How to get cell service signal strength in Android?

Question

I am trying to write a very simple Android application that checks the signal strength of the current cell. So far, I have only found something called getNeighboringCellInfo(), but I'm not really sure if that includes the current cell.

How do I get the CURRENT cell signal strength in Android?

Does getNeighborCellInfo() get the current cell? It doesn't seem like it based on the results that I have been able to get with it. Here's my current code:

List<NeighboringCellInfo> n = tm.getNeighboringCellInfo();  //Construct the string String s = ""; int rss = 0; int cid = 0; for (NeighboringCellInfo nci : n) {     cid = nci.getCid();     rss = -113 + 2*nci.getRssi();     s += "Cell ID: " + Integer.toString(cid) + "     Signal Power (dBm): " +              Integer.toString(rss) + "\n"; }  mainText.setText(s);

create a PhoneStateListener and handle the onSignalStrengthChanged callback. When your app is initialized, it should give you an initial notification. This is in 1.x. in 2.x, there's an open issue about this.
