Gradle plugin to optimize png files and reduce resultant apk size within an Android project.
With this plugin you will be able to optimize the png files size inside your AndroidStudio project.
It works over the folder in which the resource merging was executed, by default in a Mac OSX system is app\build\intermediates\res\merged.
By doing this, all original png files are kept under /res folder and this optimization could be undone just cleaning the project.
In order to perform an optimization task, this plugin offers 2 different ways of file compression:
- Pngtastic library, which brings its own compressor.
- Zopfli, which offers ridiculously good compression ratios in exchange of low compression speed.
You can find an explanation from Colt McAnlis about why you should optimize your pngs Reducing PNG file Size and Smaller PNGs, and Android’s AAPT tool

Just click on Sync project with gradle files button
In build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.fabiomsr:drawable-optimizer-gradle-plugin:1.0.4'
}
}And in app\build.gradle
// Make sure this line comes *after* you apply the Android plugin (apply plugin: 'com.android.application')
apply plugin: 'org.fabiomsr.drawableoptimizer'No configuration is needed by default, but if you want you can configure the following parameters. Every time the configuration changes the project must be cleaned.
In app\build.gradle
drawableOptimizer {
optimizer = 'zopfli'
compressionLevel = 9
iterations = 15
onlyOnRelease = true
logLevel = 'info'
}| Parameter | Description | Values | Default Value |
|---|---|---|---|
| optimizer | Compressor to use | zopfli or pngtastic | zopfli |
| compressionLevel | Compression level (useful for pngtastic compressor) | 0-9 allowed | Brute forces with every allowed value |
| iterations | Compression iterations number (useful for zopfli) | > 0 | 15 |
| onlyOnRelease | Only release signed optimization | true or false | false |
| logLevel | Output Logging level | none, debug, info or error | info |
