FirebaseInitProvider crash when trying to run app

Question

I implemented the new FCM on the app following the steps on the FCM web.

Now, I'm trying to run the app, but when I try it, the app crash with this error:

As I can see, thre method is trying to get some value, where is null.

I searched for solutions, and found this post in SO. --> Unable to get provider com.google.firebase.provider.FirebaseInitProvider

As solution they said to add the applicationId to the gradle build project file, but I got it:

defaultConfig {
        applicationId "es.in2.otr.app.im"
        minSdkVersion 16
        targetSdkVersion 23
        multiDexEnabled true

        testApplicationId "es.in2.otr.app.im.test"
        testInstrumentationRunner "android.test.InstrumentationTestRunner"
    }

And stills crashing.

Is there some workaorund or solution to this problem?

Answer 1

Add the line compile 'com.android.support:multidex:1.0.1' to your dependencies (or simply remove multiDexEnabled true if not required)

Add this attribute to the application tag in manifest:

android:name="android.support.multidex.MultiDexApplication" 

If you already have a custom application class defined in Android Manifest, extend it from MultiDexApplication instead of Application

This works for me!

Answer 2

I had the same problem. After adding the aplicationId i noticed that there were 2 apps installed on my device. I think it somehow changed the package name of the app leading the device to understand that were two different apps.

So i uninstalled the two versions and then it worked.

ps: The command line is not launching the app normally. It says: "Launching application...LAUNCH SUCCESS" but the app is never launched, i have to open it manually

EDIT: Just found out that i was type a wrong application id, now it works properly
