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】

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。
