After I left my Computer in standby, Eclipse (Android SDK Plugin) told me that it cannot save the project (because my NAS has to start up). But then I saw the project structure was failed like you can see here. Before it was like this (example from another project). I tried restarting Eclipse and importing the project again. How can I change it back?
Give a try these steps from menu option:
Project > Clean
once its done build the project
Project > Build All
Hope it fixes your problem.

I had an working Android project on Eclipse Mars and I wanted to add a Maven dependency. I followed some tutorials and successfully converted the project into a Maven project by using "Install New Software" for m2e, "Eclipse Marketplace" for android-m2e.
Now, I wanted to RUN the project, but all of a sudden, "run as Android Application" setting has been removed. When I tried to run as saved configuration (android application), it says "myprojectname is not an Android Project!".
I'm trying to make this work but for the whole day I'm stuck and can't figure it out :( I wish I committed the change right before I did this ..
Thank you in advance.
Solved it by myself, but I'm leaving this thread to people who might encounter similar problem.
What I did
removed both m2e and android-m2e from eclipse.
removed the project from Project Explorer in eclipse (IMPORTANT: DO NOT SELECT "DELETE PROJECT CONTENTS ON DISK(CANNOT BE UNDONE)" UNLESS YOU MEANT TO DO IT)
File->New..->Other->Android->Android Project from Existing Code -> select your project
Now I have my project generating "gen" correctly.
Hope this solves someone's problem.
When I started up my project this morning it randomly gave me a message saying Gradle project sync failed. Basic Functionality(eg. editing, debugging) will not work properly. in Android Studio. I looked at other answers that people had put up for this problem but they haven't been working. I invalidated my chaches/restarted my project but no luck. I also deleted my .gradle folder from my project folder and still no luck. If any of you guys could help me that would be awesome! This didn't happen yesterday when I was working on the project or anything, I wonder why its happening now. Oh yea it also says this as a gradle message: Error:C:\Users\Dave\.gradle\caches\2.2.1\scripts\settings_ad4t0wp5ikihzl1y1o83b5sbw\SettingsScript\buildscript\cache.properties (The system cannot find the file specified) :
Thanks again for anyone who reads this/ can help!
There is a file - "cache.properties" that gradle creates for you, upon first time inception of any project. The path for this file is "~Home_Directory\.gradle\2.2.1\taskArtifacts". You may find this path in your home directory. So basically, this file - "cache.properties" is missing from the "taskArtifacts" folder.
One of the solution that worked for me is to copy file - "cache.properties" from any test project of yours to this project that's currently experiencing an issue.

I had to choose using the Default Gradle Wrapper instead of local.
<< SETTINGS -->/ BUILD TOOLS --> Gradle --> radio button switch... >>
It has helped me to fix the same problem.
I had experience similar sync failed problem with gradle based android project (in Android Studio 1.1.0). I solved this problem without deleting .gradle from my user directory,
steps I followed was
Go to File -> Settings -> Compiler(Gradle Based Android Project)
Change VM options to -Xmx512m -XX:MaxPermSize=512m.
Click Apply -> OK and then tap on Try Again option in sync failed message to clean build the project.
Works like charm!!
UPDATE - 1 : For Android Studio 1.3, Compiler option mentioned in above Step-1 is present inside tab Build, Execution, Deployment.
I had faced similar kind of problem earlier!
But don`t know after rebuild the project and cleaning it, it worked normally.
Invalidate dependency cache by running
gradle clean build --refresh-dependencies
from project root and then re-import your project. Worked for me once.
May be you have put Android Studio into offline mode. To fix it, go to Preferences -> Gradle and ensure that the "Offline work" checkbox is not checked.
Than do
File -> Invalidate caches / Restart
Shutdown Android Studio
Rename/remove .gradle folder in the user home directory
Restart Android Studio let it download all the Gradle stuff it needs
android studio 0.4.2: Gradle project sync failed error

I am working on SIP application and using Linphone Library.
I am trying to make and run the build on the device but getting few issues
I have setup the Android SDK and NDK set up on my Mac.
Now when i copy the repo via Terminal using command
$ git clone git://git.linphone.org/linphone-android.git --recursive
And than to Makefile ran this code:
$make
and Then it show's Build Successfull.
Now i need to import this project into Eclipse and when i do this imported project (folder named "linphone-adroid") into my Eclipse it shows me alot's of projects i am confused which one should i use and if i choose all of them then it gives me lot's of errors in other's (Shown in image below)
liblinphone-android --> Ran this on Device runs fine but when i call the numbers it changes it's view and shows duration 0:00 and does not calls the numbers then i have to press hang off button to dismiss the call. (Not able to make call's)
Please suggest me how should i import this project into my eclipse and what else scripts i need to run on the terminal to make it run.
So far what i have did is right or wrong?
Yes , it worked finally.
After build using "make" command.I installed in my device using "make install". Also generated sdk using "make linphone-sdk"
And then simply imported in eclispe just like normal android project.
Without any error it worked. - thank god.
In windows8 cygwin created many issues, so i did build the code using "make" command in MAC. And then simply imported in windows eclipse. (some admin permission issue in MAC)
Note: android-ndk-R9c was failed my build. So then i tried with android-ndk-R9 without additional toolchain it worked great. Android-ndk old versions available at
(http://page2rss.com/0dc3a880ab1762303011d69d18408917).
after building the library you have to import it in eclipse
File -> New -> Other... -> Android -> Android Project from Existing Code -> Browse_your_project
Now open your application (Project which have activity) and assign linphone library which you have earlier loaded....
Right click on your project -> select Android tab from left hand side -> from the bottom library section, click on "Add..." -> you will see the listed library which you have in your eclipse workspace -> select correct one -> click "OK" -> now refresh and clean the project -> build and try to run
check complete guide on linphone android on coders hub.
As suggested by #bhavana
I was doing wrong while importing the linphone-android project into my eclipse.
The correct process is explained below-
Importing into Eclipse :
After i have made the build then now i just need to import the project into eclipse.
Step1: Go to eclipse click on File Menu then Import then select
Existing Android Code into Workspace
Hit Next and Browse to the linphone-android project folder
And Only tick linohone-android folder and Leave copy project into workspace untick
Like the below image:
And hit finish.
Now i right clicked on "linphone-android" (project name) and go to Properties and Java Build Path and then Order and Export and then reorder them as my image below and untick gcm.jar
Hit OK
And Boom No errors
Now just run it on device or emulator. (Cross check minimum target SDK matches with the device or emulator.)
The above steps worked fine for me.
I am just starting to learn Libgdx, and am in the process of importing the 4 projects[desktop, main java game, android, html] into Eclipse Juno. I have not added any lines of code, just trying to get them to run on the different platforms.
It runs fine on the desktop version, but when I tried to run it in the Android emulator I get the error. Cannot find mygdxgame.apk!
I realized that my gen folder is completely empty, there is no R.java for the project. I have tried a number of things to make this work, but none of it is working. I am listing the things I have tried so far, and the hopefully the reason why I am asking this repeatedly asked question.
Project > Clean
Package Explorer [right click on my project] > Android Tools > Fix Project Issues
Deleted gen folder and Project > Clean
Restarted Eclipse
Deleted the project and Imported it again
Set Compiler Compliance Level to 1.6 for both main java game and Android project
Added a dummy XML to the android project and tried clean, and deleted it
Unchecked and rechecked Build Automatically
Checked my target-sdk in project.properties and made sure it is the same Project Properties -> Android and in my Manifest.xml
[Right click on project] > Properties > Java Build Path > Source tab, Removed mygdxgame/gen folder and then added it again
Made sure Project Properties > Android > Is Library is unchecked
Nothing has worked so far. My gen folder is still empty and I am unable to run the Android project because of the same error. Cannot find mygdxgame.apk!
What else can I do to fix this? In case this is answered I would appreciate someone giving me a link to the solution, as I have been pouring through SO and Google in general for nearly 2 hours now, with no success.

What happened to me a few days ago:
1.- I got the SDK Tools 22 update and I installed it, no other update appeared in my sdk manager... so I closed it.
2.- Then I got that "NO APK" error and tried every answer I could find.
3.- I opened SDK manager again, and I noted SDK Platform Tools also got an update and there was a new one: SDK Build Tools. Both of them didn't show up when I first updated the SDK Tools.. so.
ANSWER:
Open SDK Manager and check if your SDK Tools, SDK Platform Tools, SDK Build Tools are updated :)
On your build path, you should have a reference to the main project, under Projects tab of Java Build Path. Under Libraries, you should have gdx-backend-android.jar and gdx.jar along with Android not being a library.
Please check if Android is set as a library. If so, uncheck it. To do that, right click on the project and then select Properties. Choose Android on the left panel of the new window. Uncheck Is Library if checked.
Here's something might help-
Unable to run Android app, Could not find .apk issue in eclipse
I would take alook at your buildpath if all libs are correct. If it's a projekt from an other computer the libs are often at different places so you need to correct those manual. If they are not correct the android projekt do not generate your R. class and so on. So do rightclick on the core projekt -> Buidl Path -> Configure Build Path. Now take a look at the libs if all are there. I had the same issue with the android 15 apk so i need to add it manual. The clean or such do not fix such because eclipse can't know where you have all your libs.
If you really dont get it run i would recoment to use the setup ui of libgdx. It does noramlly handle all imports and so on for you. You can also use it to update your current projekt and so on.
Else i would read the guide for Manual Project Setup of Libgdx.
Libgdx setup Guide
I hope this does fix it.
I am using Eclipse 3.5 for Jave EE Developers. Plugins installed include: Android Development Tools, Adobe Flash Builder 4, PDT, PyDev. I have problem with running the application I built.
I can start a new project, add a button, and run it on an AVD. Then I add another button, try to run it on AVD, and Eclipse says 1) gen folder is missing, 2) there are errors with build path.
I can get ride of the first error by simply refreshing the project in the left pane, but the second error always sticks around. I searched online and on StackOverflow here and here, although several people have the same problem, there is no definite solution I can find.
Can somebody who fixed this problem successfully tell me how?
try this
a)Delete your project from Eclipse (i
said ONLY from Eclipse, so uncheck
option: Delete project contents on
disk)
b) import your project to Eclipse:
file > Import > Existing Projects into
Workspace (Look for your project
previously deleted from Eclipse) >
Finish
