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"))
