问题描述

我有这个记录屏幕的功能。它适用于 Android 6 到 9。从 Andriod 10 开始，问题开始出现。

private void initRecorder() {
    try {
        mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        mediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
        mediaRecorder.setoutputFormat(MediaRecorder.OutputFormat.MPEG_4);
        //VIDEO RATES
        mediaRecorder.setVideoEncodingBitRate(512 * 1000);
        mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264); //Be very careful with the Encoder,it should match the VideoSource
        mediaRecorder.setVideoSize(disPLAY_WIDTH,disPLAY_HEIGHT);
        mediaRecorder.setVideoFrameRate(30);
        //AUdio RATES
        mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_WB);
        mediaRecorder.setAudioEncodingBitRate(96000);
        mediaRecorder.setAudioSamplingRate(44100);

        videoUri = FilingSystem.Companion.getCompletedLectures()
                + "/" + fileName + "_dub_Records_" + new SimpleDateFormat("dd-MM-yyyy-hh-mm-ss")
                .format(new Date()) +
                ".mp4";

        compressedVideo = FilingSystem.Companion.getCompletedLectures()
                + "/" + fileName + "_Compressed_dub_Records_" + new SimpleDateFormat("dd-MM-yyyy-hh-mm-ss")
                .format(new Date()) +
                ".mp4";



        int rotation = getwindowManager().getDefaultdisplay().getRotation();
        int orientation = ORIENTATION.get(rotation + 90);
        mediaRecorder.setorientationHint(orientation);
        mediaRecorder.prepare();
        surface = mediaRecorder.getSurface();
    } catch (IOException e) {
        e.printstacktrace();
    }
}

从函数中可以看出mediaRecorder已经准备好了。所以现在当我在 onActivityResult 中启动它时，因为我必须为此获得一些权限，它适用于 Android 6 到 Android 9。但在 Android 10 中，我收到错误

java.lang.RuntimeException: Failure delivering result ResultInfo{who=null,request=1000,result=-1,data=Intent { (has extras) }} to activity {com.example.ynot/com.example.ynot.Activities.LectureStudio}: java.lang.IllegalStateException
    at android.app.ActivityThread.deliverResults(ActivityThread.java:5589)
    at android.app.ActivityThread.handleSendResult(ActivityThread.java:5630)
