How to launch Telegram app from my own android application?
提问by BoshRa
I have an android app that should be able to open a chat in the telegram app by pressing a button.
I want to open an existing robot chat page DIRECTLY from my app. I have a valid token for my robot. How can this be achieved?
我有一个 android 应用程序，它应该能够通过按下按钮在电报应用程序中打开聊天。
我想直接从我的应用程序打开一个现有的机器人聊天页面。我的机器人有一个有效的令牌。如何做到这一点？
Thanks in advance.
提前致谢。
robot name : @InfotechAvl_bot
机器人名称：@InfotechAvl_bot
robot token: 179284***********
机器人令牌：179284***********
//-------------
case ContentFragment.lMenuTelegram:
Intent LaunchIntent=getPackageManager().getLaunchIntentForPackage("org.telegram.messenger");
startActivity(LaunchIntent);
break;

If you prefer a little bit complex system I recommend you to use:
如果您喜欢稍微复杂的系统，我建议您使用：
/**
* 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();
}
}
And check if is installed with:
并检查是否安装了：
/**
* 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;
}
}
Hope this works for you.
希望这对你有用。
