[DESCRIPTION]
MT6250 camcorder中在预览界面插拔耳机或其他的情况弹框背景为蓝色，需要在exit app screen函数中把base
layer清成黑色。
[SOLUTION]来自半导体社区
在mmi_camco_exit_app_screen函数中做如下修改：
static void mmi_camco_exit_app_screen(void) {
。。。
mmi_camco_set_base_layer(&g_mmi_camco_cntx.base_layer_handle, MMI_TRUE);
mmi_camco_osd_set_base_layer(g_mmi_camco_cntx.base_layer_handle);
gdi_layer_push_and_set_active(g_mmi_camco_cntx.base_layer_handle);
gdi_layer_clear(GDI_COLOR_BLACK);
gdi_layer_pop_and_restore_active();
//添加以下代码
gdi_layer_push_and_set_active(GDI_LAYER_MAIN_BASE_LAYER_HANDLE);
gdi_layer_clear(GDI_COLOR_BLACK);
gdi_layer_pop_and_restore_active();
//end
mmi_camco_osd_enter_state(MMI_CAMCO_OSD_STATE_EXIT);
mmi_camco_osd_reset_environment();
。。。
}
