I know. Many similar questions. I have not found any answer that solves this one.
How do I get the Google Play Services lib to work in Eclipse 3.7.1 with Android SDK Tools 23.0.2?
Tried alot of combinations. First, to get the lib to import correctly. I've tried these methods beside the obvious flawed from Google. (I've also removed the write-protection from all files)
Copy the code to the workspace and use File --> import --> Android --> Used ex... then checked the COPY-box.
Copy the folder to another place and then import into the workspace and linking it.
Then in my project I added the meta-data-thing into my in androidmanifest.xml.
In my project I've clicked Properties --> Android --> In the lower panel I've added the Google Services Project that I've imported.
Now everything builds. (I've seen that many people have trouble with that.)
In properties, under the option Java Build Path the libraries are checked under the tab "Order and export".
The method I use in my main activity is
GooglePlayServicesUtil.isGooglePlayServicesAvailabl(..)...
When I run the application I get an exception, NoClassDefFoundError.
And for sure, the class is not in the APK. I've checked, but some other classes under from gms.internal exists?!
In my project under Android dependencies is the 1k output from the imported lib. Under Android private libraries is the full jar.
Update: Solved this by downloading the latest version of http://www.eclipse.org. (The update function didn't find anything).

guys, with my friend started working on a school project - developing a java app for android. He started it, now it's my turn to do my job, so i got the code he already has, set up Android SDK for Eclipse and downloaded all the neccessary files and packages, but it still gives me errors and I can't even run the project.
One of the errors (the main one, I think) is that it can't import android.support.v7.app.ActionBarActivity
If anyone knows what can I do (I've tried all kinds of solutions from the internet, but none work) I would be very grateful.
Here is a screenshot of the code

See if you have imported the ActionBar project to your Eclipse workspace, also, right click on your project->properties->android and check that you have referenced/linked the ActionBar project there.
If you are using a repository without the proper ignore files it is possible that you have imported your partners configurations and then have the references to the auxiliary projects broken (you just need to update that).
Hope it helps.
android.support.v7.app.ActionBarActivity is a support library. This allows older versions of Android (before native support for an action bar was available) to use the action bar.
Since you are having difficulty importing it, I'd assume you do not have the support library installed.
Full instructions are available here:
http://developer.android.com/tools/support-library/setup.html
A snippet for adding support libraries to Eclipse:
Make sure you have downloaded the Android Support Library using the SDK Manager.
Create a libs/ directory in the root of your application project.
Copy the JAR file from your Android SDK installation directory (e.g., /extras/android/support/v4/android-support-v4.jar) into your application's project libs/ directory.
Right click the JAR file and select Build Path > Add to Build Path.
First of all, I realise that similar questions have been posted a lot here. But I've been through all of the answers I can find to similar problems, and nothing has worked yet, so was wondering if someone could help me.
I'm trying to develop a simple chat app with an Android client and a server app sitting running on my laptop. This includes a regular Java "common" project that holds the class that is used to pass messages via the socket.
First I tried to reference the "common" project in the Android project, but after a bit of reading abandoned that idea.
Now I have exported the jar file for the common project, and imported it into my Android project by copying it into the "libs" folder, and then selecting Build Path > Add To Build Path. I have also gone to Properties > Java Build Path > Order and Export and checked the library and moved it to the top of the order.
I have also moved the "gen" project above the "src" one in that build order.
Android Private Libraries is also checked. Everything is checked.
When I debug as an Android Application to my Samsung S3, I see a "Could not find class error" in logcat when advancing to the Activity that contains a reference to a class in the "common" project. Stepping through to the point where a class in the "common" project is referenced then causes a ClassNotFoundException to be thrown.
If I try to put the name of the library in the Android Manifest, like:
<uses-library android:name="com.johndarv.chatproj.common" />
I get:
Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY
Please check logcat output for more details.
Launch canceled!
Upon trying to install.
I have the following versions:
Eclipse Standard SDK 2.0.0
Android SDK 22.3
Android project is compiled with Android 4.2.2.
Any help would be much appreciated! If I can give any more info that would be useful, please ask!
The uses-library tag means that your app expects the library to be available on the system. This is to prevent installation on devices which do not have some expected third-party software installed. Consider phone manufacturer who ships his devices with some specific api.
So this is not your case. Forget about this tag this time.
And as to your problem. The jar is not exported into the apk.
Ensure in Project Settings > Java Build Path > Order and Export that the library jar is checked to be exported.
If you put a jar into /libs dir of android project it is automatically added to the build path. You do not need to do this manually (as you did). Then you can see it (this jar) under Android Libraries entry in under Project Settings > Java Build Path > Libraries. This entry is also checked as exported (by default in android project) in Order and Export tab.
Maybe your problm occurs due to the fact that the jar is actually exported twice (once manually and once as private library). Just remove manually added entry from build path. You will have it added once - but to be honest I do not expect this caused the problem. But for sure the problem is in your project settings. Maybe paste a screenshot with Java Build Path > Order and Export and Java Build Path > Libraries.
I managed to solve this by deleting the common project and then creating a new Java project with "Use execution environment" set to Java SE 1.6. And rewriting (copy-pasting) the old classes.
There must have been something wrong with my previous project, and looks like it was the Java version used to compile. I had tried to set the compliance version to 1.6 on the old project. In any case, creating a whole new 1.6 project, pasting the classes in, re-exporting, and copying into my Android project did the trick.
Thanks to everyone who tried to answer this for your help. Hope someone finds the above useful one day!
I am trying to add Support Library v7 to my clean android project as support library (with resources). I followed every instruction here: http://developer.android.com/tools/support-library/setup.html#download and android.support.v7.* package is not visible in my main project.
Here is library reference in main project:
Support library project tree:
Support library project build path:
And finally, my main project tree
I don't see any errors in Problems tab, app compiles and runs normally but i cannot import android.support.v7 package which apparently isn't in build path in main project. I went through instruction twice in clean projects/workspace. I cleaned project, restarted Eclipse and nothing... All resources from library project are unreachable too.
Thanks in advance :)
Copy the library project to the folder where your android project is.
Select File > Import.
Select Existing Android Code Into Workspace and click Next.
Browse and import the same to eclipse
Once the library project is imported you can refer the same in your android project.
This is similar to setting up google play services in eclipse described here. Check the 4th step
http://developer.android.com/google/play-services/setup.html
It looks like android-support-v7-appcompat.jar is missing from your libs folder.
When you download the Android Support Library through the Android SDK Manager it makes the support .jar files you need available under {SDK Location}\extra\android\support.
To use the v7 files, copy these to your project's /libs folder.
android-support-v4.jar
android-support-v7-appcompat.jar
android-support-v7-gridlayout.jar (*if needed)
android-support-v7-mediarouter.jar (*if needed)
Typical gotchas (this looks OK in your setup):
Make sure the min SDK is at least API 7
Make sure the project target build is at least API 17
For more information about using the support V7 package (including running the v7 samples) can be found at the RHM Guide to Android Support Lib.
The issue seems to be in Absolute path in case of Windows base machine. I faced the issue of referencing support libraries When I moved Eclipse and related libraries to different drive than where the project was.
Copy paste the libraries to folder on same derive in a way that it can pick by relative path.
..\androidCommonlib\appcompat
android.library
I'm using ORMLite on our Android app, and I've previously set up an ormlite_config.txt as described in the documentation
http://ormlite.com/docs/table-config
I've now updated my classes, so I need to regenerate the file, but I can no longer get my DatabaseConfigUtil to run in Eclipse. I've set the Run Configuration as described in the documentation, choosing the local JRE and removing the Android bootstrap entry from the Classpath tab. But I just get a whole bunch of java.lang.NoClassDefFoundError for all the Android-derived classes in my project.
I've obviously changed something since I originally generated the ormlite_config.txt file, as I didn't have any problems before, but I can't see what I've done to break everything.
Can somebody tell me exactly what I should have in my Classpath / source tabs?
In the end the instructions in the documentation were all that was required, there was just a pair of bugs introduced in 4.43 that prevented it working as it should. These have now been fixed, and will presumably be in the next version. See https://groups.google.com/forum/?fromgroups=#!topic/ormlite-android/nBuQTVpCs0g
I ran into this exact problem and found out a solution myself.
I think the problem came from Google's ADT plugin. Since the plugin manages the Android libraries as private libraries, ORMLite Util cannot find the Android related classes in the project's build path.
The solution is to manually add the android.jar from your android sdk folder (in my case it's C:\android-sdk\platforms\android-18) into the build path as an external jar.
Hope it helps.
You have to remove the Android Lib from Bootrap Entries!
Do as follows:
Project > Properties > Run/Debug Settings
Select the class you want to compile and click edit
open tab "classpath" and remove Android Lib from Bootstrap Entries
I'm trying to get an app to compile that uses the android-support-v4.jar and the Fragmentation classes it contains, but I keep getting messages whenever I try to compile that there are errors in the code. All of the errors have to do with different Fragmentation classes that are in the .JAR. I have tried ctrl-clicking the project folder and then selecting Android Tools -> Add Compatibility Library and I keep getting this error:
[2011-12-20 11:55:31 - Android Compatibility JAR not found:]
/Applications/eclipse/Eclipse.app/Contents/MacOS/v4/android-support-v4.jar
Why would it be looking for the .JAR in Eclipse's Package Contents? I've gone into the project properties and went to the Java Build Path, and imported the .JAR from the MainActivity/libs folder, that didn't work, and then I tried to import it from my SDK directory, and that didn't work. I've fixed the project properties and cleaned and built it countless times, I've restarted Eclipse, my computer, re-downloaded and installed Eclipse, the Android SDK's and ADT and still nothing. I am completely stumped.
Edit
I've gone through the build path and imported the .JAR from both the MainActivity/libs and my SDK directory. For the hell of it I added the .JAR in the directory that keeps appearing in the errors and that hasn't worked. What's making Eclipse look for it in it's Application Package Contents?
Update
So after tinkering the project contents aren't showing any errors but the MainActivity folder still says that there is one and I still can't compile.
Like nyah:
Revision
So I think the question may be "Why is Eclipse looking for the .JAR in the Eclipse Application's package contents instead of the libs directory of the project or the Android SDK directory that I used to import it as an external .JAR?"
Update #2
I am only getting one error now after tinkering, it's on this method:
#Override
public MenuItem setOnActionExpandListener(OnActionExpandListener onActionExpandListener) {
// Noop
return this;
}
The Quick Fix says that I should delete the #Override annotation but that method must override a super class method.
These are the errors that it shows:
Multiple markers at this line
- The method setOnActionExpandListener(MenuItem.OnActionExpandListener) of type SimpleMenuItem must override a superclass method
- implements android.view.MenuItem.setOnActionExpandListener
Looks like it is looking for jar here :/Applications/eclipse/Eclipse.app/Contents/MacOS/v4/android-support-v4.jar
android-support-v4.jar is found in <sdk>/extras/android/compatibility/v4
Please make sure you add this as an external jar in the java build path
I could solve this problem by
1- delete "android-support-v4.jar" from lib
2- right click on the name of the project choose "Android Tools" and "Add Support Library"
If this is still not solved:
Like already said, in Eclipse go to your Project Properties > Java Build Path > Libs > Add External and get the one from the adk directory.
Also set up Java 1.6 as your default compile version if you already haven't. This should solve the Override Errors you described.
It turns out that my Debug Certificate had expired so I just needed to delete ~/.android/debug.keystore and restart Eclipse and everything worked.
I realize that this question has been answered, but this is a known issue that is supposed to be fixed in the ADT-17 plugin release according to comment 9 here: http://code.google.com/p/android/issues/detail?id=21488
In addition, people who have this problem can copy the compatibility JAR to the location it says it can't find it. Clearly it's looking in the wrong place (since it's checking the Eclipse directory rather than the android-sdk directory), so the simple fix, for now, is simply to put the package where it wants to find it, even though it doesn't belong.
For me it was as simple as copying the v4 directory within C:/android-sdk/extras/android/support/ into the C:/eclipse/ directory.
I had the same problem running in Ubuntu. Go to Tools->Options.
Check Force https://... to http://
Open Android SDK Manager. Check Extras->Android Support Library.
Something similar happened to me. At the top of MainActivity.java I had the next imports giving errors:
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
In each of the lines on the left they had the light bulb making some suggestions. If you click on it, one of the options will be "Fix project setup". You then will be able to choose between several options for fixing the imports, you should choose the one that specifies the android-support-v4.jar.
Right click on ur project --> select android tools --> select add support library and simply installed the supporting libraries.
Do you try not to do Android Tools -> Add Compatibility Library, and only add the jar in java build path library?.
I use this jar library of this way and it works without any problem.
I had the same problem.
Under the project properties:Java Build Path:Order and Export tab, the box next to android-support-v4.jar wasn't checked. I checked the box, and the error went away.
Another caveat was running Android SDK Manager in Windows 7 without administrator privileges. It would try to install support package, but would always fail, and the actual package never got downloaded to
C:\Program Files (x86)\Android\android-sdk\extras\android\support\v4\android-support-v4.jar
Solution: Make sure that you enter the same API for "Target SDK" and "Compile with" during Android project creation (or in the Manifest file once created).
