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:
logcat1
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());
}

You need to post the code from your doInBackground method as well. It is possible that your activity is somehow exited during that method, so trying to create an AlertDialog from "mContext" (whatever that is, show the rest of your code) causes a window leak.
This other question may have what you need: Activity has leaked window that was originally added
The problem is likely that you need to dismiss() your AlertDialog before changing/leaving activities, or you need to make sure the activity is active before you create it.

Finally found a solution, the problem was with the android:launchMode in the manifest.

simplymoody, do what Chirag Raval suggested by declaring private static TextView homeText1, globally and in your onCreate initialise them. However, you should always update the UI from the main thread. But showDisclaimer() is still running on the background thread, so you could run the showDisclaimer() a couple of different ways. One would be to do what you have done in getUploadDate():
runOnUiThread(new Runnable() {
public void run() {
showDisclaimer()
}
});
Or you could use a handler:
private Handler showDisclaimerHandler = new Handler(new Handler.Callback() {
#Override
public boolean handleMessage(Message msg) {
homeText3x.setText("TEXT");
homeText1x.setVisibility(View.VISIBLE);
homeText2x.setVisibility(View.VISIBLE);
homeText3x.setVisibility(View.VISIBLE);
homeText4x.setVisibility(View.VISIBLE);
Log.d("ShowDisclaimer", "finished showing disclaimer");
return false;
}
});
And everywhere in a background thread you wish to run your showDisclaimer(), instead you run:
showDisclaimerHandler.sendEmptyMessage(0);
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 :

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 ...
