我在android应用程序中有AB类。此类具有一个公共接口INF。
当我尝试使用启用了proguard的发布版本时，它说
错误：找不到符号类INF
在我的proguard.cfg文件中，添加了以下几行：
-keep public interface com.some.somemore.AB$INF {*;}
-keep class com.some.somemore.AB {*;}
请帮助为什么会出现此错误。
public class AB {
public interface INF {
public void Ready();
public void Error(int error);
public void Click();
public void Complete();
public void Dismiss();
}
}
这是崩溃日志

我在Studio项目中将这个开源项目https://github.com/nexage/sourcekit-vast-android用作模块。它在名为VAST的开源项目中崩溃。
我已在Studio项目中将VAST添加为模块依赖项。我已经为我的Studio项目以及VAST模块启用了proguard。
这是我用于VAST模块的proguard.config文件：
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontpreverify
-dontshrink
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-keep class org.nexage.sourcekit.vast.VASTPlayer {*;}
-keep interface org.nexage.sourcekit.vast.VASTPlayerListener {*;}
-keep class org.nexage.sourcekit.vast.model.** {*;}
-keep class org.nexage.sourcekit.vast.processor.** {*;}
-keep class org.nexage.sourcekit.vast.activity.** {*;}
-keep class org.nexage.sourcekit.util.** {*;}
最佳答案
您的实现应如下所示：
import com.my.packagename.AB;
public class MainActivity extends ActionBarActivity implements AB.TestInterface {
// other stuff
@Override
public void Ready() {
}
@Override
public void Error(int error) {
}
@Override
public void Click() {
}
@Override
public void Complete() {
}
@Override
public void Dismiss() {
}
}
您需要导入父类，希望对您有所帮助。
