How can you pass multiple primitive parameters to AsyncTask?

by

Just wrap your primitives in a simple container and pass that as a parameter to AsyncTask, like this:

private static class MyTaskParams {
    int foo;
    long bar;
    double arple;

    MyTaskParams(int foo, long bar, double arple) {
        this.foo = foo;
        this.bar = bar;
        this.arple = arple;
    }
}

private class MyTask extends AsyncTask<MyTaskParams, Void, Void> {
    @Override
    protected void doInBackground(MyTaskParams... params) {
        int foo = params[0].foo;
        long bar = params[0].bar;
        double arple = params[0].arple;
        ...
    }
}

Call it like this:

MyTaskParams params = new MyTaskParams(foo, bar, arple);
MyTask myTask = new MyTask();
myTask.execute(params);
