Happens with GluonFX 1.0.15 as well. Attach 4.0.15 works fine.

Can't upload an APK directly because the APKs that are produced are ~25MB from the get-go. Here is a share link: https://drive.google.com/file/d/1znRO8LCCoUwaYk2fp1tczJfZLXUXzuhu/view?usp=sharing

On OnePlus 8T with Android 12 there is no issue.

[jperedadnr]

It seems it fails only for Android 8, which might indicate that the call:

Util.clipboard = (ClipboardManager) activity.getSystemService(Context.CLIPBOARD_SERVICE);

requires some extra code for such Android level.

See related https://stackoverflow.com/questions/9027629/android-clipboard-code-that-works-on-all-api-levels/12946228#12946228

[nlisker]

I have just tested with Attach 4.0.18 and the problem still exists. We can't upgrade attach beyond 4.0.15 without breaking our Android 8 clients.

[jperedadnr]

@nlisker Is it possible that you build yourself Attach with this patch and test?

(with the Android toolchain installed, run sh gradlew build publishToMavenLocal to build and install Attach 4.0.19-SNAPSHOT)

[nlisker]

Where do I downloaded the toolchain from? There are the command line tools at https://developer.android.com/studio/index.html#command-line-tools-only and the NDK at https://developer.android.com/ndk/downloads. Neither contain the required android.jar.

[jperedadnr]

If you have the Android SDK/NDK for GluonFX/Substrate, then that's all you need. Just make sure you have ANDROID_SDK and ANDROID_NDK defined.

[nlisker]

I have the ones from the links above. What are the ones for GluonFX/Substrate? Are there instructions somewhere? Attach's README doesn't show any.

[jperedadnr]

If you deploy for Android with the GluonFX plugin on Linux, you need ANDROID_SDK and ANDROID_NDK. If you don't set them, the plugin manages to download and install them for you, at ~/.gluon/substrate/Android

Then, to build Attach, you would just need to set: ANDROID_SDK=/your user path/.gluon/substrate/Android ANDROID_NDK=/your user path/.gluon/substrate/Android/ndk

[nlisker]

Ah, alright. I use WSL. I'll try it out later.

[nlisker]

Thanks, I set the env variables. Now I'm getting an error with the new code in Util:

error: local variable activity is accessed from within inner class; needs to be declared final

   Util.clipboard = (ClipboardManager) activity.getSystemService(Context.CLIPBOARD_SERVICE);
                                       ^

[jperedadnr]

That shouldn’t happen, set JAVA_HOME to JDK 11 or 17? Check also the GitHub action workflow

[nlisker]

JAVA_HOME is set to 17 and java --version gives openjdk 17.0.3 2022-04-19.

[nlisker]

I tried ./gradlew -i nativeBuild as the action workflow does, same issue.

[nlisker]

I deleted some caches and restarted the gradle daemon. Now I'm getting another error during :accelerometer:androidBuild:

Indeed, in Java 17 that option was removed. Any idea where it comes from?

[jperedadnr]

See https://github.com/gluonhq/attach/blob/master/gradle/android_project/gradle.properties#L3 you can simply edit the file and remove -XX:MaxPermSize=1024m, or use JDK 11.

[nlisker]

Thanks, I managed to build Attach and build the client using the snapshot version. Unfortunately, I'm still getting a black screen, and after a few seconds I get a message that the app has stopped.

[jperedadnr]

Can you post the stack trace from logcat?

[nlisker]

This looks like the relevant part, if you need something before or after I will paste here.

[jperedadnr]

Hmm, looks like the same logcat you already posted earlier:

at void com.gluonhq.helloandroid.Util.<init>(android.app.Activity) (Util.java:53)

means that there are no changes in Util... Are you sure you are using the Attach snapshot? Did you build, package and deploy again?

[nlisker]

I have <attach-version>4.0.19-SNAPSHOT</attach-version> in my pom and I ran mvn -Pandroid gluonfx:build gluonfx:package. I can also see in the local maven repository that the 4.0.19-SNAPSHOT directory was created after I ran the publishToMavenLocal command on attach. I can try to clean / delete caches.

[jperedadnr]

Just to be sure, add some printouts (Log.v(TAG, "Util <init> 1");, Log.v(TAG, "Util <init> 2"); ... ) and see that you get them before the exception?

[nlisker]

The error with the non-final variable repeats after I clear the caches and builds. If I try to build again then it somehow succeeds. However, I noticed that when building the application, it takes the 4.0.19-SNAPSHOT build from the online repository, which is why the JNI error repeated itself. I tried to change the gradle.properties version to 4.0.20-SNAPSHOT to make sure it doesn't come from a remote repo. Then I built the client again and got this exception:

So I suspect there really is a problem in building Util.

I've raised a PR for this #361 Once merged you will be able to test the snapshot from Sonatype.

[nlisker]

Is 4.0.19-SNAPSHOT updated or should I wait some time?

[jperedadnr]

Just wait until the github action finishes (10 minutes or so), then it will be ready from Sonatype.

[nlisker]

I delete my maven cache and cleaned the project. Now when I run mvn -Pandroid gluonfx:build gluonfx:package using 4.0.19-SNAPSHOT I get this error, which I have never gotten before:

[jperedadnr]

Hmm, never seen that one either.

(Unrelated probably, why are you still with plugin 1.0.15? 1.0.18 is the latest one)

Next: what is your maven version? there is an issue with 3.9.0+ and the (latest) plugin requires a lower version, like 3.8.8.

Have you checked that the 4.0.19-SNAPSHOT files in your .m2 come from Sonatype?

Have you checked your pom for duplicated runtime dependency entries?

[nlisker]

(Unrelated probably, why are you still with plugin 1.0.15? 1.0.18 is the latest one)

I'm using the maven versions plugin that is supposed to tell me when an updated version of a plugin exists. It insists that 1.0.15 is the latest. I changed it to 1.0.18.

Next: what is your maven version? there is an issue with 3.9.0+ and the (latest) plugin requires a lower version, like 3.8.8.

3.8.6

Have you checked that the 4.0.19-SNAPSHOT files in your .m2 come from Sonatype?

I deleted the attach cache there, so I don't know where else it could come from. The _remote.repositories file (under util, for example) which is supposed to contain that info is

#NOTE: This is a Maven Resolver internal implementation file, its format can be changed without prior notice.
#Fri May 05 14:05:23 IDT 2023
util-4.0.19-20230505.104751-6.pom>snapshot=
util-4.0.19-20230505.104751-6.jar>snapshot=

so I'm not sure where it's from.

Have you checked your pom for duplicated runtime dependency entries?

Yes. If I change the attach version to 4.0.15 everything builds fine. The pom is the same as I posted above, only with some version changes.

[jperedadnr]

https://github.com/gluonhq/gluonfx-maven-plugin and https://central.sonatype.com/search?q=g:com.gluonhq%20%20a:gluonfx-maven-plugin&smo=true show 1.0.18, not sure about what that plugin is doing.

Can you post

mvn dependency:tree

(see if there are duplicated entries for com.gluonhq.attach:display)

Also, can you try

mvn -U -Pandroid gluonfx:build gluonfx:package

If it builds fine, uninstall the app from your mobile before installing again.

[nlisker]

[jperedadnr]

Nothing wrong there.

The snapshot seems fine: 20230505.104751-6 is the latest version, see: https://oss.sonatype.org/content/repositories/snapshots/com/gluonhq/attach/display/4.0.19-SNAPSHOT/display-4.0.19-20230505.104751-6.jar

I've clear my Attach cache as well, building a regular HelloGluon (with a TextField control) for Android works fine for me. Can you maybe try that?

[nlisker]

I cloned HelloGluon, changed to attach 4.0.19-SNAPSHOT and added the snapshot repository. It built and ran fine. Then I built my project without any changes and it also built and ran fine (including the clipboard). I'm guessing the HelloGluon build unstuck something, but I have no idea what since I cleaned everything previously as well.

So it looks like the problem is resolved. Thanks for all the help!
