In my project, I need to use external library. That library consists of .class files. I have added folder with this library to my project using properties -> Java Build Path -> Libraries -> Add class folder. I can compile project without any problem, but when I run it, I get failed resolving xy and debugger stops on line where I create instance of class from imported files.
I guess the external library I use isnt linked to my .apk file. How can I fix this? I have tried to check this library on "Order and Export" tab assuming that, it will export the library with my application. But it didnt work.
How can I link this library to my project .apk? Do I need to somehow install this library on device first? Do I need to copy this library in application folder?
PS: I'm using Eclipse Juno, android SDK target 10.
Thank you
UPDATE
I have this library copied in libs folder. External library path is:
my_project/libs/sk/aicit/leg/libraries*.class
I have added ./libs folder in Libraries settings of project.
I do not have .jar version of this library, only .class files.
I have also souce code of this library, but I didnt want to include its classes in my project, it has its own dependencies, I wanted to just "link" it like library. Its an external library I havent written.
UPDATE 2
I have copied all the source files from library to my projects "src/" dir. I have removed Library from Java build path. I can stil compile my project, but when I run it Iget
FATAL EXCEPTION:main
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{
com.example/myvideorecord/com.example.myvideorecord.Robot}: java.langNullPointerException
...
What can I do, how to debug this error? :(
