An easy way to persist and run code block only as many times as necessary on Android.

Download

Download Jitpack

Gradle

And add a dependency code to your module's build.gradle file.

dependencies {
    implementation "com.github.skydoves:only:1.0.3"
}

Usage

Initialize

Fisrt, initialize the Only using init() method like below.
This code can be initialized on Application class only once.

Only.init(context)

onDo

Below codes will run the showIntroPopup() only three times using onDo method.

Only.onDo("introPopup", times = 3) {
  showIntroPopup()
}

// kotlin dsl
only("introPopup", times = 3) {
  onDo {
    showIntroPopup()
  }
}

onDone

Below codes will run the doSomethingAfterDone() and toast("done") after run the onDo block codes three times.

Only.onDo("introPopup", times = 3,
  onDo = {
    showIntroPopup()
    toast("onDo only three times")
  },
  onDone = {
    doSomethingAfterDone()
    toast("done")
  })

// kotlin dsl
only("introPopup", times = 3) {
  onDo {
    showIntroPopup()
    toast("onDo only three times")
   }
  onDone {
    doSomeThingAfterDone()
    toast("done")
  }
}

onLastDo, onBeforeDone

We can do pre and post-processing using onLastDo, onBeforeDone options.

only("Intro", times = 3) {
  onDo {
    showIntroPopup()
    toast("onDo only three times")
  }
  onLastDo { // executes only once after finished onDo block 3 times.
    toast("finished onDo")
  }
  onBeforeDone { // executes only once before run onDone block.
    toast("starts onDo")
  }
  onDone {
    doSomethingAfterDone()
    toast("done")
  }
}

We can apply it for repeating x times.
Below codes shows review-popup 3 times and checks the user reviewed or not in onLastDo block.
If not, clear times using the Only.clearOnly method, and repeat it the first time again.

only("Intro", times = 3) {
  onDo { showReviewRequestPopup() }
  onLastDo { // executes only once after finished onDo block 3 times.
    if (!isRequested) {
      Only.clearOnly(this@only.name)
    }
  }
}

Version Control

We can renew the persistence times for controlling the version using version option.
If the version is different from the old version, run times will be initialized 0.

Only.onDo("introPopup", times = 3,
  onDo = { showIntroPopup() },
  onDone = { doSomethingAfterDone() },
  version = "1.1.1.1"
)

// kotlin dsl
only("introPopup", times = 3) {
  onDo { showIntroPopup() }
  onDone { doSomethingAfterDone() }
  version("1.1.1.1")
}

Create Using Builder

We can run Only using Only.Builder class like below.

Only.Builder("introPopup", times = 3)
  .onDo { showIntroPopup() }
  .onDone { doSomethingAfterDone() }
  .version("1.1.1.1")
  .run()

OnlyOnce, OnlyTwice, OnlyThrice

Here is some useful kotlin-dsl functions.

onlyOnce("onlyOnce") { // run the onDo block codes only once.
  onDo { doSomethingOnlyOnce() }
  onDone { doSomethingAfterDone() }
}

onlyTwice("onlyTwice") { // run the onDo block codes only twice.
  onDo { doSomethingOnlyTwice() }
  onDone { doSomethingAfterDone() }
}

onlyThrice("onlyThrice") { // run the onDo block codes only three times.
  onDo { doSomethingOnlyThrice() }
  onDone { doSomethingAfterDone() }
  version("1.1.1.1")
}

Clear Data

We can optionally delete the stored Only target data or delete the whole Only data.

Only.clearOnly("introPopup") // clears a saved target Only data.
Only.clearAllOnly() // clears all of the target Only data on the application.

View Extension

Below codes will show the button view only once.

button.onlyVisibility(name = "myButton", times = 1, visible = true)

Toast Extension

Below codes will show toast only x times.

onlyToast("toast", 3, "This toast will be shown only three times.")
onlyOnceToast("toast1", "This toast will be shown only once.")
onlyTwiceToast("toast2", "This toast will be shown only twice.")
onlyThriceToast("toast3", "This toast will be shown only thrice.")

Marking

We can mark data to the Only target.

only("introPopup", times = 3) {
  onDo { showIntroPopup() }
  onDone { doSomethingAfterDone() }
  mark("abc") // marks only once when run by kotlin dsl or builder class.
}

Only.mark("introPopup", 3) // changes marking using mark method.
val marking = Only.getMarking("introPopup") // gets the marked data.

Debug Mode

Sometimes on debug, we don't need to persist data and replay onDone block.
onlyOnDoDebugMode helps that ignore persistence data and onDone block when initialization. It runs only onDo block.

Only.init(this)
   .onlyOnDoDebugMode(true)

Usage in Java

Here are some usages for Java developers.

int times = Only.INSTANCE.getOnlyTimes("IntroPopup") ;
if (times < 3) {
    Only.INSTANCE.setOnlyTimes("IntroPopup", times + 1);
    showIntroPopup();
}

Or we can run Only in java project using Only.Builder and Function0.

new Only.Builder("introPopup", 1)
    .onDo(new Function0<Unit>() {
      @Override
      public Unit invoke() {
        doSomethingOnlyOnce();
        return Unit.INSTANCE;
      }
    })
    .onDone(new Function0<Unit>() {
      @Override
      public Unit invoke() {
        doSOmethingAfterDone();
        return Unit.INSTANCE;
      }
    }).run(); // run the Only
