From 733a0ea4064a4bae50d0716b6331a3a98e18def9 Mon Sep 17 00:00:00 2001 From: Yohei Yukawa Date: Sun, 24 Jun 2018 15:52:36 -0700 Subject: Merge inputmethodcommon into LatinIME repo This is a preparation to deprecate frameworks/opt/inputmethodcommon repository. Currently repository 'inputmethodcommon' is used only from LatinIME. Having such a repository only for one project is overkill. Also, to add gradle build support to LatinIME project, it would be much easier LatinIME didn't have such a dependency. This CL mechanically copies files in 'inputmethodcommon' repository to 'LatinIME' repository. In theory there should be no behavior change. Bug: 110741521 Test: tapas LatinIME && make -j Change-Id: I3fabb038be9a944dcd9ef79ffcc89800a5f0bf5a --- .../inputmethodcommon/InputMethodSettingsImpl.java | 179 +++++++++++++++++++++ 1 file changed, 179 insertions(+) create mode 100644 java/src/com/android/inputmethodcommon/InputMethodSettingsImpl.java (limited to 'java/src/com/android/inputmethodcommon/InputMethodSettingsImpl.java') diff --git a/java/src/com/android/inputmethodcommon/InputMethodSettingsImpl.java b/java/src/com/android/inputmethodcommon/InputMethodSettingsImpl.java new file mode 100644 index 000000000..cfa1a6596 --- /dev/null +++ b/java/src/com/android/inputmethodcommon/InputMethodSettingsImpl.java @@ -0,0 +1,179 @@ +/* + * Copyright (C) 2011 The Android Open Source Project + * + * Licensed under the Apache License, Version 2.0 (the "License");
