Question

我试图从内存中获取位图的Uri。我这样做：

public static Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "title", null);
    return Uri.parse(path);
}

这种方法建议大多数 stackoverflow 问题。它在Nougat上运行良好。但它在棉花糖上崩溃了。这是错误：

我做错了什么吗？或者至少还有其他方法来获取位图吗？
