通过apktool工具反编译talk.apk的AndroidManifest.xml文件，可以知道talk是通过类SigningInActivity进行google用户的登入，那么要自己写的程序调用已经安装了talk程序的过程只需如下操作

Intent mIntent = new Intent();

mIntent.setAction("android.intent.action.MAIN");

mIntent.addCategory("android.intent.category.DEFAULT");

mIntent.addCategory("android.intent.category.LAUNCHER");

mIntent.addCategory("android.intent.category.VOICE_LAUNCH");

startActivity(mIntent);
