    c. Build the Android APK (Limbo.apk) from Eclipse or Netbeans.
    		 
    	** Make sure the *.so libraries are zipped in the final .apk
    	(Eclipse should do that automatically) 
    	
   	d. Build the debugging version:
   		i. Modify debuggable flag in AndroidManifest.xml to true
   		ii. Modify android-config.mak and point to a configuration 
   			with no optimization: 
   			ie android-generic-armv5te-softfp-noopt.mak
   		ii. From the command line type:
   			make NDK_DEBUG=1
   			
    e. If you want to build the ARM Emulator update qemu.config.mak file:
    TARGET_LIST = arm-softmmu
    
    f. For ARMv7 phones:
        i. Update android-config.mak and include file android-generic-armv7a-vfpv3d16.mak
