Note that this will need to be registered ether in your application manifest or via context. Broadcast Receiver. You can please try this code to call the handler every 15 seconds via onResume and stop it when the activity is not visible, via onPause.

The downside of this is that you have to architect polling your data in a different way. However, there are a lot of benefits to the Reactive Programming way:. Please check out RxJava. It has a high learning curve but it will make handling asynchronous calls in Android so much easier and cleaner. Here I used a thread in onCreate an Activity repeatly, timer does not allow everything in some cases Thread is the solution.

The AlarmManager is given a PendingIntent to fire whenever an alarm is scheduled. The first corresponds to the time since system boot and the second to UTC time. Below is a list of the different alarm type variations available. If the device is asleep, it fires when the device is next awake. It wakes up the device if it is asleep. RTC — Fires the pending intent at a specified time. If the device is asleep, it will not be delivered until the next time the device wakes up.

Deciding on the alarm to use depends on the requirements of the task at hand.

Time elapsed is suitable for setting alarms that should fire based on the passage of time, for instance regularly checking a server for changes. If you want to run a task dependent on the current locale, then the real time clock will be more suitable.

Note that elapsed time is usually the better choice. If the user changes their time settings or moves to a new locale, the change might cause some unexpected behaviour in the app.

If you set a specific time for an app to sync with a server, the server could be overwhelmed when all instances of the app hit at the same time. Code for this project can be found at this Git Repo. Create a new Android project. For the view, create two buttons that will start and stop the periodic operations.

Create a class that inherits from BroadcastReceiver.

The Overflow Blog.Kotlin coroutines are still in the experimental phase, but they are quickly becoming one of the most popular features for developers that want to use asynchronous programming methods.

Most mobile apps have to perform long-running or intensive operations — such as network calls or database operations — at some point. At any one time, your app might be playing a video, buffering the next section of video, and monitoring the network for possible interruptions, all while staying responsive to user input. Android executes all its tasks by default on a single main UI thread, one task at a time.

If this thread ever becomes blocked, your application is going to freeze, and may even crash. Creating a thread is also an expensive process. Several solutions aim to simplify multi-threading on Android, such as the RxJava library and AsyncTaskproviding ready-made worker threads. Even with the help of third party libraries and helper classes, multi-threading on Android is still a challenge. Think of coroutines as a lightweight alternative to threads.

You can run thousands of them without any noticeable performance issues. While the above code will run without any issues, spawningthreads will likely result in your application crashing with an OutOfMemory error. Asynchronous code can quickly become complicated, but coroutines let you express the logic of your asynchronous code sequentially.

Simply write your lines of code, one after the other, and the kotlinx-coroutines-core library will figure out the asynchrony for you. Handling asynchronous code execution usually requires some form of callback. As callbacks increase, your code becomes more complex and difficult to read. Coroutines provide much more flexibility than plain reactive programming. Android Studio 3. This checkbox adds basic Kotlin support to your project, but since coroutines are currently stored in a separate kotlin.

While coroutines still have experimental status, using any coroutine-related features will cause the Kotlin compiler to issue a warning. The launch function creates a new coroutine and returns a Job object without an associated result value. Once the asynchronous operation inside async completes, the coroutine is resumed and can continue as normal.

Here, myMethod result is executed with the result of the asynchronous operation the result returned by the block of code inside async without having to implement any callbacks. Coroutines introduce suspension of a coroutine as an alternative to thread blocking.

While a coroutine is suspended, the thread is free to continue doing other things. Every coroutine must have at least one suspending function that you pass to the coroutine builder. In addition to Delaythe kotlinx. If you imagine coroutines as lightweight threads, then the coroutine context is like a collection of thread-local variables.

Calling a method repeatedly for every 1 min

All coroutine builders accept a CoroutineDispatcher parameter, which lets you control the thread a coroutine should use for its execution. You can pass any of the following CoroutineDispatcher implementations to a coroutine builder. The CommonPool context confines the coroutine to a separate thread, which is taken from a pool of shared background threads. To see this in action, remove the CommonPool reference from your app:. The newSingleThreadContext function creates a thread where the coroutine will run:.The LG Esteem release date was October Features and Specs include a 4.

Jeyd02 Android Expert. Rockman Member. He is talking about after you get through the lock screen. My lock screen only stays on for a few seconds on both my tablet and S4. I would like it on for at least 10 seconds or so.

I see no way to adjust the lock screen timer, only the general display timer after you get past the lock screen. Rocketman, I came to this forum because with Lollipop when I pressed the standby button to bring up the login screen security pin if you don't touch a key within 2 secs the screen goes dark again.

I found in another forum that if you turn off Power saving the lock screen timeout is much longer. Mine is now 10 secs. To make the change, Settings, Scroll down to My device, Power saving mode. Turn that off and enjoy more time on your lock screen.

Replies: 5 Views: Insane bird new update. Replies: 10 Views: Deleted User Feb 4, Replies: 0 Views: I want to call some function indefinitely when app is in foreground as well as in background.

I need this because I am developing a reminder app, so it should continuously check for active reminders and notify the user on specified time. For background I tried background fetch but it calls the function on its own time not by specified time.

You should use local notifications for this. Read this. On iOS you can't poll things or run code in the background except in very limited circumstances, and this isn't one of them. So the approach you were looking for just isn't allow. On Android it's allowed, but it's just a bad idea for battery life reasons. You want notifications instead. Actually I am using local notification to remind user about their tasks.

But to trigger that notification I need something to run in background forever, of-course I read in many places that it is bad to call function in background forever, but I wonder for a reminder app it is necessary right or am I missing something? But in my case I want to check active reminders in local db sqlite for every 1 minute and sync with server for every 5 minutes to get latest data.

If I found the way to trigger for every 1 minute I would use counter for 5 minutes sync. Using local notification I could set repeat interval for every 1 minute, but how I would be able to check my local db for active reminder using this? In Android we did this using AlarmManager to trigger the intent service for every 1 minute and it checks our local db for active reminders.

How to achieve this in iOS or what type of background service I can implement other than background fetch? I tried below functions in notification object. What it does actually? I just want to know is it possible to call some function for every x minute using Notification as I did above. I got this idea from below thread.

That's in objective c, I didn't understand much, but just tried. Please someone help me to solve this InvokeOnMainThread has nothing to do with notifications. That method is defined on NSObject the base class for all Objective-C classesand that method is just used to run code on the main thread. It doesn't run the code at an interval. It just runs it once.

The answer given in the StackOverflow post is wrong. When your app goes into the background you have a small amount of time to finish what you're doing, and then your app is just suspended all code stops running.

Timers don't fire, and threads stop making progress. Local notifications don't run code. You can schedule a notification at a certain time to show something to the user, but you can't run code unless your app is already in the foreground.

Call function in background thread indefinitely for every x minute ( foreground & background )

I think you need to step back from the solution you have in mind and look at what your actual use case is. You're making a reminders app, so you need to remind people of things at certain times.

You don't need to run code in the background for that. The notification API lets you schedule an alert at a given time. If someone sets a reminder for 2PM on Tuesday then you can create and schedule an alert notification to appear at 2PM on Tuesday, and the OS will take care of showing that alert at the right time.

There's no need for your app to continuously check what time it is and whether it's Tuesday yet. Your app doesn't even have to be running for these notifications to work. I agree with you that an app, no need to run continuously, in background to get reminders from local db.

As I mentioned, in my earlier comment that, I need to sync with server for every 5 minutes to get latest reminders, because user may set their reminder on desktop and they should get that reminder alert on their phone.Today we will look into Android AsyncTask. We will develop an Android example application that performs an abstract AsyncTask in background.

Android AsyncTask is an abstract class provided by Android which gives us the liberty to perform heavy tasks in the background and keep the UI thread light thus making the application more responsive.

android call method every 10 seconds

Android application runs on a single thread when launched. Due to this single thread model tasks that take longer time to fetch the response can make the application non-responsive. To avoid this we use android AsyncTask to perform the heavy tasks in background on a dedicated thread and passing the results back to the UI thread. Hence use of AsyncTask in android application keeps the UI thread responsive at all times. The time in seconds is passed as a parameter to the class and a ProgressDialog is displayed for the given amount of time.

The images given below are the outputs produced by the project where the time set by the user is 5 seconds.

Dear Sir, I have an unique problem. Now this approach is working if I just watch the data, If I want to interact with the ui it freezes and slows down. Please help if you can. Abhishek, you are not suppose to fetch the data from server using main thread. You must need to use asyntask to fetch data. Your email address will not be published.
