Could not find BaseGameUtils.apk

For the last 2 days I've been trying to simply get Google play game services Integrated into my game. I've followed the instructions here...
https://github.com/playgameservices/android-basic-samples/blob/master/README.md
...many many times. I have been trying to get it to build with Gradle but for now, I'll just focus on Eclipse building until that works. I've imported BaseGameUtils project into my workspace as an Android library project. My game android project has two Android library dependencies: google-play-services_lib and BaseGameUtils. Everything in Eclipse is showing without any errors. When I build and run on a real device, I see an error that says -
[2014-10-27 20:39:25 - BaseGameUtils] Could not find BaseGameUtils.apk!
I don't know why it's even looking for BaseGameUtils.apk since it should be an Android library. That said, I'm not sure how an Android library is really handled so maybe it should be a .apk. In any case, I couldn't find any information on this bug and the error message doesn't give me much to work with. I've tried adjusting things in the Build Path but no luck. I did have to remove some redundant dependencies in my Build Path earlier since I was getting some kind of duplicate DEX error but I'm not sure that's related in any way to this. I am desperate for help, anyone have any idea?

Can you try this? It has to do with conflicting methods of specifying that a project is a library.
I found the source of the problem!
It turns out that "with the new library feature, you don't specify the
Android projects you depend on in the Java Build Path section of the
Properties. You do it in the Android section of the Properties".
So all I had to do is go the Application Project's Properties, hit the
Projects tab, select my own library project and click the Remove
button. That's it. No more problem.
In Eclipse Java EE select the project Properties, then select Project
References, then check the FacebookSDK (see screen capture)
From: Android Eclipse - Could not find *.apk
If that doesn't help, you may want to double check that you selected "Is Library" in BaseGameUtils.
Also, when you hit "Run" in Eclipse, are you running your application and not BaseGameUtils?

Please would you check that BaseGameUtils has "is library" checked and that your application project DOES NOT have "is library" checked.
If this is correct, then please would you review the following in detail (especially as regards checking and unchecking "is library" ) :
Android Eclipse - Could not find *.apk
I presume that the DEX error related to two or more versions of the same lib. What is the specific GameHelper error ?
As a general point, I find it productive to get a sample project working first to ensure that I have got the environment working correctly before I start integrating game services into my own projects. If you have been changing the build path then it may be quicker to start from scratch and get a sample working. I have followed those instructions in the past and they are accurate.

Android project suddenly full of errors because of different supporting librarys

So i wanted to add a facebook SDK to my android projects, the outcome was this:
I've decided to "undo" changes first so i removed the facebook library from my project
after:
The error is "R cannot be resolved", if im importing android's R it wont recognise the layouts anymore
for example:
My libs are:
I've tried removing support v4/v13 but neither helped. Im clueless, please help.

Copy/Paste the same latest v4 library in all the projects,

SLF4J.properties make it work in android

I am using SLF4J in various java projects, and works great. However I am trying it on android, and I can not make it see the properties file.
According to their instructions, (https://github.com/interdroid/slf4android) I have placed my SLF4J.properties in src/org/slf4j
and have set:
default.log.level=warn
I am checking \bin\classes\org\slf4j, and my file is there.
However I still get my debug log messages. Any ideas?

Found it.
Was using version slf4j-android-1.6.1-RC1.jar
and apparently it is working as described in version 1.6.2 which I compiled from github.

Android - cannot use external library

I was asked to make a project work in Android and I am a complete noob in this aspect and, well... things are not working...
I have created a little code in Java which uses libraries - this code works perfectly. I am now trying to make this code work on Android but I have problems...
It seems I cannot use any element from the libraries I imported to my Android project. The project loads on the phone perfectly fine when no instance of the library is created, but when I make use of the library the app crashed and I get errors.

Here is what the project package looks like

The part with the arrow is what I think makes the program crashed. When I remove this line, everything works fine.
I checked online about problems with Android and external libraries but I could not understand everything... Could you help me pinpoint exactly what is wrong and how to solve this?
Thanks!

I got this issue when I first started android development.
Key to this is to the external library seems to require them being another android project itself, instead of java project. After creating this android project, right click on the "external project" and choose properties. Under Android Tab, there should be something to check to denote that it is a library instead of application. After doing this, the linking is quite similar to how we link normal java projects to external java library

If you are using eclipse, than just create a "libs" folder in project root and drop your external libraries there.
Alternatively you Right-click on the jar file > build path > add to build path

Third party library troubles on LayerType attribute even after building it on Android 3.2

So, I coded my entire app in Android 4.0.3. I used AmbilWarna color picker. Then I got this requirement to reduce the SDK requirement for Android 2.3. This is the point when EVERYTHING was working fine and superb
I have downgraded teh minimum SDK requirement. Everything runs fine except as soon as I include Ambil Warna as a library on my project, I start getting the error everywhere R is used, Saying that R cannot be resolved to a variable.
Upon a loot on the Console, this is what seems to be the real cause of the problem:
AmbilWarna\res\layout\ambilwarna_dialog.xml:18: error: No resource identifier found for attribute 'layerType' in package 'android'
I have set the Android SDK to 3.2 for AmbilWarna library project and on my project its at 2.3
Does anyone have any idea?

this is regarding this: http://developer.android.com/reference/android/view/View.html#attr_android:layerType
you are just trying to use a property for android that is not available on that api of the layout parser.
I just checked out the colorpicker code you are trying to use, and it's project.properties says it's written for target API-17 (android 4.2) and i'm tryng to compile it for API-10 (android 2.3.3)
simply remove those parts.
my diff
--- a/AmbilWarna/res/layout/ambilwarna_dialog.xml
+++ b/AmbilWarna/res/layout/ambilwarna_dialog.xml
## -19,7 +19,7 ##
android:id="#+id/ambilwarna_viewSatBri"
android:layout_width="#dimen/ambilwarna_hsvWidth"
android:layout_height="#dimen/ambilwarna_hsvHeight"
- android:layerType="software" />
+ />
and hope it's not mentioned in the code :)

I've had a lot of troubles too with my external libraries. What usually helped are one of these or multiple steps of these connected:
Delete ALL R.java imports in your Classes (there must not be any of them)
In Eclipse: Source => "Clean Up"
In Eclipse: Project => "Clean..." (This will rebuild your project from scratch and therefore regenerate your R.java)
Manually delete all R.java and save (located in /gen/)
Delete your external library project and readd it.
Step 3 usually did the job for me.
Also be aware that your minSdkVersion and targetSdkVersion fit to your library project (and the guidelines which are included)

I had the same problem, I thought I could just build and include the third party jar file and bring this over to my project - this resulted in the same problem as you - AmbilWarna\res\layout\ambilwarna_dialog.xml error: No resource identifier found for attribute 'layerType'.
To fix it I copied over the source files and all resources into my project (images/layouts etc etc), hey presto it worked.
Thanks http://code.google.com/p/android-color-picker/ for a nice clean easy to use colour picker!!
