Usage

Kotlin

val trialer = Trialer(this)
trialer.trialEndedListener = object : TrialEndedListener {
	override fun onTrialEnded(validatorClass: ValidatorInterface) {
        Toast.makeText(
            applicationContext, 
            "Trial ended by: " + validatorClass::class.java.simpleName, 
            Toast.LENGTH_LONG
        ).show()
    }
}
trialer.addValidator(InstallDateValidator(10))
trialer.addValidator(StaticDateValidator(someFutureDate))
trialer.addValidator(RunTimesValidator(5))
trialer.addValidator(YourCustomValidator())
trialer.addAction(DisplayToastAction(context, "Toast by DisplayToastAction"))
trialer.valid()

Java

Trialer trialer = new Trialer(this);
trialer.setTrialEndedListener(validatorClass ->
    Toast.makeText(
        getApplicationContext(),
        "Trial ended by: " + validatorClass.getClass().getSimpleName(),
        Toast.LENGTH_LONG
    ).show()
);
trialer.addValidator(new InstallDateValidator(10));
trialer.addValidator(new StaticDateValidator(someFutureDate.getTime()));
trialer.addValidator(new RunTimesValidator(5));
trialer.addValidator(new YourCustomValidator());
trialer.addAction(new DisplayToastAction(context, "Toast by DisplayToastAction"))
trialer.valid();

Validators

StaticDateValidator

Simple validator - it fails if given date is in the past.

val someFutureDate = Calendar.getInstance()
someFutureDate.add(Calendar.DATE, 30)
...
trialer.addValidator(StaticDateValidator(someFutureDate.time))
...

InstallDateValidator

It fails when X days have passed since installation.

val days = 10 //Int
...
trialer.addValidator(InstallDateValidator(days))
...

RunTimesValidator

It fails when X times your activity has been launched.

val runTimes = 5 //Int
...
trialer.addValidator(RunTimesValidator(runTimes))
...

CustomValidators

You are able to create your custom validators. Just implement ValidatorInterface interface. You can run Trialer with as many validators as you want.

More validators soon

Feel free to contribute and add your custom validators.

Actions

If you don't want to use TrialEndedListener, you can just use simple action, which will be run if trial ended. For now we have few actions specified below. If these actions don't meet your needs, please implement ActionInterface and create your own action.

FinishActivityAction

Closes activity if trial ended.

trialer.addAction(FinishActivityAction(activity))

DisplayToastAction

Displays toast message if trial ended.

trialer.addAction(DisplayToastAction(context, "Toast by DisplayToastAction"))
