I am trying to build a ionic project in Android studio on Ubuntu 20.04 . I am using the command ionic capacitor build then android studio opens up as expected then it shows this error Gradle sync failed: Sync failed: reason unknown. I am unable find a solution for this particular gradle sync error. I have reinstalled Ubuntu and other things but still the problem persists.
In my case, a fresh install of Android Studio resulted in Android 31 being the only SDK available but the project was targeting Android 30. I went to Tools > SDK Manager and made sure the appropriate version of Android SDK was installed and available. After restarting, and allowing the gradle sync to complete I was able to build/run the app on a virtual device, etc.
Here is what I found
This is the screenshot thanks for helping.
Capacitor lets you manage your own Android project. Like any IDE-backed project, sometimes things get so out of sync that the only solution is to rebuild the project.
To do this, follow these steps:
Copy any source code you created (such as Java files in app/android/src, manifest files, or resource files) into a safe location outside of app/android.
Next, make sure you are running an updated version of the Capacitor CLI:
npm install #capacitor/cli#latest
Remove the android directory:
rm -rf android/
Re-create the Android app from Capacitor:
npx cap add android
Copy your saved source files back into the project.
Check the error log. You should find something like "Module: 'mobile' platform 'android-30' not found" or something similar. Click Tools > SDK Manager and download the appropriate Android SDK Platform package.
on top right you will see option to view log file upon clicking there you will redirect to file manager and open idea file there
example :
open idea file and scroll down you will see actual issue.
In my case android sdk 31 was not installed.
I installed android sdk 31 from File>Settings>Apprearance and behaviour>system settings>android sdk and install required android sdk and rebuild the project.
accord to my observation in most cases you get this error because you have not required sdk installed in your system.
Hello I've been looking to other similar questions about this problem but none has helped me so far, after I updated to android studio to the new version 3.6.2 I have this error when I try to run any project.
Run info:
Execution failed for task ':app:mergeDebugResources'.
Could not resolve all files for configuration ':app:_internal_aapt2_binary'.
Could not resolve com.android.tools.build:aapt2:3.6.2-6040484.

Content is not allowed in prolog.
Before the update the project was able to build now none of my projects build.
I tried invalidate cache and restart, I checked that I was not running in offline mode. still have the same failure. Any idea whay this could be and how I could fix it?
if you have problem with gradle
change your android stadio version to 3.6.2 or lower
file>project Strcture>
change to 3.6.2 and OK
I fixed the Error by going to my username and deleting .gradle, .AndroidStudio3.6 and .AndroidStudio3.5 folders. after I restarted android studio to download the folders again and resetting them. It worked.
After clean install of Android Studio I always get the error
Error:java.util.concurrent.ExecutionException:
java.lang.RuntimeException: No server to serve request. Check logs for
details.
and
Error:Execution failed for task ':Application:mergeDebugResources'.
Error: java.util.concurrent.ExecutionException: java.lang.RuntimeException: No server to serve request. Check logs for details.
Java is up to date and the path is set.
I am new to Android Studio, what should I try?
We ran into the same issue, and have been able to find the root cause: The error message means that Gradle cannot connect to some worker processes. In our case, the process was for 'aapt2'. Running 'ldd aapt2' indicated that some shared libraries were missing (mainly GLIBC). Since we're using Docker based on Alpine Linux, it comes with a reduced GLIBC (glibc-musl). The solution was to simply install glibc in the Docker container.
I suggest you run ldd build-tools/{version}/aapt2
to see which libraries are missing from the OS. You did not mention your OS, are you also using Docker and AlpineLinux ?
In my case, I did not need to re-download the sdk. I closed Android Studio and ran the following command in the Terminal:
sudo chmod 777 -R ~/Desktop/AndroidStudio
...where, ~/Desktop/AndroidStudio was the folder structure after Root which I needed to mention in order to provide permission to read all the SDK packages and perform required operation as and when necessary by the Android Studio, because my Sdk folder was inside "~/Desktop/AndroidStudio".
I am running Android Studio 3.0.1 on Ubuntu 16.04 LTS. This worked for me perfectly :-)
This error occurred because you might have accidentally remove the executable flag from aapt2 which is located in $ANDROID_HOME/build-tools/27.0.2.
Try this:
Re-download the sdk (recommended)
followed by-
sudo chmod 777 -R $ANDROID_HOME
Note:
$ANDROID_HOME is the location where I put android sdk
Hope this helps !!
Had to uninstall Android studio and delete the following
SDK folder in AppData folder
Delete .gradle folder
delete .AndroidStudio Projects folder
and did a fresh install which solved .
I had this problem on lubuntu-16 32bit (and also some other problems too). all of the problems were solved when I updated my system to lubuntu-16 64-bit.
Here how I fixed this Issue:
1.Deleted .gradle folder.
2.Closed android studio and run as administrator.
On Start android studio will rebuild the folder you deleted.
sudo chmod 777 -R $ANDROID_HOME
Note: $ANDROID_HOME is the location where you put android sdk
Hope this helps !!
If it is possible for you, please delete the build folder of project and test building android project with any other version of build-tools.
in my case, build-tools version: 26.0.2 had problem, I tested with 27.0.3 and it solved my problem unbelievably :)
I ran into the same problem, and it turned out I had messed up the file permissions inside the android-sdk folder (more specifically android-sdk/build-tools/{version}), and some binaries were missing execution permissions.
In my case, I simply gave x permissions to the relevant files in that directory, but if you're not sure, I suggest you uninstall the android sdk, completely remove its directory and then reinstall it again.
So after investigating the issue for long , I have a concrete solution .
Let`s look into it.
Go to Android Studio -> Help -> Show Log In Files
In the subsequent folder that opens, open idea.log
This would present you with a log file which contains logs of processes right from when the studio started. Now in this file, you have to search for the possible issue. For some the issue might be due to
java.io.IOException: Cannot run program "/home/mmt/Android-Sdk/android-sdk-linux_x86/emulator/emulator-check": error=13, Permission denied
For some others, it may be some other. The point is that this file contains lot of irrelevant logs and you have to identify the one that is causing this issue. For me , after discovering the above issue, I granted permission to that particular folder using the below commands
cd $ANDROID_HOME/sudo chmod -R 777 emulator/
After this, rebuild your project and tadaaa.. problem resolved.
for me it was a virus that corrupted my files from the "build tools" folder. so I uninstalled everything and made a new installation of android studio, SDK and build tools.
For me, this is the side effect of another issue that I haven't root caused yet. Every once in a while, I get aapt2 failures because some file /tmp/ld-linux-x86-64.so.2 is "busy", with the following error message.
AAPT err(Facade for 1745790725): cp: cannot create regular file '/tmp/ld-linux-x86-64.so.2': Text file busy
Slave 1745790725 failed to start java.lang.RuntimeException: AAPT slave failed to start. Please make sure the current build tools (located at ~/.../android-sdk-linux/build-tools/27.0.3/aapt2) are not corrupted.
When this happens I just rm that file and everything starts working again. I suspect this might be caused by me actually having two installs of adb (one through ubuntu via apt and one from Android studio) but I haven't had time to dive deeper.
I already had latest version of build-tool installed, so I just had to give permission to Android_home:
chmod 777 -R $ANDROID_HOME
and build again. This worked for me.
If you are on Windows 10 (sigh), close android studio and then right click on android studio icon and select 'Run as Administrator' from 'more' menu.
Build again.
You can run Android Studio as Admin.
I hope it will help you.
To Do So :
Right click
choose Run as Administrator
Best regards,
We have java 8 installed in ubuntu. And followed documentations said by google android studio. When we create new project gradle runs for some time and get failed. Following is a error
Gradle Refresh failed.
Error: no route to host.

Screenshot of gradle
Just Run Android Studio
[File]-->[Invalidate Caches/Restart] --> choose [Invalidate and Restart]
wait a moment...
Invalidate Caches/Restart not work for me. I found the global gradle.properties file there are some url that are not valid, I just delete them. (for Mac, the file should be in ~/.gradle/gradle.properties)
I have installed Android Studio and when I run it I get this message:
Android SDK was installed to C:\Users\Nathan\AppData\Local\Android\sdk
Refresh Sources:
Fetched Add-ons List successfully
Refresh Sources
Installing Archives:
Preparing to install archives
Download interrupted: URL not found.
Done. Nothing was installed.
The following SDK component was not installed: extra-google-m2repository
I have tried everything in similar posts I found here on stackoverflow, suck us downloading the plugin files of another version, and none worked for me.
Why is this happening?
I had the same problem. I started the sdk-manager manually and it installed lots of packages. After finishing and restart android-studio it started normally.
