我的应用程序在切换到 v23 之前运行良好（之前的配置是 v22 并支持库 v22.2.1。升级后，编译正确完成，但仅在启动时出现此错误。
我在 SO 上看到过很多帖子，其中的问题来自糟糕的样式，带有 Holo parent。棘手的问题在 Manifest 文件中找到了它们的起源，其中 activity 主题覆盖了应用程序主题。
这是我的情况，所以出于测试目的我将清单更改为：
<application
android:name=".MyApplication"
android:allowBackup="true"
android:hardwareAccelerated="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:theme="@style/Theme.BaseMyApp">
<!-- Launch activity. MyApp.Theme has Theme.BaseMyApp for parent, but has 2 more attributes for v21 -->
<activity
android:name=".activities.HomeActivity"
android:launchMode="singleTop"
android:theme="@style/MyApp.Theme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
...但是，奇怪，还是报错！我还检查了 activity 布局的视图，但似乎没有什么问题，只有一个主题扩展了 AppCompat:
的工具栏
toolbar_layout.xml
<merge xmlns:android="http://schemas.android.com/apk/res/android"

<android.support.v7.widget.Toolbar

哪里

你知道我哪里搞砸了吗？
谢谢
感谢您的更新。也许您的工具栏 parent 是问题所在。它比 Theme.AppCompat.
有另一种继承
<style name="AppTheme.Toolbar" parent="ThemeOverlay.AppCompat.ActionBar">
<!-- Customize color of navigation drawer icon and back arrow -->
<item name="colorControlNormal">@android:color/white</item>
</style>
尝试将其用于您的工具栏：
"Widget.AppCompat.Toolbar"
作为parent
问题部分解决。
有罪的一行是：
at android.support.v7.app.k.onCreate(AppCompatDelegateImplBase.java:124)
我使用 these separate ProGuard files 配置 ProGuard。也许我没有指向正确的 /app/proguard 目录。因此，ProGuard 忽略了 myapp-rules.pro 我说要保留那些 android.support.v7.**类.
修复此问题后，出现错误：
