android - 警告 : ClassLoader referenced unknown path in Android Studio 2. 1.2

Question

我是 Android 和 Android Studio 的新手。我在 Android Studio 中创建了一个 HelloWorld 项目。当我在我的设备上运行该应用程序时，我收到以下警告。我该如何修复这些警告？

6-15 11:21:22.287 962-962/com.rajiv.helloworld W/System: ClassLoader referenced unknown path: /data/app/com.rajiv.helloworld-1/lib/arm

06-15 11:21:23.424 962-962/com.rajiv.helloworld W/art: Before Android 4.1, method android.graphics.PorterDuffColorFilter android.support.graphics.drawable.VectorDrawableCompat.updateTintFilter(android.graphics.PorterDuffColorFilter, android.content.res.ColorStateList, android.graphics.PorterDuff$Mode) would have incorrectly overridden the package-private method in android.graphics.drawable.Drawable

Answer 1

这是 instant-Run 的问题，如文档所述，在 Android 4.1 之前发出警告:

Instant Run is supported only when you deploy the debug build variant, use Android Plugin for Gradle version 2.0.0 or higher, and set minSdkVersion to 15 or higher in your app's module-level build.gradle file. For the best performance, set minSdkVersion to 21 or higher.

你可以看到完整的documentation在这里。

建议禁用Instant-run或将min-sdk设置为15或更高。
