Compatibility

This library is compatible from API 16 (Android 4.1).

Download

Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

Add the dependency

dependencies {
    compile 'com.github.jetradarmobile:android-snowfall:1.2.1'
}

Usage

Default implementation with round snowflakes:

<com.jetradarmobile.snowfall.SnowfallView
      android:layout_width="match_parent"
      android:layout_height="match_parent"/>

Fully customized implementation:

<com.jetradarmobile.snowfall.SnowfallView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      app:snowflakesNum="250"
      app:snowflakeAlphaMin="150"
      app:snowflakeAlphaMax="255"
      app:snowflakeAngleMax="5"
      app:snowflakeSizeMin="8dp"
      app:snowflakeSizeMax="32dp"
      app:snowflakeSpeedMin="4"
      app:snowflakeSpeedMax="12"

  • Add general fixes and optimizations to the project

    Add general fixes and optimizations to the project

    Change list:

    • Remove lazy accessors for fields. They are adding extra overhead in terms of memory and they are way too heavy for one threaded environment complex for Android world
    • Remove kotlin stdlib methods in onDraw. They are just adding extra allocations while trying to draw on Android canvas
    • Some code overall clean up
    • Migrate sample to AndroidX
    • Update dependencies for Kotlin and plugins

  • Fix memory leak related to inner HandlerThread

    Fix memory leak related to inner HandlerThread

    We were using this library and noticed that it would leak the activity that contains the SnowfallView. This was due to the HandlerThread being an inner class, therefore having a reference to the view.

    I also ensured that the thread is not started until the view is attached. And that we call quit() when detached.

    I tested the changes with the sample app and the android studio memory analyser.

  • Add ability to stop snowfall without making it disappear

    Add ability to stop snowfall without making it disappear

    Previously, the only way to stop the snowfall was to make the SnowfallView GONE, meaning that the snow would immediately disappear. With this change, one can stop the snowfall, but any snowflakes that are already visible on the screen will continue falling.

    This functionality was added for use within the Expedia app in December 2017. ezgif-4-d8771ec81e

  • Setting visibility to visible when invoking restartFalling

    Setting visibility to visible when invoking restartFalling

    If I invoke stopFalling() on SnowfallView and wait for all snowflakes to fall out of view, calling restartFalling() does not render the snowflakes unless I set the visibility back to VISIBLE.

    Ideally this should be taken care of in restartFalling().

    Also cleaned up a few lint warnings.

    Performance issue with recyclerview

    I am trying to integrate this snowfall effect in recyclerview and it is looking quite good. But without snowfall effect recyclerview is scrolling smoothly and integration of snowfall makes recyclerview scrolling hazy.

    Do you know this is happening ? Any direction and guide will be really helpful. Thanks.

  • Page loading slow when i use snow fall animation.

    Page loading slow when i use snow fall animation.

    I have my Editext field and snow fall animations at the same page. When i try to enter text in the edittext field it takes more time for the text to be show. It is because of the animations in the page makes the text to appear slow. Is there any way to view the text as soon as possible after it is being typed?

    Thanks in Advance.
