我在尝试让Google Calendar Api与我合作时遇到了很多麻烦。我经常搜索并尝试了许多似乎失败的解决方案。
我尝试了什么： - 启用Contacts API - Google+ API - Google Calendar API - 在调试/发布模式下运行应用程序 - 多次重新创建SHA1代码 - 更改应用名称
这是我的MainActivity，它类似于快速入门中的那个，但我做了一些事情来改变它以创建一个事件。
package com.example.roudy.calendarplayground;
public class MainActivity extends AppCompatActivity implements EasyPermissions.PermissionCallbacks{
private GoogleAccountCredential mCredential;
private static final int REQUEST_ACCOUNT_PICKER = 1000;

private static final int REQUEST_GOOGLE_PLAY_SERVICES = 1002;
private static final int REQUEST_PERMISSION_GET_ACCOUNTS = 1003;

private static final String[] SCOPES = { CalendarScopes.CALENDAR };
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mCredential = GoogleAccountCredential.usingOAuth2(
getApplicationContext(), Arrays.asList(SCOPES))
.setBackOff(new ExponentialBackOff());
getResultsFromApi();

以下是我得到的错误。在询问这个问题之前，我已经确定一切都是应该的，我到处搜索答案，似乎没有任何效果。 ＆＃34;取消（真）＆＃34;当然是触发但是没有输入if条件，顺便说一下。 （见代码）

答案 0 :(得分：0)
由于错误可以报告项目＃，这意味着您已正确输入SHA-1和API密钥。它必须是Google Dev Console中的一个问题。
这是您需要做的事情：
登录＆gt;图书馆＆gt; Google Calendar API
在该屏幕上，您应该能够为所有API密钥启用此API。单击“启用”后，继续执行凭据页面。
创建凭据＆gt;帮我选择
进入后，请输入您正在使用的API以及使用它的位置。在您的情况下，它将是Google Calendar API和Android。输入后，开发者控制台应该帮助您创建0Auth 2.0凭据，以便Google用户可以登录并在您的应用中使用Google日历API。希望这有帮助！
