Question: i have been struggling with it for hours and I would like to ask you for the help, what VBA code and how should I implement this as I have around 30 tabs and I would like to create kind of a drop list in order to simplify switching between the tabs.

Answer: 
In your `AndroidManifest.xml`, do you have `android.intent.category.LAUNCHER` in the `intent-filter` for your main Activity?

This should be inside the `<activity>` tags of your main Activity:

```
<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

```

Without this tag, the launcher won't list your application.

EDIT: After seeing your manifest, you've combined your launcher and deep link `intent-filter` into one which will not work. You should keep them separate:

```
<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data
        android:host="t4jsample"
        android:scheme="oauth" />
</intent-filter>

```
Go to `/{PROJECT_NAME}/app/build/outputs/apk` and you can manually install it onto the device. Although in my experience the app has always installed onto the device when I run it.
