通过下面的代码获取AppOpsManager MODE

private static int checkOp(Context context, int op){ if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT){ Object object = context.getSystemService(Context.APP_OPS_SERVICE); Class c = object.getClass(); try { Class[] cArg = new Class[3]; cArg[0] = int.class; cArg[1] = int.class; cArg[2] = String.class; Method lMethod = c.getDeclaredMethod("checkOp", cArg); return (Integer) lMethod.invoke(object, op, Binder.getCallingUid(), context.getPackageName()); } catch(NoSuchMethodException e) { e.printStackTrace(); LogUtils.e("permission:: NoSuchMethodException"+e.getMessage()); } catch (IllegalAccessException e) { e.printStackTrace(); LogUtils.e("permission:: IllegalAccessException"+e.getMessage()); } catch (IllegalArgumentException e) { e.printStackTrace(); LogUtils.e("permission:: IllegalArgumentException"+e.getMessage()); } catch (InvocationTargetException e) { e.printStackTrace(); LogUtils.e("permission:: InvocationTargetException"+e.getMessage()); } } return -1; }

测试流程：

每次通过设置界面修改 app 拨打电话权限，查看打印的值

测试结果(都是6.0以下的系统)：

1. 小米 ，锤子手机正常

2. 魅族MX5、OPPO R9S 不管怎么切换权限返回值都为0

请问各位如何拿到当前的权限状态？
