Android : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory

Jul 21, 2010

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.

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, 2009

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.

If I want to draw something transparent over a bitmap, how would I go about doing it?

If I want to overlay one transparent bitmap over another, how would I do it?

Android :: HttpPost And Byte[ ] ?

Jul 14, 2010

I 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

Mar 23, 2011

Ok so I looked around and didn't see much on this but I'm getting this problem with my code

Code:
public class ListView extends Activity {
String [] test=new String[100];
ListView list;

The problem is this line right here

which gives me a Cannot cast from View to ListView and I checked the xml file and it is a ListView so I don't know what the deal is.

Android : How To Convert SDP Data From Byte Into Object?

Mar 18, 2010

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?
