    WebView mWebView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ((TextView)findViewById(R.id.home)).setOnClickListener(new OnClickListener(){
            public void onClick(View v) {
                finish();

             super.onPageFinished(mWebView, url);

            Toast.makeText(getApplicationContext(), "Done!", Toast.LENGTH_SHORT).show();
        }  
    });
    mWebView.loadUrl("http://pabebbe.com/m/register");

    mWebView.setWebViewClient(new WebViewClient() {
       public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
         Toast.makeText(getApplicationContext(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
       }
       });
    }
}

The second call to setWebViewClient() is overwriting the first.

Create only a single instance of WebViewClient with both overrides in the same class, and call setWebViewClient only once. Then load the Webview:

mWebView.setWebViewClient(new WebViewClient() {
    @Override  
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(mWebView, url);
        Toast.makeText(getApplicationContext(), "Done!", Toast.LENGTH_SHORT).show();
    }  

    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        Toast.makeText(getApplicationContext(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
    }
});
mWebView.loadUrl("http://pabebbe.com/m/register");
