Merhaba arkadaşlar 2 android cihazı aynı ağa baglı wifi üzerinden 1 i client 1 server olmak üzere clientten server a ses gönderimi yapmak istiyorum ancak io exception da hata alıyorum kodlar :

Androidde Audio İnput Stream Kütüphanesi var mıdır ? ben bulamadım eğer yok ise yerine kullanabileceğim bir kütüphane önerirmisiniz?
