Question

我正在使用VideoView播放实时流，并且它在大多数情况下都可以正常工作，但有时应用程序会冻结片刻并继续播放或崩溃并将我发送到主屏幕。当我从列表视图中选择一个项目或点击KEY_DOWN / KEY_UP：

时会发生这种情况

public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_DPAD_DOWN) {
        if (mVideoView != null && mListView == null) {
            if (listViewNext != listViewCurrent) { playChannel(listViewNext, 0); }
            return true;
        }
    }
}

private void playChannel(int channel, int id) {
    listViewCurrent = channel;
    listViewNext = listViewCurrent + 1;
    listViewPrev = listViewCurrent - 1;
    if (mListViewChannels == "Danish") {
        if (listViewNext >= arrayDanishChannels.size()) { listViewNext = 0; }
        if (listViewPrev < 0) { listViewPrev = arrayDanishChannels.size() - 1; }
        mListViewLink = arrayDanishLinks.get(listViewCurrent);
    } else if (mListViewChannels == "World") {
        if (listViewNext >= arrayWorldChannels.size()) { listViewNext = 0; }
        if (listViewPrev < 0) { listViewPrev = arrayWorldChannels.size() - 1; }
        mListViewLink = arrayWorldLinks.get(listViewCurrent);
    }

    String listViewName = (String) listView.getItemAtPosition(listViewCurrent);

    String[] links = mListViewLink.split(";"); int temp = id + 1;
    if (id < 0 || temp > links.length) { id = 0; temp = 1; }
    mListViewLink = links[id]; listViewLinkId = temp; listViewLinkIds = links.length;

    startVideo(listViewName+" ("+listViewLinkId+"/"+listViewLinkIds+")", mListViewLink);

    mListViewCurrent = mListViewChannels;
}

private void startVideo(String title, String link) {
    toastDisplay.cancel();
    setInfoView(title);
    imageView.setVisibility(ImageView.INVISIBLE);
    videoView.removeCallbacks(videoRunnable);
    videoView.stopPlayback();
    MediaController media = new MediaController(MainActivity.this); media.setAnchorView(videoView); media.setMediaPlayer(videoView);
    videoView.setMediaController(media);
    videoView.setVideoPath(link);
    videoView.setOnPreparedListener(videoViewPreparedListener);
    videoView.setOnErrorListener(videoViewErrorListener);
    videoView.setVisibility(VideoView.VISIBLE);
    videoView.postDelayed(videoRunnable, videoViewTimeOut);
    videoView.start();
    mVideoView = "true";

    SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(MainActivity.this);
    SharedPreferences.Editor edit = pref.edit();
    edit.putString("setLastStream", title+";"+mListViewChannels);
    edit.apply();
}
private void setInfoView(String title) {
    infoView.removeCallbacks(infoRunnable);
    infoView.setText(title);
    infoView.setVisibility(TextView.VISIBLE);
    progressBar.setVisibility(ProgressBar.VISIBLE);
}

只需注意：我已经支付了流量，有些可以免费访问任何人，没有非法内容。我使用的是带有固件4.4.2的Android机顶盒我试图在任何地方添加try { .. } finally { .. }，它有时会在随机时间冻结。请帮助，我是新的制作应用程序，这真的让我发疯。抱歉我的英语不好。
