For this you want to use the AudioRecord class (http:// developer.android.com/reference/android/media/AudioRecord.html). The read methods will return you pure PCM samples in either 8-bit or 16- bit mono or stereo depending on what you set in the constructor of the AudioRecord. The 16-bi PCM samples are signed, no idea about the 8-bit samples but they probably are unsigned. This means that the amplitude in 8-bit can range from 0 to 255 and in 16-bit from -32k to +32k. I'd go with 16-bit in most cases.
