在浏览器而非Facebook App上打开Facebook

Question

I'm trying to make facebook for "someone" else opens on application, not on a browser, for example National Geography https://www.facebook.com/natgeo

Here is the code I have:

ddc.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View arg0) {

      Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/natgeo"));
      startActivity(browserIntent);
    }
});

I found one on stackoverflow and I tried it and it has errors, here is the code:

try {
    //try to open page in facebook native app.
    String uri = "fb://page/" + natgeo;    //Custom URL
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
    startActivity(intent);   
}
catch (ActivityNotFoundException ex){
    //facebook native app isn't available, use browser.
    String uri = "https://www.facebook.com/natgeo" + natgeo;  //Normal URL  
    Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uriMobile));    
    startActivity(i); 
}

the thing is I want, if someone didn't have facebook App, it will open in the browser.

You use a variable, which is not declared before (read compiler errors)..

Add String natgeo = "my content"; before your try-catch block to make your code compiling.
