java - 将 firebase 添加到应用程序时出现 appcompat 依赖项错误

Question

我开发了一个简单的应用程序，在按下按钮后显示设备的 IMEI 以及纬度和经度。现在，我想将此数据(纬度、经度、IMEI)保存在 FireStore 中，我有一些理解问题，我应该在哪里以及如何将这些数据保存到 firestore 中。当我尝试通过工具将实时 firebase 添加到我的应用程序时，我遇到了一些错误

我已尝试更改依赖项版本，但无法解决问题。

@Override

    client = LocationServices.getFusedLocationProviderClient(this);

    });

    } else {

        TelephonyManager mngr =

        IMEI = mngr.getDeviceId();

        imei.setText(mngr.getDeviceId());

    }
}

}

这些是错误

 And if i change to 17.0.0 version from 11.0.1 in 'com.google.android.gms:play-

Answer 1

This release is a MAJOR version update and breaking change.

The latest update to Google Play services and Firebase includes the following changes:

Migration from Android Support Libraries to Jetpack (AndroidX) Libraries. Libraries will not work unless you make the following changes in your app:

• Upgrade com.android.tools.build:gradle to v3.2.1 or later.
• Upgrade compileSdkVersion to 28 or later.
• Update your app to use Jetpack

(AndroidX); follow the instructions in Migrating to AndroidX.

Firebase Bill of Materials (BoM)

问题是最新的 firebase 和 play-services 依赖被迁移到了 androidx。所以一个修复是将您的项目迁移到 androidx，请参阅 migrate to androidx (我更喜欢，因为所有新升级都使用 androidx)。或者您可以将 firebase-core 和 play 服务降级到此更新之前的版本。
