注入的视图空值与机器人 3 当缩小启用 = true 时

Question

我在我的应用程序中使用了RoboGuice 3，当minifiedEnabled在调试模式下设置为false时，一切正常。但是，如果我将 minifiedEnabled 设置为 true，则注入的视图似乎为空：

NullPointerException: Attempt to invoke virtual method 'void android.support.v4.view.ViewPager.setAdapter(android.support.v4.view.PagerAdapter)' on a null object reference 

我的 ProGuard 配置如下所示：

-dontobfuscate
-dontoptimize
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontpreverify
-verbose

Answer 1

我可以通过将它添加到我的 proguard conf 中来修复它：

-keepclassmembers class * {
    ...
    @com.google.inject.InjectResource <init>(...);
    @com.google.inject.Inject <fields>;
    @com.google.inject.InjectView <fields>;
}

Answer 2

我通过将其添加到我的proguard中来修复它.txt，希望可以为您提供帮助

-keepclassmembers class * {
@roboguice.inject.InjectView <fields>;

}
