Hi, I have just released my new application, called Plastic Identification Codes.
I've built this app mostly for fun and I will be happy if you comment it.

Description
You have probably noticed on most plastic products a recycling symbol with 1, 2, 3, 4, 5, 6 or 7 along with letters.
So what are these exactly?
The SPI resin identification coding system is a set of symbols placed on plastics to identify the polymer type. The symbols used in the code consist of arrows that cycle clockwise to form a rounded triangle and enclosing a number, often with an acronym representing the plastic below the triangle. When the number is omitted, the symbol is known as the universal Recycling Symbol, indicating generic recyclable materials. It was developed by the Society of the Plastics Industry (SPI) in 1988, and used internationally.
With this application you can:
- search for plastic codes
- see description, statistic about them
- see the formula for them
- what products are made by them
- see which are safe to use.

Features of the program:
AntiSteal phone module protects against theft. (module monitors the number of SIM cards currently in use to define permitted to operate with a phone card numbers. if the number of cards will change to undefined as an acceptable application sent to the following telephone number sms `az information, switch mode hidden (which is invisible to the user) and can transmit to a specific phone number, all received sms `yi made the calls. In addition, thanks to the GPS positioning can quickly locate the stolen phone.)

A pair of security researchers have recently unveiled an interesting new keylogging method (PDF Research Paper) that makes use of a very unlikely smartphone component, your gyroscope.
Most smart phones now come equipped with gyroscopes, which can be accessed by any application at any time. [Hao Chen and Lian Cai] were able to use an Android phone’s orientation data to pin down what buttons were being pressed by the user. The attack is not perfect, as the researchers were only able to discern the correct keypress about 72% of the time, but it certainly is a good start.
This side channel attack works because it turns out that each button on a smart phone has a unique “signature”, in that the phone will consistently be tilted in a certain way with each keypress. The pair does admit that the software becomes far less accurate when working with a full qwerty keyboard due to button proximity, but a 10 digit pad and keypads found on tablets can be sniffed with relatively good results.
We don’t think this is anything you should really be worried about, but it’s an interesting attack nonetheless.

Hello
This is the first app I wrote for Android on my spare time. It is not groundbreaking or super complex, just a resistor calculator with reverse search capabilities. It is free on the market, I am not looking for any commercial profits but rather just suggestions (especially the UI, which I am weak at). I am looking to writing a new Grade Management App which can let a person record all their grades/weighting/courses and provide performance analysis, etc. But before I get into that, I really want to learn more about UIs from the community because I know it can be a lot better than the resistor app. So onto the app itself:
* 4 and 5 Band Resistor Support *
* Supports Reverse Lookup *
This Resistor Tool can display the resistance value based on the color bands. In addition, it can also display the resistor colors based on an inputted resistance value.
In other words, whether you have a resistor and want to find out its value or vice versa, this app can get it done.
I am a starter in Android Programming so all suggestions and ideas are welcome, thanks!

Here's a daydream that old school hackers out there might recognize if you've ever used CDE on Unix or VMS. This is an Android port of Jeff Butterworth's xswarm. This was mostly done as a learning project and I still have a few questions resulting from it. Though for now it's done, working, and I think I've added enough options. I'll take bug reports and pull requests but don't expect too much in the way of additional features.
Anyway, here's some shots.

--- Non-devs can skip the following questions. ---
Is there a color picker library that uses fragments and also allows hex entry? lomza/android-color-picker looks like one of the better ones, though I'd really prefer something with text input for exact values as well.
I'm also trying to come up with a way to programmatically pull in resources so I don't have to do ugly enumeration such as this (see TODO sections). The EditTextPreference dialogs do bounds checking before updating the summary field, but one thing that throws a wrench (or IllegalStateException) into things is that EditTextCheckBounds isn't attached to the Activity so you can't call getResources() within that function without jumping through a lot of hoops.

This program serves as a mobile assistant to an engineer.
First version of the program provides solutions for the analysis of the nine single-span beams.
The most popular type of beams for designing covers and floor are selected as default sections
Double T normal beams in accordance to СТО АЧСМ 20-93, HEA, HEB, HEC, HEM, IPE, old russian and german standarts (before 1917 year!) and channels in accordance with GOST 8240-97, UPE, UPN. The calculation results depend on the steel grade, the required deflection and section type.
program uses the following steelgrades: steel S245, steel S255, steel S345.
The calculation and selection of the beams are performed on the assumption that the upper belt of beams tied along the entire length.
New in version 6 (1.0.5)
In the results of analysis and the series 2.440-2 Issue 1 tab added information
about mounting beams to columns and other beams according to joints 20 ... 25 of 2.440-2 Issue 1 (hinge joints with overlays and bolts M20 class 5.8 and 8.8).
