Activity cannot be cast to com.google.android.gms.common.api.GoogleApiClient$ConnectionCallbacks

I am calling checkLocationOn method from another class as 

 // Change Address Click Action
    tvProfileChangeAddress.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if (Build.VERSION.SDK_INT >= 23) {
                if ((checkSelfPermission(android.Manifest.permission.ACCESS_FINE_LOCATION)
                        == PackageManager.PERMISSION_GRANTED)) {
                    GetLocation.checkLocationOn(Profile.this);
                }else{
                    AskPermissions.AskLocationPermission(Profile.this);
                }
              } else {
                GetLocation.checkLocationOn(Profile.this);
            }
            }
        });

I have Initialized My GoogleApiClient in CheckLocation method.

 // Building Google API Client
protected static synchronized void buildGoogleApiClient(Context context){
    mGoogleApiClient = new GoogleApiClient.Builder(context)
            .addApi(LocationServices.API)
            .addConnectionCallbacks((GoogleApiClient.ConnectionCallbacks) context)
            .addOnConnectionFailedListener((GoogleApiClient.OnConnectionFailedListener) context)
            .build();
    mGoogleApiClient.connect();
    createLocationRequest();
    return;

}

while Initializing GoogleApiClient my Application force stops giving error

03-27 16:43:13.930 5118-5118/? E/AndroidRuntime: FATAL EXCEPTION: main Process: com.demo.FetchLocation, PID: 5118 java.lang.ClassCastException: com.demo.FetchLocation.Profile cannot be cast to com.google.android.gms.common.api.GoogleApiClient$ConnectionCallbacks at com.demo.FetchLocation.GetLocation.buildGoogleApiClient(GetLocation.java:75) at com.demo.FetchLocation.GetLocation.checkLocationOn(GetLocation.java:68) at com.demo.FetchLocation.Profile$2.onClick(Profile.java:128) at android.view.View.performClick(View.java:5269) at android.view.View$PerformClick.run(View.java:21556) at android.os.Handler.handleCallback(Handler.java:815) at android.os.Handler.dispatchMessage(Handler.java:104) at android.os.Looper.loop(Looper.java:207) at android.app.ActivityThread.main(ActivityThread.java:5769) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:789) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:679)

protected static synchronized void buildGoogleApiClient(Context context){
mGoogleApiClient = new GoogleApiClient.Builder(context)
        .addApi(LocationServices.API)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .build();
mGoogleApiClient.connect();
createLocationRequest();
return;

}

write this and implement all methods of the interfaces you are implementing in your acctivity.

Have your Profile activity implemented both GoogleApiClient.ConnectionCallbacks and GoogleApiClient.OnConnectionFailedListener interfaces.

When you're executing following,

.addConnectionCallbacks((GoogleApiClient.ConnectionCallbacks) context)
            .addOnConnectionFailedListener((GoogleApiClient.OnConnectionFailedListener) context)

you don't actually have implemented any of those Interfaces in your passed context, which in your case, belongs to Profile activity.

According to the official documentation, the right method call is:

if (mGoogleApiClient == null) {
    mGoogleApiClient = new GoogleApiClient.Builder(this)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .addApi(LocationServices.API)
        .build();
}
