I have a function that saves an image from a website, and then loads it into a CCScale9Sprite. This function works great on iOS and fails on Android, the only error I get is:
05-14 16:01:02.857: D/cocos2d-x debug info(14697): dlButton save dir = /data/data/com.nds.sprite9fail/files/dlButton.jpeg
05-14 16:01:02.864: D/cocos2d-x debug info(14697): … curl performed (file != NULL)
05-14 16:01:02.864: D/cocos2d-x debug info(14697): … curl cleaned
05-14 16:01:02.864: D/cocos2d-x debug info(14697): … created regular CCSprite
05-14 16:01:02.864: A/libc(14697): Fatal signal 11 (SIGSEGV) at 0x00000038 (code=1), thread 14711 (Thread-779)
I believe it has to do with how the Scale9Sprite loads the asset because it when I run the code, it looks like the regular CCSprite does successfully load (the CCLog shows).
I am an absolute novice to Android development, so any pointers would be greatly appreciated.
I made a sample project, attached are the HelloWorld files to exhibit the issue, but for quickness, here is the function:
void HelloWorld::onEnter() {
CCLayer::onEnter();
std::string dir = CCFileUtils::sharedFileUtils()->getWritablePath();
if (dir.size() > 0 && dir[dir.size() - 1] != '/') dir.append("/");
dir.append("dlButton.jpeg");
CCLog("dlButton save dir = %s", dir.c_str());
CURL *curl = curl_easy_init();
if (curl) {
// Open up writable temp graphic.
FILE *file = fopen(dir.c_str(), "wb");
CCString* url = CCString::createWithFormat("http://www.fillmurray.com/200/300");
// Generate URL for proper image size.
// char url[64];
// sprintf(url, "fillmurray.com/%d/%d", (int)size.width, (int)size.height);
// Allow follow location for "302 File Found" redirect.
curl_easy_setopt(curl, CURLOPT_URL, url->getCString());
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, curl_write);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, file);
// Write the image to the file.
curl_easy_perform(curl);
CCLog("... curl performed (file %s NULL)", (file == NULL ? "==" : "!="));
fclose(file);
curl_easy_cleanup(curl);
CCLog("... curl cleaned");
CCSprite* testSprite = CCSprite::create(dir.c_str());
CCLog("... created regular CCSprite");
CCScale9Sprite* newSprite = CCScale9Sprite::create(dir.c_str()); // TODO: this crashes on android!?
CCLog("... created CCScale9Sprite");
CCSize size = CCDirector::sharedDirector()->getWinSize();
testSprite->setPosition( ccp(size.width/4, size.height/2) );
this->addChild(testSprite, 0);
CCSize oSize = newSprite->getOriginalSize();
newSprite->setCapInsets(CCRect(0, 0, oSize.width, oSize.height));
newSprite->setPosition( ccp(size.width*3/4, size.height/2) );
this->addChild(newSprite, 0);
CCLog("... sprites added");
// */
} else {
// failed to generate curl
curl_easy_cleanup(curl);
}
CCLog("... curl completely done");
}
