我正在开发一个React-Native应用程序，我们正在尝试使用两个视频聊天库（OpenTok和Skylink）。两者都使用org.webrtc（libjingle），在构建过程中我们遇到了一个问题：

在OpenTok build.gradle中，我们有：
apply plugin: 'com.android.library'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
minSdkVersion 16
targetSdkVersion 22
versionCode 1
versionName "1.0"
ndk {
abiFilters "armeabi-v7a", "x86"
}
}
}
dependencies {
compile 'com.facebook.react:react-native:+'
compile('com.opentok.android:opentok-android-sdk:2.10.+') {
exclude group: 'org.webrtc'
}
compile project(':react-native-permission-helper')
}
对于SkyLink build.gradle
apply plugin: 'com.android.library'
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'
}
}
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
minSdkVersion 16
targetSdkVersion 22
versionCode 1
versionName "1.0"
ndk {
abiFilters "armeabi-v7a", "x86"
}
}
}
dependencies {
compile fileTree(include: '*.jar', excludes: ['libjingle_peerconnection.jar', 'libjingle_peerconnection_java.jar'], dir: 'libs')
compile(group: 'sg.com.temasys.skylink.sdk', name: 'skylink_sdk', version: '0.9.7-RELEASE', ext: 'aar')
compile 'com.facebook.react:react-native:+'
compile project(':react-native-permission-helper')
}
但是这种配置仍然无效。在最后的构建步骤中，仍然包含两个“libjingle_peerconnection.jar”。我能帮忙解决这个问题吗？我们可以控制gradle构建脚本，但不能控制第三方SDK。
答案 0 :(得分：0)
我能够通过将以下任务添加到我的主build.gradle
来修复此问题（尽管是以一种黑客的方式）tasks.create("excludeTask") << {
File file = file("${buildDir}/intermediates/exploded-aar/com.opentok.android/opentok-android-sdk/2.10.1-REL-2756/jars/libs/libjingle_peerconnection_java.jar");
println("Excluding file " + file)
if (file.exists()) {
file.delete();
}
}
tasks.whenTaskAdded({
if (it.name.matches(/^process.*Resources$/)) {
it.dependsOn excludeTask
}
})
