What does `act` and `cat` mean in ActivityManager in Android?
When I capture adb logcat in an Android application. I see below log:
ActivityManager: START u0 {act=android.intent.action.VIEW cat=[android.intent.category.BROWSABLE]
I don't understand what act and cat mean in the above log. Does them relate to ActivityManager? I couldn't find any clue in the doc.

act means action, and cat means category.
Here's a snippet of what Intent.toString does:
public void toShortString(StringBuilder b, boolean secure, boolean comp, boolean extras,
boolean clip) {
boolean first = true;
if (mAction != null)
b.append("act=").append(mAction); // Action
first = false;
if (mCategories != null)
if (!first)
b.append(' ');
first = false;
b.append("cat=["); // Categories
for (int i=0; i<mCategories.size(); i++)
if (i > 0) b.append(',');
b.append(mCategories.valueAt(i));
b.append("]");
// ...
The reason why you're seeing this in the log is very likely because of the intent has been dispatched by one of the apps or services, so the system can decide which apps to handle the intent with specific action and categories.

It means an intent has been dispatched to view something and has a category of browsable to the system, and whichever of the app can support this intent will handle it.
