I am trying to see if user applications can READ the framebuffer e.g. / dev/graphics/fb0. I find that there is a permissions flag "android.permission.READ_FRAME_BUFFER", but there is no API, which can be used to grab the frame buffer.Is there a plan to provide an API for reading the frame buffer in future android releases?

View 3 Replies View RelatedI'm porting android to an overo gumstix. thus it seems the the omapfb driver has some problems on that platform. it doesn't matter at all, because i want to use udlfb (a driver for usb displays) anyway.
till today, i wasn't able to figure out how i can define udlfb as default framebuffer.
tried make menuconfig and select udlfb there, but no changes when booting the fresh compiled kernel. omapfb still wants to come up.
so my final question: how do i define
the default framebuffer driver for an
android kernel?
I'm using GT N8000 with android 4.1.2 and chroot Ubuntu Raring for my daily work.. I manage to use framebuffer as display WITHOUT turning off android UI using Linux Deploy, all went great but one thing missing is since android and ubuntu shares the same display, input problems pops in, I currently disable s-pen cursor on android so it will work best on ubuntu, as well as bluetooth keyboard.
one thing left out is my Bluetooth mouse, its bugging to have dual mouse pointer on screen whenever I boot ubuntu and each didnt match others in calibration.
if only I can disable android mouse cursor just the way I can disable s-pen cursor in android, this will make a perfect machine.. now I'm stuck using only s-pen as pointing device in ubuntu to avoid erratic mouse behaviour. I understand android have idc as input config, and I've located my dev/input for each devices, I'm looking for a way to disable mouse cursor in android to use it solely on linux.
I am reading the following URL to test a RSS parser. http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/uk/rss.xm

If i have a apk file and want to know the package name and class hierarchy, how do i do it?
Suppose I have some sample APK file named "SampApp.apk" which contains classes inside "com.android.sampApp".
Is there any tool in Android SDK which shows the package name when APK file is passed as a parameter.
As the Class files are compressed to dex file I am not able to check the actual package name.
all in my application I want to read data from web page. if data at web page is upto 800kb then I am able to read it succesfully, but if data is larger then I get OutofMemoryException.I think it is because I am using condition as while ((inputLine = in.readLine()) != null) and in phone there is not much memory to read such a long string. I think I must have to read some part of string then write that part into some file in phone and read another part of string and write into phone but I don't know how to do that? Please help me solve this issue.

View 7 Replies View RelatedI'm running into a strange problem while reading from an InputStream on the Android platform. I'm not sure if this is an Android specific issue, or something I'm doing wrong in general.
The only thing that is Android specific is this call:
CODE:........
This returns an InputStream for a file from the Android assets. Anyways, here's where I run into the issue:
CODE:........
When the read() executes it throws an IOException. The weird thing is that if I do two sequential single byte reads (or any number of single byte reads), there is no exception. Ie, this works:
CODE:........
Any idea why two sequential single byte reads work but one call to read both at once throws an exception? The InputStream seems fine... is.available() returns over a million bytes (as it should).
Stack trace shows these lines just before the InputStream.read():
CODE:........
Changing the buffer size to a single byte still throws the error. It looks like the exception is only raised when reading into a byte array.
I like to know some application to read out Ebooks and docs I have in SD card. I am very new to android.
View 1 Replies View RelatedI want to use Kindle for my Feedbooks but have run into a problem. Before I actually bought anything from Amazon, I was able to use the Kindle app with my Feedbooks as the folder "kindle" was on my sd card and that's where I stored my Feedbooks. (I had to do a workaround and download the books to my pc and then transfer them to the kindle folder on the sd card because I couldn't download the files directly to my phone -- but it worked).
When I bought my first book from Amazon, however, it caused the Kindle app to force close every time I tried to open it. I called Amazon and they told me to delete the "kindle" folder on the sd card but they didn't tell me how to be able to use the Kindle app to read my feedbooks.
To be able to do some accurate calculations that I want for my app, I need to be able to get an accelerometer reading every 100ms. I haven't found a way to do this on android, it seems like the only way to get accelerometer readings is to put a listener that can listen at different intervals. Basically, is there a way to get a reading at exact intervals?
