Create libraries to manage your comics collection

Opening files one by one can be quite annoying. If you have a lot of comics files, the best way to manage them is to create a library.

A library is a collection of comics files displayed with covers and grouped by collection, for instance all Batman issues are grouped under Batman collection. Once created, you can easily browse and switch to next issue of a collection.

Before creating a collection, check that your files are correctly dispatched in folders (if it does not match, don’t worry, you can choose “Folder” display mode in Options => Library => Library Display Mode). Here is a sample of folder hierarchy :

  • Library
    • Batman
      • Issue 1.cbz
      • Issue 2.cbz
      • Issue 3.cbz
    • Spiderman
      • 01.cbr
      • 02.rar
      • 03.zip
    • Hulk
      • 01
        • 0001.jpg
        • 0002.jpg
        • 0003.jpg
      • 02
        • 001.png
        • 002.png
        • 00.3.png

To create a library, you must choose the “Library” option item. If there is no existing library, you can choose “Add” action and then browse to the Library folder (only folder can be choose to create a library). Once folder selected, application will scan folders to retrieve comics informations and then display the library.

  1. Deleting history doesn’t delete the last page read for all items. If you want to re-read your comics, it opens in the last page, which is a pain. deleting cache unfortunately deletes even your custom settings. Please consider some solution. Thanks

    • There is an option to specify How comics should be opened from library
      (in Options => Library => Load Comics from library view).
      You can choose if you want to open comics from the beginning or to open
      it at the last read page.

  2. Hi, Can this viewer add one feature “split image”, like other viewer (ex. scviewer, pv)does. because comics are usually scanned 2 pages in one image, thanks!Challenger viewer’s Vertical/Horizontal scrolling is really great for mobile device.

  3. Hi ! I’ve just downloaded your fantastic application. I’m just wondering if the is a way to add a bookmark on a page ? I don’t find it on the available options where you are reading.

    Thank you for your help.

  4. Bonjour,
    Serait-il possible d’ajouter une option d’affichage du numéro de la page en cours par rapport au total des pages (ex:12/56)? Merci d’avance

  5. I’m using this application on the nook color. Is there any way to get out of full screen mode when everything except the home key is virtual?

  6. I have a main folder for comics and about 100 subfolders each containing jpg images. Each folder has a first jpg file that I use as it’s library image. I want to display a library image for the parent directory but instead Challenger displays the first jpg image in the first sub folder as the image for the parent folder. How can I get it to display an image from the parent folder as the parent folder image?

    This is excellent software for displaying scanned jpg images of my newspaper comic strips. Thanks.

  7. My HP Slate 21 does not have a position sensor. I want to read my comics using full screen in Portrait-mode, but none of the viewer apps I have tried allow for this. Can you please add a control to manually set the display mode to full-size portrait display so I can finally enjoy my comics.
    Thanks in advance,
    Chris

    • There is already an option to force portrait display or landscape display.
      The option is in “System” option menu, named “Lock orientation auto switch”.
      You can choose to force portrait or landscape.

      • Merci pour ta response rapide, mais cette option ne change pas la facon d’afficher l’image, je me retrouve toujours avec une image recouvrant environ un tiers de l’ecran, alors que je cherche a avoir une image avec rotation 90 degres qui est affichee sur la quasi-totalite de l’ecran.

      • Je ne suis pas sûr d’avoir compris le problème …
        Si tu veux changer le mode d’affichage (pleine largeur, pleine hauteur ou plein écran), il faut utiliser l’option “Type de remplissage” dans le menu “Affichage”.
        Si cela ne convient pas, pourrais tu me donner plus de détails pour que je me représente plus clairement le problème.

      • Voici l’illustration exacte de mon probleme par une autre personne sur le forum.xda-developers.com/showthread.php?t=2525204 . L’image parle mieux que moi… Avec PERFECT VIEWER je peux effectuer une rotation manuelle image par image, mais ce n’est tres comfortable. En plus, je cherche encore une solution pour avoir du full screen sans les SOFTKEYS qu’on voit aussi sur l’image. Bon weekend, Chris

  8. Belle application cependant je n’arrive pas à accéder à mon catalogue opds situé sur mon nas. Sous quelle forme dois je rentrer l’adresse ? Pour information avec moon reader j’y accède sans problèmes. Merci d’avance

  9. Merci pour la rapidité de la réponse. Mon catalogue opds est accessible via un fichier feed photo que ne visais pas en tapant l’adresse du coup l’app ne le trouvait pas. Maintenant tout est OK.

  10. Great program! Easily surpasses all the others I’ve tried. I’ve been trying to read comics on my android tv and I’m wondering if it’s possible to do ‘auto-scroll’ – where you start a comic and the page scrolls by without user intervention? My tv doesn’t have a touch screen, so I have to use a keyboard mouse – this feature would make reading on a big screen so much more enjoyable.

    • I never tried to run the app on android TV. Does it work correctly ?
      I think it should be possible to find a way to trigger auto-scroll.
      I will do some tests on my side using android TV emulator and I will keep you updated.

  11. (Should have been more clear) An option button to start autoscroll would probably work better… long pressing the screen doesn’t seem to work for me. Thanks again.

  12. Is it possible to read from manga hosting websites with this app? And it is possible to add the option of using volume button to go to next/previous page?

    • There is already an option to go to previous/next pages using volume button. You can activate it using options (in Options => System => Volume button action).
      About manga websites, It’s not possible to read comics hosted on manga websites, sorry.

  13. I am using this software as it’s the one I’ve found to work with cloud storing services, so that I can have my cbr stored there and not filling space in the tablet. So far so good 🙂

    Now I’ve a question regarding the Library and the collection grouping options.

    I’ve added a webdav folder to the library.
    /dav/Folder

    Thing is that, Folder has some cbrs there, and also a Subfolder, with more cbrs.

    No matter if I choose “No collection grouping” or “Grouped and don’t use sub-folders name as comics prefix” the library, displayed as grid, shows two folders: “Folder” and “Subfolder” each one with their respective cbrs.

    Is there any way to have the library just show “Folder” and, upon clicking on it, see the cbrs contained in “Folder” and the ones in “Subfolder” there as well?
    I really don’t understand why the grouping option made no difference whatsoever.

    Keep up the hard work.

      • Thanks for the reply, but this hasn’t worked as I expected.

        If I choose “Folder”, that’s what I see in the Library section:

        All the cbrs contained in “Folder” directory right away + one folder with “Subfolder” name in it.
        If I click in “Subfolder” then I can navigate to its contents.

        If I add yet anoder webdav folder to the library (say Folder2) then what I get in the library view, with “folder” display mode is:

        Folder+Folder2 comics mixed there right away + Subfolder.

        I wouldn’t want comics from different folders to be mixed.
        It hasn’t made a change if I chose “No grouping” or “grouping”.

        I’m back to Grid view for the time being, it’s still the one that is closer to what I expect.

  14. Generating a library from a cloud drive takes quite a while, even on WiFi. Is it possible to generate the CCV_Drive_Sync.zip library file another way, maybe on a computer?

  15. how can you download comics on the net and where can i go to find the info for filling in the parameter fields and which is the right one to chose

    • You have to use your own comics file (cbr, cbz, pdf, epub or image files). The app can open files stored on your device (internal memory or SD-card) or on network (like Google Drive, DropBox, PC on windows using Samba, …).
      Where do you store your comics file ? On your device or on network ?

  16. Hello, could it be possible to add ownCloud support? I love the way you can access the Google Drive files on my android tablet. And would love challenger even more if I can do the same with ownCloud.

  17. Ryan, I just tried it in owncloud. It works ! You just have to add “weddav directory”.

  18. Bonjour.
    Je viens de télécharger votre application. Auparavant, j’utilisais Moon Reader pour lire des comics et j’utilise Aldiko pour lire des romans.
    J’apprécie la partie BD de Challenger Comics Viewer. Il suffit juste de penser à faire des dossiers bien organisés avant importation (ce qui n’était pas mon cas au départ :-)).
    Par contre, est-il (ou sera-t-il) possible, lors de l’importation de fichiers (notamment pour les romans) de modifier les noms (auteur, titre voire meme du fichier directement) afin de classer les livres autrement que par date ou par nom et/ou de créer des étiquettes pour regrouper des livres d’auteurs différents. Un exemple? Kevin J. Anderson a écrit dans “Les Royaumes Oubliés”, “Avant Dune” et “Star Wars”; j’aimerais avoir accès à ses oeuvres en sélectionnant son nom mais j’aimerais aussi pouvoir le voir aux cotés d’Ed Greenwood dans “Les Royaumes Oubliés” ou de Frank Herbert dans la collection “Dune”.
    Dernière chose, lors de l’ouverture de l’appli, peut-on avoir un écran plus beau que les 6 espaces gris sur fond noir correspondant aux diverses actions possibles? J’admets que j’aime bien le look bibliothèque avec des étagères…
    Merci beaucoup de votre temps et de votre réalisation.

    • Bonjour,
      Tout d’abord merci pour ton commentaire.
      Pour ce qui est de l’edition des infos des fichiers, cela n’est pas possible pour le moment. Ca fait partie des changements que j’ai prévu (dans un premier temps, gerer les metadata et ensuite pour les modifier).
      Pour ce qui est de la page d’accueil, il est possible d’afficher la bibliothèque au démarrage ou bien de charger automatiquement la dernière BD lue (avec Options => Systeme => Rechargement automatique).

  19. Sooo… when are you going to add bookmarks? You said you were going to do it back in 2013:

    Hi Medhi,
    For now it’s not possible to add bookmarks. I will try to add this feature for the next release or the release after.
    Thanks for your feedback.

    • Bookmarks support was added few months ago. You just have to use “Add bookmark” and “Bookmarks” menu items. Both actions are available only for comics and books stored in library. Does it match your needs ?

      • I’m running this on Android 4.4 and I have the comics added to the library and I don’t see a “Bookmarks” menu Item. I see “Do Nothing, Exit, Open, Open Web, Display library, Display Options, Prev Page, Next Page, Auto Scroll Backward, Auto Scroll Forward, Toggle Full Screen Mode, Switch to Home View.” This is Challenger 2.01.14.armeabi-v7a

      • It seems you are not using the correct menu. I was speaking about the “three dots” menu (top right menu button or physical button dependingbof your device), not the “long press” menu. Do you find the correct menu item ?

  20. Hi, the hierarchy for files in the SD card is ok:
    example

    Library–
    —— Batman
    ————- Folder 1-100
    ————————– 1.cbr
    ————————– …cbr
    ————————– 100.cbr
    ————- Folder 101-200
    ————————– 101.cbr
    ————————– …cbr
    ————————– 200.cbr

    But if I have the same hierarchy in cloud ( onedrive ), and select the root of onedrive, the library is:

    Library–
    ————- Folder 1-100
    ————————– 1.cbr
    ————————– …cbr
    ————————– 100.cbr
    ————- Folder 101-200
    ————————– 101.cbr
    ————————– …cbr
    ————————– 200.cbr

    without the principal folder “batman”

      • Display mode Folder.
        the problem is only for items in onedrive.

        hierarchy in onedrive is:

        onedrive root–
        —Comics
        —— Batman
        ————- Folder 1-100
        ————————– 1.cbr
        ————————– …cbr
        ————————– 100.cbr
        ————- Folder 101-200
        ————————– 101.cbr
        ————————– …cbr
        ————————– 200.cbr

        but appair without folder “Batman”

        If i use the same hierarchy in sd card, the hirarchy is correct.

        Directory in app:
        FILE: /storage/sdcard1/comics (and inside “batman” “Hellblazer” ecc.ecc., hierarchy ok in library)
        Skydrive: comics (and inside “batman” “Hellblazer” ecc.ecc., hierarchy KO in library)

      • You are right. I reproduced the problem. The problem occurs because there is no “path” in OneDrive, only ids (unique identifier for file and folder), I keep only parent Id (not the full path of file) in Library database so I can’t retrieve file hierarchy using only Id …
        I will try to find a way to fix this (perhaps by adding full path in Library database).

  21. Hello,

    J’ai un bug des plus exaspérants: je lis des comics avec Challenger et il est quelque fois impossible de lire un fichier CBZ (jamais de problème avec les PDF).

    Le problème ne vient pas de l’archive mais bien de l’app: en testant la même archive avec Perfect Viewer (que je déteste que plus haut point) je peux lire l’archive sans souci mais avec Challenger (ou avec comic rack (que je déteste aussi) ou Moon Reader) il ne s’afiche qu’un écran noir ou, au mieux, la première page du comic. De plus Challenger reste figé (impossible de naviguer entre les pages, ça reste bloqué sur la page 1 ).

    Les comics ont été achetés sur storybundle ou groupees, donc ce ne sont pas des fichiers douteux et je ne comprends vraiment pas pourquoi certains marchent et d’autres non alors qu’ils font partie du même lot, et surtout pourquoi Perfect Viewer peut les lire et pas Challenger. Le poids ne semble pas être le problème, des fois un fichier de 20 Mo ne marche pas alors que d’autres du même poids marchent, et d’autres fois c’est un fichier de 50 Mo qui ne marchent pas alors que d’autres tout aussi gros voire plus marchent sans souci.

    Pour info je lis sur une tablete Kobo arc 10 HD, android 4.2.

    Si vous avez une idée/une solution ça serait vraiment salvateur. :/

    • Pourriez-vous m’envoyer un des fichiers qui pose problème (thechallenger@free.fr) ? Je vais essayer de reproduire le problème sur mon appareil en utilisant votre fichier. Merci pour votre aide.

  22. Effectivement, c’était trop gros. :p
    Merci pour sendspace, ça devrait être reçu maintenant.

    • Bon, j’ai fait un test avec le fichier. Je ne reproduis pas le problème (aucun soucis, les 35 pages s’affichent correctement). Est ce que tu peux essayer d’effacer le cache fichier (dans Options => Cache => Effacer le cache fichier) et essayer de ré-ouvrir le fichier ? Est ce que tu peux également me donner les références de ton appareil ainsi que la version d’Android ? Peux tu également me dire quelle est la valeur de l’option “Résolution de l’image” (dans Options => Performance => Résolution de l’image) ?

  25. Hi, I like your app, it meets all my needs (read PDF magazines), even as we enter 2016. The interface looks a bit old, but I can live with it. Function over form I guess.

    My problem is I am using lenovo tablet. In comics or library mode, the screen and thumbnails are all in landscape mode, when I am holding it in portrait mode and the content is in portrait mode. As a result everything looks vertically squashed to 1/3 the size.

    Any way to correct it so everything looks like it supposed to?

  26. Bonjour,
    j’ai un probleme avec un cbr il s’affiche bien sur mon tel, mais sur ma tablette l’image et verte et violette et l’appli plante ! des iées ou un screenshot a vous envoyer ?

    • Pourriez-vous m’envoyer le fichier (thechallenger@free) ? Le plus simple est de d’uploader et de m’envoyer le lien (Vous pouvez utiliser par exemple: http://sendspace.com ou http://dl.free.fr).
      Vous pouvez également m’envoyer un screenshot si vous reproduisez le problème facilement.
      Vous pouvez également effacer le cache fichier (dans Options, Cacher, Effacer le cache fichier). Cela forcera à nouveau l’extraction de la page à partir du fichier.

  27. Hi, I have a question about how to change Library’s source location. I have all my comics in a fileserver through smb protocol but the name of this server was changed. I would prefer just change the url of current source in order to keep my reading status and not load all comics again as a new library. Is that possible?

    And other question is if we can change where covers are stored in order to use SD card.

    Thanks to your great job. Regards.

    • For now, it’s not possible to update/modify existing library. Sorry about that.
      I think the best way to migrate your library is to first export your library in XML file (using Options, System, Export library in XML file). Then, send me the generated file (thechallenger@free.fr) with new server name, I will send you a modified XML file. Finally create a new library using new server name and then import modified XML file, it will update reading status.

      About covers, they are stored in Android Database. You can move app to SD Card if needed (more info: http://www.ubergizmo.com/how-to/move-android-apps-to-sd/).
      You can also move App cache files (files generated by app to speed up display) to sd card using options (in Options, Cache, File Cache location).

      • I hadn’t thought to do this, but I was not able to do by myself when I tried. I send an email with the info. Thanks for all your help. Regards.

      • I did not receive your email … Perhaps your mail was too big. If you want to send big file, don’t hesitate to use sendspace.com or dl.free.fr (you can upload your file and send the link).

      • I did upload the file to Mega hosting.

        The original name of my library server was "Zardoz" (or zardoz, I'm not sure about cases), and the new server name should be "192.168.0.90"

        The url to downlad the library dump is https://mega.nz/#F!RwtDQRwD!ab_DNNyYz947F7VvIyhL9A

         

        Thanks again.

        Best regards,

         

      • I updated your file.
        It’s available here: http://dl.free.fr/fdzCmNHM1
        Can you download it and put in your download folder. Then you can use the “Import library from file” action.
        I think you should deactivate (or delete) your current library to avoid duplicate.
        Does it work on your side ?

  28. Hi,

    Thanks for the app! Greatly appreciated!
    I’d like to know if you plan to add bookmark export feature. It would be very helpful to be able to export all the bookmarks similar to Library export functionality.

  29. hey there great app.i really like it. could you maybe look into adding support for webdav access to mega.co.nz cloud service. i tried many different settings: webdav.mega.co.nz, dav.mega.co.nz and so on but nothing works.

    • Mega does not support webdav access. So it’s not possible for the app to have an access to your files.
      There is an API to communicate with Mega. I will try to integrate it in the app. It’s on my todo list.

    • Hi,
      I added Mega support.
      I need help to test this new version before releasing it officially (on Play Store).
      Are you interested to test it ? If yes, I can send you a test version.

  30. Ye sure I’m happy to help. I have a bunch of comics uploaded to my mega account. Would I need to enter something special in the webdav fields for it to work?

  31. No it’s a new app version with a new menu item (named “Mega”). Mega is not compatible with webdav access.
    You will have to enter your mega login and mega password, then it should be ok.
    Can you send me an email (thechallenger@free.fr) ? Then, I will send you a link to the new version.

  32. Très bonne application. Bugs corrigés
    J’ai cependant des problèmes pour garder mes BD dans le cache mémoire. Dès que je quitte l’application et malgré 1 go de cache je retrouve la bibliothèque vide la fois suivante. Merci beaucoup de me répondre.

    • Bonjour,

      Le cache fichier ne contient pas la bibliothèque. En effet, la bibliothèque est stocké dans une base de donnée (géré par Android).
      Du coup, modifier la taille du cache fichier n’a pas d’impact sur la bibliothèque.
      Le cache fichier est utilisé pour stocker des fichiers temporaire de l’application (des images traité pour être affichées plus rapidement).

      Ou sont stockées vos BD ? Sur le réseau, sur la mémoire interne de l’appareil ou sur une carte SD ?
      Lors de la création de la bibliothèque, est ce que tout les fichiers sont correctement affichés (avec les couvertures) ?

  33. Bonjour,

    Des fois les couvertures sont grises dans la librairie, ou sinon se sont plusieurs pages pendant la lecture. J’ai essaye differents reglages sans succes. Que faire.

    Merci, super app!!!
