我正在尝试与 FileProvider 共享文件。我检查了该文件是否与 gmail、google drive 等应用程序正确共享。即使抛出以下异常：

分享意向

Intent intentShareFile = new Intent(Intent.ACTION_SEND);
        File fileWithinMyDir = new File(targetPdf);

        if(fileWithinMyDir.exists()) {
            intentShareFile.setType("application/pdf"); …

我正在尝试上传从InkscapeAndroid Studio 中导出的 SVG 文件，Vector Asset但不幸的是我遇到了以下错误：

ERROR @line 35: Gradient has no stop info

定义渐变的代码：

<defs
     id="defs11210">
    <linearGradient
       inkscape:collect="always"
       id="linearGradient11815">
      <stop
         style="stop-color:#69aeed;stop-opacity:1"
         offset="0"
         id="stop11811" />
      <stop
         style="stop-color:#66e6b2;stop-opacity:0.90909094"
         offset="1"
         id="stop11813" />
       --&gt;
    </linearGradient>
    <radialGradient <!-- LINE 35-->
       inkscape:collect="always"
       xlink:href="#linearGradient11815"
       id="radialGradient928"
       cx="99.615288"
       cy="233.88142"
       fx="99.615288"
       fy="233.88142"
       r="80.842598"
       gradientTransform="matrix(1,0,0,1.3440437,0,-80.46542)"
       gradientUnits="userSpaceOnUse" />
  </defs>

我猜是xlink:href="#linearGradient11815"这个问题的原因，但我不明白为什么 Android Studio 无法识别停止信息是参考。

提前致谢。

我按照Moini 的建议更改了语法，但仍然不起作用：

<stop stop-color="#69aeed"
        stop-opacity="1"
        offset="0" />
<stop stop-color="#66e6b2"
        stop-opacity="0.90909094"
        offset="1" />
