There is no FM radio support in the Android SDK. Various device manufacturers may have hacked in their own FM radio support, but you would have to contact those manufacturers to learn what APIs, if any, they have for them.

try this code

    int audioSource = MediaRecorder.AudioSource.VOICE_DOWNLINK;  
    int sampleRateInHz = 8000;  
    int channelConfig = AudioFormat.CHANNEL_CONFIGURATION_MONO;  
    int audioFormat = AudioFormat.ENCODING_PCM_16BIT;  
    bufferSize = AudioRecord.getMinBufferSize(sampleRateInHz,  
            channelConfig, audioFormat);  
    AudioRecord recordInstance = new AudioRecord(audioSource,  
            sampleRateInHz, channelConfig, audioFormat, bufferSize);  
    recordInstance.startRecording();
