Android : Run CMake manually via gradle

I am working on an android project which use C++ code.
I have added required CMake settings in build.gradle:
externalNativeBuild {
cmake {
path file('jni/CMakeLists.txt')
version '3.18.1'
}
}
But the problem is there are a lot of C++ files. Using gradle for build makes Android Studio index those files and it makes IDE very slow.
Is there a way to invoke CMake task manually outside IDE so that IDE don't index them? Actually what I want is to use a gradle task to build native code via CMake.

I'm working on Flutter app. I can run app in the android device successfully but try to make build (.apk) file and got below issues.

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.
Building plugin firebase_messaging...
The plugin firebase_messaging could not be built due to the issue above.

My app is compatible with AndroidX and also tried with many solution but can't able to fix my issue.
I checked

- A failure occurred while executing com.android.build.gradle.internal.tasks
- flutter Error "Android dependency 'androidx.core:core' has different version" using flutter_local_notifications and location packages

~PS : Let me know if you want more details from my end.

The issue is some library is not compatible or not using androidx while others are. Thanks to google for transferring all support lib to androidx now many libraries having conflicts like this and I mostly go to debug around which lib has an issue like commenting and uncommenting the lib from pubspec.
Assuming the flutter_twitter plugin was the issue.
As we can check that, that twitter plugin not using AndroidX link so we need to change it our self.
(all these changes needs to be changed in twitter plugin, not flutter project)
I think you can change the gradle.properties to use androidx and also compile version to 28
gradle.properties:
android.useAndroidX=true
android.enableJetifier=true
add this two lines, change gradle classpath
classpath 'com.android.tools.build:gradle:3.5.3'
and compileSdkVersion 28 in flutter_twitter.
I am able to generate release build using that plugin.
Ohh yah you can find your cached version of plugin at /Users/parth.dave/.pub-cache/hosted/pub.dartlang.org/flutter_twitter_login-1.1.0/ something like this where you can update it. or either open android folder in androidstudio and studio will show you two projects app and twitter where you can update this things.
also sometimes it's better to open android project in android studio and update all things from which you might get errors before running flutter projects.

Problem is with Execution failed for task ':flutter_twitter:verifyReleaseResources'.
i found link for this issue
flutter_twitter_login/issue #12
Add this dependency in your pubspec.yaml file and let me know this working or not?
flutter_twitter_login:
git: git://github.com/eudangeld/flutter_twitter_login.git

Goto the android studio external libraries in the left side
--> select the library that cause this issue
--> then goto the android -> build.gradle and update the compileSdkVersion to 28

You need to update the compileSdkVersion of the flutter_twitter module to 28 :
1/ In your flutter project, locate your "android" folder and open it as an android project in Android Studio.
2/ Expand "Gradle Scripts" and wait for it to load.
3/ Locate "build.gradle (Module: flutter_twitter)"
4/ Modify the compileSdkVersion from 27->28.
5/ Save the changes.
My build worked after that.
The answer was here : https://github.com/flutter/flutter/issues/32595

thank you, it worked for me for device_id: ^0.1.3
plugin conflit with cloud_firestore: ^0.13.4+2
In your flutter project, locate your android folder and open it as an android project in Android Studio.
Expand Gradle Scripts and wait for it to load.
Locate build.gradle (Module: device_id)
Modify the compileSdkVersion from 27 -> 28.
Save the changes.

I faced a similar issue and here is how I fixed it by following this link.
In Android Studio (with your project open) right-click the android folder, and click "Flutter"->"Open Android Module in Android Studio". Select "Open in New Window"
In the new window, Wait for Gradle to finish the sync
Expand "Gradle Scripts"
Locate "build.gradle (Module: flutter_twitter)" or which so ever package is throwing the error
Modify the compileSdkVersion from 28->29 (or whatever is defined in your android/app/build.gradle file).
Save the changes and run flutter clean
Build the signed apk.

seems like your firebase_messaging library version does not support AndroidX support. Make sure you have updated version of this library.
dependencies:
firebase_messaging: ^6.0.9

I had the same problem before and it took almost a half day to find a solution.
My project compileSdkVersion was already 28 but in my case app-usage package compileSdkVersion was under 28 and i had to change it manually in
/home/"user"/.pub-cache/hosted/pub.dartlang.org/"package with problem"/android/build.gradle.
and it solved the problem.

Android Gradle Build: duplicate entry: META-INF/app_release.kotlin_module

I'm trying to build a release app via Android Studio > Generate Signed Bundle or APK > Android App Bundle > Release
However gradle fails with
: > Task :core:transformClassesWithMergeClassesForRelease FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':core:transformClassesWithMergeClassesForRelease'.
> 1 exception was raised by workers:
java.util.zip.ZipException: duplicate entry: META-INF/app_release.kotlin_module
In my build.gradle I've tried adding:
packagingOptions {
exclude 'META-INF/app_release.kotlin_module'
}
But it isn't making any difference whatsoever.
How do I fix this?
For extra context, it's a multi module project.
I have a core module, and an installed module which is declared in the core build.gradle with dynamicFeatures = [":installed"]
Thanks

Please make sure all your dependencies are api or implementation,
I have the flowing dependency grap.
meemo_sdk:
api project(":gvoice")
app project:
implementation project(":gvoice")
implementation project("meemo_sdk")
It complains "META-INF/gvoice_debug.kotlin_module" collision.
After change api to implementation, it works!

So I figured it out.
I pressed shift twice in Android studio (to open up the search everywhere dialog) and searched for app_release.kotlin_module
I saw two files, that were under two of my dependencies (which funnily enough were libraries that I had created!)
I opened up these library projects, and in the build.gradle file I had to add:
ext {
PUBLISH_GROUP_ID = 'com.companyname'
PUBLISH_ARTIFACT_ID = 'packagename'
}
android {
...
compileOptions {
kotlinOptions.freeCompilerArgs += ['-module-name', "$PUBLISH_GROUP_ID.$PUBLISH_ARTIFACT_ID"]
}
}
Rebuilt the library projects with new versions, used these new versions in my other project, and it started compiling :)

Build -> Clean Project Worked for me

I found the same issue comes randomly by using Android Studio 4.2.1 and Java8, I sorted out successfully by deleting .gradle file in the project (not the main one) every time I get the error.
Java version: JDK8221
Kotlin: 1.5.0
AndroidStudio: 4.2.1
Not the best solution but is a good workaround for now.

can you help me with this error in android studio?

I'm trying to run a project that is using a C++ module i try everything and nothing works it still get this error.
Error:Execution failed for task ':pulseandroid:compileDebugNdk'.
Error: Your project contains C++ files but it is not using a supported native build system.
Consider using CMake or ndk-build integration with the stable Android Gradle plugin:
https://developer.android.com/studio/projects/add-native-code.html
or use the experimental plugin:
https://developer.android.com/studio/build/experimental-plugin.html.

1 - Make sure NDK is install
2 - Put this part in build.gradle(Module:app) above buildTypes{}
sourceSets {
main {
jni.srcDirs = []
}
}
buildTypes{}

Android Studio: Add .cpp file tree without building

Is it possible to add a tree of .h/.cpp files to the Android Studio editor for reference - so that they can be edited but not actually built/compiled by Android Studio?
I have JNI/NDK files which I want to build manually from the command line but I don't want Gradle/Android Studio to build these files.
There is a Gradle 'exclude' command/function which may be what I need but I cannot get it to work.
sourceSets {
main {
exclude 'jni'
//exclude ("jni/**")
//jni.srcDirs = []
}
}
I get the following error:
Error:(10, 0) Gradle DSL method not found: 'exclude()'

I didn't manage to figure this out with a vanilla Android Studio set-up but by using the Gradle Experimental Plugin I have ended up with the desired outcome. Once I got the 0.7.0 experimental plugin working (and my build.gradle configured for the new 'model' scoping), I was able to remove the sourceSets statement, successfull sync, edit within Android Studio and build from the command line via ndk-build.
