Question

I have two Activities in my Android app that deal with NFC. One has a declared IntentFilter in the AndroidManifest.xml, while the other just accepts NFC actions while it is active using a PendingIntent and onNewIntent();. However, sometimes when in the latter activity I actually want to pass the NFC action on the the former. How do I “release” the Intent to a different activity without losing any of the NFC information within?

Answer 1

Use startActivity(Intent intent) but instead of the Intent being created using the specific MyActivity.class form (an explicit Intent), add the action/category that the first Activity is set to react to in its manifest <intent-filter> section (an implicit Intent).
