资源$ NotFoundException在API 22上使用矢量图像但在API 24上不使用

问题描述 投票：-1回答：2

我在Android中使用vector时遇到了问题。

我正在使用矢量（来自android studio中导入的SVG）使用Textview显示图像作为我的android:background="@drawable/ic_blue2"的背景

虽然在使用API​​24的手机上进行测试时一切运行良好，但应用程序在启动时会在具有InflateException和Resources $ NotFoundException的API22的手机上崩溃。

我尝试过以前的帖子的答案，例如添加到Gradle vectorDrawables.useSupportLibrary = true，但它没有用。

我正在使用Android Studio 3.0.1和Gradle 3.0.1。请注意，我的活动扩展了“活动”，而不是AppCompatActivity（不知道它在这里是否重要）。

这是布局的代码：

旧的API级别不存在对XML中的矢量绘图的本机支持。您可以在ImageViews中使用它们，因为它具有特殊的app:srcCompat属性，但您不能将它们用于android:background等。

但是，您可以在Java中使用它们。就像是

Button b = findViewById(R.id.buttonSolo);
Drawable d = ContextCompat.getDrawable(this, R.drawable.ic_blue2);
b.setBackground(d);

应该适用于所有API级别。

从pastebin中的（更新）链接到您的资产，看起来您正在使用新的XML包格式。注意<aapt:attr name="android:fillColor">节点。参见this G+ post的Nick Butcher。即使它是关于动画矢量drawables，它适用于您的情况，因为我确信机制是相同的。

要检查的重要一点是：

这需要Build Tools 24+（目前在RC中），但输出是向后兼容的。

因此，可以检查您的构建工具是否已更新。
