根因分析

请求了平台特定权限（如摄像头、位置、存储），但用户仅授予了有限范围，或者未在应用清单中声明该权限。

English

A platform-specific permission (e.g., camera, location, storage) was requested but the user granted only a limited scope, or the permission was not declared in the app manifest.

解决方案

  1. Use the permission_handler package to explicitly request the permission and check the status before performing the operation. Example: `final status = await Permission.camera.request(); if (status.isGranted) { // proceed } else { // show rationale }`
  2. Declare the exact permission in AndroidManifest.xml (e.g., <uses-permission android:name="android.permission.CAMERA" />) and in Info.plist (e.g., NSCameraUsageDescription).
  3. For Android 14+ granular media permissions, request each sub-permission (e.g., ACCESS_MEDIA_LOCATION) separately using the `photo_manager` or similar package that handles scoped storage.

无效尝试

常见但无效的做法:

  1. 50% 失败

    Over-declaring permissions may cause app store rejection or user distrust; also, runtime permission requests still require user consent and proper handling.

  2. 75% 失败

    Ignoring the result means the app proceeds without the required permission, leading to the same exception when the operation is attempted.

  3. 85% 失败

    Lowering compileSdkVersion may introduce security vulnerabilities and prevent use of newer APIs; it also does not resolve runtime permission denials on newer devices.
