You don't know Java or how to use your IDE well enough.

I am not using any Java IDE, I am using a script to compile the project and I don't plan on changing that.

Yes, I am not familiar enough with Java to use those complicated things that Android APIs use. If they just used simple methods it would be so much easier... I could just call them all from JNI in Pascal and never use Java. But Google forces developers to use these complicated APIs...

But I would be thankful if anyone could help me getting working.

But I did ... I posted a link to pastebin with the error because if I just copy the text here it will loose the fixed-width font and it won't show anymore where exactly it is pointing too, but since you ask, I will post the error message in raw text here too:
