java.lang.UnsatisfiedLinkError exception in AndroidUtils_setContext function in MapView #511

AbolfaZlRezaEe · 2022-07-23T07:51:33Z

We have an exception in our application that is from CART SDK. unfortunately, we couldn't find any scenario for reproducing this crash on our phones. the stack trace that Google console gives us is this:

in CARTO SDK version 4.3.5

java.lang.UnsatisfiedLinkError:

  at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:1130)

this crash happens around 86K for our users! and that isn't good for our application.
also, we found an issue that mentions this exception in 2019 in this link with some details. but there is still no good solution for this issue yet.
we found this issue in these SDKs much more than the others:

these informations are from Google Play Console!

Android 11(SDK 30) -> 11253 crashes - 40.5%
Android 12(SDK 31) -> 4590 crashes - 16.5%
Android 10(SDK 29) -> 4086 crashes - 14.7%
Android 8.1(SDK 27) -> 2279 crashes - 8.2%
and ...

also, this crash happens much more in these devices:

Samsung Galaxy A12
Samsung Galaxy J2 core
Samsung Galaxy M01s
Samsung Galaxy A32
Samsung Galaxy A13
Samsung Galaxy A10

it's better to mention that we have some crashes on Xiaomi phones but crashes in Samsung phones are much more than the Xiaomi phones.

We highly need help for this crash and we have no idea that this crash when happening and why it happens. can somebody help us?

Thanks for reporting this. SDK tries to load native part of the SDK automatically before any MapView method is accessed, but in this particular case the loading has failed. Why this happens is unclear, as the device list contains very common devices plus the Android versions are all relatively new. My guess is that this is related to APK packing but I can not confirm this for sure. To get further insights I suggest adding the following snippet BEFORE calling MapView.registerLicense:

        try {
            System.loadLibrary("carto_mobile_sdk");
        } catch (Throwable t) {
            // TODO: log the details of thrown exceptions to some central repository
        }

This snippet tries to manually preload the native part and will log the issues. Once you have some additional details from the logs, please share them with us.

AbolfaZlRezaEe · 2022-07-26T07:55:21Z

but in the MapView class we load SDK like this before we do anything...

static {
        try {
            System.loadLibrary("carto_mobile_sdk");
            AndroidUtils.attachJVM(MapView.class);
        } catch (Throwable t) {
            android.util.Log.e("carto_mobile_sdk", "Failed to initialize Carto Mobile Maps SDK, native .so library failed to load?", t);
        }
    }

why we would load it again before registerLicense function?

mtehver · 2022-07-26T08:30:25Z

@AbolfaZlRezaEe Because it fails but the logging of the event is 'local' and you do not see the message. The beforehand loading is just for getting the exception info to a server so we can see the details.

AbolfaZlRezaEe · 2022-07-26T08:36:36Z

Ok. We will do this for our next application version and report the issue here(if we see it in the console)

AbolfaZlRezaEe · 2022-08-22T06:11:51Z

Well, after a release that We had, We received these stack traces from our crash report. We hope that these are good points enough to catch this exception:

it's good to mention that some of these exceptions same as each other on some points. but We preferred to send all of them to you.

@AbolfaZlRezaEe It seems that there are packaging issues, as the native part of the SDK can not be loaded. Can you share your build.gradle file (assuming you are using Android Studio/gradle)?

AbolfaZlRezaEe · 2022-08-27T06:47:21Z

@mtehver I think it's good to mention all of our steps for building and using Carto in our application:

for building Carto-SDK, every time We wanna build the SDK, We use this command:

python{YOUR_PYTHON_VERSION} build-android.py --profile standard --build-aar --configuration Release --gradle {YOUR_GRADLE_DIRECTORY}

after that, We use two ways to import aar file into the project. first, with putting aar file into libs section, so the code in build.gradle file is like this:

dependencies {
    implementation fileTree(dir: 'libs')
    implementation files('libs/carto-4.3.5.aar')
}

or with our Maven repository. for using that, we edited the build-android.py file and changed the Gradle section into this:

if not gradle(args, '%s/scripts' % baseDir,
    '-p', 'android',
    '--project-cache-dir', buildDir,
    '--gradle-user-home', '%s/gradle' % buildDir,
    'assembleRelease'
    'artifactoryPublish'
  ):
    return False

also, we changed the publish.gradle file. but it doesn't matter right now for our problem I think. so, after we publish the aar file and sent it to our Maven, we import SDK into our project like other libraries:

dependencies {
implementation 'org.projects:carto:4.4.3.'
}

after We build the application for the Store, We have four libs files of CARTO-SDK .so file in our application. like this:

We have a guess that the Store sometimes gives the wrong architecture to the users and this is one of the problems that these exceptions are thrown. but we are not sure. so after all these, any idea?

mtehver · 2022-09-04T13:00:43Z

@AbolfaZlRezaEe Looks good based on the description, all architectures seems to be present in your APK. No idea why the issue occurs on on some devices. One thing you can try - experiment with 'split ABI' settings (described here: https://developer.android.com/studio/build/configure-apk-splits).
