Hayho, well my problem is a little tricky to me to explain. I try to connect my android tablet (4.0.3) to a RS-232 converter. That already works, but only oneway. If i try to send anything, it is sended. I cannot receive any answers, but this is neccessary. I get this <pre><code> Logcat Errors: Either Socket is not bound, or EADRESS already in use. </code></pre> I tried multiple ways, but none worked as i need it. My target: Sending AND receiving Bytes whenever they are sent. My Architecture: MainActivity -> calls 2 Asynctasks 1. network, 2. ConcurrentServer network has to send my commands via DataOutputStream. Allright here. ConcurrentServer has to receive incoming Data with DataInputStream, give it to a method in ConcurrentServer class. This method should send an answerbyte. My ConcurrentServer doesn't receive, nor does the method send anything... I hope you can help me with that. Code: <pre><code>package com.example.wettkampftimerbt; import java.io.BufferedReader; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.IOException; import java.io.InputStreamReader;

BTW: this is my code NOW, after experimenting and trying a lot of things. So if anything is doubled, this is the reason. In Cause of I am a newbie on Android it may happens to me. Thanks. EDIT: This link, given by Class Stacker is very good. It`s in detailed and precise. For anyone who's having trouble, check this: <a href="http://docs.oracle.com/javase/tutorial/networking/urls/index.html" rel="nofollow">http://docs.oracle.com/javase/tutorial/networking/urls/index.html</a> Thanks one more time Class Stacker!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
