+![Check and compile](https://github.com/xmartlabs/AndroidSwissKnife/workflows/Check%20and%20compile/badge.svg?branch=master)
+[![Release](https://jitpack.io/v/xmartlabs/AndroidSwissKnife.svg)](https://jitpack.io/#xmartlabs/AndroidSwissKnife)
+
+A library that contains a series of extensions, helpers, and useful classes used in most of [Xmartlabs' Android Projects](https://www.xmartlabs.com/).
+
+It's divided into a series of modules with different proposes:
+- [Core](/core): Core extensions of the application, for example view's and resource's extensions.
+- [Navigation](/navigation): Navigation extensions and useful helper classes related to [Navigation Architecture Component].
+- [Navigation-debug](/navigation-debug): A series of extensions and useful tools to debug and log important information of the [Navigation Architecture Component].
+- [Reflection](/reflection): A series of extensions useful when you are dealing with Reflection.
+
+## Setup
+Add library to project dependencies with JitPack.
+
+```groovy
+repositories {
+    maven { url "https://jitpack.io" }
+}
+
+dependencies {
+    implementation "com.github.xmartlabs.AndroidSwissKnife:core:${master-latest-hash-commit}"
+    implementation "com.github.xmartlabs.AndroidSwissKnife:navigation:${master-latest-hash-commit}"
+    implementation "com.github.xmartlabs.AndroidSwissKnife:navigation-debug:${master-latest-hash-commit}"
+    implementation "com.github.xmartlabs.AndroidSwissKnife:reflection:${master-latest-hash-commit}"

+# Navigation Debug Module
+This module contains a series of extensions that helps you to debug and understand the current navigation controller state when you are working with [Android Navigation Component](https://developer.android.com/guide/navigation/navigation-getting-started).
+If you want to include this dependency only in debug mode, you can use `debugImplementation` method or use a custom flavour.
+
+```groovy
+dependencies {
+    // Only include the dependency in debug builds
+    debugImplementation 'com.github.xmartlabs.AndroidSwissKnife:navigation-debug:$master-latest-hash-commit'
+
+    // Only include the dependency in dev's flavour builds
+    devImplementation 'com.github.xmartlabs.AndroidSwissKnife:navigation-debug:$master-latest-hash-commit'
+}
+```
+
+
+## Dependencies:
+- [Navigation Fragment Dependency (`androidx.navigation:navigation-fragment-ktx`)](https://developer.android.com/jetpack/androidx/releases/navigation).
+- [Core Module](../core) 
+- [Navigation Module](../navigation) 
+- [Reflection Module](../reflection) 
+
+## Module's content:
+
+### [NavigationDebugExtensions](./src/main/java/com/xmartlabs/swissknife/navigationdebug/NavigationDebugExtensions.kt)
+It contains a series of extensions to log the current navigation graph state.
+The extensions uses reflection, so it's recommended used only in debug mode.

+# Navigation Module
+
+It contains the core extensions needed when you are dealing with the [Android Navigation Component](https://developer.android.com/guide/navigation/navigation-getting-started).
+
+## Dependencies:
+- [Navigation Fragment Dependency (`androidx.navigation:navigation-fragment-ktx`)](https://developer.android.com/jetpack/androidx/releases/navigation).
+- [Core Module](../core) 
+
+## Module's content:
+
+### [NavigationExtensions](./src/main/java/com/xmartlabs/swissknife/navigation/NavigationExtensions.kt)
+A series of extensions to navigate safely.
+Suppose that you have a button that navigates from the screen `A` to the screen `B`.
+If the user clicks this button twice quickly, the first time will navigate from `A` to `B`.
+However, the second one the navigation component will try to navigate from `A` to `B` making crash the app because the current node is `B`.
+These extensions help to avoid these cases.
+
+### [Keep Nav State](./src/main/java/com/xmartlabs/swissknife/navigation/keep_nav_state)
+This package, contains the [`KeepStateNavigator`] class, which saves the Fragment state, when the fragment is removed from the Fragment Manager.
+The navigator defines the `keep_state_fragment` tag, that should be used in the navigation graph to indicates to use this Navigator.
+For example, your graph will look something like:
+
+To use the [`KeepStateNavigator`], you can add the controller manually in your NavHostFragment or use the [`KeepStateNavHostFragment`], a `NavHostFragment` witch provides [`KeepStateNavigator`] support.
+A common use of this tool is when you have a fragment that contains multiple fragments that can change and you don't want to lose the child Fragment's state.
+The parent fragment can define the child navigation fragment as: 
+```xml
+<fragment
+    android:id="@id/keepStateNavHostContentFragment"
+    android:layout_width="match_parent"
+    android:layout_height="match_parent"
+    android:name="com.xmartlabs.swissknife.navigation.keep_nav_state.KeepStateNavHostFragment"
+    app:navGraph="@navigation/nav_graph"
+    />
+```
+The Navigation graph will look like:
+```xml
+<navigation
+    xmlns:android="http://schemas.android.com/apk/res/android"
+    xmlns:app="http://schemas.android.com/apk/res-auto"
+    android:id="@+id/nav_graph"
+    app:startDestination="@id/fragmentA"
+    >
+
+    <keep_state_fragment
+        android:id="@+id/fragmentA"
+        android:name="...FragmentA"
+        android:label="FragmentA"
+        />
+
+    <keep_state_fragment
+        android:id="@+id/fragmentB"
+        android:name="...FragmentB"
+        android:label="FragmentB"
+        />
+
+
+    <action
+        android:id="@+id/action_display_fragment_a"
+        app:destination="@id/fragmentA"
+        />
+
+    <action
+        android:id="@+id/action_display_fragment_b"
+        app:destination="@id/fragmentB"
+        />
+
+</navigation>
+```
