Question

Using Eclipse for Android development... Going to make a geocaching application so to start I need help with this. I cannot get Eclipse to allow me to debug once I have either view of the xml file on. Even for Hello World....I have android sdk in the right folder, and set up how it should I think. It just won't debug so if you can help me with that, great.

I also need to:

Using the Intent, startActivity() method, crea te buttons that will allow the user to call up a screen or, where appropriate, close (finish) the current screen. Make them attractive and play with an appropriate layout.

Create a button for each of the following:

A splash screen

Main Menu screen

User Profile screen

Game Play screen

Help screen

Thanks in advanced

Explanation / Answer

ok..first I will explain installation steps... so that you can correct where you made installation wrong...

step 1) First run the .exe file you downloaded.

step2) Set up environment variables

Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for exampleC:Program FilesJavajdk1.7.0_21.

step 3)

The individual tools and other SDK packages are saved outside the Android Studio application directory. If you need to access the tools directly, use a terminal to navigate to the location where they are installed. For example:

Users<user>sdk

step4) downlad required tools
