I cloned a project from GitHub using Android studio and I tried to run it, but I get the following error when trying to run it:
This should be able to run as I was the one that made it and uploaded it to GitHub. I just couldn't figure out how to use GitHub so I decided to clone the entire project back on my computer and it wouldn't run. It's actually also one of the templates from Android studio.
I tried looking online and I saw posts mentioning options along the lines of "syncing project with gradle", but I can't find that option anywhere in Android studio.
Not sure if this adds more information but in my original project that works and runs, it is able to show the design of the app but in the cloned version it doesn't show any of that, just code.
Resync Gradle is in File->Sync project with Gradle Files.
Has the project been pulled? Have you checked the project for errors? Do a build and see what errors there are.
My guess is there is stuff in the project (i.e. libraries) that do not exist anymore in the version of Android Studio you are using. Maybe the project was created with an old version of android studio. Also, check the Gradle app file and see if there are any problems.
After updating Android Studio and Gradle to 3.5,
I now get this error:
NDK Resolution Outcome: Project settings: Gradle model version=5.4.1, NDK version is UNKNOWN
I changed the Gradle version in build-gradle back to 3.4.2 but it didn't help.
I had similar problem and solved it by opening project using Import project (Gradle, Eclipse, etc.) instead of Open existing Android Studio project.
You can download NDK from File>Project Structur>Choosing SDK location from left panel and pressing Download from NDK location part.
I was having the same issue after upgrading my android studio. You just need to open local.properties & change ndk.dir path to your NDK path.
Code:
ndk.dir=D\:\\Android\\SDK\\ndk-bundle
sdk.dir=D\:\\Android\\SDK
I don't use NDK in my project, but I had the same problem. The problem disappeared after I updated the SDK version to the newest
compileSdkVersion 29
I had a previous answer (since deleted by moderators) where I detailed that there are workarounds (as listed here) that work for some but that there is an underlying bug in gradle because the workarounds don't work for everyone (specifically: none of them work for me)
The related google issue is here: https://issuetracker.google.com/issues/140403764
Update: As of today (20190920) they indicate that they have fixed the underlying issue, so I would expect a future release of gradle after today (20190920) will contain the fix.
Update2: Today (20190926) I received a response from a googler that the problematic code was in Android Studio and it is contained on the 3.6-release branch but is not available on any publicly available build at the moment (Android Studio 3.6 Canary 12 was released just before this fix was made). That lets you know which component to update and which versions to pay attention to, anyway. Looks like Android Studio 3.6 Canary 13 and later should have it https://issuetracker.google.com/issues/140403764#comment13
Until then you can try the workarounds but when there's a vendor bug and workarounds don't work you just have to wait for a vendor patch.
You need to install NDK using the SDK manager
I first got this issue after upgrading from Android Studio 3.5.0 to 3.5.1 today.
I simply did a rebuild from the top menu Build --> Rebuild Project.
This might not work for everyone depending on what caused the issue but it worked for mine. Give it a shot.
(Also, I do not use the NDK and never have downloaded it before. Still don't have it downloaded)
If you are not using NDK, ignore the error.
I have installed NDK to see if this makes any difference. There is no difference (except for an unused NDK folder of more than 2 GB :). So I removed it (i.e. delete the ndk folder and remove NDK environnent variable you have set previously).
After my recent Android Studio upgrade I had the same error message. I tried the other answers here and none worked. But #Zahra's answer pointed me to something that did work:
Go to File->Project Structure...
Under "Android NDK Location", click the dropdown and select the "DEFAULT NDK Recommended" option.
There was a slightly different path in there before I selected the default. Somewhere upgrading using the SDK manager, the path seems to have changed.
And now in the local.properties file sdk.dir is set to the same directory as the "DEFAULT NDK Recommended" option.
i fix it by going to file > Invalidate Caches\Restart
the IDE will restart and the problem will fix
I had same problem. My environment is:
Android Studio 3.5.1
Gradle 4.4
Android-Gradle-Plugin 3.1.2
CMake 3.10 and 3.6
I uninstalled CMake 3.10 by SDKManager. (installed CMake is 3.6 only)
Gradle sync and build succeeded.
(1)
android-gradle-plugin 3.1.2 used CMake 3.10.
In android-gradle-plugin 3.1.2 (or 3.1.+), feature of support for CMake 3.7 and higher is a preview feature.
(from output message of gradle assembleDebug or gradle sync.)
(2)
https://developer.android.com/studio/projects/add-native-code.html#use_a_custom_cmake_version
The SDK Manager includes the 3.6.0 forked version of CMake and version 3.10.2. Projects that don't set a specific CMake version in build.gradle are built with CMake 3.6.0.
Perhaps this behavior is android-gradle-plugin 3.3 or higher.
(it is from android-studio 3.3 that can be downloaded CMake 3.10)
android-gradle-plugin 3.1.2 used latest version from installed CMake.
I had the same issue on a mac as well.
Suggestion: Force the .gradle folder to rebuild itself..
This still shows the 'NDK Version is UNKNOWN' in the Event Log yet it builds successfully and doesn't give me any issues. (I don't have NDK downloaded)
Open your /Users/macuser/ folder
Press CMD + SHIFT + . (dot/period) to view hidden folders
DELETE .gradle folder
Restart Android Studio
This will cause Android Studio to rebuild and re-download your .gradle folder fixing your conflicting files in the process.
The problem is solved when I updated the Android Gradle Plugin Version from 3.1.4 to 3.4.0 and the Gradle Version from 4.4 to 5.1.1 at the same time. Of course, I downloaded the newest NDK(Side by Side) with SDK manager.
In my case, Android Studio was installed on a new mac. Just needed to download Android 9 (my target/compile SDK was 28) and build tools. The problem was solved after this.
In my case i fix it by upgrade to SdkVersion 29 and migrate to AndroidX.
After upgrading I've got the very same problem in one of my projects.
I solved it just deleting the line ndk.dir=D:\Android\SDK\ndk-bundle from the local.properties file.
I had the same error after adding a couple of libraries in the app-level build.gradle file.
The solution was just to clean the project.
In the menu bar choose: Build >> Clean Project
After that, the error was gone for me. I didn't do anything else.
I got this error (and several others) after importing a project from version control via Bitbucket hyperlink.
Once imported, close the project and re-import it using File > New > Import Project. After that everything built correctly.
(The NDK path was already specified properly, and only importing as new worked)
Meta:
Android Studio 3.5
Build #AI-191.8026.42.35.5791312, built on August 8, 2019
JRE: 1.8.0_202-release-1483-b49-5587405 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
macOS 10.13.6
Gradle 3.4.0
Problem solved for me after checking Suggestions in Project structure and updated the two suggested updates. Sorry I can't remember the module names as they disappeared as soon as I pressed update for each of them and graddle sync. started automatically and after this problem disappeared
downgrading ndk version from 20 to r17c and cmake version from 3.10 to 3.6.411459 solved the problem for me
I had the same problem after updating Android Studio.
My problem is solved by after updating Android SDK Build-Tools.
[Tools->SDK Manager->SDK Tools->Android SDK Build-Tools].
Then try to Clean the project
[Build->Clean Project].
Finally restart the Android Studio IDE......
I just closed project, closed android studio, restarted my PC, tracked my project and deleted the .Idea folder in "B:/PROJECTNAME/.idea" and voila.
Problem solved. It resyncs. N/B: my gradle is androidx. goodluck to someone.
Change the claaspath to 'com.android.tools.build:gradle:3.5.2' in build.gradle script
Ok. I recently downloaded the latest version of Android studio and got similar error. So eventually I created a new project.
Selected Kotlin Language then Jelly Bean (talking 'bout the options to pick from).
Then the whole synching began but the 1st sync failed and eventually it auto-synced again and everything began to work.
Did modify the default codes (text) since I'm a beginner but got no error messages.
The preview was OK and I continued my learning.
Sorry I couldn't explain it better. I'm just a beginner.
Oh! You need to be connected to the Internet for it to work.
If this problem occurred after an Android Studio upgrade and you initiated a plugin update from right bottom notification: Open File > Project structure, then change the Android Gradle version to your Android Studio version and downgrade the Gradle version to the previous one.
In my case, I downgraded the Android Gradle plugin from 3.5.3 to 3.2.1 and the Gradle version from 5.4.1 to 4.6.
I modified the gradle version of the gradle-wrapper.properties file from 4.1 to 4.6.
I had this problem and none of the solutions worked for me. Problem is, this error or warning might appear for very broad reasons. You can follow these steps to find out what is wrong:
NDK is missing
When Gradle starts to compile native dependencies it creates ".cxx" folder in your "app" folder. inside that folder you can find "ndk_locator_record.json" file, which is very strange type of log file. It is basically all the paths Gradle checks to find NDK folder. If there is any error or mismatch on NDK version numbers you can see in this file.
NDK build fails
for some unknown reasons (maybe bug in Gradle) ndk build does not show actual error on event log window, instead it shows a failure, like Gradle sync failed: executing external native build for ndkBuild .... following by NDK Resolution Outcome: Project settings: Gradle model version=5.4.1, NDK version is UNKNOWN.
In this case go back to .cxx > ndkBuild > debug > x86(x64 or any other cpu arch)
Here in this folder you can find "json_generation_record.json" file, it is same type of log, usually last entry has the actual error. For example, for me was
../../sdk/native/jni/OpenCV.mk: No such file or directory
make: *** No rule to make target '../../sdk/native/jni/OpenCV.mk'. Stop.
From here you have a starting point to find out what is going wrong under hood.
If the NDK is not install, and the Android Project requires it then first install the NDK.
On windows OS add the NDK path to PATH environment variable. This will fix the version issue.
In my case the NDK path is
C:\Users\\AppData\Local\Android\Sdk\ndk\21.0.6113669
I faced this issue before and I fixed it by making sure to have the right permissions to the app directory.
I am using macOS, so I did:
chmod -R 777 your_android_project
and the issue was gone.
i have this problem too when I updated the Android Gradle Plugin Version from 3.1.2 to 3.5.1
Here is how to solve this issue :
Go to gradle.properties file in root folder of your project and add android.useDeprecatedNdk=true
I had minor problems in a project I was working on and use invalidate caches and clean to see if that would help. However that did something not just to that one project but to android studio in general. it does not recognize java, the appearance of even the home screen has changed. I can't start any new projects in java and none of the old work. Strangely, even after I uninstalled both studio and java and then reinstalled the same problem persists.
incompatibility between the Android Studio cache and your current project layout. If you suspect this is the problem, then select File> Cache / Restart> Validate and Restart from the Android Studio toolbar.
To set JDK location: you can see this video: https://www.youtube.com/watch?v=jA97GYqRODE
Try to clear Android Studio cache, assuming you're using v3.3, delete the cache folder located at:
C:\Users\your_username\.AndroidStudio3.3\system\caches
Can we use Android studio for AOSP(Android Open Source Project) development, is there a way to do it. I didnt find one. anybody got any idea on this please ?
You can use Android Studio as a IDE for AOSP, since it's just a modified version of InteliJ's IDE.
from AOSP root:
make idegen && development/tools/idegen/idegen.sh
Then just "Open Project" in Android Studio and select the android.ipr it generated.
To import AOSP source in Android Studio or Eclipse, follow the full instructions here :
https://android.googlesource.com/platform/development/+/master/tools/idegen/README
What Pedlar suggested above is one way of doing it. I ran into lot of Jar dependency issues when I tried it with IDEA community edition (Android Studio is a fork of IDEA IDE). The IDE keeps prompting you about duplicate jars etc. The generated project includes framework Java sources as well as App sources. I tried to build an App project which resulted in broken AOSP build. IMHO, IDEA is a great IDE for Java development. But didn't work well with AOSP.
What worked for me is using eclipse to browse/edit/debug framework sources, but build the code from a terminal window. To avoid AOSP build breaks, please create a shadow dir of AOSP (i.e. lndir of AOSP) and use shadow dir for eclipse project.
This is explained at Using eclipse to browse/edit AOSP link in step by step.
If you are working on AOSP, you might want to check Debugging Android framework services.
I implemented the current version of ActionBarSherlock to my Android Project.
Everything works fine and I don't get any errors.
But when I try to debug or export my project I don't get an .apk-file out of my project. Just a .jar-file with the name of my project.
I've read about some problems the SDK had with building projects that contain external libraries but this was at SDK version 14 and so I hope, this bug is fixed...
So there might be another cause for this problem.
Does anybody know a possible solution?
You cannot get *.jar file as the result of building Android project. This seems very strange to me. There must be something wrong with your project settings (if you changed them), or the project you build is of the wrong type (i.e. it is Java Application instead of Android Application).
You didn't mention which IDE do you use, but I assume you use Eclipse.
Make sure you have installed Android SDK and Eclipse ADT correctly (just in case).
Next thing to try is to create a new Android Application project from existing sources (there should be such option during the process of creation).
