Question

I’m new in Android and even Java.
I have to save and read message in an activity using another class “Utility”. And it will cause ANR, I heard I have to do that kind of things in a separate thread.
this is my code:

Utility.save(this, message, lsn);
Message tmp = Utility.read(this, lsn);

and I tried this:

final ProgressDialog progressDialog = ProgressDialog.show(
        this, "Please wait....", "Here your message");
new Thread(new Runnable() {
    public void run() {
    Utility.save(this, message, lsn);
    Message tmp = Utility.read(this, lsn);
        progressDialog.dismiss();
    }
}).start();

and as you can imagine, there is no way go just like this.
Do I need to use aidl?

Thank you guys.

what you should probably do is use AsyncTask which is the Android way of multi threading in apps.
