How to Zoom With one Finger on Any Window that Supports Pintch to Zoom

While extremely intuitive and innovative, the pinch-zoom gesture can be difficult at times and for certain people. Be it due to a user’s physical limitations or one-handed device operation, the gesture isn’t always the most convenient. And while Google Maps has incorporated an alternative zoom gesture for some time, there isn’t always a good alternative gesture for application zoom gesture functionality in every app.
We aimed to change this with Assistive Zoom. As you can gather from the app’s title, Assistive Zoom assists users in sending the pinch-zoom gesture signal from just single-finger operation. To make the application to be useful to a wide range of users, Assistive Zoom is highly configurable in sensitivity, trigger options, and zoom options. It currently offers three trigger icon style options, as well as fine control of zooming scale and user-selected triggers.
The application is compatible with Android devices running Froyo and greater. As this is a system-wide modification, root access is required. Want to give this a shot on your own device? Simply head over to the modification thread to get started.

[APP][2.2+]Assistive Zoom - One finger zoom control in any browser (ROOT) test needed

NOTE: This App is ROOT required

First time on Android device. This App allows you to send pinch to zoom in/out event on any window with JUST ONE FINGER. So when you are only one hand free, and want to zoom in a web page, Assistive Zoom can help you big time. Just hold on the floating zoom button of Assistive Zoom and move up/down to control the scale factor. This App works in any pinch to zoom enabled window or App.

Since this is my first release and due the the fragmentation of Android system, I am not sure it works on all kind of platforms. I have tested on my 2.2, 4.0, 4,1, 4.2 devices without a problem. So please help to test if it works on your device. If you experience any problem, please let me know. Also, any suggestion is welcome.
