This is a reland of commit 9fcaa034bc032da9de5d6fcdd45528169f44d343 Original change's description: > Remove jni_zero type aliases in jni_generator_helper.h. > > This CL removes some type alias from > sdk/android/src/jni/jni_generator_helper.h and make sure all the > jni_zero types are referred to using the jni_zero:: namespace. > > The goal is to remove sdk/android/src/jni/jni_generator_helper.h > in future CLs. > > Bug: b/319078685, b/351773023 > Change-Id: Ief60fce3e8f301f09ac5392d143aa5a82a445bcb > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/356882 > Reviewed-by: Zoé Lepaul <xalep@webrtc.org> > Reviewed-by: Jeremy Leconte <jleconte@google.com> > Commit-Queue: Mirko Bonadei <mbonadei@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#42618} Bug: b/319078685, b/351773023 Change-Id: I604b0842d220d76c36b73d2d49bcefe0ee7ae14f Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/356903 Commit-Queue: Jeremy Leconte <jleconte@google.com> Reviewed-by: Zoé Lepaul <xalep@webrtc.org> Cr-Commit-Position: refs/heads/main@{#42626}
