[React Native] Add 64 bit support for Android

[kneth]

From August 1, 2019 Google Play will not accept apps with 32 bit only .so files. Currently, we only compile our React Native (Android) .so for ARMv7 and x86, but we should in good time provide 64 bit .so files too.

React Native (Android) added support for ARM64-v8a and x86-64 recently: facebook/react-native#18754.

Thanks for raising this, appreciated.

[radeno]

@kneth i do not force to anyone but i think this should be priority.
3 months after first React Native RC version we get support for 0.58 what was big step forward and i really appreciate it and i can says many developers like it and we are thank you for it ♥️. But it was just partial support of RN 0.58 because it brings support for Android ARM 64bit app variations.

And version 0.59 is behind door. This version should be compatible with Realm which will be great, but again, it enabling support even for x86_64. Android platform is involving in RN very quick.

But another great change for RN0.60 (probability is very high) is that it replaces very unfriendly import Xcode libs with Cocoapods. And it will be default for all new projects.

Do you have any plan how to be complatible with RN in very close time when new RN version will be released?

[kneth]

@radeno Thanks for giving us the executive summary of RN roadmap. Every RN version seems to break something, so it is hard to stay on top of it.

We are currently refactoring our code base and upgrading the Android NDK. Once those two tasks are completed, we can begin to look forward. Adding 64 bit support for Android should be trivial. Better Cocoapods support sounds great.

[bmunkholm]

I would also add, that we are very appreciative of PR's :-) and encourage the community to help in any way possible. Even if that's not a PR, making issues with details of upcoming breaking changes is also helpful.

Marking as blocked as we are waiting for React Native 0.59 before we can enable this: facebook/react-native#2814 (comment)

[radeno]

@cmelchior 0.59-rc3 release is one day old. It is probably last RC before production or will be rc4 with some small fixes. If this commit facebook/react-native@f3e5cce will not be merged into 0.59 (i hope not, it is too big change for current state) then rc3 is quite solid stable without such big changes before release production.

[radeno]

@cmelchior my mistake. It is already in 0.59. So all big changes with JSI/JNI for Android looks like done.

[kneth]

In facebook/react-native@f3e5cce React Native is changing to clang and libc++, I suggest that we wait until we have upgraded to a recent Android NDK.

[zaguiini]

RN is already at 0.59. It's stable!

[diegolmello]

Can we get more attention on this?
Realm just released support for RN 0.58 and became outdated two weeks after that with RN 0.59.

[Mscynol]

realm is not support 0.59(RN) now

[IamStephan]

realm is not support 0.59(RN) now

I'm confused...
Are you saying that it does work or not?

[kneth]

I believe that RN 0.59 requires some changes that we haven't had time for yet.

[FunkyLambda]

I think people are getting a bit off-topic here. The original issue was support for 64-bit, not RN 0.59. I realise they are very closely related, but at the same time, as @cmelchior stated in #2282:

64 bit support seems to require changes to https://github.com/realm/realm-js/blob/master/react-native/android/src/main/jni/Application.mk#L3 and https://github.com/realm/realm-js/blob/master/react-native/android/build.gradle#L230, but this does not need to be part of the same PR as 0.59 support

[diegolmello]

@FunkyLambda I feel you, but one of the bigger new features of RN 0.59 is 64-bit support.
Of course we can change build.gradle architectures to support 32-bit only, but I think you'll agree this is not what RN 0.59 support means.

[radeno]

@diegolmello 64bit arrived with RN 0.58, 0.59 brings new JSI and compiler.
So i think this topic is about 64-bit support only. RealmJS works with RN 0.59.

@radeno http://facebook.github.io/react-native/blog/2019/03/12/releasing-react-native-059#updated-jsc-means-performance-gains-and-64-bit-support-on-android 🤔

[radeno]

@diegolmello https://github.com/facebook/react-native/blob/0.58-stable/local-cli/templates/HelloWorld/android/app/build.gradle branch 0.58

[diegolmello]

@diegolmello https://github.com/facebook/react-native/blob/0.58-stable/local-cli/templates/HelloWorld/android/app/build.gradle branch 0.58

@radeno x86_64 is missing, but I don't want to argue about it.

[radeno]

@diegolmello x86_64 is intel/amd processor. AMR7/8 is 99,9% all mobile devices.

[BrandonSmith]

@PanRada @TheusBrz Ensure your Android app/build.gradle is only building for 32-bit architectures.

React Native 0.58 is when 64-bit first landed. So comparing the diff between the generated app/build.gradle, ensure your's uses 0.57 values...

android {
...
  splits {
    abi {
      ...
      include "armeabi-v7a", "x86"
      ...
  }
...
}

Ensure that "arm64-v8a", "x86-64" are not in the list.

[theus-brz]

@BrandonSmith become able to run my app on Android but it breaks other functionalities and break my iOS app... I'm very excited to use RealmDB but I'm feeling that is not the moment... I'm not an excellent developer yet and my projects deliver dates are close... I plan to move to SQLite for now..

[cristianoccazinsp]

Any updates on this? Removing "x86_64" from gradle build files is not working.

Edit. Looks like I had to also add:
ndk {
abiFilters "armeabi-v7a", "x86"
}

This looks really bad, forcing 32 bits just because a library. What would be the side effects of this?

Edit 2: Using the above although allowed the app to run, it is now raising errors related to touch events that never happened before. I guess I will be staying away from Realm as well. Shame since it seemed very good when testing on other devices.

[nirinchev]

Thank you for relaying your concerns. While I understand that this is an issue many care about, flooding the comments with "+1", "I want this fixed now!!11", etc. is not productive. When we have more information to share, we are going to update the issue.

[theus-brz]

@nirinchev I'm anxious to start using Realm, I'll keep an eye on this issue to get news.

I wish you a good coding :)

[Eyesonly88]

Hey @nirinchev, I think people wanna know if this will be resolved before the deadline of 1st of August 2019 or not?

[cmelchior]

It will

[trungthanhnt]

Does anybody have a hot fix for arm64bit?
I can build but it crash on Android 64bits . Best Regards

[bmunkholm]

It's being worked on now here: #2366.

[kneth]

@trungthanhnt You need to combine #2221 (comment) and #2221 (comment) until we support 64 bit.

[nhachicha]

this is fixed in v2.28.0

[diegolmello]

Nice work, @nhachicha @kneth! 👏👏👏

[ferrannp]

Thank you very much to fix this!

[kneth]

We hear about crashes - most likely due to facebook/react-native#24261 - on Samsung devices.

[anshul-kai]

Has there been a decision on which version of react-native will this be packaged in? Thank you!

[kneth]

@a-koka I don't think the React Native developers have a fix ready yet.

[deepakverma4]

anyway to support 64bit architecture in 0.55.4?

[kneth]

@deepakverma4 You will need RN v0.59 (https://facebook.github.io/react-native/blog/2019/03/12/releasing-react-native-059)

[0x01001]

still crash on v3.5.0 RN v0.61.5
