Android :: Create ADT Virtual Machine Of Specific Size That Still Has Hardware Control Buttons

Aug 9, 2010

I'm trying to develop a very specific app for my Dell Streak. I want the entire app to run landscape. The Streak has a tilt function that switches the whole OS to a landscape 800x480.

So I want to make an ADT to test in that uses an 800x480 display, but whenever I set the size I get no buttons. The Streak has a Home, Menu and Back button aswell as volume/mute and power, and I need to use some of them for my application.

I'm not worried about the tilting messing up my application. Not yet, anyway. Just need the test environment the right size and with buttons.

Android :: How To Create A Custom Control / Buttons Inline?

Dec 22, 2009

I have a need to create a control similar to UITabBar in iPhone, which is to be present on every activity of my application. UITabBar essentially is a battery of buttons exhibiting a TAB like behavior: every button maps to an activity. I have two solutions for this: 1. In the layout XML for every activity, I insert a <LinearLayout><Button/><Button/><Button/></LinearLayout> element. And then have a common listener class that will handle the button clicks. So, every activity will have an instance of this listener. 2. To create a custom Widget extending LinearLayout class, put all the buttons as its static members and let it handle the button clicks. Include this custom control in every screen. I am not sure which approach to follow.

Android :: Run On Virtual Machine For Development

Jul 15, 2010

Currently I am using Android emulator for development, but it is very slow. I am looking for some android port that can run on real CPU.

For example I installed this product on VMware, and it seems to work much faster, but I have no idea how to setup network connection here.

The question is if some one is using alternative android setup for development, instead of emulator? If so, a link to configure instructions would be great.

Android :: C Development - Virtual Machine - Allowed

Apr 4, 2009

I'm the lead developer of TotalCross, a virtual machine that's just like the one used in Android, and targetted for small devices. Currently, using TotalCross, you write programs completely cross- platform among Palm OS 5, BlackBerry, iPhone, Windows 32, Windows CE (2,3,4,5,6) and Java-enabled platforms.

We plan to port TotalCross to Android, but i'm concerned about the legal way. I'm aware that there may be hack C APIs for Android, but will these APIs allow the users to sell their applications in a legal fashion?

Btw, what is legal and what's not legal in Android? I could easily port our VM to Android if there were a standard C api on it. However, all i see is Java APIs. I could also port TotalCross to run over the Java API, but i'm concerned about speed. I believe our VM is faster than the one in Android (actually, it is a couple times faster than the BlackBerry VM).

Android : How Would You Improve Dalvik In Virtual Machine

Jun 21, 2009

I am currently writing a paper on the Android platform. After some research, it's clear that Dalvik has room for improvement. I was wondering, what do you think would be the best use of a developer's time with this goal?

JIT compilation seems like the big one, but then i've also heard this would be of limited use on such a low resource machine. Does anyone have a resource or data that backs this up?

Are there any other options that should be considered? Aside from developing a robust native development kit to bypass the VM. For those who are interested, there is a lecture that has been recorded and put online regarding the Dalvik VM.

Any thoughts welcome, as this question appears subjective i'll clarify that the answer I'll accept must have some justification for proposed changes. Any data to back it up, such as the improvement in the Sun JVM when it was introduced, would be a massive plus.

Android :: Doing Coding In Linux Through A Virtual Machine On Windows VS Partitioning

Mar 29, 2010

I already have experience with setting up virtual machines, running them and other minor tasks. Im a gamer, so I wont get rid of windows (for now at least...) but I do want to be a great programmer and to be involved with the Open-Source community Id like to know if its a good idea to do my programming in linux through a virtual machine, vs giving it a partitioned section of the HDD. Id like to know about performance pros and cons and functionality.The type of programming I intend to dive into : Android Dev, Web Dev, Desktop Dev...More Android and Web right now though. I do web designing as well, so dreamweaver is added as an "essential". But im sure I can do dreamweaver files and upload them to the server after programming in Linux...Right? And any info on IDE's in Linux for the above mentioned are appreciated, but i would prefer going the coding route and understanding the essence of whats happening "under the covers".

Android :: Create A Custom Answering Machine In Droid?

May 5, 2009

I'd like to create an app that allow you to filter incoming call to various answering message with :

"this number is not available" for black listed phone numbers
A formal message for strangers
A informative message about what your doing for friends

I don't know I you can get automatically a call, play a recorded message then wait for the answer and record it. Or maybe there is just a way to interact with the actual answering system so I just have to plug in.

Android :: Add Another Virtual Keyboard Do Simulate Control Keys?

Jan 13, 2010

I am working with an hardware that have just five buttons. But I have just one button available to the following functions: home, back, search, soft-back(menu). The hardware is for automotive use, so that is because he doesn't have the common buttons of a cell phone. So I am thinking about create a second virtual keyboard that is called by this available button, to show these buttons that are missing on hardware. I want to know if it is possible to do. If it is, what type of code should I follow to create this extra virtual keyboard? I think a good start is to look at the code of the current virtual keyboard.

Android :: Virtual/soft Buttons For Home - Menu - Back - Search - Always On Top

Jun 9, 2010

How can I make an app or maybe service that looks like (Nexus One touch buttons) for the navigation keys (Home, menu,Back, Search)

The buttons should always be visibly and always stay on top and send the command to the app thats running.

Someone have ideas and sample codes how to do that?

*I see an app with name (Smart Taskmanager) wich always detect when you touch the right side of the screen and then detect when you slide the finger to left.

So I think its possible, with this function I think its possible to implementate the code to simulate the (Home, Meny, Back, Search) buttons.

*I also see and test an app wich show a "cracked display" always ontop so that tecnic maybe shold be useful to always show the buttons/bitmanp on top.

Thoose function, to show the button and catch the "touch event" and send the event to the active program, thats what i dont can figure out how to do.

Android :: How To Tie Pending Intents To Specific Buttons On Widgets?

Sep 18, 2010

I have a Widget I am working on, that allows the user to have more then one instance of the widget on his screen. Each Widget ID maintains its own configuration file. However, for some odd reason my code that is responsible for setting up the buttons individually for each widget id is not working, only the first widget id is linked to each individual widget. Below is the code that is responsible.

private void TieClicks(Context context){
RemoteViews rViews;
PendingIntent editPendingIntent= null;
// Intent updateintent = new Intent(context,SyncNoteWidget.class);
// updateintent.setAction(SyncNote_Action_Widget_Update);
// PendingIntent pendingupdateintent = PendingIntent.getBroadcast(context, 0, updateintent, 0);
// rViews.setOnClickPendingIntent( , pendingupdateintent);
// AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
int[] ids = appWidgetManager.getAppWidgetIds(new ComponentName(context, SyncNoteWidget.class));
for (int i =0;i< ids.length;i=i+1){
int wId = ids[i];
rViews = new RemoteViews(context.getPackageName(),R.layout.widget);
editPendingIntent = makeControlPendingIntentActivity(context, wId);
Log.v("syncnote", "tieing " + String.valueOf(wId));
rViews.setOnClickPendingIntent(, editPendingIntent);
appWidgetManager.updateAppWidget(wId, rViews);
editPendingIntent= null;
} }
private PendingIntent makeControlPendingIntentActivity(Context context,int appWidgetId) {
Intent active = new Intent(context, EditNote.class);
active.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
active.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
return(PendingIntent.getActivity(context, 0, active, 0 ));

Android :: Call Specific Function On FocusChange Of All Buttons In Droid?

Sep 24, 2010

It's possible to specify a particular function to be called when button is clicked by setting its onClick attribute in xml:
I want to do something similar for FocusChange of buttons, is this possible?

Specifically, I wish to increase my button's size when it has focus and make it normal sized when not focussed. To apply this to all my buttons, I hoped to call a specific function which does this and then specify this function name in my style.xml. But there is no onFocusChange attribute in android.

It works when I add overriden onSetFocusChangeListener for each of my buttons separately in the code. But is there any other solution?

Android : Way To Control An App's Cache Size?

Aug 10, 2010

My app has a WebView which displays Google maps. I'm trying to limit the cache size to a reasonable one - like 2MB. After checking with settings->applications->manage applications I found out that regular page load gets the cache to 900kb. And dispite my efforts, I can't limit the cache size or monitor when the cache limit is being reached. If I'm playing with the map on the webview, the app can even reach 10MB and no "ache max size reached" message is received.

Android :: Programmatically Control Size Of Child View In AbsoluteLayout

Feb 18, 2009

The documentation at says:
onLayout(boolean changed, int l, int t, int r, int b) //Called from layout when this view should assign a size and position to each of its children. So I overrode it like this:

protected void onLayout(boolean changed, int l, int t, int r, int b) {
Log.d("test", "In MainLayout.onLayout");
int childCount = getChildCount();
for (int childIndex = 0; childIndex < childCount; childIndex++) {
getChildAt(childIndex).setLayoutParams(new LayoutParams(100, 100, 100, 100));
super.onLayout(changed, l, t, r, b);

I am declaring the child elements (buttons) in the XML for the layout. This correctly sets the position of the buttons but not the size. The size is being taken from what is defined in the XML (it's a required attribute).

Android : How To Change Size / Color Of Phone Buttons?

Sep 4, 2009

I would like to know the way to make a user interface for Android for people that have low vision. The idea is to make a UI with the following features: 1- Uses very very big buttons. 2 -Uses very big font size. 3- Te colors to use are basically black and white (for more contrast). 4- The icons in this UI are not relevant. 5- We must sacrifice the number of chars that we can show in the screen to get bigger labels and buttons. 6- A simple zoom system for the images should be a great idea. 7- We can use the camera of the phone to get a magnifying glass. I'm member of a blind people association in Spain and we think that this should be a great idea for begining a new low-vision-user- interface that is not aviable in the market for the new mobile phones. This will help many people that uses movile phones but have many difficulties to work with them.

Android :: Text Boxes / Labels Buttons Shrink In Size

Mar 2, 2010

I designed the user interface of my app on the emulator and then I installed it on the Nexus one. For some reason the text boxes, labels buttons etc. have shrink in size. It looks as if the view has been zoomed out on the phone. If I arrange it correctly on the phone the objects don't fit on the emulator. Has anyone faced this? Is there some setting to have consistency between the look of the emulator and Nexus One.
