What's the issue?

With 1.3.5 and 1.3.6 I am getting java.lang.UnsatisfiedLinkError: dlopen failed: library "libmmkv.so" not found

We are using with multi process mode, here is the line where it fails:

private val mmkv: MMKV = MMKV.initialize(appContext).run { MMKV.mmkvWithID(MMKV_FILE_NAME, MMKV.MULTI_PROCESS_MODE) }

Note that there are no such issues when using 1.3.4.

What's the log of MMKV when that happened?

Here is the exception we are getting, happens when app starts

1.3.5+ drop x86 and armV7.

lingol commented 3 months ago

1.3.5+ drop x86 and armV7.

That is right. You have two options. Either add armv8 support or build armv7 binary of MMKV by yourself.

dimitar71 commented 3 months ago

Thank you for your quick responses. I am going to do that and will inform here of the success/failure.

Using it in a library module, we are expecting this to work out of the box. It is failing when compiling against a vanilla Chromecast device after all, not some exotic unknown thingie done in a mom-and-pop basement/garage.

Or, to have a short tutorial/steps what needs to be done - with or w/o building from sources and alike. I personally think there should be an extensive section somewhere there - https://github.com/Tencent/MMKV/wiki/android_setup, with screenshots and all.

Other than this recent problem - an excellent, if not best and in its own league, library.

And finally, a suggestion - if possible, to have arm.. .so part of Assets section of every new release? It will help a lot!

OK, using the steps in https://github.com/Tencent/MMKV/wiki/android_setup > Build From source and it fails.

Using Android Studio Koala | 2024.1.1.

Please provide full steps guide if possible, including Android Studio version, Gradle version, Java version, etc. for the ability to compile against your sources.

In the meantime, back to 1.3.4.

This is using default project:

And this is after upgrading Gradle to 7.5

After some tweaking, I could build from sources using latest Android Studio, Gradle and Kotlin. There are some caveats, up to you to use these findings or not.

Attached is MMKV-1.3.6/Android/MMKV folder only as a zip, with the changes which allow me to build and use all arm additions.

The removal of 32bit architecture is a well thought decision and will not be reversed.

Upon your changes, the changes to the abi filter is essential. Others are just environmental differences.

I shall mention the steps to build a armv7 binary in the wiki if I haven't already done so.

lingol commented 2 months ago

v1.3.7 LTS has just been release.

This Long Term Support (LTS) release primarily reintroduces support for the ARMv7 architecture and lowers the minimum SDK version requirement to 21. Please note that only critical bug fixes will be applied to the 1.3.x series.

New features will be introduced in version 2.0 and later, which will discontinue support for 32-bit architectures and raise the minimum SDK version requirement to 23.

One more thing, the wiki has been updated on building from source on Android. It will be helpful once we upgrade to v2.0+. https://github.com/Tencent/MMKV/wiki/android_setup
