Capturing/Intercepting Android Intents during runtime

Question

Is there any way to capture/intercept Intents of application during runtime without modifying Android framework? Modifying Android framework might require too much work. Please help me.

Answer 1

To view Intents as they happen, run logcat in a shell and filter it down to just the Intents like this:

adb logcat | fgrep -i intent

(You can also add a filter for just your app's Intents, but that would exclude Intents sent to your app by the system and by other apps.)

This should show Intents such as

I/ActivityManager( 585): Starting activity: Intent { action=android.intent.action...}

To see system-wide Intents, try the Intent Intercept app.

To see all Intents sent to your own classes, then

• In each BroadcastReceiver, override onReceive(Context context, Intent intent).
• In each Activity, call getIntent() to get the Intent that started the activity.
• In each Service, override onStartCommand(Intent intent, int flags, int startId) to get the Intent that started the Service.

For info on all the standard Intent actions, see Intent.
