Can't get location and email using Facebook API

Question

In my Android application I developed this code to login with my account and get user property like name, location and email. The problem is I can get the name, but I can't get the email and the location. When I tried my code without try catch the application crush and my log point in getproperty("email") and getlocation(). When I use the try. The application work but there is no email or location.

public class Share extends Fragment {private static final String TAG ="Share";private UiLifecycleHelper uiHelper;

Answer 1

The issue is that you have not asked for permissions:

authButton.setReadPermissions(Arrays.asList("user_likes", "user_status","email","user_birthday"));

However, you are using an older Facebook SDK, while the newest SDK is 4.0.+. Below, I will give you a full sample code for Facebook login, based on the newest API. Keep in mind that you first have to add your application in developers.facebook as the documentation mentions out.

public class LoginActivity extends ActionBarActivity{

@Override
protected void onActivityResult(int requestCode, int responseCode, Intent data)
{
    super.onActivityResult(requestCode, responseCode, data);
    callbackManager.onActivityResult(requestCode, responseCode, data);
}

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(this.getApplicationContext());
    setContentView(R.layout.activity_login);
    callbackManager = CallbackManager.Factory.create();
    loginButton = (LoginButton) findViewById(R.id.loginFaceBook_button);
    List<String> permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile");
    loginButton.setReadPermissions(permissionNeeds);

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>()
    {
        @Override
        public void onSuccess(LoginResult loginResult)
        {
            System.out.println("onSuccess");
            GraphRequest request = GraphRequest.newMeRequest
                    (loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback()
                    {
                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response)
                        {
                            // Application code
                            Log.v("LoginActivity", response.toString());
                            //System.out.println("Check: " + response.toString());
                            try
                            {
                                String id = object.getString("id");
                                String name = object.getString("name");
                                String email = object.getString("email");
                                String gender = object.getString("gender");
                                String birthday = object.getString("birthday");
                                System.out.println(id + ", " + name + ", " + email + ", " + gender + ", " + birthday);
                            }
                            catch (JSONException e)
                            {
                                e.printStackTrace();
                            }

                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender, birthday");
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel()
        {
            System.out.println("onCancel");
        }

        @Override
        public void onError(FacebookException exception)
        {
            System.out.println("onError");
            Log.v("LoginActivity", exception.getCause().toString());
        }
    });
  }
}

If you want to use Fragment instead of ActionBarActivity, the just add loginButton.setFragment(this); right after your permission line.

manifest.xml:

<uses-permission android:name="android.permission.INTERNET"/> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<application
    <!-- your other attrs..-->
    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/app_id"/> <!-- Get this one from developers.facebook -->
    <activity
        android:name="com.facebook.FacebookActivity"
        android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:theme="@android:style/Theme.Translucent.NoTitleBar"
        android:label="@string/app_name"/>

You will need to add to your application a hash key too. Here is a way to do this with code:

try
{
    //paste Your package name at the first parameter
    PackageInfo info = getPackageManager().getPackageInfo("PUT_YOUR_PACKAGE_NAME_HERE",
            PackageManager.GET_SIGNATURES);
    for (android.content.pm.Signature signature : info.signatures)
    {
        MessageDigest md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String sign = Base64.encodeToString(md.digest(), Base64.DEFAULT);
        Log.e("MY KEY HASH:", sign);
        Toast.makeText(getApplicationContext(),sign,     Toast.LENGTH_LONG).show();
    }
}
catch (PackageManager.NameNotFoundException e)
{
}
catch (NoSuchAlgorithmException e)
{
}

After it prints you out the hash key, you copy paste it to your facebook.developer account, where your project is located.

In grandle, you should add jcenter in repositories and also add compile 'com.facebook.android:facebook-android-sdk:4.0.0' in dependecies.

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.1.0'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}
allprojects 
{
repositories {
    jcenter()
    /*more project attrs..*/
  }
}

And the other grandle file:

apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "YOUR_PACKAGE_NAME"
    minSdkVersion 14
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.facebook.android:facebook-android-sdk:4.0.0'
}

Edit:

In order to track the user's location, you will need a GPS Tracker, something like this. "user_location" permission does not return a lon, lat, but a Page object, which I think is not what you want. So, your permissions should be List<String> permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile"); and now you should be able to retrieve user's email
