    <p>My app allows a user to select an image from the gallery and upload it to a server. Currently I can display the image but not upload it. I am not getting an error. Below is my code, I hope that it is clear.</p> <pre><code>public void submit_click(View view) { TextView err=(TextView) findViewById(R.id.err); if (thumbnail != null) { // TextView err = (TextView) findViewById(R.id.err); try{ byte[] bitmapdata = imagetoArray(); img = decodeUTF8(bitmapdata); if (updateImage() == true) { Intent myIntent = new Intent(view.getContext(), ProfileActivity.class); startActivityForResult(myIntent, 0); } else { err.setText("Error update image"); } } catch(Exception ex) { err.setText(ex.getLocalizedMessage()); } } } private boolean updateImage() { boolean status = false; TextView err=(TextView) findViewById(R.id.err); String username = SessionManager.getMaps("user"); String postData = "{\"UserImage\":\"" + img + "\",\"UserName\":\"" + username + "\"}"; try { String domain = getString(R.string.domain); HttpClient httpclient = new DefaultHttpClient(); HttpResponse response; HttpPost httppost = new HttpPost(domain + "updateUserImage"); StringEntity se = new StringEntity(postData.toString(), "utf-8"); se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json")); httppost.setEntity(se); httppost.setHeader("Accept", "application/json"); httppost.setHeader("Content-type", "application/json"); response = httpclient.execute(httppost); if (response != null) { HttpEntity r_entity = response.getEntity(); String json = EntityUtils.toString(r_entity); status = Boolean.parseBoolean(json); } } catch (Exception e) { err.setText(e.getLocalizedMessage()); } return status; } private byte[] imagetoArray() { ByteArrayOutputStream stream = new ByteArrayOutputStream(); TextView err=(TextView) findViewById(R.id.err); try{ thumbnail.compress(Bitmap.CompressFormat.PNG, 100, stream); } catch(Exception ex) { err.setText(ex.getLocalizedMessage()); } return stream.toByteArray(); } private String decodeUTF8(byte[] bytes) { String sw=""; TextView err=(TextView) findViewById(R.id.err); try{ sw= Base64.encodeToString(bytes, Base64.NO_WRAP); } catch(Exception ex) { err.setText(ex.getLocalizedMessage()); } return sw; } </code></pre>

    1. COIt would be easier to help you if you could try to isolate the part of your code that seems to be causing the problem - right now it's hard to follow such a large "wall of code".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
