As I see there are two independent methods, so there's no problem in parallelizing them. You could launch an executor service to do that and then await for termination:

@Override 
protected Integer doInBackground(Void... params) {
    Integer result = null;
    try{
        ExecutorService executor = Executors.newFixedThreadPool(2);
        Runnable thread1 = new Runnable() {
            @Override
            public void run() {
                try {
                    method1(_phoneno);
                } catch (Exception ex) {
                    throw new RuntimeException(ex);
                }
            }
        };
        executor.submit(thread1);
        Runnable thread2 = new Runnable() {
            @Override
            public void run() {
                try {
                    result = method2(_phoneno,_ticket);
                } catch (Exception ex) {
                    throw new RuntimeException(ex);
                }
            }
        };
        executor.submit(thread2);
        executor.shutdown();
        //Timeout for both tasks = 120 seconds
        if (!executor.awaitTermination(120, TimeUnit.SECONDS)){
            throw new RuntimeException("Could not complete requests in the given time!");
        }
        return result;
    }catch(Exception ex){
        //Keep your exception to be shown in a toast
        exception = ex;
    }
}
