我正在Android Studio中编写应用程序。它在Marshmallow上编译并完美运行，但是当我尝试使用Jelly Bean模拟器（API 16）执行它时，它会失败。我还尝试将compileSdkVersion更改为16，因此也更改了旧版本的所有依赖项，但它仍然无法正常工作。你能救我吗？
这是错误：

我认为问题在于Gradle构建设置。这是我的app build.gradle：
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.3"
defaultConfig {
applicationId "com.example.carlo.application"
minSdkVersion 15
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.android.support:design:24.2.1'
compile 'com.android.support:support-v4:24.2.1'
compile 'com.android.support:cardview-v7:24.2.1'
testCompile 'junit:junit:4.12'
compile 'com.android.support:gridlayout-v7:24.2.1'
}
和我的项目build.gradle：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
答案 0 :(得分：1)
错误消息中有几条关键线：
Caused by: android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path)
...
at android.support.v7.view.menu.MenuItemImpl.getIcon(MenuItemImpl.java:421)
...
at android.support.design.widget.NavigationView.inflateMenu(NavigationView.java:248)
所以这与gradle无关，但是你在NavigationView找不到的图标之一。仔细检查您的图标在API 16上是否有效（例如，它们不仅位于drawable-v21文件夹中）。
