android - TestFairy 构建 apk 后初始化 fragment 上的 VerifyError

Question

这是一个奇怪的崩溃，任何人都可以解释它为什么会出现。

尝试在 ViewPager 中打开(通过标签或滑动)第三个 fragment 时出现崩溃(前两个此时自动初始化)Log中信息不多，直接提示'Verify'。

Android Studio创建的apk不能复现，只存在于TestFairy创建的apk中

已通过 break onServiceResult() 方法对两个方法进行修复。

在 TestFairy 日志中的警告中发现 W/dalvikvm？ VFY: 拒绝 Lmy.package/MyClass;.methodV

Answer 1

这个错误的原因需要在应用程序logcat中dalwik的警告中找到例如:带 dalvikvm？ VFY: 拒绝 Lmy.package/MyClass;.methodV

在这种情况下需要重构方法，因为你的方法太复杂了。在以下位置查看更详细的答案: VerifyError - Verifier rejected class
