how to recover songs from a corrupted shazam library in android when upgrading my phone recently and trying not to lose anything, my shazam library got corrupted. interestingly, i could still tag just fine, but then noticed later that i couldn’t actually look up my previous tags — any time i tried to open the list, the app crashed a second later.
if you’re in the same situation, here’s a step-by-step tutorial to recover shazamed songs from a corrupted library:

open Root Explorer (or a similar root-enabled app) and navigate to /data/data/ (or any directory starting with the name “com.shazam”, depending on your version).
open the /databases subdirectory and copy library.db to your computer (either by copying it to your “normal” internal storage and transferring, or by sharing directly from the app). [more…]

how to fix contact names in viber after data transfer or restore when you factory reset your android phone or switch to a new smartphone, there is unfortunately no easy way to transfer your existing viber messages, received files etc. if you’ve got your mind set to it, there is an manual to migrate viber. the downside of this manual is that upon fresh setup of your android phone, your android contacts may change device-internal IDs, which are used to connect viber contacts with your phone contacts. as a result, messages and threads may be randomly assigned to other contacts in your address book, even if they don’t have viber accounts.

here’s how to manually fix the problem and correct contact names in viber: [more…]

how to build a digital photo frame with wifi and dropbox using an android tablet for 40 dollars before leaving the country for an extended period of time, i was looking for a way to stay in touch with my parents that would be uncomplicated and effortless for them: they shouldn’t have to start their laptops/phones, open an app and write to see what’s been going on in my life lately. i would rather just “be around”, the way you can passively stay in touch with some friends on facebook without losing actual contact, but my parents aren’t on facebook.
the best way i could think of to achieve this sense of “being around” would be a digital photo frame that can be updated wirelessly. however, it turns out that wifi-enabed digital photo frames are quite expensive (for what they do), rather hard to get (in europe), and usually subscription-based. they also don’t work very well according to customer reviews, or their online service ends up being discontinued not long after product launch, or both.

thanks to the popularity and ubiquity of tablets, though, there is an easy way to create your own digital photo frame that can be updated wirelessly by simply copying images to a dropbox folder, and it can cost you as little as 50 dollars – or even less if you have an old android phone or tablet lying around!

how i fixed the problem of a nexus 5 being stuck in "turning on wifi" [solution] after a recent crash both in software and hardware terms, my nexus 5 running android lollipop 5.0.1 could no longer activate wifi. when touching the toggle, it would just show “wifi turning on”, but it never got around to actually scanning for wifi networks or even displaying its mac address.
after quite some online research i tried toggling aeroplane mode, deleting /data/misc/wifi (root), doing a factory reset, upgrading to the newest android version (lollipop 5.1.1), flashing other ROMs and kernels, etc. but nothing seemed to work.
since there was also a physical drop involved, i opened the N5 to check if there was anything noticeable in the internals, e.g. the wifi antenna connector being loose, but nothing was obvious. there were also several reports of google replacing wifi-faulty nexus 5 handsets under warranty due to a “hardware” or “motherboard” issue, but i wasn’t quite ready to give up yet.

Google Authenticator in a world where more and more of our personal life is taking place on the web, a strong password is the very least you can do to keep your stuff safe from others.
about a year after an online journalist had his entire digital life deleted by hackers, many online services including google, facebook, dropbox, and lately even apple, microsoft and twitter, have implemented two-step authentication (or two-factor verification). this means that there’s an optional, extra step that you can activate to verify your identity during login – using a special, variable code that’s e.g. time-coded or individually texted to you.

if you don’t have two-step authentication activated for your email, online banking, google account, apple ID, and even your social media accounts, you should do so right now. [more…]
