本文实例讲述了android实现静默安装与卸载的方法。分享给大家供大家参考。具体如下:

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。

希望本文所述对大家的Android程序设计有所帮助。
