Class 'MyApplication' is never used

Question

After I successfully integrated flurry SDK into the library by using this code in my build.gradle file.

    compile 'com.flurry.android:analytics:6.8.0'

I created java Class to integrate my API Key into my code, and since Im running my app on an external device I suppose some data needs to show on my flurry account, but it is now four days and nothing changed, only zeros are showing on my dashboard ...

Also, i have this message on my java file

Class 'MyApplication' is never used

Ps: I'm new to android studio

Certainly the documentation that you should be reading mentions what to do with that class...? – Kahlil

it not very clear, they included the code with i pasted but nothing else – Jammiejammin

Answer 1

You must specify MyApplication in manifest file. It will not be used otherwise:

<application
    android:name=".MyApplication"
    ....

i typed it like that <application <activity android:name=".MyApplication" ></activity> there is no error in MyApplication.java, but in manifest i got >My Application is not assignable to 'android.app.Activity' Validates ressource referances inside android XML file the code is working fine on my device no crashing at all, but will that error affect my code after ? – Jammiejammin

@Marcin it is not a valid answer. After adding into Manifest, it still says that this class is never used. – Rota

The warning still appears in Android Studio Arctic Fox 2020.3.1.1. Not even using the full class name of the custom Application class fixes it. – Learned

Answer 2

It's a class, not an activity. So you should write it as :

<application
    android:name=".MyApplication" //you should write like this
    android:allowBackup="true"
</application>
