Please help me solve this
I had the same issue with Parse and Android for some crazy reason after checking the SDK versions i noticed there was no Target SDK version, but there was one for Min SDK version. I just added the target SDK version ( 8 in this case ) to match the Min version and it works. I guess Parse checks for target SDK version or something.
I hope this may helpful for you.
Open project's properties.
Click on java build path.
Click order and export tab and click on parse jar file to check this.
And build and clean your project then run.
