问题描述

对于我的Android应用程序,我在Google Play的开发者控制台中收到以下错误:

For my Android application, I get the following error in Google Play's developer console:

java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{PACKAGE_NAME/PACKAGE_NAME.MainActivity}: java.lang.ClassNotFoundException: PACKAGE_NAME.MainActivity in loader dalvik.system.PathClassLoader[/mnt/asec/PACKAGE_NAME-1/pkg.apk]

虽然这个错误很少出现(可能会被忽略),但我发现这个更简单的是有一个无错误的开发者控制台:)而且,我只会喜欢知道这个错误的原因。

Although this error appears extremely rarely (and can probably be neglected), I find it cleaner to have a error-free developer console :) And furthermore, I would just like to know the causes for this error.

是的,好像有一个类c没有找到。但为什么?如何防止这种情况?

推荐答案

经过进一步的研究,我相信你是正确的事实,它绝对是一个用户错误。 [/ mnt / asec / PACKAGE_NAME-1 / pkg.apk] 很可能意味着他们正在尝试将您的应用移动到SD卡。请阅读这里:

Update(4/26/15):

After further research I believe you are right in the fact that its definitely a user error. The [/mnt/asec/PACKAGE_NAME-1/pkg.apk] most likely means they are trying to move your app to the SD card. Please read here:

这是一个Java RuntimeException as被Logcat看到。我没有看到这个事情发生在许多次之前,当我还没有添加活动清单正确。

This is a Java RuntimeException as seen by Logcat. I've seen this happen many times before when I have not added the Activity to manifest correctly.

java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{PACKAGE_NAME/PACKAGE_NAME.MainActivity}: java.lang.ClassNotFoundException: PACKAGE_NAME.MainActivity in loader dalvik.system.PathClassLoader[/mnt/asec/PACKAGE_NAME-1/pkg.apk]
