ERROR: Cannot initialize Map with error UNKNOWN - here-api

Question

Whenever I try to initialize the map, I always get the "error UNKNOWN" message.
I tried the examples from HERE, but I get the same error on all of them. So I made a very simple and clean application with the sole purpose of loading the map. It still doesn't work and I can't put my finger on it.
I'm using Android, trying to target version 4.4 (KitKat).
I am using the Premium SDK (during the 90 day trial).
I verified the app key, code and licence key many times now. They are absolutely correct.
The registered package name is
com.example.workywork
but in the manifest I have:
package="com.example.workywork.testherepremium"
(It was supposed to be a test, so don't mind the package name :) )
I think it is right, since they asked for package name, not for package name + project name.
Here is the code from my simple application:
Build.Gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
defaultConfig {
applicationId "com.example.workywork.testherepremium"
minSdkVersion 19
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'

I also tried to use
android:process="global.Here.Map.Service.v2"
with
android:name="com.here.android.mpa.service.MapService"
or
android:name="com.here.android.mpa.service.MapService.v2"
Or any other such combination.
What am I missing?
As you can see, I've been struggleing with this for a couple of days now ;)
Thank you very much for your help. It is greatly appreciated.

The applicationId has to match the registered name exactly (in your case com.example.workywork). Otherwise, I can't spot an issue with the code you've posted.
You can try following this guide: Creating a Simple Application Using the HERE SDK
