As your error message says:
com.google.firebase.udacity.friendlychat.FriendlyMessage is missing a constructor with no arguments
So you must be missing a default constructor (constructor with no arguments) in your FriendlyMessage class

android getting null pointer exception at java.util.Objects.requireNonNull(Objects.java:203)

I'm reading writing string arrays and displaying them in recycler view.
Before displaying them i'm reversing the order using

Firebase ArrayList issues (need to use GenericTypeIndicator?)

Connecting to my Firebase database works fine when I install my app to my phone via USB. But when I install it via the Play Store, I get issues from Firebase about my ArrayList having "generic type parameters". Check out the first line of the logcat error message below:
09-14 15:59:55.715 4843-4843/? E/UncaughtException: com.google.firebase.database.f: Class java.util.ArrayList has generic type parameters, please use GenericTypeIndicator instead

Any thoughts? The Google Play version was working fine the other day and now this happened! Couldn't find any solutions online...
UPDATE:
I added the following code to my proguard-rules.pro file:
-keepattributes Signature
-keepclassmembers class com.test.finalapp.Models.** {
*;
}
-keep class com.test.finalapp.CoOpStatusHolder { *; }
Things are working fine in database, but now I'm hit with the error: java.lang.RuntimeException: java.lang.NoSuchMethodException: [class android.view.View]
That error is at the top of the larger logcat error:

CoOpStatusHolder is my FirebaseUI RecyclerView Viewholder. I made the Viewholder an inner class. I made it public static and it's in proguard-rules.pro file, so I'm still not sure what the issue is...
public static class CoOpStatusHolder extends RecyclerView.ViewHolder {
View mView;
public CoOpStatusHolder(View itemView) {
super(itemView);
mView = itemView;
}
public void setName(String name) {
TextView nameOfParentToChoose = (TextView) mView.findViewById(R.id.
textView_of_parent_name_in_co_op_status);
nameOfParentToChoose.setText(name);
}
public void setFacebookImage(String facebookID) {
ProfilePictureView parentFacebookPhoto = (ProfilePictureView) mView.findViewById(R.id.
imageview_of_parent_in_co_op_status);
parentFacebookPhoto.setProfileId(facebookID);
}
public void setHours(Float numofHours) {
TextView numOfHoursForParent = (TextView) mView.findViewById(R.id.
textView_num_of_hours_in_co_op_other_parent_status);
numOfHoursForParent.setText(Float.toString(numofHours));
}
}

Android Firebase Database Exception while runTransaction

I did search for this exception during runTransaction, but couldn't find any. Below is the code snippet where I get this exception:
dataSnapshot.getRef().runTransaction(new Transaction.Handler() {
#Override
public Transaction.Result doTransaction(MutableData mutableData) {
mutableData.child(order.getId() + "").setValue(order);
return Transaction.success(mutableData);
}

#Override
public void onComplete(DatabaseError databaseError, boolean isComplete, DataSnapshot dataSnapshot) {
logger.debug("isComplete - " + isComplete);
if(isComplete){
logger.debug("dataSnapshot - " + dataSnapshot);
callback.onSuccess(IConstants.USER_ORDER_SAVED);
} else {
logger.debug("databaseError - " + databaseError);
callback.onSuccess(IConstants.USER_ORDER_SAVE_FAILED);
}
}

});
I get this only with runTransaction. But setValue for a child and updateChildren are working good. Someone else faced with this scenario?
UPDATE:
The root cause i found is that, the Order POJO I was using has a sub-class which was not declared as static. I changed that, and everything is working as expected.

The appearance of dataSnapshot.getRef() in the code you posted is a clue that the code is running inside a listener callback. Let's say the listener is on location X. When you call dataSnapshot.getRef().runTransaction(), you are requesting the transaction on the value at location X. That value is the MutableData you get in the doTransaction() callback. In the doTransaction() callback, you are setting the value of a child of X, which is also a change to X itself. This causes the listener to fire again. I suspect that is the loop that is causing the stack overflow.
Also, this answer provides the details of how transactions are performed. It might be helpful.

For further readers... I had the problem that I had a method inside of my
POJO called getDBReference(), which was not static and returned the
DatabaseReference
to this POJO instance. Which, then in a transaction was falsely detected by reflection to "add" to the transaction and caused a StackOverFlow.
tl;dr
I forgot to annotate this method with #Exclude, that was the problem.

This occurs if u call FirebaseDatabase.getInstance() at several place . You should create a singleton instance of it and then use it throught out your project .
Example :
public class FirebaseUtils{
private static FirebaseDatabase mDatabase;
public static FirebaseDatabase getDatabase() {
if (mDatabase == null) {
mDatabase = FirebaseDatabase.getInstance();
}
return mDatabase;
} }
and get the database FirebaseUtils.getDatabase();

FirebaseAnalytics logEvent() causes OOM

I'm tracking how the user is navigating inside my application with Firebase like so:
43. FirebaseAnalytics mTracker = MyApplication.getDefaultTracker();
44. Bundle payload = new Bundle();
45. payload.putString(FirebaseAnalytics.Param.VALUE, "page");
46. mTracker.logEvent("Navigation", payload);
And once in a while I get OOM Exception with this stack trace:

How could I solve the problem below? I searched a lot but I didn't figure out.
I am using a fragment instead of an activity to call PaymentActivity.
Thanks in advance.
There is a piece of code below.
public void executarPagtoPayPal()
{
SearchResultsAdapter searchResultsAdapter = new SearchResultsAdapter(getActivity(), new ArrayList<Produto>());
PayPalPayment coisasAComprar = searchResultsAdapter.prepararCarrinhoFinal();
Intent i = new Intent(getActivity(), PaymentActivity.class);
i.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, payPalConfiguration);
i.putExtra(PaymentActivity.EXTRA_PAYMENT, coisasAComprar);
startActivityForResult(i,CODIGO_PAGTO);
}
