MTK Android 14 通过属性控制系统设置显示双栏或者单栏

第一步确认有添加静态库

--- a/system_mssi_u0/vendor/mediatek/proprietary/packages/apps/MtkSettings/Android.bp
+++ b/system_mssi_u0/vendor/mediatek/proprietary/packages/apps/MtkSettings/Android.bp

第二步 验证
system_mssi_u0\vendor\mediatek\proprietary\packages\apps\MtkSettings\src\com\android\settings\activityembedding\ActivitvEmbeddingUtils.java 中isEmbeddingActivityEnabled 方法
返回值 true 时显示设置显示双栏

第三步修改源码

+    Log.d(TAG, "yim test isEmbeddingActivityEnabled = " + isSupportSettingsSplitEnabled);
+
+    return isSupportSettingsSplitEnabled;
+       }

在合适的地方配置 ro.product.is support SettingsSplitEnabled 即可。
