My app was working and I did not change a single thing in the source code.
Eclipse updated and now when I try to run the app it doesn't open and that error messages shows up where you have to force close it. It doesn't even have the other option of wait like I have seen before.
I know this is very little information but that is all I have and that is why I am so frustrated. I reverted back ... I reinstalled eclipse and the android plugin. I tested Hello World and that worked fine. I am so lost. This really sucks. Please help.
If you have third-party JARs in your project, then I experienced the same thing this morning. You can verify this (poor choice of words, I know) if your LogCat shows a VerifyError with no helpful information as the cause of the problem.
The solution that worked for me was to check these items in Project Properties > Java Build Path > Order and Export.
If this doesn't help, can you post the LogCat output?
I've run into the same issue whether I have 3rd party JARs or not. As sastraxi says, when this is a result of a 3rd party JAR, fixing the build path often fixes things. I often find the most effective solution, however, is to click Project -> Clean. This realigns all resources and rebuilds the project according to whatever the new SDK's rules.
Hope this helps,

I have an Android Studio (Bumblebee 2021.1.1) project, composed of a main app plus two imported libraries, one Java and one native, developed by me.
At a certain point in time - I cannot recall any event related to this, - the compiler has stopped recognizing the code changes.
If I write something random (e.g. my name, or "aaaaa") within a code that has thus far compiled successfully , the IDE marks this in red as error, however, when I press Ctrl+F9 ("Make Project"), the compiler does not detect any change in code and ends with "BUILD SUCCESSFUL". This happens also when I explicitly save the modified code. The only way I have to make the compiler detect the change is to launch "Rebuild Project". I have tried all the solutions proposed in Android communities (delete ".idea" and ".gradle" folders, invalidate cache, etc.), to no avail. To be noted that I have other projects on the same PC with the same Android Studio instance, but the always-successful-build only happens with the project mentioned above. Can anybody please help me? This is very frustrating, because, even for a tiny code modification, I have to rebuild all, which is very time consuming. Thank you very much.
Hello there I seriously need a help, I am a python programmer who just have started learning flutter, I have been sitting on one single error for 12 hours now.
I have tried every possible solution on the internet. I have re-installed android studio too, tried to fix xml files too. I am attaching the error below and a screenshot of my build.gradle too, please ask for more if need.
I also get this issue and in my case I found two solutions. First, rebuild the project or you can also try clean project. Second if your project is not big, you creat another fresh project and copy all codes from previous project to this new one and third but not in the list, go to settings and search gradle and then select the latest version of gradle or download it after finishing it restart the android studio with "run as administrator ". Hope it will works.
I just managed to successfully install Eclipse and even set up an AVD.
To get started I created a project, but there are two things I wondered about.
Eclipse created a folder appcombat_v7 above my actual project. I've never seen this happen before (like in youtube-videos, or so)
The other thing is, when I wanted to run my project on my AVD it said there was an error that I have to fix first. Eclipse told me AndroidManifest.xml is missing. It really was, I cleaned the project, that solved the issue. I wonder why it was missing though. Is that normal?
Thanks in advance. Philip
This appcombat_v7 is something that comes with the latest version of SDK, this happedned with my workspace also when i updated to the SDK.
Also it automatically adds the fragment part.
I am developing an Android App in which I use lot of JNI Code.. Recently (from last 2-3 days I am really annoyed by surprise behavior of eclipse) it shows me vague errors as soon as I open my .c file... However errors disappear if I close and reopen the project. See the secreen shot attached. Is it because I just update my eclipse installation (just update of eclipse plugins, I am still on my old Indigo)...
Is it an eclibse bug or something wrong with my setup ?
Solved ????
I tried everything but noting could change the behavior of eclipse.. By this time I knew that I have certainly messed with the project Settings by mistake, since eclipse was behaving well in other projects of same workspace. So I recreated the project manually and finally that solved myproblem...Though the Question is still open for valuable answers I think soon I will get some good answers..
UPDATE
Even eclipse 4.2 release also has this problem.. #frustrating
I found that deleting the project and than reimporting the project to workspace solves the problem. However I also came to knew that deleting .cproject file from the project tree can also fix this problem. Fixing the NDK path (Window -> Preferences -> Android-> NDK) in Eclipse preferences may also solve the problem.
Solution 2 Which may work in few cases...
Right click on the project.
Select Android Tools -> Fix Project Properties
Related to the question here, is the Android Library Update step necessary and, if not, can it be removed from the startup and/or build process? A manual update seems like an appropriate option, especially if it improves build times and you already have a previous clean compile.
You can disable Android Development Toolkit from General -> Startup and Shutdown.
this may not exactly answer your question, but if you do have a lot of projects it will rebuilt all of it when you open eclipse. what i do myself is i "close" the projects that I'm not working on and I find it more tolerable
If you don't need to debug your native code, you could simply not add native support in the first place and just build it on the command line when needed. Then your eclipse project would simply act as a Java only project and build quickly.
I had this problem with 50 ish projects in my workspace. Not all of them are open at once. Still the 'Android Library Update' would show up every time I needed to update a small thing on every project and really slow me down.
I tried following but the last one worked like a charm for me.
Obviously, opening only related projects helps too.
Removing Build Automatically gets rid of this problem but makes twice more problems. You end up wasting more time manually building the projects. Didn't work for me at all.
Selectively building only the projects that changed helps too.
But the main thing that completely fixed this problem for me was following
Go to Window->Preference->Android->Build and make sure the third check box Skip packaging and dexing until export or launch. is marked on.
