android 实现静默安装、卸载

方法1：【使用调用接口方法，由于安装卸载应用程序的部分API是隐藏的，所以必须下载Android系统源码，在源码下开发并编译之后使用MM命令编译生成APK文件】

import java.io.File;

import android.app.Activity;

import android.os.Bundle;

import android.content.Intent;

import android.content.pm.PackageInfo;

import android.content.pm.PackageManager;

import android.content.pm.PackageManager.NameNotFoundException;

import android.content.pm.IPackageInstallObserver;

import android.content.pm.IPackageDeleteObserver;

import android.content.res.Resources;

import android.graphics.drawable.Drawable;

import android.net.Uri;

import android.os.Environment;

import android.os.Handler;

import android.os.Message;

import android.util.Log;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.ProgressBar;

import android.widget.TextView;

import android.widget.Toast;

public class InstallActivity extends Activity {

/** Called when the activity is first created. */

private String APK_NAME = "QQHD-mini.apk";

private Button install = null;

private Button uninstall = null;

private final int INSTALL_COMPLETE = 1;

private final int UNINSTALL_COMPLETE = 2;

final static int SUCCEEDED = 1;

final static int FAILED = 0;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.install_uninstall);

install = (Button) findViewById(R.id.install);

uninstall = (Button) findViewById(R.id.uninstall);

uninstall.setOnClickListener(listener1);

install.setOnClickListener(listener2);

}

private OnClickListener listener2=new OnClickListener(){

public void onClick(View v) {

String fileName = Environment.getExternalStorageDirectory() + "/" + APK_NAME;

Uri uri = Uri.fromFile(new File(fileName));

int installFlags = 0;

PackageManager pm = getPackageManager();

try {

PackageInfo pi = pm.getPackageInfo("com.tencent.minihd.qq",

PackageManager.GET_UNINSTALLED_PACKAGES);

if(pi != null) {

installFlags |= PackageManager.INSTALL_REPLACE_EXISTING;

}

} catch (NameNotFoundException e) {}

PackageInstallObserver observer = new PackageInstallObserver();

pm.installPackage(uri, observer, installFlags, "com.tencent.minihd.qq");

}

};

class PackageInstallObserver extends IPackageInstallObserver.Stub {

public void packageInstalled(String packageName, int returnCode) {

Message msg = mHandler.obtainMessage(INSTALL_COMPLETE);

msg.arg1 = returnCode;

mHandler.sendMessage(msg);

}

};

private Handler mHandler = new Handler() {

public void handleMessage(Message msg) {

switch (msg.what) {

case INSTALL_COMPLETE:

int centerTextLabel;

Drawable centerTextDrawable = null;

if(msg.arg1 == SUCCEEDED) {

Toast.makeText(getApplicationContext(), "install apk SUCCEEDED", Toast.LENGTH_SHORT).show();

} else {}

if (centerTextDrawable != null) {}

break;

case UNINSTALL_COMPLETE:

int centerTextLabel2;

Drawable centerTextDrawable2 = null;

if(msg.arg1 == SUCCEEDED) {

Toast.makeText(getApplicationContext(), "uninstall apk SUCCEEDED", Toast.LENGTH_SHORT).show();

} else {}

if (centerTextDrawable2 != null) {}

break;

default:

break;

}

}

};

private OnClickListener listener1=new OnClickListener(){

public void onClick(View v) {

PackageManager pm = getPackageManager();

PackageDeleteObserver observer = new PackageDeleteObserver();

pm.deletePackage("com.tencent.minihd.qq", observer, 0);

}

};

private class PackageDeleteObserver extends IPackageDeleteObserver.Stub {

public void packageDeleted(String packageName, int returnCode) {

Message msg = mHandler.obtainMessage(UNINSTALL_COMPLETE);

msg.arg1 = returnCode;

mHandler.sendMessage(msg);

}

}

}

安装、卸载相关权限<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_CACHE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.CLEAR_APP_USER_DATA" />

方法2：【需要获取root权限或者和rom拥有一样的签名，即让该apk以System的身份在系统中运行】

private void test() {

execCommand("system/bin/pm install -r " + "sdcard/xxx.apk"); // xxx.apk放置在内置储存的根目录下（mnt/sdcard/xxx.apk）

// execCommand("system/bin/pm uninstall " + PACKAGE_NAME); //PACKAGE_NAME为xxx.apk包名

}

public boolean execCommand(String cmd) {

Process process = null;

try {

process = Runtime.getRuntime().exec(cmd);

process.waitFor();

} catch (Exception e) {

return false;

} finally {

try {

process.destroy();

} catch (Exception e) {

}

}

return true;

}

其他方法：一些第三方jar包等方式
