I'm trying to pass a PublicKey object from a service to an activity. However, the Aidl doesn't seem to support the PublicKey type. Any ideas on how to do this?

If you already have your public key you should put it into the /res/raw/ folder and retrieve it from there. Or store it in filesystem activity.getFilesDir().getAbsolutePath() would be your path. You can also use - pass Objects over IPC as described here in the article http://developer.android.com/guide/developing/tools/aidl.html hope this helps.

  • @Benner Thank you very much for you answer . in fact , I should have mentioned that the service and the activity does not belong to the same application , so I guess that your first suggestion does not apply in this case . I checked your link to the android developpers forum. I think i have to use the parcel and parcelable . But since i'm a newbie in android , i still don't get how to use them correctly , especially with the java PublicKey object . Thanks again. – user1118463 Jan 17 '12 at 12:25
  • you can save the Object into a byte array and set it to parcel then get it from there.
