HLS Exoplayer流无法在API级别28上运行

Question

HLS Stream无法在运行Android 9.0的设备和模拟器中播放。 HLS Stream适用于在API级别28以下运行的其他设备和模拟器。该应用程序正在使用Exoplayer v2库。

堆栈跟踪中的错误如下：

E/ExoPlayerImplInternal: Source error.
    com.google.android.exoplayer2.upstream.HttpDataSource$HttpDataSourceException: Unable to connect to http://streamIP/hls/stream.m3u8

        at java.lang.Thread.run(Thread.java:764)

目前的app/build.gradle如下：

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"
    defaultConfig {
        applicationId "com.example.app"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 14
        versionName "14.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }...
}

dependencies {
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:design:28.0.0'
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:appcompat-v7:28.0.0'
    testCompile 'junit:junit:4.12'

    implementation 'com.google.android.exoplayer:exoplayer:r2.5.2'
    implementation 'com.nineoldandroids:library:2.4.0'

    implementation 'com.android.support:multidex:1.0.3'
}

确保为Android 9允许不安全的网络连接。默认情况下禁用此功能。
