我在使用BitmapFactory加载动画时遇到了内存异常

Question

我有6张图像作为动画加载在一起，它们存储在mFrame中。在调用较小的方法加载它们之前，下面的方法准备这些图像。我有时在尝试加载它时会遇到OutOfMemoryError。我用另一种方法加载图像：mImageView.setImageDrawable（mAnimHardRef）; mAnimHardRef.start（）;

private void loadAnimationAsync() {
    AsyncTask.execute(new Runnable() {
        @Override
        public void run() {
            long time = System.currentTimeMillis();
            final AnimationDrawable drawable = new AnimationDrawable();
            drawable.setOneShot(true);
            for(int frRes : mFrames) {
                Bitmap temp = BitmapFactory.decodeResource(mActivity.getResources(), frRes);
                temp = Bitmap.createScaledBitmap(temp, temp.getWidth() / 6, temp.getHeight() / 6, false);
                drawable.addFrame(new BitmapDrawable(temp), 60);
            }
            mAnimSoftRef = new SoftReference<AnimationDrawable>(drawable);
            mAnimHardRef = drawable;
            if (mShowAnim) mActivity.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    if (mShowAnim) showAnimationNow();
                }
            });
            Log.d("Joshua", "BG load time: " + (System.currentTimeMillis() - time));
        }
    });

}
