我使用 Android Studio 2.0 和支持VectorDrawable库。我的毕业典礼：

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        minSdkVersion 8
        vectorDrawables.useSupportLibrary = true
    }

    aaptOptions {
        additionalParameters "--no-version-vectors"
    }
}

但是当我尝试在旧设备的菜单中加载图标时：

MenuItem miSubjects = menu.add(R.id.menu_navigation, ACTION_SUBJECTS_ID, order, R.string.action_subjects);
miSubjects.setIcon(ContextCompat.getDrawable(this, R.drawable.ic_labels_gray_24dp));

图标是一个矢量，但 AndroidStudio 必须为旧版本生成和绘制（光栅可绘制）。如果不是这样，我需要如何使用它？
向量示例ic_labels_gray_24dp.xml

<vector
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportHeight="24.0"
    android:viewportWidth="24.0">
    <path
        android:fillColor="#8a000000"
        android:pathData="m15.316,4.5 l-10.316,0.008c-1.169,-0 -2,0.96 -2,2v5.984c0,1.043 0.78,2 2,2l10.316,0.008c0.991,0 0.968,0.014 1.543,-0.6l4.141,-4.4 -4.141,-4.4c-0.594,-0.594 -0.552,-0.6 -1.543,-0.6zM20.019,13.459 L18.316,15.269c-0.284,0.303 -0.614,0.743 -1.354,1.027 -0.741,0.285 -1.161,0.203 -1.646,0.203h-0.002l-10.316,-0.008c-0.74,0 -1.413,-0.225 -1.998,-0.578v1.578c0,1.043 0.78,2 2,2l10.316,0.008c0.991,0 0.968,0.014 1.543,-0.6l4.141,-4.4 -0.98,-1.041z"/>
</vector>

PS它写了一个简单的类。它不能修复 Android Studio 错误，但至少应用程序不会崩溃。也许其他人也有同样的问题。

public final class VectorDrawable {

    private VectorDrawable() {}

    public static Drawable getDrawable(Context context, final int id) {
        return VectorDrawableCompat.create(context.getResources(), id, context.getTheme());
    }
}
