我的应用每次崩溃，并显示错误 “不幸的是，应用已停止” ，但在运行API 16 to 24的android模拟器上却在API 24上运行使用ImageView。但是，当删除Imageview时，它可以正常工作。我需要ImageView来构建项目。我该如何解决？下面是我的xml代码：

答案 0 :(得分：0)

“ @ drawable / logo”是矢量图像吗？如果是，则需要添加支持库以缓解依赖关系

等级：

defaultConfig {
    applicationId "com.app"
    minSdkVersion 15
    versionCode 1
    versionName "x"
    vectorDrawables.useSupportLibrary = true
}

dependencies {
//...
compile "com.android.support:support-vector-drawable:$appcompatVersion"
}
