我正在尝试从我的Android应用程序中向特定号码发送电报消息.现在我的代码启动Telegram应用程序,然后用户必须选择destinatary.我想要做的是将消息发送到指定的号码,而无需用户选择联系人.我的代码如下:

/**
 * 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();
    }
}
