+
+```java
+// Give the topmost view of your activity layout hierarchy. This will be used to measure soft keyboard height
+PopupWindow popup = new EmojiconsPopup(rootView, getActivity());
+
+//Will automatically set size according to the soft keyboard size        
+popup.setSizeForSoftKeyboard();
+
+//Set on emojicon click listener
+popup.setOnEmojiconClickedListener(new OnEmojiconClickedListener() {
+            
+            @Override
+            public void onEmojiconClicked(Emojicon emojicon) {
+                emojiconEditText.append(emojicon.getEmoji());
+            }
+        });
+
+//Set on backspace click listener
+popup.setOnEmojiconBackspaceClickedListener(new OnEmojiconBackspaceClickedListener() {
+    
+    @Override
+    public void onEmojiconBackspaceClicked(View v) {
+        KeyEvent event = new KeyEvent(
+                 0, 0, 0, KeyEvent.KEYCODE_DEL, 0, 0, 0, 0, KeyEvent.KEYCODE_ENDCALL);
+                 emojiconEditText.dispatchKeyEvent(event);
+    }
+});
+
+//Set listener for keyboard open/close
+popup.setOnSoftKeyboardOpenCloseListener(new OnSoftKeyboardOpenCloseListener() {
+            
+            @Override
+            public void onKeyboardOpen(int keyBoardHeight) {
+                if(!popup.isShowing()){
+                    popup.showAtBottom();
+                }
+            }
+            
+            @Override
+            public void onKeyboardClose() {
+                if(popup.isShowing())
+                    popup.dismiss();
+            }
+        });
+
+//To show popup manually you can call popup.showAtBottom();
+```
