Now run the app and you will have the following output :.

Also don’t forget to add service in the android Manifest file.

Put the extras i.e seconds in secondsToSleep and start the Service.

Create an Intent and pass it from main activity to the corresponding class.

We pass out the value of the text as long and get the text from the edit text convert it to string and pass to Long.

Intent.putExtra('seconds', secondsToSleep) Intent intent= new Intent(MainActivity.this,Sleeper.class) Long secondsToSleep=Long.parseLong(sleepTime.getText().toString()) Public void startService(View v)ĮditText sleepTime=(EditText)findViewById(R.id.editSeconds)

Now in the MainActivity.Java file write the code on the button click :.

Now give the onClick property of the button a name for example : startService which will be using in the mainactivity.java file on the button click code.

In the activity_main.xml file take a text field and a button.

Now in the Mainactivity.Java the onCreate() method is the same as it is.

Toast.makeText(this,String.format('Slept %d seconds',seconds),Toast.LENGTH_SHORT).show()

onDestroy() method is used to destroy the thread and using a Toast.makeText we display the message.Add onDestroy method after the onHandleIntent method:.millis is the milli seconds that we have declared as :.In try block ,we try to use sleep in a thread ,so Thread.sleep(millis).

Protected void onHandleIntent(Intent intent) onHandleIntent is the handle that handles the intent which is declared to be protected :.Intent Service requires a no_argument constructor whose name is same as the name of the class and pass it upto super.Java extend the class with an IntentService. Now take another java file for example name it as Sleeper.Java.Create a new project, yor MainActivity.java and activity_main.xml file will be generated.

It is an easy demonstration of the concept and all we are doing in this example is making the process sleep for number of seconds as entered by the user. Hello Guys !! In this tutorial we are going to implement Intent Service.
