请建议如何解决上述问题。谢谢。看起来ProGuard可能正在剥离构建所依赖的类。尝试在禁用ProGuard（minifyEnabled false）的情况下进行发布构建，看看是否有效。如果这样做有效，那么您需要配置ProGuard规则，使其不会删除代码所依赖的类型。尝试向gradle添加PackageOptions，尝试清理项目，删除build文件夹，然后再次重建，指定gradle中使用的所有jar文件
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.package"
minSdkVersion 15
targetSdkVersion 23
versionCode 6
versionName "2.0.1"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

packagingOptions {

我通过在proguard规则文件的顶部添加
-ignorewarnings
