Tabris.js Android in version 3.10.0 does not provide 16 kb page size libraries

[PatrickNass]

Problem description

Since November 1st 2025 the Google Play Store requires all new submitted apps and updates to existing apps, which target Android 15+, to support 16 KB page sizes on 64-bit devices.
https://developer.android.com/guide/practices/page-sizes?hl=en

The current problem is that "com.eclipsesource.tabris.android:tabris:3.10.0" includes two ".so" libraries which are not compiled for 16 KB page size, so it is no longer possible to provide updates to even existing apps.

Android Studio .aab analysis:

According to a ":app:dependencies" gradle run on the project "com.eclipsesource.tabris.android:tabris:3.10.0" depends on "androidx.camera:camera-core:1.1.0" which uses/provides "libimage_processing_util_jni.so" and a newer release is available in e.g. version 1.4.0, which provides a newer library version.
The other affected library is "libj2v8.so". This one is provided by "com.eclipsesource.j2v8:j2v8:6.2.1", which is also a dependency of "com.eclipsesource.tabris.android:tabris:3.10.0".

Due to this it is no longer possible to build apps which are being accepted by the Google Play Store.

To narrow the issue down all plugins in the project have been removed for a release build. So it is ensured that those affected libraries are not included by third-party dependencies.

Expected behavior

When executing an Android release build via tabris-cli the resulting .aab contains 16 KB page size libraries, so the app is being accepted by the Google Play Store.

Environment

• Tabris.js version: 3.10.0
• Tabris-Decorators version: 3.10.0
• Tabris-js-remote: 3.17.4
• Tabris-cli version: 3.10.0
• Device: all Android devices
• OS: Android 15+

Code snippet

Due to this being a general build/dependency problem and not a code issue, it should be reproducible with the "hello world" example. (not tested)

I don't think it's possible to substitute this in without access to Tabris' Android platform source code.

[mknauer]

Did you ever try to switch to the nightly builds?
I am currently living with

    "tabris": "3.11.0-dev.20250729",
    "tabris-decorators": "3.11.0-dev.20250526",

and still use a Tabris-CLI 3.10.0 for building.

[elshadsm]

This issue should be fixed with the latest Tabris Android Platform nightly build, which contains updated native dependencies for Android 16 KB page size support.

Could you please try the latest nightly platform from this URL?

After downloading this version of the Android platform, please also update the Tabris Android dependency to:

implementation 'com.eclipsesource.tabris.android:tabris:3.11.0'

This is needed to make sure the project imports the source code from the downloaded Tabris Android platform.

To import the source code from the local Tabris Android platform, create the TABRIS_ANDROID_PLATFORM environment variable on your operating system and point it to the downloaded platform root directory.

Then add the following Maven repository configuration to the allprojects.repositories block in your project-level Gradle file:

allprojects {
    repositories {
        ...
        maven {
            // provides tabris from directory repository
            url uri("${System.getenv('TABRIS_ANDROID_PLATFORM')}/templates/project/m2repository")
        }
    }
}

[elshadsm]

Additionally, if you want to build a Tabris.js app locally, create the TABRIS_ANDROID_PLATFORM environment variable on your operating system and point it to the downloaded platform root directory.

Then build the app locally, and the Tabris.js CLI will pick up the downloaded platform from the TABRIS_ANDROID_PLATFORM environment variable path value.

[PatrickNass]

I tried the proposed solution but could not follow the instructions exactly.
The app has been build locally. Gradle is not directly used in the project structure, it is used by the Tabris Android platform.
I tried two things to use the nightly build.

1. declaring/updating the versions in the package.json of the project

"dependencies": {
    "tabris": "3.11.0-dev.20260622",
    "tabris-decorators": "3.11.0-dev.20260303",
    "tabris-js-remote": "3.17.5"
  }

followed by a "npm install" + "npm ci". Afterwards the build has been triggered via Tabris CLI. According to the build log and this dependency analysis the nightly version has been used.

dependencyAnalysis.txt

I don't know if using the nightly of "tabris-decorators" is required as well but I changed it to the latest available version.
"tabris-js-remote" needed to be updated as well because otherwise this error occurs on a "npm install":

2. basically the same like in step one but I replaced the content of C:\Users\<user>\.tabris-cli\platforms\android\3.11.0-dev.20260622 with the one downloaded via the provided URL (on comparison the content seemed identical)

Both approaches lead to the same outcome.

I don't know if there is major difference how I tried to approach this but at least the result is different. The issue has been resolved partially.
The "libj2v8.so" is no longer a problem but "libimage_processing_util_jni.so" still is.
According to the dependency analysis "com.eclipsesource.j2v8:j2v8:6.2.1" has been updated to "6.3.4" but androidx.camera etc. is still used in version "1.1.0"

[elshadsm]

I suspect there is a plugin dependency, possibly a Cordova plugin, that uses an old version of androidx.camera.

You might need to upgrade this plugin version or update the androidx.camera version used by the plugin.

[mknauer]

In addition to what Elshad wrote: Maybe it is something as simple as the barcode scanner plugin? In my case the problem was solved by an upgrade to the last commit which uses the correct androidx.camera:camera-* versions.

[PatrickNass]

Like mentioned earlier, for the build i removed all plugins. Btw. I encountered a problem where when I removed all build hooks from the config.xml the build fails due to not reconizing different things anymore like the path structure. But this only as a side note.

Based on the dependecy analysis I did a deep dive into the tabris android platform code.
Those androidx dependencies are declared in
C:\Users\<user>\.tabris-cli\platforms\android\3.11.0-dev.20260622\templates\project\m2repository\com\eclipsesource\tabris\android\tabris\3.11.0\tabris-3.11.0.pom

and in C:\Users\<user>\.tabris-cli\platforms\android\3.11.0-dev.20260622\templates\project\m2repository\com\eclipsesource\tabris\android\tabris\3.11.0\tabris-3.11.0.module

        {

          "module": "camera-core",
          "version": {
            "requires": "1.1.0"
          }
        },
        {
          "group": "androidx.camera",
          "module": "camera-camera2",
          "version": {
            "requires": "1.1.0"
          }
        },
        {

          "version": {
            "requires": "1.1.0"
          }
        }

I manually updated those versions to 1.5.3

The next problem was

I updated the gradle version and ended up with different gradle/gradle-android version issue like (I have shortened the path with "<project_folder>"):

FAILURE: Build failed with an exception.

* Where:
Build file <project_folder>\build\cordova\platforms\android\app\build.gradle' line: 20

I managed to find a working combination by updating AGP_VERSION in C:\Users\<user>\Downloads\tabris-android-3.11.0-dev.20260622\tabris-android\framework\cdv-gradle-config-defaults.json to 8.9.0
and GRADLE_VERSION to 8.11.1

This lead to a successfull build but I want to point out following in the build log:

Starting a Gradle Daemon (subsequent builds will be faster)

I did not change it but MIN_BUILD_TOOLS_VERSION and SDK_VERSION should be updated as well.

I tried so many different things that I don't actually know if those following changes had any impact but I also updated
KOTLIN_VERSION to 2.3.21 (previously 1.9.24) and ANDROIDX_APP_COMPAT_VERSION to 1.7.1 (previously 1.6.1).

In the end I ended up with an .aab that looks like this, analysed by Android Studio:

Currently I don't know why a new library has been intruduced now but at least all libs are 16kb page size conform.

All in all this leads me to the conclusion that the problem still sits in com.eclipsesource.tabris.android:tabris:3.11.0 and the current nightly does not fix it.

Next I am trying to re-add all plugins.

[PatrickNass]

Update: After re-adding all used plugins the result is the same. This means the build is successful without adding other or old .so files to the build product. It looks good so far, all libraries are 16 KB page size conform.

The next step is to test the app and check if there are any side effects due to the updated KOTLIN, ANDROIDX_APP_COMPAT_VERSION or androidx.camera* libraries.

[elshadsm]

I just realized that the nightly Tabris Android platform is not compatible with the relevant Cordova Android platform, which does not currently support the Android 16 KB page size. We are currently working on this.

I will share the relevant Tabris Android platform with you in a couple of days. With this platform, you should not face any Android 16 KB page size support issues, and it will also be compatible with Android compile SDK 36 and target SDK 36 by default.
