API.AI: How to stop AsyncTask on click of the AIButton?

Question

I’m using AIButton in my app and I have a AsyncTask which gets executed after AIButton is clicked and receives some command and AsyncTask sometimes

Answer 1

Use boolean cancel (boolean mayInterruptIfRunning).

Make the asyncTask a class variable.

AsyncTask translate_ = new translate();

Then call it like so in place.

translate_.execute(textToTranslate.getText().toString(), "az");

Within the button onclick cancel the asyncTask.

translate_.cancel(true);

Then check within your loop that the task has been cancelled and set a break.

for (int i=0; i

It would be wise to manage the task on backpress also. Perhaps cancel the task in the activity onpause.

public void listenButtonOnClick(final View view) {
    // aiService.startListening();
    // add more details in here

    if (aiService != null) {
        switch (currentState) {
            case normal:
                aiService.startListening();
                break;
            case busy:
                aiService.cancel();
                translate_.cancel(true);
                break;
            default:
                aiService.stopListening();
                translate_.cancel(true);
                break;
}

Or cancel the task when the aiservice is cancelled or stopped.

@Override
public void onListeningStarted() {}

@Override
public void onListeningCanceled() {
    translate_.cancel(true);
}

@Override
public void onListeningFinished() {
    translate_.cancel(true);
}

There's other ways it can be managed, explore your options. Have a good look at this and the SO questions linked above.

If you have a look at the docs.

apiai-android-client/ailib/src/main/java/ai/api/ui/AIButton.java

@Override
protected void onClick(final View v) {
    super.onClick(v);

    if (aiService != null) {
        switch (currentState) {
            case normal:
                aiService.startListening();
                break;
            case busy:
                aiService.cancel();
                break;
            default:
                aiService.stopListening();
                break;
        }
    }

}

Go back to the basics. Forget about the ai.api for a while and learn the basics. Browse around, read the docs Input Events read questions and apply the programming principles. For example:
