エラーを報告することで、プレーヤーが使用しているV 4ライブラリと私たちが構成しているV 4ライブラリが衝突し、バージョンが衝突していることが推測されます.
 
ソリューション
ソリューションは、プロジェクトのsupport-v 4またはGSYVideoPlayerのsupport-v 4を削除して一意性を維持することにほかならない.
シナリオ1:プロジェクトのsupport-v 4を削除
欠点:プロジェクトが使用できない support-v 4下のAPI

compile('com.android.support:appcompat-v7:23.3.0') {
　　exclude group: "com.android.support", module: "support-v4"
}

シナリオ2:GSYVideoPlayerのsupport-v 4を削除
利点:プロジェクトの使用に影響しない support-v4
欠点:プロジェクトが複数のオープンソースフレームに関連している場合、この問題が発生した場合は、オープンソースフレームの下で個々に削除します.

implementation ('com.shuyu:GSYVideoPlayer:6.0.1') {
    exclude module: 'support-v4'
    exclude group: 'com.android.support'
}

一般的には、競合を解決するために2つ目の方法を選択します.これにより、より制御できます.
