View 2 Replies View RelatedAndroid : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory
Jul 21, 2010I 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();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?
Android :: Create Mutable Bitmap From Camera - Draw Another Bitmap On Top - And Save It
Apr 2, 2009I 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.

Jul 14, 2010I am dealing with http post method on Android. I have successfully send simple string pairs using HttpClient and HttpPost class with the NameValuePair as entity. However now I want to send a simple array of bytes[]. Unfortunately the only entities I have found for the HttpPost class are the NameValuePair and FileEntity. However my byte[] is not from a file. Wirting it to a file and then sending by the FileEntity seems to be pointless and stupid. How can I send this array using default HttpClient and HttpPost class?

Cannot Cast From View To ListView

Code:

Mar 18, 2010I 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?
