details of signal bar in android
<p>In android emulators' <strong>GSM</strong> signal bar has four division.  May i know how much of signal is denoted by each division.  In android signal level is between 0-31.  What is the criteria for filling all divisions in signal bar.  I already simulates signal level in my program, but it has 5 divisions. </p>
