在Android Studio

Question

我是改造的新手，我在我的项目中使用了改造，这对于我所需的所有设备版本来说都很好。但是在我的项目中添加了一个库模块之后，它只能在更高的版本上运行，比如22 v，并提示错误：

    Could not find class 'retrofit.Utils$SynchronousExecutor', referenced          
    from method retrofit.RestAdapter$Builder.setExecutors

    java.lang.NoClassDefFoundError: retrofit.RestAdapter$LogLevel

在14 v。

等较低版本上

我的app gradle是：

 apply plugin: 'com.android.application'

 android {
compileSdkVersion 23
buildToolsVersion '23.0.2'

defaultConfig {
    applicationId "com.risingkashmir"
    minSdkVersion 14
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
    multiDexEnabled true

}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
 }

 dependencies {
//   compile fileTree(dir: 'libs', include: ['*.jar'])
