Android :: Get Content Uri From File Path?
Jun 9, 2010
I know the absolute path of an image (say for eg, /sdcard/cats.jpg). Is there any way to the content uri for this file? Actually in my code I download an image and save it at a particular location. In order to set the image in an ImageView currently I open the file using the path, get the bytes and create a bitmap and then set the bitmap in the ImageView. This is a very slow process, instead if I could get the content uri then I could very easily use the method ImageView.setImageUri(uri)

I am launching an image picker (from the gallery) and my code crashes every single time. I tried to get some help in another post, but people quit responding to the post. Please help. When I do a debug, it tells me this (there are TONS of errors, but these looked the most important - also, I changed the "com.app.name/com.app.name.activity" for privacy reasons):
04-01 14:09:30.254: WARN/dalvikvm(719): threadid=3: thread exiting with uncaught exception (group=0x4000fe68) 04-01 14:09:30.254: ERROR/AndroidRuntime(719): Uncaught handler: thread main exiting due to uncaught exception 04-01 14:09:30.274: ERROR/AndroidRuntime(719): java.lang.RuntimeException: Failure delivering result ResultInfo {who=null, request=1, result=-1, data=Intent { data=content://media/ external/images/media/7 }} to activity {com.app.name/ com.app.name.activity}: android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1 04-01 14:09:30.274: ERROR/AndroidRuntime(719): Caused by: android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1
Here is the code that invokes the activity, follwed by the code that is invoked after the activity has finished:
public void takePic() { Intent photoPickerIntent = new Intent(Intent.ACTION_PICK); photoPickerIntent.setType("image/*"); startActivityForResult(photoPickerIntent, 1);
}

In the app I am making, I would like to take a Base64 image that is received from a server, and save it to a file for displaying later. My question is where should I store this file? It needs to be dynamic, and may be empty when the program launches. I am unsure how exactly the file system on Android works, such as how file paths look.
Ideally I would like to be able to write the data to the image file using a FileOutputStream, and then display that image somehow.

I realise one has to use an intent filter to associate a file format with an application, but once this is done how does the app 'receive' the path to the file that was chosen? Is there a special method it calls on the Activity?

Is there a way to read the points created when drawing a path? It seems silly to me that a path cannot be readable.Or is it just better to manually write the current finger position to an array?

I needed a tun.ko module for my kernel, so I tried compiling my own kernel.
The kernel did build OK, and also boots OK, the only problem is that I cannot load any modules.
It seemes, that the module tools (insmod, modprobe etc) looks for the modules in /lib/modules, and I have them in /system/lib/modules, so my wifi does not work, as I cannot load the module.
Where I can specify the kernel module load path in the .config file?
Example:
# cd /system/lib/modules
# ls -l
-rw-r--r-- root root 315403 2008-08-01 14:00 bcm4329.ko
-rw-r--r-- root root 211573 2008-08-01 14:00 tun.ko
# modprobe bcm4329.ko
[Code] .....

I have used the 'wireless file transfer' program on my PC to send an audio file to my Xperia X10. It sent fine, but I can't find the file on my phone. In case it hadn't sent properly I sent it again but was told the filename already exists at the destination. It's not in mediascape, it must be in a folder somewhere, but where?
