示例1: android_hardware_Camera_release
// disconnect from camera service
// It's okay to call this when the native camera context is already null.
// This handles the case where the user has called release() and the
// finalizer is invoked later.
static void android_hardware_Camera_release(JNIEnv *env, jobject thiz)
{
// TODO: Change to LOGV
LOGV("release camera");
JNICameraContext* context = NULL;
sp<Camera> camera;
{
Mutex::Autolock _l(sLock);
context = reinterpret_cast<JNICameraContext*>(env->GetIntField(thiz, fields.context));
// Make sure we do not attempt to callback on a deleted Java object.
env->SetIntField(thiz, fields.context, 0);
}
// clean up if release has not been called before
if (context != NULL) {

// clear callbacks
if (camera != NULL) {

}
// remove context to prevent further Java access
context->decStrong(thiz);
