In Android Studio, I am getting the following error when trying to run my app on an Android device:
The specified Gradle distribution 'https://services.gradle.org/distributions/gradle-7.2-bin.zip' does not exist.
All my Android Studio projects are affected by this and restoring them to older commits does not change anything.
The problems all started by following the advice given here: Could not install Gradle distribution from 'https://services.gradle.org/distributions/gradle-2.1-all.zip'
I deleted everything in my /.gradle/wrapper/dists/ folder. Now, I get the above error and I do not see how to solve it.
Here is how to reproduce it with Android Studio 2021.1.1 on Windows (but be warned: this might corrupt your projects, too):
Delete everything in /.gradle/wrapper/dists/
Create a new project "Test" in Android Studio (this might take a while, since gradle-7.2-bin.zip will be downloaded in the dists folder)
The project builds and runs without errors
Close Android Studio
Delete everything in /.gradle/wrapper/dists/ again
Open project "Test" in Android Studio
Try to run
Now you should get the above mentioned error.
At this point, /.gradle/wrapper/dists/ is still empty. Now you can do the following:
run gradlew tasks in Terminal in the Project Folder of "Test" (this will take a while, since gradle-7.2-bin.zip will be downloaded in the dists folder again)
run gradlew build (everything should build without errors)
But clicking on "Run" still yields the same error.
I am getting the impression that this is an AndroidStudio / IntelliJ bug.
Can anyone help me with this?
Running Android Studio as Administrator solved the problem for me
It turned out my Android Studio installation was heavily corrupted. Simply, uninstalling it and installing it again also did not help.
I basically had to do everything that was suggested here: How to completely uninstall Android Studio from windows(v10)? and delete everything related to Android Studio. I installed it again and now everything is fine again.
I do not know what the problem was. Maybe the .m2 folder, maybe the Jetbrains folder.
My advice to everyone facing the same issue:
First try around deleting caching folders. If nothing helps, go for the brute force approach and follow the answers (not only the accepted answer) of the above mentioned StackOverflow question.
I need to build openh264 library for android. I downloaded from official webpage(https://github.com/cisco/openh264).
I'm following the same steps. It's working with android ndk15, not working with latest ndk19. Because they have removed the stlport from new ndk19. using ndk15 build library is not working for latest android OS. so I need to build with ndk19.
while building with ndk19, its giving the error like,
Android NDK: APP_STL stlport_shared is no longer supported. Please
switch to either c++_static or c++_shared. See
https://developer.android.com/ndk/guides/cpp-support.html for more
information. . Stop. build/platform-android.mk:51: *** Compiler
not found, bad NDKROOT or ARCH?. Stop.
can anyone please help me out of this issue?
Android Studio displays in all java files in red : “cannot resolve symbol R” but the project compiles and runs.
I have tried every solution here:
Android Studio "cannot resolve symbol" but project compiles and works, but with no luck.
I tried to :
invalidate caches and restart android studio
delete .gradle and .idea folders
clean and rebuild the project
install a new version of android studio
mess up with gradle file then undo changes and sync project
One thing that I want to try, but I don't know how to achieve, is to reopen the project from scratch as I was opening it for the first time, but I don't know how to do this.
I also tried answers from here:
Android Studio says "cannot resolve symbol" but project compiles,
but again with no luck.
Android studio version = 3.2.1
dependency versions in gradle project file:
classpath 'com.android.tools.build:gradle:3.4.0-alpha01'
classpath 'com.google.gms:google-services:4.0.0'
For some reason that i do not understand ,
this combination of build versions made the issue :
grade version = 4.10.1
classpath 'com.android.tools.build:gradle:3.4.0-alpha01'
when i switched to these build versions :
grade version = 4.6
classpath 'com.android.tools.build:gradle:3.2.1'
The issue was solved !
File -> Close project
Open an existing Android Studio Project
Open you project
Hope it will work.
sometimes, R file is not generated because of package name on android manifest is not match with package module that you have.
Is any wrong syntax or spelling in your xml?
Check your layout or any xml file.
Android Studio seems to have a caching issue with R.java occasionally. I rarely have a problem with this, but when I do, I actually open R.java (double press shift and type "R.java") or navigate to R.java under "app/build/generated/source" directory, opening the file and checking if the relevant XML id has been created. If it has, it forces Android Studio to now recognise the id's that are not being resolved. It's quick to try, and doesn't require clean and rebuild.
From your programs menu, open android studio. instead of opening your project from the recent files, select to open a project from your computer and then locate the path to your project. When all else fails, sometimes this works.
Also, try commenting out the support libraries from your gradle implementation, sync your project, and after sync fails comment them back in and sync again. (not sure if that's what you tried already when you said you messed with the gradle file)
In my case,
I am using
- Android Studio version 3.3.1 at home
- Android Studio version 3.2.1 at office
When i pulled projects to my office computer that are firstly created at my home computer ,
Android Studio can not resolved R file but runs application with no error. Because projects gradle and Android Studio version are incompatible.
Only thing that you sholud do, change the gradle version in project level gradle file
classpath 'com.android.tools.build:gradle:3.3.1'
to
classpath 'com.android.tools.build:gradle:3.2.1'
I was facing same issue,
first thought the issue might because of some xml file or naming of drawable resources incorrectly. After analysing, this case wasn't applicable to me.
So
Updating Android studio from older version 3.2 to newer version 3.3.2 along with new build tool version from SDK manager resolved this issue
for me.
I've tried invalidate cache and Restart AS with clean rebuild all the options but didn't work for me.
It says cannot resolve symbol, but it can run.
In my case, I just reload the needed *.jar files to the libs folder.
File >> invalidate caches/restart
Rebuild Project
Sync
Run
Works for me!
It looks like the library did not load my "imports" properly the first time.
That's why the import methods cannot be seen in my main_activity.xml.
This happened to me when I was going back and forth between different SDK versions.
Apparently SDK manager copied all the source files but it didn't finish cleanly. As a result I could compile and run my project just fine but IDE didn't recognize the SDK and reported all java symbols unresolved.
None of the above and other solutions in SO didn't work for me, but just uninstalling/reinstalling the specific SDK version did a job.
If you renamed your package (inside java folder), make sure you change your Manifest package name to the same
The only thing that worked for me was,
replacing,
import package_name.R
with
import package_name.*
simply go to project settings : settings.gradel and change the rootProject.name to your current name
rootProject.name = "write the project name here"
I updated to AS 1.2 and I just tried importing/opening one my previous projects that worked on the previous version of AS. However, when I try building the project, I get an error saying
Error:Android Source Generator: [app] AndroidManifest.xml file not found
but this doesnt make sense since my manifest is src/main folder. How can I fix this and avoid this problem for all of my other projects?
This also bothered me recently, and I'm guessing that Gradle wasn't building it right.
In my circumstance, I just hit the Sync Project with Gradle Files button at left of AVD Manager button. If possible, you can goes with Gradle command lines as well.
then it popped out some errors said that I failed to find Build Tools revision 21.0.2(also this had been installed again and again, assuming I didn't set it right).
After installed some SDKs, clicked finish, studio will automatically rebuild your project.
There it works, can run the project now.
I have some issues in building ics-openvpn project. When I deploy the app on the device and try to import a .ovpn file, I get cannot find minivpn. I think this error is related to an error during the app building.
I've downloaded android NDK and set the path in Eclipse, downloaded cygwin and launched ./build-native.sh, but it returns me the error
./build-native.sh: line 1: ndk-build: command not found
I've tried to modify the path in the .sh with the path of ndk-build, but I get another error:
NON-CYGWIN COMPATIBLE MAKE PROGRAM.....
Anyone knows what steps I have to follow to properly build the project?
You should not try to build it with the cygwin. There is also a build-native.bat in the project which allows the project to be build with windows. Make sure that you have installed the ndk and ndk-build is in your PATH.
Run build-native.bat
make sure you must have NDK 8b and set the environment variable for the ndk file
