Android Big Phone screen not filled up

When I put the code that ran for my Android Nexus S on the bigger Android Galaxy Note phones, the screen was not filled up completely, maybe just the top 70%. What I did to fix this was add in this line into the Manifest:

<uses-sdk android:minSdkVersion="4" />

4 or higher works. If you don't have this line, it's assumed to be 1 by default.

Installing gcc and g++ on Mac Lion 10.7.3

1. Install Xcode 4.3 by clicking "View in Mac Apple Store"
          If you want to get an Apple account without a credit card, follow this.

2. Get "Command Line Tools for Xcode" inside Xcode
           Xcode --> Open Developer Tool --> Command Line Tools for Xcode.dmg

3. You now have gcc and g++
          Type which gcc you should see /usr/bin/gcc, and which g++ you should see /usr/bin/g++

Extra notes:
- At first I cannot not find gcc in /usr/bin. Google points me to install Xcode
- After I have Xcode, gcc does not work either. I could not find /Developer. Then I read "/Developer No Longer Exists" in Xcode 4.3

Android TCP and UDP basic code examples

This is a tiny app that has examples for both android TCP and UDP communications.

Remember, you should:

TCP - start the server first, because ServerSocket.accept() blocks

UDP - start the client first, because DatagramSocket.receive() blocks
