How do I get a bitmap of a webview? I think I can use the capturePicture but how do I then convert that picture object to a bitmap that I can clip and manipulate?

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 3 Replies View RelatedI am trying to get the webview's content on a bitmap so that i can save it as a image. But I am unable to so. I am getting the BLACK image save instead. All content is missing. Here is my code:
//create a webview WebView w = new WebView(this);
//Loads the url w.loadUrl("http://www.yahoo.com");
//After loading completely, take its picture Picture picture = w.capturePicture();
//Create a new canvas Canvas mCanvas = new Canvas();
//Draw the Picture into the Canvas picture.draw(mCanvas);
//Create a Bitmap Bitmap sreenshot = Bitmap.createBitmap(picture.getWidth(), picture.getHeight(),Config.ARGB_8888);
//copy the content fron Canvas to Bitmap mCanvas.drawBitmap(mBitmapScreenshot, 0, 0, null);
//Save the Bitmap to local filesystem if(sreenshot != null) {
ByteArrayOutputStream mByteArrayOpStream = new ByteArrayOutputStream();
screenshot.compress(Bitmap.CompressFormat.JPEG, 90, mByteArrayOpStream);
try { fos = openFileOutput("yahoo.jpg", MODE_WORLD_WRITEABLE);
fos.write(mByteArrayOpStream.toByteArray()); fos.close();
} catch (FileNotFoundException e) { e.printStackTrace();
} catch (IOException e) { e.printStackTrace(); } }
I create a WebView object in the OnCreate function. Now I need to be able to pass this same object to other functions in the code, such as the onOptionsItemSelected function. I currently have it where I just create a new WebView object in each function where I need it, but this slows down the code since it has to recreate it and such.
View 1 Replies View RelatedI have some images that I loaded from a remote source stored in Bitmap variables and I want to display them. In addition to switching between these images the user should also be able to zoom and pan them. My first idea was to somehow pass them via an intent to the built-in gallery application but this doesn't seem to be possible.
A solution that is suggested in several places is using a WebView since it already supports zooming and panning.
My question is how does my Bitmap data get into the WebView? Do I have to write it to a file first, which I would have to remove again later, or is there an easier way?
Or are there even better ways to accomplish my main goal, which is displaying Bitmap data as zoomable and panable images?
