i use <strong>HoneyView</strong> and <strong>Picasa,</strong> think are the best.
for Picasa no official website ... google dropped the project..
and for downloading manga i discover some powerful engine named <strong>HDoujin Downloader</strong> .... it make the life more easier ...
no ads here just my fav app ....
peace, love and some candy.
I've been reading manga on my Kobo for about a year now and the way I do it is by downloading through this application: https://doujindownloader.com/. It can download manga from a huge assortment of websites and then convert it to for example .CBZ. It has a lot of nice features and isn't too hard to learn. I've had two problems with this process though:
1, in my experience when downloading from Mangadex there are often missing chapters so i'd suggest another site and
2, it seems that my e-reader at least (Kobo Clara HD) can't handle too large .CBZ files so for example when reading Berserk I had to split the 3,26 gb large file inte to two which is easy to do in the application I linked.
Well... it's pretty straight forward. You go to the site, fetch the link, past it, click add. The link is added to the queue below, than you click the "play" button above and it goes off.
Have you read their help section?

Haha that's one thing I really wish I COULD help you with. I have PDFs of the light novels but not the manga.
But, I have heard good things about these:
Supposedly with doujindownloader you can input the kissmanga table of content url and it should work for all chapters:
i.e. http://kissmanga.com/Manga/To-Aru-Kagaku-no-Choudenjibou
Then you can just download every chapter off kissmanga.
I haven't tested it myself so if it doesn't work or if something goes wrong it's totally not my fault. Let me know how it goes! :)
P.S. Trying to read off an android device, outside of a tablet, is going to be hard. And you're probably going to end up getting these as strings of pictures. for each chapter. What you COULD do however is use www.ilovepdf.com to convert the images into PDFs and then load them onto your phone using dropbox or via email, then save to your default android PDF reader.
Let me know how this goes for you! I wish I could have just given you a download link. :P
Edited: Out my private Dropbox link.
