java - How to reliably take a photo in Android? -


i trying take photo in android app, convert jpeg, upload web service. far got following:

private static final int camera_request = 1888; private void takephoto() {     intent cameraintent = new intent(android.provider.mediastore.action_image_capture);     startactivityforresult(cameraintent, camera_request); }  @override protected void onactivityresult(int requestcode, int resultcode, intent data) {     super.onactivityresult(requestcode, resultcode, data);      switch (requestcode) {         case camera_request:             bitmap photo = (bitmap) data.getextras().get("data");              bytearrayoutputstream bos = new bytearrayoutputstream();             photo.compress(bitmap.compressformat.jpeg, 90, bos);             byte [] bitmapdata = bos.tobytearray();              char [] dataaschar = new string(bitmapdata ).tochararray();              url url = new url("http://www.foo.com/bar);             urlconnection conn = url.openconnection();             conn.setdooutput(true);             conn.setrequestproperty("content-type", "application/octet-stream");              outputstreamwriter wr = new outputstreamwriter(conn.getoutputstream());             wr.write(dataaschar);             wr.flush();              // response             bufferedreader rd = new bufferedreader(new inputstreamreader(conn.getinputstream()));             string line;             while ((line = rd.readline()) != null) {                 // process line...             }             wr.close();             rd.close();              break;     } }

the seems work, e.g. doesn't crash. in bitmap photo variable. compress using bytearrayoutputstream , becomes 5103 bytes (in buffer). convert char array (so can sent) , char array becomes 4758 elements. not sure why (probably line char [] dataaschar = new string(data).tochararray();). , of course once image makes on other side it's corrupted.

what missing here?

edit. per suggestion @digitaljoel, chucked outputstreamwriter , replaced 

outputstream os = conn.getoutputstream(); os.write(data);

new string(bitmapdata ).tochararray() seems bad idea me. don't think can expect bytes jpeg shoved string without corruption happening. so, why not write bytes outputstream instead of wrapping in outputstreamwriter?

i want read-only access user's google contacts. there stackoverflow member wanted this, , received following answer : yes, there is, use https://www.googleapis.com/auth/contacts.readonly scope , "view contacts". this exchange reference read-only access google contacts can find using google. simply using access token obtained attempt read usual google contacts api (i.e. https://www.google.com/m8/feeds ) fails insufficient permissions. similarly, using google contacts api on new target fails 404 errors (for example https://www.googleapis.com/auth/contacts.readonly/default/full ). is there documentation anywhere on how use api, or permissible way access google contacts api full read-write access?
