【问题描述】：

当我尝试运行我使用 android studio 和 java 创建的 android 应用程序时出现异常。看起来它不会破坏我的应用程序，但它会在我的控制台中显示每一次时间。

【解决方案1】：

你可以使用androidx.core 依赖来避免这个崩溃

dependencies {
   def core_version = "1.3.2"
   
   // Java language implementation
   implementation "androidx.core:core:$core_version"

   // Kotlin
   implementation "androidx.core:core-ktx:$core_version"

   ...
}
