Android 某些设备上的膨胀错误导致强制关闭
Android inflating errors on some devices that causes force close
我正在开发一个 android 应用程序，我已经在 Android 7 上测试了这个应用程序，它运行良好。但最后我决定在较低版本上测试它并感到惊讶。
在开始一些活动时，我遇到了很多膨胀错误。
这是我的应用 gradle 文件：
apply plugin: 'com.android.application'

versionCode 0

vectorDrawables.useSupportLibrary = true
}
buildTypes {

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {

您的 FloatingActionButton 中有一个属性 android:backgroundTint，根据 View.setBackgroundTintList，它仅在 Android API 21 及更高版本中可用，这就是您在 API 级别较低的设备上遇到崩溃的原因。要修复向后兼容性问题，请尝试将属性替换为 app:backgroundTint:

您的 FloatingActionButton 中有一个属性 android:backgroundTint，根据 View.setBackgroundTintList，它仅在 Android API 21 及更高版本中可用，这就是您在 API 级别较低的设备上遇到崩溃的原因。要修复向后兼容性问题，请尝试将属性替换为 app:backgroundTint:
