Android StudioからAPI 26を削除するにはどうすればよいですか？

Question

Androidスタジオは、26.0.0のコアサポートライブラリ、つまりアニメーションベクター描画可能ファイル、サポートアノテーション、サポート互換、サポートコアUIなどを使用するようにした更新を行いました。私のプロジェクトでは、 API 25を使用するように設定できます。依存関係の参照はすべて25.3.1で、buildToolsは25.0.3に設定されています。 targetSDKVersionも25です。私はファイル/設定&ファイル/プロジェクト構造のすべてをチェックしましたが、私はAPI26への参照を見つけることができませんが、スタジオはこれらの項目を含めてエラーをグラデルファイルに表示し、 API26で利用可能です。

この特定のプロジェクトでAndroid StudioでAPI 25を使用するにはどうすればよいですか？

NDK is missing a "platforms" directory. 
If you are using NDK, verify the ndk.dir is set to a valid NDK directory. It is currently set to C:\Android\sdk\ndk-bundle. 
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning. 

Incremental java compilation is an incubating feature.

Answer 1

あなたgradlew.bat dependencies出力：

\--- com.uservoice:uservoice-android-sdk:1.2.+ -> 1.2.6 
+--- com.android.support:support-core-utils:26.0.0 (*) 
+--- com.android.support:appcompat-v7:26.0.0 (*) 

はcom.uservoice:uservoice-android-sdk:1.2.6は、サポートライブラリのバージョン26.0.0に依存していることを示しています。 API25でコンパイルを続行する場合は、旧バージョンのライブラリを使用する必要があります（をGradle依存関係に使用することは、ほとんどの場合、これと他の多くの理由で、悪い考えです）

もちろん、Picking your compileSdkVersion blog postあたりとして：

があなたのcompileSdkVersionを変更すると実行時の動作を変更しないことを強調すべきです。 compileSdkVersionを変更すると、新しいコンパイラ警告/エラーが表示されることがありますが、compileSdkVersionはAPKには含まれていません。コンパイル時に純粋に使用されます。

したがって、は、常に最新のSDKでコンパイルすることを強くお勧めします（これらの警告は実際には修正する必要があります）。既存のコードに対する新しいコンパイルチェックの利点をすべて得て、新たに廃止予定のAPIを避け、新しいAPIを使用できるようにします。

最新のSDKの使用を検討する必要があります。
