android – Register Application class in Manifest?

Posted by: admin March 10, 2020 Leave a comment

Questions:

I have one Application class to keep the global state of my application. But I’m unable to register it in Manifest file? Any idea how to do this?

How to&Answers:

If it derives from Application, add the fully qualified (namespace + class name) as the android:name parameter of the application element in your manifest.

<application
        android:name="com.you.yourapp.ApplicationEx"

Or if the class’ package can be described as relative to the package in the manifest tag, then just start with a .:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.you.yourapp">

    <application
        android:name=".ApplicationEx"

Answer:

but in case you are already using some library like branch.io’s library then most probably your manifest

<application name="">

property will already have some name like

`<application name="io.referral.BranchApp">

in that case you need to first extend your application class, like below:

public class Application extends BranchApp

and then register your application in manifest as:

android:name="absdevelopers.com.brankreferal.Application"

this works perfectly for me 🙂
i hope it helps someone in trouble 🙂

Answer:

If you are using a MultiDex application you will already have “android:name” in use so instead extend android.support.multidex.MultiDexApplication:

public class MyApplication extends MultiDexApplication {...}

And add it to the Android manifest:

android:name="app.package.MyApplication"
