Sort of a amateur question, but i have been trying to import facebook sdk in to eclipse so that later i can use it as a library in another project. At first i was faced with a lot of errors, but i solved a lot of them by figuring out how to add the external libraries. But only a few issues which are still left are:
Error on Import com.facebook.R (cannot be resolved)
Error on R.style.com_facebook_loginview_default_style (R cannot be resolved)
Need help, as i could not find any thing regarding this issue. How to make this go away.
It means the facebook SDK project cannot generate the R.java file(check the gen folder in your project)
Usually it's your project API version is not right, or you could post your error message(look at console window and post here what it says)

but still I get errors in splashactivity project
it shows error as R cannot be resolved to a variable. ........
a spend whole day but i did't get anything please could someone help me
I would put this as a comment but don't have enough reputation yet. Errors in your XML layouts can lead to this error (R does not get built if there are errors in the layouts), so check there first. If everything is good there, check your imports in the file you have the errors in. You might have a bad import; you should have something like:
import <package_name>.R;
If that is not referencing your current project you will have a problem.
Also, make sure you do a Project > Clean.
I have been using Eclipse for about 6 months now, and I noticed that I rarely can import someone else's project into Eclipse. I get so many errors in many files. For example, I tried to import a friend's project that I know works just fine, but I get a lot of "R" errors, like Eclipse can't recognize "R" as a field, and then other weird ones like ActionBarActivity is not recognized or an entire imports like android.support.v4.app.Fragment that visually are in the library but are not being recognized by Eclipse as being there, and I check them and they are definitely marked "Is library" and added properly to the project. Anyone know why this is or how to fix? It's frustrating because to learn, sometimes you need to see someone else's app run first, then look at their code, but you can't. Thanks in advance.
My usual way of importing a project is to do File -> Import -> General -> Existing Projects into Workspace. Also, I have tried cleaning the project, but it doesn't work.
try this File -> Import -> Android -> Existing Android Code into WorkSpace ->then browse-> select your project->make sure the checkBox"copy the project into workSpace" is marked
Check your Build Path. In the Android Section, try using some other API level click on Apply and after your project finishes with the building workspace, again revert back to the original API and click on OK.
Also check for any Build Path errors.
So thanks to the help of everyone of this post, and others on another post, the problem was finally fixed and took several steps.
Turns out that the ActionBarActivity error had a quick fix (hover over it, you get quick fix options) of importing the appcompat_v7 library. I never chose that before, because I thought it was already installed, hence the conflict with android-support-v4.jar (meaning there were doubles of that library), but I chose to import it anyway and that error went away.
But I discovered that android-support-v4.jar was actually a component of appcompat_v7, so that was causing the "Jar mismatch!" error in the console. So I deleted android-support-v4.jar from the libs folder, and the jar mismatch went away.
Lastly, my layout files were all not being recognized, even though I knew the variable names were all correct. So the error was from when I tried to refresh my imports in the very beginning of the problem (using shift+command+O), thinking it was an import problem (which it was), but at that time, refreshing did nothing. BUT... Eclipse took away import com.laurengariepy.android.gridimagesearch.R; and replaced it with android.R;, which is what was causing all the layout errors. So once I put that com.laurengariepy.android.gridimagesearch.R; back, then all errors went away.
So the take-away to this story, is be careful with Eclipse version 22.6. The auto-import of the appcompat_v7 library will cause a lot of trouble when you try to import other people's projects, because they were likely not created in an IDE with appcompat_v7 already there.
I'm trying to build Google's open-source Calendar app for Android (source here: https://github.com/android/platform_packages_apps_calendar), so that I may pick apart its code a little bit. When I import the freshly-cloned project into eclipse, I get a bunch of ____ cannot be resolved to a type errors. Looking closely at the types that aren't resolved, the root cause seems to be:
The import com.android.common cannot be resolved
The import com.android.ex cannot be resolved
I've been googling and I can't seem to figure out what's going on? I must be missing some library? I have everything in the Android SDK Manager installed, even the optional libraries. I've tried cleaning and fixing build path properties, etc. The errors remain.
Anyone have any idea what I can do to get this thing to compile?
I have managed to add almost all the required dependencies and now i got an almost-running version.
Kindly, check it out from here
You can also check the last commit, it contains all what i did to get this running version.
Have a nice day :)
I'm trying to get the Android LVL (App Licensing) setup to work with my software... and I cannot get it to import into Eclipse at all. The documentation says, "add the library folder to your workspace"... but it won't let me. I have rev. 2 downloaded... but when I try to import the project (from /android-sdk-macosx/extras/google/play_licensing/library) it shows up greyed-out in the projects list and won't import. Can someone please help me out here?
Just drag the sources into your project. The intention of the LVL is that you build your own sources and make changes (to try to thwart people that modify your binary by looking for LVL-specific bits).
I've downloaded the android source code for CallLog, Contacts, Dialing from here.
But now, when I try to import this package on Eclipse, imports like:
com.google,
com.android.internal.Telephony,
com.android.internal.R,
com.google.android.collect,
android.provider.ContactsContract.Intents.UI,
android.provider.ContactsContract.SearchSnippetColumns,
android.provider.ContactsContract.ProviderStatus,
android.provider.ContactsContract.ContactCounts,
android.content.IContentService,
android.provider.ContactsContract.Intents.UI
And many other imports, show errors saying it cannot be resolved.
So my question is, why it shows this errors? Why I cant implement it without this errors? I use the Google APIs, I've created the project from an existing source code, but I dont know why this happens.
If you're sure that you have set up the Android SDK correctly, you should try to 'clean' your Eclipse project.
This usually solves import related errors in Eclipse for me.
Try right clicking the solution / project in the project explorer and choose "fix" near the bottom.
