I am trying to figure out how to do conversion of Picture object generated by web View to Bitmap for later JPEG encoding and saving to local f/s. I tried to create a bitmap from pre created Picture object by BitmapFactory.decode Stream and failed. Seems like Picture object is unrecognized format by Bitmap factory. Just wondering is there any method to do the conversion?

This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3
When I try to construct a java URI object from this object, I get an IllegalArgumentException with the exception description Expected file scheme in URI: content://media/external/images/media/3 whereas the android URI shows the scheme as content
Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.

I want to convert this into a File object, and only a File object - I need to pass it to another constructor that requires a File. How can I convert a URI like this to a File object? If I try File newFile = new File(myURI);I get an error in Eclipse suggesting that I should convert the URI to a String. Supplying URI.getPath() in the constructor doesn't help either.
This relates to the 'How can I convert android.net.uri object to java.net.uri object?' question, which unfortunately seems to have no good answer, but I want a File object out, not a java uri. I don't mind if I have to write it to a bytestream and back again - whatever is the best way.Apologies if I'm cross-posting my own question, but I thought I might need to make things a bit clearer.
I am developing an Android application and require some basic datetime manipulation. I have a Date object (from Java.util.Date) holding a specific date. I need to add a specific time to it. The time I have is a string in this format: "9:00 PM EST"..How would I "add" this time to the previous date? If the Date object currently has: "4/24/10 00:00:00"
How would I change it to instead be: "4/24/10 09:00:00 EST"..I would prefer to do this without the use of an external library, if possible.

I am currently sending and receiving SIP messages across a network. When I want to add SDP data to a SIP message I use the SessionDescription object in jrtp. This object is then added to the SIP message. But when I get a SIP message from the server its SDP is in a byte[] array. So I'm wondering is there anyway to convert the byte[] back into a SessionDescription object so I can use the SessionDescription object's methods to parse the data?

Is there any way to convert a Bitmap to grayscale? I know how to draw a grayscale bitmap (using canvas operations: http://www.mail-archive.com/android-developers@googlegroups.com/msg38890.html) but I really need The actual bitmap in gray colors (or at least something that could be converted to a bitmap later on).
Do I have to implement it by hand (pixel by pixel operations)?

I'm trying to convert my LinearLayout to a bitmap so that I can save the current layout content as an image in SD card. First, I create bitmap and canvas and attach the layout to the canvas.
Followed steps from http://www.brighthub.com/mobile/google-android/articles/30676.aspx#comments.
Code to add child view into layout before creating bitmap:
CODE:............
When I press the save button, it should save the current layout as an image to SD card.
Here are my steps:

It can create folder in SD card but no file created under this folder. It always gives me FileNotFoundException. I'm not sure it is the file creating problem or the screenBitmap problem.

View 2 Replies View RelatedI will try to explain what exactly I need to do.
I have 3 separate screens say A,B,C. There is another screen called say HomeScreen where all the 3 screens bitmap should be displayed in Gallery view and the user can select in which view does he wants to go.
I have been able to get the Bitmaps of all the 3 screens and display it in Gallery view by placing all the code in HomeScreen Activity only. Now, this has complicated the code a lot and I will like to simplify it.
So, can I call another Activity from HomeScreen and do not display it and just get the Bitmap of that screen. For example, say I just call HomeScreen and it calls Activity A,B,C and none of the Activities from A,B,C are displayed. It just gives the Bitmap of that screen by getDrawingCache(). And then we can display those bitmaps in Gallery view in HomeScreen.
I hope I have explained the problem very clearly.
Please let me know if this is actually possible.

View 2 Replies View RelatedI 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.
Uri data = getIntent().getData();

I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.
