Subject: [PATCH] Add removeInstanceForPackageMethod to SensorManager
|
|
|
|
In order to ensure that clients don't leak their sensor manager
|
|
instance that we currently store in a static map, they need to be able
|
|
to remove their instance. Otherwise, this instance is never removed from
|
|
the list and will hang around until our SensorManage instance is
|
|
destroyed.
|
|
|
|
Bug: 269014004
|
|
Test: Run ./libsensorserviceaidl_fuzzer
