Can not open file from storage with superpowered sdk

Question

I am using superpowered sdk for playing audio files. For this I use

player->open("/storage/emulated/0/0567894638.mp3");

I also add permission READ_EXTERNAL_STORAGE.

The issue is, there is no errors displaying but can not play file. If I take this same file from assets then it is successfully playing. Please someone tell me what changes i do for play from internal storage?

Answer 1

String file_path = "/storage/emulated/0/kal.mp3";
File f = new File("" + file_path);
fileLength = (int) f.length();

Pair<Integer, Integer> deviceAudioInfo = getDeviceAudioInfo();
Integer sampleRate = deviceAudioInfo.first;
Integer bufferSize = deviceAudioInfo.second;
SuperpoweredExample(sampleRate, bufferSize, file_path, 0, fileLength);


SuperpoweredExample::SuperpoweredExample(unsigned int samplerate, unsigned int buffersize,
                                     const char *path, int fileOffset, int fileLength) : volume(1.0f * headroom) {
stereoBuffer = (float *) memalign(16, (buffersize + 16) * sizeof(float) * 2);

player = new SuperpoweredAdvancedAudioPlayer(&player, NULL, samplerate, 0);
player->open(path);

audioSystem = new SuperpoweredAndroidAudioIO(samplerate, buffersize, false, true,
                                             audioProcessing,
                                             this, -1, SL_ANDROID_STREAM_MEDIA, buffersize * 2);
}

add permission READ_EXTERNAL_STORAGE
