我正在尝试使用ActionBarCompat，但FileNotFoundException在模拟器（API 7）中运行应用程序时得到了一个：

当我在 API 14 中运行应用程序时，它工作得很好。这是我的 Gradle 构建：
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.5.+'
}
}
apply plugin: 'android'
dependencies {
compile files('libs/volley.jar')
compile files('libs/jsoup-1.7.2.jar')
compile 'com.android.support:support-v4:18.0.+'
compile 'com.android.support:appcompat-v7:18.0.+'
}
android {
compileSdkVersion 18
buildToolsVersion "18.0.0"
defaultConfig {
minSdkVersion 7
targetSdkVersion 16
}
}
我FragmentActivity改为：ActionBarActivity_BaseActivity

有人可以帮我解决这个小问题吗？
