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。
