Android端Facebook Graph API仅返回name和id，求助获取完整public_profile信息

Hey there! I’ve run into this exact issue before, so let’s break down what’s going on and how to fix it:

1. You’re Not Explicitly Requesting the Required Fields #

Starting with Graph API v2.4+, Facebook doesn’t return all public_profile fields by default—even if you’ve requested the right scopes. You need to explicitly specify which fields you want in your request.

For example, instead of just calling /me, append the fields parameter to define exactly what data you want:

GraphRequest request = GraphRequest.newMeRequest(
    AccessToken.getCurrentAccessToken(),
    new GraphRequest.GraphJSONObjectCallback() {
        @Override
        public void onCompleted(JSONObject object, GraphResponse response) {
            // Handle your response data here
        }
    });
Bundle parameters = new Bundle();
// List all fields you need from public_profile, email, and user_birthday
parameters.putString("fields", "id,name,email,birthday,gender,first_name,last_name,profile_picture");
request.setParameters(parameters);
request.executeAsync();

This tells Facebook to send back the specific fields you’ve listed, rather than just the default id and name.

2. Verify the User Actually Granted the Permissions #

Setting scopes in your login flow doesn’t guarantee the user accepted all of them—users can choose to deny certain permissions during authorization.

To check which permissions are currently granted, make a quick request to /me/permissions:

GraphRequest permissionCheckRequest = GraphRequest.newGraphPathRequest(
    AccessToken.getCurrentAccessToken(),
    "/me/permissions",
    new GraphRequest.GraphJSONObjectCallback() {
        @Override
        public void onCompleted(JSONObject object, GraphResponse response) {
            try {
                JSONArray permissions = object.getJSONArray("data");
                for (int i = 0; i < permissions.length(); i++) {
                    JSONObject perm = permissions.getJSONObject(i);
                    String permName = perm.getString("permission");
                    String status = perm.getString("status");
                    Log.d("FB Permissions", permName + ": " + status);
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    });
permissionCheckRequest.executeAsync();

If email or user_birthday show a status of declined, you’ll need to prompt the user to re-authorize those permissions.

3. Check if Permissions Need Facebook Review #

For non-test users, certain permissions like user_birthday require Facebook’s app review before they’re accessible in production. If you’re testing with a regular user (not added as a test user in your Facebook Developer Dashboard), you might only get default fields until the permission is approved.

Head to your Facebook App Dashboard, navigate to App Review > Permissions and Features, and check if user_birthday and email are marked as "Approved" or need to be submitted for review.

4. Ensure You’re Using a Compatible Facebook SDK Version #

Outdated versions of the Facebook Android SDK can cause unexpected behavior with permission handling or field requests. Make sure your module-level build.gradle has the latest SDK dependency:

dependencies {
    // Replace with the latest stable version (check Facebook's docs for updates)
    implementation 'com.facebook.android:facebook-android-sdk:17.0.0'
}

After updating, sync your Gradle project and test again.

Quick Debug Checklist #

1. Add the explicit fields parameter to your request (this is the most common fix).
2. Confirm the user granted all requested permissions via the /me/permissions endpoint.
3. Verify if your app needs permission review for non-test users.
4. Update your Facebook SDK to the latest compatible version.

Let me know if any of these steps get you the full data you need!
