我正在尝试将 Renderscript 支持库包含到我的项目中.我收到以下错误.
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
我没有使用任何 Renderscript jar 文件,我正在尝试通过 Gradle 使用它.
I am not using any Renderscript jar files, I am attempting to use it via Gradle.
这是我的 Gradle.build 文件
Here are my Gradle.build files
顶级
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()
}
}
特定应用
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
}
我尝试的一切&在 stackoverflow 上找到可能的解决方案不起作用.我的 proguard 配置中也包含了这个
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.** { *; }
这是我实际使用渲染脚本的实现,这也是它在调用时导致我的应用程序崩溃的地方.
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 );
}
这是确切的行
RenderScript rs = RenderScript.create( view.getContext() );
很遗憾,Renderscript 不适用于 armeabi
架构.好的一面是您可以在运行时检查设备的架构,而不是在这些设备上运行 Renderscript 代码:
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 错误跟踪器上还存在一个问题,他们指出:
There is also an issue open on the android bug tracker, where they state:
我们仅提供 armeabi-v7a 的支持库.这是一个已知的限制.
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
设备上实现没有 Renderscript 的模糊,您可以简单地使用 Bitmap.createScaledBitmap
设置 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
.
