    <p>I am trying to work on media extractor for audio streaming of OGG file format on android. I have written some code with help of google documents. but it doesn't work at all. May be i have Written a wrong code or syntax As i am student. <strong>it show me failed to instantiate extractor</strong></p> <pre><code>public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); MediaExtractor extractor = new MediaExtractor(); extractor.setDataSource("http://examplelink.com/ogg");// I cant put real link so sorry for that int numTracks = extractor.getTrackCount(); for (int i = 0; i &lt; numTracks; ++i) { MediaFormat format = extractor.getTrackFormat(i); String mime = format.getString(MediaFormat.KEY_MIME); extractor.selectTrack(i); ByteBuffer inputBuffer = ByteBuffer.allocate(1024); while (extractor.readSampleData(inputBuffer,0) &gt;= 0) { int trackIndex = (int) extractor.getSampleTime(); long presentationTimeUs = extractor.getSampleTime(); } MediaCodec codec = MediaCodec.createDecoderByType(mime); codec.configure(format, null /* surface */, null /* crypto */, 0 /* flags */); codec.start(); ByteBuffer[] inputBuffers = codec.getInputBuffers(); ByteBuffer[] outputBuffers = codec.getOutputBuffers(); format = codec.getOutputFormat(); Long timeoutUs=(long) 1; for (;;) { int inputBufferIndex = codec.dequeueInputBuffer(timeoutUs); if (inputBufferIndex &gt;= 0) { // fill inputBuffers[inputBufferIndex] with valid data codec.queueInputBuffer(inputBufferIndex, 0, 128, 0,0); } MediaCodec.BufferInfo info = new BufferInfo(); int outputBufferIndex = codec.dequeueOutputBuffer(info, timeoutUs); if (outputBufferIndex &gt;= 0) { // outputBuffer is ready to be processed or rendered. codec.releaseOutputBuffer(outputBufferIndex, false); } else if (outputBufferIndex == MediaCodec.INFO_OUTPUT_BUFFERS_CHANGED) { outputBuffers = codec.getOutputBuffers(); } else if (outputBufferIndex == MediaCodec.INFO_OUTPUT_FORMAT_CHANGED) { // Subsequent data will conform to new format. format = codec.getOutputFormat(); AudioTrack mAudioTrack = null; mAudioTrack.setPlaybackRate(format.getInteger(MediaFormat.KEY_SAMPLE_RATE)); } codec.stop(); codec.release(); codec = null; } } </code></pre> <p>}</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
