Question
Hi i'm trying to add a FirebaseRecyclerAdapter to my app so users can scroll through their news feed and see recent posts. The images and information is stored in Firebase then is retrived from the user but the app keeps crashing with no error in the logcat and also date, time and description is not displayed in Firebase database using the hashmap, could that be the cause of the problem?
Please help .
post class:
public class post {
public String Uid,time,date,postimage,fullname,description,profileimage;
public post(){
}
public post(String uid, String time, String date, String postimage, String fullname, String description, String profileimage) {
Uid = uid;
this.time = time;
this.date = date;
this.postimage = postimage;
this.fullname = fullname;
this.description = description;
this.profileimage = profileimage;
}
public String getUid() {
return Uid;
}
public void setUid(String uid) {
Uid = uid;
}
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public String getPostimage() {
return postimage;
}
public void setPostimage(String postimage) {
this.postimage = postimage;
}
public String getFullname() {
return fullname;
}
public void setFullname(String fullname) {
this.fullname = fullname;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;

I think this problem happens for vector drawable. Use vector drawable true in your app level gradle file.
build.gradle(Module: app)
android {
defaultConfig{
vectorDrawables.useSupportLibrary = true
}
}

You are getting the following error:
"com.google.firebase.database.DatabaseException: Found two getters or fields with conflicting case sensitivity for property: uid"
Because in your post.class you have the Uid property which is starting with a capital letter. The way you can solve this is mentioned in my answer from this post .
