I tried to debug it.But it does not enter into my broadcastreceiver .Whenever I send a message Android’s default messaging service handles it.What am I doing wrong?
I’m waiting for your answer.Thanks.

I solved my problem by using an https server.My problem was converting a string that contains a byte array into byte array during sending the user’s public key and encrypted messages.Now I’m using a https server to write my staffs and then read from there.It is now more economic.I recommend everyone to use https server who wants to provide encryption in messaging since you may encounter many problem.
