Please wait..."); pDialog.setIndeterminate(false); pDialog.setCancelable(false); pDialog.show(); } /** * getting All products from url * */ protected String doInBackground(String... args) { // Building Parameters List&lt;NameValuePair&gt; params = new ArrayList&lt;NameValuePair&gt;(); // getting JSON string from URL JSONObject json = jParser.makeHttpRequest(url_all_products, "GET", params); // Check your log cat for JSON reponse Log.d("All Products: ", json.toString()); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); try { // products found // Getting Array of Products hosps = json.getJSONArray("PA"); // looping through All Products for (int i = 0; i &lt; hosps.length(); i++) { JSONObject c = hosps.getJSONObject(i); // Storing each json item in variable //String id = c.getString(TAG_HID); String name = c.getString(TAG_HOSPITAL); adapter.add(name); } } catch (JSONException e) { e.printStackTrace(); } return null; } /** * After completing background task Dismiss the progress dialog * **/ protected void onPostExecute(String file_url) { // dismiss the dialog after getting all products pDialog.dismiss(); // updating UI from Background Thread runOnUiThread(new Runnable() { public void run() { /** * Updating parsed JSON data into ListView */ Spinner state = (Spinner) findViewById(R.id.spinner1); state.setAdapter(adapter); } }); } } } </code></pre> <p>I try and run my app and i get this error</p> <pre><code>02-22 22:29:48.131: E/AndroidRuntime(1200): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.thenewboston.christian/com.thenewboston.christian.hospitalhttp}: java.lang.IllegalStateException: System services not available to Activities before onCreate() </code></pre> <p>So i move all of this after the oncreate bolck and i still get the same error</p> <pre><code>private ProgressDialog pDialog; JSONParser jParser = new JSONParser(); private static String url_all_products = "http://www.photosbychristian.com/ems/hospitals.php"; //private static final String TAG_HID = "hid"; private static final String TAG_HOSPITAL = "hospital"; JSONArray hosps = null; ArrayAdapter &lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_spinner_item ); </code></pre> <p>And so i have no idea what to do know any help would be greatly appreciated </p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
