如何从我的应用程序共享音频文件

Question

因此，我尝试将操作栏共享图标中的应用创建的音频分享到声音云。当我完成录制音频时，我点击图标，声音云确实会出现，但是当我点击它时，它会进入声音云，然后立即回到我的应用程序而不是共享。

以下是我开始保存过程和共享过程的记录活动

//convert inputstream to byte array
public static byte[] getBytesFromInputStream(InputStream is)
{
    ByteArrayOutputStream os = new ByteArrayOutputStream();
    try
    {
        byte[] buffer = new byte[0xFFFF];
                for (int len; (len = is.read(buffer)) != -1;)
            os.write(buffer, 0, len);
                os.flush();
                return os.toByteArray();
    }
    catch (IOException e)
    {
        return null;
    }
}

public void saveInputStream(InputStream is) throws IOException
{
    int n = 0;
    DataInputStream in1;
    in1 = new DataInputStream(is);
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
try 
    {
        while ((n = in1.read()) != -1) 
        {
            bos.write(n);
        }
    } 
    catch (IOException e) 
    {   
        e.printStackTrace();
    }
    ByteBuffer bb = ByteBuffer.wrap(bos.toByteArray());
    bb.order(ByteOrder.LITTLE_ENDIAN);
    ShortBuffer sb = bb.asShortBuffer();

    for (int i = 0; i < sb.capacity(); i++) {
        beatsShortList.add(sb.get(i));
    }
}
//add zeros to shorter audio

        { 
        l2.add((short)0);
        }
    }

        {

    public short[] buildShortArray(List<Short> list)
    {
        short[] arr = new short[list.size()];

        {
            arr[i] = list.get(i);
        }
