Calling a method upon completion of progress bar

I need to make an app that sends an SMS message after showing a progress bar in increments of 10. I have the action bar set up and I think I should use AsyncTask? The user is inputing number and message into the main activity, and that's where I have the SendSMS method set up, not sure how to make this work so that it forwards to AsyncTask and calls on that method there.
public class MainActivity extends AppCompatActivity {
private int MY_PERMISSIONS_REQUEST_SMS_RECEIVE = 10;
private static final String SMS_SENT = "SMS_SENT";
private static final String SMS_DELIVERED= "SMS_DELIVERED";
private EditText etPoruka;
private EditText etBroj;
private ProgressDialog progressDialog;
private Context context = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initWidgets();
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.RECEIVE_SMS},
MY_PERMISSIONS_REQUEST_SMS_RECEIVE);
}
private void initWidgets() {
etPoruka = findViewById(R.id.etPoruka);
etBroj = findViewById(R.id.etBroj);
}
#Override

switch (item.getItemId()) {
case R.id.action_send:
MyAsyncTask<Void, Void, Void> updateTask = new MyAsyncTask<Void, Void, Void>(context);
updateTask.execute();
break;
case R.id.action_sent:
Toast.makeText(this, R.string.add_test, Toast.LENGTH_LONG).show();
// BROADCAST RECEIVER ??
break;
case R.id.action_received:

builder.setTitle("Close app");
builder.setMessage("Are you sure?");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {

}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {

ASYNCTASK
public class MyAsyncTask extends
AsyncTask {
private final String DIALOG_MESSAGE = "Sending message";
private ProgressDialog mDialog = null;
private void setDialog(Context context) {
this.mDialog = new ProgressDialog(context);
this.mDialog.setMessage(DIALOG_MESSAGE);
this.mDialog.setCancelable(false);
}
public MyAsyncTask(Context context) {
this.setDialog(context);
}
#Override
protected void onPreExecute() {
this.mDialog.show();
}
#Override
protected Result doInBackground(Params... arg0) {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Result result) {
if (this.mDialog.isShowing()) {
this.mDialog.dismiss();
}
} }

You can create an Interface and implement in your MainActivity.

Android returning NullPointerException when asking findViewById after app is paused

whenever I use the app switcher or the app gets paused in any other way then upon resuming it I will get a NullPointerException when trying to use findViewById in my fragment. The same happens when trying to use getActivity() or anything related to the Main activity. I've tried checking of the fragment is attached or not with isAdded() and it returns true but still gives the error. (Don't mind the way the code looks, I still need to clean it up)
All irrelevant classes and methods are not included (ex. Profanity class).

All view related code must be moved on to onCreateView(). So just place your code to onCreateView in case of fragment and onCreate in case of activity.
For more info just go through https://developer.android.com/guide/components/fragments.html

Crashing because of getView(). Because its not able get the view.
You need to pass the view which hold the view with id R.id.fabSendImage and try calling the view.findViewById(R.id.fabSendImage) to initialize.

Getting user input from a dialog using Mortar + Flow

I'm build my app with Mortar + Flow. I'm trying to figure out the correct way to show a popup that requests some text from the user. I've created this popup class:
public class SavedPageTitleInputPopup implements Popup<SavedPageTitleInput, Optional<String>> {
private final Context context;
private AlertDialog dialog;
public SavedPageTitleInputPopup(Context context) {
this.context = context;
}
#Override public Context getContext() {
return context;
}
#Override
public void show(final SavedPageTitleInput info, boolean withFlourish,
final PopupPresenter<SavedPageTitleInput, Optional<String>> presenter) {
if (dialog != null) throw new IllegalStateException("Already showing, can't show " + info);
final EditText input = new EditText(context);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT);
input.setLayoutParams(lp);
input.setText(info.savedPage.getName());
dialog = new AlertDialog.Builder(context).setTitle(info.title)
.setView(input)
.setMessage(info.body)
.setPositiveButton(info.confirm, new DialogInterface.OnClickListener() {
#Override public void onClick(DialogInterface d, int which) {
dialog = null;
final String newTitle = Strings.emptyToNull(String.valueOf(input.getText()));
presenter.onDismissed(Optional.fromNullable(newTitle));
}
})
.setNegativeButton(info.cancel, new DialogInterface.OnClickListener() {
#Override public void onClick(DialogInterface d, int which) {
dialog = null;
presenter.onDismissed(Optional.<String>absent());
}
})
.setCancelable(true)
.setOnCancelListener(new DialogInterface.OnCancelListener() {
#Override public void onCancel(DialogInterface d) {
dialog = null;
presenter.onDismissed(Optional.<String>absent());
}
})
.show();
}
#Override public boolean isShowing() {
return dialog != null;
}
#Override public void dismiss(boolean withFlourish) {
dialog.dismiss();
dialog = null;
}
}
This class works as expected. It uses the SavedPage to figure out what to display in the dialog and it returns the users input to the PopupPresenter using PopupPresenter#onDismissed when the correct button is pressed.
My problem is writing the PopupPresenter subclass used to present the dialog and process the input. This is what I have right now:
new PopupPresenter<SavedPage, Optional<String>>() {
#Override protected void onPopupResult(Optional<String> result) {
if (result.isPresent()) {
// The user entered something, so update the API
// Oh wait, I don't have a reference to the SavedPage
// that was displayed in the dialog!
}
}
}
As the comments say, I don't have a reference to the SavedPage that was displayed in the dialog. It was stored in the whatToShow field in PopupPresenter, but this field is nulled out right before onPopupResult is called. It seems like I would be unnecessarily repeating myself to keep an additional copy of the SavedPage.

There isn't a lot of documentation yet on PopupPresenter and Popup. The only thing I have seen is a basic example in the sample project. They create a ConfirmerPopup based on data within the Confirmation object. The purpose of the ConfirmerPopup is to capture a boolean decision from the user based on the title/body given to the Confirmation object as seen by the class declaration.
public class ConfirmerPopup implements Popup<Confirmation, Boolean> {
In your case you want to capture additional user inputted text from the user. When PopupPresenter#onPopupResult is called the result object should contain all of the data needed from SavedPageTitleInputPopup. Modify your SavedPageTitleInputPopup as follows
public class SavedPageTitleInputPopup implements Popup<SavedPage, SavedPageResults> {
private final Context context;
private AlertDialog dialog;
public SavedPageTitleInputPopup(Context context) {
this.context = context;
}
#Override public Context getContext() {
return context;
}
#Override
public void show(SavedPage info, boolean withFlourish, final PopupPresenter<SavedPage, SavedPageResults> presenter) {
if (dialog != null) throw new IllegalStateException("Already showing, can't show " + info);
// Create your Dialog but scrape all user data within OnClickListeners
final AlertDialog.Builder builder = new AlertDialog.Builder(context);
//Anything else you need to do... .setView() or .setTitle() for example
builder.setPositiveButton(info.confirm, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface d, int which) {
dialog = null;
//Save data to SavedPageResults
final SavedPageResults results = new SavedPageResults():
presenter.onDismissed(results);
}
});
builder.setNegativeButton(info.cancel, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface d, int which) {
dialog = null;
final SavedPageResults results = new SavedPageResults();
presenter.onDismissed(results);
}
});
dialog = builder.show();
}
#Override public boolean isShowing() {
return dialog != null;
}
#Override public void dismiss(boolean withFlourish) {
dialog.dismiss();
dialog = null;
}
}
Your PopupPresenter doesn't need to know anything about the Dialog's implementation now.
new PopupPresenter<SavedPage, SavedPageResults>() {
#Override protected void onPopupResult(SavedPageResults result) {
if (result.isPresent()) {
updateUi(result.getSavedText());
}
}
}

How to force user to deal with dialog before allowing access to activity? AND What's wrong with my licensing code?

Ok so I recently completed an android app - my first one :D! - and because it is a paid app Google tells me I have to add the licensing stuff. That's fine and dandy, except I've been getting mind f*cked by it for the past five hours. Finally think I understand it a little and got it going, but in testing it in my emulator I come up with two issues:
I'm using the google API for 4.1, as instructed by their handy how-to on the developer console, but nomatter what I always end up coming up with my Connection Error dialog. Code here:
public void dontAllow(int reason) {
if(isFinishing()){
return;
}
displayResults("Access Denied");
if(reason==Policy.RETRY){
showDialog(DIALOG_RETRY);
}else{
showDialog(DIALOG_ERROR);
}
}
public void applicationError(int errorCode) {
dontAllow(0);
}
public void displayResults(String result){
}
And cooresponding dialog being called:
protected Dialog onCreateDialog(int id){
switch(id){
case DIALOG_RETRY:
Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Connection Error: Retry?");
builder.setCancelable(true);
builder.setPositiveButton("Retry", new RetryOnClickListener());
builder.setNegativeButton("Cancel", new CancelOnClickListener());
AlertDialog dialog = builder.create();
dialog.show();
break;
case DIALOG_ERROR:
Builder builder1 = new AlertDialog.Builder(this);
builder1.setMessage("Would you like to purchase Landscape ID! ?");
builder1.setCancelable(true);
builder1.setPositiveButton("Yes!", new BuyOnClickListener());
builder1.setNegativeButton("No.", new CancelOnClickListener());
AlertDialog dialog1 = builder1.create();
dialog1.show();
break;
}
return super.onCreateDialog(id);
}
private final class RetryOnClickListener implements
DialogInterface.OnClickListener{
public void onClick(DialogInterface dialog, int which) {
checker.checkAccess(checkerCB);
}
}
private final class CancelOnClickListener implements
DialogInterface.OnClickListener{
public void onClick(DialogInterface dialog, int which) {
onDestroy();
finish();
}
}
private final class BuyOnClickListener implements
DialogInterface.OnClickListener{
public void onClick(DialogInterface dialog, int which) {
Intent open = new Intent(Intent.ACTION_VIEW);
open.setData(Uri.parse("market://details? id=com.mustaroenterprise.landscapeid"));
startActivity(open);
}
}
My first question: How come it isn't connecting to the server as it should be? I've constructed my testing apratus as instructed by their tutorial. I've gone over it three times!
Second question: When I do launch the app on the emulator, the Connection Error dialog shows up fine. I hit retry, and it works. I hit Cancel, and it kills the app. However, if I simply click anywhere else in the window, outside the dialog, it closes the dialog and the app works normally. That kindof defeats the whole purpose, eh? How do I make that... not so?
Just in case I'm an idiot and the error lies elsewhere, here's the whole class:

For your second question, I would set setCanceledOnTouchOutside to false like so:
Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Connection Error: Retry?");
builder.setCancelable(true);
builder.setPositiveButton("Retry", new RetryOnClickListener());
builder.setNegativeButton("Cancel", new CancelOnClickListener());
AlertDialog dialog = builder.create();
//Add this
dialog.setCanceledOnTouchOutside(false);
dialog.show();

How to display alert dialog in running thread?

I want to display an alert dialog depending upon the property and when the user clicks on the OK button, call the function again to get updated values within the running process.
I have the following code:
importingProgress = ProgressDialog.show(context, getString(R.string.progressNewsListTitle),
getString(R.string.progressProjectListMessage), true);
new Thread(new Runnable() {
public void run() {
try {
app.SetOtherTaskRunning(true);
Ib_clients client = db.Ib_clients_GetById(app.GetCustomerId());
try {
LogManager.WriteToFile("---------------- Getting News from Webservice :- " + DateFormat.getDateTimeInstance().format(new Date()) + "----------------");
CommonFuctions.CreateXml(context, h, client, db, app.GetBookMonth(), app.GetBookQuater(), app.GetBookYear(), Constants.News, app.GetWebServiceLastSyncDate(Constants.ServiceType.NEWS.toString()), Constants.ServiceType.NEWS, null, null, null, null, null);
Return reponse = null;
do {
reponse = CommonFuctions.SendingRequest(context, handler, db);
if (reponse.type.compareTo("warning") == 0) {
h.post(new Runnable() {
public void run() {
AlertDialog.Builder alert = new AlertDialog.Builder(context);
alert.setTitle(context.getString(R.string.information));
alert.setMessage("dsgdgd");
alert.setPositiveButton(context.getString(R.string.logoutDialogOk), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
alert.show();
}
});
}
} while (reponse.type.compareTo("warning") == 0);
} catch (IOException e) {
e.printStackTrace();
}
} catch (Exception e) {
//Log.d(Constants.TAG, e.getMessage());
e.printStackTrace();
}
if (importingProgress != null) {
importingProgress.dismiss();
importingProgress = null;
}
}
}).start();
If response type is warning, then display a message to the user and if the user clicks the OK button , then call CommonFuctions.SendingRequest(context, handler, db) again to get updated values. Until we get a.response type of warning , we need to display an alert dialog to the user and call CommonFuctions.SendingRequest(context, handler, db) again.
Class to return:
public class Return {
public String type;
public String msg;
public boolean isSuccess;
public int client_id; // for getting clientid from server
public int booking_id; // for getting bookingid form server
}

You will have to use handler to display the AlertDialog because UI can be handled by the main thread only.
The other way is to use asyncTask for multiprocessing and then using the onPostExcecute() of asyncTask to display the AlertDialog
Please feel free to ask any further doubts.

Try to run your dialog as below in runonUIthread:
runOnUiThread(new Runnable() {
#Override
public void run() {
AlertDialog.Builder alert = new AlertDialog.Builder(context);
alert.setTitle(context.getString(R.string.information));
alert.setMessage("dsgdgd");
alert.setPositiveButton(context.getString(R.string.logoutDialogOk), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
alert.show();
}
});
