java.lang.RuntimeException: Internal error in Firest         


        

Answer 1

I had this same issue and none of the solutions worked for me when I tried them individually. After trying out various combinations that were already posted and trying out downgrading and upgrading dependencies, finally the solution below worked for me:

First, ensure you have these versions in your project level build.gradle file:

classpath 'com.android.tools.build:gradle:3.3.2'
classpath 'com.google.gms:google-services:4.2.0'

Secondly, ensure you have these versions in your app level build.gradle file:

implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-auth:16.2.1'
implementation 'com.google.firebase:firebase-firestore:17.0.1'

After this, if you have build and/or sync issues, replace

implementation 'com.google.firebase:firebase-firestore:17.0.1'

with the below code having the exclusions that prevents your build to finish successfully: (in my case these 3 exclusions were needed)

implementation('com.google.firebase:firebase-firestore:17.0.1') {
    exclude group: 'com.squareup.okio'
    exclude group: 'com.google.guava'
    exclude group: 'com.google.code.gson'
}

Also, ensure you have this at the end of your app level build.gradle file:

apply plugin: 'com.google.gms.google-services'

Furthermore, you need to have this in your proguard-rules.pro file:

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

Only after applying all these did my app work properly! I hope that it will help someone...

Answer 2

To solve this, please add the following line of code in your build.gradle file:

implementation 'com.google.firebase:firebase-core:16.0.1'

According to the official documentation:

Your app gradle file now has to explicitly list com.google.firebase:firebase-core as a dependency for Firebase services to work as expected.

Don't also forget to add in your top level build.gradle file the latest version of Google Play Services:

classpath 'com.google.gms:google-services:4.0.1'

Please see here more informations.

Answer 3

From firebase support reply I solved this issue by adding below to progauard rule in future if someone facing this issue try this solution:

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}
