I made a mistake and misnamed a TextView in the rumney forum class and now thr R.java file contains this variable. I have deleted all the rumney forum, rumney forum card and 2 pages but the error wont delete. I did a search and can only find this variable in the R.java file so im confussed? This error wont let me run my programme at all so please help :)
In android studio I usually get this done by clicking the "Sync project with gradle files" button and then on the top menu: Build > Clean Project and then Build > Rebuild Project.

When I was naming one of my activities in Android Studio, I accidentally clicked the "\" key and I've deleted that activity but now when I run the project it says I have an error in my .R java file..
I tried to delete the error which will fix my problem, but whenever I delete the line of code it just regenerates it when I run it again...
I've already tried; deleting the line, cleaning my project, and rebuilding my project. None have worked.
The line of code I need to delete is:
public static final int title_activity_song_one_hundred_nine\=0x7f0c0054;
How do I go about deleting this line of code for good? Thanks.
You need to clean your project by
Build > Clean Project / Rebuild Project. this should re-compiles your R file in android studio.
If still not work, you must have errors in your resource files. Check your xml files such as layout, string, etc.
Try this...
Close your app in an Android Studio/Eclipse.Go to your workspace where you have the project.Open that R.jave file in notepad and remove the "/" symbol then save it.
Now open it in Android Studio/Eclipse IDE. Your error may fix.
I have a problem with intellij idea. Previously I used Visual Studio and now I decided to try to write code with Intellij. But it seems to me incomprehensible. I created new project (Android gradle application) and I cannot find where the source code is:
There a a bit of some files and no source code files. And when i opened folder containing my project i found source code subdirectory.
All source code files are in "Third" folder. But this folder is not shown in "project" panel. How can I fix it?
Have you tried clicking on "drop arrow" next to the text "Project"? It is on the third row from the top.
It gives you the options of selecting between "project", "Android", and "Package".
Please select "Android" and see it you can find the files.
p.s. just noticed this even though it was posted a while back. Pls kindly tick correct answer if it works out for you. Thx.
My R.java gives an error
public static final int 1405308882_more = 0x7f020000
Don't know or understand why its giving this error, i regenerate the R.java file and it still gives me the following above. and when i hover my mouse over it, it says
underscore have to be located within digits
I tried editing it but when it compiles it still regenerate the same name variable.
Please before anyone starts rating this question as usless take your time to understand it
I don't have error in any of my java files either in the src folder or layout folder every thing else is fine its just the R.java that generates that constant so please understand before you jump to conclusions. Thank you.
There might be some thing error in your res folder once check each and every file and clean your project once and refresh it again..
Sounds like the R.java file has not updated, try some of these general pointers to begin with:
Do not manually edit any of the files in the gen folder, as these are automatically built for you.
If you find it is out of sync then try refreshing the project.
If that did not work try a clean (project -> clean)
If that did not work delete the gen folder, from within Eclipse, (do not panic) it will then be rebuilt by Eclipse - however if there is a coding error of some sort it may not do this straight away.
Hope this helps..
It wasn't the XML file that was the issue. It was an image in the resource folder with a name that didn't follow the standard naming rules and thus made the R.java to generate that error.
The reason it regenerates same is because it regenerates from your code you should check the .xml files of this project the problem is probably at 1 of them try clearing xmls you have created then regenerate it.
I was doing some work on my app when I accidentally deleted the file R.java in the gen folder. Is there any way to get it back? I need it because it is giving ever activity errors. I tried copying my data into another application and that didn't work. I also checked my recycle bin and there was no file and cleaned. Please help?
Several ways to get out:
Simply modify(add a white space or so) in one of your resource files and save it, if the eclipse is enabled 'build automatically', the R.java will be re-generated again.
Go to project - clean project, clean your project and it will be re-generated when you run the project again
It is automatically generated file
Just clean and rebuild you project If there is no error{there must not any xml error which neither shown error nor let R.java build} then it will create your R.java file
again
Every Successful build just re-create new R.java file
R.java is auto generated when you delete it, make sure the xml file has no error . If this is also not solving your problem the start doing your project from scratch no copy paste.
My android.support.v4.jar is in my libs folder and in my android private libraries also.
But I got a problem appearing over top of my my xml layout saying- "The following classes could not be found: - android.support.v4.view.Viewpager."
I'm not sure whats wrong please help! I've searched around many forums and nothing seems to be working. The same problem occured when I tried integrating admod into my application it said, on the xml layout, The following classes could not be found: - android.support.v4.ads.AdRequest. I have a hunch it has to do with my jar being in the wrong spot..
hey i've fixed this by converting the ViewPager
from "android.support.v4.view.Viewpager" to "androidx.viewpager.widget.ViewPager".
to do that you just have to open up the .xml file > design and then right click on that ViewPager > Convert view as shown the next picture
then you just type viewPager and the search bar will auto complete that.. thats all of it.
Hope this fix the issue like it did to me.
You have to reference your project with this library.
Make sure you have downloaded the Android Support Library using the SDK Manager.
Create a libs/ directory in the root of your application project.
Copy the JAR file from your Android SDK installation directory (e.g., /extras/android/support/v4/android-support-v4.jar) into your application's project libs/ directory.
Right click the JAR file and select Build Path > Add to Build Path.
