NativeStackBlur

Android StackBlur with gradle support (only for the native method) https://github.com/kikoso/android-stackblur

As you may see, kikoso has not yet provided a way to add StackBlur as a gradle dependency easily. This library is an attempt to make the NativeBlurProcess availible through gradle without the need to import any modules or do any other configuration.

Gradle Dependency

Add this in your root build.gradle file (not your module build.gradle file):

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

Then, add the library to your project build.gradle

dependencies {
    implementation("com.github.Commit451:NativeStackBlur:latest.version.here")
}

This library is provided as a "fat" aar with native binaries for all available architectures. To reduce your APK size, use the ABI filtering/splitting techniques in the Android plugin: http://tools.android.com/tech-docs/new-build-system/user-guide/apk-splits

Usage

Usage is similar to StackBlur, but also more streamlined:

Bitmap bm = NativeStackBlur.process(source, blurRadius);

Compiling

If you want to compile the original StackBlur lib for various reasons, such as adding more architecture support, simply pull down the original StackBlur repo, navigate to the StackBlur project folder (with the res and src folders). Delete the x86 and other folders containing .so files. Also, remove the <uses-sdk block from the manifest. You will probably also get errors relating to LOCAL_SRC_FILES pointing to a missing file. Since we do not support Renderscript, just open up the Android.mk file and remove the ifneq block. Now, run ndk-build. This should output all the .so files you need within the /libs folder (ignoring the renderscript-v8.jar). This process works with commit cf19121553f50f346c48eabc7ebf04d27b074f17 of android-stackblur
