Hi,all, thanks for the discussions and great feedback. I think, I am a bit confused about this discussion. What I want: 1) get the Intent without running the app ; 2) get the Intent without decompiling the Android app. 3) I just want the major Intents to invokes the deputy apps , e.g., Email, Browser, Camera, SMS What is the best location should I look for them in Andorid?

3) I just want the major Intents to invokes the deputy apps , e.g., Email, Browser, Camera, SMS What is a deputy app? What is a major Intent? Let me try to project what he wants: a list of the intent filters, as they would come from the manifest. Question: why do you want this? The only reason to have this is because you're sending generated strings to apps to coerce them to do bad things. What you want to know is if some intent is available, for that you can use the package manager, which is a much more sensible thing to do. http://developer.android.com/reference/android/content/pm/PackageManager.html#queryIntentActivities(android.content.Intent, int) I.e., there is no use in knowing a complete list of available intents, other than trying to attack the things on the device. However, if you have a specific intent in mind, and want to find someone who will respond to it, you can find out through the package manager. And I would guess by major intents, he means preinstalled apps, or something like that... kris -- You received this message because you are subscribed to the Google Groups Android Developers group.
