Firebase动态链接，使用一次后清除

Question

声明

调用getDynamicLink（）将检索链接并清除数据，以便应用程序只处理一次。

我从文档中复制了以下代码。

FirebaseDynamicLinks.getInstance()
        .getDynamicLink(getIntent())
        .addOnSuccessListener(this, new OnSuccessListener<PendingDynamicLinkData>() {
            @Override
            public void onSuccess(PendingDynamicLinkData pendingDynamicLinkData) {
                // Get deep link from result (may be null if no link is found)
                Uri deepLink = null;
                if (pendingDynamicLinkData != null) {
                    deepLink = pendingDynamicLinkData.getLink();
                }


                // Handle the deep link. For example, open the linked
                // content, or apply promotional credit to the user's
                // account.
                // ...

                // ...
            }
        })
        .addOnFailureListener(this, new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Log.w(TAG, "getDynamicLink:onFailure", e);
            }
        });

如果我把上面的代码放在mainactivity:oncreate上

• 当应用程序不在后台运行时，深度链接工作正常
• 当应用程序在后台运行时，无法识别深层链接(onsuccess回调不会被调用）

如果我把上面的代码放在mainactivity:onstart上

• 当应用程序是否在后台运行时，深度链接都能正常工作
• 如果用户单击deep link，main activity会获得它并打开approapriate activity，（工作正常），但是当他试图返回主活动时，onsuccesscallback再次激发，他永远无法进入主活动。

您的MainActivity应该如下所示

@Override
protected void onCreate(Bundle savedInstanceState) {
    //...

    FirebaseDynamicLinks.getInstance()
            .getDynamicLink(getIntent())
            .addOnSuccessListener(this, new OnSuccessListener<PendingDynamicLinkData>() {
                @Override
                public void onSuccess(PendingDynamicLinkData pendingDynamicLinkData) {
                    // Get deep link from result (may be null if no link is found)
                    Uri deepLink = null;
                    if (pendingDynamicLinkData != null) {
                        deepLink = pendingDynamicLinkData.getLink();
                    }


                    // Handle the deep link. For example, open the linked
                    // content, or apply promotional credit to the user's
                    // account.
                    // ...


            })
            .addOnFailureListener(this, new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.w(TAG, "getDynamicLink:onFailure", e);
                }
            });
}

@Override
protected void onNewIntent(Intent intent) {
    //...

    FirebaseDynamicLinks.getInstance()
            .getDynamicLink(intent)
            .addOnSuccessListener(this, new OnSuccessListener<PendingDynamicLinkData>() {
                @Override
                public void onSuccess(PendingDynamicLinkData pendingDynamicLinkData) {
                    // Get deep link from result (may be null if no link is found)
                    Uri deepLink = null;
                    if (pendingDynamicLinkData != null) {
                        deepLink = pendingDynamicLinkData.getLink();
                    }


                    // Handle the deep link. For example, open the linked
                    // content, or apply promotional credit to the user's
                    // account.
                    // ...


            })
            .addOnFailureListener(this, new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.w(TAG, "getDynamicLink:onFailure", e);
                }
            });
}
