Recently, apps that are fine an hour ago now crash when I open them. The crash report message seems to be caused by a null pointer exception (NPE) in com.google.android.trichromelibrary.

Apps affected for me:

  • Gmail
  • Dashlane

Is it just me, or is there actually something wrong with the library? How can I fix these affected apps?

Crash report:

It was a WebView issue and it has been fixed as mentioned here:


Updating Android System WebView and Google Chrome via Google Play should now resolve the issue for all users.

  1. Navigate to Play Store app
  2. Search for Android System WebView (https://play.google.com/store/apps/details?id=com.google.android.webview)
  3. Select the "Update" option
  4. Repeat these steps for Google Chrome (https://play.google.com/store/apps/details?id=com.android.chrome)

For more information about updating Android apps please see: https://support.google.com/googleplay/answer/113412

  • This assumes you can get WebView to update itself. I've tried several times and it just spins and says it's "pending" :( I "uninstalled" it (updates, that it) and all my crashing apps went back to working fine, but it still won't update itself. Maybe tomorrow...

  • @FreeMan you can sideload an update for an app. Download the newest apk (using Raccoon or APKMirror.com) and install it. That's it. If the APK carries the same signature the installed app it would install (confirming that the downloaded apk is indeed genuine and not compromised by a third-party), otherwise, the installation would fail.

  • This answer assume the user has registered an account with Google. It would be better to provide instructions on how to get the APK from public sources.

Downgrading "Android System WebView" (which seems to be related to the Trichrome Library) solved this problem on my phone.
