Android Geek :
Try this\n\nDatabaseReference mUsersDatabase;\n//for getting groups data\nmGroupsDatabase=FirebaseDatabase.getInstance().getReference().child(\"groups\");\n\n//add listener for getting uid or key\nmUserDatabase.addValueEventListener(new ValueEventListener() {\n @Override\n public void onDataChange(@NonNull DataSnapshot dataSnapshot) {\n if (dataSnapshot.exists()) \n {\n dataSnapshot.getKey();\n }\n }\n\n @Override\n public void onCancelled(@NonNull DatabaseError databaseError) {\n\n }\n });\n\n\nFor getting current user uid\n\nprivate FirebaseAuth mAuth;\nString mCurrentUserId;\n\nmAuth = FirebaseAuth.getInstance();\nmCurrentUserId = mAuth.getCurrentUser().getUid();\n\n\nHope it works for you!!",
