问题
I'm using Facebook SDK in my Android App. And I need to get all the information of the user. By now I'm able to get the Name ID Email Birthday and the profile pic of the user. The last one that I need to get is the location or current location of the user. I'm using this code below.
if(fb.isSessionValid()){
button.setImageResource(R.drawable.logout_button);
JSONObject obj = null;
URL img = null;
try {
String jsonUser = fb.request("me");
obj = Util.parseJson(jsonUser);
String id = obj.optString("id");
String name = obj.optString("name");
String bday = obj.optString("birthday");
String address = obj.optString("location");
String email = obj.optString("email");
((TextView) findViewById(R.id.txt)).setText("Welcome! "+name);
((TextView) findViewById(R.id.txtbday)).setText("Birthday: "+bday);
((TextView) findViewById(R.id.txtaddress)).setText("Address: "+address);
((TextView) findViewById(R.id.txtemail)).setText("Email: "+email);
img = new URL("http://graph.facebook.com/"+id+"/picture?type=normal");
Bitmap bmp = BitmapFactory.decodeStream(img.openConnection().getInputStream());
pic.setImageBitmap(bmp);
} catch (FacebookError e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}else{
button.setImageResource(R.drawable.login_button);
}
}
Here are the permissions
fb.authorize(MainActivity.this,new String[] {"email", "user_location", "user_birthday","publish_stream"}, new DialogListener() {
public void onFacebookError(FacebookError e) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), ""+e, Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
public void onError(DialogError e) {
// TODO Auto-generated method stub
//Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_SHORT).show();
}
public void onComplete(Bundle values) {
// TODO Auto-generated method stub
Editor editor = sp.edit();
editor.putString("access_token", fb.getAccessToken());
editor.putLong("access_expires", fb.getAccessExpires());
editor.commit();
updateButtonImage();
}
public void onCancel() {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Cancel", Toast.LENGTH_SHORT).show();
}
});
}
Thanks for who will help in advanced.
回答1:
The Graph API Explorer tool is a great way to see what the response of a graph API endpoint is. Just request the right permissions (such as user_location) by clicking "Get Access Token" and see the output of '/me'. When I get an access token with the user_location permission I am able to see my current
https://developers.facebook.com/tools/explorer/?method=GET&path=me
To get the current location, this is how to do it:
String currentCity = obj.getJSONObject("location").getString("name");
With newer SDKs you can get location detail by passing as below with graph API object
graphObject.getInnerJSONObject().getJSONObject("location").getString("id"))
