分支 io - 通过 Play 商店安装应用程序后没有引用参数

【中文标题】分支 io - 通过 Play 商店安装应用程序后没有引用参数

【英文标题】：Branch io - No referringParams after app is installed via play store

【发布时间】：2020-10-15 14:55:54

【问题描述】：

我有两个问题：

主要问题是，如果我的手机 (android) 上没有安装该应用程序，那么分支链接会发送我通过 Play 商店安装它，但是在我安装并从那里打开它之后，我没有深层链接数据。

如果该应用程序已经安装并且我单击分支链接，我需要选择通过 chrome 或通过应用程序打开它， 如果我选择 chrome -> 再次没有深层链接数据。

这是源代码：

MainApp.java

public class MainApp extends AppCompatActivity 


@Override
protected void onCreate(Bundle savedInstanceState) 

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);



@Override public void onStart() 
    super.onStart();
    try 
        Branch.sessionBuilder(this).withCallback(new Branch.BranchReferralInitListener() 
            @Override
            public void onInitFinished(JSONObject referringParams, BranchError error) 
                if (error == null) 

                    // option 3: navigate to page
                    Intent intent = new Intent(MainApp.this, Main2Activity.class);
                    startActivity(intent);
                    

                 else 
                    Log.i("BRANCH SDK", error.getMessage());
                
            
        ).withData(this.getIntent().getData()).init();

    
    catch (Exception e) 
        e.printStackTrace();
    


@Override
protected void onNewIntent(Intent intent) 
    super.onNewIntent(intent);
    try 
        setIntent(intent);
        // if activity is in foreground (or in backstack but partially visible) launching the same
        // activity will skip onStart, handle this case with reInitSession
        Branch.sessionBuilder(this).withCallback(branchReferralInitListener).reInit();
    
    catch (Exception ignored)  



private Branch.BranchReferralInitListener branchReferralInitListener = new Branch.BranchReferralInitListener() 
    @Override
    public void onInitFinished(JSONObject linkProperties, BranchError error) 
        // do stuff with deep link data (nav to page, display content, etc)
    
;

Main2Activity.java

公共类 Main2Activity 扩展 AppCompatActivity

【参考方案1】：

正确的Manifest.xml文件应该是这样的-

<meta-data
    android:name="com.facebook.sdk.ApplicationId"
    android:value="@string/facebook_app_id" />

<activity
    android:name=".MainApp">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

    <!-- Branch URI Scheme -->
    <intent-filter>
        <data android:scheme="hello" />
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
    </intent-filter>

<!-- Branch App Links (optional) -->
<intent-filter android:autoVerify="true">
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="https" android:host="2rerz.app.link" />
    <!-- example-alternate domain is required for App Links when the Journeys/Web SDK and Deepviews are used inside your website.  -->
    <data android:scheme="https" android:host="2rerz-alternate.app.link" />
</intent-filter>
</activity>

<!-- Branch init -->
<meta-data android:name="io.branch.sdk.BranchKey" android:value="key_live_jeVWU2AYfrIjpJmslgNxZgjeAwcUzcqK" />
<meta-data android:name="io.branch.sdk.BranchKey.test" android:value="key_test_hlxrWC5Zx16DkYmWu4AHiimdqugRYMr" />
<meta-data android:name="io.branch.sdk.TestMode" android:value="false" />     <!-- Set to true to use Branch_Test_Key (useful when simulating installs and/or switching between debug and production flavors) -->


<activity android:name=".MainActivity" />
<activity android:name=".Main2Activity" >
</activity>

此外，请确保您使用正确的 API 密钥和您正在使用的链接。如果是 Live Link，则使用 Live API 密钥，反之亦然。
