Answer 1

现在的问题是，如果API密钥正确，我会得到一个空白屏幕，如果我故意导致错误的密钥，则会出现身份验证错误

如果您拥有正确的API密钥，可以尝试以下内容：

1. 启用Manifest上的权限。

       <uses-permission android:name="android.permission.INTERNET" />
       <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
       <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
       <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
       <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

2. 确保您在清单中提供了正确的软件包名称以及GDC中的SHA1证书指纹。
3. 将Google Maps API设置为已启用。

希望有所帮助。
