AndroidTV获取U盘路径使用广播法和遍历法获取机顶盒的U盘绝对路径阅读详情

AI摘要

该博客围绕Android获取U盘路径展开。首先提到权限问题，接着介绍通过storemanager获取usb路径的方法，还涉及监听U盘状态，为在Android系统中处理U盘相关操作提供了关键信息。

1. 权限

<uses-permission android:name="android.permission.USB_PERMISSION" />

2. 通过storemanager获取usb 路径

 val storageManager = getSystemService(STORAGE_SERVICE) as StorageManager
            val volumes = storageManager.storageVolumes
            for (volume in volumes) {
                val path = volume.directory!!.path
                if (volume.isRemovable) {
                    mainViewModel.usbStorage = path
                }
            }

3. 监听u盘状态

 private fun registerUsbReceiver() {
        val filter = IntentFilter()
        filter.addAction(Intent.ACTION_MEDIA_MOUNTED)
        filter.addAction(Intent.ACTION_MEDIA_UNMOUNTED)
        filter.addAction(Intent.ACTION_MEDIA_BAD_REMOVAL)
        filter.addDataScheme("file")
        registerReceiver(usbReceiver, filter)
    }

 //默认U盘安装地址
    private val usbReceiver: BroadcastReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context, intent: Intent) {
            val action = intent.action
            if (action == Intent.ACTION_MEDIA_MOUNTED) {
                mainViewModel.usbStorage = intent.data!!.path
                Log.d("MainActivity", "usbReceiver ${mainViewModel.usbStorage}")
            }
        }
    }
