Answer 1

It looks like you misspelled the function name in your xml for the Button onClick(). You have an uppercase "m" in your java code

 public void sendMessage(View view) {

and probably a lowercase "m" in your xml

To comply with java standards, change it in your xml to

 android:onClick="sendMessage"/>
