Question

我想删除我的FireBaseInstance

deleteInstanceId()是一个阻止电话.它不能在主线程上调用.如果您只需要调用它进行开发和测试,您可以使用一个简单的Thread:

            new Thread(new Runnable() {
                @Override
                public void run() {
                    try {
                        FirebaseInstanceId.getInstance().deleteInstanceId();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            }).start();
