View 2 Replies View RelatedI want to convert a image into Base64 format and send it to server. I have one Base64 class which accept byte array and return a string.I am sending image into chunks of data.I am creating creating one chunk of 100kb. If image is less than 100 kb then image is uploaded on server, but if it is greater than 100kb (i.e when it requires more than one chunk) then it will not uploaded. I think it is because I am converting image into Base64 in parts and on server it decode it only in one shot. Now I want to send a image for conversion of Base64 only in one chunk. But if image is too large then it throw OutOfMemoryException (Obviously after all it is mobile having very limeted resources).
My code is as follows:

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 am using a html parser called jsoap, to load and parse html files. The problem is that the webpage I'm scraping is encoded in ISO-8859-1 charset while Android is using UTF-8 encoding(?). This is results in some characters shows up as question marks. So now I guess I should convert the string to UTF-8 format. Now I have found this Class called CharsetEncoder in the Android SDK, which I guess could help me. But I can't figure out how to implement it in practice, so I wonder if could get som help with by a practical example.

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 just got a Droid, and after having used it for a while, I felt like I wanted to make a program for it. The program that I am trying to make calculates the actual storage capacity of secondary storage mediums. The user select from a list of units that ranges from KB to YB and the size the entered gets put into a formula depending on the chosen unit.However, there is a bit of a problem with the program.From my testing,I have narrowed it down to the fact that the user's selection is not really being obtained from the spinner.Everything I look up seems to point me to a method quite similar to how it works in J2SE, but it does nothing. How am I actually supposed to get that data?
