如何发送电报用一个意向 [英] How to send a Intent with telegram

问题描述

我想创建一个类在Java中，其管理的不同社交共享应用程序。类是基于在Android的意图。

I am trying to create a class in java which manages different social sharing apps. The class is based on android intents.

但是当我尝试执行电报的意图，它没有找到该应用程序。

but when I try to execute Telegram intent, it doesn't find the app.

下面我把code我写了：

Here I put the code I have written:

public void shareTelegram(String message)
{
            Intent waIntent = new Intent(Intent.ACTION_SEND);
            waIntent.setType("text/plain");
            waIntent.setPackage("com.telegram");
            if (waIntent != null) {
                waIntent.putExtra(Intent.EXTRA_TEXT, message);//
                _androidActivity.startActivity(Intent.createChooser(waIntent, "Share with"));
            } 
            else 
            {
                Toast.makeText(_androidActivity.getApplicationContext(), "Telegram is not installed", Toast.LENGTH_SHORT).show();
            }

}

去哪儿包的名称？ 先谢谢了。

Where could I find the package name? Thanks in advance.

推荐答案

所有的Andr​​oid应用程序有一个唯一的ID，市场ID。如果你到谷歌播放或谷歌搜索市场：//细节ID = org.telegram，它送你

All Android app have an unique ID, market ID. If you look into Google Play or google search market://details?id=org.telegram, It send you to

https://play.google.com/store/apps/details?id=org.telegram.messenger

如果您发送的意图有：

waIntent.setPackage("org.telegram.messenger");

这会工作。

如果您preFER一点点复杂的系统，我建议你使用：

If you prefer a little bit complex system I recommend you to use:

/**
     * Intent to send a telegram message
     * @param msg
     */
    void intentMessageTelegram(String msg)
    {
        final String appName = "org.telegram.messenger";
        final boolean isAppInstalled = isAppAvailable(mUIActivity.getApplicationContext(), appName);
        if (isAppInstalled) 
        {
            Intent myIntent = new Intent(Intent.ACTION_SEND);
            myIntent.setType("text/plain");
            myIntent.setPackage(appName);
            myIntent.putExtra(Intent.EXTRA_TEXT, msg);//
            mUIActivity.startActivity(Intent.createChooser(myIntent, "Share with"));
        } 
        else 
        {
            Toast.makeText(mUIActivity, "Telegram not Installed", Toast.LENGTH_SHORT).show();
        }
    }

和检查是否安装：

/**
         * Indicates whether the specified app ins installed and can used as an intent. This
         * method checks the package manager for installed packages that can
         * respond to an intent with the specified app. If no suitable package is
         * found, this method returns false.
         *
         * @param context The application's environment.
         * @param appName The name of the package you want to check
         *
         * @return True if app is installed
         */
        public static boolean isAppAvailable(Context context, String appName) 
        {
            PackageManager pm = context.getPackageManager();
            try 
            {
                pm.getPackageInfo(appName, PackageManager.GET_ACTIVITIES);
                return true;
            } 
            catch (NameNotFoundException e) 
            {
                return false;
            }
        }
