Question

我正在尝试将位图添加到谷歌地图标记图标。

以下是我将代码添加到标记图标的代码。由于位图大小

，应用程序崩溃

错误：java.lang.IllegalArgumentException：dimension4096x8192的纹理大于支持的最大大小4096x4096

BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        int imageHeight = options.outHeight;
        int imageWidth = options.outWidth;
        String imageType=options.outMimeType;
        if(imageWidth > imageHeight) {
            options.inSampleSize = calculateInSampleSize(options,10,10);//if landscape
        } else{
            options.inSampleSize = calculateInSampleSize(options,10,10);//if portrait
