Hi! After using the app for a few days, I found just one problem. Sometimes, when I select a comic from the library to open, the app just close itself. No error is displayed. If I open it again, the comic just open like normal.
Is there anything I can do to help track down and kill this (I believe) little bug?
For reference, I´m using a Google Pixel C, stock, no modifications (yet ;) ) and the comics with this error are plain cbz files, created without any compression using Winrar.

Edit: Looks like the test version from your post #300 don't suffer from this issue. I will test it a little more, but since I installed it, I have not seen the problem even once. Thanks in advance!

Did you notice some repro steps (like for instance: the problem occurs only when you exit the app from library, and then restart the app) ?
How often the problem occurs ? Everytime, or only sometime ?
What kind of options did you set ? For instance, did you set the "Autoload" option (to open automatically Library on start-up).
What is your device and Android version ?

Thanks for your help.

Hi!
I noticed it happened every time I opened one comic from a folder with more than about 40 comics.
But since I started using the test version from your post #300, it didn´t happened again. I can say it´s fixed for me in this version.
If it helps, I have it configurated to open in the library and don´t display the home screen.
My device is one Google Pixel C, using the latest Marshmallow, stock, no modifications.
And one more thing! There are a few errors in translation to my language (Brazilian portuguese). Is there a way for me to correct the translation for you?

And again, thanks a lot!

Thanks! I already fixed the word Library in all entries I could find (the correct translation is "Biblioteca" and it was "Livraria") :victory:
I will keep translating when I have some time!

Hi, The Challenger!

I found another little bug:
Some of my files have names with symbols not present in English, like the letter "ó". For example, I have one Justice League (cbz file) and inside it, I have files named "JL1 cópia 1.jpg" JL1 cópia2.jpg" etc.
And in my tests, every cbz or cbr I have with files with names like this, the app can´t show anything. When I open the comic, it just show one black screen and nothing else.
Can you please take a look at this? I know I can just uncompress and rename my files, but I really have hundreds of them, and the ammount of work to fix it by my side would be insane. :eek:

Thanks a lot in advance, once more!

EDIT: Since I already used the app for many hours and this bug just started now, I went to investigate a little more, and in my tests I can say it only happens in Android 7.0 (Nougat). My files with the same name structure were working fine in 6.0 Marshamallow. Don´t know if this can help to find the problem.

EDIT 2: I found now it only happens with CBZ files. CBR ones work fine, no matter the names of the files inside.

Hi Warell,

Thanks for your feedback.
I will try to reproduce the problem on my side. I will use an Emulator because I don't have any Android 7 devices.
I will keep you updated once I reproduced it.

Thanks for your help.

Thank you for your time!
For now, I just recompressed the series I'm reading into CBR and everything is working fine. Was really much easier than rename all pages (even if I used an app to mass rename, would consume an immense time).
I'm using one Google Pixel C. Don't know if it can generate any logs to help you find the cause of the problem.
Let me know if there is anything I can do here to help.
And thanks again for the great app!

I reproduced the problem using an emulator (with latest Android 7 Rom).
I identified the problem. Now I have to fix it.
Once fixed, are you OK to validate the fix ? (using a test version).

Thanks for your help.

That's right. But it's related to the Android version.
Android 5.1 (and beyond) supports vectorial icons, it means icons (if converted in vectorial icons) can looks crisp on all screen and all resolutions.
On older versions (Android 5.0 and below), the app is using simple image icons and it can be displayed blurry on large screens ...

So, on CM 12.1 (based on Android 5.1), the app will use vectorial icons.
And on your miui 8 (Android 5.0.2), the app will use simple image icons.

I don't know if it's possible to upgrade Android version on your miui 8. It will fix the problem but I don't know if you want to upgrade your device only for this problem ...
