問題描述

我正在嘗試將 Renderscript 支持庫包含到我的項(xiàng)目中.我收到以下錯誤.

I am trying to include the Renderscript support library into my project. I am getting the following error.

android.support.v8.renderscript.RSRuntimeException: Error loading RS jni library: java.lang.UnsatisfiedLinkError: Couldn't load rsjni: findLibrary returned null

我沒有使用任何 Renderscript jar 文件，我正在嘗試通過 Gradle 使用它.

I am not using any Renderscript jar files, I am attempting to use it via Gradle.

這是我的 Gradle.build 文件

Here are my Gradle.build files

頂級

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.2.3'
}
}

ext {
compileSdkVersion="Google Inc.:Google APIs:22"
buildToolsVersion="23.0.1"
playStoreMinSdkVersion=16
amazonStoreMinSdkVersion=8
targetSdkVersion=22
versionCode=20
versionName="3.3.0"
runProguard=true
zipAlign=true
proguardConfiguration='../proguard.config'
}

allprojects {
repositories {
    jcenter()
}
}

特定應(yīng)用

defaultConfig {
    applicationId "**REMOVED**"
    //noinspection GroovyAssignabilityCheck
    targetSdkVersion rootProject.ext.targetSdkVersion
    //noinspection GroovyAssignabilityCheck
    versionCode rootProject.ext.versionCode
    //noinspection GroovyAssignabilityCheck
    versionName rootProject.ext.versionName

    renderscriptTargetApi 23
    renderscriptSupportModeEnabled true
}

我嘗試的一切&在 stackoverflow 上找到可能的解決方案不起作用.我的 proguard 配置中也包含了這個

Everything I try & find as possible solutions on stackoverflow are not working. I also have this included in my proguard config

#RenderScript
-keepclasseswithmembernames class * {
native <methods>;
}
-keep class android.support.v8.renderscript.** { *; }

這是我實(shí)際使用渲染腳本的實(shí)現(xiàn)，這也是它在調(diào)用時導(dǎo)致我的應(yīng)用程序崩潰的地方.

Here is the implementation where I actually use renderscript, also this is where it causes my app the crash when called.

public static BitmapDrawable Blur ( View view ){

    Bitmap image = GetScreenshot( view );

    int width = Math.round( image.getWidth() * DEFAULT_BITMAP_SCALE );
    int height = Math.round( image.getHeight() * DEFAULT_BITMAP_SCALE );

    Bitmap inputBitmap = Bitmap.createScaledBitmap( image, width, height, false );

    Bitmap outputBitmap = Bitmap.createBitmap( inputBitmap );

    RenderScript rs = RenderScript.create( view.getContext() );
    ScriptIntrinsicBlur intrinsicBlur = ScriptIntrinsicBlur.create( rs, Element.U8_4(rs) );

    Allocation tmpIn = Allocation.createFromBitmap(rs, inputBitmap);
    Allocation tmpOut = Allocation.createFromBitmap( rs, outputBitmap );

    intrinsicBlur.setRadius( DEFAULT_BLUR_RADIUS );
    intrinsicBlur.setInput( tmpIn );
    intrinsicBlur.forEach( tmpOut );

    tmpOut.copyTo( outputBitmap );

    inputBitmap.recycle();
    rs.destroy();

    return new BitmapDrawable( outputBitmap );
}

這是確切的行

RenderScript rs = RenderScript.create( view.getContext() );

推薦答案

很遺憾，Renderscript 不適用于 armeabi 架構(gòu).好的一面是您可以在運(yùn)行時檢查設(shè)備的架構(gòu)，而不是在這些設(shè)備上運(yùn)行 Renderscript 代碼:

Unfortunately Renderscript is not available for the armeabi architecture. The bright side is that you can check at runtime to see the architecture of the device and not run the Renderscript code on those devices:

System.getProperty("os.arch");

在 android 錯誤跟蹤器上還存在一個問題，他們指出:

There is also an issue open on the android bug tracker, where they state:

我們僅提供 armeabi-v7a 的支持庫.這是一個已知的限制.

We only ship the support library for armeabi-v7a. This is a known limitation.

https://code.google.com/p/android/issues/detail?id=68520

如果您想在 armeabi 設(shè)備上實(shí)現(xiàn)沒有 Renderscript 的模糊，您可以簡單地使用 Bitmap.createScaledBitmap 設(shè)置 filter 到 true.

If you want to implement a blur without Renderscript on armeabi devices, you can simply downscale the image with Bitmap.createScaledBitmap setting filter to true.
