NullPointer exception on beginChat

[omaroskars]

Followed the installation for Android. When i try to start the chat I get a nullpointer exception.

<activity android:name="com.livechatinc.inappchat.ChatWindowActivity" android:configChanges="orientation|screenSize" /> Is in the manifest

Have you added:
<activity android:name="com.livechatinc.inappchat.ChatWindowActivity" android:configChanges="orientation|screenSize" />

in your android manifest?

[omaroskars]

@Mastersam07 Yes, The activity is in the manifest.

[omaroskars]

When I open the app in Intelli J, The manifest doesn't recognize ChatWindow activity for some reason. Do I need to install LiveChat in android Gradle?

[Mastersam07]

Can I have a minimum reproducible project?

[Mastersam07]

Where exactly in your manifest are you adding this?

<activity android:name="com.livechatinc.inappchat.ChatWindowActivity" android:configChanges="orientation|screenSize" />

[Mastersam07]

@omaroskars can you check the manifest in the example and confirm with what you have?

[omaroskars]

The thing is it works on a minimum reproducible project, but when i add it to my enterprise app it seems the activity doesn't get initalized for some reason. This has probably something to do with my project but i was hoping you could help me figure it out.

What plugin version are you using?

[Mastersam07]

Can I also get a reproducible project?

[Mastersam07]

I just tried replicating with livechat version livechat: ^1.0.0+1 and I didn't encounter issues.

[omaroskars]

I think your plugin works as expected. The problem is probably with cached dependencies in my project, because I implemented the live chat plugin natively to begin with. I changed my native code to run "intent" like in this plugin does and everything works as expected.

Thanks a lot for your help
