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 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.IPackageDeleteObserver;

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.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.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android.permission.INSTALL_PACKAGES" />

<uses-permission android.permission.DELETE_PACKAGES" />

<uses-permission android.permission.CLEAR_APP_CACHE" />

<uses-permission android.permission.READ_PHONE_STATE"/>

<uses-permission 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
