Android operator and Network Type Analysis For some requirements, you need to obtain the carrier and network type, and analyze the carrier and network type. First, we will throw some nonsense definitions: GSM: The Global System of Mobile communication is a well-known GSM, the most widely used Mobile phone standard. CDMA: Code Division Multiple Access (CDMA) is a new and mature wireless communication technology developed from the Spread Spectrum Communication Technology, a branch of digital tech

/(double) dens; Double hi= (double) height/(double) dens; Double x = Math.pow (wi,2); Double y = Math.pow (hi,2); Double screeninches = math.sqrt (x+y); Again, the code above needs to be able to get an activity. Third, get the app name public static string Getappname { string appName = ""; try { Packagemanager Packagemanager = Context.getpackagemanager (); ApplicationInfo applicationinfo = Packagemanager.getapplicationinfo (Context.getpackagename (), 0); AppName = (
