2) How can i read samples programatically?

That I know of, In Android you can record audio using one of this two classes:

• MediaRecorder Class

  Used to record audio and video. The recording control is based on a simple state machine

• AudioRecord class

  The AudioRecord class manages the audio resources for Java applications to record audio from the audio input hardware of the platform. This is achieved by "pulling" (reading) the data from the AudioRecord object. The application is responsible for polling the AudioRecord object in time using one of the following three methods: read(byte[], int, int), read(short[], int, int) or read(ByteBuffer, int). The choice of which method to use will be based on the audio data storage format that is the most convenient for the user of AudioRecord.

Ps: Follow this links above to read and understand the one that best fits your needs.
