Я пытаюсь использовать библиотеку поддержки Android Renderscript на устройствах с API 16 и выше, следуя инструкциямописано здесь, Пока что дела пошли не так гладко.

Мой код Renderscript указан ниже.

#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);
}

Сначала я обновил инструменты Android SDK до 22.3, а инструменты платформы SDK - 19. Если я нажму ADT / Справка / О ADT / Сведения об установке, я вижу, что все компоненты были обновлены до 22.3.0, кроме инструментов разработчика, которые все еще 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

  Tracer for OpenGL ES  22.3.0.v201310242005-887826 com.android.ide.eclipse.gldebugger.feature.group    The Android Open Source Project

Затем я отредактировал свой файл "project.properties", как предложено в вышеупомянутых шагах. Я также внес изменения, чтобы включить комментарии Тима Мюррея.

proguard.config=C:/android/adt-bundle-windows-x86_64/sdk/tools/proguard/proguard-android.txt:proguard-project.txt

# Project target.

renderscript.target=18

В своем Java-коде я убедился, что пакеты из библиотеки поддержки импортированы. Ниже приведен полный файл Java:

Наконец, в свойствах моего проекта я добавил внешние JAR-файлы в Java Build Path:

renderscript-v8.jar - C:\android\adt-bundle-windows-x86_64\sdk\build-tools\19.0.0\renderscript\lib 

Код собран без проблем. Затем я проверил это на нескольких устройствах. Вот результаты теста.

Nexus 7 (версия 2012 года, обновлена до Android 4.4) Код работал до конца без сбоев. Однако после первого вызова Renderscript обновление ImageView приводит к пустому отображению. Видимо, выходной битовый массив неправильно записан.

Huawei Mate (Android 4.1.2) Код вылетает сразу после загрузки из ADT. Ниже приведен выбор сообщений об ошибках (объем сообщения ограничен 30k символами, поэтому я не могу опубликовать все):

Я был бы признателен, если бы кто-то мог разобраться с проблемами, будь то ошибки в моем коде или проблемы с Android SDK. Комментарии / предложения приветствуются Спасибо!
