I'm making a game where I'm using Google Play Services. I recently switched from eclipse to Android Studio (now running 0.8.14). In android studio I added a "Google Play Services Activity" and had my game class extend that class. I left the services class without modification. The project compiles and runs just fine but the IDE is filled with errors because it "cannot resolve symbol 'common'" and "cannot resolve symbol 'games'"
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.games.Games;
Any ideas on why this is and how to fix it?
I have attempted to reimport my project after deleting all .iml files and the .idea folder without result.
[EDIT]
As per request I'm adding a screenshot of the errors:
[EDIT 2]
I've kept searching for solutions and while I have not found any, I now have a screenshot that may be a bit more helpful.
As you can see, the com.google.android.gms package seems to be missing the common and games package.
I have tried updated gradle, tried using JDK 1.7 instead of 1.8 and attempted syncing with gradle multiple times. I will keep searching for an answer but if you have experienced this before, please feel free to help me and others out.
Add this to your build.gradle
dependencies {
compile 'com.google.android.gms:play-services:5.0.89'
}
Finally I found the real problem. Apparantly, my project was contained in a folder that ended with an exclamation mark. (myProjectName!) This caused Android studio to fail in finding certain imports.
Solution: I renamed my project from myProjectName! to myProjectName and moved the whole project to a new folder without the trailing exclamation mark. This seems to have fixed everything.
Firstly, I have seen several question related to this issue but it seems like those questions might be some steps ahead of my understanding.
I am fairly new to java and consider myself as a self learning beginner. Mostly I face this problem where I do an import. I need it because that import is linked with the use of some really nice and powerful function(s), but always fail if import does not work and end up not using that.
The message is, e.g. "The import com.google can not be resolved".
I have been using eclipse in Ubuntu.
After trying some of the given solutions without being able to view them in the proper context, I already have messed up my eclipse environment and the trouble is still there.
Can anybody kindly show me the complete steps of doing these imports successfully in eclipse for java?
For using 3rd party jars you need to add the jars in the build path.
Follow the following step
right click project
click build path
click libraries tab
then add external jar
Now give the path of the jar location
i imported project that alredy works using SVN in eclipse , i needed to gain knowledge about that one, but unfortunetly i can't even build it. Whenever i build it i get multiple errors that are caused by
The import XXX.bl.* cannot be resolved
There are around 20 imports but only the ones from XXX.bl.* dont work. I will type you what i already tried to do:
Project -> Clean..
Adding XXX.bl in build path
Deleting and adding this imports
Changing to Java 1.6
Delete/Add JRE Library and adding Alternate JRE's
Ticking in Project Facets Java and Utility Mode (for no reason i read somewhere about it)
importing by clicking on "errored" viarable/class "import XXX.bl.*". Problem was solved but only until i Re-build/Clean project.
Closing projects, cleaning, open projects, cleaning
The weirdest thing is that when i type XXX.bl. and then click CTRL + Space it actually autofill this imports with correct names.
Im using JDK (Java EE 6 SDK Update 1 (with JDK 6 U23)).
I spent alot of time in order to search for a fix but nothing helpt so i figure out meaby if i create question here by myself and inform you what i already did you will be able to help me somehow.
Sorry for my pretty bad english, and thanks in advance!
codes are in 'sync', imports are in XXX.bl
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).
I recently figured out how to add the Jung libraries to eclipse, but now I ran into a new problem. I'm using the Jung tutorial and I can't seem to run the first tutorial, because the Eclipse IDE is saying that the .DIRECTED ,in the code, cannot be resolved or is not a field. How do I fix this?
edit: Yes, using that package worked! However, I'm surprised that the Eclipse IDE did not offer to import the package for me. Is this unusual?
Make sure to include all the required JUNG2 libraries into your Eclipse project. When you do that, Eclipse will give a few suggestions after you right-click on those yellow-underlined words. Choose the one(s) related to JUNG2 to remove the warning(s).
EgeType.DIRECTED must be imported from edu.uci.ics.jung.graph.util.EdgeType package which is under jung-graph-impl-2.0.1.jar
