I think I can help with the part about reading the file.
My intent and startActivity code looks similar:
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.setType("image/*");
startActivityForResult(i,4);
The result is passed in onActivityResult as the intent:
onActivityResult (int requestCode, int resultCode, Intent data)
To turn that Intent data into a file that I can read, I make it into an
AssetFileDescriptor with this line:
AssetFileDescriptor thePhoto =
getContentResolver().openAssetFileDescriptor(data.getData(), "r");
Perhaps there are other ways to do this, but I worked this out via the
documentation and it works for me.
Once you have the AssetFileDescriptor, you can create an inputstream and
read the file or an outputstream to write the file.
I'm reading the file so I say: thePhoto.createInputStream()
See
