<!-- UTSJSON.UTSAndroid.getResourcePath.description -->

<!-- UTSJSON.UTSAndroid.getResourcePath.param -->

<!-- UTSJSON.UTSAndroid.getResourcePath.returnValue -->

<!-- UTSJSON.UTSAndroid.getResourcePath.compatibility -->

::: warning 注意事项

`getResourcePath` 与 [convert2AbsFullPath](https://doc.dcloud.net.cn/uni-app-x/uts/utsandroid.html#convert2absfullpath-path-string) 区别在于：

`getResourcePath` 屏蔽了读取`代码包文件`时 各平台/各模式下的底层细节，即使是存放在`asset`目录也会返回符合android 读取规范的协议地址，开发者只需要将返回路径当做普通文件读取即可。

`convert2AbsFullPath` 没有实现这一点。

当开发者需要读取`代码包文件`时，建议使用 `getResourcePath`


- [代码包文件](../api/file-system-spec.md#package)
  - `代码包文件`在`真机运行`和`云打包`模式下的释放策略不同：\
  	本地真机运行：会被存在放内置储存目录\
  	云打包： `uni-app x`项目会被存放在`asset`目录, `uni-app` 项目会被存放在内置储存目录\
  	因此 `uni-app`/`uni-app x` 平台对 `代码包文件` 均仅支持读取操作
- [本地磁盘文件](../api/file-system-spec.md#disk)
	- [沙盒文件](../api/file-system-spec.md#internalsandbox)
		- 不支持
	- [沙盒外文件](../api/file-system-spec.md#%E6%B2%99%E7%9B%92%E5%A4%96%E7%9B%AE%E5%BD%95)
		- 不支持

<!-- UTSJSON.UTSAndroid.rpx2px.param -->

<!-- UTSJSON.UTSAndroid.rpx2px.returnValue -->

<!-- UTSJSON.UTSAndroid.rpx2px.compatibility -->

### setPrivacyAgree(state:boolean):void;

### resetPrivacyAgree():void;

### requestSystemPermission()

<!-- UTSJSON.UTSAndroid.requestSystemPermission.description -->

<!-- UTSJSON.UTSAndroid.requestSystemPermission.param -->

<!-- UTSJSON.UTSAndroid.requestSystemPermission.returnValue -->

<!-- UTSJSON.UTSAndroid.requestSystemPermission.compatibility -->

```uts

	let permissionNeed = ["android.permission.CAMERA"]
    // 请求拍照权限
	UTSAndroid.requestSystemPermission(UTSAndroid.getUniActivity()!, permissionNeed, function (allRight : boolean, _ : string[]) {
		if (allRight) {
			// 权限请求成功
		} else {
			//用户拒绝了部分权限
		}
	}, function (_ : boolean, _ : string[]) {
		//用户拒绝了部分权限
	})

```

请求权限后有三种情况:

+ 用户允许了全部权限请求，会通过 `success`回调通知调用者，并且此时`allRight`参数为 `true`

+ 用户拒绝了全部权限请求，会通过 `fail` 回调通知调用者，`doNotAskAgain` 参数标识了用户拒绝时是否选择了`不再询问`

+ 用户允许了部分请求，拒绝了部分权限请求,此时既会调用`success`也会调用`fail`。由其中的 string数组参数 标识具体被拒绝/允许的权限


### checkSystemPermissionGranted()

}else{
	console.log("当前不具备指定权限")
}
```


### gotoSystemPermissionActivity()

    	console.log("当前已具备指定权限")
	}
```

### convert2AbsFullPath(path:string)

<!-- UTSJSON.UTSAndroid.convert2AbsFullPath.description -->

<!-- UTSJSON.UTSAndroid.convert2AbsFullPath.param -->

<!-- UTSJSON.UTSAndroid.convert2AbsFullPath.returnValue -->

<!-- UTSJSON.UTSAndroid.convert2AbsFullPath.compatibility -->


::: warning 注意事项

`convert2AbsFullPath` 与 [getResourcePath](https://doc.dcloud.net.cn/uni-app-x/uts/utsandroid.html#getresourcepath) 区别在于：

`convert2AbsFullPath` 对文件路径支持范围更大，不仅支持 `代码包文件`内置储存目录的情况，还支持相对路径，沙盒路径，沙盒外 系统API返回的文件地址等形式。

当开发者明确需要操作文件，而非代码包资源时，建议使用 `convert2AbsFullPath`


- [代码包文件](../api/file-system-spec.md#package)
  - `代码包文件`在`真机运行`和`云打包`模式下的释放策略不同：\
  	本地真机运行：会被存在放内置储存目录\
  	云打包： `uni-app x`项目会被存放在`asset`目录, `uni-app` 项目会被存放在内置储存目录\
  	因此在 `uni-app`/`uni-app x` 平台对 `代码包文件` 均仅支持读取操作
- [本地磁盘文件](../api/file-system-spec.md#disk)
	- [沙盒文件](../api/file-system-spec.md#internalsandbox)
		- `uni-app x`支持读写
		- `uni-app`不支持
	- [沙盒外文件](../api/file-system-spec.md#%E6%B2%99%E7%9B%92%E5%A4%96%E7%9B%AE%E5%BD%95)
		- 沙盒管理范围外的其他文件。 调用系统API返回的绝对地址属于此类。`uni-app`/`uni-app x`平台 均支持读写
		
:::

```ts
// 代码包文件
console.log(UTSAndroid.convert2AbsFullPath('static/logo.png'))
// 沙盒文件
console.log(UTSAndroid.convert2AbsFullPath('unifile://sandbox/static/logo.png'))
// 沙盒外文件
console.log(UTSAndroid.convert2AbsFullPath('/storage/emulated/0/Android/data/io.dcloud.HBuilder/apps/HBuilder/www/static/logo.png'))
