引用Android库项目错误

Question

I am having issues getting my project that references an Android Library to compile. I have exactly followed the instructions in the documentation here: http://developer.android.com/tools/projects/projects-eclipse.html

My android library is is marked as a library correctly, and I can see the jar file and all my .class files in my project. But the classes are not found when I try to reference them in my new project and it will not compile. What am I doing wrong?

Here is a screenshot (SoundGraphingLibrary is my library project and SoundGraphingLibrary is the project I need to use the library in):

Answer 1

确保项目和库项目在同一文件夹中。

Answer 2

First, run Project->Clean on the library, then your project as @iagreen suggests. Then go ahead and close and reopen eclipse. Wait for everything to build.

Assuming nothing is better at this point, click on the library and do Project->Properties->Android . Confirm that Is Library is checked. Now, delete any instance of the library *.jar in your project. Do Project->Properties->Android on your project. Click Add... and click on the library you want, OK , Apply , OK .

That should do it. Also, fire lemurs.

Answer 3

Not sure if this helps but i did the following

• Remove and adding the library by going to Project->Properties->Android.
• Clear the project by going to Project->Clean
• Restart Eclipse and tata it works.
