C++ (Cpp) ReleaseJavaClass示例

示例#1

文件： DeviceInfoAndroid.cpp 项目： vilonosec/dava.framework

String JniDeviceInfo::GetRegion()
{
	jclass javaClass = GetJavaClass();
	if (!javaClass)
		return "";

	intermediateStr = "";
	jmethodID mid = GetMethodID(javaClass, "GetRegion", "()V");
	if (mid)
		GetEnvironment()->CallStaticVoidMethod(javaClass, mid, 0);
	ReleaseJavaClass(javaClass);

	return intermediateStr;
}

示例#2

文件： MailSender.cpp 项目： boyjimeking/dava.framework

{
	jclass javaClass = GetJavaClass();
	if (!javaClass)
		return false;

	jmethodID mid = GetMethodID(javaClass, "SendEMail", "(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)Z");
	bool res = false;
