[android-developers] Netbeans for Linux and Android
I am thinking of writing C/C++, java for Linux and Android, on desktop of course. Any problem with NetBeans ? Trying to kill 3 birds with one stone.

[android-developers] Re: Re: Packing data onto socket stream ?
If you're doing web dev and don't know about json, you're probably doing something wrong. Anyway, good luck with your odd approach. OK, OK, I shall look at it. May be it can simplify some of my tasks. You see there are always so many things to look into it that ends up looking a few things only. Java alone has so large a library it will probably take quite a while to get acquited with them, or at least read them very quickly just leave an impression. I have done a lot of C/C++, even then there are areas that I think are hair-raising. -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Re: Re: Re: Re: Packing data onto socket stream ?
If it's a trusted library such as apache (for example, the dynamically linked org.apache harmony system...) that's an entirely irrational fear. If it's a random jar you pull off a forum that's more understandable. If you want one, go find a trusted jar, make sure your download matches the checksum, and you'll be fine. Though I have to admit, the questions you're asking could easily be resolved if you set aside two or three days worth of time, read through basic socket tutorials outside of the context of your current questions, and came back to this issue. For what you're doing, this sounds like you're trying to implement something similar to IRC. IRC has messages, and also incorporates a mechanism for file transfer, if you look at the newer CTCP. However you won't be able to read and implement these (well, or your reduction to it) unless you have background socket programming knowledge, which you should get... I have done some pretty simple socket programing with C/C++. In this case, with pointers I have quite a free hand to encode my data using a scheme onto a memory buffer. At the receiving end once I get socket data into a memory buffer I can easily decode the data. As of now, I am just not certain how to encode my data onto a bytearray with java tools. For example given an integer, with C, just obtain a pointer to the integer then pack the 4 bytes one by one onto my buffer. In java, I think, as of now, I have to use the 'shift' operator and be careful with the sign bit. For you info, the file I/O and byte stream features in java are bewildering to a new comer. For one with a lot time they are no much of a problem. Thus advice help of gurus are essential to cut down learning time. -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Re: Packing data onto socket stream ?
Well, now it sounds like you're reinventing mime types..., but this isn't a horrible way to do it either I suppose. In either case what's giving you the difficulty? You can send the bytestream by doing a standard read() and write() across the socket, so this shouldn't be too bad.. Thanks. I am pretty new with Java (I have written no more than 2 programs, all from tutorial). I think there are pretty large gap in my knowledge. Only yesterday I discovered that a JTextArea object can be passed to another class; I have not come across this before. In C/C++ this is pretty normal with the use of pointer. Given a memory buffers (pointer), one can cast a length of bytes (from an offset) to a data type. Since you mention bytestream, I assume that I can use the format abytestream bb[i] to read the data. I shall test it out anyway. -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Re: Re: Packing data onto socket stream ?
These days, it's common to use text-based formats even if it's somewhat less efficient -- to simplify development, debugging and later, maintenance and enhancements. I have not thought about this; anyway I have been more active with PHP, javascript intepreted languages (before C/C++, occassional cursory look at Java). By the way you mean the current thinking is to convert binary data into ASCII representation ? I think hexadecimal notation (correct me if I am wrong), something like in an RTF file. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Re: Re: Re: Packing data onto socket stream ?
If you have a background with php and javascript you should already know about json. What are you trying to do? This sounds like something a simple webservice with a fileserver could easily do. I have heard about 'json' but never bother with it. Those web related things are done with PHP and javascript without 'json'. Recently while I was planning to FTP some files onto a webserver with java that I discovered java does not provide FTP features (quite a let-down really). Of course 3rd-party library like apache provides such a service, but I am a bit reluctant to use a 3rd-party tool, always fearing the possibilty of a back-door virus. It was only then I realised that a PHP script on a webserver would do the job. -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Packing data onto socket stream ?
I am sorry, I think this is not strictly an android question. From an android device, I want to a message to a PC via a socket. I am going to pack my data as follows: xxxThis is a greeting. where: xxx - message type (3 bytes, text) - integer, 4 bytes, length of text 'This is a greeting.' - the actual text The program at PC needs to decode the byte stream. I have done that in C/C++; not too sure with JAVA. I have searched for a while on net, now I have got headache (I am going to take a rest for a while). :-( :-( Java gurus please recommend.

xxxThis is a greeting. where: xxx - message type (3 bytes, text) - integer, 4 bytes, length of text 'This is a greeting.' - the actual text There's no reason to use the NDK for this, The standard Java socket API can be used for this easily: http://docs.oracle.com/javase/tutorial/networking/sockets/ I am not sure, for example, how to retrieve the integer portion (ie 4 bytes); any problem with Endian oddities ?

[android-developers] Re: Is this template in java
Not really. The confusion between Java generics and C++ templates causes more trouble than it explains things. When you come right down to it, the only thing in common is the angle-bracket syntax. It's very misleading to say that Java generics are like C++ templates. For that matter, it's pretty misleading to say that anything in Java is like its counterpart in C++. In Java pointers are called references and behave very differently from C++ pointers or references. Garbage collection works differently from destructors. The memory model is different. And so on. Not only that, but almost nothing from 1996 Java applies today. You don't use 'Vector' or 'Hashmap' any more, you have Swing (well, not for Android), a new threading model, generics, 'assert', for:each, enums, ... OMG! The list is HUGE what's missing from a 15-year-old reference. So much that it is essentially useless for a budding Android programmer. I did a little search on net, but did not see documents explaining the above. http://lmgtfy.com/?q=Java+tutorial Mine, I am reading a 15-year old book (from a friend) to catch up on Java. I think you have over-emphasized somewhat, it can't be that nothing applies.

Depends on your definition of working. It's not terminated, but the entire device may go to sleep, unless something wakes it up.

Keeping it awake for a duration you might need to process that data is up to you. Look up PowerManager. -- Kostya Thanks.
