给个可以复现问题的简单示例。

在 Uni-app 中，如果在 Android 平台上播放视频并打开摄像头确认后出现崩溃问题，可能是由于以下原因之一导致的。以下是一些可能的解决方案和排查步骤：

1. 检查权限

确保应用已经正确获取了摄像头和存储权限。在 manifest.json 中添加以下权限：

{
  "permission": {
    "android": {
      "request": [
        "android.permission.CAMERA",
        "android.permission.WRITE_EXTERNAL_STORAGE",
        "android.permission.READ_EXTERNAL_STORAGE"
      ]
    }
  }
}

在代码中动态请求权限：

uni.authorize({
  scope: 'scope.camera',
  success() {
    console.log('摄像头权限已授权');
  },
  fail() {
    console.log('摄像头权限未授权');
  }
});

2. 检查生命周期

在打开摄像头或播放视频时，确保正确处理了页面的生命周期。例如，在 onHide 或 onUnload 中释放资源：

onUnload() {
  // 释放视频播放器或摄像头资源
  this.videoContext && this.videoContext.destroy();
}

3. 检查视频播放器组件

如果使用 video 组件播放视频，确保正确初始化和销毁视频播放器：

<video id="myVideo" src="video.mp4" controls></video>

onReady() {
  this.videoContext = uni.createVideoContext('myVideo');
},
onUnload() {
  this.videoContext && this.videoContext.destroy();
}

4. 检查摄像头组件

如果使用 camera 组件，确保正确初始化和销毁摄像头：

<camera id="myCamera" device-position="back"></camera>

onReady() {
  this.cameraContext = uni.createCameraContext('myCamera');
},
onUnload() {
  this.cameraContext && this.cameraContext.stopRecord();
}

5. 检查返回逻辑

在返回页面时，确保没有重复调用摄像头或视频播放器的销毁方法。可以在 onBackPress 中处理返回逻辑：

onBackPress() {
  // 释放资源
  this.videoContext && this.videoContext.destroy();
  this.cameraContext && this.cameraContext.stopRecord();
  return false; // 阻止默认返回行为
}

6. 检查日志

通过 Android Studio 或 adb logcat 查看崩溃日志，定位具体错误。常见的错误可能包括：

  • 权限未授权
  • 资源未释放
  • 内存泄漏

7. 更新 Uni-app 版本

确保使用的是最新版本的 Uni-app 和 HBuilderX，旧版本可能存在兼容性问题。

8. 测试真机

在真机上测试，模拟器可能存在兼容性问题。

9. 示例代码

以下是一个完整的示例代码，结合了视频播放和摄像头功能：

<template>
  <view>
    <video id="myVideo" src="video.mp4" controls></video>
    <camera id="myCamera" device-position="back"></camera>
    <button @click="openCamera">打开摄像头</button>
  </view>
</template>

<script>
export default {
  data() {
    return {
      videoContext: null,
      cameraContext: null,
    };
  },
  onReady() {
    this.videoContext = uni.createVideoContext('myVideo');
    this.cameraContext = uni.createCameraContext('myCamera');
  },
  onUnload() {
    this.videoContext && this.videoContext.destroy();
    this.cameraContext && this.cameraContext.stopRecord();
  },
  methods: {
    openCamera() {
      uni.authorize({
        scope: 'scope.camera',
        success() {
          console.log('摄像头权限已授权');
        },
        fail() {
          console.log('摄像头权限未授权');
        },
      });
    },
  },
};
</script>
