`IidCompatibilityCheckFailure` lint check fails with a null pointer exception (NPE)...

IidCompatibilityCheckFailure lint check fails with a null pointer exception (NPE)...

Using bom 25.4.1 and Iid 20.2.0

The check failed to run as it encountered unknown failure. This is most likely caused by a new version of Android Gradle Plugin that this check does not support. Please make sure your build does not depend on firebase-iid version earlier than 20.1.1 as it will cause issues.

[REQUIRED] Step 2: Describe your environment

• Android gradle plugin 4.0.0
• Firebase Component: bom 25.4.1 and Iid 20.2.0

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

Run lintRelease

Seems to be related to dagger 2.28, or Google places SDK 2.3.0 or androidtimesquare lib 1.7.10

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

I used the following setup you mentioned but I couldn't reproduce this issue:

• Android gradle plugin 4.0.0
• Firebase Component: bom 25.4.1 and Iid 20.2.0
• Gradle version: 6.1.1

It's possible that the firebase-installations lint check could fail to run on a newer version of Android Gradle Plugin. But I tested it out with Android gradle plugin 4.0.0 and the check works as expected.

Could help me with more details like

• Your app android dependency graph? This will help us identify if you are running any incompatible iid version
• Any other steps that can help me reproduce this issue.

I am using Gradle 6.5

Hi Thanks for the Gradle version. I tried running with that version and still dint see the check fail. Are you able to consistently run into lint check failure.

[yogurtearl]

Yes, it is a nullpointerexception, but not sure how to get lint to print the full stack trace.

I started to get the same issue in Android Studio when performing a code inspection.

Gradle: 6.1.1

Firebase dependencies:
implementation 'com.google.firebase:firebase-analytics:17.4.4'
implementation 'com.google.firebase:firebase-ml-vision:24.0.3'
implementation 'com.google.firebase:firebase-ml-vision-face-model:20.0.1'

Thanks for your response @perracolabs &

I will try with versions as shown in @perracolabs comment & see if I am able to reproduce the issue.

@perracolabs Which version of Android studio & Android Gradle plugin are using?

[ankitaj224]

When you run lintRelease it generates a local HTML report with detailed errors. You can try checking if that file has the full stack trace.
