To create an custom button in Android create a subfolder called drawable in the res directory.

Then create an xml file save is as custom_button.xml or what ever you chose to name it.

below is content for your custom button

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"

    <solid android:color="#00ff00" />

        android:topRightRadius="7dp" />
        android:color="#ff0000" />


solid sets the hex color of the button, corners set the corner radius ( rounded corders ), stroke set a border color for the button.

How to use Android Samsung Galaxy S for developement

BY: Mike Zriel

To use an Android device for development so it appears in the DDMS, you need to turn to Activate USB Debugging.

The following are instructions how to do this on a Samsung Galaxy S, which I am using as a test phone.

  • Press the Menu Button
  • Settings
  • Applications
  • Development
  • Press on the checkbox for USB debugging ** you must unplug the phone from USB when you do this **
  • Plug the USB back into the phone and if all goes well, you should see your device listed in DDMS in Eclipse

Side note: to see DDMS in Eclipse, Click "Window" -> "Open Prospective" -> "Other" -> "DDMS"
