Android获取WIFI 的ssid 方法适配Android9.0

废话不多说了直接上代码
首先在Androidmanifast 中添加权限
## 获取SSID 的方法如下/** * 获取SSID * @param activity 上下文 * @return WIFI 的SSID */ public String getWIFISSID(Activity activity) { String ssid="unknown id"; if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.O||Build.VERSION.SDK_INT==Build.VERSION_CODES.P) { WifiManager mWifiManager = (WifiManager) activity.getApplicationContext().getSystemService(Context.WIFI_SERVICE); assert mWifiManager != null; WifiInfo info = mWifiManager.getConnectionInfo(); if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) { return info.getSSID(); } else { return info.getSSID().replace("\"", ""); } } else if (Build.VERSION.SDK_INT==Build.VERSION_CODES.O_MR1){ ConnectivityManager connManager = (ConnectivityManager) activity.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE); assert connManager != null; NetworkInfo networkInfo = connManager.getActiveNetworkInfo(); if (networkInfo.isConnected()) { if (networkInfo.getExtraInfo()!=null){ return networkInfo.getExtraInfo().replace("\"",""); } } } return ssid; }MainActivity方法。布局文件太简单了 。不贴代码了
public class MainActivity extends AppCompatActivity { private PermissionHelper permissionHelper; TextView mTvSSID; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTvSSID = findViewById(R.id.tvSSID); Toolbar toolbar = findViewById(R.id.toolbar); setSupportActionBar(toolbar); permissionHelper = new PermissionHelper(this); getWifiSSid(); } private void getWifiSSid() { permissionHelper.check(Manifest.permission.ACCESS_FINE_LOCATION).onSuccess(this::onSuccess).onDenied(this::onDenied).onNeverAskAgain(this::onNeverAskAgain).run(); } private void onSuccess() { mTvSSID.setText(DeviceUtil.INSTANCE.getWIFISSID(this)); } private void onDenied() { ToastUtil.INSTANCE.show(this, "权限被拒绝，9.0系统无法获取SSID"); } private void onNeverAskAgain() { ToastUtil.INSTANCE.show(this, "权限被拒绝，9.0系统无法获取SSID,下次不会在询问了"); } @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { permissionHelper.onRequestPermissionsResult(requestCode, permissions, grantResults); }}Android8.1获取方法
需要在Androidmanifast.xml文件中添加如下权限
ConnectivityManager connManager = (ConnectivityManager) activity.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE); assert connManager != null; NetworkInfo networkInfo = connManager.getActiveNetworkInfo(); if (networkInfo.isConnected()) { if (networkInfo.getExtraInfo()!=null){ return networkInfo.getExtraInfo().replace("\"",""); } }9.0 以后需要申请运行时权限
在Androidmanifast.xml文件中添加
权限申请框架
在model 中的gradle中加入以下依赖。
