Android 8.1 删除Launcher桌面搜索框

最近接到项目反馈，要求删除Launcher桌面的搜索框，具体修改参照如下：

/vendor/mediatek/proprietary/packages/apps/Launcher3/src/com/android/launcher3/config/BaseFlags.java

+    public static final boolean QSB_ON_FIRST_SCREEN = false;
-    public static final boolean QSB_ON_FIRST_SCREEN = true;

+    public static final boolean QSB_IN_HOTSEAT = false;
-    public static final boolean QSB_IN_HOTSEAT = true;

/vendor/mediatek/proprietary/packages/apps/Launcher3/src/com/android/launcher3/provider/ImportDataTask.java

    private void importWorkspaceItems(
            long firsetScreenId, LongSparseArray<Long> screenIdMap) throws Exception {
        String profileId = Long.toString(UserManagerCompat.getInstance(mContext)
                .getSerialNumberForUser(Process.myUserHandle()));

        boolean createEmptyRowOnFirstScreen;
        if (FeatureFlags.QSB_ON_FIRST_SCREEN) {
            try (Cursor c = mContext.getContentResolver().query(mOtherFavoritesUri, null,
                    // get items on the first row of the first screen
                    "profileId = ? AND container = -100 AND screen = ? AND cellY = 0",
                    new String[]{profileId, Long.toString(firsetScreenId)},
                    null)) {
                // First row of first screen is not empty
                createEmptyRowOnFirstScreen = c.moveToNext();
            }
+        } else {
+            createEmptyRowOnFirstScreen = false;
        }

重新编译验证，修改生效，Launcher桌面的搜索框已删除
