我试图构建一个签名的 APK。我也在使用 proguard。在我的应用程序中,我出于某些目的使用了 JodaTime。我在那里使用了 joda-time-2.7.jar。首先,我可以在不启用 proguard 的情况下获得签名的 APK,没有任何错误。然后我启用了 proguard 并尝试生成 APK,但它生成了错误。以下是生成的错误。

You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.

下面是我的build.gradle文件:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.theacetechnologies.voicetype"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
compile files('libs/joda-time-2.7.jar')
}
知道为什么在启用 proguard 时我无法生成签名的 APK 吗?我相信这也与 Joda Time 有关,因为我之前在没有 JODA time 的情况下生成了启用混淆器的签名 APK。
最佳答案
将这些行添加到您的 proguard 文件中
-dontwarn org.joda.convert.**
-dontwarn org.joda.time.**
-keep class org.joda.time.** { *; }
-keep interface org.joda.time.** { *;}
关于java - 使用 Joda Time 时无法生成启用了混淆器的签名 APK,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/36421552/
