4G download speeds might be typically 5 - 12 Mbps but upload is slower, typically 2-5 Mbps and are about 7 times faster than 3G.Ĥg network users can experience very different data performance depending on the time of the day, weather, whether their data signals are being attenuated by a building structure, weather conditions, how you hold your Android (the antenna needs a clear path to the cell towers) etc. Glad to know your late model phone can, sometimes, work as well as my ancient Android usually works on the network. Android Studio is multithreaded and that may be what you think you need.īetter reception is certainly better Tim. Keep in mind, App Inventor is an asynchronous, single threaded compiler.Īpp Inventor graphics are known to be slow compared to what is possible using Android Studio and java based professional compilers. Re-introduce the app elements one at a time and you might discover the time waster. Remove the Map component and all the extensions and the several Clocks see how it performs. If you want help, please construct an example app (without all your glitz) and post the code so someone can understand what you are asking your cell phone cpu to do. You said what you tried, but didn't show. Your example of quick response downloading from a hyperlink using your PC browser is analogous to using the WebViewer without all the processing you need to display the fish in an image component. You use a Web component in your example to grab the image link, then 'process' the results. You retrieve the image with the Web (you do not use a WebViewer which is fairly fast in both WIFI and network). When you display the image on your app, it appears you use a ScalePictureToFit (slowing the rendering). Your image on the google drive is 320x400 pixels jpeg. NetworkVsWIFI 702×235 24 KB Use the code above to test manually turn off WIFI to check network performance.
