View 3 Replies View RelatedDoes anyone know what approach one can take to automatically generate Java source code, from for example an xml or json file, in eclipse? One great example of what I am thinking of doing is what Google Android sdk does: they have an R class generated automatically from the resources. Every time a resource file is saved in Eclipse R class is automatically regenerated.
UPDATE: Example:
In the text (xml or json file) I have the following:
<tags>
<tag id="ALPHA">
<description>The first alpha tag.</description>
<value>231232</value> </tag> <tag id="BETA">
<description>This is the beta tag.</description>
<value>231232</value> </tag>
Then in my generated java class, say R I would have something like:
R.tags.ids.ALPHA //refers to an enum value for example
R.tags.values.ALPHA //refers to final int with avlue 231232
R.tags.descriptions.ALPHA //refers to the String with description

Are there any tools to inject code generating new dalvik bytecode? I am studying some libraries, aspecjt or guise for android. Is it better to work with a script language?

I am trying to implement a functionality when i press the VOLUME DOWN and POWER BUTTON simultaneously; i must be able to run a method code inside my Activity.
public boolean onKeyUp(int keyCode, KeyEvent event)
{
}
From my initial search; it seems that only one such key press event is acknowledged at a time in Android usng the onKeyUp method. Is it true?
In my Android phone, on simultaneously pressing POWER BUTTON as well as MENU BUTTON i am able to capture a screen shot.
Does this feature not acknowledge simultaneous key presses?
Are there api to support go to back Programmatically i.e same effect as the back button of the phone.
View 5 Replies View RelatedI am trying to catch when the user has pressed the Home button. I thought I could use
protected void onResume()
{
registerReceiver(homeReceiver, new IntentFilter(Intent.CATEGORY_HOME));
}
...
private BroadcastReceiver homeReceiver = new BroadcastReceiver()
{
public void onReceive(Context context, Intent intent)
{
// logic here
}
};
but that doesn't seem to work. I understand that onPause will be called, but my particular app has some logic that I need to handle separately. Short story is based on some info coming in, the app will display new Activities to the user. To prevent Back button issues, as each Activity hits it's onStop it calls finish on itself. However if the user presses the Home button I do not want the Activity to call finish so that when the user presses the app icon on the home screen or via the Recently run apps list, the last Activity is brought back
I realize the Camera button on the Droid X is not a standard feature across all phones, so, I'm curious how to attach a callback to it. I have a camera application that I wrote and I want the user to be able to snap the picture by pressing that button, but currently it doesn't work that way, so, I'm wondering how to attach my callback to it.
View 1 Replies View RelatedMy application uses GPS updates while it is running and I would like that to stop when the user back out of the app as I assume it will continue wasting a lot of battery power. I've tried intercepting the back button press but it doesn't seem to work. I'm not sure if this is because it's not executing the code or I'm using the wrong command.

I'm creating an Android application which uses user captured images as part of a larger process. So far my XML layout has a SurfaceView and Button inside a RelativeLayout. I've managed to get the camera preview to show on the SurfaceView but I'm stuck on how to take a picture and save it when a user presses the button.

View 2 Replies View RelatedHow can I capture a long press of the device menu button in my application?I thought of an intent filter, but there's only an action called android.intent.action.SEARCH_LONG_PRESS, but nothing for the MENU button.I found that long press of the menu button actually does different things on different devices,i.e. on Nexus One it will show the soft keyboard, while on Samsung Galaxy S it will pop up the search widget.
View 5 Replies View RelatedThe docs say "The onStart() and onStop() methods can be called multiple times, as the activity alternates between being visible and hidden to the user"When I press the back button an it will go back to the previous activity which totally covers the old one.What is going on here?
View 1 Replies View RelatedI have an Activity with an EditText, a button and a ListView. The purpose is to type a search screen in the EditText, press the button and have the search results populate this list. This is all working perfectly, but the virtual keyboard is behaving strange. If I click the EditText, I get the virtual keyboard. If I click the "Done" button on the virtual keyboard, it goes away. However, if I click my search button before clicking "Done" on the virtual keyboard, the virtual keyboard stays and I can't get rid of it. Clicking the "Done" button does not close the keyboard. It changes the "Done" button from "Done" to an arrow and remains visible.

View 2 Replies View RelatedIt is difficult to test a game with the mouse pointer on android buttons. I would like to control those buttons with the hardware keyboard. Actually I don't want to control the buttons itself but I want to control the behavior the buttons would also do. For example I have 4 buttons in the android application with "arrow up, down, left, right". I'd like to use the arrow buttons of my hardware keyboard to control the same. How can I do that? Actually the question is, where can I set the Listener? I tried something in my activity.
View 1 Replies View RelatedBrand new to droid programming, but would love to learn as much as possible, so I finally got my emulator working correctly, I even got a hello world button to work. I'm attempting to make this button display a random number, I've googled this and came up with this code:
Random generator = new Random();
int n = generator.nextInt(n);
I fixed the Random function by including some Random java utility. I'm assuming this code above goes in the .java file of the project, so my button code looks as follows (tested and works):
PopUpText.makeText(v.getContext(), "Hello World",
PopUpText.LENGTH_LONG).show();
I figured I could replace "Hello World" with n to display the number in the box, however the following error is stopping the compile:
The local variable n may not have been initialized

View 1 Replies View RelatedI have the motorola droid. I got the handcent app because I really like all the customization options within it. However, lately I have been having this annoying problem. Sometimes when I have just sent a message, when I press the home button to return to the homescreen, it goes home but all my apps have vanished. I can go through my menu and replace them all to where they were, or I can reboot the phone and that usually corrects it. It is still annoying and is really putting me off the app. Has anyone else had this problem? Do you know if there is a specific cause or how I can correct it?
View 2 Replies View RelatedI preordered my Incredible online on the evening of 4/20.Up to this point I'm still getting the same order status message as everyone else here. All seems normal and on par with everyone else here.However, I've heard people saying that they show a $1.00 charge on their credit card account or whatever showing that they made the purchase and then that charge will turn full once the phone ships or however Verizon does it. My online Verizon account that this card is attached to isn't showing any trace of a charge from Verizon. Should I be concerned?I purchased mine with my Wells Fargo Visa check debit/credit card. The Verizon site asked for that Visa Verify (or whatever it's called) password to verify my card. I honestly didn't remember that password, but I figured it would be the password that I use for almost everything. I entered that password and the page had a processing icon or whatever and I proceeded to complete my order. I know I've used that Visa Verify before, but I just didn't remember the password.
Based on that info, should my card have been verified on the spot if it allowed me to pass the Visa Verify and complete my order? Or does Verizon do that verification later? Should I be seeing a charge from Verizon in my online Wells Fargo account yet?I just want to make sure something as small as not entering my Visa Verify password is going to make me miss out on this phone on release day.
As the days have gone by, i have started to notice that the power button on my evo might "recessed" more, because it has gotten to the point that the only way i know i press it is because the screen turns on. Reason for an exchange?
