安卓MTK屏蔽NavigationBar, 在SDK中通过搜索关键字修改，可适用大部分MTK及安卓版本．
方法介绍
- 搜索device/mediatek与device/mediateksample下的.xml把config_showNavigationBar值置为false
如下为搜索指令
find device/mediatek -name “*.xml” | xargs grep config_showNavigationBar
把true值改为false - 修改自己工程目录下的system.prop中qemu.hw.mainkeys=0为qemu.hw.mainkeys=1
如下为搜索指令
find device/mediatek -name “.prop" | xargs grep qemu.hw.mainkeys
find device/mediateksample/ -name ".prop” | xargs grep “qemu.hw.mainkeys”
这样可能会搜索到好几个文件，找到自己工程目录下的文件修改就行
SDK代码修改
如下为示例patch
