A number of Android apps started to crash, including Gmal, for me on my Android phone last evening and this morning. Tried the normal reboot, update apps and system update. Those did not help.
While searching for information if there is a known issue I found this:
Android apps like Gmail are crashing and ‘WebView’ is to blame article tells “A number of Android users (self included) suddenly saw notifications pop up on their devices saying that apps had stopped running. Many of the apps throwing errors suddenly can’t be opened, and they include important ones like Gmail, a number of banking apps, Google Pay and others.”
The recommended first solution was
Uninstalling one Android app could get your phone working normally again.
I did not try that immediately because it seems that Google has confirmed the issue and its link to the WebView app. According to a spokesperson, “We are aware of an issue with WebView causing some apps on Android to crash. We are currently working to fully validate the scope and a fix is in progress.” According to the status message, there will be an update.
I checkedv Android system WebView info at https://play.google.com/store/apps/details?id=com.google.android.webview. There was a new update available. Installing it solved the problem for me with Samsung A70.
