问题 Is it possible to use the Support Renderscript Library with Gradle? If so, how do you include it in your project? 回答1: Gradle for Android has now Renderscript v8 support with only 2 lines in your build script. See answer by Austyn Mahoney. Keeping the original answer for historical purpose. Old Answer: Gradle supports native RS compilation, but not the RS support library. The reason is that the RS support library is hugely complicated compared to any other support library. The RS support

问题 Since I've migrated to androidx I can't make Renderscript run. I'm getting following exception: 2018-10-12 16:27:58.328 27195-27195/pl.qus.xenoamp2 A/zygote64: java_vm_ext.cc:504] JNI DETECTED ERROR IN APPLICATION: JNI NewGlobalRef called with pending exception java.lang.ClassNotFoundException: Didn't find class "android.support.v8.renderscript.RenderScript" on path: DexPathList[[zip file "/data/app/pl.qus.xenoamp2-xHJAddeg9oM-uGSxlvMp7A==/base.apk"],nativeLibraryDirectories=[/data/app/pl.qus

问题 In order to write efficient code, you should use the simplest possible data types. This is even more true for Renderscript, where the same calculation is repeated so many times in a kernel. Now, I wanted to write a very simple kernel, that takes an (color) bitmap as input and produces an int[] array as output : #pragma version(1) #pragma rs java_package_name(com.example.xxx) #pragma rs_fp_relaxed uint __attribute__((kernel)) grauInt(uchar4 in) { uint gr= (uint) (0.21*in.r + 0.72*in.g + 0.07

问题 I'm trying to write a simple kernel for image processing; I was planning on storing the channel of image in the 'z' coordinate of an allocation. I think this should be possible based on the documentation: A kernel may access the coordinates of the current execution using the x, y, and z arguments. These arguments are optional, but the type of the coordinate arguments must be uint32_t. I tried to write an empty kernel which uses the 'z' coordinate: #pragma version(1) #pragma rs java_package

问题 I've been trying to create a live wallpaper on android. I'm using the tutorial mentioned below. http://mobile.tutsplus.com/tutorials/android/getting-started-with-renderscript-on-android/ I've copied the source code and also installed the support libraries. I however cannot find support v8 in my SDK folders located in my program files in the windows system :( These imports work for me after i changed my project properties and added renderscript.target=18 renderscript.support.mode=true sdk

问题 Whenever I make changes to Renderscript and try running the emulator, the changes are not reflecting. I tried clean and build, invalidate the cache and restart but nothing helps. The changes reflect only when I delete the renderscript file and recreate the rs file with a different name, but this is cumbersome to do every time. Any fix for this? I'm using build tools version 25.0.3 and API 26 in Emulator. I understand the stack overflow community on renderscript is limited. So any help will be

问题 I'm incrementing the value of a global in RS with the aim of passing it back to Java on kernel completion. rsDebug shows the value rising on each iteration, but mScript.get_var() returns the initial value of 1. What's the right way to get the last value of MAX? RS: int MAX = 1; void root(const input* in, float* out){ MAX = MAX+1; rsDebug("MAX",MAX); *out = atan2(in->first, in->second); } Java: float[] out = new float[100000]; mScript.forEach_root(mInAllocation, mOutAllocation); mOutAllocation

问题 I'm completely new to RenderScript. I was trying to get a simple example shown by Romain Guy in http://www.youtube.com/watch?v=5jz0kSuR2j4 working. First off, here's the code. MainActivity.java package com.example.rsgray; import android.app.Activity; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.os.Bundle; import android.renderscript.Allocation; import android.renderscript.RenderScript; import android.view.Window; import android.view.WindowManager;

问题 Background I want to research about creating Renderscript scripts on Android and Renderscript in general, and over the past year, Android-Studio became the only IDE that Google supports for Android apps development.

问题 When using RenderScript with the support libraries I get this error on Motorola iRazr (Android 4.1.2) Error loading RS jni library: java.lang.UnsatisfiedLinkError: Couldn't load RSSupport: findLibrary returned null Everything works fine on Samsung Galaxy S3.
