This reverts commit 9fcaa034bc032da9de5d6fcdd45528169f44d343. Reason for revert: Breaks downstream project. 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: I003acf68e2b84bd0a5cda7c7180a28bcd3ca3772 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/356902 Owners-Override: Mirko Bonadei <mbonadei@webrtc.org> Commit-Queue: Mirko Bonadei <mbonadei@webrtc.org> Bot-Commit: rubber-stamper@appspot.gserviceaccount.com <rubber-stamper@appspot.gserviceaccount.com> Cr-Commit-Position: refs/heads/main@{#42619}
