In my Intellij Idea project I had to add both  google-play-services lib and google-play-services jar to the project  And in google-play-services lib project add google-play-services jar too  After that  if you did all things  that described here  right  your application should be working

User · Answer

By now  demo can work follow this link   For example demo  it can work too    Add two jar in libs directory in your project  Follow below information  In particular  I think you need to    Import the actual source for the  google-play-services lib  project and link it as an Android library   Do this through Project -  Properties -  Android -  Library  Add -  google-play-services lib  you can right click on your project and choose Properties  then select Android   Do not add it as a dependent Project through the  Java Build Path  for your project  that didn t work for me   Add the google-play-services jar and android-support-v4 jar into a  libs  folder in the sample project  and add them as  External External JARs  in  Build Path -  Configure Build Path -  Libraries     I found this second step was necessary as I was hitting the exact same error as you when trying to use the sample code  The first step was necessary to avoid a NoClassDefFoundError in com google android gms R styleable in my real project   I also needed to do a Clean build and Uninstall the app from the device  from an earlier test attempt  before the sample code worked   thanks your help very much

I think it is worth mentioning  after I spent over an hour pulling out my hair  that if you are using MapFragment you cannot use FragmentActivity  SupportMapFragment will function fine in this environment    I was just about ready to give up on it

To take care of the Drive-related imports  you ll need a few jars from the Google Drive SDK  There are a few large ones  so you may want to add them individually to suit your app   If that doesn t resolve the com google android gms   imports  the Google Play Services add-on needs to be installed  from Extras - gt  Google Play Services in the SDK Manager  and google-play-services jar needs to be added to your build path   EDIT   In this case  the following jars were needed   google-api-services-drive-v2-rev1-1 7 2-beta jar  google-http-client-1 10 3-beta jar  google-http-client-android2-1 10 3-beta jar  google-oauth-client-1 10 1-beta jar  google-api-client-android2-1 10 3-beta jar  google-api-client-1 10 3-beta jar

It is stated on the same tutorial that     Please note that the code below is only useful for testing your   settings in an application targeting Android API 12 or later   Just change your min SDK version to 12 and it will works   lt uses-sdk         android minSdkVersion  8          android targetSdkVersion  15    gt    Haven s tried Aurel s workaround for older versions of the API yet

Do not forget to actually build the google-play-services lib   That s why it shows the  Could not find google-play    apk   For me  on Eclipse  no other hacks were needed  but to reference the project from the Android submenu  not from Java build path  or Project references or whatever else  No manually placed jars  no nothing were actually needed for me

I faced the same problem ant it took me tow days to figure out a solution  that worked for me    Delete the project google-play-services lib  right click on the project delete   Delete the project containing the Google maps demo   MainActivity in my case   if you have one Copy the  project google-play-services lib  extras google google play services libproject google-play-services lib  into your workspace then import it as General project   File- gt import- gt existing projects into workspase    Right click on your project   in which you want to load the map   - gt  Android - gt  add  under library   google-play-services lib  You should see something like this    Note   You should not have something  like this   the project should be referred from your workspace     I think that the problem is that tow projects are referencing the same library

User · Answer

I don t get the true solution but I solve it after doing these things  - Tick  Copy projects into workspace  when importing google-play-services lib - Don t set the minSdkVersion below 13 - If you get error with theme  try changing your layout theme to any system theme - Re-create your project from scratch or revert everything if you get it from somewhere

Please read carefully     If everything is woking same as google code then please check manifest file in my case i added geo key and map key that s why exception occurs    Note - do not add two keys in manifest file remove map key  meta-data         android name  com google android maps v2 API KEY          android value   string google maps key   gt    add this code     lt meta-data         android name  com google android geo API KEY          android value   string auto location   gt     lt meta-data         android name  com google android gms version          android value   integer google play services version   gt

First Step  http   developer android com tools projects projects-eclipse html ReferencingLibraryProject Second Step  http   developer android com google play-services setup html On that page it has a NOTE but we didn t pay attention   Note  You should be referencing a copy of the library that you copied to your source tree   you should not reference the library from the Android SDK directory   But I think it s not a good way of documentation

User · Answer

In your MainActivity  or in each activity you want to put the v2 map  you must extend FragmentActivity or Activity either you want to use SupportMapFragment or just MapFragment  Use MapFragment class only if you are targeting API 12 and above  Otherwise  use SupportMapFragment  It s a subtle difference but it makes the error

I got the same problem and just Installed Play Services from SDK and all problems fly away

User · Answer

It was a little difficult because it was different in the previous API  but I found a solution   Google says what to do here  according with the question we need com google android gms classes so it is necessary to setup the google play services  which is just a library that we have to add to our project like this link   It s very important to import the copy of the project library google-play-services lib not the one that is in the sdk folder  Once that s done  the tutorial from Google goes perfectly

User · Answer

Maybe You must highlight this       Note  Google Play services is not supported on the Android emulator     to develop using the APIs  you need to provide a development device such as an Android phone or tablet    http   developer android com google play-services setup html  You must provide a physical development device on which you can run and debug your app  Do not use emulator  Will not working

This might be of help to some   I had two projects  one which was a copy of the demo from Google and that worked fine   Another I copied into an existing project and I could not get it to run at all   And in the second failing one I was getting the error message described above   My problem was due to a library not enabled  even though I rebuilt  imported multiple times etc   Right-click on the project -  Properties -  Java Build Path -  Order  amp  Export tab   On the failing project the  Android Private Libraries  tab was unchecked   Once I enabled it the project worked fine

As Google map is wrapped under Fragments now  extend your activity from FragmetActivity not just Activity and make sure if you use  supporrtMapFragment  then you are importing Fragment from support package only
