Check if there is errors after some asynctask

Question

I have 2 main AsyncTask which goal is to syncronize my app.

uploadFile and SyncData

So, if I have 3 pic to upload, I will have 3+1 = 4 threads

Each process fill a global error variable. So what I need is to get a way to run this method after all threads are done. How can I do it???

 for (Captura capt : lCapturassASync) {
        uploadFile(capt, ctx); // Is also an AsyncTask
    }
    new SyncData(ctx, lTiendasASync, lCapturassASync).execute("upload_datos", null);
