因为android工作室不允许我使用低于26的sdk版本，我有一些使用animatorcompathelper的代码，还有一些使用com.android旧版本编写的其他用法。support:support-v4 现在我真的不知道该怎么解决我的问题。以下是我当前不起作用的依赖项：

dependencies {
        implementation 'com.android.support:multidex:1.0.3'
        implementation 'com.onesignal:OneSignal:3.15.3@aar'
        implementation 'com.android.support:support-v4:26.1.0'
        implementation 'com.android.support:appcompat-v7:26.1.0'
        implementation 'com.android.support:support-compat:26.1.0'
        implementation 'com.google.android.gms:play-services-gcm:15.0.0'
        implementation 'com.google.android.gms:play-services-maps:15.0.0'
        implementation 'net.hockeyapp.android:HockeySDK:3.6.2'
        implementation 'com.googlecode.mp4parser:isoparser:1.0.6'
        implementation 'com.android.support:design:26.1.0'
        implementation 'de.hdodenhof:circleimageview:2.1.0'

        implementation 'com.android.support:cardview-v7:26.1.0'
        implementation 'com.android.support:recyclerview-v7:26.1.0'

        implementation('com.crashlytics.sdk.android:crashlytics:2.6.3@aar') {
            transitive = true;
        }
        implementation files('libs/gson-2.2.2.jar')
        implementation files('libs/adPlayAndroidv2.5.jar')
        implementation project (':pushe-lib-1.3.1')
    }

android studio 3.5.3版
