Using an app bundle I get UnsatisfiedLinkError for <1% of users

Issue

I'm trying to use the new Android App Bundles.

I run some test locally on my devices, and everything works correctly. However, once deployed to production, I am starting to see a few errors like this:

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/xyz/base.apk"],nativeLibraryDirectories=[/data/app/xyz/lib/arm, /vendor/lib, /system/lib]]] couldn't find "libsqlite3x.so"
java.lang.Runtime.loadLibrary (Runtime.java)
java.lang.System.loadLibrary (System.java)
io.requery.android.database.sqlite.SQLiteDatabase.<clinit> (SQLiteDatabase.java:86)
io.requery.android.database.sqlite.SQLiteOpenHelper.getDatabaseLocked (SQLiteOpenHelper.java:241)
io.requery.android.database.sqlite.SQLiteOpenHelper.getReadableDatabase (SQLiteOpenHelper.java:199)
...

The error states that a library I'm using (requery/sqlite-android) cannot find the .so file that it needs. This seems strange, since I checked with bundletool, and in every APK the file .so is there.

The error happens on two devices: a Samsung Galaxy Note 7 and a TECNO-J8, running Android 6 and 5 respectively.

According to the Play Store, the error happens for app installed through Google Play, so I doubt the error is related to APK sideloading.

The generated APK bundle includes splits for the following architectures:

• splits\base-armeabi_v7a.apk
• splits\base-mips.apk
• splits\base-arm64_v8a.apk
• splits\base-x86_64.apk
• splits\base-x86.apk

Do you have any hints?

Solution

Even though the installs are reported from Play, this information can easily be spoofed when using adb (which some users have learnt to do for some reason that I don't quite get yet). Those crashes very likely come from sideloads which don't install the config splits in spite of the appearances.
