I\'m unlocking achievement using this simple method from developers docs:
Games.Achievements.unlock(getApiClient(), \"my_achievement_id\");
Had the same problem. I have solved it by adding icon to the achievement. I am not kidding, it is really strange but it started to work after that. Please note that I am talking about not published project, I was just testing my app and wondering what is going on.
<FrameLayout
android:id="@+id/gps_popup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp" />
This is the same in Jacek Kwiecień answer
GamesClient gamesClient = Games.getGamesClient(MainActivity.this, GoogleSignIn.getLastSignedInAccount(context));
gamesClient.setViewForPopups(findViewById(R.id.gps_popup));
This changed because setViewForPopups with 2 parameters is deprecated.
Jacek and user3782779 answers didn't work for me, I had to do the following:
GamesClient gamesClient = Games.getGamesClient(this, GoogleSignIn.getLastSignedInAccount(this));
gamesClient.setViewForPopups(findViewById(android.R.id.content));
gamesClient.setGravityForPopups(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
Just add a view to the layouts you want to display achievements on like this:
<FrameLayout
android:id="@+id/gps_popup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp" />
When you have your layout ready you neet to execute this inside your Activity or Fragment:
Games.setViewForPopups(getApiClient(), findViewById(R.id.gps_popup));
You have to be sure, that your GoogleApiClient is connected though, otherwise your app will crash.
