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】

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】

 1  private void test() {
 2   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）
 3 
 4   // execCommand("system/bin/pm uninstall " +  PACKAGE_NAME); //PACKAGE_NAME为xxx.apk包名
 5  }
 6 
 7  public boolean execCommand(String cmd) {
 8   Process process = null;
 9   try {
10    process = Runtime.getRuntime().exec(cmd);
11    process.waitFor();
12   } catch (Exception e) {
13    return false;
14   } finally {
15    try {
16     process.destroy();
17    } catch (Exception e) {
18    }
19   }
20   return true;
21  }

其他方法：一些第三方jar包等方式
