Issue with ClassNotFoundException for local notifications plug-in

kathode · Nov 14, 2016

Hi,

I'm having a terrible time getting a local notifications plug-in to work. I keep hitting a ClassNotFoundException no matter what I do. I have a setup with a number of different plug-ins so my manifest is a little complicated. I imagine the issue is there, but I'm not skilled enough with Android to figure it out.

Here's my main manifest:

<?xml version="1.0" encoding="UTF-8"?>

And here's the manifest as it stands with the plug-in:

<?xml version="1.0" encoding="utf-8"?>

And the error I'm getting in logcat upon initializing the plug-in:

To avoid overwriting my main AndroidManifest.xml, I put the plug-in in its own folder: /Plugins/Android/Notifications. In that directory is the plug-in manifest, the plug-in jar file, and a res/drawable directory for notification icons. I've expanded the jar and verified that the NotificationActivity.class file is contained within.

Can anyone see where the issue might be?

The manifest only declares components and other pieces of data to the Android OS, so it seems unrelated to your issue of a ClassNotFoundException.

I would check whether that class is included in the final APK as the first step.

Both androidManifest.xml should have the same minsdk and targetsdk value. It resolve lots of issue for me. But I agree with liortal.
