Tried to export working android project from eclipse. The screen is frozen at page "Export Android Application". "Next" button is grayed out. Same project runs fine on emulator and HTC as well. Please help.
Restart Eclipse but if that doesn't fix it, try the following:
Under the Project menu, choose Clean...
Click Clean All Projects then click on OK.
I sometimes find that Eclipse gets messed up. Cleaning all projects in my current workspace usually takes care of it.

I have been studying Android on Eclipse Mars for some time and i have been facing a constant problem everyday-the changes made in a folder/file are not recognized by some other folder/file. For example, if i create a new layout in the layout folder and then use it in the setContentView, it shows me an error ("layout-name cannot be resolved or is not a field). It works if i save the project,close it, and open it again, but this takes up a lot of time if i have more than one error, so the question-is there a way to save and refresh the project (without having to close it) so that the newly made files and folders are recognized by the java files?
Thank you.
You can refresh your project in Eclipse by right clicking on the project root folder in your Project Explorer and selecting "Refresh".
You may also want to consider checking if you have "auto build project" turned on. In your top toolbar go to Project -> Build Automatically.
If build automatically is turned off you will have to manually build your project, by Right Clicking on the project in your Project Explorer and selecting "Build Project".
However, I do agree with Pankaj Nimgade that Android Studio is likely a better entry point IDE for Android development.
Real advice: Switch to Android Studio as soon as you can. There you would sometimes have another problem called "sync" though. But it's a much better IDE and you are at least in line with Google.
on Eclipse, F5 should do the trick. Or right click your project and Refresh. Or Clean all projects. If you are still stuck, simply close Eclipse and run it again.
I was developing a simple app and eclipse says that i cannot run the app because there are errors. I try to find that error, but everything is perfect! Its a simple app(a counter)...
Please Help!

EDIT:
There is nothing wrong and it does not report any bug. When i click "RUN" it just says "Your project contain error(s), Please fix them before running your application".
Let's try to make a full clean of your project.
Right click your project name. Android Tools > Fix Project Properties. If you have multiple Library Projects linked to this project, follow the same step with them first.
Hit the top menu Project > Clean. Select the radio button Clean all projects and hit OK.
You should leave Eclipse doing its job (depending on the amount of projects and files, it may take a while). If this doesn't work, follow the same process, but as a third step, close Eclipse and restart it right after you hit the OK button. Eclipse is powerful, but a silly IDE sometimes.
If the problem is there after restarting, and you have some libraries attached, check inside the Project build paths (right click the project name, Project Properties > Java Build Path) have the proper JARs, only once, and before any Android Library
I followed googles instructions and exported a test project from Eclipse by using the
Export -> Generate Gradle build files
opened up Android Studio and imported. After getting my support libraries working properly my project would compile with out any errors. My problem started when I tried to run the app on my device. When ever I try to run the app it directs me to use an AVD, never giving me the option to select my device. I obliged, created a new AVD but to no avail only to get build failed error. (I'll add the exact error when I can) NOTE: I can see my device is connected by clicking on "(6)Android" and the bottom left of the screen. I do see all logcat messages in verbose. I added android:debuggable="true"to my manifest but still nothing.
Confused I created a new project directly from Android Studio, hit run and bingo,...it gave me the option to use my device to run it or an AVD. Selecting either results in a successful launch of the dummy "Hello World" app. I think it may have something to do with build variants as my imported project doesn't specify "debug" vs "release" while the Android Studio generated project does.
Anyone else experiencing this?
I found the answer to my own question. Bit of a double whammy. Before installing Android Studio I updated my SDK via Eclipse (as recommended/required by google). Turns out by doing so a few items in my current projects got disconnected. ie. build paths, dependencies, ect. (you now have to place external Jar's in the src/libs folder)
Here is what I did to fix it.
In Eclipse, Preferences -> Java Built Path ->"Order and Export" tab. Make sure items are selected
If you have external Jars, manually copy and paste the jar in the libs folder of the project. (I did this in my Finder)
confirm the project launches via Eclipse
If it runs, export the project again by "Generate Gradle build files" (confirm overwriting existing files, if any)
5.Open Android Studio and re-import the project. Again, confirming overwriting of any existing files.
6.Next to the run bottom at the top of the screen click on the drop down next to your project name. Click "Edit Configurations..." and select "show chooser dialog" if not already selected.
clicked ok to exit,..and PRESTO!!! I finally have a successful project migration.
Hope this saves someone else time.
Cheers!
Yeah i have experienced similar stuff on Eclipse, its quite buggy. Since Android studio is based on it i would expect everything. Still the best solution to everything is to reload project, refresh project or restart IDE.
I have a problem when launching a project from Eclipse in my Android Virtual Device.
I have multiple projects in Eclipse and when I run one of them by pressing right click on a project -> Run As -> Android Application it always run the samen project. (The first project I made in Eclipse)
Does somebody knows how I can fix this?
click in the folder on the project that you want to run, then click run.
Check If you have changed your manifest.xml accordingly. It once happened with me because i copied code from one manifest to the other.
set the path properly for the default activity
Last night when I'm developing an Android app using Eclipse, the computer suddenly out of order and showed a blue screen.
After restarting, open Eclipse, and when I continue the development, I found out that Eclipse will not show any error message even if I type anything wrong.
For example, I type $^&((^(*&$GFKGHlkgvfekigfe in the activity, Eclipse shows nothing, just like the code is correct LOL
How can I re-enable the auto debug function? Thanks.
Or try to run Eclipse in clean mode. Please see the following discussion: How to run eclipse in clean mode
Try cleaning your project. In Eclipse, select your root project folder in the project navigator, then go to Project > Clean... > OK. You can also clean all projects by selecting the Clean all projects radio button in the clean dialog.
You able to Automatic Build by
Go Eclipse project menu
Choose Build Automatically
