“App not Installed” Error on Android When Updating to Newer Version

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

It turned out that though I had android-versionCode code in my config[…]

Phaser Cordova Mobile App Crashing on iOS

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

 

Path must be a string. Received undefined

It has been a couple months since I last used Intel XDK and a lot has changed since. I just tried to compile a demo HTML5 + Cordova Android app which was exported using Intel XDK version 3987 and got the following error while trying to add android platform to the app using cordova command line. To see how compiling is done, check this blog post. Discovered plugin “cordova-plugin-whitelist” in config.xml. Adding it to the project Installing “cordova-plugin-whitelist” for android This plugin is only applicable for versions of cordova-android greater than 4.0. If you have a previous platform version, you do *not* need this plugin since the whitelist will be built in. Saved plugin info for “cordova-plugin-whitelist” to config.xml Error: Path must be a string. Received undefined After this error you wont be able to compile the APK. Some research on google got me to this thread which eventually worked. https://stackoverflow.com/questions/46730465/can-not-add-cordova-platform-on-cordova-7-1-0-path-must-be-a-string To fix[…]

Failed to remove a plugin from Intel XDK

In the latest Intel XDK version 3987 I was not able to remove the third-party plugins from HTML5 + Cordova app. Whenever I try to remove a plugin, it failed with the error message Uh oh! Path much be a string. Received undefined I found a workaround @ https://software.intel.com/en-us/forums/intel-xdk/topic/733620 Since Intel XDK is no more into development phase, I think this is the only way as long as this works. Steps are simple. Go to development tab and expand plugins folder there. Delete the third-party plugin and all dependent plugins. Also, delete fetch.json. Then go to Projects tab and delete the plugin from there under Plugin Management. Finally restart XDK.  

Cordova Plugins: Review Unnecessary Permissions

If you went through the article on adding social sharing feature in HTML5 game using Intel XDK, it seemed like a simple plugin which should not require any permission but after adding the plugin and few more other plugins I found that WRITE_EXTERNAL_STORAGE permission was added in my android app so I checked all plugins one by one to see which plugin is adding what permissions and found out that WRITE_EXTERNAL_STORAGE permission was being added by social sharing plugin. When I checked developer notes (quoted below) I found that the permission was not required in my case, since I was not fetching any remote images for sharing. For sharing remote images (or other files) on Android, the file needs to be stored locally first, so add this permission to AndroidManifest.xml: <uses-permission android:name=“android.permission.WRITE_EXTERNAL_STORAGE“ /> In fact it was just a simple play store URL which I was sharing in my app so[…]

Add AdMob Ads to HTML5 Game using Intel XDK

The steps are as following Open your app in Intel XDK and go to CORDOVA HYBRID MOBILE APP SETTINGS section Click on “Add Plugins to this project” and search for the plugin “cordova-plugin-admob-free” in npm. Click “Add Plugin” which adds plugin to the project. Open your index.html and add following code

Replace banner and interstitial ad code id with yours. The code in the example is given by Google to test the ads which displays placeholder ads for testing. This can be used during development and testing. Replace it with your ad codes for release. Another thing to note here is that interstitial ads can be loaded before it is actually called for display. Make sure to set “autoShow” to false to disable automatic load of interstitial ads. Default value for this flag is true so if this value is not set to false then ads will be automatically displayed once “prepare” is called and[…]
