Progress bar not animating

[JeremyPacker]

Hello,

I tried running this in an application and for whatever reason I can't get the progress bar to animate up. It just stays flat. I have checked the bytes, and things look good. I even tried the static bytes array in your sample app with no prevail. Thank you!

Here is my code
` mBeatWaveFormIV.setRawData(getByte(mAudioFile.getAbsolutePath()), new OnSamplingListener() {
@OverRide
public void onComplete() {
Log.d("audio", "Completed");
}
});

private byte[] getByte(String path) {
byte[] getBytes = {};
try {
File file = new File(path);
getBytes = new byte[(int) file.length()];
InputStream is = new FileInputStream(file);
is.read(getBytes);
is.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Log.d("Bytes", getBytes.length+"");
return getBytes;
}

Hey @JeremyPacker, that's pretty odd, I'll check this issue ASAP and will reply with more concrete explanation(or fix)

[JeremyPacker]

Thanks for the quick response @alxrm , if you need any more information let me know and i'll get you anything you need!

[JeremyPacker]

After some more debugging I realized the file that I was calling this method on the path prior to it being decoded to PCM / Raw data. Assuming it wouldn't work for encoded data, I switched that up, I was able to get it to display!

Glad everything ended up good

Hi @JeremyPacker could you explain what did you do eventually? I'm getting the same flat bars. Tried a 200kb mp3 and 1.5mb wav, resulting byte array looks okay but the bars stay flat.

These are the 2 different methods I tried to use to get the byte array:

        static byte[] convertStreamToByteArray(InputStream is) throws IOException {
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            byte[] buff = new byte[10240];
            int i = Integer.MAX_VALUE;
            while ((i = is.read(buff, 0, buff.length)) > 0) {
                baos.write(buff, 0, i);
            }
            return baos.toByteArray();
        }

        static byte[] toByteArray(InputStream in) throws IOException {
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            int read = 0;
            byte[] buffer = new byte[1024];
            while (read != -1) {
                read = in.read(buffer);
                if (read != -1)
                    out.write(buffer,0,read);
            }
            out.close();
            return out.toByteArray();
        }

And when I set the raw data, onComplete does not get called:

                waveView.setRawData(soundBytes, new OnSamplingListener() {
                    @Override
                    public void onComplete() {
                        Log.d(TAG, "asdasd");
                    }
                });

Thanks in advance!

@laurentiusandre hey, let me test the sample app first

[alxrm]

@laurentiusandre so I just tested this and it worked just as intended:

    final Random random = new Random();
    final byte[] data = new byte[1024 * 200];
    random.nextBytes(data);

    waveView.setRawData(data, new OnSamplingListener() {
      @Override public void onComplete() {
        Log.e("DBG", "Done downsampling");
      }
    });

Logs showed:

rm.com.audiogram E/DBG: Done downsampling

I'm going to update sample activities a bit, so they will make a bit more sense

[laurentiusandre]

Okay so I tried your code with Random byte array but I still couldn't get it work. I did some testing and it seems like the bars isn't getting updated because I placed it inside a ViewAnimator (inside a nested RecyclerView but I don't think RV is the problem). Could you take a look at this?

I can use other ViewGroup for a workaround, but you may want to solve this odd bug for future users. Thanks for the great library!
