android 代码控制飞行模式开关 支持4.2以上 root

支持android 4.2以上系统
手机需要获取root权限 通过shell命令开关飞行模式
现在手机大都4.2以上了 代码可以选择性舍弃4.2一下的

  private final static String COMMAND_AIRPLANE_ON = "settings put global airplane_mode_on 1 \n " +            "am broadcast -a android.intent.action.AIRPLANE_MODE --ez state true\n ";    private final static String COMMAND_AIRPLANE_OFF = "settings put global airplane_mode_on 0 \n" +            " am broadcast -a android.intent.action.AIRPLANE_MODE --ez state false\n ";    private final static String COMMAND_SU = "su";

 //判断飞行模式开关  public boolean isAirplaneModeOn()   {  //4.2以下     if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1)      {         return Settings.System.getInt(getContentResolver(),                  Settings.System.AIRPLANE_MODE_ON, 0) != 0;               }      else //4.2或4.2以上     {         return Settings.Global.getInt(getContentResolver(),                  Settings.Global.AIRPLANE_MODE_ON, 0) != 0;     }     }
