Thanks for changes you made for 16KB support in version 2.2.4 , still require some changes that you have to update native android code side as well. Then only another_brother sdk will support 16KB support. Could you pls help in that?

@CodeMinion : Hey Frank, unfortunately we are facing the same issue with the latest version (v2.2.4). Is there anything we can assist with?

See APK analyzer, in x86_64 lib the libcreatedata.so is still problematic unfortunately

[swapnilparmar-git]

@CodeMinion Hey Thank you for your time.

@CodeMinion libcreatedata.so show error means, still there are problems in dependancy whichever you have used in your native code.

(1)Could you please update your native android source code of "Android Printer SDK ".
(2)You may also update and check your gradle.properties :-
distributionUrl=https://services.gradle.org/distributions/gradle-8.9-all.zip ///(with this) .
(3) Update also JDK_21 if you may have used older one.
(4)Update .so file using following command -

 cmake -B build -S . \
 -DANDROID_ABI=arm64-v8a \
 -DANDROID_PLATFORM=android-34 \
 -DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZE=ON \
 -DCMAKE_TOOLCHAIN_FILE=$NDK_PATH/build/cmake/android.toolchain.cmake      

and run this >> cmake --build build --target install .
This will create new .so file and paste it at this location > another_brother/android/src/main/jniLibs/arm64-v8a/libcreatedata.so

This 4 things we may need to update and check that 16KB compatible or not.

Hey — we’re hitting the same 16 KB page size, and it’s pretty blocking our release.
Is there any update or ETA on a fix?

I'm also facing the same issue.

for x86_64

libcreatedata.so is unaligned.

@CodeMinion Hey, Could you please configure your native android source code of "Android Printer SDK " for 16KB support. May be it will solve problem of wifi printer. Right now as we can see changes needed for flutter code is already configured.

@CodeMinion, are there any updates regarding the issue? We are getting close to the Google Play's deadline.

[CodeMinion]

Hello @swapnilparmar-git ,

Unfortunately we don't have much bandwidth for large changes at this time, but if you can point us to the "Android Printer SDK" you are referring to we can take a look at what level of effort it would require to update and let you know.

Thanks in advance,

As a workaround for now we just removed the another_brother x86_64 lib from our build. This means that the package will not work (and most probably crush the app) on x86 and x64 platforms. For us, we saw that there are 0 devices with this platform that are using our app, so it is ok for now.

If you want to do the same, you can go to android -> app -> build.gradle and edit the android section:

  android {
    namespace = "..."
    compileSdkVersion 35

    //* Removes libcreatedata.so for android x86_64 until the issue is fixed
    packagingOptions {
        jniLibs {
            excludes += ["**/x86_64/libcreatedata.so"]
        }
    }
