+Here's an explanation of the files in the Android project, so you can customize them:
+
+android-project/
+	AndroidManifest.xml	- package manifest, do not modify
+	build.properties	- empty
+	build.xml		- build description file, used by ant
+	default.properties	- holds the ABI for the application, currently android-4 which corresponds to the Android 1.6 system image
+	local.properties	- holds the SDK path, you should change this to the path to your SDK
+	jni/			- directory holding native code and Android.mk
+	jni/Android.mk		- Android makefile that includes all subdirectories
+	jni/SDL/		- directory holding the SDL library files
+	jni/SDL/Android.mk	- Android makefile for creating the SDL shared library
+	jni/src/		- directory holding your application source
+	jni/src/Android.mk	- Android makefile that you should customize to include your source code and any library references
+	res/			- directory holding resources for your application
+	res/drawable-*		- directories holding icons for different phone hardware
+	res/layout/main.xml	- place holder for the main screen layout, overridden by the SDL video output
+	res/values/strings.xml	- strings used in your application, including the application name shown on the phone.
+	src/org/libsdl/app/SDLActivity.java	- the Java class handling the initialization and binding to SDL.  Be very careful changing this, as the SDL library relies on this implementation.

+Once you've copied the SDL android project and customized it, you can create an Eclipse project from it:

+ * Enter the name you'd like your project to have
+ * Select "Create project from existing source" and browse for your project directory

+You can create and run an emulator from the Eclipse IDE:
+ * Window -> Android SDK and AVD Manager
+
+You can see if adb can see any devices with the following command:
+	adb devices
+
+You can see the output of log messages on the default device with:
+	adb logcat
+
+You can push files to the device with:
+	adb push local_file remote_path_and_file
