ConnectivityChangeBroadcastReceiver thrown on 2.3.0-beta*

[SimonSimCity]

I've recently tried out the version 2.3.0 beta-7, you published, and got the following exception:

Java.Lang.ClassNotFoundException: Didn't find class "md546bf78c6c1ea5df684f3f928d8d05883.ConnectivityChangeBroadcastReceiver" on path: DexPathList[[zip file "/data/app/com.storeflix.droid-1/base.apk"],nativeLibraryDirectories=[/data/app/com.storeflix.droid-1/lib/arm64, /system/fake-libs64, /data/app/com.storeflix.droid-1/base.apk!/lib/arm64-v8a, /system/lib64, /vendor/lib64]]

I haven't tested it thorroghly, but found this issue in the Xamarin forum, that looks like the same error: https://forums.xamarin.com/discussion/79841/connectivity-plugin-noclassdef-exception-with-latest-android-version-nougat

Went back to 2.2.12 and it works again.
Tested on Samsung SM-T280 (API 22)

I am unable to reproduce this on new builds at all on both Cycle 7 and Cycle 8 targeting against API 23 or API 24. You can try 2.3.0.34-beta which is the latest.

This is also happening an a Dell Venue 8 - 7840 - which has Android API 22. Reverted to 2.2.12 and it works again. Maybe this helps.

It happened on a Lenovo Tab 2A7-20F.
What are the consequences of commenting the MainApplication file?
I just commented this: //[Application] and the app runs again.

Wow I suddenly started to get this exception with 3.0.3. I am on the latest build tools (26.0.2, 26.1.1 SDK tools). The target is level 26. Visual Studio on Mac.
I tried the latest beta and also the 2.2.12 but nothing works.

Always getting the class not found exception and this in the output:
[Mono] Assembly Loader probing location: '/storage/emulated/0/Android/data/ch.elopsis.grat_ici/files/.override/Plugin.Connectivity.dll'.

Looks like you are AOTing it... haven't test that out. Would report in bugzilla.

[Greg767]

Thanks for your input on this James, although I don't understand it. What do you mean by "you are AOTing it"? Is there a compiler setting somewhere for it? I haven't set anything on purpose to AOT it. I have to use ProGuard and MultiDex in my project otherwise it doesn't compile at all (error code 1 or 2).
I was looking at multidex setup with the .keep file because I was thinking that it doesn't find it because of that.

[Greg767]

So the exception (not the output) contains this: Didn't find class "md5a7903531ac28e2eb4c8576cdf2655bda.ConnectivityChangeBroadcastReceiver" on path: DexPathList[[zip file "/data/app/ch.elopsis.grat_ici-1/base.apk"],nativeLibraryDirectories=[/data/app/ch.elopsis.grat_ici-1/lib/arm64, /data/app/ch.elopsis.grat_ici-1/base.apk!/lib/arm64-v8a, /system/lib64, /vendor/lib64]]
And looking at the classes2.dex file I find the ConnectivityChangeBroadcastReceiver but the package is this: md55acd92097db1193d6a1e7330cb14252a which is not the same as in the excpetion. I don't really understand how it is possible.

[Greg767]

James, FYI I have a VS2017 Mac Community edition, so I cannot handle the AOT by gui and setting it to false in the csproj file has no effect on anything. Output is the same and the error is the same.
Any ideas where to look?

[Greg767]

Bahhh I found the problem. There is a bug in the latest stable Forms release....
https://bugzilla.xamarin.com/show_bug.cgi?id=60337

I just stepped one release back on Android....

[ruisilva450]

On Xamarin.Forms 2.5.0.121934 and Xam.Plugin.Connectivity 3.0.3
The OS is Android 7.0

[kensam94]

I solve the problem by adding Access Network State and Internet Permission.
