This example demonstrates how do I set a Timeout for an AsyncTask in android.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:padding="16dp"
   tools:context=".MainActivity">
   <EditText
      android:layout_marginTop="50dp"
      android:id="@+id/enterTime"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerHorizontal="true"
      android:background="@android:drawable/editbox_background"
      android:inputType="number"/>
   <Button
      android:id="@+id/btnRun"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Run Async task"
      android:layout_below="@+id/enterTime"
      android:layout_centerHorizontal="true" />
</RelativeLayout>
Step 3 − Add the following code to src/MainActivity.java
import androidx.appcompat.app.AppCompatActivity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
   Button button;
   EditText editTextTime;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      button = findViewById(R.id.btnRun);
      editTextTime = findViewById(R.id.enterTime);
      button.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            AsyncTaskRunner runner = new AsyncTaskRunner();
            String sleepTime = editTextTime.getText().toString();
            runner.execute(sleepTime);
         }
      });
   }
   private class AsyncTaskRunner extends AsyncTask<String, String, String> {
      ProgressDialog progressDialog;
      @Override
      protected String doInBackground(String... params) {
         publishProgress("AsyncTask started...");
         String resp;
         try {
            int time = Integer.parseInt(params[0]) * 1000;
            Thread.sleep(time);
            resp = "Slept for " + params[0] + " seconds";
         }
         catch (Exception e) {
            e.printStackTrace();
            resp = e.getMessage();
         }
         return resp;
      }
      @Override
      protected void onPostExecute(String result) {
         progressDialog.dismiss();
         Toast.makeText(MainActivity.this, "AsyncTask Terminated", Toast.LENGTH_SHORT).show();
      }
      @Override
      protected void onPreExecute() {
         progressDialog = ProgressDialog.show(MainActivity.this, "ProgressDialog", "Wait for " + editTextTime.getText().toString() + " seconds");
      }
      @Override
      protected void onProgressUpdate(String... text) {
         Toast.makeText(MainActivity.this, "" + text[0], Toast.LENGTH_SHORT).show();
      }
   }
}
Step 4 − Add the following code to androidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.sample">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>
