Admob ads not showing, not even test ads

I don't get what I'm doing wrong, I wanted to show a banner on the bottom but not even the test ads show up. I followed their tutorial and my app looks like this:

xml with the ad (it does show up on the preview)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/infoPageBackgroundColor"
android:orientation="vertical"
android:paddingTop="8dp"
tools:context=".AppInfoActivity">

...

<com.google.android.gms.ads.AdView
    android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    app:adSize="SMART_BANNER"
    app:adUnitId="@string/banner_id"/>

Metadata in AndroidManifest

<meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="@string/app_id"/>

Project gradle.build

buildscript {

repositories {
    google()
    jcenter()
    maven {
        url "https://maven.google.com"
    }

}
dependencies {
    ...
}
}

App gradle.build

dependencies {
...
}

Entry Activity

import com.google.android.gms.ads.MobileAds;


public class EntryActivity extends BaseActivity {
private View progressBar;
private LoadListAsyncTask loadListAsyncTask;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    ...

    MobileAds.initialize(this, "@string/app_id");
}

Java file

...

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;

...


public class StickerPackListActivity extends BaseActivity {
...

private AdView mAdView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...

    mAdView = findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);
}
...

I'm using the banner test ID to try it and it only shows up in the xml editor. Any idea of why? Even if I try my ID it deosn't work. Sorry for not being able to explain much more as it's just like this. Did I forget something?

You forgot to initialise AdMob:

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    MobileAds.initialize(this, "BANNER_ID_HERE");
    mAdView = findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);
    ...
}

https://developers.google.com/admob/android/banner

Recently created AdMob banners sometime fail to load with error code 2 when tested on physical devices. You should always test them on an emulator to ensure everything has been done correctly, seeing as there is nothing wrong with your code.

You need to initialize the Ads SDK:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // ...
    // Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713
    MobileAds.initialize(this, "YOUR_ADMOB_APP_ID");
}

Also make sure that your app id and banner id are correct:
