Share to everyone for your reference. as follows: Bitmap Logobitmap = Bitmapfactory.decoderesource (Mcontext.getresources (), R.drawable.arcnote_logo); Bytearrayoutputstream Logostream = new Bytearrayoutputstream (); Boolean res = logobitmap.compress (bitmap.compressformat.png,100,logostream); Read the image to the Logostream byte[] logobuf = Logostream.tobytea

Short[buffersize]; Audiorecord.startrecording (); LOG.I (TAG, "Start recording"); IsRecording = true; while (isrecording) {int bufferreadresult = audiorecord.read (buffer, 0, buffersize); for (int i = 0; i If you want to debug these PCM files to do audio testing, I recommend using audacity this software, you can see, I directly click on the upper left corner of the file-import-source files, and then set 16K So you can debug it.
