Fga: Service stops on friend support select screen when custom supports are preferred.

Created on 27 Jul 2020 · 12Comments · Source: Fate-Grand-Automata/FGA

I have been running FGA on my Bluestacks for a week or three now without issues. However, I recently downloaded the latest release (I updated from 1.15.0) and ran into a bug. Whenever I have a skill setup with one or more custom preferred servants or CEs set, the service will stop itself on the support select screen. Everything else works fine, even the custom image maker, or the support select screen when my preferred servant or CE is one of the built-in ones (as demonstrated in the video below). All of the fine tune settings are at their defaults (I even set the swipes and updates to their default values just in case).

If I try to enable the service again after the second crash, it tells me to enable accessibility (also demonstrated). Turning it off and on again fixes that.

I made a video to demonstrate the bug: https://streamable.com/habsqe
The custom support image was a new one I generated specifically for the test.

(After having typed this up I tried a full reinstall of the app, just in case. Didn't help)

Edited to change 'Friend select' to 'support select'.

Do a few things, please:

Install https://androidmtk.com/download-minimal-adb-and-fastboot-tool
Follow this guide https://stackoverflow.com/a/55804751/5971497
After adb connect, run adb logcat *:E > C:\logcat.log
Look at the log entries around the time the app crashes and see if you can find anything about an exception being thrown

The best I can find is an error:

Followed by this exception

No pending exception expected: java.lang.ClassNotFoundException: Didn't find class "org.opencv.core.CvException" on path: DexPathList[[zip file "/data/app/com.mathewsachin.fategrandautomata-2/base.apk"],nativeLibraryDirectories=[/data/app/com.mathewsachin.fategrandautomata-2/lib/arm, /data/app/com.mathewsachin.fategrandautomata-2/base.apk!/lib/armeabi-v7a, /system/lib, /vendor/lib, /data/downloads, /data/priv-downloads]]

The same exception is thrown again later just before it seems the whole process gets terminated.

I'll include the log itself as well, since I'm not sure what exactly I'm looking for.

@MathewSachin is this maybe related to the cvtColor method here? https://github.com/MathewSachin/Fate-Grand-Automata/commit/a704a511bab68b74eab08258ed4632fc6ba5b621#diff-9d6bcbd675a451c34373f6eb042c8f98R34

My guess is that matching greyscale templates doesn't work anymore.

I understood the problem from the logs. Just saw this in the middle of the night. I'll push a fix when I wake up tomorrow.

The problem should have appeared with the Story Skip fix where I kind of assumed that the loaded image will be RGBA, while images made by support image maker are gray-scale. And since I didn't use custom support images this event, I didn't notice this.
