Class 在 android phone 上部署应用程序时找不到 java.time.LocalDateTime
Class not found for java.time.LocalDateTime while deploying app on android phone
我在 android phone.
上部署 android 应用程序时遇到 ClassNotFoundException
我试过 android phone 有 Android 6.0.1 和 Android 7.1.1
而当我在模拟器上部署相同的应用程序（Nexus 5X API 26）并运行 Android 8.0 时，我没有遇到任何问题。应用程序加载顺利。
Build.gradle (app) 文件有
android {
compileSdkVersion 28
defaultConfig {
applicationId "de.pfiva.mobile.voiceassistant"
minSdkVersion 23
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
我已经包含了来自本地 maven 的依赖项。这种依赖基本上有普通的 java 类 (POJO)。在某些 类 中有 java.time.LocalDateTime
类型的字段
我该如何解决这个问题。寻找建议。
谢谢。
