java.lang.NoClassDefFoundError: android.support.v7.app.AppCo

Question

突然之间，当我尝试编译我的项目并运行我的应用程序时，我开始收到这个运行时错误-

java.lang.NoClassDefFoundError: android.support.v7.app.AppCompatDelegateImplV14
            at android.support.v7.app.AppCompatDelegate.create(AppCompatDelegate.java:93)

            at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:698)

这是我尝试做的事情：

1）从我的所有依赖项中排除support-v4并手动指定旧版本，支持compile 'com.android.support:support-v4:21.+'。

有趣的是，MainActivity 不是我的启动器活动。因此，该应用程序在启动器活动中运行良好。但是一旦主活动打开，它就会失败。

我的build.gradle在下面给出（我不得不搞砸它来修复另一个设计库错误，所以不要介意排除）

Answer 1

从您公开的所有排除项中，我不得不说我读到的是，您刚刚禁止support-v4和support-v7您的应用程序（甚至来自design和appcompat）。

所以尽量把它们放在最后^^

compile 'com.android.support:appcompat-v7:22.2.0' // no exclusion

Answer 2

对我来说

，解决方案一直在添加

android:name="android.support.multidex.MultiDexApplication"

到清单

Answer 3

只需启用multidex。这对我有用。请点击链接 https://stackoverflow.com/a/31724383/3040893
