【问题标题】：image_picker crash in android app - Flutter Appandroid 应用中的 image_picker 崩溃 - Flutter App
【发布时间】：2021-05-27 18:23:56
【问题描述】：

首先，我尝试了这个answer，但问题仍然存在，我在新的模拟器上尝试了它，在一个真实的设备上，但我无法修复它。 它在IOS上成功运行。

好的，让我们看看问题：

  • 第一步正在工作，所以转到gallery 我在第二步中遇到了问题
  • 第二步：当我选择图像时，VS Code 失去与设备的连接，因此应用程序崩溃。 Emulator Photo When It Crash

这是输出：

【问题讨论】：

  • 运行flutter clean 一次并尝试。
  • 请确认在 manifirst 中声明活动无法找到明确的活动类 {com.example.gayidayi/com.yalantis.ucrop.UCropActivity};您是否在 AndroidManifest.xml 中声明了此活动？
  • 不是我不知道该怎么做，你能提供一些源代码或文档吗？或者直接回答
  • @Steve55 您正在使用任何额外的插件，例如用于裁剪图像或任何其他插件？
  • 是的，我正在使用image_cropper

标签： flutter dart imagepicker flutter-image flutter-android


【解决方案1】：

我终于找到了解决方案。 我也遇到了这个问题，这个解决方案对我有帮助。这里的问题是图像裁剪器包。所以图像裁剪包需要一个活动权限才能添加AndroidManifest.xml，所以对于android。

这里是许可：

<activity
    android:name="com.yalantis.ucrop.UCropActivity"
    android:screenOrientation="portrait"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>

这里是documentation of image cropper，你可以通过查看获得更多
