Android 应用程序未使用minSdk 21启动

直到最近，我的应用程序运行良好。然后，我将compileSdk和buildTools更新为25。从那时起，我的应用程序在打开时立即崩溃。将minSdkVersion设置为18可以解决问题，但当我将其设置为21时，就会发生这种情况。 附加堆栈跟踪和我的gradle文件的一部分

我在这里多次看到这些堆栈跟踪错误，但没有明确的问题答案

我尝试过清理和重建，清理Android Studio缓存，更新gradle版本和插件。对我来说似乎什么都不管用

编辑1

问题似乎在于一个或多个android支持库

compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.android.support:support-v4:25.1.0'
compile 'com.android.support:cardview-v7:25.1.0'
compile 'com.android.support:recyclerview-v7:25.1.0'

将它们全部恢复到24.1.0似乎可以解决这个问题。但是，我正在使用它们的更高版本中的一些功能，因此这没有帮助。

我也有同样的问题。我通过做两件事解决了这个问题

将以下内容添加到应用程序的

build.gradle

文件中

安卓{
...
德克斯选项{
preDexLibraries错误
}
}

对我来说，它崩溃是因为RxJava2行为主题的ClassNotFoundException，因此禁用库的predex解决了它

禁用项目中的即时运行。取消选中

Settings->Build，Execute，Deployment->Instant Run->Enable Instant Run

您是否碰巧使用了任何本机库？我继续使用CompileSDK版本24进行编译，以解决大量随机错误。您正在运行什么设备？哪个API版本？多个设备和API级别。模拟器、魅族m3s、SG note 5、Android 5.1和6可能您可以尝试以下方法。你可能必须创建你的自定义应用程序类，并启用Multidex（别忘了注册这个类）。我在棒棒糖设备上似乎也有同样的问题。棉花糖或更新的没有问题，但是在棒棒糖上，如果我把minSdk设置为21，我会得到同样的stacktrace和crash。设置minSdk=19，也可以在棒棒糖上使用。我有多索引支持库和应用程序扩展多索引应用程序。你找到解决办法了吗？或者Android工具链和/或支持库中的bug？
