Why?
Adding a PNG images on camera would kill the purpose of having a camera at all. Camera preview needs to be showing the current image capturing in the device.
Did you mean to add a layer on the camera preview? If so, please read this thread: http://stackoverflow.com/questions/7466336/android-overlay-on-android-camera-preview[^]

I know the compiler does not care, but why do you write code with everthing left-justified? Do you find it easier to read? In addition, a lot of the code you've shown is completely irrelevant to the matter at hand (e.g., showPd, hidePD, onItemSelected, all of the import statements).
Why should the fragment display something? Have you stepped through the code (using the debugger) to see if it is executing the way you'd expect?

I'm trying to display gif images on Android. This is my code to display a.gif :
WebView wView = new WebView(this);
wView.loadUrl("android.resource://" + getPackageName() + "/" + R.drawable.a);
setContentView(wView);
But I get this :
The webpage at android.resource://com.example.mypc.myapp/2497475928917
could not be loaded because :
net::ERR_UNKNOWN_URL_SCHEME
My gif files are in drawable and raw folder under res folder. Can you tell me how to give paths of gifs correctly? Thanks in advance.

Animated GIF, or just a single image? Lots of suggestions here.

This should probably be:
wView.loadUrl("file:///android_asset/a.gif");

Is that better than using their SDK?

Did you check the docs?

I am going on a project, something like the two apps that I mentioned in the title. And I can seldom found how such application work with the search engine, so here I come. 
I've asked the question in the quick answers, but the questions are too board for quick answers, so I ask the questions again here.
"etude" or "auto flip" are the applications for one who plays piano with no need to flip the music sheet manually.
Here are some questions that I wish you can give me a help;
1. How to display the music sheet, with which format?
2. How can I compare the information of music sheet with the real-time voice, and find out the pinpoint to flip the music sheet?
3. How can the voice with multiple notes at the same time be recognized? This question is optional for now. I think I should finish recognizing one note in a time first.
And, my chaotic thought will be given in the following, if you don't want you thought to be blocked, you should not continue reading it.
(...Think...)
(...Think once)
(...Think twice)
Ok, my chaotic thought now is that using MIDI to format the music sheet, and then convert the real-time voice to some format, like frequency space, whatever; and then compare it with the MIDI, thought I don't know how, this is the problem. And I think it should have a better way to do. Thanks for watching all of this!!

Firstly, again, thank you for your answering. But, it is hard to say your answer has answered my question, right? And I thought, you said that my topic was too large to suit for quick question, so I moved it here, I don't think I has offended anybody. But anyway, I am new here, I haven't learn the rules yet, so maybe I did it wrongly.

Your question is far too large to be answered here. You are asking someone to explain how two random applications work. You cannot realistically expect such information from a technical forum. As I expalined before, you need to go and do the research for yourself. When you have specific questions come back here and people will try to help you. In the meantime you should also read http://www.codeproject.com/Messages/3137514/Forum-Guidelines-PLEASE-READ.aspx[^].

I was looking for suggestion what would be best approach in below scenario:
1. Have 3 spinners ("districts", "city", "shops").
2. Once user select an item from "districts" spinner, "city" spinner is populated and once city is selected "shops" could be selected. Now I have used a subclass of AsyncTask class to populate district spinner.
For populating other spinners "city" and "Shops", is writing separate subclass dedicated to each sinner the only option and update each spinners (which is a View) in each class's onPostExecute() method ? Is there any way to use a single subclass of AyncTask and use that for populating all "cascaded" spinner ? What could be best approach in such scenario.
Thanks,
Arindam D Tewary

You could use a single subclass and just pass it the id of the spinner and the list of items to populate it.
|
|
|
|
|
Yah, Thanks Richard, I could figure out this. I noticed that the first param is an array of argument(varargs) in execute method in AsyncTask and that is something I could use for this purpose. I could just pass an indicator string just to differentiate and used switch-case in onPostExecution method and I could get it going today.
I will check with passing view id would help me better.
Thanks,
Arindam D Tewary

Hello. I am in the design process in creating a video chat application. I am trying to come up with the best route for the video transmission..being new to the mobile world I am wondering if there needs to be a 'middle-man' that is in charge of routing the data?
For instance, should I have each client hit a webservice that would be in charge of sending the data to the other client? Should I just have the clients connect directly to each other (if possible) and by pass a webservice?
Can anyone answer how apps like Periscope handles the transmission of its video?
Thank you.
