开启Android程序时检测网络与GPS是否打开

// 是否有可用网络
private boolean isNetworkConnected() {
ConnectivityManager cm =
(ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo network = cm.getActiveNetworkInfo();
if (network != null) {
return network.isAvailable();
}
return false;
}

// Wifi是否可用
private boolean isWifiEnable() {
WifiManager wifiManager = (WifiManager) mContext
.getSystemService(Context.WIFI_SERVICE);
return wifiManager.isWifiEnabled();
}

// Gps是否可用
private boolean isGpsEnable() {
LocationManager locationManager =
((LocationManager) mContext.getSystemService(Context.LOCATION_SERVICE));
return locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
}
