判断真机还是模拟器

TelephonyManager telmgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);                  String deviceID = telmgr.getDeviceId(); 
                boolean isEmulator = "000000000000000".equalsIgnoreCase(deviceID); 
 
                
                if (isEmulator) { 
                    ((myApp) getApplication()).setBitmapX(BitmapFactory.decodeFile(imageFileName)); 
                } else { 
                    ((myApp) getApplication()).setBitmapX(BitmapFactory.decodeByteArray((byte[]) args[0], 0, ((byte[])args[0]).length)); 
                }
