I'm trying to upload video with Volley using a POST request but i don't know how create the stream of byte of a .mp4 video saved on my Android phone. Can someone help me?
Thank you.
Your approach is not the good one, I'd say. It could work but there are much simpler ways: why don't use a File and upload it to your server as a multipart/form request for instance: this answer is really good in this way.
It could be that it's not gonna work with big files and you won't be able to add a progress bar with this option.
I'm a big fan of Volley but it is pretty obvious that it hasn't been design for heavy file transfers and is focused on consuming a simple REST/JSON API. Therefore, I would recommend to switch library to something designed for your needs like this one (Android Async). It is, to me, much better FOR THAT PURPOSE (and if you need a webserver too!)
Hope it helps

I'm working on a prototype app to showcase an idea of mine -- so it need not be fully secure or gold standard, just needs to get the job done
I am wondering what the simplest option is to retrieve & parse, as well as publish JSON files from/to my Github repository. I am unsure which would be the easiest to implement. Right now, I see a few choices, but I am sure there are others you guys know of:
Using a Service class, which utilizes the Handler, AsyncTask, and HttpURLConnection classes (I've done a tutorial on Barry Burd's Android Application Development All-in-One For Dummies, 2nd Edition in which I made a weather app that utilized a service). I am still somewhat iffy with this.
A much easier, straightforward usage of HttpUrlConnection in this answer. I understand this fully.
A more complicated version in the developer docs. I do not really get this implementation either.
Also, the process can't freeze up the UI.
There is some cleaner and better approaches. You can use lots of libraries for this purpose.
Volley
Retrofit
These two are some of best libraries for calling webservise apis and I recommend Retrofit because it keeps your codes more clean and reusable.

I need to design a testing system which would not allow to use google. I mean that, theoretically, the user still can do it, but the purpose is to hinder this as much as possible.
I have an idea, but I don't know how good it is. I want the question in the database to be a simple text. And when we need to load it to the test, we convert it into a picture with a watermark. But the problem is that, theoretically, it still can be recognized. Google is able to convert the text on the image into the text and then search it as a text. Google is also able to recognize images despite some hue differences on them. Does anybody have proposals on that score? What would you do?
just use robots exclusion headers on the page to tell google not to store your page. or even robots.txt
As you say if it's human-readable, google will read it. Google has millions of slaves doing OCR for them (via Re-Captcha). but if you tell google to leave your site alone, it will.

Does anyone know of a way that I can either code a program (preferably in java), or use an existing program or API that will listen to the microphone and convert what you are saying into text and save to a file? I do not want it to have any fancy features, I just want to have a lightweight speech to text program that will use very little resources so that is will be fast and simple.
Thanks in advance for any help! ☻
Nilpmet,
I must have done this at least a dozen times using CMU's Sphinx, their continuous-speech, speaker-independent recognition system. Sphinx has a Java API which is pretty great.
Please let me know if you have any questions!
You can use Google's speech API, demonstrate here.
Here is a reverse engineering of this API, you can get your speech API key here.

What is the most efficient way to convert iOs mobile application into Android? A friend and I are working on an app and we would like to know what is our options?
Can we translate line by line the code? What can we do?
There is no conversion technique that you can just run your pre-existing IOS source code through and get Android source code
Unfortunately, that means you guys are going to have to decide if it is really worth the time and effort on porting.
Here are some resources for further reading:

Porting ios apps to android
You can write the codes by c language which are not related to UI, and call them by JNI on Android. If you did it, I think you can keep a same copy on IOS.

I am a student. I need to make a application. I have built the GUI. Now I need to know how to do it?
I have heard about sql server compact, but does it work together with j2me? If not, something to solve the problem?
It will be better if you can pass me a example. If you couldn't, not worry, I just to need to know a database program for mobile (with j2me).
Could it be possible without use a database program? For example, using a text file? Or any other storage mechanism.
Appreciate any help.
In j2me you can use RMS. But you can't handle with large data. Some Third party database's also available for j2me development. You can use that API's. Also refer this existing discussion on same in this forum. And look at database connection using j2me article.
