Mike Szczys is a professional musician but spends all his free time working with hobby electronics. As Contributing Editor for Hackaday.com he became interested in Android as some of the early hardware hacks started popping up on the Internet. What followed was a gradually rising addiction to all things Android.

Using Internal/Hidden Classes of the Android API

Pssst... over here. Yeah, did you know about the Hidden Android Classes? Shhh... it's a secret. They let you do stuff you otherwise couldn't. You can read internal data, like the text message database stored on a phone. You can also gain lower level access to the hardware in order to extend your app's access...

Weather App by Example Teaches JSON, HTTP, and API Use

Developers who are just getting started can leap through the learning curve by reading code written by more experienced programmers. It becomes even more useful if you can read an explanation of what each code chunk does, like with this weather app tutorial. Francesco Angola, who also wrote that guide on using Httpclient, has done...

Flash Custom ROM and Recovery to Samsung Galaxy S 4

After reading about Dan Rosenberg's bootloader exploit for the Samsung Galaxy S 4, I figured it would not be long before someone would craft a package for loading custom ROMs. Of course, I shouldn't be surprised that Dan is the one who figured it out. You may know him better as XDA Recognized Developer Djrbliss. In his...

XDA University: Crafting Recovery-Flashable Packages

Those of us who use Linux on a day to day basis don't think twice about sinking our fingers into the system files that govern how our devices perform. For instance, I use an LG L9 and was quite comfortable playing around with the way my SD card was being mounted in order to improve...

Preventing App Piracy: Join the Discussion

The topic of piracy is always a touchy subject, but I feel that the grass roots style of Android development has created an environment that should be free of piracy. Almost every task one might perform with an Android device can be completed with a free app. And the apps for sale usually are very...

Coloring Your Logcat World

Getting feedback for your app during development is as simple as adding logging info where necessary and looking for the output in logcat. But if there's a lot going on, the task of actually finding the lines can get a little sticky. Logcat does have a rudimentary filtering feature, which was covered in a recent...

HttpClient Tutorial to Upload and Download with Your App

Developers wanting to interact with the Internet need to choose a package to do the heavy lifting for them. A very common route is to use the built-in HttpClient. The documentation is fairly complete, but it's a daunting to get started if you've never used the package before. Take a look at the HttpClient tutorial that JFrankie recently posted.  I find...

Decompile, Recompile, and Sign APKs by Example

Last month, we saw a new tool that made it painless to edit the contents of Classes.dex. If you were drawn in by that prospect but couldn't quite get the pieces to work, I think you'll appreciate following the example that XDA Recognized Themer/Contributor Rizal Lovins put together. He takes one step back to look at the...

Open Source Apps List Shows How Other Devs Do It

Working with a team of developers can be great because you have someone to talk to when you hit the coding wall. If you don't have that luxury, you can still learn how other programmers do things in order to sharpen your skills. That's what XDA Recognized Contributor coolsandie had in mind when he started his list...

Unlock the Verizon Galaxy Note 10.1

Owners of the Verizon variant of the Samsung Galaxy Note 10.1 tablet will no longer feel left out, thanks to the unlock package that XDA Elite Recognized Developer AdamOutler posted late Friday night. Although he takes issue with the word 'unlock,' preferring to call it a 'jailbreak' because that term is exempted by the DMCA. The process couldn't...

Nook HD Finally Gets Official Play Store Support

We understand that companies want to keep tight control of their products and how they're used. But it kind of makes you shake your head when this is done at the expense of functionality. Case in point is the current generation of Barnes & Noble tablets: the Nook HD and Nook HD+. They shipped without built-in...

Samsung Galaxy S 4 Bootloader Unlocked

Dan Rosenberg has done it again... Well, he claims to have unlocked the Samsung Galaxy S 4 bootloader, giving only this slightly blurry image as proof. But anyone who's been paying attention will know that Dan, aka XDA Recognized Developer djrbliss, is good for his word. The news comes via a set of Twitter posts over the...
