There are a documents https://azure.microsoft.com/en-us/documentation/articles/mobile-services-android-how-to-use-client-library/ that clearly explained how to use the android clinet library to interact with Azure Database for various operations.
I think you can refer to these sample in the document to write own code to implement your needs.
Any other concern, please feel free to let me know.

You have to make changes in your ToDoItem.java
It is the class which corresponds to the table in database.
whenever you make changes to the table in azure.
In ur case, when u are adding new columns to table in azure, say newcol1 and newcol2, You have to add
#com.google.gson.annotations.SerializedName("newcol1")
private boolean newColumnOne;
to your ToDoItem.java file. Only then u could have access to new columns in ToDoActivity.java

public void addItem(View view) {
if (mClient == null) {
return;
}
// Create a new item
final ToDoItem item = new ToDoItem();
item.setText(mTextNewToDo.getText().toString());
item.setComplete(false);
item.setNewColumnOne("dataabc");
item.setNewColumnTwo("dataxyz");
// Insert the new item
AsyncTask<Void, Void, Void> task = new AsyncTask<Void, Void, Void>() {
#Override
protected Void doInBackground(Void... params) {
try {
final ToDoItem entity = addItemInTable(item);
runOnUiThread(new Runnable() {
#Override
public void run() {
if (!entity.isComplete()) {
mAdapter.add(entity);
}
}
});
} catch (final Exception e) {
createAndShowDialogFromTask(e, "Error 3rd");
}
return null;
}
};
runAsyncTask(task);
mTextNewToDo.setText("");
}
just add data through setNewColumnOne(); as i did.
rest of the code should be same.
P.S. dont forget to create getter setter and constructor for TodoItem.Java

You need to Create an Interface with an update method, declare in your Activity and after, pass as parameter to your handler object that gets the data.
Don't forget If you're getting the data in a different Thread, you need to update your views always in an UI Thread or in the Main Thread.
Here Follow some example code:
Your Activity or Fragment
public class MainActivity extends AppCompatActivity
implements UpdateViewCallback { // implement the interface here
private TextView textView = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
textView = findViewById(R.id.textView);
// Pass the interface in your Object that makes the async work
final AsyncWork asyncWork = new AsyncWork(this);
// Running
Thread thread = new Thread(asyncWork);
thread.start();
}
/**
* UpdateViewCallback
* #param result
*/
#Override
public void updateView(final String result) {
// Always update View on MainThread or an UI Thread, or else issues will start to happening
this.runOnUiThread(new Runnable() {
public void run() {
// Check if View is null since you're updating in a thread async
if (textView != null) {
textView.setText(result);
}
}
});
}
}
Your Interface:
public interface UpdateViewCallback {
void updateView(String result);
}
Your Object to handle the Async Work:
public class AsyncWork implements Runnable {
private UpdateViewCallback updateViewCallback;
public AsyncWork(UpdateViewCallback updateViewCallback) {
this.updateViewCallback = updateViewCallback;
}
/**
* Async Work here
*/
#Override
public void run() {
// Do some Work and after update using the interface you passed in the constructor
updateViewCallback.updateView("This is a test");
}
}

P.S. I would share github link but I should give you my personal API key. :(

You need to start the AsyncTask in onCreate() (like you did before) and in finished() you take the results and add them to the Adapter's data list.
Finally, don't forget to call notifyDatasetChanged().
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_movie_details);
// skipping some lines of code here...
mReviewRecycle.setAdapter(mReviewAdapter);
ReviewAsyncTask reviewAsyncTask = new ReviewAsyncTask(this);
reviewAsyncTask.execute();
}
#Override
public void finished(ArrayList<ReviewData> output) {
mReviewList.addAll(output);
mReviewAdapter.notifyDatasetChanged();
}
(Please note that I skipped null checks and error handling for brevity's sake)

In MovieDetails onCreate retrieve current movie ID like you do in displayMovieDetail.
Send that ID to ReviewAsyncTask (you'll need to modify constructor of ReviewAsyncTask)
Retrieve id in ReviewAsyncTask, save it as member variable, and then in doInBackground method send that id to buildReviewUrl as an argument.

From Json To ViewPager

I'm trying to pass data from a json file to a viewpager. I have followed most of the advice previously given to me here but it returns blank, without even crashing.
The four files involved in this:
1. The main fragment:
public class FashionFeed extends Fragment {
ViewPager viewPager;
PagerAdapter adapter;
ThePagerAdapter newdapter;
public static final String URL =
"http://celebirious.com/bey/data/space.json";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_whats_hot, null);
// Locate the ViewPager in viewpager_main.xml
viewPager = (ViewPager) v.findViewById(R.id.pager);
viewPager.setClipToPadding(false);
viewPager.setPadding(4, 0, 4, 0);
int margin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 20 * 2, getResources().getDisplayMetrics());
viewPager.setPageMargin(-margin);
new SimpleTask().execute(URL);
return v;
}
private class SimpleTask extends AsyncTask<String, Void, String> {
#Override
protected void onPreExecute() {
// Create Show ProgressBar
}
protected String doInBackground(String... urls) {
String result = "";
try {
HttpGet httpGet = new HttpGet(urls[0]);
HttpClient client = new DefaultHttpClient();
HttpResponse response = client.execute(httpGet);
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) {
InputStream inputStream = response.getEntity().getContent();
BufferedReader reader = new BufferedReader
(new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) {
result += line;
}
}
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
return result;
}
protected void onPostExecute(String jsonString) {
showData(jsonString);
}
}
private void showData(String jsonString) {
Gson gson = new Gson();
Style style = gson.fromJson(jsonString, Style.class);
List<Space> space = style.getSpace();
newdapter = new ThePagerAdapter(getActivity(), space);
viewPager.setAdapter(newdapter);
}
}
The Adapter extending the Pager:
public class ThePagerAdapter extends PagerAdapter {
List<Space> list;
LayoutInflater inflater;
Context context;
#Override
public int getCount() {
return list.size();
}
#Override
public boolean isViewFromObject(View view, Object object) {
return false;
}
public ThePagerAdapter(Context context,List<Space> list) {
this.list = list;
this.context = context; // red as well
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
// Declare Variables
TextView txtrank;
TextView txtcountry;
TextView txtpopulation;
ImageView imgflag;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.styledeets, container,
false);
// Locate the TextViews in viewpager_item.xml
txtrank = (TextView) itemView.findViewById(R.id.date);
txtcountry = (TextView) itemView.findViewById(R.id.where);
txtpopulation = (TextView) itemView.findViewById(R.id.info);
// Capture position and set to the TextViews
txtrank.setText(list.get(position).getName());
txtcountry.setText(list.get(position).getDates());
txtpopulation.setText(list.get(position).getInfo());
String url = (list.get(position).getAvatarUrl());
imgflag = (ImageView) itemView.findViewById(R.id.photo);
Picasso.with(context)
.load(url)
.placeholder(R.mipmap.ic_launcher)
.error(R.drawable.ic_launcher_gmail)
.fit()
.tag(context)
.into(imgflag);
// Locate the ImageView in viewpager_item.xml
// Capture position and set to the ImageView
//imgflag.setImageResource(flag[position]);
// Add viewpager_item.xml to ViewPager
((ViewPager) container).addView(itemView);
return itemView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
// Remove viewpager_item.xml from ViewPager
((ViewPager) container).removeView((RelativeLayout) object);
}
}
Gson data retreived from jsonschema2pojo.org:
Space.java
public class Space {
#Expose
private String name;
#Expose
private String dates;
#Expose
private String type;
#Expose
private String social;
#Expose
private String info;
#SerializedName("avatar_url")
#Expose
private String avatarUrl;
/**
*
* #return
* The name
*/
public String getName() {
return name;
}
/**
*
* #param name
* The name
*/
public void setName(String name) {
this.name = name;
}
/**
*
* #return
* The dates
*/
public String getDates() {
return dates;
}
/**
*
* #param dates
* The dates
*/
public void setDates(String dates) {
this.dates = dates;
}
/**
*
* #return
* The type
*/
public String getType() {
return type;
}
/**
*
* #param type
* The type
*/
public void setType(String type) {
this.type = type;
}
/**
*
* #return
* The social
*/
public String getSocial() {
return social;
}
/**
*
* #param social
* The social
*/
public void setSocial(String social) {
this.social = social;
}
/**
*
* #return
* The info
*/
public String getInfo() {
return info;
}
/**
*
* #param info
* The info
*/
public void setInfo(String info) {
this.info = info;
}
/**
*
* #return
* The avatarUrl
*/
public String getAvatarUrl() {
return avatarUrl;
}
/**
*
* #param avatarUrl
* The avatar_url
*/
public void setAvatarUrl(String avatarUrl) {
this.avatarUrl = avatarUrl;
}
Lastly, Style.java
public class Style {
#Expose
private List<Space> space = new ArrayList<Space>();
/**
*
* #return
* The space
*/
public List<Space> getSpace() {
return space;
}
/**
*
* #param space
* The space
*/
public void setSpace(List<Space> space) {
this.space = space;
}
}
All the xml data is properly linked 'cause this all works when it is retrieving data locally. What could be wrong?

I figured this out !!!!! How silly of me.
Was
#Override
public boolean isViewFromObject(View view, Object object) {
return false;
}
should have been:
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((RelativeLayout) object);
}

Unable to fix when mocking location on Android

I'm trying to mock the GPS location in my app but as soon as I set mocked location, any app using the google play services is unable to get the location of the device, whether it's the real one or the mocked one.
For instance, if I open Google Map and try to go to my location, i'll get the message
waiting for the location
and nothing will happen. That's the same in my app, the location is never found
my code is the following:
public class MockLocationService {
protected Context context;
// Define a LocationClient object
public LocationClient mLocationClient;
// provider of fake locations
private static final String PROVIDER = "flp";
// TAG for the logs
protected static final String TAG = "MockLocationService";
// intens for states
public static final String MOCK_LOCATION_SERVICE_CONNECTED = "CONNECTED";
public static final String MOCK_LOCATION_SERVICE_DECONNECTED = "DECONNECTED";
public static final String MOCK_LOCATION_SERVICE_FAILED = "FAILED";
public static final String MOCK_LOCATION_SERVICE_SETTING_NOT_ENABLED = "SETTING_NOT_ENABLED";
// current mockLocation
protected static Location currentMockLocation;
public MockLocationService(Context context) {
this.context = context;
// connect to the Google play services
mLocationClient = new LocationClient(context, connectionCallbacks,
onConnectionFailedListener);
}
/**
* Connect to the API to enable mocking the location
*/
public void connect() {
// Connect to Location Services
// ONLY WHEN CALLBACK IS CALLED, ACT
mLocationClient.connect();
}
/**
* Disconnect from the API, stops mocking the location
*/
public void disconnect() {
// terminate aTask
aTask.cancel(true);
currentMockLocation=null;
// disconnect
mLocationClient.disconnect();
}
/**
* Sets the location from a LocationMessage object as the device current
* location
*
* #param location
*/
public void setLocation(LocationMessage location) {
if (location.getLat() == null || location.getLng() == null
|| location.getAccuracy() == null)
return;

newLocation.setLatitude(location.getLat());
newLocation.setLongitude(location.getLng());
newLocation.setAccuracy(1);
newLocation.setTime(System.currentTimeMillis());
newLocation.setBearing(0F);
newLocation.setAltitude(0F);
// set it as a mocked location
this.setMockLocation(newLocation);
// Create a new Location
Log.d(TAG,
"New mocked location: lat: " + location.getLat() + " - lng: "
+ location.getLng() + " - accuracy: "
+ location.getAccuracy());
}
/**
* Sets a Location object as the location for the device
*
* #param mockLocation
* the mocked Location object
*/
protected void setMockLocation(Location mockLocation) {
if (!mLocationClient.isConnected())
return;
currentMockLocation = mockLocation;
if (currentMockLocation==null) {

}
}
// asynchronously send the mock location every second (for GPS)
final RestAsyncTask<Boolean[]> aTask = new RestAsyncTask<Boolean[]>() {
// executes on background thread
#Override
protected Boolean[] doInBackground(Void... lists) {
// set mock location
do {
mLocationClient.setMockLocation(currentMockLocation);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
} while (true);
}
#Override
protected void onPostExecute(Boolean[] result) {
return;
}
};
/**

protected ConnectionCallbacks connectionCallbacks = new ConnectionCallbacks() {
#Override
public void onDisconnected() {
sendIntent(MOCK_LOCATION_SERVICE_DECONNECTED);
}
#Override
public void onConnected(Bundle arg0) {
sendIntent(MOCK_LOCATION_SERVICE_CONNECTED);
// When the location client is connected, set mock mode
try {
mLocationClient.setMockMode(true);
} catch (Exception e) {
sendIntent(MOCK_LOCATION_SERVICE_SETTING_NOT_ENABLED);
}
}
};
/**

*/
protected static void sendIntent(String action) {

}
}
am I missing something?
thanks!

error when setting an onclick to a listview/json

I'm getting a json exception when I try to run my code.
The problem happens on the onclick listener. I'm trying to have the application go to the article of the rss feed on click
Here is the main activity
public class Blocku extends ListActivity {
private RssListAdapter adapter;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
List<JSONObject> jobs = new ArrayList<JSONObject>();
try {
jobs = BlockuReader.getLatestRssFeed();
} catch (Exception e) {
Log.e("RSS ERROR", "Error loading RSS Feed Stream >> " + e.getMessage() + " //" + e.toString());
}
adapter = new RssListAdapter(this,jobs);
setListAdapter(adapter);
}
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
String link = null;
try {
String url = Article.getUrl().toString();
link = adapter.getItem(position).getString(url).toString();
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(link));
startActivity(i);
} catch (JSONException e) {
Context context = getApplicationContext();
CharSequence text = "error";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
e.printStackTrace();
}
}
}
here is the adapter:
public class RssListAdapter extends ArrayAdapter<JSONObject> {
public RssListAdapter(Activity activity, List<JSONObject> imageAndTexts) {
super(activity, 0, imageAndTexts);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Activity activity = (Activity) getContext();
LayoutInflater inflater = activity.getLayoutInflater();
// Inflate the views from XML
View rowView = inflater.inflate(R.layout.image_text_layout, null);
JSONObject jsonImageText = getItem(position);
//////////////////////////////////////////////////////////////////////////////////////////////////////
//The next section we update at runtime the text - as provided by the JSON from our REST call
////////////////////////////////////////////////////////////////////////////////////////////////////
TextView textView = (TextView) rowView.findViewById(R.id.job_text);
try {
Spanned text = (Spanned)jsonImageText.get("text");
textView.setText(text);
} catch (JSONException e) {
textView.setText("JSON Exception");
}
return rowView;
}
}
and the article class
public class Article {
private long articleId;
private long feedId;
private String title;
private String description;
private String pubDate;
private static URL url;
private String encodedContent;
private static String link;
/**
* #return the articleId
*/
public long getArticleId() {
return articleId;
}
/**
* #param articleId the articleId to set
*/
public void setArticleId(long articleId) {
this.articleId = articleId;
}
/**
* #return the feedId
*/
public long getFeedId() {
return feedId;
}
/**
* #param feedId the feedId to set
*/
public void setFeedId(long feedId) {
this.feedId = feedId;
}
/**
* #return the title
*/
public String getTitle() {
return title;
}
/**
* #param title the title to set
*/
public void setTitle(String title) {
this.title = title;
}
/**
* #return the url
*/
public static URL getUrl() {
return url;
}
/**
* #param url the url to set
*/
public void setUrl(URL url) {
Article.url = url;
}
/**
* #param description the description to set
*/
public void setDescription(String description) {
this.description = description;
}
/**
* #return the description
*/
public String getDescription() {
return description;
}
/**
* #param pubDate the pubDate to set
*/
public void setPubDate(String pubDate) {
this.pubDate = pubDate;
}
/**
* #return the pubDate
*/
public String getPubDate() {
return pubDate;
}
/**
* #param encodedContent the encodedContent to set
*/
public void setEncodedContent(String encodedContent) {
this.encodedContent = encodedContent;
}
/**
* #return the encodedContent
*/
public String getEncodedContent() {
return encodedContent;
}
}

JSONException is usually thrown when there are issues with parsing. Check how you are parsing the JSON. this says that you are trying to get a value for a key named "then it lists the site i want"
