我正在使用
com.amazon.android：exoplayer-ui：r2.5.4
在我的项目中，我只是将IDE升级到Android Studio 3.3.1。 在我的build.gradle中，我有以下编译的代码
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
在尝试构建时，我会收到此错误：
任务：app：mergeextdexdebug失败的agpbi： {" ank"：" error"，" text"："仅支持默认接口方法 从Android N（ - Min-API 24）开始：空隙 com.google.android.exoplayer2.player $ eventListener.onloadingChanged（boolean）"，" sources"：[{}]，"工具"：" D8"}
失败：构建失败而异常。
- 出了什么问题：无法解析配置的所有文件'：app：debugruntimeclasspath'。 无法将文件" class.jar"转换为匹配属性{artifactType = android-dex，dexing-is-debuggable = true， 使用transform dexingtransform dexing-min-sdk = 21} 触点时错误。
当我将sourceCompatibility和targetCompatibility更改为JavaVersion.VERSION_1_8时，它将成功构建，但是应用程序崩溃了以下错误：
e/androidruntime：致命例外：主要 过程：com.mypackage，pid：4374 java.lang.nosuchmethoderror：无直接方法（lcom/google/google/android/exoplayer2/upstream/defaultallocator; iijjlcom/google/google/android/exoplayer/exoplayer2/utitial/prioritytaskmanager;）v 在类lcom/google/android/exoplayer2/defaultloadControl中；或它的 超级课（声明 'com.google.android.exoplayer2.defaultloadControl'出现在 /data/app/mypackagename/base.apk：classes5.dex）
有什么建议？

应用程序级别 build.gradle

将您的SDK和关联的LIB升级到28 ...还将您的gradle升级到gradle-4.10.1-all.zip ...然后是rebuild应用程序...然后从File菜单中 Invalidate Cache/Restart。
如果仍无法工作，请添加以下代码，并按照rebuild和Invalidate Cache/Restart
