# Lifeline

Easy access to important Android lifecycle information

[![Build Status](https://travis-ci.org/Commit451/Lifeline.svg?branch=master)](https://travis-ci.org/Commit451/Lifeline)

[![](https://jitpack.io/v/Commit451/Lifeline.svg)](https://jitpack.io/#Commit451/Lifeline)

# Basic Usage

In your `Application` class

```kotlin

Lifeline.init(this)

```

If you want to check to see if the app is in the foreground:

```kotlin

val inForeground = Lifeline.isInForeground()

```

If you want to track time the app has been paused:

```kotlin

//ideally in your onResume

val time = Lifeline.timeSpentOutsideApp()

```

If you want to track when the app is backgrounded:

```kotlin

Lifeline.registerOnBackgroundedListener {

    Toast.makeText(this, "On backgrounded", Toast.LENGTH_SHORT)

            .show()

}

```

If you want to track when the app is foregrounded:

```kotlin

Lifeline.registerOnForegroundedListener {

    Toast.makeText(this, "On foregrounded", Toast.LENGTH_SHORT)

            .show()

}

```

Make sure to unregister these when appropriate
