Android 14设备中ServiceCompat.startForeground()崩溃问题求助
我正在开发一款Android应用,核心功能是用户退出应用后仍能持续录制视频,通过前台服务实现。已按官方文档要求在Manifest中声明所有必要权限,并且在运行时授予了全部权限,但在Android 14设备上调用ServiceCompat.startForeground()时应用崩溃,抛出以下SecurityException:
java.lang.SecurityException: Starting FGS with type microphone callerApp=ProcessRecord{25db602 15445:com.nerovero.camerago/u0a1030} targetSDK=34 requires permissions: all of the permissions allOf=true [android.permission.FOREGROUND_SERVICE_MICROPHONE] any of the permissions allOf=false [android.permission.CAPTURE_AUDIO_HOTWORD, android.permission.CAPTURE_AUDIO_OUTPUT, android.permission.CAPTURE_MEDIA_OUTPUT, android.permission.CAPTURE_TUNER_AUDIO_INPUT, android.permission.CAPTURE_VOICE_COMMUNICATION_OUTPUT, android.permission.RECORD_AUDIO] and the app must be in the eligible state/exemptions to access the foreground only permission

已尝试修改Manifest中的服务属性,但问题仍未解决。
