Android 蓝牙权限
Android 11 及以下目标版本
https://developer.android.com/guide/topics/connectivity/bluetooth/permissions
-
BLUETOOTH：访问蓝牙适配器的权限，用于执行蓝牙操作。 -
BLUETOOTH_ADMIN：管理蓝牙适配器的权限，包括启用/禁用蓝牙、扫描设备和进行配对等操作。 -
ACCESS_FINE_LOCATION或ACCESS_COARSE_LOCATION：访问设备位置的权限。在 Android 6.0 及以上版本中，需要获取位置权限才能扫描附近的蓝牙设备。 -
ACCESS_BACKGROUND_LOCATION：在后台访问设备位置的权限。该权限通常在后台扫描蓝牙设备时使用。 -
需要手机开启定位服务
public boolean notNeedGps(Activity activity) { if (NullUtils.surviveActivity(activity)) { LocationManager manager = (LocationManager) activity.getSystemService(LOCATION_SERVICE); boolean isGPS = false; if (manager != null) { isGPS = manager.isProviderEnabled(LocationManager.GPS_PROVIDER); } if (!isGPS) { ConfirmDialog.Builder builder = new ConfirmDialog.Builder(activity); builder.setTitle(activity.getString(R.string.tip)) .setPositiveText("启用") .setContent("MeFengon需要启用手机定位服务\n否则手机导航和定位等功能将不可用") .setOnConfirmDialogClickListener(new ConfirmDialog.OnConfirmDialogClickListener() { @Override public void onPositiveClick() { Intent intent = new Intent(); intent.setAction(Settings.ACTION_LOCATION_SOURCE_SETTINGS); activity.startActivity(intent); } @Override public void onNegativeClick() { } }); builder.build().show(); } return isGPS; } else { return true; } }Android 12 中的新蓝牙权限

- 如果您的应用查找蓝牙设备（如蓝牙低功耗 (BLE) 外围设备），请向应用的清单中添加
BLUETOOTH_SCAN权限。 - 如果您的应用使当前设备可被其他蓝牙设备检测到，请向应用的清单中添加
BLUETOOTH_ADVERTISE权限。 - 如果您的应用与已配对的蓝牙设备通信，请向应用的清单中添加
BLUETOOTH_CONNECT权限。 - 对于旧版蓝牙相关的权限声明，请将
android:maxSdkVersion 设为 30。此应用兼容性步骤有助于系统仅向您的应用授予在搭载 Android 12 的设备上安装时所需的蓝牙权限。
