问题
I am trying to use the Android Renderscript support library on devices of API 16 and up, following the steps described here. So far things have not gone smoothly.
My Renderscript code is listed 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.g, 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.g, 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.g, 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. If I click ADT/Help/About ADT/Installation Details, I see that all components have been upgraded to 22.3.0, except the Developer Tools, which 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 aforementioned steps. I also made changes to incorporate Tim Murray's comments.
proguard.config=C:/android/adt-bundle-windows-x86_64/sdk/tools/proguard/proguard-android.txt:proguard-project.txt
# Project target.

Finally, in my project's properties, I added external JARs into the Java Build Path:
renderscript-v8.jar - C:\android\adt-bundle-windows-x86_64\sdk\build-tools\19.0.0\renderscript\lib
The code built without any issues. Then I tested it on a few devices. Here are the test results.
Nexus 7 (2012 version, upgraded to Android 4.4) The code ran to finish without crashing. However, after the Renderscript is called the 1st time, updating the ImageView results in a blank display. Apparently the output bitmap is not properly written into.
Huawei Mate (Android 4.1.2) The code crashes right after loading from ADT. Below is a selection of error messages (the post body is limited to 30k characters, so I can't post everything):

I'd appreciate if someone could look into the issues, whether it's bugs in my code or Android SDK issues. Comments/suggestions are welcome Thanks!
[EDIT] I stripped un-related stuff from my code, and am posting the complete code here, in hope that someone could repeat my problem, and find a solution. I also added more test results.
回答1:
Well. I'm not sure if this is still needed and if it will fix your problem, but I suggest you try to use Android Plugin for Gradle 1.5.0
This must be set in your project's build.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 the latest version.
