Somewhat related question: at what point do you plan to stop supporting Android versions older than 5.x?

[ByteHamster]

As soon as ExoPlayer or another similar key library no longer supports 5.x

[schwedenmut]

I wanted to get a look into this, but AntennaPod 2.0.0 didn't even bother to start on a 4.4 emulator.
Ran straight into a ClassNotFoundException ^^. Any thoughts/hints?

[ByteHamster]

Make the class PodcastApp extend MultiDexApplication. The crash only happens on old devices and only in the debug version. Details (and reasons why this is not already changed) here: #2813

[ByteHamster]

I guess this one is pretty hard to fix because it requires to understand how stack blur works. An alternative would be to just display the image without blur as a fallback.

[schwedenmut]

I did quite some debugging during the weekend and ran into other issues while downloading the images (SSL Errors).

As a first improvement, I will go ahead and display the unblurred image (fallback). But still would love to find out why the array gehts out of bounds 🤔.

[ByteHamster]

ran into other issues while downloading the images (SSL Errors).

Do you use the "play" or the "free" build variant? Do you have Google Play services installed? I hope that this is a certificate problem, not a protocol problem.

[schwedenmut]

Oh bugger, I used the 4.4 AVD without Google (╯ರ ~ ರ）╯︵ ┻━┻
will test that again with the Google AVD ....

[ByteHamster]

AntennaPod should also work without Google. This is probably caused by #4328. I think I fixed that in #4497 but that PR needs careful review.

[schwedenmut]

Currently I am using both variants next to each other. On the freeDebug with non Google AVD sometimes I get an SSL handshake aborted stacktrace while on the same Podcast on playDebug with Google AVD there is no issue.

But this could be another Issue resulting in grayed background images but not linked to the stack blur algorithm/functionality.
