Pinpic : a new mobile app

I am happy to announce that I have published a new application on Google Play, named as Pinpic. It is under photography category. It is a very useful and user-friendly application to specialize photos by pinning anything on them. What it does may seem quite common but in practice it has new and unique features. What are they? Well. Pinpic enables users to write on pictures as many as they want with different properties. Their style(e.g. italic, bold, text color, alignment etc) are easily configurable. It not only has great fonts for latin alphabet but also supports Cyrillic, Hangul, Katakana and Hiragana with many fonts. What if I want to use my own drawings on a photo? Pinpic is here for you. You can draw any thing as many as you want. By resizing, changing thickness and color of lines, drawing style; you can make your drawings more enthusiastic. This feature is just on the way. Wait, there is more. Motifs are great arts to pin on your photos. They will definitely create so cool...

Why shouldn't static variables be used as global variables in Android development

For mobile devices with small memories, memory usage and care of applications is essential. If an application uses images, it can easily result a memory leak if they cannot be collected by garbage collector. A reason why GB couldn't collect unused objects is that those objects refers to a static variable. So, if you are setting a property of a local variable with a static one, you need to be double careful.
