我一直在尝试在我的 Android Flutter 应用程序中实现 AppLink，该应用程序目前处于开发/调试模式，但 AppLink 不起作用。当我通过在调试/开发模式下运行 Flutter 应用程序的手机中的浏览器点击 URL 时，该应用程序无法打开。我认为 Flutter 应用程序实现内部存在一些问题。
创建了
assetlinks.json [
{
"relation": [
"delegate_permission/common.handle_all_urls"
],
"target": {
"namespace": "android_app",
"package_name": "com.foxjek.fox_jek_user",
"sha256_cert_fingerprints": [
"73:EA:74:0C:B4:6B:99:37:C0:CF:B9:BD:54:EB:2C:51:04:5A:3A:6A:0E:64:0B:27:B8:73:B2:51:4B:B3:CE:F9"
]
}
}
]
并上传到服务器上
root.well-known现在我已经按照此处定义的步骤安装了用于AppLinking实现的uni_link 0.5.1
库之后，我按照以下步骤设置一切：
这是我的

Dart 代码更新为：
void main() {
runApp(const MyApp());
initUniLinks();
}
void initUniLinks() async {
// Initialize the UniLinks plugin
print("Initialize the UniLinks plugin");
try {
await getInitialLink();
} on PlatformException {
// Handle exception/error as needed
print("Handle exception/error as needed");
}
// Listen for incoming deep links
// Attach a listener to the stream
print("Listen for incoming deep links");
linkStream.listen((String? uri) {
// Handle the deep link URI
print("Handle the deep link URI");
print(uri);
} , onError: (err) {
// Handle error, if any
print("Handle error, if any");
});
}
在设备上重建并重新安装 Flutter 应用程序以使更新生效。
但是，现在当我在设备浏览器中访问域 your-domain.com 时（在调试模式下运行 Flutter 应用程序的同一设备），设备无法识别 DeepLink/AppLink 来打开应用程序。
您可以通过运行此命令来测试应用程序 https://docs.flutter.dev/cookbook/navigation/set-up-app-links
adb shell 'am start -a android.intent.action.VIEW \
-c android.intent.category.BROWSABLE \
-d "http://<web-domain>/details"' \
