android – 检查Internet连接是否可用？

我正在开发在线应用程序. [问题]当互联网停机或不可用时,它给我错误[强制关闭],我试图使用broadCast接收器处理但不满足精确解决方案,寻找更好的解决方案.

public class MyBroadcastReceiver extends BroadcastReceiver {
 
@Override
public void onReceive(final Context context,final Intent intent) {
 
    NetworkInfo info = intent
            .getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);
 
    if (null != info) {
 
        String state = info.getState().toString();
 
        if (state.equalsIgnoreCase("CONNECTED")) {
            SplashScreen.isWiFiConnected = true;
            Log.i("isWifiConnected","=================TRUE");
        } else {
            SplashScreen.isWiFiConnected = false;
            Log.i("isWifiConnected","=================FALSE");
        }
 
    }
 
}
 
}

谢谢.

解决方法

static String data = null;
private static HttpPost httppost;
private static HttpParams httpParameters;
private static int timeoutConnection = 30000;
private static HttpClient httpclient = null;
private static HttpResponse response = null;
private static int responseCode=0;
public static ConnectivityManager mConnectivityManager;
public static NetworkInfo mNetworkInfo;
public static boolean isNetError=false;
 
/** Post Http data and returns final string and status on network */
 
public static void postHttp(String Url,Activity mActivity) {
try {
    isNetError=false;
 
    mConnectivityManager= (ConnectivityManager) mActivity.getSystemService(Context.CONNECTIVITY_SERVICE);
    mNetworkInfo = mConnectivityManager.getActiveNetworkInfo();
 
    if (mNetworkInfo != null && mNetworkInfo.isConnectedOrConnecting())
    {
        httppost = new HttpPost(Url);
        httpParameters = new BasicHttpParams();
        HttpConnectionParams.setSoTimeout(httpParameters,timeoutConnection);
        httpclient = new DefaultHttpClient(httpParameters);
 
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("text","some Text"));
 
 
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,HTTP.UTF_8));
 
        // Execute HTTP Post Request
        response = httpclient.execute(httppost);
        data = EntityUtils.toString(response.getEntity());
 
    }
    else
        isNetError=true;
 
    } catch (Exception e) {
        e.printStackTrace();
        isNetError=true;
        }
 
   if (responseCode == 200)
   {
        isNetError=false;
        System.out.println("final..." + data);
        }
        else
            isNetError=true;
    }

在asyntask的doInBackground()中调用此方法,并在onPostExecute()中检查isNetError值,并在添加权限的其他答案中提及< uses-permission android：name =“android.permission.ACCESS_NETWORK_STATE”/>

if(isNetError)
//No internet 
else
//do your stuff
