Google Android Play Store Target API Requirement Change

From Google:

Hello Google Play Developer,

This is a reminder that starting November 1, 2019, updates to apps and games on Google Play will be required to target Android 9 (API level 28) or higher. After this date, the Play Console will prevent you from submitting new APKs with a targetSdkVersion less than 28.

Configuring your app to target a recent API level ensures that users benefit from significant security and performance improvements, while still allowing your app to run on older Android versions (down to the minSdkVersion).

Android 9 (API level 28) introduces a number of changes to the Android system. The following behavior changes apply exclusively to apps that are targeting API level 28 or higher. Apps that set targetSdkVersion to API level 28 or higher must modify their apps to support these behaviors properly, where applicable to the app.

To target the api in your Cordova app set these min and target version in config.xml

    <preference name="android-minSdkVersion" value="23" />
    <preference name="android-targetSdkVersion" value="28" />

iOS Deprecated API Usage Warning Ionic using UIWebView

Apple will no longer support web apps that use UIWebView. The apps and libraries need to be migrated to use WkWebView.

The latest Ionic already uses WkWebView, but several Cordova plugins still rely on UIWebView which is a problem.

https://ionicframework.com/docs/v3/wkwebview/

If you’re using Ionic you need to upgrade to iOS Cordova 5

cordova platform remove ios
cordova platform add ios@5.0.0

Also you might need to remove additional plugins that use UIWebView such as inappbrowser.

cordova plugin rm cordova-plugin-inappbrowser

More information about the breaking changes can be found here:

How To Build Production and Release Version of Ionic App

To make the production and release version of Android app using Ionic run:

ionic cordova build ios --prod --release

This should run the same as the expanded version:

ionic cordova build ios --minifycss --optimizejs --minifyjs --release

You may need to run with sudo in front of the command if you have permission issues.

For iOS builds the –release flag does not seem to do anything in my testing. I could not find any official documentation explaining what this flag does to iOS builds.

For more detail visit the ionic documentation on building
https://ionicframework.com/docs/cli/commands/cordova-build

Ionic HTTP posts don’t work on iOS

I ran into this strange problem today where HTTP requests stopped working on iOS alone. Even though I have the latest Ionic CLI, my project was running Ionic 1 still.

To solve this http error I removed this plugin:

ionic cordova plugin remove cordova-plugin-ionic-webview

And added this to config.xml:

<access origin="*" />
<allow-intent href="http://*/*" />
<allow-intent href="https://*/*" />
<allow-intent href="tel:*" />
<allow-intent href="sms:*" />
<allow-intent href="mailto:*" />
<allow-intent href="geo:*" />

Probably a bit unsafe to allow everything but had to get it working again.
If this doesn’t work for you try to also remove the iOS platform and re-add it.

good luck~

How to Hide Specific Ionic Tabs in Angular

How to Hide Specific Ionic Tabs in Angular? It turns out ionic does not support this functionality by default although I think it should, but luckily it’s not that complicated.

Here are the 3 simple steps:

1. In your tabs.html add this ng-class

<ion-tabs ng-class="{'tabs-item-hide': hideTabs}">

</ion-tabs>

2. Add ‘hide-tabs’ in your views where you want to hide the tabs

<ion-view hide-tabs> 

</ion-view>

3. In your app.js add the directive to hide tabs

.directive('hideTabs', function($rootScope) {
    return {
        restrict: 'A',
        link: function($scope, $el) {
            $rootScope.hideTabs = true;
            $scope.$on('$destroy', function() {
                $rootScope.hideTabs = false;
            });
        }
    };
})

The hide-tabs directive will hide the tab on whichever ion-view you set it to.

How to Format Post Dates to show Time since Post

Ever wonder how to format your post times to show up like Twitter or Facebook time since post in minutes, hours, etc? Here is an example of a facebook post 5 hrs ago:

hours ago

I recently had to do this for one of my Ionic mobile apps. Here is the function in JavaScript:

function formatTimeSincePost(time) { // SHOW TIME SINCE POST

    var now = new Date();
    var postTime = new Date(Date.parse(time));
    postTime = now.getTime() – postTime.getTime();

    var timeAgo = Math.ceil(postTime/1000/60);
    var displayTime = "" ;

    if ( timeAgo > 1440 ){ // SHOW DAYS
        displayTime = "" + Math.ceil(timeAgo/60/24) + " days" ;
    }
    else if (timeAgo > 59){ // SHOW HOURS
        displayTime = "" + Math.ceil(timeAgo/60) + " hrs" ;
    }
    else { // SHOW MINUTES
        displayTime = timeAgo + " min" ;
    } 

  return displayTime;
}

You can also add months and years easily if you wish. There you go, happy coding.
