How can we display a buffer on screen?
Currently I create a bitmap using Bitmap's CreateBitmap() and render it on screen using canvas' drawBitmap().
Is there any other way of doing this in Java layer?

Currently I want to develop one Activity to allow the user to see the screens/activites of all running tasks , then the user can select one of them to switch it to foreground. As I known, HTC Sence seems already to have this implementation for Home screen, to display the thumbnail of all Home panels in one screen. Does anybody know how to access screen stack in Android?

Is this possible using the standard android apis?
Is it possible, from within my android java app, to capture an image of what is on the screen, even if it was written using native (ndk)? I do not wish to take screen shots of other apps, just my own. I can already capture and image of a canvas that I am aware of, but is there a view or canvas or something like it that always represents what is on the screen, so that a) I don't have to capture the separate views images and recompile them, and b) I can see what my native (jni) code is doing with the graphics too?
View 1 Replies View RelatedI'm working on an Android app in which I would like to use multi-touch. However, I do not want to completely leave out those still running a 1.x OS phone. How do you program the app so that you can use the 2.x multi-touch APIs (or any other higher level API for that matter) and still allow it to gracefully degrade on 1.x systems. If you create a project in Eclipse for 1.x can you even still access the 2.x APIs?
Basically I want it to show up in the marketplace and work on all 1.6 and higher phones and just allow access to the higher level functionality if available.
Also, if anyone can point me to any data on the number of 1.x devices vs. 2.x devices in use.
I have recently started working on an app which has both Java and native components. I am trying to generate trace information for both components using Debug.startMethodTracing("myapp") and Debug.startNativeTracing() alternately.
However, both are behaving unexpectedly.
When I use Debug.startMethodTracing("myapp"), I can see a file /sdcard/myapp.trace being created but it is always empty no matter how long I run my app. When I use Debug.startNativeTracing() and start the emulator with the -trace <tracename> switch, I see a message saying "Trace started", but when I try to run my app, the
emulator crashes.
It seems a little ahead of tomorrows Google event.But I'm already getting many complaints that my app fails completely under Android 2.2.So that scares me a lot!Anyone know when the API might be released? Tomorrow perhaps?

1. MD5 is easy to be changed.
2. First I got the MD5 of my app ,and then submit, but when I add the new keys, if the MD5 is changed, there will have the problems of the martch.
3. what should I do?
I'm building an app where I want to architect the app layer separately from the service layer (not android services). So I'll create a service interface(the apis) and then create a class(es) that implement that service interface. Inside the android application layer, I want to code to just that service interface. I think this is similar to how the google maps apis works. the api interface and stubs are in the framework, then each device actually provides the implementation. I don't need to go that far, but I am wondering how I package this up. One, where would I put these interfaces, so I can code to them in the app layer (like Activities). Second, how do I tell Android where the implementing classes are? I'm guessing this is somewhere in the manifest? For now I think I would probably just build the service implementation with the application source code, if that's easier. Eventually I'd like to break that out and drop it in as a 3rd-party jar.

In my android app, I need to design a Welcome Screen which will be shown to the user only once after the app is installed and opened. The app in question is a database driven app and I would love to include some 3 - 4 screens to help the user create re-usable resources for use within the app and a few tips. They would be Dialog Alerts with the last welcome screen showing the "Do Not Show Again" checkbox. how to show the welcome screen just once.
View 3 Replies View RelatedI have a requirement to turn the screen display on and off from a Android Service. I should have a function SwitchScreenDisplay (ON/OFF), to ON or OFF the display. I searched through the SDK and found a few APIs and settings. One method I found is
boolean err = android.provider.Settings.Secure.putInt(myThis.getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT, 1);
But it gave the following security permission exception
[03-14 21:24:41.575: ERROR/DatabaseUtils(1066): java.lang.SecurityException: Permission denial: writing to secure settings requires android.permission.WRITE_SECURE_SETTINGS] even though I had added the following statement in
AndroidMenifestFile.xml <uses-permission android:name = "android.permission.WRITE_SECURE_SETTINGS"></uses-permission>
So my question is: Was the above method is the right way to SWITCH OFF the screen - How does the Long End Key press, switches/powers off the display? Which API it calls? - How to Switch on? Is it using the PowerManager wakelock?
My project group for our senior project is developing an Android app. We are pretty much done at this point, but we have to present our app on Friday. We have done a practice presentation with a demo on the emulator, but we would like to present it on my phone.
I was wondering what is the best/easiest way to put my Android display on a PC so we can do our presentation on my phone the way it was meant to be shown.
So it would be my phone connected to a laptop, laptop connected to projector, and laptop displaying my phone's display on the projector.
This way we can also use our GPS location and use the app to take pictures which are both important parts of our presentation.

I read some where that earlier googlenav package was there in Android SDK, but it is now removed. May I know the reason for removal of this package, or When can i expect it to come back with fixed version of googlenav in Android? Looking forward to your reply.
Or is it essentially the same SDK/APIs as standard Android development?
