Problems with Java – renderscript support library
•
Java
I try to use the Android renderscript support library on API 16 and later devices, and follow the steps described here So far, things have not gone well
My renderscript code is shown below
#pragma version(1)
#pragma rs java_package_name(com.xxx.renderscript.test)
#include "rs_time.rsh"
rs_script flipScript;
rs_allocation gIn;
rs_allocation gOut;
int width;
int height;
int direction = 0;
void root(uchar4 *v_out,const void *usrData,uint32_t x,uint32_t y) {
if(direction == 0) { // flip horizontally
const uchar4 *element = rsGetElementAt(gIn,width - x,y);
float4 color = rsUnpackColor8888(*element);
float4 output = {color.r,color.g,color.b};
*v_out = rsPackColorTo8888(output);
}
else if(direction == 1) { // flip vertically
const uchar4 *element = rsGetElementAt(gIn,x,height - y);
float4 color = rsUnpackColor8888(*element);
float4 output = {color.r,color.b};
*v_out = rsPackColorTo8888(output);
}
else if(direction == 2) { // rotate left
const uchar4 *element = rsGetElementAt(gIn,width - y,x);
float4 color = rsUnpackColor8888(*element);
float4 output = {color.r,color.b};
*v_out = rsPackColorTo8888(output);
}
else if(direction == 3) { // rotate right
const uchar4 *element = rsGetElementAt(gIn,y,height - x);
float4 color = rsUnpackColor8888(*element);
float4 output = {color.r,color.b};
*v_out = rsPackColorTo8888(output);
}
}
void flip(int testIdx) {
int64_t t0,t1;
int64_t t;
t0 = rsUptimeNanos();
rsForEach(flipScript,gIn,gOut);
t1 = rsUptimeNanos();
t = t1 - t0;
rsDebug(" flip: timer on RS side: ",t);
}
First, I upgraded my android SDK tools to 22.3 and my SDK platform tools to 19.3 If I click ADT / help / about ADT / installation details, I see that all components have been upgraded to 22.3 0, except developer tools, it is still 21.0 1：
Android DDMS 22.3.0.v201310242005-887826 com.android.ide.eclipse.ddms.feature.group The Android Open Source Project Android Developer Tools 21.0.1.201212060302 com.android.ide.eclipse.adt.package.product null Android Development Tools 22.3.0.v201310242005-887826 com.android.ide.eclipse.adt.feature.group The Android Open Source Project Android Hierarchy Viewer 22.3.0.v201310242005-887826 com.android.ide.eclipse.hierarchyviewer.feature.group The Android Open Source Project Android Native Development Tools 22.3.0.v201310242005-887826 com.android.ide.eclipse.ndk.feature.group The Android Open Source Project Android Traceview 22.3.0.v201310242005-887826 com.android.ide.eclipse.traceview.feature.group The Android Open Source Project Tracer for OpenGL ES 22.3.0.v201310242005-887826 com.android.ide.eclipse.gldebugger.feature.group The Android Open Source Project
Then I edited my "project. Properties" file as suggested in the above steps I also made changes and added Tim Murray's comments
proguard.config=C:/android/adt-bundle-windows-x86_64/sdk/tools/proguard/proguard-android.txt:proguard-project.txt # Project target. target=android-18 renderscript.target=18 renderscript.support.mode=true #sdk.buildtools=19.0.0

Finally, in my project properties, I add an external jar to the Java build path:
renderscript-v8.jar - C:\android\adt-bundle-windows-x86_64\sdk\build-tools\19.0.0\renderscript\lib
There are no problems with code construction Then I tested it on several devices Here are the test results
Nexus 7 (2012 version, upgraded to Android 4.4) code runs without crash However, after the first call to renderscript, updating the ImageView will result in blank display Obviously, the output bitmap is not written correctly

I would appreciate it if someone could check the problem, whether it's an error in my code or an Android SDK problem Welcome comments / suggestions, thank you!
[editor] I deleted irrelevant things from my code and released the complete code here. I hope someone can repeat my problem and find a solution I also added more test results
Solution
OK I'm not sure if this is still needed if it can solve your problem, but I suggest you try using the Android plug-in to support gradle 1.5 0
This must be done in the project's build Settings in gradle (not in app build.gradle)
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
}
And use buildtoolsversion 22.0 1 or 23.0 2 or latest version
