Android Dev - Weekly Who's Hiring Thread - June 21, 2021

I am an indie developer, and use Java in my project. Recently, my DB used for listing a recycler view has grown a lot, and it has a lot of latency on loading the view. I was thinking of implementing paging, and stumbled on the paging3 library provided by Jetpack.

But, I couldn't find any good tutorials to implement the same in Java (only room, no network involved). I tried to hack together from what was available from Google, but that doesn't seem to be working. Is there no hope for Java here?

Would appreciate any help here!

Using constructor RxController I can't use coroutine nor view model

Posted: 21 Jun 2021 08:06 AM PDT

I got to a project where they use RxController on the library "com.bluelinelabs.conductor"

I want to do the MVVM architecture, but using RxController doesn't have the "viewLifecycleOwner", so I cannot use this on my code.

viewModel.employee!!.observe(viewLifecycleOwner,{ mAdapter.notifyDataSetChanged() })
Any suggestions where I don't have to switch everything to fragments?

Thanks,

Is there a better image color palette API?

Posted: 21 Jun 2021 06:19 AM PDT

I've been inspired by the new material you designs I've seen, and at the same time am learning android development with compose.

One of the big things I'm looking to do is to dynamically theme my app based on user supplied images, aiming for something along the lines of this. I've been using the native google image palette API, but to be honest the colors it generates are very limited and bland.

Does anyone know of a better palette generating API, not necessarily first party?

Thanks!

How much do you believe your app changed in the last year?

Posted: 21 Jun 2021 02:59 AM PDT

I'm making research to check how much an app changed in the last year, to help developers and managers better understand how the decisions that you make today will or not impact the future.

I will be also sharing the results if you can just spend 1 minute and choose some options.

No personal data is mandatory and I will put back here the result.

Linking static libraries to Android.mk - ld undefined symbol is found in the static lib?

Posted: 20 Jun 2021 02:56 PM PDT

Getting a weird error. It seems like the `undefined symbol` is actually found in the static library? Why is it not recognizing this?

ld: error: undefined symbol: ACE_Time_Value::ACE_Time_Value(long, long) >>> referenced by VrCubeWorld_Framework.cpp:241 (jni/../../../Src/VrCubeWorld_Framework.cpp:241) >>> /home/smiller/Development/Vandy/Term3/VR/ovr_strip1/VrSamples/VrCubeWorld_Framework/Projects/Android/build/intermediates/ndkBuild/release/obj/local/arm64-v8a/objs/vrcubeworldfw/__/__/__/Src/VrCubeWorld_Framework.o:(OVRFW::VrCubeWorld::AppInit(OVRFW::ovrAppContext const*)) >>> did you mean: ACE_Time_Value::ACE_Time_Value(long, long) >>> defined in: /home/smiller/Development/Vandy/Term3/VR/ovr_strip1/VrSamples/VrCubeWorld_Framework/Projects/Android/jni/../../../../../3rdParty/ACE_wrappers/build/target/lib/libTAO.a(ORB_Core.o) clang++: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [/home/smiller/Android/Sdk/ndk/22.0.7026061/build/core/build-binary.mk:728: /home/smiller/Development/Vandy/Term3/VR/ovr_strip1/VrSamples/VrCubeWorld_Framework/Projects/Android/build/intermediates/ndkBuild/release/obj/local/arm64-v8a/libvrcubeworldfw.so] Error 1

I've posted my Android.mk and some other things at StackOverflow. Any help appreciated!! https://stackoverflow.com/questions/68060324/oculus-sdk-android-ndk-linking-error-1-did-you-mean-same-as-used-symbol
