It works fine if the app goes to the foreground but as soon as I close the application the task I am running stops as well. What am I trying to do in background is to write my own implementation of significant location-change service since there is no free plugin for Cordova or PhoneGap that can work with both iOS and Android.
Optimize Ionic 2 App for Production
I've recently implemented a feature like this in my project. I did use Ionic and I did use the Cordova plugin background mode from Katzer. I think the background geolocation tracking that you're trying to implement already exists as a cordova plugin, it's called cordova-plugin-mauronbackground-geolocation.
This plugin is both a foreground and background geolocation service. It is far more battery and data efficient then html5 geolocation or cordova-geolocation plugin. Learn more.

Did you get any solution? Active Oldest Votes. Ionic Framework I've recently implemented a feature like this in my project. And that works even if you completely close the app? If you close the app as in "move it to background" it will work. What if the person turns off the phone I mean a complete shutdown and restartthen what would it it take to put your code back into the game?
I know that all Alarm apps achieve that. AverageJoe I think that's nearly impossible or you need to write values to memory that's kept after restarting or another data source like a NoSQL database. Since alarm apps can do that, I suspect that there must be a way.
I just tried this on my android phone; 1 set up an alarm 3 min for later. At that time, the alarm app was not among the "running apps" but the alarm itself was able to fire.
There are a lot of configuration options, see the github page linked above. Does this work, if your app is closed and NOT running in background?! Rebar Background activity will happen only when the app is in the background. Above code won't support on a killed app or NOT running in the background. But that's not good! The Overflow Blog.

Dark Mode Beta - help us root out low-contrast and un-converted bits.Developers in all industries are rapidly discovering the benefits of using Ionic's front-end framework for developing hybrid mobile apps, but for ecommerce companies, speeding app development becomes mission-critical for building loyalty, differentiating websites and staying competitive.
The Ionic platform, which uses Angular JS to build frameworks that host robust functions, makes it easy to utilize libraries of code-sharing resources and build high-performance cross-platform applications.
Some developers, however, worry about using open source materials for proprietary commercial apps -- especially those frameworks that use browsers to run cross-platform apps -- because of time lags, stutters, slower scrolling and other performance issues.
Ionic provides essential tools, services, preprocessors for sharing code and other options for optimizing performance, and the advantages of getting new apps into the stores faster outweighs most remaining performance shortcomings.
Essentially using native wrapping and functionality for browser-powered applications, Ionic and Cordova accelerates development. It's just up to each developer to choose the wrapping components, compression strategy, preprocessing tools and other enhancements to balance app performance with speed-to-market issues. During the development process, programmers can take advantage of shortcuts, preprocessors like Sass, uglification and other strategies to enhance performance in multiple areas.
It's important to test each app on various devices before releasing it to the Google Play or Apple App stores, and it makes sense to conduct the tests on various devices and networks to understand what kind of experience customers will have when using different connections and equipment. Getting things as tight and accurate as possible is essential for getting high ratings at the stores, but developer efforts don't need to stop after launching an app.
Building the most useful apps for ecommerce customers is a collaborative effort, and savvy companies take note of customer reviews, ratings, comments and suggestions for improving app performance in upgrades and new iterations. The best strategy is not to restrict users from sharing information socially because sharing can create buzz for an app, engage customers and strengthen loyalty when the app is updated.
New iterations can fix old problems, and mobile Darwinism favors apps that can evolve. The following areas are important issues that developers can fix pre- or post-launch to enhance app performance:.
Emulators just don't work because they tend to be slower than testing on actual units, although recently, they've become better at true performance emulation. It's also important to remember that numerous customers use various devices and networks at the same time, so load testing is important for testing the performance issues of different customer profiles.
The key to increasing app speed is to remove unnecessary characters, compress files, use third-party delivery services and access parts of images like logos for multiple purposes.
Developers can search for technical coding tips to reduce code and reuse code in multiple ways to speed app performance. Simple designs and architecture not only enhance app performance but also makes apps easier to use. Since hybrid apps are already hosted on browsers and connected to the Internet, there's no reason not to take advantage of external resources, but keep in mind that customers might not have fast Internet service.
What appears blazing fast on a business network might look like a slide show to some customers. Avoid using too many external resources, and never use more pages, tabs and page elements than necessary. Third-party plugins comprise one of the major advantages of using Cordova's open source platform when developing apps.
Developers can search for plugins for extra functionality, device-specific capabilities, native sharing and cross-platform support for Battery, Dialogs, Camera, Geolocation, and other key functions.Free and open source, Ionic offers a library of mobile-optimized UI components, gestures, and tools for building fast, highly interactive apps.
Start with ready-made components, typography, and a gorgeous base theme that adapts to each platform. Ionic enables web developers to ship apps to the app stores and as a PWA with a single shared code base. Create, build, test, and deploy your app with a powerful CLI.
Access features like Live Reload, cross-platform deployments, and integrations. Ionic is built to perform and run fast on the all of the latest mobile devices.

Viewed 40k times. Sampath A pause eventlistener will tell you when the user closes the app. The resume eventlistener will do the opposite of that.How healthy are you quiz for students
The Resume and Pause events will be fired independently from a variable or sth like this. They will be fired if the user presses the home button, or if the user resumes the application. Sithys - simply listening for fired events doesn't answer the question that user asked "Is there any way to check whether the app is running in foreground or background" Active Oldest Votes. Event - Pause: The pause event fires when the native platform puts the application into the background, typically when the user switches to a different application.
Event - Resume The resume event fires when the native platform pulls the application out from the background. You can add an Eventlistener for that into your code. For those two Events that would be: Pause - Quick Example document. Sithys Sithys 3, 4 4 gold badges 24 24 silver badges 48 48 bronze badges.
My app was supposed to detect this event on another page in the app and during that time, my app could be at the background. How can I achieve this? I need to know if the app has been launched in background like after a VoIP push.

Once the app is paused I don't believe it will continue to execute any code.So before you build the final production ready version of your Ionic application, you might want to first minify it.
Minifying code is essentially the process of stripping away everything unnecessary : everything is condensed onto a single line, files are concatenated together, variables are renamed to be shorter and so on. A lot of this is based off of [this tutorial] by Agustin Haller which was tremendously helpful to me.
We are going to use a few different tools here, but the overall process we are trying to achieve is:. Part of this we will build into Ionic so that the process is executed every time we make a change in the app whilst ionic serve is running and the rest we will achieve with a grunt task.
Before we can get started you will need to install all the Gulp and Grunt tools that we want to use. To do that run the following commands from within your project directory:.
NOTE: By adding —save-dev onto the end this will add the tool as a dependency in your package. This will create a single file called styles. If you open up your built index. After using gulp-angular-templatecache we can no longer refer to our templates like this:.
Instead you will need to modify them so that they only reference the file namelike this:. Now we will be using a file in the root of our project called Gruntfile.
For more background on grunt, take a look at [this post], as we will be building on top of that. You can also just download the entire file in the bonus content box below.How to Minimize YouTube app on Samsung Galaxy J7 Prime - Must Watch
