Play Console stacktrace for TiJSService

I have an app with 100.000+ users and since Android 7 begun rolling out this stacktrace have begun showing up (only reported for Android 7.0). I use Ti SDK 5.5.1
It's being reported for: ti.modules.titanium.android.TiJSService.start

Anyone who can point in any direction? I'm kinda lost as to the cause of this.

Unity Android 6 Fragment$InstantiationException

recently (past few weeks maybe) most of the android 6 users of my app started to suffer from crashes. UnityPlayerActivity failed to start with exception logged: android.app.Fragment$InstantiationException.
Stack trace:

Initially my first thought was permissions problem but I can't reproduce this error on any of my android 6 devices even if I deny permission (WRITE_EXTERNAL_STORAGE).
Is there is any workaround for this problem(if this problem is a common for Unity on Android 6)?
Thanks in advance!
PS:
Unity version 5.5.0f3,
Android version from crush reports 6.0

DeadObjectException with stacktrace pointing to : android.app.ApplicationPackageManager.getPackageInstaller

I'm seeing in crash being reported in crashlytics which has this stack trace which has no mention of my app code.
I have seen DeadObjectException with com.google.android.gms and there, the crash was triggered when removing listeners.
Also, everytime my app starts, I get the installer for logging purposes, i.e.
packageManager.getInstallerPackageName(my-package-name)
There is no callback associated with this call.
Crash is observed mainly on Lollipop and Kitkat, though few Marshmallow and Nougat users have experienced it too.
Has anyone experienced something similar?

Here are the Fabric crashlytics reason for this exception.
DeadObjectExceptions are usually a symptom of a problem occurring somewhere else (likely in a remote process). Even though this exception may be safe to catch, it's worth looking for problems in related services.
This error could mean one of two things:
1) There is a bug (which caused a crash) in an associated process.
2) The other process was killed by the OS.

Android 5.0.1 VerifyError?

I have just updated the OS on my phone to Android 5.0.1. Since this update, an app that I am working on, that is working perfectly fine on my other devices, is now throwing an error in 5.0.1 only. I have no idea what this error means, and it isn't pointing me to a suspicious line of code like it often does.
Has anyone seen this or know what it is about with the new 5.0.1?

For anyone else having any issues since the Android update, I have found and resolved my issue.
The allowed maximum method size has obviously changed. Some of my methods were quite large and complex, and this new limit was obviously exceeded.
This fix was to break larger sections of code into smaller sections.
Hope this helps someone.

MonkeyTalk Causing VerifyException in Android Activity

I'm trying to integrate MonkeyTalk automation into my pre-existing Android app that is built using gradle.
I followed the steps here: Android Studio and MonkeyTalk? and got the demo app working, but when I run it in my own application I get the following crash on the second screen. Any idea why this happens?
This particular stack trace is using L preview targeting SDK 19, but I've also seen a similar (less detailed) stack trace on a Galaxy S4 with SDK 18 on it.

Any idea what this means? I'm using Dagger for dependency injection, is that why it might not work?

You can try the latest version of the monkeytalk and i guess your problem will not occur again.
