Hey @zeeshan_niazi,

Would you be able to share some of the code that you already have that isn’t working? I would like to help you troubleshoot, but first want to find out where we stand.

Best,

as i was working in couchbase server, so i used the same technique that i was using in couchbase server, i convert image in bytes and than save it in document. like is below:

BufferedImage image = ImageIO.read(new File(file.getPath()));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(image, “png”, baos);
Document img_doc = db.getDocument(“image”);
Map<String, Object> img_properties = new HashMap<String, Object>();
img_properties.put(“image”, bytes);
img_doc.putProperties(img_properties);

protected void onActivityResult(int requestCode, int resultCode, Intent data){
InputStream stream = null;
if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK) {
InputStream stream = getContentResolver().openInputStream(data.getData());
// Add or update an image to a document as a JPEG attachment:
Document doc = database.getDocument(“Robin”);
UnsavedRevision newRev = doc.getCurrentRevision().createRevision();
newRev.setAttachment(“photo.jpg”, “image/jpeg”, stream);
newRev.save();
}
}
this code shows an error an able to find getContentResolver()
i searched for jar, that any jar contains this class or method. but unable to find.
kindly help.

Hi @zeeshan_niazi,

I believe that getContentResolver() is Android method. http://developer.android.com/reference/android/content/Context.html#getContentResolver() You need to replace this line with your code to obtain InputStream.

Following is our ToDo Lite sample for Android. I believe this snippet also helps you.
