Subject: [PATCH] Do not send new Intent to non-exported activity when
|
|
navigateUpTo
|
|
|
|
The new Intent was delivered to a non-exported activity while
|
|
'#navigateUpTo was called from an Activity of a different uid.
|
|
|
|
Backport to pie:
|
|
* services/core/java/com/android/server/am directory (not wm)
|
|
* back port of getPid() method
|
|
|
|

Test: atest StartActivityTests
