当有人点击firebase动态链接时，如何在选择器应用中显示我的应用？

Question

如果有人点击动态链接，如果我想在选择器应用程序中显示我的应用程序，我的Android清单文件应该如何？ URL前缀类似于 - https://testapp.page.link。在那个阶段，如果有人点击链接，那么它首先打开浏览器然后重定向到我的应用程序。但我想在选择器应用列表中显示我的应用。这时我的清单文件如下 -

 <activity android:name=".extraActivities.DynamicLinkActivity">

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="test.com"
                android:pathPattern="https://testapp.page.link*"
                android:scheme="https"
               />


        </intent-filter>

    </activity>

Answer 1

我们需要在清单文件中编写intent-filter，如下所示 -

<intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="testapp.com"
                android:pathPattern=".*"
                android:scheme="https" />

            <data
                android:host="testapp.page.link"
                android:scheme="https"
                android:pathPattern=".*"/>

        </intent-filter>

其中“testapp.page.link”实际上是Firebase动态链接控制台左上角显示的URL前缀。而“testapp.com”是任何链接的第一部分。例如：https://testapp.com/user_profile?id=“Zsdsdjwenncsdmsd”。通过此链接，我们可以在动态链接的接收端将用户ID提取为“Zsdsdjwenncsdmsd”。一个完整的例子如下所示 -

如果有人点击分享按钮，则会创建动态链接 -

shareBtn.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        shareProgressBar.setVisibility(View.VISIBLE);
                        Task<ShortDynamicLink> shortDynamicLinkTask = buildDeepLink(getString(R.string.grp_post_link)+postsModel.getPostId()+"&groupKey="+postsModel.getGroupKey()+"&groupName="+ dataSnapshot.getValue(String.class));

                        shortDynamicLinkTask.addOnCompleteListener(new OnCompleteListener<ShortDynamicLink>() {
                            @Override
                            public void onComplete(@NonNull Task<ShortDynamicLink> task) {

                                grpPostsViewHolder.shareProgressBar.setVisibility(View.GONE);

                                if(task.isSuccessful()){
                                    Uri uri = task.getResult().getShortLink();
                                    share(dataSnapshot.getValue(String.class), uri.toString());
                                }else {
                                    Toast.makeText(context, "Can't create link", Toast.LENGTH_SHORT).show();
                                }

                            }
                        });

                        shortDynamicLinkTask.addOnFailureListener(new OnFailureListener() {
                            @Override
                            public void onFailure(@NonNull Exception e) {
                                shareProgressBar.setVisibility(View.GONE);
                            }
                        });

动态链接创建者功能和共享功能 -

 /*-----------------------------------------------------------------------------*/

private Task<ShortDynamicLink> buildDeepLink(String deepLink) {

    String uriPrefix = getString(R.string.dynamic_links_uri_prefix);

    return FirebaseDynamicLinks.getInstance().createDynamicLink()
            .setLink(Uri.parse(deepLink))
            .setDomainUriPrefix(uriPrefix)
            .setNavigationInfoParameters(new DynamicLink.NavigationInfoParameters.Builder()
                    .build())
            .setAndroidParameters(new DynamicLink.AndroidParameters.Builder()
                    .setMinimumVersion(3)
                    .build())
            .buildShortDynamicLink();

}

/*-----------------------------------------------------------------------------*/

private void share(String name, String deepLink) {

    String message = "Find "+name+" on SelfieLe - link: "+deepLink;
    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("text/plain");
    intent.putExtra(Intent.EXTRA_TEXT, message);
    startActivity(intent);
}

/*---------------------------------------------------------------------------------*/

String资源是 -

R.string.grp_post_link和R.string.dynamic_links_uri_prefix：

<string name="user_profile_link">https://testapp.com/user_profile?id=</string>
<string name="dynamic_links_uri_prefix">https://testapp.page.link</string>

在接收端，我们可以如下提取postId，groupKey等

  FirebaseDynamicLinks.getInstance().getDynamicLink(getIntent()).addOnSuccessListener(this, new OnSuccessListener<PendingDynamicLinkData>() {
        @Override
        public void onSuccess(PendingDynamicLinkData pendingDynamicLinkData) {

            if (pendingDynamicLinkData != null) {
                deepLink = pendingDynamicLinkData.getLink();
            }

            if (deepLink != null) {

               getGrpPost(deepLink.getQueryParameter("id"), deepLink.getQueryParameter("groupKey"),  deepLink.getQueryParameter("groupName"));


            }else {
                Toast.makeText(DynamicLinkActivity.this, "Can't find link", Toast.LENGTH_SHORT).show();
            }

        }
    }).addOnFailureListener(this, new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            Toast.makeText(DynamicLinkActivity.this, "Can't find link", Toast.LENGTH_SHORT).show();
        }
    });

getGroupPost（）;如下

 private void getGrpPost(String id, String groupKey, final String groupName) {
    //Do what you want
 }
