Expected behavior App launches without the NullPointerException

Did this ever used to work Similar error happened with google tabs client.

Screenshots

Code Snippets Splash screen strategy is being set with this code:

this.mSplashScreenStrategy = new PwaWrapperSplashScreenStrategy(this, this.mMetadata.splashImageDrawableId, this.getColorCompat(this.mMetadata.splashScreenBackgroundColorId), this.getSplashImageScaleType(), this.getSplashImageTransformationMatrix(), this.mMetadata.splashScreenFadeOutDurationMillis, this.mMetadata.fileProviderAuthority);

These all have values except for transformation matrix which is null.

We have released 1.4.0-alpha01 yesterday with the fix for this issue included:

    implementation 'com.google.androidbrowserhelper:androidbrowserhelper:1.4.0-alpha01'

androidx.browser-1.3.0 has finally hit stable and we have released version 2.1.0 of android-browser-helper, which depends on the new androidx.browser version. This bug shouldn’t happen anymore when using that. To use it, update the app’s build.gradle as below:

implementation 'com.google.androidbrowserhelper:androidbrowserhelper:2.1.0'

Thanks for the patience for this issue to be resolved.
