I have a question to which I have not found an answer, sorry if repeated I upgraded to sdk and ADT 17 and since then every time I open a project leading, for example, advertising admob google gives me error:
Could not find class 'com.google.ads.AdView' ...
This strikes me in all projects that include libraries (jars)
I have read about in this SDK has changed something about it, but my English is not very good (use google translator) and I understand that I am doing wrong.
I appreciate any help.
Best regards
