java - Android Studio 0.5.4 更新导致 Java.Lang.VerifyError

Question

将我安装的 android studio 从 0.5.3 更新到 0.5.4 后，项目会在启动时抛出此错误。

我已经通过 SDK 管理器更新了 SDK，以获得 0.5.4 所需的新 Android SDK 工具。

我还更新了 gradle.build 中的构建工具以使用新更新的版本。

我已经删除了androidpreview文件夹，重启android studio也没有用。

我还验证了我的系统上只有 1 个 SDK，并且它的路径在 Android studio 中是正确的。

非常感谢任何建议。

这是 Logcat 输出...

Answer 1

java.lang.VerifyError 是在您针对与您在运行时使用的库不同的库进行编译时引起的。在运行时，当方法的签名不匹配时会抛出错误。或者当存在编译器错误时(尽管这种情况很少见)。

检查这一行:

Could not find method com.google.android.gms.common.api.GoogleApiClient.isConnected, referenced........

看起来您使用的库与您在编译时使用的库不同。
