问题
I'm getting the following exception during an ACTION_SEND intent with a data type application/pdf:
java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.SEND typ=application/pdf flg=0x3080000 cmp=com.adobe.reader/.ARSendForSignature (has extras) }
This brings up a dialog to choose the desired application to receive the PDF. I believe the SecurityException is being thrown when a user chooses Adobe Reader from the list, although it appears to be opening specifically the ARSendForSignature activity.
Any ideas?
回答1:
You are encountering a bug in the Adobe Reader app, or a bug in Android, depending upon your perspective.
The Adobe Reader ARSendForSignature activity supports the ACTION_SEND <intent-filter>, but they explicitly have android:exported="false", which denies anyone but them the ability to start that activity.
Either:
- Adobe Reader should not have that
<intent-filter>, or - Adobe Reader should not have marked it as not exported, or
- The Android chooser should filter out non-exported activities
Long-term, the answer should be #3 -- I'll work on reproducing this problem and will file an issue, assuming there isn't already one. Short-term, Adobe can fix this faster than we can fix a couple hundred million devices. :-)
