So I just recently updated to ADT 20 and it’s been a complete nightmare.

I tried all the solutions I’ve found online.
1. I put the jar into the LIBS folder
2. Added jar from libary tab in the build path & checked it in the export path
3. I even did this one thing where someone said to make the libs folder a source folder (i guess so it get exported)

Nothing works. Please help this is a total nightmare. I can’t use any external jars at all…

    I actually figure out what was wrong right when I posted this. Caused by: com.google.ads.internal.b: Required XML attribute "adUnitId" missing. So stupid, the error logs put it all the way at the bottom.
