Write serial data to Arduino

Physicaloid mPhysicaloid = new Physicaloid(this);
if( {
    byte[] buf = "moemoe".getBytes();
    mPhysicaloid.write(buf, buf.length);

Read serial data from Arduino

Physicaloid mPhysicaloid = new Physicaloid(this);
TextView TextView1 = (TextView) findViewById(;// Android TextView

if( {
    byte[] buf = new byte[256];, buf.length);
    String str = new String(buf);
