屏幕錄制應用程序在 Android 10 上不起作用
[英]Screen recording app does not work on Android 10
問題描述
I have an application for recording a screen, it does not work on android version 10. As I understand it, this is due to privacy changes in force in Android 10. Now for any application using MediaProjection api, must specify an attribute android:foregroundServiceType=在清單下的服務標記中，但我的應用程序在片段中使用MediaProjection ，而不是服務。 是否可以從片段中使MediaProjection工作，還是我需要重做它？
對不起，我的英語不好
這是一個錯誤
Caused by java.lang.SecurityException
Media projections require a foreground service of type ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION
com.example.screen_recording.screens.main_record.MainFragment.onActivityResult (MainFragment.java:321)
這是片段代碼

您應該在片段內使用foreground service來捕獲屏幕。 查找以下鏈接，了解如何使用前台服務來捕獲屏幕。
