Here is the working solution (if your activity is not running it will disable itself)

<pre><code>@Override
protected void onServiceConnected() {
 super.onServiceConnected();
 Toast.makeText(this, "Connected!",Toast.LENGTH_SHORT).show();
 ScheduledExecutorService scheduleTaskExecutor = Executors.newScheduledThreadPool(1);
 scheduleTaskExecutor.scheduleAtFixedRate(new Runnable() {
 public void run() {
 serviceChecker();
 }
 }, 0, 5, TimeUnit.SECONDS);
}

private void serviceChecker(){
 if(!isActivityRunning(MainActivity.class)) {
 if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.N) {
 disableSelf();
 }
 }
}
protected Boolean isActivityRunning(Class activityClass)
{
 ActivityManager activityManager = (ActivityManager) getBaseContext().getSystemService(Context.ACTIVITY_SERVICE);
 List&lt;ActivityManager.RunningTaskInfo&gt; tasks = activityManager.getRunningTasks(Integer.MAX_VALUE);

 for (ActivityManager.RunningTaskInfo task : tasks) {
 if (activityClass.getCanonicalName().equalsIgnoreCase(task.baseActivity.getClassName()))
 return true;
 }

 return false;
}

The top answer talks about PackageManager, which tells you what is running.

I would like to programmatically enable/disable Accessibility Services listed under Settings->Accessibility option.

I could start Accessibility Intent like below:

<pre><code>Intent intent = new Intent(android.provider.Settings.ACTION_ACCESSIBILITY_SETTINGS);
startActivityForResult(intent, 0);
</code></pre>

But I don't have any idea on how to enable the services listed in the view through my code.

Please, provide me your views.
