AnimatedVectorDrawableCompat适配5.0以下安卓

*首先 
VectorDrawableCompat依赖与AAPT的一些功能，它能保持最近矢量图使用的添加的属性ID，以便他们可以被v21之前的引用。

如果你没有启用这个标志，当你在KitKat上运行你的APP你会看到以下（或者类似）错误：

解决办法：启用标志位 

如果你正在用Gradle插件v2.0或者更高，我有一个简洁方法去启用它：

android {
  defaultConfig {
    vectorDrawables.useSupportLibrary = true
  }
}

如果你还没有更新，在用v1.5后者更低的版本，你需要在你的build.gradle文件里添加以下内容:

android {
  defaultConfig {
    
    generatedDensities = []
  }
  
  aaptOptions {
    additionalParameters "--no-version-vectors"
  }
}

ImageView androidImageView = (ImageView) findViewById(R.id.animated_vector_imgv);
AnimatedVectorDrawableCompat animatedVectorDrawableCompat = AnimatedVectorDrawableCompat.create(this, R.drawable.animated_vector);
androidImageView.setImageDrawable(animatedVectorDrawableCompat);
((Animatable) androidImageView.getDrawable()).start();
