Rate my app dialog when the user want to exit my app

I want to change the dialog of exit app with twi choices choice 1 = "rate" and choice 2 = "exit" now i can only show exit or stay dialog but i want to convert it to what i described here is the code :
#Override
public void onBackPressed() {
new AlertDialog.Builder(this)
.setMessage("Are you sure you want to exit?")
.setCancelable(false)
.setNeutralButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
PicSelect.this.finish();
}
})
.setNegativeButton("No", null)
.show();
}
and this the class code `
public class PicSelect extends SherlockActivity {
private GridView photoGrid;
private int mPhotoSize, mPhotoSpacing;
private Itemadapter imageAdapter;
private AdView mAdView;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_picselct);
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#c5d951")));
mAdView = (AdView) findViewById(R.id.adViewad);
mAdView.loadAd(new AdRequest.Builder().build());
mPhotoSize = getResources().getDimensionPixelSize(R.dimen.photo_size);
mPhotoSpacing = getResources().getDimensionPixelSize(R.dimen.photo_spacing);
photoGrid = (GridView) findViewById(R.id.albumGrid);
Model.LoadModel();
String[] ids = new String[Model.Items.size()];
for (int i= 0; i < ids.length; i++){
ids[i] = Integer.toString(i+1);
}
imageAdapter=new Itemadapter(getApplicationContext(), R.layout.photo_item,ids,"CATIMAGE");
photoGrid.setAdapter(imageAdapter);
// get the view tree observer of the grid and set the height and numcols dynamically
photoGrid.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
if (imageAdapter.getNumColumns() == 0) {
final int numColumns = (int) Math.floor(photoGrid.getWidth() / (mPhotoSize + mPhotoSpacing));
if (numColumns > 0) {
final int columnWidth = (photoGrid.getWidth() / numColumns) - mPhotoSpacing;
imageAdapter.setNumColumns(numColumns);
imageAdapter.setItemHeight(columnWidth);
}
}
}
});
photoGrid.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
Log.e("FolderName", Model.GetbyId(position+1).FolderName);
String FolderName=Model.GetbyId(position+1).FolderName;
String CategoryName=Model.GetbyId(position+1).Name;
Intent i=new Intent(PicSelect.this,PicItem.class);
i.putExtra("Folder", FolderName);
i.putExtra("Category", CategoryName);
startActivity(i);
}
});
}
#Override
public void onBackPressed() {
new AlertDialog.Builder(this)
.setMessage("Are you sure you want to exit?")
.setCancelable(false)
.setNeutralButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
PicSelect.this.finish();
}
})
.setNegativeButton("No", null)
.show();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.home, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem menuItem)
{
switch (menuItem.getItemId())
{
case R.id.rateapp:
final String appName = getPackageName();//your application package name i.e play store application url
try {
startActivity(new Intent(Intent.ACTION_VIEW,
Uri.parse("market://details?id="
+ appName)));
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(
Intent.ACTION_VIEW,
Uri.parse("http://play.google.com/store/apps/details?id="
+ appName)));
}
return true;
case R.id.moreapp:
startActivity(new Intent(
Intent.ACTION_VIEW,
Uri.parse(getString(R.string.play_more_apps))));
return true;
default:
return super.onOptionsItemSelected(menuItem);
}
}
}
`
finaly if anyone know how to style the text thank you for your help

.setNegativeButton("Rate App", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent i = new Intent(android.content.Intent.ACTION_VIEW);
i.setData(Uri.parse("market://details?id=[your package name]"));
startActivity(i);
}
})
This will give you a negative option that says Rate App that when clicked opens the market to your app.

Improve your app with this snippet in onBackPressed():
if(isTaskRoot()) {
if (this.lastBackPressTime < System.currentTimeMillis() - 2000) {
toast = Toast.makeText(this, getString(R.string.hinweisBeendeApp), Toast.LENGTH_SHORT);
toast.show();
this.lastBackPressTime = System.currentTimeMillis();
} else {
if (toast != null) {
toast.cancel();
}
super.onBackPressed();
}
}else {
super.onBackPressed();
}

Data from Google Drive's Appdata folder is disappearing

I'm trying to create Spreadsheet file in Google Drive's Appdata folder for my aplication, to use it as a remote database.
Just at the beggining and I'm stuck already. Files are created properly(?), but they seems to be dissapearing after a moment.
I'm doing it like this:
First, on onCreate method I log into my Google Account:
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestScopes(Drive.SCOPE_APPFOLDER)
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this, this)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.addApi(Drive.API)
.addConnectionCallbacks(this)
.build();
signIn();
private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
onActivityResult handles updating UI(displaying user's name and profile pic, all works great on the login/logout side)
Then, in onConnected(Bundle bundle) method, I try to find out if user already has existing database in AppFolder, if not, I'm asking him to create one.
#Override
public void onConnected(Bundle bundle) {
queryDrive();
}
public void queryDrive() {
Query query = new Query.Builder().addFilter(Filters.eq(SearchableField.TITLE, DreamDbSchema.NAME_REMOTE)).build();
Drive.DriveApi.query(mGoogleApiClient, query).setResultCallback(new ResultCallback<DriveApi.MetadataBufferResult>() {
#Override
public void onResult(DriveApi.MetadataBufferResult metadataBufferResult) {
MetadataBuffer buffer = metadataBufferResult.getMetadataBuffer();
if (buffer != null) {
if (buffer.getCount() == 0) {
new AlertDialog.Builder(ListActivity.this).setTitle(R.string.no_database_on_gdrive)
.setMessage(R.string.no_database_on_gdrive_message)
.setCancelable(false)
.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
})
.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Drive.DriveApi.newDriveContents(mGoogleApiClient).setResultCallback(driveContentsCallback);
}
})
.setNeutralButton(R.string.cancel_and_disconnect, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
signOut();
}
})
.show();
} else {
for (int i = 0; i < buffer.getCount(); i++) {
Log.d("DRIVE_FILES: ", buffer.get(i).getTitle());
}
}
} else {
Log.d("DRIVE_BUFFER: ", "null");
}
}
});
}
final private ResultCallback<DriveApi.DriveContentsResult> driveContentsCallback =
new ResultCallback<DriveApi.DriveContentsResult>() {
#Override
public void onResult(DriveApi.DriveContentsResult result) {
if (!result.getStatus().isSuccess()) {
Toast.makeText(ListActivity.this, R.string.error_while_creating_GDrive_file, Toast.LENGTH_SHORT).show();
return;
}
MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
.setTitle(DreamDbSchema.NAME_REMOTE)
.setMimeType("vnd.google-apps.spreadsheet")
.build();
Drive.DriveApi.getAppFolder(mGoogleApiClient)
.createFile(mGoogleApiClient, changeSet, result.getDriveContents())
.setResultCallback(fileCallback);
}
};
final private ResultCallback<DriveFolder.DriveFileResult> fileCallback = new
ResultCallback<DriveFolder.DriveFileResult>() {
#Override
public void onResult(DriveFolder.DriveFileResult result) {
if (!result.getStatus().isSuccess()) {
Toast.makeText(ListActivity.this, R.string.error_while_creating_GDrive_file, Toast.LENGTH_SHORT).show();
return;
}
Toast.makeText(ListActivity.this, getString(R.string.database_created_GD), Toast.LENGTH_SHORT).show();
}
};
Everything seems to be working good for about 10 minutes. In another activity I can successfully remove this file like this:
#Override
public void onClick(View v) {
if (!mGoogleApiClient.isConnected()) {
Toast.makeText(SettingsActivity.this, R.string.not_loged_in, Toast.LENGTH_SHORT).show();
} else {
Drive.DriveApi.getAppFolder(mGoogleApiClient).listChildren(mGoogleApiClient).setResultCallback(new ResultCallback<DriveApi.MetadataBufferResult>() {
#Override
public void onResult(final DriveApi.MetadataBufferResult metadataBufferResult) {
Log.d("DRIVE_FILES: ", String.valueOf(metadataBufferResult.getMetadataBuffer().getCount()));
for (int i = 0; i < metadataBufferResult.getMetadataBuffer().getCount(); i++) {
final int j = i;
DriveId fileId = metadataBufferResult.getMetadataBuffer().get(i).getDriveId();
Drive.DriveApi.getFile(mGoogleApiClient, fileId).delete(mGoogleApiClient).setResultCallback(new ResultCallback<Status>() {
#Override
public void onResult(Status status) {
if (status.isSuccess()) {
Toast.makeText(SettingsActivity.this, R.string.database_removed_GD, Toast.LENGTH_SHORT).show();
}
}
});
}
}
});
}
}
and it also prints in log "1" for a while. But give it a ten minutes or so, and I'm once again prompted to create database, because it finds Appdata folder to be empty.

Android billing consuming items

I am trying to have an consumable item for my app.
i currently use this code:
private void BuyManager() {
mHelper.flagEndAsync();
mHelper.launchPurchaseFlow(this, "jm.admin", 1011, new IabHelper.OnIabPurchaseFinishedListener() {
#Override
public void onIabPurchaseFinished(IabResult result, Purchase info) {
AlertDialog.Builder succces = new AlertDialog.Builder(MainActivity.this);
int proccesed = 1;
try {
proccesed=mservice.consumePurchase(3,getPackageName(), "inapp:"+getPackageName()+":jm.admin");
} catch (RemoteException e) {
e.printStackTrace();
}
String succs = "nee";
if (proccesed==0){
succs = "ja";
}
succces.setMessage("We checken uw aankoop Aankoop gegevens: " + result + " Aankoop succesvol: "+succs);
succces.setPositiveButton("Oke", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
succces.show();
if (result.isSuccess()) {
AlertDialog.Builder succces2 = new AlertDialog.Builder(MainActivity.this);
succces2.setMessage("Uw aankoop is voltooid");
succces2.setPositiveButton("Oke", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
succces2.show();
}
}
});
}
but when i buy the item it not consumed at all and it haves the code 7 response (item already bought).
Whats wrong with my code?

Remember checkbox within a dialog

I try to remember the checkbox within a dialogue but in comparison remember == false the variable remember still has not changed its value. In the loop is iterated as many times as the size of lelements_tmp before call showDialogSameFile() so neither can I use the variable remember within the loop. How can I do it? Thanks in advance.
private boolean remember = false;
// in the program
// add files to List lelements_tmp
while (i < lelements_tmp.size()) {
File fto = new File(lelements_tmp.get(i).getFile());
String to = null;
try {
to = fto.getCanonicalPath();
} catch (IOException e) {
e.printStackTrace();
}
if (fto.exists()) {
showDialogSameFile(fto, to, i);
i++;
continue;
}
thread(i);
i++;
}
private void showDialogSameFile(File f, String to, final int i) {
TextView title = null;
if (f.isDirectory())
title = this.getTitle("The directory " + to + " already exists. Do you want to replace the contents?");
else if (f.isFile())
title = this.getTitle("The file " + to + " already exists. Do you want to replace it?");
String[] item = {"Apply to all"};
AlertDialog ad = new AlertDialog.Builder(context)
.setCustomTitle(title)
.setMultiChoiceItems(item, null,
new DialogInterface.OnMultiChoiceClickListener() {
#Override
public void onClick(DialogInterface dialog, int indexSelected, boolean isChecked) {
if (isChecked)
remember = true;
}
})
.setPositiveButton("Aceptar",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
thread(i);
}
})
.setNegativeButton("Cancelar",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
})
.create();
if (remember == false)
ad.show();
}

I've had to refactor the code a bit, but basically with this work. It's necessary to call to the method from non-UI thread. Based on this response https://stackoverflow.com/a/11369224/5089855
import android.app.Activity;

import android.content.DialogInterface;

}
private boolean showDialogMismoArchivo() {
context.runOnUiThread(new Runnable() {

String[] item = {"Apply all"};
AlertDialog ad = new AlertDialog.Builder(context)
.setTitle("¿Reemplazar?")
.setMultiChoiceItems(item, null,

remember = true;
else
remember = false;
}

.setNegativeButton("Cancel",

}
})
.create();
ad.show();
}
});
try {
mutex.acquire();
} catch (InterruptedException e) {
e.printStackTrace();
}
return remember;
}
}

How to use return value of a method in a another class in android

I'm still new to Java and in Android programming so I'm a bit confused in some programming methods. I just want to ask, how do I use return value of method match_eye() in another class ?. I just want to use mmres.minVal and mmres.maxVal values in a another class (FdActivity) and display these values in my activity class.can anyone show me the code to do this :) thanks

As far as I understand you have Activity where you want to show two values which you want to get from another class. You can't return two values from one function that's why I suggest you to create your own Object which will hold these values and you can return your custom object from match_eye() for example and get your values from your Activity. Here is example code:
MyCustomObject.java
public MyObject{
private int mFirstValue;
private int mSecondValue;
// public constructor
public MyObject(int firstValue, int secondValue){
this.mFirstValue = firstValue;
this.mSecondValue = secondValue;
}
// first value getter
public int getFirstValue(){
return mFirstValue;
}
// second value getter;
public int getSecondValue(){
return mSecondValue;
}
}
and in your match_eye() you can do something similar to this:
public MyObject match_eye(Rect area, Mat mTemplate,int type){
//do your calculations here ...
int firstValue = 0; // get first value
int secondValue = 0; // get second value
return new MyObject(firstValue, secondValue);
}
and in your Activity you just need to call :
MyObject mCurrentObject = FdView.match_eye(/*params*/); // static call as example
if(mCurrentObject != null){
int myFirstValue = mCurrentObject.getFirstValue();
int mySecondValue = mCurrentObject.getSecondValue();
// Show these values in your Activity.
}

Take object of that class in which you defined your method into your second activity and use like below code:
testing t1 = new testing();
double returnval = t1.match_eye(yourarea, youmTemplate,yourtype);
System.out.println(returnval);
For sending value using Intent:
Intent i = new Intent(context,MainActivity.class)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra("var", returnval)
context.startActivity(i);
