firebase.login error

[Nikoms]

Hello there,

I'm using firebase with the last version of nativescript (2.1.1), and I get an error when I try to login:

JS: Error in firebase.login: Error: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.pm.PackageManager android.content.Context.getPackageManager()' on a null object reference

I just do this on my "init" promise:

firebase.login({ type: firebase.LoginType.ANONYMOUS }).then( function (result) { console.log('ok'); }, function (errorMessage) { console.log('ko'); } );

I don't know if it's related to firebase or this plugin or android?

I'm guessing you're doing login before application.start(). Is that right?

[Nikoms]

Indeed, sorry for the inconvenience :)

[EddyVerbruggen]

No worries. I'll try and harden the plugin so it can cope with that setup better.

[EddyVerbruggen]

Just pushed a change to this repo (not on npm yet) where you should be able to call login before application.start()

[Nikoms]

Amazing Eddy! Thank you

Just in case someone else encounters the same error message when using nativescript-plugin-firebase.
If you change the android:name="com.tns.NativeScriptApplication" inside the AndroidManifest.xml when enabling multidex for pre lollipop devices this error happens.

https://docs.nativescript.org/runtimes/android/advanced-topics/extend-application-activity
Instead of using the android:name=org.myApp.Application from the example in the link above. Use com.tns.NativeScriptApplication inside of application.android.ts.

angular nativescript
In build.Gradle
deleted multiDexEnabled true
and it fixes it
