我已经授予了其他应用程序的显示权限，但仍然获得"Unable to add window android.view.ViewRootImpl$W@8ab9bbf -- permission denied for window type 2010"
注意事项：如果将目标sdk更改为21，则应用正常运行，这意味着可能存在权限相关问题。
代码：

int totalResultsBack = res2.getCount();
if ((totalResults == 0 && totalResultsBack == 0) || ((totalResults == 0 && totalResultsBack != 0) || (totalResults != 0 && totalResultsBack == 0))) {
finish();

我反编译了应用https://play.google.com/store/apps/details?id=com.lock.admin.screenlock
此应用在最新的android版本中运行完全正常。
