Islam & Android: A Fusion of Technology & Theology
Religion plays a pivotal role in the way how people think, behave and lead their day to day lives. Islam is no doubt the fastest growing religion in the United States and the 2nd largest religion in the world. With the advent of smartphones, a modern Muslim can always be at ease to perform their prayers, and other religious practices. There are a number of Android apps on the market that are a great mentor for Muslims, a few of which i would like to mention here:
Islamic Prayer Times. An Android app with azan and prayer time alarms.
Quran Android. This app provides the text of the Quran in Arabic along with translations in a number of languages.
Muslims Pro. For Android phones, this app has an Islamic calendar, qibla direction and Julian dates of Islamic holidays, in addition to the Quran in Arabic and Roman English text along with an English translation.

Things That Cannot Change by Dianne Hackborn
Sometimes a developer will make a change to an application that has surprising results when installed as an update to a previous version — shortcuts break, widgets disappear, or it can’t even be installed at all. There are certain parts of an application that are immutable once you publish it, and you can avoid surprises by understanding them.

Source Code To Display Battery Info & Chart
Following code displays battery-related details on Android phones. I programmed it on Android 1.6. The code still needs some refinement though. And the following code is inspired and extracted from the android sample code for drawings and shapes.
Visitors and members of the blog are warmly welcomed to play with it and refine it further.

Android Development In Visual Studio
Introduction
vs-android is intended to provide a collection of scripts and utilities to support integrated development of Android NDK C/C++ software under Microsoft Visual Studio.
Currently vs-android only works under Visual Studio 2010. Earlier versions lack the MSBuild integration with the C/C++ compilation systems.
The only required component is the Android NDK. Neither Cygwin, Java, nor the full Android SDK are needed to compile and link C/C++ code.
Features
- Compile and link Android C/C++ projects within Visual Studio.
- Integrated development, no makefiles. Works as another 'Platform' type.
- Android settings co-exist within the same VS projects as other platforms.
- Supports static library projects, and links them in if marked as project dependencies.
- Intellisense and 'External Dependencies' correctly pull in Android NDK headers.
- Cygwin install is not required.
- Around twice as fast as using ndk-build under Cygwin. For full rebuilds, and incremental changes.
- Ctrl-F7: compile single file functions, has no dependency checking wait.
- Supports invoking ant after linking, such that you end up with a packaged ready-to-deploy .apk file.

Tutorial: Android & Mind Games
Developing a game on android is a whole new ball game i.e. very different from making database apps. You have to know the logic behind every move. The flow of the program is complex and you also have to keep in mind about the memory issues if necessary.
Mind games are great mind-teasers as well as thrilling to the general smartphone users. Ever wondered what are the essentials that a typical mind game program is comprised of?
We usually have the following: Random Numbers, Timer, and MotionEvent.
Here is a source code for a little game on Android that i named "Reflexo", as it measures one's reflexes :)
