  );

Expected Behavior

Startup without Errors filling the logs

Actual Behavior

Starts up, appears to work but there's lots of errors in the logs related to com.engage.BuildConfig not being present. I don't remember seeing that beforehand.

Steps to Reproduce

1. Startup app.

Context

General Geo Fence and breadcrumb tracking.

Debug logs

This is not a crash. The plugin is catching this exception and rendering the stacktrace you see here. However, there seems to be a problem in your android config.

Show me the following files:

• android/app/build.gradle
• the <manifest> element from your AndroidManifest, eg:

  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  package="com.transistorsoft.flutterbackgroundgeolocationexample">

[christocracy]

There it is.

• in build.gradle:

  applicationId "com.engage"

• But in AndroidManifest

  package="com.engagemobilize.engageapp"

They're supposed to be the same.

Btw, you don't want to be releasing with debuggable true. That would be a big security hole in your app.

buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            debuggable true
