  • Can't correctly stream x264 video to mobile via RTSP

    - by Andrew
    Hello! I'm trying to stream video compressed with x264 and NeroAAC and hinted with MP4Box. When i'm playing it with VLC player streaming works fine, as expected. When i'm trying to open URL with my HTC Hero, it switches to player mode, then starts "loading video" animation, then after some time it shows "unable to connect to server". Sample movies provided with DSS streamed fine regardless bitrate. I tried few encoding options, but always the same result. I suspect nocabac and level=11 but it didn't changed nothing. Is there some more specific encoding options for such type? Thank You!

  • Is it possible to change the pane locations in Chrome Developer Tools?

    - by T.J. Crowder
    When debugging browser-based apps using Google Chrome's Developer Tools, is there a way to change the locations of the various panes? E.g., the Watch Expressions, the Call Stack, the code pane, etc.? The defaults are okay (console at bottom, code pane upper left, a column of Watch Expressions, Call Stack, Scope Vars, etc. in the upper right), but I'd rather swap things around a bit of it's possible. There doesn't seem to be anything to grab (other than for sizing) and I haven't found a way in my searching so far, but there are (still) some things about Chrome's options that aren't ... well-advertised in the UI, shall we say :-), especially around developer tools.

  • Write contents of custom View to large Image file on SD card

    - by JFortney
    I have a class that extends View. I override the onDraw method and allow the user to draw on the screen. I am at the point where I want to save this view as an image. I Can use buildDrawingCache and getDrawingCache to create a bitmap that I can write to the SD card. However, the image is not good quality at a large size, it has jagged edges. Since I have a View and I use Paths I can transform all by drawing to a bigger size. I just don't know how to make the Canvas bigger so when I call getDrawingCache it doesn't crop all the paths I am just transformed. What is happening is I transform all my paths but when I write the Bitmap to file I am only getting the "viewport" of the actual screen size. I want something much bigger. Any help in the right direction would be greatly appreciated. I have been reading the docs and books and am at a loss. Thanks Jon

  • Is it possible to get last modified date from an assets file?

    - by Nathan Fig
    Hi, all Bizarre question: is it possible to get the last modified date of a file in the assets folder, or would that be pointless and impossible? I ask because I'm copying a read-only database out of there into the data folder on application start up, but would rather only perform the copy if the existing file is older than the one stored in the assets folder (or if the file doesn't exist). If that's not possible, anyone know of a better convention? I can post that in a separate question if needed. TIA!

  • Soundpool sample not ready

    - by SteD
    I have a .wav file that I'd like to use across my game, currently I am loading the sound in onCreate() of each activity in the game. soundCount = soundpool.load(this,R.raw.count, 1); The sound will be played once the activity starts. soundpool.play(soundCount, 0.9f, 0.9f, 1, -1, 1f); Problem is at times I will hit the error "sample x not ready". Is it possible to load the .wav file once upon starting the game and keep it in memory and use it later across the game? Or is it possible to wait for 1-2 seconds for the sound to load finish?

  • Show context menu when link is long pressed in TextView

    - by Al
    I have a TextView with its MovementMethod set to LinkMovementMethod. Text added to the TextView is a combination of normal text and URLs. For URLs, I would like to offer a context menu when the URL is long pressed for doing things such as copying the address. I've had a look at the source for LinkMovementMethod but it doesn't seem to have any long pressed related code I could override. Any ideas on how to go around achieving this?

  • In Google Glass, Menu Items are not shown after XE 17.2 Update, any Solutions?

    - by Amalan Dhananjayan
    This worked when the Glass in on XE12, I have opened the solution after about 2 Months and now with XE17 the menu items are not shown when tapped on the Live card, instead the live card is disappearing. I have updated the GDK, I have changed the code to support the latest GDK sneak peek version 2 changes according to this (https://developers.google.com/glass/release-notes#xe12) This is the code public class MenuActivity extends Activity { private static final String TAG = MenuActivity.class.getSimpleName(); private VisionService.VisionBinder mVisionService; private ServiceConnection mConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { if (service instanceof VisionService.VisionBinder) { mVisionService = (VisionService.VisionBinder) service; openOptionsMenu(); } // No need to keep the service bound. unbindService(this); } @Override public void onServiceDisconnected(ComponentName name) { } }; private boolean mResumed; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); bindService(new Intent(this, VisionService.class), mConnection, 0); } @Override protected void onResume() { super.onResume(); mResumed = true; openOptionsMenu(); } @Override protected void onPause() { super.onPause(); mResumed = false; } @Override public void openOptionsMenu() { if (mResumed && mConnection != null) { super.openOptionsMenu(); } } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { int id = item.getItemId(); if (id == R.id.action_send) { mVisionService.requestWorkOrderCard(); finish(); return true; } else if (id == R.id.action_refresh) { mVisionService.requestTopWorkOrders(); finish(); return true; } else if (id == R.id.action_finish) { stopService(new Intent(this, VisionService.class)); finish(); return true; } else { return super.onOptionsItemSelected(item); } } @Override public void onOptionsMenuClosed(Menu menu) { super.onOptionsMenuClosed(menu); } } It would be great if any body could help on this.

  • Starting Frame-By-Frame Animation

    - by OceanBlue
    Hi, I have a basic question about starting a frame-by-frame animation. When I call the AnimationDrawable.start() method from my code directly, it doesn't seem to work. public void onCreate(Bundle savedInstanceState) { ... mAnimation.start(); ... } But if I put this line inside the onClick() callback method of a button, pressing the buton starts the animation. Why doesn't this line work in the code? Thanks!

  • ImageAdapter and ListView (java.lang.OutOfMemoryError: bitmap size exceeds VM budget)

    - by theDude
    Hi, I'm using ListView to display images which I provide through an ImageAdapter class. it works great on my device (and on many other devices which I tested it on), but somehow when I'm using the emulator and I'm long-pressing the up/down button - I'm getting an outOfMemory error after 10-15 seconds. I tried clearing cache, canceling cache, etc. - nothing helped. I know this crash is pretty rare (i couldn't reproduced it on any "real" device), but I can see on DDMS that "GC freed" are getting bigger during that long press and I can't find a way to clear them. Any help will be appreciated, Tnx.

  • How to calculate the time difference between two time fields , with respect to the date changes

    - by Tiru
    I want to calculate the time difference.I have three EditTexts , I want to input the times in the first two edittexts in HH:MM format. And then calculate the time difference and the result will show on third edittext field in same format. If the date changes, the time difference will calculate according that, i.e If first time = 23:00 and second time = 01:00 then, the time difference = 02:00 hours public class TimeCalculate extends Activity { private String mBlock; private String mBlockoff; private String mBlockon ; // String mHours, mMinutes; Date date1, date2; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); EditText blockoff = (EditText) findViewById(R.id.blockoff); mBlockoff = blockoff.getText().toString(); EditText blockon = (EditText) findViewById(R.id.blockon); mBlockon = blockon.getText().toString(); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("hh:mm"); try { date1 = simpleDateFormat.parse(mBlockoff); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { date2 = simpleDateFormat.parse(mBlockon); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } mBlock = getDifference(date1, date2); EditText block = (EditText) findViewById(R.id.block); block.setText(mBlock.toString()); } public static String getDifference(Date startTime, Date endTime) { if (startTime == null) return "corrupted"; Calendar startDateTime = Calendar.getInstance(); startDateTime.setTime(startTime); Calendar endDateTime = Calendar.getInstance(); endDateTime.setTime(endTime); long milliseconds1 = startDateTime.getTimeInMillis(); long milliseconds2 = endDateTime.getTimeInMillis(); long diff = milliseconds2 - milliseconds1; /*int hours = (int)diff / (60 * 60 * 1000); int minutes = (int) (diff / (60 * 1000)); minutes = minutes - 60 * hours; long seconds = diff / (1000); */ //timeDiff = DateUtils.formatElapsedTime(seconds); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:MM"); Date date = new Date(diff); return simpleDateFormat.format(date); } } I executed this code ,but gives error as Source not found.I think error at getDifference method.Please give any other logic

  • Is displayMetrix xdpi and ydpi accurate?

    - by oddvark
    Can the xdpi and ydpi settings be relied upon to accurately represent the physical pixels in once inch of screen space? I need this to be accurate for some display code I'm writing. I realize the documention says that this is the case, but I need to know if individual handsets get this right MOST OF THE TIME. I know I can alternately use "densitiy" which will give me 120, 160, 240 steps of DPI, but an exact dpi would be much better. Thanks!

  • How to fix button size?

    - by rob
    I am using three buttons along with the list view.These three buttons are added to the layout using the TableRow.The first button takes more space on content, so the other two becomes smaller in size than first one. When the application runs, it doesn't even show the two other buttons. How can I make the size of three buttons equal and display all of them when application runs?

  • How to keep activity on Force Close?

    - by SushiRoll
    I have this piece of code that's really prone to errors so I wrapped it with try{}catch statement. I don't want to go back to the previous activity, I just want it to stay on the current activity so that the user can edit whatever is wrong with them. How do I implement this? try{ orgi.insertOrThrow(tableName, null, values); Toast.makeText(this, "You have successfully created a new profile!", 2).show(); gotoProfileList(); Log.e(getClass().getSimpleName(),"Successfully added to database"); }catch(SQLiteException se){ Log.e(getClass().getSimpleName(), "Database connection failed!" + se); //Stay in this activity... }finally{ if (orgi != null){ orgi.close(); } } Forget it, I was able to solve my own problem by showing up an alertDialog that tells the user about the error. Thanks anyways. :) try{ orgi.insertOrThrow(tableName, null, values); Toast.makeText(this, "You have successfully created a new profile!", 2).show(); gotoProfileList(); Log.e(getClass().getSimpleName(),"Successfully added to database"); }catch(SQLiteException se){ Log.e(getClass().getSimpleName(), "Database connection failed!" + se); displayError(); //stayInThisActivity(); }finally{ if (orgi != null){ orgi.close(); } public void displayError(){ AlertDialog.Builder error = new AlertDialog.Builder(this); error.setMessage("That profile name already exists, try another one.").setCancelable(false).setPositiveButton("Yes",new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.cancel(); } }); AlertDialog alert = error.create(); alert.setTitle("Error"); alert.show(); }

  • What benefits can Java developer have from moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse on it, so there will be no big difference. Guys, who use Java on *NIX, could you please give me some real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • Have you considered doing revenue sharing to fund development of a mobile app? How would you do it?

    - by Brennan
    I am looking to build multiple mobile apps which leverage existing content and resources by enabling these mobile apps with web services. I will duplication much of the same features which are also in place and add more features that are possible on a mobile device like address book, maps and calendar integration to make the service much more useful. To fund these projects I see that I have 2 options. First I could simply quote them for the project based on my hourly rate and the estimate in hours that I will take the to complete the job. That may be a high number. The second option would be to do shared revenue with ads placed in the app. I could then take a percentage of any revenue that is generated from the app. There is also a hybrid where I might charge for a percentage of the estimated quote and then take a percentage of the revenue sharing. So my question is how much should I propose for the revenue sharing? Should it be 30%? Or maybe I should make it 70% up to a point that a certain dollar amount is reached? And should the revenue sharing agreement be for 12 months, 24 months or more? Should I include in the proposal an agreement that they will help promote this app with their content and resources? Ultimately this system will benefit both sides because it extends their reach into the mobile space instead of where they are currently with just print and web. I have tried to find some examples with a few Google searches but I keep hitting content about the Google and Apple revenue sharing models. I would like to get some solid examples that are working to compare against so that my proposal do build these apps is not completely off base.
