Thanks guys, sorry if my questions are too known, i havent had much time to test the features.
However i get the white map. I have checked the SHA1, correct, Package name, correct, API gey, generated correctly, pasted correctly in the manifest editor... checked the Google maps in the libs... maybe i copied the wrong google apy jar?
Maybe my error is in step 4: - Under "Simple API Access" you should select "Key for Android apps (with certificates".
I cannot follow this step because i dont see the option, My version is in spanish and i dont know what it translates exactly to or where is it or where should i look for it.
