Question

我收到了一些关于此错误的报告，但我有测试设备，一切顺利。奇怪的是，所有错误报告都是从移动三星发送的。知道如果我无法解决它可能会是什么？错误代码：

        View v = inflater.inflate(R.layout.activity_torrent_player_fragment, container, false);


        mStreamUrl = ((EditText) v.findViewById(R.id.bTorrentUrl)).getText().toString();

        String action = getActivity().getIntent().getAction();
        Uri data = getActivity().getIntent().getData();
        if (action != null && action.equals(Intent.ACTION_VIEW) && data != null) {
            try {
                mStreamUrl = URLDecoder.decode(data.toString(), "utf-8");
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }
        }

        TorrentOptions torrentOptions = new TorrentOptions.Builder()
                .saveLocation(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS))
                .removeFilesAfterStop(true)
                .build();

        torrentStream = TorrentStream.init(torrentOptions);
        torrentStream.addListener(this);

        button2 = (Button) v.findViewById(R.id.button2);
        button2.setVisibility(View.GONE);

        progressBar.setMax(100);



        return v;


    }
    @Override
    public void onResume() {
        super.onResume();
    }

    View.OnClickListener mOnClickListener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            progressBar.setProgress(0);
            if(torrentStream.isStreaming()) {
                torrentStream.stopStream();
                button.setText("Start stream");
                button2.setVisibility(View.GONE);

            Bundle args = getArguments();
            mStreamUrl  = args.getString("url");
            torrentStream.startStream(mStreamUrl);

    };



    @Override
    public void onStreamPrepared(Torrent torrent) {
        Log.d("Torrent", "OnStreamPrepared");
        torrent.startDownload();
    }

    @Override
    public void onStreamStarted(Torrent torrent) {
        Log.d("Torrent", "onStreamStarted");
    }

    @Override
    public void onStreamError(Torrent torrent, Exception e) {
        Log.e("Torrent", "onStreamError", e);
        button.setText("Start stream");
    }

    @Override
    public void onStreamReady(Torrent torrent) {
        progressBar.setProgress(100);
        Log.d("Torrent", "onStreamReady: " + torrent.getVideoFile());


        final String UrlFinalTorrent = torrent.getVideoFile().toString();

        button2.setVisibility(View.VISIBLE);

        button2.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Intent intent = new Intent(getActivity(), MainActivity.class);
                intent.putExtra("url", UrlFinalTorrent);
                startActivity(intent);
            }
        });


    }
    @Override
    public void onStreamProgress(Torrent torrent, StreamStatus status) {
        if(status.bufferProgress <= 100 && progressBar.getProgress() < 100 && progressBar.getProgress() != status.bufferProgress) {
            Log.d("Torrent", "Progress: " + status.bufferProgress);
            progressBar.setProgress(status.bufferProgress);
        }
    }

    @Override
    public void onStreamStopped() {
        Log.d("Torrent", "onStreamStopped");
    }
}

我认为问题来自这里：

        final String UrlFinalTorrent = torrent.getVideoFile().toString();

    button2.setVisibility(View.VISIBLE);

    button2.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Intent intent = new Intent(getActivity(), MainActivity.class);
            intent.putExtra("url", UrlFinalTorrent);
            startActivity(intent);
        }
    });

但正如我所说，我在Android设备和模拟器上尝试了一切，事情正在发挥作用。但是这个错误出现在三星设备上。谢谢。

堆栈跟踪似乎非常清楚地指向为变量mOnClickListener实例化的匿名内部类。这是源类顺序中的第一个内部类，出现在类TorrentPlayerFragment中（如堆栈跟踪所示），它包含对报告为抛出NPE的方法的调用：android.os.Bundle.getString(java.lang.String)。具体地，

            Bundle args = getArguments();
            mStreamUrl  = args.getString("url");

getArguments()很可能在受影响的环境中返回null。这似乎与Android Fragment getArguments() returns null有关，但我不能确信情况或解决方案是相同的。
