Is there a way to directly convert a "BLOB"-array into a String[][]-array (on Android?
Thanks very much in advance!

I don't know very much about android, but it's written in Java, yes? So then what you need to do is convert the individual elements of the BLOB array.Ryan Amos– Ryan Amos2011-07-08 15:41:47 +00:00Commented Jul 8, 2011 at 15:41

Yes, it's written in Java. Unfortunately I don't really know how to convert the individual elements of the blob array.deimos1988– deimos19882011-07-08 15:43:48 +00:00Commented Jul 8, 2011 at 15:43

Is there a method for each element to convert it to a string array?Ryan Amos– Ryan Amos2011-07-08 15:50:43 +00:00Commented Jul 8, 2011 at 15:50

Try this: Converting blob array to string array:
BLOB[] blobs = getBlobs(); //fetch it somehow
String[] strings = new String[blobs.length];
for(int i = 0; i < blobs.length; i++)
strings[i] = new String(blobs[i].getBytes(0, blobs[i].length());
return strings;
Converting blob array to string matrix:
BLOB[] blobs = getBlobs(); //fetch it somehow
String[][] strings = new String[blobs.length][];
for(int i = 0; i < blobs.length; i++)
strings[i] = blobToStringArray(blobs[i]);
return strings;

I thought as much, but what about converting a BLOB to a String[][]-array? How do I know which of the bytes belong to which of the array?
Ryan Amos
How are you planning on converting it? You would need to represent a BLOB as an array of strings. I'll post an example above.

Thank you for your example, unfortunately "getBlobs" only returns a byte[]-array, not a blob array as the name would suggest. Certain operations are not available with the byte-array
Ryan Amos
You'll need to find some way to convert a BLOB to a string array. Could you provide some more context on what exactly you're doing?
From what I understand, blobs return bytes. So you want to build a byte array and then build the string from that. This is an example.
Hope it gives you a good start.

My solution doesn't require codingBLOBs to String[][]-arrays anymore, now I am (de-)coding SoapEnvelopes to byte-arrays and vice versa using a method described here: http://androiddevblog.blogspot.com/2010/04/serializing-and-parceling-ksoap2.html
