Currently, I go to properties-> build path-> libraries -> and then add external jars to my classpath, I know this is the correct way to do this, for java at least. However, the issue is I am running it on the Android SDK 2.1. When I run the program, I do not think the android emulator can "find" the .jars in the classpath. Is this possible? If so, which folder do I put the jars before adding them to my classpath?
You can try doing it in eclipse by
Right Click the jar --> Build Path --> Add to build path
1) Go to your Finder / Explorer and select your .jar files 2) Drag your .jar files into Eclipse, (make sure to put them in your desired Project) 3) right click on each jar -> "build path" -> "add to build path"
What is the output of the LogCat?
if you are using native code in your projects you must include the so files in libs->armeabi folder. stuff like box2d, chipmunk, xml2, etc...
