I have again a question: I found in play.google.com, that WhereYouGo needs Android 1.6. If I compile the code with API 4 (Android 1.6) I get some errors (MATCH_PARENT could not be resolved, killBackgroundProcesses(String) is undefined). If I search for killBackgroundProcesses(), I found, that this function is from API 8 (Android 2.2). Now my question: do I have at least to use API 8 to compile WhereYouGo?
