Description

itstimetoact - it's an android library, inspired by once, that can help you with planning events in your awesome application. It requires api level >= 1, so can be used in any project.

Structure

As it's a very lightweight library, the core module hasn't anything except the base classes, but there is several additional modules with some tasty implementations included. Moreover, if you feel the lack of it, then flexible, awesome, simple and documentated API will help you with creating your own! For now the following modules are available:

• itstimetoact-core - provides several base classes. Actually you may use only this module if you are going to implement all of your events and serialization/deserialization mechanism by yourself.
• itstimetoact-serializable - implementation that uses java.io serializables to serialize/deserialize events. The main pros of this module that it hasn't any external dependencies (unlike the next one).
• itstimetoact-gson - another one implementation that uses gson library to serialize/deserialize events. It is preferable to use this one over of previous one (especially if you already use gson in your project or if you are using your own event implementations).
• itstimetoact-extras - the set of some useful event implementations, that, I hope, will satisfy most of your needs.

Usage

It will be great start to check the itstimetoact-sample module. If you too lazy for it, read the stuff below.

Initializing

Okay, let's start. Initially, you need to create TimeToAct instance. It can be performed in Application#onCreate or in Activity#onCreate(Bundle). Anyway, it fits great with something like dagger, so there is no much difference.

TimeToAct timeToActInstance = new GsonTimeToAct(this); // or SerializableTimeToAct

Restoring previous state

The next thing which you need to do is restore previous state. Even if it's a first run ever, you need to call this method:

timeToActInstance.loadEventData();

Keep in mind, that this method isn't async, so can stuck your UI-thread.

Action

Now you can write your code. Imagine, that all of next stuff were written in Activity#onCreate(Bundle).

For example, the following code will be executed after each application update:

ActEvent afterUpdateEvent = timeToActInstance.watchEvent(new AfterUpdateEvent(this, "key0"));
if(afterUpdateEvent.isHappened()) {
    // ...
    // show changelog or something like that
    // ...
    timeToActInstance.watchLastDropped("key0");
}

The following code will be executed after five days:

ActEvent timeEvent = timeToActInstance.watchEvent(new TimeEvent(TimeUnit.DAYS.toMillis(5), "key1"));
if(timeEvent.isHappened()) {
    // ...
    // show 'rate me' dialog
    // ...
}

Next one will be executed only once per install:

OneShotEvent oneShotEvent = timeToActInstance.watchEvent(new OneShotEvent("key2"));
if(!oneShotEvent.isHappened()) {
    // ...
    // show application tutorial
    // ...
    oneShotEvent.step();
}

You also can combine they together to describe more difficult situations. And as I said above, there is a flexible API, so you can implement your own awesome 'is happened' logic!

Now imagine the following situation. You have 'rate me' dialog (that must appears after two days since install) with three buttons: "Don't show again", "Reming me later", "Rate now". With the library it can be implemented like this (example from real application):

OneShotEvent neverShowClicked = timeToActInstance.watchEvent(new OneShotEvent(KEY_SHOW_RATE_ME));
TimeEvent cycle = timeToActInstance.watchEvent(new TimeEvent(TimeUnit.DAYS.toMillis(2), KEY_SHOW_RATE_ME_CYCLE));
if(!neverShowClicked.isHappened() && cycle.isHappened()) {
    // ...
    // some dialog creation logic
    // ...
    dialog.show(new DialogListener() {
        @Override
        protected void onViewCreated(View view) {
            applyListener(view, R.id.rate_no, this::dontShowAgain);
            applyListener(view, R.id.rate_later, () -> timeToActInstance.watchLastDropped(KEY_SHOW_RATE_ME_CYCLE));
            applyListener(view, R.id.rate_yes, () -> {
                openMarketPage();
                dontShowAgain();
            });
        }

        private void dontShowAgain() {
            neverShowClicked.step();
        }
    });
}
