Crosswalk - An HTML5 compatible WebView replacement for Android based on Chromium

In a nutshell, the Crosswalk project provides a generic WebWiew with the latest HTML5 feature support. It is based on the Chromium project.

Enable the most advanced web innovations with the Crosswalk Project web runtime to develop powerful Android and Cordova apps.

Problems addressed by Crosswalk
With the platform variations in the market you are forced to assume that every Android WebView works differently. There are differences in:

Which JavaScript APIs are available
Support and syntax for CSS properties
How your application's interface is rendered
…and plenty more. You want to support as many versions of Android as possible, but it’s frustrating and time consuming.

Advantages using Crosswalk

Get consistent, predictable behavior by reducing Android device fragmentation.
Use the latest web innovations and APIs. Provide a feature rich experience on all Android 4.0+ devices.
Easily debug with Chrome DevTools.
Improve the performance of your HTML, CSS, and JavaScript.

Pattern: Riblets vs. VIPER

Engineering the architecture behind Uber's new rider app

Not being held back by our extensive codebase and previous design choices gave us the freedom where we otherwise would have made compromises. The outcome is the sleek new app you see today, which implements a new mobile architecture across both iOS and Android. Read on to learn why we felt the need to create this new architecture pattern, called Riblets, and how it helps us reach our goals.

The platforms share:

Core architectureClass namesInheritance relationships between business logic unitsHow business logic is dividedPlugin points (names, existence, structure, etc.)Reactive programming chainsUnified platform components
Each Riblet is made up of one Router, Interactor, and Builder with its Component (hence the name), and optional Presenters and Views. The Router and Interactor handle the business logic, while the Presenter and View handle the view logic.

How to link to TestFlight App in iOS

There are two things you need to do. First, check to see if TestFlight is installed. Then create a new link to your app.

NSURL *customAppURL = [NSURL URLWithString:@"itms-beta://"];
if ([[UIApplication sharedApplication] canOpenURL:customAppURL]) {

// TestFlight is installed

// Special link that includes the app's Apple ID
customAppURL = [NSURL URLWithString:@"https://beta.itunes.apple.com/v1/app/978489855"];
[[UIApplication sharedApplication] openURL:customAppURL];
}

This special https://beta.itunes.apple.com URL will be opened directly in TestFlight.

Finally, if you are using iOS 9 (or later), you need to make an addition to your Info.plist to get the canOpenURL: method to work.

If your app is linked on or after iOS 9.0, you must declare the URL schemes you want to pass to this method. Do this by using the LSApplicationQueriesSchemes array in your Xcode project’s Info.plist file. For each URL scheme you want your app to use with this method, add it …

Implementing UI tests on iOS and Android using screenshot comparison tools

Have you ever thought when writing or maintaining UI tests, there must be a better way?

Take a look at screenshot tests provided by Google Firebase and Facebook:

ios-snapshot-test-case
A "snapshot test case" takes a configured UIView or CALayer and uses the renderInContext: method to get an image snapshot of its contents. It compares this snapshot to a "reference image" stored in your source code repository and fails the test if the two images don't match.

screenshot-tests-for-android
Testing rendering for your Android app is hard. How do you prevent visual regressions in paddings and margins and colors from creeping in?
Iterating on UI code is hard. How do you quickly verify that your layout or view changes work correctly in all configurations?

screenshot-tests-for-android can solve these problems by providing a test framework that checks for visual differences across changes.

iOS 7 Blur Effect

Combining a strong colour with a blurred and translucent UINavigationBar in iOS 7.

// cheers to @stroughtonsmith for helping out with this one
UIColor *barColour = [UIColor colorWithRed:0.13f green:0.14f blue:0.15f alpha:1.00f];

UIView *colourView = [[UIView alloc] initWithFrame:CGRectMake(0.f, -20.f, 320.f, 64.f)];
colourView.opaque = NO;
colourView.alpha = .7f;
colourView.backgroundColor = barColour;

self.navigationBar.barTintColor = barColour;

[self.navigationBar.layer insertSublayer:colourView.layer atIndex:1];

And also
myView.backgroundColor = [UIColor clearColor];
UIToolbar* bgToolbar = [[UIToolbar alloc] initWithFrame:myView.frame];
bgToolbar.barStyle = UIBarStyleDefault;
[myView.superview insertSubview:bgToolbar belowSubview:myView];

Why bother replicating the effect? Just draw a UIToolbar behind your view.

iOS: LLVM based mutation testing to check your unit test reliability, Android and Kotlin: JVM based mutation testing

LLVM-BASED MUTATION TESTING SYSTEM

Several years ago I discovered very powerful technique - Mutation Testing. Since then I was (and still am) dreaming to have a tool which will do the job for languages like C, Objective-C and C++.

Now I have confidence in that it can be implemented using LLVM.

Outline for this article:

JVM-BASED MUTATION TESTING

PIT is a state of the art mutation testing system, providing gold standard test coverage for Java and the jvm. It's fast, scalable and integrates with modern test and build tooling.

Apps vs. Web

Eines scheint klar: Mobil büßt er gegenüber den Softwareprogrammen aus dem App-Store Nutzer ein. „Mittlerweile spielen Apps die wichtigste Rolle für den User – oder sie werden sie zumindest sehr bald spielen“, sagt Jan Wolter, Geschäftsführer von Applause EU.

Apps bieten also im Gegensatz zum Browser Schnelligkeit gepaart mit Einfachheit und Bequemlichkeit. Sie öffnen zwar nicht die Welt ins gesamte World Wide Web, wie es der Browser kann, aber sie öffnen die Welt, die man möchte, wenn man ihr Icon auf dem Tablet anklickt.

Die chinesische App WeChat geht noch weiter: Neben einem Messenger, vergleichbar mit WhatsApp, bietet sie einen Lieferdienst à la Lieferando, die Möglichkeit etwa das eigene Konto zu checken (wie sonst bei der Bank-App) und gleichzeitig die Chance etwa Promis zu folgen, wie es Twitter bietet.

Solche Alpha-Apps können dadurch verschiedene Aspekte und Möglichkeiten des Internets verbinden und werden so zum idealen Zugangsportal zum Netz – so wie traditionell der Brows…

Alpha Apps vs. App Unbundling

Aktuell wird viel über das Modell der "Alpha Apps" und "App Unbundling" gesprochen.
Hier kurz eine Übersicht und meine 5 cents:
Alpha Apps

Solche Alpha-Apps können dadurch verschiedene Aspekte und Möglichkeiten des Internets verbinden und werden so zum idealen Zugangsportal zum Netz – so wie traditionell der Browser am Computer. Den Tod des Browsers bedeutet das aber noch lange nicht.

Der Browser ist tot, es lebe der Browser!

Aber nicht jede Unbundling Aktion wird positiv von Usern aufgenommen. Facebook Messenger erhielt hunderte mi…
