Looks like the CameraService isn't getting a reference to my client.
Here's the relevant code from CameraService.cpp. I wonder if I can set
some parameter to give CameraService enough of a chance to get the
reference to my client.
// Safely retrieves a strong pointer to the client during a hardware
callback.
sp<CameraService::Client> CameraService::Client::getClientFromCookie
(void* user)
{
sp<Client> client = 0;
CameraService *service = static_cast<CameraService*>(user);
if (service != NULL) {
Mutex::Autolock ourLock(service->mLock);
if (service->mClient != 0) {
client = service->mClient.promote();
if (client == 0) {
LOGE("getClientFromCookie: client appears to have
died");
service->mClient.clear();
}
} else {
LOGE("getClientFromCookie: got callback but client was
NULL");
}
}
return client;
}
