Create and run an android project without a device or emulator

Question

I'm trying to create a new Eclipse Project where I can test android classes without having to start the emu or connect a device.

I imported the android libraries, but I can't get it to work... My project only contains one java file where I use an android class, I only want to start it as a simple java app.

The error I get is: "Exception in thread "main" java.lang.RuntimeException: Stub!"

My question is: How can I create a simple java project (in eclipse) which uses android classes?

You can't.

There are no "android classes". Android is an operating system, not a class library. The real "Android classes" exist only in the operating system, either on an emulator or a device. The android.jar file is merely a set of stubs that allows the Java build tools to successfully compile Android applications.

If you have Java code that has no Android dependencies, you can build that in a regular Java project, perhaps creating a JAR file that your Android project then uses.

Answer 2

If your goal is to unit test classes within your Android app, then you should look at creating an Android test project. See Hello, Testing for a step by step guide in setting this up.

Answer 3

有一个android模拟器可以在开发机器上本地运行应用程序，但是它不像模拟器那样健壮或维护得很好，通常只用于非常狭窄的高级任务，这些头疼使运行变得很头疼补充配置文件工具。

Yes you can...

You must use robolectric see documentation here
