Windows 10 App :Host Defined Policy: Inline Script. Resource will be blocked.

I recently ported one of my java script projects to Windows store app and got the error as following CSP14321: Resource violated directive ‘script-src ms-appx: ‘unsafe-eval’ blob:’ in Host Defined Policy: inline script, in ms-appx://13bdc914-5111-4c95-a5e6-82029c5105ec/index.html at line 21 column 12. Resource will be blocked. If you have something like the following, it won’t work

Since I was using jQuery in the project, I simply used jQuery to bind click event to the element

and Voila, everything works but I had many pages which had this reference and I had to make this change to all pages. After some research I found that there is an alternate way which is much faster to change. By default ms-appx:/// protocol is used in store apps to fetch the content. For web apps specify a specific protocal ms-appx-web which is then used for the app. This can be done by changing start page from index.html to ms-appx-web:///index.html[…]

Quick Tip

Tip of the day: Blank href in html A link

When you are using <a> link and want to bind it with onclick event in stead of href location, it can be set to # as following

As you know setting href to “#some_id” is an approach used to link content inside the page so if you are using above approach, it will make the page jump to top which is not an elegant solution. There is an alternate way which is much better as it does not make page jump.

Simple and elegant..  

Error: An invalid APK was received. Not a signed jar file.

When I tried to upload APK file to Aptoide store which was built using cordova and signed for the release version, I got this error An invalid APK was received, does not seem to have all files correctly signed. Please verify apk signature and try again. Signature error: Not a signed jar file The same APK was fine when uploaded on Google Play Store. In order to fix this problem I had to create an unsigned release version of the APK using cordova and then sign it using jarsigner utility. In order to create unsigned release version of the APK, following command can be used

Jarsigner utility comes with java sdk and can be found @ your JDK bin folder (for ex, C:\Program Files\Java\jdk1.8.0_131\bin). The command which can be used to sign the APK is as following

Replace android.keystore with your keystore file name, password with the keystore password, and[…]

How to avoid screen flicker when embedding responsive Phaser game in Bootstrap site

Phaser games can be responsive and will fit in the available space which makes it easy to embed in variety of devices with different sizes. When Phaser games are embeded in a Bootstrap site which is responsive, there can be some flickering on the web page when game is initially loaded. When Phaser games are loaded, it loads in the actual size it was created in and afterwards CANVAS is resized to fit in the available space. The example below is a bootstrap template in which Phaser game is embeded in half of the screen and remaining half screen has some other content. Click the link to load the page to see how the game is being resized to fit in the available space. To make the game load in a nice manner without visible resizing, we need to intially hide the div in which game is loaded. In Phaser boot method we can[…]

Manage Amazon Promotions in ASP.NET Application

If you are into affiliate marketing then you must be getting promo codes from your partners which are promoted on various platforms. For ex, Amazon publishes promo codes for Associates which can then be pormoted by the Associates and they get a cut from the sales. Its a nice way to boost conversion and earn commission. Associates share the link to temporary promotion pages which is tagged with their affiliate id. These promotions run for a short duration and need to be managed more frequently by adding/removing them from your site almost on a daily basis so it makes sense to have a small database at your end which you can use to manage it at your end and it can also take care of the promotions which have ended. If a promotion has ended, Amazon takes you to the deals page when a promotion link is clicked but it makes[…]
