my logcat file:

e/androidruntime: fatal exception: main process: com.ideabiz.fusedlocationprovider, pid: 18114 java.lang.classcastexception: com.ideabiz.fusedlocationprovider.mainactivity cannot cast com.google.android.gms.location.locationlistener @ com.ideabiz.fusedlocationprovider.mainactivity.onconnected(mainactivity.java:52) 

my manifest.xml file:

if take on logcat, error stated have imported wrong locationlistener. check on imported library @ top part of class, supposed com.google.android.gms.location.locationlistener not android.location.locationlistener.
