藍(lán)牙的權(quán)限

這里我們只簡(jiǎn)單的聊下藍(lán)牙的掃描和連接，不牽扯到使用藍(lán)牙掃描結(jié)果來(lái)推到物理位置

1. 聲明權(quán)限

>= Android 12

BLUETOOTH_SCAN
BLUETOOTH_CONNECT

這兩個(gè)權(quán)限都是運(yùn)行時(shí)權(quán)限

<= Android 11

BLUETOOTH

ACCESS_FINE_LOCATION

位置權(quán)限屬于運(yùn)行時(shí)權(quán)限

2. 示例代碼

fun requestPermissions(onSuccess: () -> Unit) {
    this.onSuccessCallback = onSuccess

    val missingPermissions = mutableListOf<String>()

    // >= Android 12
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
        // 掃描權(quán)限
        if (ContextCompat.checkSelfPermission(fragment.requireContext(), Manifest.permission.BLUETOOTH_SCAN) != PackageManager.PERMISSION_GRANTED) {
            missingPermissions.add(Manifest.permission.BLUETOOTH_SCAN)
        }

        // 連接權(quán)限
        if (ContextCompat.checkSelfPermission(fragment.requireContext(), Manifest.permission.BLUETOOTH_CONNECT) != PackageManager.PERMISSION_GRANTED) {
            missingPermissions.add(Manifest.permission.BLUETOOTH_CONNECT)
        }
    } else // >= Android 6.0
        // 位置權(quán)限
        if (ContextCompat.checkSelfPermission(fragment.requireContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            missingPermissions.add(Manifest.permission.ACCESS_FINE_LOCATION)
        }

    if (missingPermissions.isNotEmpty()) {
        permissionLauncher.launch(missingPermissions.toTypedArray())
    } else {
        checkBluetoothSwitch()
    }

}
