I recently updated an old Cordova Android app and tried to install it on my Android phone which had previous version installed already and the install failed with the message “App Not Installed”. Other than updating Android version and couple of plugins, everything else was same old and I had correctly changed “android-versionCode” as well as “version” to higher number so nothing looked wrong but I suspected it had something to do with either the version code or the certificates I was using to sign the app so I decided to look into the previous APK file and try to find something out. We can use AAPT tool to look into APK files which can be found in build-tools\<buildToolVersion> folder (for ex, C:\Program Files (x86)\Android\android-sdk\build-tools\23.0.1). Go to the folder and run following command in the command prompt aapt dump badging myapp.apk It turned out that though I had android-versionCode code[…]

Microsoft is now providing Visual Studio Emulator for Android which can be used to deploy, test and debug Android apps. It also comes with a standalone version which can be used for quickly testing your APK files without needing Visual Studio which is very helpful for hybrid apps which are not built using standard development tools. For example if you have built your app using cordova and are looking for testing your app on a few emulators and are short of actual physical devices then this emulator comes handy which currently has support up to Marshmallow (API level 23). Download the standalone emulator installer from https://aka.ms/vscomemudownload Click on the installer and go through the installation process. It uses Hyper-V for running the emulator so it may ask you to confirm on activating it. Once it is installed you can open the emulator by searching for “Visual Studio Emulator for Android” in your windows[…]
I recently tried to upgrade Cordova app which was last compiled almost an year back and got the following error Error: Android SDK not found. Make sure that it is installed. If it is not at the default location, set the ANDROID_HOME environment variable. I turns out that I had updated Android SDK version on my PC during that time and all I needed to do was to update the platform version in the app as well. Using Node.js Command Prompt and cordova commands, check the installed platform in the app using the following command cordova platform version android Update the installed platform version in the app using the following command cordova platform update android While upgrading the app additional issues I faced were related to plugins not being compatible with the new platform version which were fixed by simply removing the plugins and re-adding it which in some cases[…]
Use this method to trim JS object values and display only the required info (which I do a lot for deugging purposes). Here is what gives me a concise info I am looking for while debugging my code in JS. function trimInfoInArray(array, props) { return array.map(function (item) { var obj = {}; for (var i = 0, len = props.length; i < len; i++) obj[props[i]] = item[props[i]]; return obj; }); } function trimInfoInObject(object, props) { var obj = {}; for (var i = 0, len = props.length; i < len; i++) obj[props[i]] = object[props[i]]; return obj; } Now the example on how to use it is as following var player1 = {id: 1, name:’Tom’, Age: 30} var player2 = {id: 2, name:’Jon’, Age: 28} var players = [player1, player2] console.log(JSON.stringify(trimInfoInArray(players, [“id”, “name”]))); console.log(JSON.stringify(trimInfoInObject(player1, [“id”, “name”]))); With some objects having hundreds of properties and printing those values and searching for just the[…]
I recently decided to give it a shot and see what kind of interaction do I get with this ad. Unfortunately it comes with certain issues and won’t work on any browser other than Chrome. I tried it on Firefox, Chrome and IE11 and the ad loaded only on one browser (Chrome). I recehed out to PropellerAds support team which after a few iterations admitted that it is working on Chrome only. IE displays the following error Firefox displays a different error
I recently planned to compile my Phaser games for iOS App Store. These games were build using Cordova CLI and have already been published on Android Store so I already have a functioning game which was to be ported to iOS. I decided to document the steps I had to follow to get my game compiled and published to iOS App Store. You can develop the game on any platform of your liking but in order to compile and publish these games to iOS App Store you do need to have a Mac. It can not be done from Windows or any other platform. Steps to compile the game: Download MacOS installer for Node.js and install it on your Mac. Go to App Store on your Mac and install latest version of XCode. You need XCode to build the game. Open Terminal console (Finder -> Applications ->Utilities) on your MacOS and install cordova using npm utility of Node.js by[…]
Cordova Mobile apps display a white background right after Splash screen. This happens because WebView is loaded before our app is initialized. I tried many suggestions such as setting AutoHideSplashScreen to false and then call navigator.splashscreen.hide() in deviceready function which did not work for me. It gets called before WebView is even loaded. After trying a lot of things I finally had to look into the main view controller code which is automatically generated by Cordova (I am using Cordova 8.0.0). Go to MainViewController.m file in the platforms/ios/CordovaLib/Classes folder and look for following code – (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view from its nib. } Add the lines highlighted as below. I used a transparent Splash screen (which gives black background while splash screen is shown) and changed the background color of the WebView to the color which matched with my app’s background color. – (void)viewDidLoad { [super viewDidLoad]; self.webView.opaque=NO; self.webView.backgroundColor =[…]
I recently decided to compile Phaser games to iOS and publish to The App Store. The games were already published on Google Play Store for Android and worked without any issues. I faced few issues after compiling Phaser games for iOS. The first issue which I faced was the game crashing randomly on iOS. After doing further research I found this article on Intel XDK forum which turned out to be the reason for crash. The games were written a while back with older versions of Phaser and I did not get time to upgrade and test this with newer versions of Phaser (CE and higher) so I decided to try the fix specified in this thread and voila, it worked just fine. Here is the code which I borrowed from the thread var mygame; window.onload = function () { mygame = new Phaser.Game(window.innerWidth, window.innerHeight, Phaser.AUTO, “mygame”); mygame.state.add(“Boot”, Boot); mygame.state.add(“Loading”, Loading); mygame.state.add(“MainMenu”, MainMenu); mygame.state.add(“TheGame”, TheGame); mygame.state.start(“Boot”); function onPause() { if(!mygame.paused)[…]
