03-10 17:44:54.071: e/androidruntime(31435): fatal exception: main 03-10 17:44:54.071: e/androidruntime(31435): java.lang.illegalstateexception:  fatal  developer error has occurred. check logs further information. 03-10 17:44:54.071: e/androidruntime(31435):    @     com.google.android.gms.internal.dw$h.b(unknown source) 03-10 17:44:54.071: e/androidruntime(31435):    @ com.google.android.gms.internal.dw$h.b(unknown source) 03-10 17:44:54.071: e/androidruntime(31435):    @ com.google.android.gms.internal.dw$b.br(unknown source) 03-10 17:44:54.071: e/androidruntime(31435):    @ com.google.android.gms.internal.dw$a.handlemessage(unknown source)

console shows:

[2014-03-10 17:47:18 - basegameutils] not find basegameutils.apk!

answer: had 2 metadata entrys appid in manifest. log without filters listed corresponding errors

the 2 entries were

<meta-data         android:name="com.google.android.gms.games.app_id"         android:value="@string/app_id" />     <meta-data         android:name="com.google.android.gms.appstate.app_id"         android:value="@string/app_id" />

only 1 of these entries mentioned in tutorial.

i've finished putting leaderboards , pain, did , works. here's long list of suggestions may directly or indirectly you. use eclipse.

  • for google play api, minimum sdk 9 put in manifest on it's own line:

    < uses-sdk android:minsdkversion="9" android:targetsdkversion="19"/> //whatever target want

  • import basegameutils project workspace. not have modify of code.

  • import google-play-services_lib. in sdk folder. sdk folder next eclipse folder. anyways in: sdk/extras/google/google_play_services/libproject/google-play-services_lib. not have modify of code.

  • right click on yourproject in package explorer tab (normally on left side of eclipse of project folders). click on properties (alt+enter). click on android. on bottom part of android page, should "library." click add button , add basegameutils , google-play-services_lib. not click "is library".

  • ensure of android-support-v4.jar files in relevant projects using same up-to-date version. can update support file right clicking project in "package explorer" tab , going ->android tools->add support library. accept , update. can further check see if of projects listed have updated jar right clicking project , going properties. click on java build path , click on libraries tab. should see support jar listed. if not, can add jar, where-ever located in project. if not this, may have called jar mixmatch. of course, see exact problem in console easy fix , diagnose.

  • your manifest should be: < meta-data android:name="com.google.android.gms.games.app_id" android:value="@string/app_id" /> < meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

the last line @integer looks google_play_services_version don't have in future whenever google play version changes. not hard code version number value or have manually update often.

  • myproject extends basegameactivity.

  • then call leaderboard , update it, sample code of 2 lines of code runs great. see below. https://developers.google.com/games/services/android/leaderboards have pass in leaderboard id given when link app google play developer console. it's string looks like: "dkbgvageybasewefcx." updating , getting leaderboard crash if aren't connected. check out complete sample code below.

    //to update if (getapiclient().isconnected()) //getapiclient part of basegameutils games.leaderboards.submitscore(getapiclient(), leaderboardid, score);

    //to show if (getapiclient().isconnected()) startactivityforresult(games.leaderboards.getleaderboardintent(getapiclient(), leaderboardid), 1337);

  • lastly, if using app different keystore has different sha1 (secure hash algorithm) 1 have on google play store, there error , not able connect. if uploaded app keystore sha1 ab:cd:de... , you're debugging app, may see problems since eclipse use default android debug keystore has different sha1. not able connect , consequently, not able use google play services.

  • i recommend @ sample code called "trivial quest." https://github.com/playgameservices/android-samples it's under eclipse_compat. sample code shows 1 how sign in , unlock achievement. if can sign in, can achievements , leaderboards easily.

  • there's lot of stuff have given small piece of puzzle. if have more problems, please let know.
