So What Should I Do @iamwsumit

Phantom · July 20, 2021, 9:09am

i imported into koudlar but empty result

Phantom · July 20, 2021, 9:10am

@iamwsumit What Should I Do Know

iamwsumit · July 20, 2021, 9:17am

You also need to use thread

Phantom · July 20, 2021, 9:23am

i tried but can you show a example i didn’t not understand @Sumit1334

iamwsumit · July 20, 2021, 9:25am

What you have tried in thread? Show me.

Haven’t I already posted?

There are a lot of open source extension. Also web component is Open Source. Why don’t you search a little? Google the thread and you will get your answer.

Just run it on non-ui or other thread!

AsynchUtil.runAsynchronously(new Runnable() {
            @Override
            public void run() {
                // YOUR WORK
            }
        });

new Thread(new Runnable() {
            @Override
            public void run() {
                // YOUR WORK
            }
        }).start();

ExecutorService executorService = Executors.newSingleThreadExecutor();
        executorService.execute(new Runnable() {
            @Override
            public void run() {
                    // YOUR WORK
            }
        });

Anyone of this is okay!

You are just blindly doing things.
Learn the basics.
