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
https://developer.android.google.cn/about/versions/12/features/bluetooth-permissions?hl=zh-cn
- 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。
