Apps Get Activity name from an application

[eatsleeplaxsoccer3]

Hi
I am trying to launch Google Voice when I double tap home.
I need to get the activity name to launch Google Voice. How can I get this?
To launch it, I need the full application name, which I have, com.google.android.apps.googlevoice but I also need the activity to start it up.
I have tried several guesses, but nothing has worked so far.
I just want it to start and open the main inbox ui
thanks

Im on my phone, so I cant really get into it right now, but google the concept of "reflection in Java."

i don't have an android developer kit set up on my machine, i just posted in the dev forum thinking one of y'all might know an easy way.
I'm looking at the classes.dex file but it's not that easy.
tried a java decompiler but didn't read .dex files

See if this helps you with your problem - Stack Overflow is usually really good with stuff like this.

android - Open another application from your own (intent) - Stack Overflow

thanks,
it looks like if i could run this code on an adroid phone with google voice installed, i could find the string I'm looking for
PackageManager pm = context.getPackageManager();
Intent appStartIntent = pm.getLaunchIntentForPackage("com.google.android.apps.googlevoice");
if (null != appStartIntent)
{
//get activity name from appStartIntent
}
however I don't have the capability of doing this


I've been going through the decompiled apk of google voice and trying to just find a startup activity.
the closest I've come is
com.google.android.apps.googlevoice/com.google.android.apps.googlevoice.activity.conversationlist.ConversationListActivity which launched it but only gave me a blank UI.

I got it!
So others know
for Google Voice, the startup activity is
com.google.android.apps.googlevoice.SplashActivity
so if you want google voice to open when you double tap home, modify the double tap entry in SQLLite to com.google.android.apps.googlevoice/com.google.android.apps.googlevoice.SplashActivity
if you need to find the startup activity for something in general, open up the androidmanifest.xml (open the .apk with winzip or something, you don't need a full decompiler)
and look for an activity with the category main or launcher
<activity android:theme="@style/TranslucentThemeNoActionBar" android:label="@string/app_icon_name" android:name=".SplashActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
