Using a Debugger The debugger keyword can be used to debug your application.When most browsers encounters a `debugger` statement, execution of Javascript is stopped, and your browser will load its debugger.This can be used to set "breakpoints" in your application.For example, if you write a function that is not returning what you expect it to, you can add a debugger statement to the first line of the function: { ; } When your application runs, it will pause at this function.From there, you can use your browser's developer tools to only execute Javascript step-by-step.This allows you to see exactly which line or function call is causing your function to break.Changing the Platform By default, when you view your app in the browser, Ionic will apply the iOS theme.However, since Ionic components adapt according to their platform, it is helpful to be able to view what your app looks like on Android.To do this, simply add ?ionicplatform=android to the URL where your app is being served: http://localhost:8100/?ionicplatform=android.

This will change how Ionic sees which platform you are on.However, this will not change how the browser sees which platform you are on.To change how the browser sees which platform and device you are on, you must change the user-agent.To do this, open up Chrome DevTools, and toggle device mode on with Ctrl + Shift + M (Cmd + Shift + M on Mac).Selecting devices from the device dropdown will change the user-agent, as well as the dimensions of the viewport.Between this and adding the ?ionicplatform=android URL param, you can check out how your app will look on a wide number of devices.an und verkauf von möbel oldenburgUsing the iOS Simulator The iOS simulator allows you to test and debug your app before running it on an actual device.möbel geschäft münsterBefore it can be used, we need to install Xcode, Apple's IDE.gebrauchte möbel in hamburg zu verschenken

The Ionic CLI can then be used to run the app in the current directory on the simulator: ionic cordova emulate ios -lc Passing in the -lc flag will enable livereload and log console output to your terminal.You can also use Xcode to launch the emulator and debug your app.Open up Xcode and open ../path-to-app/platforms/ios/myApp.xcodeproj.After your app loads, you will be able to run it and see all console output inside of Xcode's output window.Using the Genymotion Android Emulator While the Android SDK comes with a stock emulator, it can be very slow and unresponsive at times.gebrauchte mobel verkaufen in paderbornGenymotion is an alternate emulator that is blazing fast, and allows you to emulate native functionality like GPS and camera.mobel gebraucht in rostockRemote Debugging - iOS and Safari Safari can be used to debug an Ionic app on a connected iOS device.mobel muri bern

First, we need to enable Web Inspector on the connected device.Web Inspector can be found under Settings > Safari > Advanced.Next, head over to the Safari on your Mac and enable Show Develop menu in menu bar under Safari > Preferences > Advanced.The connected device should now appear in the Develop menu.From there, you can inspect it and use Safari's developer tools to debug your application!Remote Debugging - Android and Chrome Chrome DevTools are a very powerful set of tools for debugging your application.möbel kaufen lübeckWhen you use ionic serve to run your application in the browser, DevTools can be used to inspect elements, view console logs, profile your application, and much more.lounge gartenmöbel preiswertIn addition to using DevTools to debug your app in the browser, DevTools can be used to debug a remote physical Android device, or even a Genymotion emulator running your app.möbel billig kaufen münchen

First off, we will need to have adb installed.Once installed, if your device is connected, or an Android emulator is running, you should be able to see your device listed when you run the following command: adb devices Next, go to chrome://inspect/#devices in Chrome and inspect your Android device.Note: you may need to change the settings on your device to allow USB debugging.From there, you can use Chrome to debug your application just like it is in the browser!Remote Debugging - VS Code Plugin VS Code has a dedicated plugin for debugging apps built with Cordova.The plugin creates bridge between the device and the debugger and allows you to set break points in your editor directly.Mobile emulators are undoubtedly a useful tool for all web designers and developers.The ability to test web content in a multitude of configurations in a cost effective manner cannot be overlooked.Thankfully this functionality is often included within modern browsers.Whilst there are positive aspects to emulation web professionals must be careful not to become reliant on this method as there are also several limitations, which if not considered can impact a great user experience.

The benefits of mobile emulation You don't need to be a seasoned IT professional to use the tools provided within browsers You don't need access to 100's of real devices which otherwise could take valuable resources Data and reports can be extracted or refreshed in real time Emulation is better than adjusting browser windows to shrink display - Differences between competing browsers make this a poor option.You can emulate typical network technologies such as 3G or Edge - This comes in handy if you want to see how your page responds under varied speeds.How to perform simple emulation Modern browsers include a built in emulator to help test a webpage from a mobile vantage point.It's worth mentioning that Firefox does not ship with this feature but it can be added via a plug-in.You can find our own guide on testing your website for mobile performance here.For more browser specific information please click the images below.The limitations of mobile emulation You're not able to test a real time connection with an emulator - If your website loads slowly no amount of beautiful design will compensate your aggrieved customers.

Not being able to see real dimensions or use native touchscreen and QWERTY navigation invalidates user experience testing - Customers won't use an emulator to access your mobile website.Competing browsers use different rendering engines which parse content using different techniques - One browser may not reflect mark up content correctly across platforms Common rendering engines include Blink, which is used by Chrome and Opera.Trident, which is used by Internet Explorer and Gecko, which can be found in Firefox.The Blink engine is a newer fork of the WebKit engine which Safari continues to use today.At the very least this means you'll need to perform testing over several emulators to ensure layout of your webpages remains consistent and error free across engines.Naturally this eats away at the efficiency gained from utilising simple emulation.The options for mobile emulation As software is difficult to program to capture the nuance of human behaviour the ideal solution is a combination of methods to ensure aspects are considered from multiple perspectives.

Testing is an essential part of your development cycle and whether you use Device Detection or Responsive Web Design (RWD) emulators are one tool among many to provide your customers the best possible user experience.Responsive Web Designers often bemoan the testing process as mark-up content is governed by a static set of rules.If a rendering engine update changes the way it handles content then changes must be made to reflect this in order to avoid rendering issues.If a new configuration needs to be catered for then developers must update rules and perform testing again.For example; a new iPhone model will require regression testing on Internet Explorer to ensure compatibility.Expectedly this means RWD requires a lot of maintenance and testing to keep up with permutations of new technologies or devices.A Device Detection Repository (DDR) can help to take the sting out of testing as logic provided is dynamic and explicitly relates to the configuration accessing your website in real time.

This makes them very lightweight and only requires that your templates are retested with an engine update.51Degrees works with device vendors to ensure our device profiles contain the most accurate and up to date information to aid both your testing and real time device detection.There are essentially two levels of emulation, the simplest form is from within a browser.A more advanced technique can be obtained with the use of a Software Development Kit (SDK).A SDK provides an accurate facsimile of the mobile operating system and it should be thought of as a preliminary testing tool to use before testing on an actual device.Links to SDK's for the major mobile operating systems can be found in the emulators section at the bottom of this page.The solution to mobile emulation As emulation software only provides an approximation of the device there are occasionally discrepancies when using some emulators in conjunction with a good device detection provider.In these cases the device detection accuracy can catch that it is an emulator accessing a website rather than a real device and may return values that were unexpected.

For example if you use Chrome to emulate a Samsung Galaxy S5 accessing a website with device detection while using desktop compatibility mode then it may not be detected as a mobile or tablet device; as per the users request to appear in a desktop guise - It is important for developers to be aware of this during testing.For effective testing you should incorporate both simple browser emulation to rapidly eliminate major issues and SDK simulation to identify any further issues.Finally you should also perform live testing to help ensure that your testing procedures are sound and complimentary.By utilising a tiered testing approach as shown in the mobile testing pyramid you can catch issues that may not be apparent with a restricted test environment.Sometimes however, software emulators just aren't good enough to ensure a great user experience.No official emulator is available, and whilst MobiOne does a good job it's not the same as the real thing.If you would like to see why some of the worlds leading businesses use 51Degrees, then try our free 30 day trial.
