Endless loop when clicking on "Cancel" with certain activity themes

[rfc2822]

Hello,

I'm trying to use MemorizingTrustManager with HttpsUrlConnection (setSSLSocketFactory, setHostnameVerifier). It's a quite simple setup so I don't think I've done anything wrong; it' works quite well, but there is one problem:

When clicking on "Cancel" (= the certificate shall not be used), the HttpsUrlConnection (I think it's the getInputStream() method) takes forever and according to adb, there's an endless loop + a memory leak, too.

Have you ever heard of such issues with HttpsUrlConnection and "Cancel", or do you know a working example of HttpsUrlConnection + MTM?

Thanks for your work.

Hi, the default example in the repository's example directory is using HttpsURLConnection, and there are no known issues with the "Cancel" button. I just verified that on Android6. Can you provide more information or maybe a stack trace?

[rfc2822]

Thanks for testing this. The problem is that it doesn't crash… I'll try to find out how to get a stack trace or maybe profiling information to see what's actually going on.

[rfc2822]

Funny, it's related to the android:theme of MemorizingActivity. With android:theme="@android:style/Theme.Translucent.NoTitleBar", it works as expected, but with android:theme="@style/Theme.AppCompat.Light.NoActionBar" (which I have used before; it's a support library theme) there's an UI endless loop (maybe only on Samsung, as I have seen com.samsung.* classes in the profiling results).

Do you have any hints which themes are acceptable / how the support library's Material theme can be used?

[rfc2822]

From various tested themes, only @android:style/Theme.Translucent.NoTitleBar and @style/Theme.AppCompat.Light.Dialog seem to work, while the endless loop occurs for all others… very strange, but I guess this is not related to MTM.

Maybe it would be good to mention which themes are usable (and even better, why) in the documentation.

To be honest, I wasn't even aware that this is a problem, and I have no idea what the cause is.

I had the hope to bring #29 into a shape that would allow completely removing the MTM activity, but there was no progress in a looong time. I will keep this issue open for now, for documentation reasons, and make a statement in the README someday ;-)
