I was surprised to find out that there were no decent widgets for showing signal strength in the Android market. I was not able to find any widgets that provided all the functionality I was looking for so I created my own. Here is what I created:
- 10-bar visual signal strength
- Numeric signal strength (dBm)
- Network Operator
- Data activity indicator
- Network Type indicator
- Supports Android 1.6 - 2.2 (hopefully...I have 1.6 so I have only been able to do much testing on that platform).
