getDrawable与AnimatedVectorDrawable在android 4中崩溃

Question

我尝试使用AnimatedVectorDrawable访问ContextCompat，如下所示。我使用下面的代码来做到这一点。它在5和更高版本中运行良好，但在4中却不起作用。

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
    private void startOpenAnimations() {

        // Icon
        AnimatedVectorDrawable menuIcon = (AnimatedVectorDrawable) ContextCompat.getDrawable(getContext(),
                R.drawable.ic_menu_animated);
        mFabView.setImageDrawable(menuIcon);
        menuIcon.start();

        // Reveal
        int centerX = mFabRect.centerX();
        int centerY = mFabRect.centerY();
        float startRadius = getMinRadius();
        float endRadius = getMaxRadius();
        Animator reveal = ViewAnimationUtils
                .createCircularReveal(mNavigationView,
                        centerX, centerY, startRadius, endRadius);

        // Fade in
        mNavigationMenuView.setAlpha(0);
        Animator fade = ObjectAnimator.ofFloat(mNavigationMenuView, View.ALPHA, 0, 1);

        // Animations
        AnimatorSet set = new AnimatorSet();
        set.playSequentially(reveal, fade);
        set.start();
    }

来自可绘制资源ID的android.content.res.Resources$NotFoundException:文件res/ drawable /ic_menu_activated.xml 0x7f020064 在android.content.res.Resources.loadDrawable(Resources.java:3451) at android.content.res.Resources.getDrawable(Resources.java:1894) at android.support.v4.content.ContextCompat.getDrawable(ContextCompat.java:354)

为什么在棒棒糖设备中不可能使用getDrawable和ContextCompat

我怎么能解决这个问题？

试试这个：AnimatedVectorDrawableCompat.create(this, R.drawable.animated_vector_name)
