View 2 Replies View RelatedCan you please tell me if we can still compile froyo source on Mac OS X 10.5? Is it true that we need a 64 bit environment and Java 6 in order to compile froyo source?
I don't think 10.5 is 64 bits and has Java6.
As far as I'm concerned, Android uses another Java Runtime Environment called Davilk, which is NOT compatible with common Java applications.

Can 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));
I want to refer to a static Java variable in my styles.xml, is that possible? Here's a pseudo-xml example:

I'm writing an android app that requires binding a JSON object into a domain entity with the keys from the JSON as instance variables. Since there are several domain entities, each with different instance variables that the JSON needs to bind to in the app, i'd like to write a method such as ths following: Loop through all the instance variables from the domain if a key exists in the JSON with the name of the instance variable, take the value for this key from the JSON and set the Domain's instance variable with this key name equal to this value. The reason i'm interested in the doing the binding from the class to the JSON is because if the JSON changes for some reason, I don't want it to break the app when the instance variable doesn't exist in the app's domain for a specific JSON key.

View 1 Replies View RelatedOk so I know many are having battery issues. You, like me, probably have more battery life than you think. 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 RelatedIs copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

View 3 Replies View RelatedIs 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 2 Replies View RelatedSo i've been trying to flash modules from within the phone without having to boot into the recovery, and i found that i can just extract the update-binary and execute it through shell and it will do the trick!!
However, know im trying to do that through my app, I successfully got root access using Chainfire's libsuperuser, however, whenever i send the commands to run update-binary i get "segmentation fault(core dumped)" Error.
the command i using in both shell and from within the app is "./update-binary 3 stdout ./modules.zip".
This might be irrelevent but when ever i add a number before stdout (e.g 7stdout) i get segmentation fault during shell as well, other than that, i can't find the problem.
This is a logcat of the process through strace, if we have a linux debugger here
Code:
08-24 17:06:43.568 8703-9188/com.thunder.kernel.lighter D/libsuperuser: [libsuperuser][SU*] execve("./update-binary", ["./update-binary", "3", "recovery", "./KernelLighter.zip"], [/* 24 vars */]) = 0

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?
