如何解决marshamallow或更高版本中的权限检查问题？

我正在申请中，我想检查棉花糖和以上的权限。我在Splash屏幕中使用了许可代码。现在我想要的是，当我启动应用程序时，第一个启动画面出现5秒钟，然后重定向到家庭活动并检查权限。现在我面临的问题是只有在屏幕连续显示和没有任何事情发生。我怎么解决这个问题？在清单如何解决marshamallow或更高版本中的权限检查问题？

代码的权限检查从来没有运行。我看到你可能想要在onPostResume方法中启动它，但sentToSettings变量被初始化为false，因此权限检查从不运行。

@Override 
protected void onPostResume() { 
    super.onPostResume(); 
    if (sentToSettings) { 
     if (ActivityCompat.checkSelfPermission(SplashActivity.this, permissionsRequired[0]) == PackageManager.PERMISSION_GRANTED) { 
      //Got Permission 
      proceedAfterPermission(); 
     }else { 
      getPermission(); 
     } 
    } 
}
