If you were having this issue, then yes, you should be removing 'android.bundle.enableUncompressedNativeLibs=false' from the gradle.properties.

The size of the APK being bigger because of the native libs not being compressed is (counter-intuitively) a benefit for your users: the Android platform will be able to read the native libs directly from the APK without having to uncompress them on the device first during the installation which leads to your app having a smaller footprint on the device. The APK is also compressed when it's served from the Play Store to users and the compression is usually better when the native libs are uncompressed, which leads to smaller download sizes as well. Overall, smaller download size and smaller size on device which is a win-win for end-users: the only thing that's bigger is the file you upload to the Play Console.

Could you please share on what device you have seen this issue happen? (Brand, Model, Android API)

That property is for Bundles only indeed.

/mnt/asec/ suggests that this is related to ASEC external storage as well though.

Do you have the property android:extractNativeLibs=false set in your AndroidManifest.xml? If so, removing it could possibly fix the issue (since that's effectively what the enableUncompressedNativeLibs property is enabling for Bundles).

Aha, that probably explains it, yes.

What devices on Android 9 please? Do you have a list? It would help us so we can reach out to OEMs so they can fix those devices via OTA updates.

For us, data from the past 7 days:

Android 10: <1% Android 9: 94% Android 8: 5%

LG: 91%

• G6: 21%
• V40 ThinQ: 13%
• LG G7 ThinQ: 10%
• other (15 devices): 47%
• • LG Stylo 4
• • LG Premier Pro
• • LG Q7+
• • LG G7 ThinQ
• • LG V35 ThinQ
• • LG G6
• • V30
• • LG G6
• • LG Aristo 3+

95% of the time it's happening in the background. Unfortunately, I don't have the stat breakdown of which OEM devices are on Android 9.

We do not have extractNativeLibs or enableUncompressedNativeLibs set.

Having issues as well on my bundled app. Several reports from Samsung devices on Android 9.0.

Caused by: java.lang.UnsatisfiedLinkError: dlopen failed: couldn't map "/mnt/asec/PKG/split_config.arm64_v8a.apk!/lib/arm64-v8a/libFOO.so" segment 1: Permission denied

Samsung: SM-N9500 SM-M305F

Too bad, I liked the idea to have smaller install size, but this clearly should not be recommended.

I can confirm it for an APK (non-bundle) app not setting android:extractNativeLibs="true" on the following devices (according to Firebase):

• LG G7 ThinQ
• LG G6
• LG G5

In our case this is exclusive to LG devices. Amongst those, 90% of crashes happen with Android 9, only device shows the issue with Android 8.0.0.

I think your sentence needs to be corrected so we can understand:

Amongst those, 90% of crashes happen with Android 9, only device shows the issue with Android 8.0.0.

As is, it looks like you might have forgotten "one" between "only" and "device" but I can't be sure.

Reopening for LG devices.

Having issues as well on our bundled app. enableUncompressedNativeLibs set to false.

Stack trace we are seeing in Firebase reports:

Caused by java.lang.UnsatisfiedLinkError: dlopen failed: couldn't map "/mnt/asec/com.---.---/split_config.arm64_v8a.apk!/lib/arm64-v8a/libshinobicharts-android.so" segment 0: Permission denied
       at java.lang.Runtime.loadLibrary0(Runtime.java:1016)
       at java.lang.System.loadLibrary(System.java:1669)

Affected devices:

LG - 80%

Samsung - 20%.

no reports for other devices.

Affected android versions:

Android 7, 8, 9

From the provided stack trace it looks like Android tries to read native library from the APK instead of file system location. Can you ensure that android:extractNativeLibs is not set in Android manifest and gradle property android.bundle.enableUncompressedNativeLibs is set to false?

android.bundle.enableUncompressedNativeLibs=false - that's correct

regarding android:extractNativeLibs: we are not setting it explicitly, but as i can see from Merged Manifest it is set to false which is default value for gradle plugin 4.0.0 as i understood.
