为什么我的应用程序不能 运行 在旧设备上？
Why is my app not running on an older device?
我的应用程序在 android 牛轧糖和奥利奥上运行良好，但当我想在像棒棒糖这样的低版本中打开时，运行 就不行了。
我已将 minSdkVersion 设置为 15，但无法正常工作。
如果您发现任何导致问题的原因，请告诉我。我在 android 应用程序开发方面还很陌生，这就是为什么我不明白这里出了什么问题。任何帮助深表感谢。提前致谢。
下面是我的build.gradle代码：
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.internexia.app.gemsv1"
minSdkVersion 15
targetSdkVersion 28
versionCode 1

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

如果您知道这里有什么问题或有任何其他建议，请帮助我。
一些 SVG 源似乎没有得到完全支持。在 activity 的 onCreate() 方法中添加以下行：
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
并确保在 XML 文件中使用以下作为 ImageView 的属性： app:srcCompact 而不是 android:src 来定义您的图片。
将所有图像文件从 drawable-v24 文件夹传输到 drawable 文件夹。
如果您简单地移动文件，错误将会消失并且它会正常工作。
