Android获取超级管理员权限的实现

public class MyDeviceAdminReceiver extends DeviceAdminReceiver{
 @Override
 public void onReceive(Context context,Intent intent){
  //TODO
 }
}

 
 
 
 ...

// 判断是否具有ROOT权限
public static boolean is_root(){
 boolean res = false;
 try{ 
  if ((!new File("/system/bin/su").exists()) && 
   (!new File("/system/xbin/su").exists())){
  res = false;
 } 
 else {
  res = true;
 };
 } 
 catch (Exception e) { 
 
 } 
 return res;
}

// 获取ROOT权限
public void get_root(){
 if (is_root()){
  Toast.makeText(mCtx, "已经具有ROOT权限!", Toast.LENGTH_LONG).show();
 }
 else{
  try{
   progress_dialog = ProgressDialog.show(mCtx, 
     "ROOT", "正在获取ROOT权限...", true, false);
   Runtime.getRuntime().exec("su");
  }
  catch (Exception e){
   Toast.makeText(mCtx, "获取ROOT权限时出错!", Toast.LENGTH_LONG).show();
  }
 }

}
