compileSdkVersion 29 と buildToolsVersion "29.0.0"で作成したプロジェクトをAPI 21でも動作する様に設定しエミュレータデバイスをRUNするとデバイス、プロジェクトは共に動くのですが上記のエラーがLog catに表示されました(プロジェクトのlayoutはconstraintをちゃんと設定しているのに位置やフォントが何故か部分的に崩れている。)。自身でエラーへの対応を調べbuildGradle(Module: app)のdependenciesにGoogle play servicesを追加・syncしてmanifest fileに

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

を追加したのですが以下のエラーが出現してデバイスも起動しなくなりました。どうすればエラーを解消出来るか考えあぐねているのですがアドバイスを頂けないでしょうか？

ちなみにGoogle play servicesを消して以前の状態にsyncしなおすと一番上のエラーに立ち戻ります。

Answer 1

おそらく、Firebaseが依存しているGoogle Playサービスのバージョンと、プロジェクトで追加したGoogle Playサービスのバージョンとで衝突が起きています。

app/build.gradle内の、

implementation 'com.google.android.gms:play-services:12.0.1'

という宣言は不要なはずなので削除して試してみてください。
