问题
I am developing a simple application to show a map. For this i am testing my application on a real device as: Samsung Galaxy Europa (Android 2.2). Unfortunately my application is being closed/crashed forcely with lots of errors being viewed in logcat (i am mentioning along with my code). I have included google_play_services_lib as per the rules but in-vain. And Yes i have scratched every bit of solutions mentioned here like:
- Solution 1 - Google play services out of date
- Solution 2 - Google play services out of date
- Solution 3 - Google play services out of date
- Solution 4 - Google play services out of date
- Solution 5 - Google play services out of date
- Solution 6 - Google play services out of date
- Solution 7 - Null pointer exception calling fragment
But applying these out of so many other solution didn't come to fruition. And my application is still crashing. I have even tested my application on online Manymo emulator but my application is crashing there as well on emulator. Is only my google play services version a cause that is not letting my app to run or something else? I am going to put my code and every other bit so you guys can have a look to dig-out the root cause.

LatLng latLng = new LatLng(-33.796923, 150.922433);
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
googleMap.addMarker(new MarkerOptions()
.position(latLng)
.title("My Spot")
.snippet("This is my spot!")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));

回答1:
Since you have a device that has 2.2 you cannot use any google play services version any higher than 3.2 (I believe that is where support for froyo stopped).
you are using the newest version of google play services which will not work with 2.2
You need to download and use Google Play Services for Froyo in the SDK Manager
