android - 在Android Studio中使用OneSignal获取Gradle错误

Question

我正在尝试将OneSignal合并到我的Android项目中。出现以下gradle错误，提示支持库必须具有相同版本。

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.google.android.gms:play-services-ads:10.2.4'
compile 'com.onesignal:OneSignal:[3.5.3,4.0.0)'
testCompile 'junit:junit:4.12'

}

Gradle提供了关于 的错误编译com.android.support:appcompat-v7:25.3.1'和 编译的com.google.android.gms:play-services-ads:10.2.4'。

Answer 1

您必须在Android list 中提供onesignal_app_id和onesignal_google_project_number值。

Attribute meta-data#onesignal_app_id@value at AndroidManifest.xml requires a placeholder substitution but no value for <onesignal_app_id> is provided.

Attribute meta-data#onesignal_google_project_number@value at AndroidManifest.xml requires a placeholder substitution but no value for <onesignal_google_project_number> is provided.

这些是构建失败的实际原因。不是您提到的库/依赖项
