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。
