SendGrid for Android
问题
在将Gradle依赖项添加到我的Android项目后，当我尝试构建/运行项目时，我会收到以下错误消息：不支持的类文件主版本59。以下是我添加的应用级和项目级Gradle文件。我尝试了各种搜索，但未找到相关答案。我还在Github的SendGrid Issues中提出了相同的问题，但尚未收到任何回复。
// App-level Gradle中我添加了以下内容
apply plugin: 'com.android.application'
android {
compileSdkVersion 29
buildToolsVersion "29.0.3"
defaultConfig {
applicationId "com.app.hiforce"
minSdkVersion 21
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
debug {
applicationIdSuffix = '.dev'
debuggable = true
buildConfigField('String', 'BaseUrl', DevBaseUrl)
manifestPlaceholders = [appLabel: "DEV-HiForce"]
}
release {
minifyEnabled false
buildConfigField('String', 'BaseUrl', ReleaseUrl)
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}

}
apply plugin: 'com.google.gms.google-services'
// 应用Crashlytics Gradle插件

// 项目级Gradle中我添加了以下内容

After adding Gradle dependencies to my Android Project. So when I try to build/run my project I get this error Unsupported class file major version 59
Below I have added both the Gradle files App-level as well as the Project level. I tried searching all the over but couldn't find any related answer. I have also put the same in Github SendGrid Issues but didn't got any response yet.

集成Sendgrid的Java库到Android并不是一件直接的事情...
实际上，我已经使用Sendgrid的最新API为Android构建了一个Sendgrid库。
https://github.com/Jakebreen/android-sendgrid
implementation 'uk.co.jakebreen:android-sendgrid:1.2.3'
我在维护这个库，所以如果你有任何问题，请在GitHub页面上创建一个问题记录。
