android 系统尝试绘制大尺寸位图(崩溃报告)

Question

在开发者控制台中，我得到以下崩溃报告。我真的不知道问题出在哪里。这是我指向该项目的 GitHub 链接:https://github.com/DaFaack/Mr.Politik

此错误消息是什么意思，我该如何解决？

Answer 1

From source :

protected void throwIfCannotDraw(Bitmap bitmap) {
    super.throwIfCannotDraw(bitmap);
    int bitmapSize = bitmap.getByteCount();
    if (bitmapSize > MAX_BITMAP_SIZE) {
        throw new RuntimeException(
                "Canvas: trying to draw too large(" + bitmapSize + "bytes) bitmap.");
    }
}

并在文件顶部定义:

private static final int MAX_BITMAP_SIZE = 100 * 1024 * 1024; // 100 MB

至于在您的来源中哪里抛出了错误？根据已发布的内容，我知道的甚至比你少。尝试找到您可能绘制大图像的地方，并验证它们不大于 100MB。
