Android应用链接验证失败问题排查求助

• 可通过命令 adb shell am start -W -a android.intent.action.VIEW -d https://example.com/ com.example.app 直接启动应用
• 仅执行 adb shell am start -W -a android.intent.action.VIEW -d https://example.com/ 时，无法唤起应用，链接会通过Chrome打开
• 应用com.example.app的「应用信息 > 默认打开 > 已验证链接」为空且置灰
• 执行 adb shell pm get-app-links com.example.app 无任何输出
• 安装应用、打开应用并保持20秒以上，或执行 adb shell pm verify-app-links --re-verify 重新验证时，用 adb logcat -e "(IntentFilterIntentOp|IntentFilterIntentSvc)" 未捕获到相关日志
• 执行 curl https://example.com/.well-known/assetlinks.json -I 返回以下响应：

  该assetlinks.json内容如下，其中SHA256签名与发布APK所用密钥签名匹配：

  [
      {
          "relation": ["delegate_permission/common.handle_all_urls"],
          "target": {
              "namespace": "android_app",
              "package_name": "com.example.com",
              "sha256_cert_fingerprints": ["SO:ME:FA:KE:SH:A2:56:5C:57:D7:22:D4:ED:A3:C4:97:23:A2:4E:B0:30:93:A5:57:39:98:B1:E0:3E:03:64:73"]
          }
      }
  ]
  

• 执行 curl "https://digitalassetlinks.googleapis.com/v1/statements:list?source.web.site=https://example.com&relation=delegate_permission/common.handle_all_urls" 返回以下JSON：

  {
    "statements": [
      {
        "source": {
          "web": {
            "site": "https://example.com."
          }
        },
        "relation": "delegate_permission/common.handle_all_urls",
        "target": {
          "androidApp": {
            "packageName": "com.example.app",
            "certificate": {
              "sha256Fingerprint": "SO:ME:FA:KE:SH:A2:56:5C:57:D7:22:D4:ED:A3:C4:97:23:A2:4E:B0:30:93:A5:57:39:98:B1:E0:3E:03:64:73"
            }
          }
        }
      }
    ],
    "maxAge": "589172.377669267s"
  }
  

• 仅执行 adb shell pm get-app-links --user cur com.example.app 时得到以下输出：

  User 0:
        Verification link handling allowed: true
        Selection state:
          Disabled:
            example.com
  

• 已在应用清单中添加自定义URL Scheme，功能正常。

测试设备为Android 13（一加Nord 2）和Android 12设备，未找到adb shell pm get-app-links com.example.app无输出情况的相关文档。
