问题 I have a library, say LIB, which exposes the quite a few APIs and classes for use by application developers. If there are more than one applications that use LIB on the phone, I want only one instance of LIB to be created and running. It is somewhat similar to what Android Platform Services like LocationManager, SensorManager, PackageManager etc. Specifically, there are two problems that are to be addressed:- How to make sure that there is only one instance of LIB ? How to deploy LIB(separate

问题 I'm still unsure on what to put into the shared folder. If I'm doing RPC requests, and sending Pojos from the client to the server and vice versa, do I have to put them into the shared folder (because they are used by both - client and server). EDIT Maybe I've used the wrong term but when I said Pojo I actually meant DTO . 回答1: You don't have to put the RPC POJOs in a shared folder but if you keep them in the client folder, the server would be dependent on the client package because the Pojos

问题 AFAIK, memory in Java is based on heap from which the memory is allotted to objects dynamically and there is no concept of shared memory. If there is no concept of shared memory, then the communication between Java programs should be time consuming. In C where inter-process communication is quicker via shared memory compared to other modes of communication. Correct me if I'm wrong. Also what is the quickest way for 2 Java progs to talk to each other. 回答1: Since there is no official API to

问题 This question is more like a discussion about how you guys would do it. I'm developing an application that has an Avatar Creation, but this creating occurs across two different Activities. In the first one the user selects whether is man or a woman and a name, in the next Activity the user has to select his face, hair, clothes and etc. Since the views for hair and etc changes if the user is a man or a woman how would you implement a way to pass the gender value to all the Views? I was

问题 I have a c structure like this : struc str{ int values[10]; }str In a posix so like fedora i copied this structure to a part of shared memory ( shm_open , ftruncate , mmap and memcpy ) and I got a pointer to structure from shm. Now how do I change a value in the values array by using this pointer (*ptr). Imagine i want to do str->values[5] = 10; how to I do that using the pointer. 回答1: Just use the pointer: struct str *p = ptr; p->values[5] = 10; 来源： https://stackoverflow.com/questions

问题 I have a c++ program where I'm creating multiple threads and having them access a shared array. Everytime I want one thread to access the array, I call pthread_mutex_lock(&mutex); access the array and then call pthread_mutex_unlock(&mutex); All threads loop continuously until they've accessed the array a certain number of times. Thus they aren't just accessing the array once, but instead accessing it several times. Now, when I execute my program just as it is, whichever thread gets the mutex

问题 I need to activate this mail() function is there any way of doing this only on my hosting account (being on shared account)? Thanks! 回答1: Is this a case of the mail() function not operating? Most shared hosting accounts have it enabled. The only people who have the option to make that kind of change to the server configuration (as far as I know) is the Server Admin. If you are sure that the mail() function is not available on your account, contact your Webhost Support and ask them about it.
