App Bundle : couldn't find DSO to load: libfb.so

[JeromeCHA]

We tried to use App Bundle on our native Android app, but it crashes right after we launch the installed apks with the following error:

2019-08-27 16:48:27.394 E/com.facebook.soloader.NativeLibrary: Failed to load native lib: 
    java.lang.UnsatisfiedLinkError: couldn't find DSO to load: libfb.so
        at com.facebook.soloader.SoLoader.loadLibraryBySoName(SoLoader.java:455)
        at com.facebook.soloader.SoLoader.loadLibrary(SoLoader.java:371)
        at com.facebook.soloader.SoLoader.loadLibrary(SoLoader.java:336)
        at com.facebook.soloader.NativeLibrary.loadLibraries(NativeLibrary.java:56)

        at com.facebook.crypto.Crypto.isAvailable(Crypto.java:57)

With apk, it works fine.

Even the "patched" here, on the merged PR, doesn't work for us #26

We've made some research and it looks like it is related to this issue, but we couldn't figure out how to fix it. facebook/react-native#23764
Should we have to wait until this issue is fixed? or does anyone know how to fix it?

Edit: We are using
implementation ("com.facebook.conceal:conceal:2.0.2@aar")

Thank you in advance :)

We have run into this as well.

[JeromeCHA]

Since It has been 1 week after I post this issue, does anyone know if they are working on it or not?

[victorlaerte]

We are also having this problem 😢

[oprisnik]

SoLoader 0.8.0 should fix this problem. We didn't release a Fresco version that bundles it yet, but you can force the version, see facebook/react-native#25490 (comment)

[victorlaerte]

@oprisnik is there any idea when a new version for com.facebook.conceal using 0.8.0 will be released?

[JeromeCHA]

I am also waiting for a newest version of com.facebook.conceal using 0.8.0 ^^

[oprisnik]

In the meantime, does forcing the SoLoader version to 0.8.0 not work for Conceal?

[IamMasterWayne]

+1

@oprisnik I tried, but I still have the same error. 😥
Does anyone have tried?

[victorlaerte]

@JeromeCHA yeah, it doesn't work. :(

[barnhill]

Any update on this?

[wooyukit]

same here

Any solution for this?

[barnhill]

They don't seem to support this any longer

[wooyukit]

😱
I am using Litho framework for my project so I must init soloader at beginning. 😩

[illwiz]

please release new conceal version that use the latest soloader, back to using apk :(

There is one optimisation that might still work (it does in my case), instead of using plain old fat apk. We may still use aab, but disable splitting by architecture. To do this, we have to add a bundle {} block within the android {} block in the build.gradle file:

bundle {
        language {
            enableSplit = false
        }
        density {
            enableSplit = true
        }
        abi {
            enableSplit = false
        }
    }

Of course, it's still just a workaround.

[barnhill]

This is not a workaround as some of us the major benefit of bundling would come from splitting by arch.

Yep, I know. I'm lucky that in my app the main benefit comes from splitting by resources. Another thought was, maybe it would be possible to still split by arch and everything, but keep a dependency (conceal in this case) fat (?). But I didn't pursue this further.

I'm working on getting rid of conceal now by replacing it with the AndroidX security lib. Brad Barnhill, MSN, RN [email protected]

Hi @barnhill,

Did you successfully migrate the library? How can we decrypt old data?

Is there a way to decrypt old data without Conceal lib?

[barnhill]

We left the conceal lib in and decrypted with it. Then we encrypted with Tink. After several months of converting in place we removed conceal.
