There what I am trying to do :
I am calling a WebService that send me back an image.
I get it from the entity.getContent() method.
Further in my code I try to use de BitmapFactory.decodeByteArray(myImage, 0, myImage.lenght) but the Bitmap that it returns me is always null
Does someone have an idea ?

I am using the previewCallback from the camera to try and grab images. Here is the code I am using

The last line gives a null pointer exception, why is BitmapFactory.decodeFile returning null? I can verify that the file is getting saved correctly as I can pull it using adb and see the png displaying properly.
I get a OutOfMemoryError at BitmapFactory.decodeByteArray when bitmap size is large; Following is the code snippet:

I am working on an app that displays photos which are downloaded from Flickr. I obtain a Bitmap object from a byte array, which in turn is read from the relevant Flickr URL, as follows: Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length); The problem is that the resulting bitmap is pixelated and I can't figure out why. To demonstrate, here is an example of a picture created via BitmapFactory.decodeByteArray versus the original picture obtained directly from the relevant Flickr URL:...
View 6 Replies View RelatedI'm using the Camera.PreviewCallback.onPreviewFrame to try to generate a bitmap from the byte array passed to that method. If I use BitmapFactory.decodByteArray it returns null. I'm assuming that the array is correctly formatted since the data just comes right from the camera, so what could the problem be?

We have a SOAP webservice that is used for an iPhone application, but it is possible that we need an Android specific version or a proxy of the service, so we have the option to go with either SOAP or JSON. I have a few concerns about both methods:
SOAP solution:
Is it possible to generate java source code from a WSDL file, if so, will it include some kind of proxy
class to invoke the webservice and will it work in the Android environment at all? Google has not provided any SOAP library in Android, so i need to use 3rd party, What about the performance/overhead with parsing and transmitting SOAP xml over the wire versus the JSON solution?
JSON solution:
There is a few classes in the Android sdk that will let me parse JSON, but does it support generic
parsing, like if I want the result to be parsed as a complex type? Or would I need to implement that
myself? I have read about 2 libraries before here on Stackoverflow, GSON an Jackson. What is the difference performance and usability (from a developers perspective) wise? Do you have any experince with either of those libraries?
Playing around with the UI and SQLLite for a while and it looks pretty good to me . We have a requirement that for the App that all the questions would be coming from the server through REST / Web service which would be displayed on the App..
say for e.g if there are 4 questions
1) Enter your Name -- Text Box
2) Did you sleep well last night -- YES / NO
3) How many hours did you sleep - Text Box
4) How did you hear about us -- Drop down
So the requirement is that the Questions would be displayed on the App after doing a SYNC with the server during the SYNC with the server the Questions would be downloaded from the SERVER through REST / Web service..if the phone is not connected then pull the questions from the Database...
These questions are simple questions and they change quite often and we have a similar app which is there for iphone which does this ....
