如何查找Android应用的应用名/Intent名称，实现跨应用启动自有应用

Hey there! Let me break down exactly how to set up a custom URL scheme for your app—this is the same mechanism that powers market:// for Google Play and instagram:// for Instagram. The "app name" you're trying to use isn't something that exists by default; you have to manually define this scheme in your app's configuration.

Android Setup #

To get myapp://login working on Android, you need to add an intent filter to the Activity you want to launch (like your LoginActivity) in your AndroidManifest.xml:

<activity android:name=".LoginActivity">
    <!-- Intent filter to handle custom URL scheme -->
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        
        <!-- This defines your custom scheme and host -->
        <data
            android:scheme="myapp"
            android:host="login" />
    </intent-filter>
</activity>

• Testing: You can test this right away with an ADB command:

  adb shell am start -W -a android.intent.action.VIEW -d "myapp://login" com.your.app.package
  

  Or try typing myapp://login into a mobile browser—if your app is installed, it should launch directly to the LoginActivity.

• Pro Tip: Use a unique scheme to avoid conflicts with other apps. Instead of just myapp, consider using your app's reverse domain (e.g., com.yourcompany.myapp) as the scheme.

iOS Setup #

For iOS, you'll configure the scheme in your project's Info.plist and add code to handle the incoming URL:

1. Add the URL Scheme:

   • Open Xcode, go to your project's Info.plist
   • Right-click and select "Add Row", then choose URL types
   • Expand URL types, add an entry, set URL Schemes to myapp (or your unique scheme), and fill Identifier with your app's Bundle ID.

2. Handle the URL:
   In either your SceneDelegate (iOS 13+) or AppDelegate, add code to route the URL to the right screen:

   // SceneDelegate.swift (iOS 13+)
   func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
       guard let url = URLContexts.first?.url else { return }
       
       if url.scheme == "myapp" && url.host == "login" {
           // Navigate to your LoginViewController here
           let loginVC = LoginViewController()
           // Add your navigation logic (e.g., push to navigation stack)
       }
   }
   
   // AppDelegate.swift (older iOS versions)
   func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
       if url.scheme == "myapp" && url.host == "login" {
           // Handle login screen navigation
           return true
       }
       return false
   }
   

• Testing: Open Safari on your simulator/device and type myapp://login—your app should launch and trigger the navigation logic you added.

Key Notes #

• Always ensure your scheme is unique to avoid collisions with other apps. Using your app's Bundle ID as part of the scheme is a safe bet.
• If the app isn't installed, tapping the custom URL will fail—you can add a fallback (like redirecting to your app store page) for web links.
• Some browsers or apps might block custom schemes, so test thoroughly across different launch sources.

Hope this gets your custom URL scheme working smoothly! If you run into platform-specific issues, feel free to dive deeper into the details for your OS.
