Question

我正在测试Admob的奖励视频，我收到的错误如下。代码是正确的，因为它适用于三星S7。

使用Jelly Bean 4.3.1在Samsung S3 mini上运行时出现错误。

首先我认为它可能是Exoplayer（1.3.1）的版本有点过时，但后来我尝试运行exoplayer演示，看起来我的设备没有正确的解码器：< / p>

我的build.gradle

compileSdkVersion 27
defaultConfig {
    applicationId "com.test.app"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode 1
    versionName "test reward videos"
}

所以我的问题是，如何添加丢失的解码器？

播放Admob奖励视频时，Exoplayer解码器初始化失败
