问题
Im trying to code some application that uses Google Maps API. The map is shown in the main activity.
On some phones, including the emulator, the application crashes immediately after starting. The only phone it works with is my Galaxy S1, which runs CM10.1 (4.2.2).
It crashes on my HTC DESIRE HD (4.2.2 as well)

回答1:
Just do the following to check if google play services are available:
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if(status == ConnectionResult.SUCCESS) {
//Success! Do what you want
}else{
GooglePlayServicesUtil.getErrorDialog(status, this, status);
}
It will check for google play services and if are not available it will prompt user to download them from google play
回答2:
It sounds as though the phones you're testing on don't have the latest Google Play Services pre-req's installed.
If you take a look here you'll find a section discussing how you can ensure that devices have the google play service APK installed and if not, direct the user to install it.
Also note that the emulator isn't supported on emulators running an API platform less than Andorid 4.2.2 (referenced here in the first section)
回答3:
I have the same exception on my app:
java.lang.NullPointerException: IBitmapDescriptorFactory is not initialized
In my case, I have to call BitmapDescriptorFactory static method after initializing the Google Map object.
Read the comments:
// This line initilizes the map asynchronously. It requires implementation
// of OnMapReadyCallback interface.
// And when it is inizilized, it calls onMapReady(GoogleMap googleMap)
mapFragment.getMapAsync(this);
// The following method is implemented in my activity
@Override
public void onMapReady(GoogleMap googleMap) {
... some code ...
currentLocationIcon = BitmapDescriptorFactory.fromResource(R.drawable.report_location_current)
... some code ...
}
回答4:
GoogleApiAvailability googleApiAvailability=GoogleApiAvailability.getInstance();
int status=googleApiAvailability.isGooglePlayServicesAvailable(getActivity());
if (status != ConnectionResult.SUCCESS) {
int requestCode = 10;
Dialog dialog = googleApiAvailability.getErrorDialog(getActivity(),status,requestCode);
dialog.show();
}else{}
回答5:
Refer here to check for Google Play Services available on your phone. If you encounter an error then it will display an error dialog returned from Google Play Services. I have worked on my application with Google Maps v2 on Samsung Galaxy S3 and its working fine.
