

}

} catch (IOException e) {

e.printStackTrace();

}

if (process != null) {
process.destroy();

}

}

return result;

}

}

在清单文件添加权限当然这些权限是报错的，需要在源码下编译，这点网上也很少说，

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
<uses-permission android:name="android.permission.DELETE_PACKAGES" />

<uses-permission android:name="android.permission.CLEAR_APP_USER_DATA" />
