Android Can'；编辑SharedReferences时，不要在未调用Looper.prepare（）的线程内创建处理程序

我正在尝试学习和开发一个使用FCM的NoSQL数据库的示例应用程序。我已经在Firebase控制台上成功注册了我的应用程序，并且还通过该应用程序向数据库写入了一些虚拟值，这表明从我的应用程序到FCM服务器的连接已清除。现在，出于某种原因，我想使用SharedReference。当我尝试在onCreate方法中编辑键值对时，会出现以下错误：

Can't create handler inside thread that has not called Looper.prepare()

网址为： 在com.example.ankitshubham.ribbon.MyFireBaseInstancedService.onTokenRefresh（MyFireBaseInstancedService.java:18）上`

这是主要的活动：

public class MainActivity extends AppCompatActivity {
    private DatabaseReference mDatabase;
    private final int MY_PERMISSIONS_REQUEST_READ_GET_ACCOUNTS  =10;
    SharedPreferences sharedPreferences;
    private final static  String INIT_DB = "init_db";


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        FirebaseDatabase.getInstance().setPersistenceEnabled(true);
        mDatabase = FirebaseDatabase.getInstance().getReference();
        sharedPreferences = getSharedPreferences(INIT_DB, MODE_PRIVATE);
        if (!sharedPreferences.contains("firstrun")) {
            Toast.makeText(getApplicationContext(),"first run",Toast.LENGTH_SHORT).show();
            sharedPreferences.edit().putBoolean("firstrun", false).commit();
        }
        else {
            Toast.makeText(getApplicationContext(),"not the first run",Toast.LENGTH_SHORT).show();
        }
    }
}

这是MyFireBaseInstancedService：

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
    @Override
    public void onTokenRefresh() {
        super.onTokenRefresh();
        Log.i("Updated token", FirebaseInstanceId.getInstance().getToken());
        Toast.makeText(getApplicationContext(), FirebaseInstanceId.getInstance().getToken(),Toast.LENGTH_SHORT).show();

    }
}

如果我从MainActivity.java中删除以下行：

sharedPreferences.edit().putBoolean("firstrun", false).commit();

那么它不会显示任何错误。这里有什么问题
