I'm able to edit & save data from one Activity(EditActivity.java), but the updated data doesn't display(or carried over) to the next Activity(ViewActivity.java) when click Save button. I can see the changes on the EditText fields if go back to the EditActivity page.
EditActivity.java
btnSave.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
// starting background task to update request
new SaveRequestDetails().execute();
}
});
class SaveRequestDetails extends AsyncTask<String, String, String> {
protected String doInBackground(String... args) {
// getting updated data from EditTexts
String request_title = txtTitle.getText().toString();
String request_date = txtSdate.getText().toString();
String reqEndDate = txtEdate.getText().toString();
String hours = txtHours.getText().toString();
String reason = txtReason.getText().toString();
String explanation = txtExp.getText().toString();
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair(TAG_ID, request_id));
params.add(new BasicNameValuePair(TAG_TITLE, request_title));
params.add(new BasicNameValuePair(TAG_SDATE, request_date));
params.add(new BasicNameValuePair(TAG_EDATE, reqEndDate));

setResult(100, i);
finish();
} else {

} catch (JSONException e) {

Your headline says that, that onActivityResult() does not get called.
Use startActivityForResult(in, 55) instead of startActivity(in)
//EDIT:
By the way, checking the result code should by done using the RESULT_OK / RESULT_CANCELED constants. You might also consider checking the request code (in my example code it would be 55)

Im creating an intent to an activity by clicking on a button which should open google places, but it closes again really fast and says no location selected, and returns to the main activity, and then nothing happens if i click again.
My api should be fine, I have checked that it's the correct SHA1-fingerprint thats connected to the api key.
The result code is 2
It worked earlier in the activity before this one, but I needed it to open when i click on a button instead, and now when I try to open this new activity as an intent it wont work.
public class MapActivity extends AppCompatActivity {
int PLACE_PICKER_REQUEST = 1;
int status;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_events);
status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (status != ConnectionResult.SUCCESS) {
if (GooglePlayServicesUtil.isUserRecoverableError(status)) {
GooglePlayServicesUtil.getErrorDialog(status, this,
100).show();
}
}
if (status == ConnectionResult.SUCCESS) {
int PLACE_PICKER_REQUEST = 199;
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
Context context = this;
try {
startActivityForResult(builder.build(context), PLACE_PICKER_REQUEST);
} catch (GooglePlayServicesRepairableException e) {
e.printStackTrace();
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
System.out.println("Result code: " + resultCode);
System.out.println("Request code: " + requestCode);
if (requestCode == 100) {
status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
}
if (requestCode == 199) {
//process Intent......
if (data != null) {
Place place = PlacePicker.getPlace(data, this);
String toastMsg = String.format("Place: %s", place.getName());
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
} else {
String toastMsg = ("No location selected.");
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
}
}
}
}
This is from the intent which create the new intent to maps
public void onClick(View view) {
Intent i = new Intent(this, MapActivity.class);
startActivity(i);
}
I think its happening because of you are using old method of getPlace
try to swap the arguments, by changing it from:
Place place = PlacePicker.getPlace(data, this);
to
Place place = PlacePicker.getPlace(getContext(), data);
Update #2
Enable Google places API in the developer console and add these lines to AndroidManifest
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="ADD_YOUR_API_KEY_HERE" />
Update #3
after some search, it looks like there is others having same issue. Look at these links:

I'm just a beginner and I have no idea what is causing the error. I have searched the site for solutions but it seems that this error is code specific. Any help is appreciated.
This happen because you have not initialize your ProgressDialog properly or you do not close your progress dialog properly. Make sure that in onPause() you call pDialog.dismiss(); And also initialize in this way.
Make object of Context and initialize it in onCreate(); as mContext=YourActivity.this
pDialog= ProgressDialog.show(mContext);
Problem is in do in background, check your else condition you are starting another activity from there so just put pDialog.dismiss(); before you start another activity
Reason behind this crash is you dialog is still showing and you are changing Activity so its showing WindowLeaked error
As you doInBackground will not allow to hide dialog you can hide it in onPause() method it will also work
Not sure if this is know behavior or what, but here's the logical flow:
User opens app
Pulls nav drawer out, clicks profile pic to change it
Gallery intent pops up, user picks image, everything works fine
Subsequent attempt to open gallery works fine, upon choosing picture, application hangs
onResume() is not called, neither is onActivityResult(). I even commented out all the code in onActivityResult and it still happens. Any ideas what would cause this?
Here is code from onCreate() in the main activity
ImageButton profilePictureButton = (ImageButton) findViewById(R.id.change_profile_picture);
profilePictureButton.requestFocus();
profilePictureButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, 1);
}
});
And here's the handler:
#Override
protected void onActivityResult(int requestCode, int resultCode, final Intent data) {
if(resultCode == RESULT_OK) {
if(requestCode == 1) {
ImageView view = ((ImageView) findViewById(R.id.nav_profile_picture));
if(data != null) {
/*Picasso.with(this).load(data.getData()).into(view);
UsersCache.getInstance().GetUser("", new Response.Listener<UserItem>() {
#Override
public void onResponse(UserItem response) {
String pictureName = response.username + UUID.randomUUID().toString();
String url = "<redacted>";
JSONObject requestBody = new JSONObject();
try {
requestBody.put("profilePicture", "<redacted>/media/profile_pictures/" + pictureName);
} catch(JSONException e) {
e.printStackTrace();
return;
}
FlareJsonObjectRequest request = new FlareJsonObjectRequest(Method.POST, url, requestBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
String tet = null;
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
String tet = null;
}
});
new AmazonS3Uploader(data.getData(), "profile_pictures/" + pictureName);
VolleyQueue.getInstance().getQueue().add(request);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
String tet = null;
}

I think you are missing the read access permission in Manifest -

I am developing an android app in which , a sigin , and signup option is there . when a new user enters to the application for first time he needs to signup.. when he presses the sigin option he is directed to the account creation page.where he needs to gve the username,password and mobile number. all these three values are stored in sqlite ( applications memory ) and a passcode is created and send to the mobile number provided by user. and next page is registration page, where users username and password is checked along with the passcode which he recieved. This process I did to verify the mobile number. So my problem is if once the user created the account and go back to signin option and enter the username and password .. he is directing to the applications first page... because when account creation process is done his details are saved in the applications databse for verification. so user dont need to verify the passcode.. so is there any way to make the signin button view only after a registration process.. or something like that ... I am posting here the siginactivity, signupactivity and register activity.. pls check it and if found any error pls help me...

I understood your problem ... You are saving your signup details in sqlite so when user entering username and password it is saved in sqlite and next step is registration process where user has to enter the secret code.. But as as username and password is saved in sqlite user can press back button and go back and login with username and password and avoid registration process...
Here you can do something like this. use shared preference
for ex:In registration page after successful registration give value l.
SharedPreferences set = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor ed = set.edit();
ed.putString("l", "l");
ed.commit();
and check in your home page whether the value is l or not if value is l only then make your signin button visible. You can use something like this for making the button invisible.
btn3.setVisibility(View.INVISIBLE);
btn4.setVisibility(View.INVISIBLE);
This is the ArrayList page that opens as a result page after update and save. I guess I would need to somehow refresh so that it reflects the changes on the UI. I've tried to call notifyDataSetChanged() but no luck with my level of experience. Could someone kindly show how to implement it please?
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.all_requests);
requestsList = new ArrayList<HashMap<String, String>>();
new LoadAllRequests().execute();
ListView list = getListView();
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String request_id = ((TextView) view.findViewById(R.id.request_id)).getText().toString();
Intent in = new Intent(getApplicationContext(),
ViewRequestActivity.class);
in.putExtra(TAG_ID, request_id);
startActivityForResult(in, 100);
}
});
}
// Response from ViewRequestActivity when delete a request reload this page again
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// if result code 100
if (resultCode == 100) {
Intent intent = getIntent();
finish();
startActivity(intent);
}
}
class LoadAllRequests extends AsyncTask<String, String, String> {
protected String doInBackground(String... args) {
List<NameValuePair> params = new ArrayList<NameValuePair>();
JSONObject json = jParser.makeHttpRequest(url_all_requests, "GET", params);
Log.d("All Requests: ", json.toString());
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
requests = json.getJSONArray(TAG_REQUESTS);
for (int i = 0; i < requests.length(); i++) {
JSONObject c = requests.getJSONObject(i);
String request_id = c.getString(TAG_ID);
String request_title = c.getString(TAG_TITLE);
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_ID, request_id);
map.put(TAG_TITLE, request_title);
requestsList.add(map);
}
} else {
Intent i = new Intent(getApplicationContext(),
NewRequestActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
You need to create an adapter for your ListView. The adapter is what feeds data to it for displaying. I would recommend you reading through this tutorial:
http://www.vogella.com/articles/AndroidListView/article.html
So once you have created your adapter and then called lv.setAdapter(<adapter>), you can then call <adapter>.notifyDataSetChanged(). This will tell the adapter that it needs to refresh itself.
You can use notifyDataSetChanged() method for your adapter.Wherever you want to update your listview you can use in following manner.
adapter.notifyDataSetChanged();
