我已在gradle文件中添加了依赖项，但仍无法识别jar文件的类 .
android {
compileSdkVersion 19
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.devstring.imageframe"
minSdkVersion 14
targetSdkVersion 14
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:18.0.0'
// compile files('D:/EKCS-data/EDCloud/e.d.cloud/libs/activation.jar')
// compile files('D:/EKCS-data/EDCloud/e.d.cloud/libs/activation.jar/additionnal.jar')
// compile files('D:/EKCS-data/EDCloud/e.d.cloud/libs/activation.jar/mail.jar')
compile fileTree(dir: 'libs', include: '*.jar')
}

[]，这是我用它的方式：如果这不起作用，您可以尝试使用maven central中的那些：
