I am running my application in the emulator using a high density skin (like WVGA800). However the ressources in my application are loaded from the drawable- mdpi folder instead of drawable-hdpi ... what else should I do so that android use the correct folder ?

When the user taps the search button I animate between the two layouts. The problem is that the layouts are different sizes and I can't figure out how to make them take up the same amount of space. Here's what I mean. p.s. forgive the bad art, they are just place holders ;)
View 1 Replies View RelatedI am trying to do something similar to that of the android lock screen pattern. I have a class that extends a view that I create multiple instances of. These appear on the screen all at once.
I need to be able to click on them individually and have each one turn green individually, however only one on touch listener is listening at once and it belongs to the last dot which appeared, so if I click anywhere on the screen the last appeared dot turns green no matter where I click.
Here is the code for my dot class:

In the code I called newdotdraw multiple times.

CODEE:..........
where do I put this in my code, do I have to create a new class for it, or can I have it in an inner class, or does it not need a class at all?! I have a set up similar to Lunar Lander which comprises of two files, one of which is a thread that handles pretty much all the physics and drawing of the game. The other file begins the thread and saveInstanceState method. Furthermore, what type is mLibrary?! I cannot find out anywhere! I imagine I will put the OnGesturePerformed method in my thread as this is where I handle all keyUp and Down events.
I am required to work on an application which is be deployed on devices running Android 1.5. The application is supposed to maintain a connection with a server and regularly poll it for new data. The server will notify the client of new data following which the client will connect to the server and download the data.I know that ideally a push based approach will be more conducive here given that we are to run this on a mobile platform. Also, from Android2.2 there is going to be support for C2DM(Cloud to Cloud device Messaging) but as already mentioned this application is for devices running Android1.5.Implementation: I was thinking of using AlarmManager which would Broadcast Intents periodically(poll interval), The Broadcast receiver will then try to connect to the remote server and make data changed check. If the server has an update, the thread will connect to the remote server and download the data from the server.
Problem and Issues: 1. Is this the right way to approach the problem? 2. Is AlarmManager reliable? Would it remember Alarms after a device boot? (I think it does) 3. How do I ensure that battery usage is kept at minimum.(I have heard something about using "keep-alive" to sustain the session for longer time..what is this legend?) 4. What are other things that I need to consider? I am sure I must be missing lots of things here.
Does anyone have any good references for designing and implementing an idea I have for an android application. My idea is for an application that stores information and reviews about a specific location and presents this information to user.I have gone through all the tutorials and have been reading up on anything and everything about android. Now I am ready to challenge myself with my first app.

View 2 Replies View RelatedI have some design questions that I want to discuss with people interested in helping me. I am planning to develop a simple VoIP program that allows two Android phones in the same network to use VoIP. My goal is simply to capture sound, send the data with UDP, receive UDP data and play sound.My current design is to have 2 threads: one captures the microphone and sends the data; the other one receives bytes and plays them.I was starting to implement that using MediaPlayer and MediaRecorder. The issue that came up is how do I record and play sound? By that, I would like to know if I need to use a file, although that seems slow, or if there is anyway to have the recording automatically sent to my UDP socket please?Basically, I wonder if I have to record to a file, then to be able to play it, or if I could just pass a socket (for recording and playing).
View 1 Replies View RelatedI'm writing an application where real-time knowledge of the GPS state is critical to convey to the user. I request GPS updates at 1000 ms intervals -- when I haven't received another update 1500 ms past the most recent update, I want to display a yellow icon, and 5000 ms after the most recent update I want to display a red icon. Currently, I'm doing it like this: private CountDownTimer gpstimeout; public void onLocationChanged(Location location) { if (gpstimeout != null) gpstimeout.cancel(); gpstimeout = new CountDownTimer(5000, 1500) { public void onTick(long m) { setYellow(); } public void onFinish() { setRed(); } }; gpstimeout.start(); }

I am creating a small calendar control that will be part of an application that runs on a larger-than-phone-sized screen. The calendar will simply display the current month and allow users to touch-select a day with an iPhone keyboard style popup bubble indicating which day is chosen.
The problem is that in order to do it with buttons would require 42 tiny buttons, which would probably be a resource hogging solution. Although a keyboard would give me the iPhone-keyboard-bubble-like behavior, i dont think that we can place a keyboard in a static location within a Layout, using it like a View.
So I am wondering what is the best way to go about implementing this. Is my "42 buttons is too many" assumption correct? Is my keyboard assumption correct? Do I have to use a SurfaceView (or something) and draw everything myself? Is there some other grid-like control that can make this simpler?
When I use customized components in XML, could I use a short name of component instead of a fully qualified class name? I wonder if some configuration file exists to do that work.
For example, my customized components is ex.object.RoundRect,
I should use it in xml file like this: <ex.object.RoundRect android:id="@+id/mainRoundRect01" ... />
But
I want to use it like this: <RoundRect android:id="@+id/mainRoundRect01" ... />
Is it possible? Is there a configuration file that can map the fully qualified class name to a short name?

I've looked around and found out it was possible to achieve it with usage off the SOAP protocol. But are there some better ways top implement push? The main concern in this project is the phones battery life, all off it has to happpen over WiFi, pushed content has to be viewable on the device immediately.

View 1 Replies View RelatedAre there any good apps out there for Customized SMS/Email alerts? I am coming from BB Storm 2 where i could have every email, sms, mms, whatever from any contact display a different LED light/pattern and make a different noise depending on who it is coming from. Here on my Droid X i have one alert noise, for EVERYTHING. And no LED tweaking.
I DL'd Blink...which was useless, didn't display 3/4 of the colors it was supposed to do. Uninstalled. I had heard HandcentSMS lets you customize stuff...kinda. I could finally make my SMS make a differnt noise then any other alert. But still can't customize it per person/sender. I could tweak the LED thankfully. But this only affects SMS. Not email. And it too didn't display all the colors it had listed
Ringdroid lets me make every caller have a differnt ringtone (cool), and i can save alerts, but not custom per person. Are there any apps out there that let me customize alerts for email/mms/sms and so forth. So i can have it blink the LED a differnt color from certain people and make a noise when said email, mms, sms is from certain people? Or am i just SOL and need to deal with the fact that i can't do that on a Droid?
In so many ways this phone is lightyears ahead of my Storm 2...but in so many other ways it is far more basic and simplistic in many things and doesn't allow the customization.
I am playing with the AlterDialog with a customized ListView in it.
After the ListView is added into the AlterDialog, there is a centered gradient separator line below the title of the alter dialog, it is just above the ListView.
Is there any way to get rid of it or change its color ? I do not want to show it.
IN our current project, I need to make a UI describled as follows.
Basically it is a text input, it will display a string returned from server , such as "I like banana". The word "banana" will be in red color. When user clicks "banana", it will have a dropdown list shows "apple, orange, pear". User would be able to select one of them, like apple. So the text in that UI would be "I like apple".
How could I build such a UI component in Android.
