	allprojects {
 		repositories {
 			... 			maven {
 url  https://jitpack.io  
}
 		
}
 	
}
 
  1. Add the dependency

 dependencies {

How to

Simple Validation

val myinput = findViewById<TextInputLayout>(R.id.my_input)  myinput.validate(
  default = "my default text",
  validators = listOf(

{
 text -> t.isNotEmpty() 
}
,

...
  ),
  error = "my error text",
  onValid = {
 validText ->

 // do something with the valid text

}
 )

Using the Validation Object

Error message for each validation condition
val phoneNumberValidator = TextInputValidator(
  defaultString = "My default text",
  validators = listOf(

{
 text -> (text.length > 12) to "Length must be greater than 12"
}
,

{
 text -> text.startsWith( + ) to "Input must start with  + "
}
,

...
  ) )
Single error message
val phoneNumberValidator = TextInputValidationObj(
  default = "My default text",
  error = "Please enter a valid phone number",
  validators = listOf(

{
 text -> text.length > 12
}
,

{
 text -> text.startsWith( + )
}
,

...
  ) )  myinput.validate(phoneNumberValidator){
 validText ->
  // do something with the valid text 
}

Validate input After setting the validation object on the TextInputLayout you can validate it anywhere on your code

myinput.valid() // Return a Boolean.

jraf-android-util is a collection of general purpose utilities for Android.

Why it exists

There is currently no way for an android application to catch and report ANR errors. If your application is not in the play store (either because you are still developing it or because you are distributing it differently), the only way to investigate an ANR is to pull the file /data/anr/traces.txt.

What it does

It sets up a watchdog timer that will detect when the UI thread stops responding. When it does, it raises an error with the main thread's stack trace.

droid-fu is a utility library for your daily Android needs.

NOTICE: This project has been discontinued. Developers are putting all efforts into ignition now, which is basically a rewritten but API breaking version of Droid-Fu that aims to have better project structure, better and less intrusive APIs, better documentation (we have samples now!) and proper release and issue management.

Custom Tabs with Material Design animations for pre-Lollipop devices.

RouteDrawer wraps Google Directions API using RxJava for Android so developers can download, parse and draw path on the map in very fast and flexible way.

The library contains two main parts:

  • RouteApi is responsible for sending request to Google's Direction API and handling the response
  • DrawerApi is responsible for drawing the path on the map
