I've got an activity for which I've defined an intent filter statically in AndroidManifest.xml. I'd like to register additional intents dynamically to that same intent filter in the activity's onStart() method. Is this possible? I'm trying to avoid having to implement a separate intent receiver class. ...
Hey there. My app is going to be using an array of 64 ImageButtons (8x8), and they're all already declared in my XML Layout with names like one1, two5, eight8, etc. Rather than declare these each individually in my Java I thought it might be smart to declare them all in some for loops. I have ImageButton musicGrid[][] = new ImageButton ...
I have an ImageView that contains a bitmap. Now the bitmap can change size within a known range. This makes the surrounding views to relocate which I want to prevent. I've tried setting margins and padding for the ImageView but without success. Any ideas? Thanks, Christian ...

I'd like to make my Android app responsive, even when the network connection is not. For certain calls, the data doesn't change that often, so I'd like to be able to retrieve the most recent XML response for a given call. Ideally, I'd like to do this similar to how web caching works, hash the call/params, set rules as to expiry, etc....

When I looked at logcat on my phone (HTC EVO) I see this: I/HTTPStream( 65): 1358 Bytes read, progress 34346/65536...

I'm finding the need to lay out a fairly complex UI manually, by giving the dimensions and position of most all of the sub views. My plan is to code the XML initially for a 480x320 display, get it all working right to demo for the client on a given device, then modify it for production by programmatically adjusting the size and position...
I find the force close Report option very useful as a developer- the stack trace is really useful to see and I've been able to solve many bugs by using it. However, there are places in my app where (quite rightly) I've used a try/catch statement to handle Exceptions. The problem being, that this prevents a force close and so I can't ge...
I'm trying to user the LayoutInfator to create a view. One of the options I'm thinking about is using the default android.R.layout files. However I'm finding it difficult to locate these files/how they look. It would be great if I could get some help in locating the source. I need to find the id's of the individual elements within those ...
