So, largely for debugging purposes, I want to be able to write an image at arbitrary points in my code, and look at it later. I figured this would be easiest if I just wrote a my bitmap to a file and read it back later, but I cannot seem to figure out where to find the file after I write it, or how to open an image that is not in res/drawable with a corresponding handle in R.

I would like to know how to read in an image file which has multiple frames in it. Something like an animated gif file. I would like to perform frame by frame animation with a file of this type. I don't want to have each frame as drawables in the resource directory. Can anyone throw some light on how to perform the above mentioned tasks.
P.S - I have already checked the example in the API demos where an animated gif is read as an object of type Movie. I don't want to read it in as a movie file.

My Evo is rooted, but I have lost my recovery image. Attempts to re flash recovery via ROM Manager and ADB both failed. I now have a task bar message saying the card is mounted read only. I put it in an adapter, plugged into my PC and ran Check Disk, which appeared to restore R/W status. I then put it back in the phone, rebooted and tried to flash a new image with ROM Manager, I have the read only issue again. I still have root, root apps still receive SU permissions, but I have no nand access and cannot re flash CWM or Amon.
View 8 Replies View RelatedI developed a cramfs rom for the np7 after user dochoppy found root for the nextbook premium 7 tablet, but he then converted to ext3 which because its packed with features will be more popular. So I am trying to edit his ext3 rom in Ubuntu 11.10 and here is what I do:
1. Copy and paste system.img to desktop
2. Create a folder called system on desktop
3. In command prompt:
cd ~/Desktop
Sudo mount -t ext3 -o loop system.img system
(Asks for pw)
4. Doc said something about only being able to edit as root, so after some Googling I find out how to create a program that grants root.
5. (Open "run as" program) then I type "nautilus /home"
(Asks for pw)
6. Navigate to mounted system and I have read/write privileges (but only in this window)
7. View the system mount properties, and it says I have 14.2 mb free space on device
8. Delete files throughout the system folder to make room (but when I refresh properties, free space increase doesn't show)
9. Try to add my own files after deleting some others, ans rather than using the increased space, it just fills the fourteen megs before telling me "device is out of memory "
why is the system not physically making the proper system increase and decreases.
I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.

At the moment I am using the default htc email widget, however when ever I read an email from my gmail account it doesnt update the read status so it still shows as unread.
I would like one that would update the read status and possible the support for unified inbox so I can see new mail from hotmail account and gmail.

I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images.

Just wondering if its possible to use the built in image viewer to display an image sourced from a database. I'm hoping I can pass the byte[] as an extra to the ACTION_VIEW intent, but can't find any docs on it so far. Alternatively I'll have to roll my own viewer or first write the image out to a file and pass that to the intent.

Is there a way to have an image overlaid over another image. For example, I have an instance where I have an imageview and I would like another imageview to take up the same space and appear over the first image. I don't know if there is a way of doing this. I tried putting the second imageview within the first imageview, but that's apparently not allowed in the layout xml files. So is there perhaps a way of doing it with a different layout, such as absolute or frame?
