java.lang.OutOfMemoryError: Failed to allocate a 8294412 byte allocation with 8279288 free bytes and 7MB until OOM

问题出现的操作：
连续操作几次进入页面再退出时出现。

问题相关代码：
AbstractViewHelper.class
protected Bitmap getBitmapWithView(View v) {
Bitmap bitmap = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Bitmap.Config.ARGB_8888); // 引起OOM的代码
Canvas canvas = new Canvas(bitmap);
v.draw(canvas);
canvas.setBitmap(null);
return bitmap;
}

BaseViewHelper.class
public void backActivity(Activity mActivity, int resultCode, Intent mIntent) {
//省略部分代码
inflate.setBackgroundDrawable(new BitmapDrawable(getBitmapWithView(viewGroup)));
//省略部分代码
}
