某些 android 手机上的 NoSuchMethodError

Question

我正在使用值动画器通过动画更改状态栏颜色，在我的 phone 和模拟器上效果很好，但是当我将它发送给另一个人时，它因 NoSuchMethodError 而崩溃，我不能'不知道为什么，

如果在某些 phone 上有可用的方法，我将如何检查？
还有其他方法可以为状态栏设置动画颜色变化吗？

代码如下：

final ValueAnimator statusBarAnimator = ValueAnimator.ofArgb
            (ContextCompat.getColor(MainScreen.this, R.color.colorPrimary),
                    ContextCompat.getColor(MainScreen.this, R.color.colorPrimaryDark));
    statusBarAnimator.setDuration(500);
    statusBarAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        // how it works is that every time it updates, it goes to change the color by a little bit
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {
            if (Build.VERSION.SDK_INT >= 21) {
                getWindow().setStatusBarColor((Integer) statusBarAnimator.getAnimatedValue());
            }
        }
    });

错误代码在这里（来自崩溃分析）：

Answer 1

ValueAnimator.ofArgb() was added in API21. To achieve this effect on lower API's, use ArgbEvaluator（在 API11 中添加）。
