When I create a new project and run it I get an error message popup that says
Your project contains error(s), please fix them before running your application.
There is no problem with the code since it is a fresh project. I am new to Android and am working on Eclipse.
I do not know how I can solve this. Any help will be appreciated. I also tried to clean the project then recompile it but the error still recurs.
If you go to the windows menu, select show view, problems, it should take you to the problems view (it's usually at the bottom). That should have any errors listed in it.
It's also worth checking to make sure you don't have any open source files from other projects and that all files for the project you're working on are saved, as sometimes this can confuse eclipse.

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'm new with almost zero experience to Android Studio and i'm trying to change some settings of an APK.
First i decompiled the APK and then i imported it to Android Studio.
At this time, Android Studio shows me this:
My goal is to run the APK project on an emulator. This mean that i have to press the run button, which is disabled at this moment. After a research i made, i read that i have to sync the project with gradle files, but the sync button is not visible, as you can see on the screenshot above.
Can anybody give me a hint of what to do because i'm stuck here for a long time. Your help will be appreciated.
Thank you very much for your time!
You can't just Decompile an application and then using it inside another project as the new one.
The only thing you can do-use is, checking the java codes or xml codes of the written application to see how it works.
The point is, it won't work like that and you're doing it wrong. However, you'll be able to see not obfuscated java-xml codes inside the application. You can't just import it inside the Android Studio as a new Project like that.
I updated tools in my Eclipse first by going to Help->Check For Updates and installing everything i that it suggested. Then by going to Window->Android SDK Manager and updating multiple things including my SDK version.
After I have finished my update all my Android projects got a nice red box with an x inside it. I explored the projects and noticed that none of them had any errors inside the project just the project itself had the error icon. I searched online and i found that other people had similar problems. So i thought i found the solution. Alas after cleaning and building the project I got additional error icons next to multiple java files in my projects. Eclipse cannot locate the automatically generated R files when it tries to import them and all the imports are selected red.
I tried deleting the whole content of .android directory (starting with specific few files then the whole content) but that did not bring desired results.
So i have deleted the newly generated files and restored all the old ones.
When I clean and build the projects again all the errors disappear but only until I try to run the project again and then same error appears:
Your project contains error(s), please fix it before running it.
I have also found a related question. It claims that there must be a problem with my xml files. I did not modify any of my xml files since updating the tools so I dont know what could cause them to have errors.
Any ideas as to what is going on??
I've found that eclipse is now picking up errors that it didn't pick up before, because they updated lint, you may have to check all your files and see if there is an error because of this, if it doesn't work try removing Android from the build and reattach it, clean the project, build project, make sure the activities are using the right R files and check what lint says, its like a little square with a tick in it I think.
I had exactly the same problem, solved by removing any imports of R in my code and then cleaning the project
Strangest thing just happened. Even though I have done this 2 times before I have again deleted all my files in .android folder exited my Eclipse and opened it back up again. All the errors were gone and most of my projects work correctly. I have spend a lot of time on this problem and i dont know how it got resolved but Im glad its working again.
I just created a new Android project in Eclipse IDE, clicked on finish, and before even running project can see error symbol on project folder in eclipse IDE. If I expand folders, I don't see any red cross mark on any of files, can you please help me out. If I run as android project it says "Your project contains error(s), please fix them before using your application" . I am puzzled, it was a fresh project. Tried deleting and creating another project , restarting eclipse. Nothing works. Can you please help me out. Thank you for reading my post.
Lots of times Eclipse will fail to build Android projects properly. This might be eclipse.. it might be Eclipse's Android plugin. I'm not really sure. The way I get around it is by selecting from the menu Project > Clean... > Select the project giving you problems and hit ok. This will clear all built files and force it to rebuild, often fixing the problem.
There is a problem with the project itself, like the classpath or something. Go to Window > Show View > Problems (you may have to choose Other..., if so you will find it in the General section). In the Problems view it should give you more info. If you still can't figure it out post what the text from the Problem view.
i put this question in this forum because i am not sure whether this is an eclipse error or an Android error.
yesterday i created an Android application using Google Maps and GPS on Eclipse and it build and ran successfully however today i wanted to do some modification to the code so i started eclipse but it gave me an error.
SDK parse failed
if i try to run it. it says the apk cannot find. how can that be happened? the same application ran successfully on the same environment yesterday. i am using Ubuntu 10.04
Thanks !!
There is a problem with your project, as evidenced by the red x icon on your project title bar shown in the image above. Right-click your project, choose Properties and go through all your properties to make sure they are all still valid. It might be a reference to one of the jar files.
I get this problem all the time, hopefully my solution works for you.
To work around, goto your libraries inside the properties page.
Add any library and then rebuild your project.
Go back and remove the library later for clean up.
The project should still build.
