不插T卡无法进入camera preview

由于没有预留手机空间，只有插入T卡时才可以进入camera preview，如果需要实现不插入T卡时可进行相机预览，只有当拍照时才提示插入T卡则可以参考以下修改方法： 
 
[SOLUTION] 
1 在函数mmi_camera_entry_app_pre_check（）中删除如下代码 
#if defined(__CAMERA_FEATURE_STORAGE__) 
 /*No phone storage*/ 
 if (SRV_FMGR_PUBLIC_DRV == SRV_FMGR_CARD_DRV || SRV_FMGR_PUBLIC_DRV == FS_DRIVE_NOT_FOUND) 
 { 
 /* only memory card but plugout, need show popup*/ 
 if (FS_NO_ERROR != FS_GetDevStatus(SRV_FMGR_CARD_DRV ,FS_MOUNT_STATE_ENUM)) 
 { 
 MMI_CAMERA_DISPLAY_POPUP((PU8)GetString(STR_GLOBAL_INSERT_MEMORY_CARD), MMI_EVENT_FAILURE,MMI_CAMERA_POPUP_RESULT_PROCESS_DELETE_GROUP); 
 return MMI_FALSE; 
 } 
 } 
#endif 
2 在函数mmi_camera_pre_init_app（）中删除如下代码： 
 /* check if path is valid or not. if not will pop up a screen after the preview screen is show */ 
 cur_storage = mmi_imgview_get_storage(); 
  
 if (mmi_camera_check_and_restore_valid_drv()) 
 { 
 /* drv is valid, create directory */ 
 mmi_imgview_get_storage_file_path(g_camera_cntx.storage_filepath); 
 create_result = mmi_imgview_create_file_dir(g_camera_cntx.storage_filepath); 
  
 /* create directory failed */ 
 if (create_result == FS_WRITE_PROTECTION) 
 { 
 g_camera_cntx.last_error = CAMERA_ERR_WRITE_PROTECT; 
 mmi_imgview_set_storage_not_ready(); 
 } 
 else if (create_result == FS_DISK_FULL) 
 { 
 g_camera_cntx.last_error = CAMERA_ERR_CARD_DISK_FULL; 
 mmi_imgview_set_storage_not_ready(); 
 } 
 else if (create_result == FS_ROOT_DIR_FULL)
 { 
 g_camera_cntx.last_error = CAMERA_ERR_ROOT_DIR_FULL; 
 mmi_imgview_set_storage_not_ready(); 
 } 
 else if (create_result == FS_INVALID_FILENAME) 
 { 
 g_camera_cntx.last_error = CAMERA_ERR_EXIST_PHOTOS_FILE; 
 mmi_imgview_set_storage_not_ready(); 
 } 
 else if (create_result == FS_INVALID_FILENAME) 
 { 
 g_camera_cntx.last_error = CAMERA_ERR_CREATE_DIR; 
 mmi_imgview_set_storage_not_ready(); 
 }  
 else 
 mmi_imgview_set_storage_ready(); 
 } 
 else 
 { 
 g_camera_cntx.last_error = MDI_RES_CAMERA_ERR_NO_DISK; 
 mmi_imgview_set_storage_not_ready(); 
 } 
3 在函数mmi_camera_entry_app_screen_internal（）中删除如下代码： 
 /*No phone storage*/ 
 if (SRV_FMGR_PUBLIC_DRV == SRV_FMGR_CARD_DRV || SRV_FMGR_PUBLIC_DRV == FS_DRIVE_NOT_FOUND) 
 { 
 /* only memory card but plugout, need show popup*/ 
 if (FS_NO_ERROR != FS_GetDevStatus(SRV_FMGR_CARD_DRV ,FS_MOUNT_STATE_ENUM)) 
 { 
 MMI_CAMERA_DISPLAY_POPUP((PU8)GetString(STR_GLOBAL_INSERT_MEMORY_CARD), MMI_EVENT_FAILURE,MMI_CAMERA_POPUP_RESULT_PROCESS_DELETE_GROUP); 
  
 return; 
 } 
 } 
4 在函数mmi_camera_capture_button_press（）的开始添加如下代码： 
#if defined(__CAMERA_FEATURE_STORAGE__) 
 /*No phone storage*/ 
 if (SRV_FMGR_PUBLIC_DRV == SRV_FMGR_CARD_DRV || SRV_FMGR_PUBLIC_DRV == FS_DRIVE_NOT_FOUND) 
 { 
 /* only memory card but plugout, need show popup*/ 
 if (FS_NO_ERROR != FS_GetDevStatus(SRV_FMGR_CARD_DRV ,FS_MOUNT_STATE_ENUM)) 
 { 
 MMI_CAMERA_DISPLAY_POPUP((PU8)GetString(STR_GLOBAL_INSERT_MEMORY_CARD), MMI_EVENT_FAILURE,MMI_CAMERA_POPUP_RESULT_PROCESS_DELETE_GROUP);   
 return;
 } 
 } 
#endif
