Fatal Exception: java.lang.NullPointerException Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference

[Hien TT]

Dear Google Mobile Ads SDK Support Team,
 I am consistently encountering a `NullPointerException` within the Google Mobile Ads SDK, specifically when attempting to invoke `getWidth()` on a null Bitmap object. This fatal exception leads to application crashes for some of my users.
It occurs almost SDK version include the latest (24.4.0 or 24.0.0lite)

Hi,

Thank you for contacting the Mobile Ads SDK Support team.

We understand that you're encountering the following NullPointerException related to Bitmap.getWidth() in the Ads Lite 24.0.0 SDK

Although it appears to be intermittent and difficult to reproduce, we'd like to investigate this further. To assist with debugging, could you please provide the following:

• Sample project that reproduces the issue
• Device details and Android versions where this crash occurs most frequently

Additionally, we recommend updating to the latest version of the Mobile Ads Lite SDK — version 24.3.0 — as it includes several stability improvements that may help resolve or mitigate this issue.

I'm seeing the exact same problem for my app since about a month - I am using collapsible banner ads.

I cannot replicate the issue on my devices, but it's happening for a significant share of my users.

I'm also seeing this stack trace, with references to "android.webkit.WebViewClient.shouldOverrideUrlLoading" - maybe this helps tracking down the issue:

I see the same crash, same stack trace and not reproducible locally. I am using collapsible banner ads only.

The crash started to happen around a month ago without changes or app update on my side.

Happens in AdMob SDK version 24.4.0 and Lite SDK 24.0.0 - the Ads Lite SDK 24.3.0 that you suggest to test is not available  (at least on the Maven repository)

[App Hood]

I am also facing it.
