我正在尝试实现Playback Notifications with ExoPlayer。但是getTitle,getDescription,createPendingIntent(),getLargeIcon丢失,并且android studio显示为红色(无法解析方法)。我如何获得这些?
我编写的代码与链接完全相同。我尝试了多次。
这是我的build.gradle文件(如果需要):
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.mediaplayertest"
minSdkVersion 18
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation "com.android.support:support-media-compat:28.0.0"
implementation "com.android.support:support-compat:28.0.0"
implementation 'com.google.android.exoplayer:exoplayer:2.9.5'
}
答案 0 :(得分:0)
您需要正确定义gradle实现。
implementation 'com.google.android.exoplayer:exoplayer-core:2.X.X'
implementation 'com.google.android.exoplayer:exoplayer-dash:2.X.X'
implementation 'com.google.android.exoplayer:exoplayer-ui:2.X.X'
在gradle构建脚本中,您只需要“ exoplayer”
注意:对于PlaybackNotificationManager类,您将需要 exoplayer-ui ,这意味着您只需要该特定类
implementation 'com.google.android.exoplayer:exoplayer-ui:2.9.5'
,但我还会加入 exoplayer-core
