How to Run my app in background.

[Ajay]

Hi Team,
    I want to update location information every 'n' minutes, so have set the time interval to execute the function after 'n' minutes.
it works fine if the app is in active state,if the app is in background its not working.
have used power management plugin also,it makes the device awake only if am running my app, if i switch to other apps it no longer works.


Thanks in advance.

Hello Anup,

We've already discussed with you a possible solution how to achieve such functionality in this forum thread. The PowerManagement plugin is 3rd party software and we have not invested much time testing it, but we see that there is a newer version since we initially suggested using it. Please upgrade the plugin to the latest version and see if that makes a difference.

If the problem persists and you believe this is a problem with the plugin functionality, please contact the author directly in the plugin repository.

Hello Steve,
Thanks for the reply.
 yes i have updated PowerManagement plugin. but  PowerManagement only avoids device from going to sleep mode .
If user press home button, application will go to background and stops running javascript. My requirement is to get the location information even if the app is in background  or device in sleep mode. how do i achieve this.

Thanks

Hi Anup,

Did you figure out how to get it to run in the background the entire time and still run the code to update the gps?

Thanks,
Warren

Isn't a running background app a 'service' by definition?

Hello Sulu,

The terminology as well as the approach for running background tasks really depends on the OS specifics. In Android in order to perform a ling running task in the background, you need to create a service. However, in the context of iOS a long running task can be implemented in the background by an app running in the background but only in case that this app meets the requirements for running without being suspended.

Hello,

We don't have a sample project demonstrating how to use the PowerManagement  plugin you mentioned. However, in order to integrate it in an AppBuilder project, you can download it as a zip from its repository and then follow the steps outlined in the Import Custom Plugins tutorial.

Once imported, the plugin allows you to invoke the following methods:

• powerManagement.acquire(onSuccess, onError,runLockScreen); -  acquire a new wake-lock to keep device awake
• powerManagement.release(onSuccess, onError); - release the wake-lock
• powerManagement.dim(onSuccess, onError); - acquire a partial wake-lock, allowing the device to dim the screen

If you need any further information on how these methods work on each device, you can follow the links provided by the plugin author in its repository:

• for Android: PowerManager
• for iOS: idleTimerDisabled
• for WindowsPhone: UserIdleDetectionMode

If you encounter any issues with the plugin, I would also recommend that you share them with the plugin authors as they might be able to better assist you in resolving them.

I have the same problem, my application has a function in js that if the application is closed function stops working and that is not feasible; therefore we need a plugin that poueda leave the application in the background

Hello Javier,

A possible solution is to use the Cordova Background mode plugin. This plugin prevents the application from going to sleep while in the background. More information on how to use the plugin is available here.

Additionally, I was able to successfully include, deploy and use the above plugin in an AppBuilder Cordova project. I am attaching the sample project to this message for your reference.

I hope this helps.

Hi preslav's,

Thanks for your post, Give code Blank3(BackGround Service) its only working on inside the app. When Exit its not working why?

[Preslav]

Hi Raj,

From your second post, I understand that you have already managed to fix the error from the first one. Is that correct?

The application is not supposed to work when the user force closes it, for example, by swiping it up on an iPhone. It should be working when the app is still running in the background.

Good afternoon computer, I in android found the solution and has nothing to do with the telerik platform; Relatively this is focused on the use of plugin and handling of these for because I modify one that puts the application in the background .. but one thing is to be in the background and another that the functions in javascript are executed in time and form being in the background ; To obtain a more accurate solution modify a plugin that creates a service in to perform tasks in the background having as parameter date of realization; For example can be my application in the background and run ajax data send to web service / database every 10/15 minutes
