Few months since last Tracking slipped NPE and here we go again:

• same user reported;
• same scenario (code that handles a lot of NPE in try/catch);
• this time with Crashlytics.

Time for dissection…

There was a report in MobiVM matrix channel for crash that is happening only during running under debugger:

java.lang.NoClassDefFoundError: Could not initialize class com.sample.mobile.ios.network.RoboVmNetzwerkStatusController
        at com.sample.mobile.ios.Main.didFinishLaunching(Main.java:208)

TLTR: Fix and workaround

AltPods were updated to v1.53.0-SNAPSHOT to sync with recent releases.

Updated pods (ones with API changed)

• AppLovinSDK v13.3.1 -> v13.4.0
• BranchMetrics v3.12.2 -> v3.13.0
• IronSource v8.10.0 -> v8.11.0

Updates without any API change

• Google Mobile Ads updated to v12.8.0 -> v12.9.0
• Firebase updated to v12.1.0 -> v12.2.0

• UnityAds updated: v4.16.0 -> v4.16.1

• These pods were pushed to https://central.sonatype.com/repository/maven-snapshots/ maven repo under 1.53.0-SNAPSHOTS version. Source code @github

Updates are not fully tested, please open issue if bug found.

issue#813 was reported as an issue with storekit2 bindings.

Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘+[missing_RvmProduct_PurchaseOption appAccountToken:]: unrecognized selector sent to class 0x1332748a0’

With comments that simulator works but app fails on real device.
Lets investigate.

Tom-ski have reported production level crash caused by EXC_BAD_ACCESS by java code inside try/catch block. It is well known issue of code like this:

    public static void sayHello() {
        String s = null;
        try {
            s.toString();
        } catch (NullPointerException e) {
            e.printStackTrace();
        }
    }

caused by third party code that messes with SIGSEGV signal handler and makes it not accessible to RoboVM.

Breaking changes

AdMob is not longer a part of Firebase. It was moved out of Firebase package so its artifact id is changed:

• admob -> io.github.dkimitsa.robovm:robopods-google-mobile-ads-ios
• ump -> io.github.dkimitsa.robovm:robopods-google-ump-ios
• DynamicLinks removed as not available in Firebase anymore.

Silly typo fixed in CleverAds class package name: package org.robovm.pods.cleverads.* now.

Updated pods (ones with API changed)

RoboVM can call native libraries written in ObjectiveC using ObjectiveC Runtime. Same is possible for Swift libraries if api is exposed as @objc. In this case ObjectiveC compatible API are provided that can be used with RoboVM.
In case of pure Swift code there is no Objc compatible API RoboVM can work with.
Same thing affects other tools:

Kotlin:

A Swift library can be used in Kotlin code if its API is exported to Objective-C with @objc. Pure Swift modules are not yet supported.

Xamarin

If the header doesn’t exist or has an incomplete public interface (for example, you don’t see classes/members) you have two options: -Update the Swift source code to generate the header and mark the required members with @objc attribute

• Build a proxy framework where you control the public interface and proxy all the calls to underlying framework

In every case it requires API to be available for usage in ObjectiveC world. And it is not – a ObjC compatible wrapper to be created and used with RoboVM/Kotlin/Xamarin.

While Intellij Idea’s code base is migrating to kotlin, its UI is migrated from Swing/AWT to their own Kotlin UI DSL implementation similar to Kotlin compose.
Sadly there is no preview panel available for this kind of code (There was semi-official plugin but it’s not supported anymore.

Let get few hacks to have it available:
