Firebase Nullpointer exception

I am trying to retrieve user email from Users and then use it to get data from other firebase database nodes like the Shared_With node. But for some odd reason I am getting Null pointer exceptions. I have no idea why email is either not being retrieved or being set to null. Here is my class where I am doing all of this:

Here is my Logcat:

logcat2
Here is my database structure:

You forgot to initialize your mAuth
mAuth = FirebaseAuth.getInstance();
This will make emaill null

I suspect emaill is empty or null in this statement:
mdShare.child(emaill).addValueEventListener(new ValueEventListener() {...}
Look at your log output to see what is logged for these statements:
System.out.println("Email add:" + emaill);
...
System.out.println(emaill+"HEH");
Also look at the output from these statements. Perhaps there is no signed-in user, so getCurrentUser() is returning null. It is also possible that there is a user, but there is no email address in his/her profile. And as #Indra correctly points out, you haven't initialized mAuth.
try {
emaill = mAuth.getCurrentUser().getEmail();
emaill = emaill.replace(".", "<");
System.out.println("Email add:" + emaill);
}catch(NullPointerException n){
System.out.println(n.getMessage());
}

Class Context from other class android

I have two Classes (MainActivity & Dialogs)
I am trying to call the Dialogs Class (which as a context) to the MainAcitivity;
I have tried
Dialogs WorkOnDialog = (Dialogs)context;
WorkOnDialog.WorkOnSavedDialog();
This is my MainAcitivty
public class MainActivity extends AppCompatActivity {
Context context = this;
boolean WorkOn = false;
boolean WorkOff = false;
Dialogs WorkOnSaveDialog;
// Dialogs WorkOnSaveDialog = (Dialogs) context;
// Dialogs WorkOffSaveDialog = (Dialogs)context;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
//Press Work On Button
public void WorkOnClicked(View v) {
//Creates ImageButton var for ActionListener
ImageButton WorkOnClicked = (ImageButton) findViewById(R.id.WorkOn);
WorkOnClicked.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Gets & Sets Date, Filename, Data Content
// Creates Output Stream to save to file
String nowDate = DateFormat.getDateTimeInstance().format(new Date());
String filename = "WorkOnFile";
String string = nowDate + " Work On";
FileOutputStream outputStream;
File file = new File(Environment.getDataDirectory(), filename);
System.out.println("Work On Button CLicked");
try {
outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
outputStream.write(string.getBytes());
outputStream.close();
System.out.println("!Wrote " + string + " !");
System.out.println("Wrote at " + file);
WorkOn = true;
} catch (Exception e) {
e.printStackTrace();
}
Dialogs WorkOnDialog = (Dialogs)context;
WorkOnDialog.WorkOnSavedDialog();
}
});
}
//Press WorkOff Button
public void WorkOffClicked(View v) {
//Creates ImageButton var for ActionListener
ImageButton WorkOffClicked = (ImageButton) findViewById(R.id.WorkOff);
WorkOffClicked.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Gets & Sets Date, Filename, Data Content
// Creates Output Stream to save to file
String nowDate = DateFormat.getDateTimeInstance().format(new Date());
String filename = "WorkOffFile";
String string = nowDate + " Work Off";
FileOutputStream outputStream;
File file = new File(Environment.getDataDirectory(), filename);
System.out.println(" Work Off Button CLicked");
try {
outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
outputStream.write(string.getBytes());
outputStream.close();
System.out.println("!Wrote " + string + " !");
System.out.println("Wrote at " + file);
WorkOn=false;
} catch (Exception e) {
e.printStackTrace();
}
// WorkOffSaveDialog.WorkOffSavedDialog();
}
});
This is my Dialogs class
public class Dialogs extends AppCompatActivity {
public Context context = this;
public void WorkOnSavedDialog() {
new AlertDialog.Builder(context)
.setTitle("Work On File Saved")
.setMessage("[Displaying for Test] Work On File Saved")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}
public void WorkOffSavedDialog() {
new AlertDialog.Builder(context)
.setTitle("Work Off File Saved")
.setMessage("[Displaying for Test] Work Off File Saved")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}
}
Can anyone explain to me why I am unable to call this "Dialogs" Class within the main method?
I have searched about calling methods with context, and everything I found did not work out, what exactly is going wrong and why?

You need to make constructor to your Dialog class and pass the MainActivity context to this constructor :
public class Dialogs extends AppCompatActivity {
public Context context;
public Dialogs(Context context) {
this.context = context;
}
public void WorkOnSavedDialog() {
new AlertDialog.Builder(context)
.setTitle("Work On File Saved")
.setMessage("[Displaying for Test] Work On File Saved")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}
public void WorkOffSavedDialog() {
new AlertDialog.Builder(context)
.setTitle("Work Off File Saved")
.setMessage("[Displaying for Test] Work Off File Saved")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}
}

Notify users for new version of Android app

I want to show a notification or dialog (when app opens) if the current installed app is not the Updated Version (available in play store).
How can i do that?

add this dependency to your gradle file..
com.github.rampo.updatechecker:library:2.1.8
And try this code in your Activity..
public static String NEW_VERSION = "1.1.0";
public void checkForAppUpdate () {
try {
if (!((Activity) context).isFinishing()) {
UpdateChecker.setNotice(Notice.NOTIFICATION);
UpdateChecker.setNoticeIcon(R.drawable.your_notification_logo);
String s = "Hello User, New version of this application is now available on play store.";
if (Comparator.isVersionDownloadableNewer((Activity) context, NEW_VERSION)){
SharedPreferences pref = context.getSharedPreferences(UpdateChecker.PREFS_FILENAME, 0);
boolean b = pref.getBoolean(UpdateChecker.DONT_SHOW_AGAIN_PREF_KEY + NEW_VERSION, false);
if (!b) {
displayAlertDialogforPlayStore(context, "Update Available", s);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
And Function displayAlertDialogforPlayStore() is...
public void displayAlertDialogforPlayStore(final Context context, String title,
String message) {
try {
final AlertDialog.Builder alert = new AlertDialog.Builder(context);
alert.setIcon(R.drawable.your_notification_logo);
if (title != null) {
alert.setTitle(title);
}
alert.setMessage(message);
alert.setPositiveButton("Update Now", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
final String appPackageName = context.getPackageName();
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=" + appPackageName));
context.startActivity(intent);
}
});
alert.setNegativeButton("Later", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
alert.show();
} catch (Exception e) {
e.printStackTrace();
}
}
This code display both notification and alertDailog for update.

You can use Firebase notifications as described here. You can choose your segment (e.g. app version) as described here.

How I get the default ringtone list in android on programmatically?

I am android developer and want to create a android apps.In this apps ,it needed to show the android default ringtone list.But i can not show it.How to get the android default ringtone list .
Please help to me.

I have upvote Yuichi's answer but it did not completely work for me. For each ringtone I was getting same URI (different title thought). Following code worked for me -
public void listRingtones() {
RingtoneManager manager = new RingtoneManager(this);
manager.setType(RingtoneManager.TYPE_RINGTONE);
Cursor cursor = manager.getCursor();
while (cursor.moveToNext()) {
String title = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX);
Uri ringtoneURI = manager.getRingtoneUri(cursor.getPosition());
// Do something with the title and the URI of ringtone
}
}
You can see the working app on playstore.

This question/answer should provide what you're after: How to bring up list of available notification sounds on Android
You'll just need to swap out the RingtoneManager.TYPE_NOTIFICATION for RingtoneManager.TYPE_RINGTONE

You can get the list of Ringtones using RingtoneManager
public void listRingtones() {
RingtoneManager manager = new RingtoneManager(this);
manager.setType(RingtoneManager.TYPE_RINGTONE);
Cursor cursor = manager.getCursor();
while (cursor.moveToNext()) {
String title = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX);
String uri = cursor.getString(RingtoneManager.URI_COLUMN_INDEX);
// Do something with the title and the URI of ringtone
}
}

Get a List of All ringTones with default ringtones in a list :
public static Map<String, Uri> getRingtones(Activity activity) {
RingtoneManager manager = new RingtoneManager(activity);
manager.setType(RingtoneManager.TYPE_RINGTONE);
Cursor cursor = manager.getCursor();
Map<String, Uri> list = new LinkedHashMap<>();
String title = "Set to Default";
Uri defaultRingtoneUri = RingtoneManager.getActualDefaultRingtoneUri(activity, RingtoneManager.TYPE_RINGTONE);
list.put(title, defaultRingtoneUri); // first add the default, to get back if select another
while (cursor.moveToNext()) {
String notificationTitle = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX);
Uri notificationUri = manager.getRingtoneUri(cursor.getPosition());
list.put(notificationTitle, notificationUri);
}
return list;
}
Then Create a dialog for select :
public static void getRingtonesDialog(Activity activity, Collection<String> items, int selected, DialogInterface.OnClickListener itemClickListener, DialogInterface.OnClickListener okClickListener, final DialogInterface.OnClickListener cancelClickListener) {
AlertDialog.Builder builderSingle = new AlertDialog.Builder(activity);
builderSingle.setTitle("Select Ringtone");
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<>(activity, android.R.layout.select_dialog_singlechoice);
arrayAdapter.addAll(items);
builderSingle.setNegativeButton(android.R.string.cancel, cancelClickListener);
builderSingle.setPositiveButton(android.R.string.ok, okClickListener);
builderSingle.setSingleChoiceItems(arrayAdapter, selected, itemClickListener);
builderSingle.setCancelable(false);
builderSingle.show();
}
Then Select And Play them to test : (Here AppSettings settings is SharedPreferences in your App ) :
Map<String, Uri> mRingtonesMap;
private Uri mLastSelectedRingtone = null;
private String mLastSelectedRingtoneName = "Default";
private MediaPlayer mMediaPlayer;
AppSettings settings;
TextView mRingtone ;
in Oncreate :
mRingtone = (TextView)findViewById(R.id.mRingtone);
settings = AppSettings.getInstance(this);
mRingtone.setText(getString(R.string.set_alarm_select_ringtone,
settings.getString(AppSettings.Key.SELECTED_RINGTONE_NAME, mLastSelectedRingtoneName)));
mRingtone.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
setupRingtoneSelection();
}
});
Then :
private void setupRingtoneSelection() {
mRingtonesMap = AlarmUtils.getRingtones(SelectionsActivity.this);
mRingtone.setText(getString(R.string.set_alarm_select_ringtone,
settings.getString(AppSettings.Key.SELECTED_RINGTONE_NAME, mLastSelectedRingtoneName)));
mRingtone.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final List<String> ringtoneKeys = new ArrayList<>(mRingtonesMap.keySet());
String ringtoneUri = settings.getString(AppSettings.Key.SELECTED_RINGTONE, "");
int selected = -1;
for (int i = 0; i < ringtoneKeys.size(); i++) {
String ring = ringtoneKeys.get(i);
if (mRingtonesMap.get(ring).toString().equalsIgnoreCase(ringtoneUri)) {
selected = i;
break;
}
}
AlarmUtils.getRingtonesDialog(SelectionsActivity.this, ringtoneKeys, selected, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) { //item selected
String name = ringtoneKeys.get(which);
mLastSelectedRingtoneName = name;
mLastSelectedRingtone = mRingtonesMap.get(name);
try {
if (mMediaPlayer == null) {
mMediaPlayer = new MediaPlayer();
} else {
mMediaPlayer.stop();
mMediaPlayer.reset();
}
mMediaPlayer.setDataSource(SelectionsActivity.this, mLastSelectedRingtone);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setLooping(false);
mMediaPlayer.prepare();
mMediaPlayer.start();
} catch (IOException ioe) {
//do nothing
}
}
}, new DialogInterface.OnClickListener() { //ok
#Override
public void onClick(DialogInterface dialog, int which) {
if (mMediaPlayer != null) {
mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
}
settings.set(AppSettings.Key.SELECTED_RINGTONE, mLastSelectedRingtone.toString());
settings.set(AppSettings.Key.SELECTED_RINGTONE_NAME, mLastSelectedRingtoneName);
//Update the textview
mRingtone.setText(getString(R.string.set_alarm_select_ringtone,
settings.getString(AppSettings.Key.SELECTED_RINGTONE_NAME, mLastSelectedRingtoneName)));
dialog.dismiss();
}
}, new DialogInterface.OnClickListener() { //cancel
#Override
public void onClick(DialogInterface dialog, int which) {
if (mMediaPlayer != null) {
mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
}
dialog.dismiss();
}
});
}
});
}
#Override
protected void onDestroy() {
if (mMediaPlayer != null) {
if (mMediaPlayer.isPlaying()) {
mMediaPlayer.stop();
}
mMediaPlayer.release();
mMediaPlayer = null;
}
mRingtone.setOnClickListener(null);

Android cannot bind to service (In App-Billing)

I'm trying to implement in app-billing in my application, but I have a little problem with it. I'm using the example from android developer's site and everytime I start the activity which will connect to the billing service it's showing me a dialog that I cannot connect to server and when I press learn more it's going to a web page which is explaining me to update my android market app, but it's already the latest one. And the other thing, before implementing the code on my application I create a test application where I can connect with the same code and I don't get problems. But in my application I can't do that. Is there any connection with the developer api key, which you can use only in one application or something like that. Because I'm using the same for test and real app.
And here is my code if you can see something which is not really like it should be :
public class StampiiStore extends Activity {
String servername;
int userId;
int storageID;

And here is how I'm declaring the service in manifest file :
<service android:name="BillingService" />
<receiver android:name="BillingReceiver">
<intent-filter>
<action android:name="com.android.vending.billing.IN_APP_NOTIFY" />
<action android:name="com.android.vending.billing.RESPONSE_CODE" />
<action android:name="com.android.vending.billing.PURCHASE_STATE_CHANGED" />
</intent-filter>
</receiver>
Any suggestions how to connect to the market?

I had the same issue and probably your mistake is the same as mine. I was using a TabHost in my activities and I find out that TabSpec cannot bind to services. So check this :
Using getApplicationContext().bindService instead of just bindService
on your activity solves the problem as it is using the higher level
application context.

Can't you debug through that code? Probably, mBillingService.checkBillingSupported() returns false, caused by failing BillingService.bindToMarketBillingService().

i was facing problem like that on my sony ericssion w8 2.1 android device
what i did are the following :
1) getApplicationContext().bindService (as android-droid said)
2) reset my mobile and downloaded apk for market 2.3.4 version and installed it
3) then open the market app on mobile and clicked accepted and when the app i quitted
4) rerunned the app it was working fine
note: before doing this i tested my app on other device using market version 3.x and it was working so i did all these things ...
