为什么在Android 10 OS中共享内容时未显示共享托盘标签的Intent LinkedIn图标

Question

我正在使用“共享”托盘通过意图共享来共享纯文本/文本，请从包装名称中读取软件包名称，并以标记的意图过滤应用。该列表中显示了某些应用程序，并且该列表中也包含了Linkedin软件包名称，但在共享托盘中未显示Linkedin图标。为什么未显示该图标？

我对您的代码进行了一些更改，以便通过Intent在LinkedIn上发帖。请检查下面给出的我的代码。我已经在android 10 os中进行了测试，并且工作正常。希望能帮助到你。

 private void shareTray(){
    Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
    sharingIntent.setType("text/plain");
    sharingIntent.putExtra(Intent.EXTRA_TEXT, sharedURL);

    Intent receiver=new Intent(getActivityContext, UserSelectedShareBroadcast.class);
    PendingIntent pendingIntent=PendingIntent.getBroadcast(getActivityContext, 0, receiver, PendingIntent.FLAG_UPDATE_CURRENT);

    PackageManager pm=getActivityContext.getPackageManager();
    Intent openInChooser=Intent.createChooser(sharingIntent, "Choose", pendingIntent.getIntentSender());
    List<ResolveInfo> resInfo=pm.queryIntentActivities(sharingIntent, 0);
    List<LabeledIntent> intentList=new ArrayList<>();

    Intent externalEmailIntent=new Intent(getActivityContext, ExternalEmailShareActivity.class);
            externalEmailIntent.putExtra("INBOX", "Inbox");
    intentList.add(new LabeledIntent(externalEmailIntent, "yourpackagename", "Email to", R.drawable.ic_mail_outline));

    for (int i=0; i < resInfo.size(); i++) {
        ResolveInfo ri=resInfo.get(i);
        String packageName=ri.activityInfo.packageName;
        if (packageName.contains("twitter")) {
            sharingIntent.setPackage(packageName);
        } else{
            if (packageName.contains("twitter") || packageName.contains("facebook") ||

                    shareIntent.setType("text/plain");
                    //shareIntent.setType("text/plain/image");
                    if (packageName.contains("twitter")) {
                        shareIntent.putExtra(Intent.EXTRA_TEXT, sharedURL);
                    } else if (packageName.contains("facebook")){shareIntent.putExtra(Intent.EXTRA_TEXT, sharedURL);
                    } else if (packageName.contains("whatsapp")) {
                        shareIntent.putExtra(Intent.EXTRA_TEXT, sharedURL);
                    } else if (packageName.contains("linkedin")) {

    }
    // convert intentList to array
    LabeledIntent[] extraIntents=intentList.toArray(new LabeledIntent[intentList.size()]);

    openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
    getActivityContext.startActivityForResult(openInChooser, REQUEST_SHARED_URL);

}
