I am working on a project that will have a 3D model viewer in one fragment. In order to do so, I decided to use sceneform.
I downloaded sceneform plugin into Adnroid studio, downloaded and extracted sdk from Github, and I also copied libsceneform_runtime_schemas library into my project. I've added to my sceneform buil.gradle file line
implementation files("../libs/libsceneform_runtime_schemas.jar")
but that results in an error:
Program type already present: com.google.ar.schemas.lull.AabbDef
It is worth noticing that this is the first file in the jar under this path - which probably means that there will be more collisions.
If I'd try not to implement this library, then I get an error:
error: package com.google.ar.schemas.sceneform does not exist
I am using ar:core:1.17.0, and minSdkVersion 24 in sceneform gradle.
I've cleaned and rebuilt the project, Invalidate Caches/Restart, and added multiDexEnabled- although I am not sure if I did it correctly.
By using gradlew sceneform:dependencies I didn't find mentioned file.
I don't know how I can move forward, any help is much appreciated. If I can provide additional information, please let me know.
Edit 1:
I've also tried to work with
implementation files("../libs/libsceneform_runtime_schemas.jar"){
exclude ...
}
But I couldn't make it work. I wonder if that could be my solution.
Also, why does it try to implement this class since it already exists? Shouldn't there be some sort of check for that?
I solved my problem by restoring my project from repo to the last moment before including sceneform, and I proceeded with all of the steps again; Gradle dependencies to the libsceneform_runtime_schemas, min java 8, min SDK version, copying scenformscr and sceneformux to my project again, and lastly - upgrading all classes to AndroidX.
After two days almost I couldn't remove the error, and I don't know what went wrong before, but this time it works like a charm.
TL;DR - I removed the sceneform from my project and imported it again.
UPDATE: Solved! (see fix at the bottom)
I'm trying to go through the Android Room tutorial but get stuck on step3. I keep getting an error when trying to update the gradle file as specified by the tutorial.
https://codelabs.developers.google.com/codelabs/android-room-with-a-view/index.html?index=..%2F..index#1
When trying to build, I get the following error:
Setting roomVersion to "2.1.0-alpha06" or just "2.1.0" generates the same type of error.
Is it only me or is there something wrong with this tutorial?
Anyone with an idea why the androidx.room:room-testing dependancy fails to build?
UPDATE:
I solved the issue by uninstalling Android Studio and re-installing it. I also needed to do a full cleanup and remove all "android studio" and "gradle" related files on my system. Maybe a bit overkill, but this is whats fixed it for me.
I would like to start a project in Android Studio, using Simple Facebook library.
I used to develop in Eclipse and things were fine, but now i had to face an issue while trying to make the libraries work with gradle.
I made a new project.
I made a module for official Facebook SDK inside "libraries" folder
I made a module for Simple Facebook library inside "libraries" folder
I got the following error:
Error:A problem occurred configuring project ':app'.
> Cannot evaluate module simplefacebook : Configuration with name 'default' not found.
I did my research and as everybody experienced this error message is not really informative, and i also tryed to solve this problem from stack overflow's other smiliar questions but just coudnt get it work.
Please help if you can.
And please mention in comment which gradle file you would like to see, because there are 5 of them.
Look in the docs from Facebook!
You don't need to place the hole project as library module anymore in android studio.
Facebook and many other API Providers provide ther Libs now over Maven and you only have to add the dependcy to the correct artifact in your apps build.gradle file.
Here example for Facebook SDK:
dependencies {
compile 'com.facebook.android:facebook-android-sdk:4.1.0'
}
Copied from here: https://developers.facebook.com/docs/android/getting-started
I havn't searched for the other lib, but you should find it your self on developers.facebook.com.
I have been following the instructions for integrating the facebook SDK into my apps. I have succeeded in getting all the given sample apps to compile and run except for "helloFacebookSample". For this I get a compilation error:
Project 'HelloFacebookSample' is missing required Java project 'facebook'
My understanding of projects/libraries/build paths etc is a little hazy, but I can not work out why this should fail where all the others succeeded.
Here's a screen grab of my properties window for HelloFacebookSample:
I can confirm that the directory:
c:\android stuff\facebook\facebook-android-sdk-3.0\facebook\bin
contains a file facebooksdk.jar
Any ideas?
EDIT: Thrashing around some more, I just clicked on the "projects" tab that you see in the screen grab above, and saw that it says "facebook (missing)". I'm a bit confused because I thought that projects may need to rely on libraries rather than other projects... but still I have no idea how to resolve the problem. I don't seem to have a project called simply "facebook"...
Edit: thrashing around some more, I just experimentally deleted the "facebook (missing)" from the java build path and then did an "add" of "FacebookSDK"... I thought this was cluttching at straws, but to my surprise it worked!!! HelloFacebookSample compiled and ran!!! - I have no idea what's going on though and would still like an explanation.
The previous version of the Android Facebook SDK referred to the project as 'facebook'. It looks like this sample was not updated to delete the old reference, and add the new one to 'FacebookSDK'. You took the corrective steps to resolve this yourself already by modifying the Java Build Path of the project.
The problem will easily be removed by simply going to the properties of your project and right clicking it, then go to project tab, select the project which prompts missing and remove it.
Now click on project->build project->clean
Now run your project and it will surely do fine
Encounter this problem when trying to Build Project getting such output in console:
[2010-07-19 23:29:23 - myProject]
trouble processing "javax/net/SocketFactory.class":
[2010-07-19 23:29:23 - myProject]
Attempt to include a core VM class in something other than a core library.
It is likely that you have attempted to include the core library from a desktop
virtual machine into an application, which will most assuredly not work. If
you really intend to build a core library -- which is only appropriate as
part of creating a full virtual machine binary, as opposed to compiling an
application -- then use the "--core-library" option to suppress this error
message. If you go ahead and use "--core-library" but are in fact building
an application, then please be aware that your build will still fail at some
point; you will simply be denied the pleasure of reading this helpful error
message.
[2010-07-19 23:29:23 - myProject] 1 error; aborting
[2010-07-19 23:29:23 - myProject] Conversion to Dalvik format failed with error 1
I was looking for my project to use the package javax, not found, clean all also does not help. what I am doing wrong?
Update
Sorry guys, but I could not find good fix for that, I want to emphasize the fact, that i dont use SocketFactory class in my project at all! source code was not changed before this problem, and that's why i think that problem in eclipse or adt or something else, BUT if i use ant(generated by sdk) to build this project there is no problem!!!
I solve this problem by removing Eclipse, Android SDK, Eclipse workspace, and just reinstall them, after this all works fine for now.
Hope this will help someone.
I had the same problem..
This worked for me
project-->properties->java build path->libraries-> remove all including android jars
now go the project browser, right click on the project you are working on,
then android tools---> fix project properties...
do a clean and then build...
I solved the problem (at least for me).
Here's what I did:
Go to Project » Properties » Java Build Path » Libraries
Remove all except the "Android X.Y" click OK.
Go to Project » Clean » Clean projects selected below » select your project and click OK.
That did the trick for me.
Hope it works for you as well
Update: well actually I might have to retract my opinion.. the actions removed the error messages but now I am missing certain classes and methods... arggghhhh
I just restarted Eclipse, and the error didn't appear anymore!
I had the same problem,and solved it as follows:
First clean all jars; (This problem must because your some jars)
Delete the project;
Reimport project;
Make sure your sdk is right, and project select one sdk version;
(This is my issue to solve the problem) Right click your project, and select "build-path", next select "add Librarys", and add your private jars;
clean-build, the problem has fixed;
I just had the same problem and I tried all of the solutions listed here with no success (I was starting to get annoyed). Then I removed the project from the workspace and then imported it again, and there were no problems!
This happened to me this way,
I have a quite an old project which I had to start working again today. I use 'Universal Image Downloader' library for basically every project where I have to deal with lots of images. So in this old project I had the source files of 'Universal Image Downloader' included to it's 'src' path. Back then I was a newbie and slowly I started developing my own library which could handle every day simple Android development tasks very easily. Obviously I included the 'Universal Image Downloader' to this.
After dusting off the old project today the first thing I did was to reference my library to speed up the development process but as I was trying to debug I ran into the "Conversion to Dalvik format failed with error 1" over and over again. First I thought it was the support library but even after clearing all libraries and adding only mine and doing a quick 'Fix project properties' I still got it. After trying various solutions I noticed this in the console "java.lang.IllegalArgumentException: already added: Lcom/nostra13/universalimageloader/cache/disc/BaseDiscCache;"
It was as simple as that... I'm trying to compile a class which has already been compiled.
Solution : I just simply removed all the class files I got from 'Universal Image Downloader' library from the 'src' directory. Since my library references "Universal Image Downloader" library the old project started working just fine.
Hit same problem shown on your log when trying to run an example project which was imported into eclipse.
Additional Info: in eclipse's Problems View I see the following error:
"The project cannot be built until build path errors are resolved"
In my case the imported project find the libraries just right(by just right I mean I can see the external path to each of the android libs in this case 2 libs, android.jar and maps.jar). So no shuffling of libs in my case, but might be your problem.
I followed Spock's suggestion of cleaning the project which I had to clean multiple times until it somehow resolve its issues. After, issue was solved I had to specify an AVD for the project to run and soon after was up and running on the emulator. Also, note that my eclipse is set up to Build Automatically.
In my case I'm not missing any class files or anything after the clean as the build is properly generating them.
Regards!
I was getting the same error. My problem was that i had an android device hooked up to debug with. As soon as I unplugged it I was able to export.
The answer I found was checking the source and library build path in the project's properties. Most likely there will be a duplicate as in something being referenced in both the source and library tabs. So delete the extra in the source tab and then clean the project and you should be good to go.
Either:
javax.net.SocketLibrary is in your source code, or
javax.net.SocketLibrary is included in a JAR file in your project
Under certain conditions it gets its knickers in a twist and the best fix I've found is to remove referenced jars, clean, add them back in and then compile again.
I believe the error can be caused by including the same classes twice.
This error will also occur (and you won't be able to get rid of it by cleaning) when using classes that are not part of the Android environment.
To summarise the information in the link bimbim.in provided (well my understanding when I glanced over it)
The Android Davik VM tries to compile the jars but finds some stuff that it can't compile to .dex files
so
Just create a "lib" directory in the root of the project (where the src, bin res directories are) and add them to the build path. Project Properties... Java Build Path... Libraries.. Add JARs..
I could resolve this issue by creating a new project, looks like the some project settings were creating this issue and could not really find the root cause for that. But, dumping the existing source code onto the new project resovled this issue. If anyone has found the root cause for this problem pls do let me know.
I had the same problem and solved it as follows:
- Go to Project/Properties/Java Build Path/Libraries and remove all JARs except Android
- Do a project clean
- Add the JARs again as External JARs (first time I added them internally, so that might be the problem)
After that the error was gone.
I solved the problem by updating available packages in the Android SDK et AVD manager. No need to remove Eclipse.
Whenever the Project is having the ambitious data. This problem is caused. May be android can't able to find which one choose.
From what I understand, this same cryptic error could be caused from a wide variety of reasons. I've got "Conversion to Dalvik format failed with error 1" error too. In my case the problem was that for some reason Project -> Properties -> Java Compiler was not set to "Enable project specific settings" with proper Java 1.5 settings, but was left to defaults instead (1.6 in my case). Debug, build and test on devices/emulators worked fine, but export always failed with the above error message.
If unsure about the proper settings, create the same project on some alternative location and just copy all needed files from the old project into the new one. This fixed the issue for me.
The next problem with the same error message came from using proguard. Updating to the latest version by replacing the one that came with android sdk, fixed that.
Hope this helps
My problem was having a jar file in my src folder. Removing jars from the build path works, but only if you don't need the jar in question. For people who need the jar in question, make sure that your jar file is not in the project folder (maybe just src subtree, but I would keep it separate to test). Put it on your desktop or something and try the "Add external jar.." option. Be sure to remove the jar from the project filesystem before adding another external. Having both is what causes the problem.
I have done it as the instruction of the first answer and it works.(Linux)
I think the problem may caused by SDK or ADT updates.
I do have to clear all the lib in Java Building path and then use android tools to fix the project. After cleaning and rebuild, it works as before.
