Android log doesn't print

Question

I'm using TarsosDsp and I don't know if my problem is with the library or not. I'd be happy if anyone could help me figure that out. Here's my code:

public class MainActivity extends AppCompatActivity {

private static final String TAG = "MyActivity";
private Handler handler;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    handler = new Handler();
}

protected void run(View view) {
    new AndroidFFMPEGLocator(this);
    new Thread(new Runnable() {
        @Override
        public void run() {
            handler.post(new Runnable() {
                @Override
                public void run() {
                    File externalStorage = Environment.getExternalStorageDirectory();
                    File sourceFile = new File(externalStorage.getAbsolutePath(), "/440.wav");
                    final int bufferSize = 4096;
                    final int fftSize = bufferSize / 2;
                    final int sampleRate = 44100;

                    AudioDispatcher audioDispatcher;
                    audioDispatcher = AudioDispatcherFactory.fromPipe(sourceFile.getAbsolutePath(), sampleRate, bufferSize, 0);
                    audioDispatcher.addAudioProcessor(new AudioProcessor() {

                        FFT fft = new FFT(bufferSize);
                        final float[] amplitudes = new float[fftSize];

                        @Override
                        public boolean process(AudioEvent audioEvent) {
                            float[] audioBuffer = audioEvent.getFloatBuffer();
                            fft.forwardTransform(audioBuffer);
                            fft.modulus(audioBuffer, amplitudes);
                            for (int i = 0; i < amplitudes.length; i++) {
                                Log.println(Log.DEBUG, TAG, String.format("Amplitude at %3d Hz: %8.3f", (int) fft.binToHz(i, sampleRate), amplitudes[i]));
                            }

                            return true;
                        }

                        @Override
                        public void processingFinished() {
                            Toast.makeText(getApplicationContext(), "salam", Toast.LENGTH_SHORT).show();
                        }
                    });
                    audioDispatcher.run();
                }
            });
        }
    }).start();
}

}

The problem is that the log line on

Log.println(Log.DEBUG, TAG, String.format("Amplitude at %3d Hz: %8.3f", (int) fft.binToHz(i, sampleRate), amplitudes[i]));

doesn't print anything. Any help? Here's my log:

P.S. It looks like the process function isn't running. the processingFinished runs though.

Update: It was a problem with handler, I don't know why but when I moved the code inside run(View view) to onTouchEvent it worked fine.

Are you sure that the array `amplitudes` has actual entries to loop over? You should try to print a log message outside of the loop or put a break point inside the loop to make sure the code is actually executing. — Bobbake4, Oct 25 '16 at 17:13
try something like this Log.d("Debug","Debug error to log"); if this should work then you should check the content of string.format — Babajide Apata, Oct 25 '16 at 17:15
@user3484400 What do you mean still does nothing? Did you check to make sure that line is actually executing? Are you positive `amplitudes` contains a few entries? — Bobbake4, Oct 25 '16 at 17:33
@Bobbake4 I can't check the amplitudes because of it's scope (I can't get logs there!!!), and logs outside the loop doesn't work either. — Hassan Pezeshk, Oct 25 '16 at 17:39
Do You call `run()` method from `onCreate()` or other place of code? — Andrii Omelchenko, Oct 25 '16 at 17:42
@user3484400 You can run the application in debug mode and put a break point on a bunch of lines to step through the execution and find where things are going wrong. — Bobbake4, Oct 25 '16 at 17:45
@Bobbake4 Hey i am facing same issue AddAudioprocessor process not excuting and also getting this in logs:CANNOT LINK EXECUTABLE "/data/user/0/com.service.ps.musicplayerpoc/cache/ffmpeg": /data/data/com.service.ps.musicplayerpoc/cache/ffmpeg: has text relocations. Plzz help struggling with this from last 2 days. Thankx in advance — Avinash Jain, May 31 '18 at 10:45

Turn off the instant run feature of Android Studio, uninstall the app, clean the project and then run the app. This helped me once, may be for you. Best of luck.

May be You forgot to call protected void run(View view) method?

Nope, I called that and it runs. – Hassan Pezeshk Oct 25 '16 at 18:07

It turns out android studio (java) works in a weird way when it comes to logging on threads other than main thread.
