任务“”的执行失败：app:processdebugresources'.
执行com.android.build.gradle.internal.tasks.workers$actionfacade android资源链接失败c:\users\kcs\AndroidStudio项目\ourvedic\app\build\intermediates\packaged\U清单\debug\androidmanifest。xml:11：aapt:error:resource xml/backup\u descriptor（又名com.binni。ourvedic:xml/backup_descriptor)找不到。
