Android6.0分了几种权限：Normal Permissions(安装时自动授权，用户也不能取消权限) and Dangerous Permissions

//判断是否有权限// Here, thisActivity is the current activityif (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)//请求权限ActivityCompat.requestPermissions(thisActivity, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, MY_PERMISSIONS_REQUEST_ACCESS_COARSE_LOCATION);//判断是否需要 向用户解释，为什么要申请该权限ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, Manifest.permission.READ_CONTACTS)//权限申请结果onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) |

//如果使用ActivityCompat.requestPermissions，不会调用onRequestPermissionsResult()//请求权限requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, MY_PERMISSIONS_REQUEST_ACCESS_COARSE_LOCATION);//判断是否需要 向用户解释，为什么要申请该权限shouldShowRequestPermissionRationale(Manifest.permission.READ_CONTACTS) |
android.permission.WRITE_SETTINGS不能自动授权，也不能运行时请求授权，咋整啊？通过打开Intent来让用户设置。貌似SETTINGS的权限只能这么处理，from CommonsWare research Android 6.0 changes.
