I've got a standard RelativeLayout laying out my Buttons and TextAreas. What I want to do now is be able to draw various sparks, flying cows etc. at arbitrary places on the screen on top of the whole thing. What's the best way to do this? Should I override onDraw() on the containing View and draw after calling super.onDraw()? Or is there some better way of drawing a layer on top?

I want to set the background of a Relative or LinearLayout to a custom drawable. I want the shape to draw two horizontal lines across the bottom, leaving the central part transparent (empty). The following draws the horizontal lines centered vertically, where as i need them to be aligned to the bottom of the shape. (If you add a rectangle as an item you can see the shape expands to the dimenstions of the parent, but the lines are still centrally aligned). Code...

This is because the application layer of the phone is not receiving the hardware layer's data correctly (hold talk button, end call button, and middle button upon starting up your turned-off phone, this boots in test mode which shows you hardware layer battery power, aka the correct battery life estimate). It's causing another problem because some applications can't be run when the phone THINKS it's about to die.

View 2 Replies View RelatedI have a GIS layer, that holds information about some areas. It is basically a rating for a specic area. So each shape defines a specific rating. I would like to be able to add this layer to Google Maps and then in my Google Android phone be able to open a little application that just shows that rating based on your current location as a big number on the screen. I am fairly new to Android development, so I don't know the Google Maps API that well yet. I would be very happy for any pointers in the right direction and even happier if anyone could present an example.

View 6 Replies View RelatedI dont know wether this is the right place to post this, but I had a great idea for a implementation of Contacts within google maps. Maybe it is already possible or someone already is developing this, but here it is: Add a selectable Layer to the Google Maps on the Android system that integrates with the Contacts list and shows them in Google Maps. Only contacts with an adress can be shown in Maps and have to be in a certain format ofcourse. Also, you have entered a contact's adress information, from the Contact's menu with 'Call' and 'Text you should be able to use 'Navigate to', which is a Google Maps route from your current location to this person's house.
View 2 Replies View RelatedI'm starting my first Android Application and I'm trying to figure out the best way to implement an RPC layer to communicate with my Tomcat server. Basically, I've got POJOs on the Android Client and on the Server. I simply would like to seserialize the POJOs on Android, send up an HTTP Post, deserialize on the server, do some work, then serialize a POJO response back down to the client. I've seen a number of posts referencing JSON and XML but nothing really definitive.
Further clouding the matter is the different Android SDKs out there that seem to have different levels of support for each. Obviously, if Android has a native library that works well, I'd like to use that. Additionally, I'd like something that could work with my existing POJOs without a great deal of trouble. What are the best practices for this sort of thing? Can anyone send me to any tutorials that have some solid examples on how to get this implemented and going?
I have a few already written C libraries which i want to embed into the library layer of the android architecture at the same level as the already existing libraries such as libc etc.... i dont want to insert it as .jar packages at the application or framework layer. is that possible.
View 2 Replies View RelatedI am working on a device that uses dns names and IP addresses to make calls. This is not phone device. We are planning to replace the RIL layer bottom end to talk to our own call backend that accepts IP addresses. When I invoke a ACTION_CALL intent with a dns name, I see the Phone app coming up and changing the dns name into a phone number. Is there any option to turn that behavior off? Basically the phone app passes whatever string I passed all the way to RIL layer as is without mangling it.

I want to create a communication layer in android. The layer will communicate with server asynchronously. Multiple activities should be able to call methods of the communication layer. The layer will get messages from the server (it is not important for the scope of this question how) and should be able to tell activities to do some work based on these messages.
How should I implement this? Should I do this using android Service?
The main questions that I need to answer are: How can activities access the layer? How can the layer access activities? How can i make the communication layer live for the lifetime of the application?
Is there any Java ME compatibility layer for Android, which makes porting Java ME (aka. J2ME) applications easier? I mean a third party class library which redirects calls to internal Android API.

I'm a little uncertain though on how to implement the Model layer.I come from a background in PHP web applications with Zend Framework and the like. I'm used to having an ORM component, through which the Model maps to a database. I haven't really seen anything like this yet for Android, although it's possible I've just not looked hard enough.Are there any good tutorials, articles, 3rd party libraries, etc. that specifically address setting up your Model layer for Android apps?
View 3 Replies View RelatedCan a core class such as "AbsListView" access resources, such as xml files, and .png's, in a 3rd party app installed in the normal way (at the app level)?
I realize this is a change in framework code, and that is fine for my purposes. So, for example, if I know that I am going to install an app called "MyApp", could I go into frameworks/base/core/java/android/ widget/AbsListView.java and tell it to use an xml file and .png's that live in that app? Here is the line I would want to modify: setSelector(getResources().getDrawable( com.android.internal.R.drawable.list_selector_background));

To use this "Context", in my service layer class, I extends Activity class, though I do not display this activity on the screen because it is my service layer. I always get NullPointer exception when I open the SQLiteOpenHelper in my service layer class, Is it because my service layer class extends the Activity class but I did not show this activity on mobile screen? (That's there is no intent to my service layer class), if it is so, how to get rid of it if I wanna open a SQLiteOpenHelper in my service layer class which do not need to extends Activity, but need a Context object to pass to SQLiteOpenHelper?

View 3 Replies View RelatedIn my application i want to pass the camera data to native layer. what is the best possible approach for doing the same.
I know it can be done 2 ways.
1.start the camera in application and pass the preview data to native layer. But i feel this may consume lot of resources.
2.Start the camera directly in native layer and use it. So JNI will come less into picture. and not much resource loading also.But dont want to take any risk by using the lower layer code which may change in future.
Is there any other approach ? start the camera and tap the data in native layer. I think this wont be proper approach, Can any one suggest ?

View 7 Replies View RelatedI am sending text to my app through a QR code via calling barcode scanner with an intent from my app.
Let s say I generate 2 QR codes. #1 passes "Frank" #2 passes "Upfront".
This is no problem, but what happens if someone scans the QR code with the barcode scanner on it's own? They will be presented with the text "Frank". Useless.
Can I have it link to the android market if they do not scan from my app? And if they do, it passes the string?
The only other option that I see is to have it present a message: "Go download my app, Frank" and remove the "Go download my app" from the string if it is passed to my application.
I'm writing a game using the drawing method from Chris Pruett's opengl spritemethodtest demo. The Activity running my opengl view works fine on initial load, and about half the time after turning off the phone and turning it back on. However, the other half, it locks up. I'll get a "lock_layer timed out (is the CPU pegged?)" warning that keeps repeating. I tried running the debugger to find the exact line that the error is occurring on, but the strange thing is that this error won't occur if I'm running the debugger on my G1. It only happens under normal operating conditions. Any help would be appreciated, as this bug really has me stumped.
