# 高级操作

可能造成一些未知问题，请谨慎操作。

## 无障碍高级版

系统无障碍（辅助）功能分为基础版和高级版，当前版本所有功能都在基础版中。

* ![7.1](/files/-M2wcL-ZJDPSVDRfYaHr)高级版具有一些新开发的手势功能（如微信对话取词，长截图滚屏，录制动作时使用手势等）。
* 如果高级版遇到性能问题如严重掉帧等（系统Bug），可以切换到基础版。

## ADB 权限提升

使用 ADB 命令提升 fooView 在手机上的权限。\
请在PC端使用 ADB 来执行以下命令，手机端执行时请删除 adb shell 前缀。

### 辅助功能防被杀

```
提升:adb shell pm grant com.fooview.android.fooview android.permission.WRITE_SECURE_SETTINGS
恢复:adb shell pm revoke com.fooview.android.fooview android.permission.WRITE_SECURE_SETTINGS
```

### 监听剪贴板

![Q](/files/-M2wcTJRWVZUo7k0rXGA)因系统限制，需提权以监听系统剪贴板，否则无法使用相关功能。

```
adb -d shell pm grant com.fooview.android.fooview android.permission.READ_LOGS
```

## 备份信息

fooView 除了设置以外的信息都存储在 `Android/data/com.fooview.android.fooview` 目录中。

新版本备份的设置目录结构有变化,如果在旧版本需要使用新版本的备份,需要手动解压压缩包到卡上`.fooView`。

设置备份可通过自带功能实现（保存在 `fooViewSave`）。

## 日志记录

当你的fooView无响应乃至崩溃时，请进入全局搜索，在搜索栏输入代码并回车。

```
开启:fvconfig.log.on
关闭:fvconfig.log.off
```

开启成功后请重新操作一遍出现问题的过程，让其记录到日志中。 记录成功后会在根目录生成文件fv\_log.txt，将其发送给官方即可。 然后可输入第二条off关闭日志记录。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://sealt.gitbook.io/fooview/gao-ji-cao-zuo.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
