将电报 api jar 文件作为依赖项添加到 android prject 时，我收到调用动态不支持的错误

Question

我正在尝试以 android 应用程序的形式创建一个电报机器人，目标是：当我启动应用程序时，机器人将响应互联网上的用户！

但是当我将 Telegrambots-3.4-jar-with-dependencies.jar 添加到应用程序依赖项时，构建会出现以下警告和错误：

Information:Gradle tasks [:app:assembleDebug]
Warning:Ignoring InnerClasses attribute for an anonymous inner class
Error:com.android.builder.dexing.DexArchiveBuilderException: Failed to process C:Usersuser1DocumentsAndroidPjappBotapplibstelegrambots-3.4-jar-with-dependencies.jar

提到的jar文件，是电报机器人API！

这是我的build.gradle [模块：应用程序]

apply plugin: 'com.android.application'
android {
compileSdkVersion 26
defaultConfig {
applicationId "oa.azadi.omidazadibot"
minSdkVersion 15
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
implementation files('libs/telegrambots-3.4-jar-with-dependencies.jar')
}

Answer 1

尝试通过 gradle 依赖项添加依赖项。

在你的build.gradle中添加以下行。

dependencies {
compile 'com.github.pengrad:java-telegram-bot-api:3.5.2'
}

Answer 2

看起来，您忘记将 jar 添加到项目依赖项中。

右键单击您刚刚添加的jar文件，然后单击"添加为库"。这将负责在build.gradle文件中添加编译文件('libs/library_name.jar')。
