Up to Android P, there was this feature were we are able to define "requiredSystemPropertyValue" in the AndroidManifest.xml of the RRO apk, so that it will only be loaded if requiredSystemPropertyValue/requiredSystemPropertyName are matched. Porting support from idmap https://android.googlesource.com/platform/frameworks/base/+/master/cmds/idmap/scan.cpp#135 To idmap2 https://android.googlesource.com/platform/frameworks/base/+/master/cmds/idmap2/idmap2/Scan.cpp#175 Bug: 140891738 Change-Id: I47752af93efa4563a60e336c1e1b1ffc081b51ec
