  • Temporary animations

    - by Max
    I've been trying to find a tutorial on how to best make animations in Android. I already have some animations for my enemies and my character that are controlled by rectangles and changing rectangleframe between updates using a picture like this: When I'm shooting my enemies they lose HP, and when their HP == 0 they get removed. aslong as im using an arrayList (which I do for all enemies and bullets) I'm fine, since I can just use list.remove(i). But when I'm on a boss-level and the Boss's HP == 0, I want to remove him and play an animation of an explosion of stars before the "End-screen". Is there a preferred way to do temporary animations like this? If you can give me an example or redirect me to a tutorial, I'd be really grateful!

  • Separate parts of a game engine [on hold]

    - by user272716
    I'm pretty new in developing videogames. By now I only used SDL with C/C++ to create games. I'm currently learning OpenGL and I realized that to be fluid and easy to maintain the code must be logically separated. Since I want to use OpenGLES on iOS and Android I was wondering how the engine must be imagined in a technical way, some questions came up: Do I have to separate input/update functions from draw functions in different threads? Is there only one proper way to think a game engine/loop? What kind of assets should I use to create a 3D game using openGl ES to get better performance?

  • Play music from computer on phone, over WiFi?

    - by wim
    Wasn't sure whether to ask on here on on android.stackexchange.com ... but I want to play music which is on my desktop machine through my phone. The music is coming from ext4 partition which I am happy to share on the LAN. It should use WiFi not bluetooth (because I hope to use the bluetooth interface for other things, simultaneously). Is it possible and what do I need to setup on the desktop (on Ubuntu 12.04) and/or my phone (galaxy nexus)? edit: Just to clarify, I want the music to be playing from the phone, not through the desktop's speakers.

  • How to calculate shot angle and velocity to hit a moving target?

    - by Guen
    I am developing a 2D Android game and I am making an aiming algorithm for AI projectiles to hit enemies either following a path, or free moving. At the moment it just calculates where the target will be after a distance and fires a projectile to meet it at that distance. Of course this means varying the projectile speed to meet the target. Does anyone have any tips for a simple-ish algorithm (optimal-ish) to calculate when the projectile needs to fire and where it needs to aim if it can only travel at a constant velocity? Say the projectile goes twice the speed of the target? The only way I can think of involves searching and seems quite large.

  • Can I install 12.10 on Ainol Novo7 Venus?

    - by Jens Grünwald
    Is it possible to install Ubuntu on my Ainol Novo7 Venus? I don't want any tablet-version of ubuntu, because I like ubuntu how it is and think there is no need for a tablet-version (I know there is no tablet-version, but many questions after it). So I want to install full desktop-ubuntu 12.10 with unity and everything, but I want a dual-boot with my existing android installation. Is that possible? If so, how? Is 16gb enough for ubuntu or should I buy an extra sd-card for it?

  • Activity and View [closed]

    - by CYB
    Now, I'm going to create an app that can reserve something. There's three function like menu, reserve, and search. However, I don't know that I should create them as three Activities or just use three views as the function. I want to switch to other function by onclicklistener. Below is my onClickListener, private OnClickListener listener = new OnClickListener(){ public void onClick(View v) { switch(v.getId()){ case R.id.fuiButton1: break; case R.id.fuiButton2: break; case R.id.fuiButton3: break; } } }; Which is the best choice ?

  • SPP Socket createRfcommSocketToServiceRecord will not connect

    - by philDev
    Hello, I want to use Android 2.1 to connect to an external Bluetooth device, wich is offering an SPP port to me. In this case it is an external GPS unit. When I'm trying to connect I can't connect an established socket while being in the "client" mode. Then if I try to set up a socket (being in the server role), to RECEIVE text from my PC everything works just fine. The Computer can connect as the client to the Socket on the Phone via SPP using the SSP UUID or some random UUID. So the Problem is not that I'm using the wrong UUID. But the other way around (e.g. calling connect on the established client socket) createRfcommSocketToServiceRecord(UUID uuid)) just doesn't work. Sadly I don't have the time to inspect the problem further. It would be greate If somebody could point me the right way. In the following part of the Logfile has to be the Problem. Greets PhilDev P.S. I'm going to be present during the Office hours. Here the log file: 03-21 03:10:52.020: DEBUG/BluetoothSocket.cpp(4643): initSocketFromFdNative 03-21 03:10:52.025: DEBUG/BluetoothSocket(4643): connect 03-21 03:10:52.025: DEBUG/BluetoothSocket(4643): doSdp 03-21 03:10:52.050: DEBUG/ADAPTER(2132): create_device(01:00:00:7F:B5:B3) 03-21 03:10:52.050: DEBUG/ADAPTER(2132): adapter_create_device(01:00:00:7F:B5:B3) 03-21 03:10:52.055: DEBUG/DEVICE(2132): Creating device [address = 01:00:00:7F:B5:B3] /org/bluez/2132/hci0/dev_01_00_00_7F_B5_B3 [name = ] 03-21 03:10:52.055: DEBUG/DEVICE(2132): btd_device_ref(0x10c18): ref=1 03-21 03:10:52.065: INFO/BluetoothEventLoop.cpp(1914): event_filter: Received signal org.bluez.Adapter:DeviceCreated from /org/bluez/2132/hci0 03-21 03:10:52.065: INFO/BluetoothService.cpp(1914): ...

  • C# Menu Toolstrip Get Status

    - by Yeti
    So I have a project where there is some automatic initialization going on through some classes that are created automatically as global variables (deah they are static instances). At a point inside this (it has no relation with the C# GUI for the user, so it isn't derived from any C# class) I need to see if a flag is set or not. I use toolstrip menu with checked and unchecked status in order to set or unset the flag. The problem is that I have difficulties to see if the flag is checked or not from this static class. My class is inside a different project/namespace and a DLL is created what later is linked to the GUI of the application. The GUI depends from this Manager class so making the Manager class to depend from the GUI is not an option. Nevertheless, I should be able to see its state knowing its name or through some other means. I have tried the following: if(Application.OpenForms[1].Owner.Controls["useLocalImageForInitToolStripMenuItem"].Enabled) { }; Now the problem is that on the upper code snippet I get a nasty error. So how do I do this?

  • ASP.Net menu databinding encoding problem

    - by WtFudgE
    Hi, I have a menu where I bind data through: XmlDataSource xmlData = new XmlDataSource(); xmlData.DataFile = String.Format(@"{0}{1}\Navigation.xml", getXmlPath(), getLanguage()); xmlData.XPath = @"/Items/Item"; TopNavigation.DataSource = xmlData; TopNavigation.DataBind(); The problem is when my xml has special characters, since I use a lot of french words. As an alternative I tried using a stream instead and using encoding to get the special characters, with the following code: StreamReader strm = new StreamReader(String.Format(@"{0}{1}\Navigation.xml", getXmlPath(), getLanguage()), Encoding.GetEncoding(1254)); XmlDocument xDoc = new XmlDocument(); xDoc.Load(strm); XmlDataSource xmlData = new XmlDataSource(); xmlData.ID = "TopNav"; xmlData.Data = xDoc.InnerXml; xmlData.XPath = @"/Items/Item"; TopNavigation.Items.Clear(); TopNavigation.DataSource = xmlData; TopNavigation.DataBind(); The problem I'm having now is that my data doesn't refresh when I change the path where the stream gets read. When I skip through the code it does, but not on my page. So the thing is either, how do I get the data te be refreshed? Or (which is actually preferred) how do I get the encoding right in the first piece of code? Help is highly apreciated!

  • CSS animated menu

    - by Andrea
    I am trying to obtain something similar to the "share this on..." menu here but I don't quite understand how they are doing this, even after a look at their CSS. I refer to the fact that the images show up on hover. My first attempt would be something like <div id="share_on"> <ul> <li><a href="#"><img src="shareon-digg.png" /></a></li> <li><a href="#"><img src="shareon-reddit.png" /></a></li> ... <li><a href="#"><img src="shareon-stumbleupon.png" /></a></li> </ul> </div> and the CSS: #share_on {overflow: hidden} #share_on ul {margin-bottom: -16px} #share_on li {display: inline} #share_on li:hover {margin-top: -16px} Of course this does not work, which is why I am asking here. In the inactive state, only half of the icon shows up, which is the expected behaviour. But on hover, nothing changes. I also have tried some variations, like #share_on li:hover {margin-bottom: 16px} or #share_on li:hover {padding-bottom: 16px} but none of these works. Any ideas?

  • Context menu event handling error - CS1061

    - by MrTemp
    I am still new to c# and wpf This program is a clock with different view and I would like to use the context menu to change between view, but the error says that there is no definition or extension method for the events. Right now I have the event I'm working on popping up a MessageBox just so I know it has run, but I cannot get it to compile. public partial class MainWindow : NavigationWindow { public MainWindow() { //InitializeComponent(); } public void AnalogMenu_Click(object sender, RoutedEventArgs e) { /*AnalogClock analog = new AnalogClock(); this.NavigationService.Navigate(analog);*/ } public void DigitalMenu_Click(object sender, RoutedEventArgs e) { MessageBox.Show("Digital Clicked"); /*DigitalClock digital = new DigitalClock(); this.NavigationService.Navigate(digital);*/ } public void BinaryMenu_Click(object sender, RoutedEventArgs e) { /*BinaryClock binary = new BinaryClock(); this.NavigationService.Navigate(binary);*/ } } and the xaml call if you want it <NavigationWindow.ContextMenu> <ContextMenu Name="ClockMenu" > <MenuItem Name="ToAnalog" Header="To Analog" ToolTip="Changes to an analog clock"/> <MenuItem Name="ToDigital" Header="To Digital" ToolTip="Changes to a digital clock" Click="DigitalMenu_Click" /> <MenuItem Name="ToBinary" Header="To Binary" ToolTip="Changes to a binary clock"/> </ContextMenu> </NavigationWindow.ContextMenu>

  • My PreferenceActivity does not show up, even though it is in my manifest file

    So I am modifying the Cube live wallpaper example. I have a class that extends PreferenceActivity, and I added the Activity in my manifest file. I keep getting ActivityNotFoundExceptions. Here is my preference class : public class MySettingsActivity extends PreferenceActivity implements SharedPreferences.OnSharedPreferenceChangeListener { @Override protected void onCreate(Bundle bundle) { super.onCreate(bundle); getPreferenceManager().setSharedPreferencesName( ParticleCandy.SHARED_PREFS_NAME); addPreferencesFromResource(R.xml.settings); getPreferenceManager().getSharedPreferences().registerOnSharedPreferenceChangeListener( this); } @Override protected void onResume() { super.onResume(); } @Override protected void onDestroy() { getPreferenceManager().getSharedPreferences().unregisterOnSharedPreferenceChangeListener( this); super.onDestroy(); } public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) { } } And here is my manifest file <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.pixel.theory.wallpapers.mywallpaper" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <service android:label="@string/app_name" android:name="MyWallpaper" android:permission="android.permission.BIND_WALLPAPER" > <intent-filter> <action android:name="android.service.wallpaper.WallpaperService"> </action> </application> <uses-sdk android:minSdkVersion="7" /> <uses-feature android:name="android.software.live_wallpaper" /> </manifest> Any ideas why my preferences activity doesn't get read in from the manifest?

  • Hey Guy , I want ot streaming video by using VideView class . Can anyone tell me what format is it s

    - by eddyxd
    Hi , I am the newbie of android, but i hava seen the tutorial and implement some simple applications. The question i met is that I am tring to stream some video from my server to android, but the android VideoView class just plays the audition sololy without "image"@@!~ Here is my setting and android code : 1. android core code: mVideoView01.setVideoURI(Uri.parse("rtsp://192.168.16.1:8080/test.sdp")); mVideoView01.start(); 2. my streaming server is VLC and the command is: vlc -vvv d:\nobody.mp4 --sout=#transcode{vcodec=h264,width=320,hegiht=240}:rtp{dst=192.168.16.1,port=4444,sdp=rtsp://192.168.16.1:8080/test.sdp} ps: My ip is got from DHCP but I have checked it really can be connected(Android could play audition after all) ps2: I haved trid to stream some video from "http://www.americafree.tv/" and the playing is good!!@@ So I guess that the problem maybe is caused by streaming Video format, but I have almost tried every figument option form VLC, and it still don't workQQ. So Have anyone done the same test as me can give me some advice?? Thanks a lot!!!!! by eddy

  • Symfony + JQueryUI Tabs navigation menu question

    - by Andy Poquette
    I'm trying to use the tabs purely as a navigational menu, loading my pages in the tabs, but being able to bookmark said tabs, and have the address bar correspond with the action I'm executing. So here is my simple nav partial: <div id='tabs'> <ul> <li id='home'><a href="<?php echo url_for('post/index') ?>" title="Home">Home</a></li> <li id='test'><a href="<?php echo url_for('post/test') ?>" title="Test">Test</a></li> </ul> </div> And the simple tabs intializer: $(document).ready(function() { $('#tabs').tabs({spinner: '' }); }); My layout just displays $sf_content. I want to display the content for the action I'm executing (currently home or test) in the tab, via ajax, and have the tab be bookmarkable. I've googled this like 4000 times and I can't find an example of what I'm trying to do. If anyone has a resource they know of, I can look it up, or if you can help, I would greatly appreciate it. Thank you in advance.

  • identifying id of listitem for contextmenu

    - by martinjd
    I have a View that extends Activity. A ListView will display a number of listitems. When the user long clicks I would like to present them with a contextmenu allowing them to select edit, delete etc... and then identify the listitem that was selected as the item to perform the action on. In onCreate I have: listView.setAdapter(adapter); listView.setOnItemClickListener(onListClick); listView.setOnItemLongClickListener(onListLongClick); registerForContextMenu(listView); I have a method onCreateContextMenu @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); menu.setHeaderTitle("Context Menu"); menu.add(0, v.getId(), 0, "Edit"); menu.add(0, v.getId(), 0, "Delete"); } and also onContextItemSelected @Override public boolean onContextItemSelected(MenuItem item) { if (item.getTitle() == "Edit") { // edit action } else if (item.getTitle() == "Delete") { // delete action } else { return false; } return true; } I am not sure where to go from here to get the correct row/listitem.

  • Can't seem to load a webview from xml, why?

    - by Bilthon
    Well, I'm trying to follow the tutorial from http://rapidandroid.org/wiki/Graphing. But I found a problem just in the first part of it. I'll describe the problem here, I just cannot understand how this could be wrong, it's pretty simple stuff. What am I doing wrong here? First I created a xml file called statistics.xml, in it among other things I put this code: <WebView android:id="@+id/webview" android:layout_height="fill_parent" android:layout_width="fill_parent"/> Now in the activity that is supposed to display this webview I'm doing this: public class DisplayStatistics extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); WebView wv = (WebView) findViewById(R.id.webview); The problem arises here, as I seem to be getting null for wv whenever I test for it. Which means of course that findViewById(R.id.webview) couldn't find the view. But again, what am I doing wrong?? Of course I know I could also instantiate the webview directly from code without the need to specify it from the xml, but I was just wondering what was wrong about this way of doing it. Just in case I also added the following line in my android manifest file: <uses-permission android:name="android.permission.INTERNET" /> I'm not really sure if it's necessary for displaying the webview (I think not) but I just put it there to see if that was the problem, and it turned out it isn't. Thanks Nelson

    - by Nick
    Hello All, First question... I'm having trouble getting ANY of the Drop down menu/Input Select's to appear with size 18 font in Safari. Works fine in FF. Code: <form class="form"> <select name="make"> <option value="0"> All</option> </select> </form> Css: .form input{ font-size:18px; margin-bottom:0px; } Any ideas? Can view live at [http://www.motolistr.com][1] Best, Nick EDIT 1: Thanks for the quick reply. I added a style to the select itself to avoid confusion.

  • How to simplify my country select menu PHP/mysql

    - by user342391
    I have a select menu that displays countries. It looks at the DB and judging by the value in the db shows the option as selected. Is there a simpler way off doing this than: if ($country == 'AG') {echo '<option value="AG" selected="selected">Antigua</option>';} else {echo '<option value="AG">Antigua</option>';}; if ($country == 'AR') {echo '<option value="AR" selected="selected">Argentina</option>';} else {echo '<option value="AR">Argentina</option>';}; if ($country == 'AM') {echo '<option value="AM" selected="selected">Armenia</option>';} else {echo '<option value="AM">Armenia</option>';}; if ($country == 'AW') {echo '<option value="AW" selected="selected">Aruba</option>';} else {echo '<option value="AW">Aruba</option>';}; if ($country == 'AU') {echo '<option value="AU" selected="selected">Australia</option>';} else {echo '<option value="AU">Australia</option >';}; if ($country == 'AT') {echo '<option value="AT" selected="selected">Austria</option>';} else {echo '<option value="AT">Austria</option>';}; if ($country == 'AZ') {echo '<option value="AZ" selected="selected">Azerbaijan</option>';} else {echo '<option value="AZ">Azerbaijan</option>';}; if ($country == 'BS') {echo '<option value="BS" selected="selected">Bahamas</option>';} else {echo '<option value="BS">Bahamas</option>';}; if ($country == 'BH') {echo '<option value="BH" selected="selected">Bahrain</option>';} else {echo '<option value="BH">Bahrain</option>';}; There are a lot of countries and doing this would be madness wouldn't it????

  • How to draw some lines in a view element defined in the xml layout

    - by Nils
    Hello, I have problems drawing some simple lines in a view object (Android programming). First I created the layout with the view element(kind of painting area) in it (XML file). [...] < View android:id="@+id/viewmap" android:layout_width="572px" android:layout_height="359px" android:layout_x="26px" android:layout_y="27px" [...] ... and tried then to access it to draw some lines. Unfortunately the program is running and other UI elements like buttons are displayed, but I can't see the drawings. What's wrong ? [...] viewmap = (View) findViewById(R.id.viewmap); Canvas canvas = new Canvas(); viewmap.draw(canvas); Paint p = new Paint(); p.setColor(Color.BLUE); p.setStyle(Paint.Style.STROKE); canvas.drawColor(Color.WHITE); p.setColor(Color.BLUE); canvas.drawLine(4, 4, 29, 5, p); p.setColor(Color.RED); viewmap.draw(canvas); [...] Thanks for help :) !
