使用File对象在Android（API> 24）中捕获和保存视频？

我正在编写要在其中录制视频的代码，然后在录制5秒钟后将其保存。我有以下代码在API <24上正常工作，但是对于API> 24，我得到了错误。

码：

public void startRecording() { File mediaFile = new File(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED) + "/myvideo.mp4");

Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT,5);
fileUri = Uri.fromFile(mediaFile);

intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, VIDEO_CAPTURE);

}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

if (requestCode == VIDEO_CAPTURE) {
    if (resultCode == RESULT_OK) {
        Toast.makeText(this, "Video has been saved to:\n" +
                data.getData(), Toast.LENGTH_LONG).show();
    } else if (resultCode == RESULT_CANCELED) {
        Toast.makeText(this, "Video recording cancelled.",
                Toast.LENGTH_LONG).show();
    } else {
        Toast.makeText(this, "Failed to record video",
                Toast.LENGTH_LONG).show();
    }
}

} 错误：

尽管我可以找到其他有效的代码，但我对此代码是否经过细微调整感到好奇，这也使其适用于API> 24。也许在同一行。

谁可以帮我这个事 ？
