My application activity is having a block of code which I want to check the connected network having active connection before accessing FireBase Auth Login.
I created a class for networkState add a block of code for checking networkActiveConnection
private void networkState() throws IOException {
final ConnectivityManager conMgr = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
assert conMgr != null;
final NetworkInfo activeNetwork = conMgr.getActiveNetworkInfo();
if (activeNetwork != null && activeNetwork.isConnectedOrConnecting()) {
Toast.makeText(getApplicationContext(),"Network connected",Toast.LENGTH_SHORT).show();
//checking active internet service
HttpURLConnection urlc = (HttpURLConnection)(new URL("http://www.google.com").openConnection());
urlc.setRequestProperty("User-Agent", "Test");
urlc.setRequestProperty("Connection", "close");
urlc.setConnectTimeout(10000);
urlc.connect();
if(urlc.getResponseCode() == 200){
Toast.makeText(getApplicationContext(), "Network has active internet", Toast.LENGTH_SHORT).show();
//user login
signInUser();
}else {
Toast.makeText(getApplicationContext(), "No active internet connection", Toast.LENGTH_SHORT).show();
}
//end of checking active internet service
} else {
Toast.makeText(getApplicationContext(),"Network not connected",Toast.LENGTH_SHORT).show();
}
}
Application keeps crashing. I cant move without the solution.Where I missed? Is there any other method to check the connected network having active connection?
Finally I found an answer.Its actually happening due to the version. Up to Android 3.0 and above all long process activities will work at only AsyncTask
I restructured the actual internet connection in the device by load checking of Google.com. I don't know what it will happen when google.com is down.
The following code may help.
@SuppressLint("StaticFieldLeak")
public class activeConnection extends AsyncTask<Void, Void, Boolean> {
@Override
protected Boolean doInBackground(Void... params) {
try {
URL url = new URL("http://www.google.com");
HttpURLConnection urlc = (HttpURLConnection) url.openConnection();
urlc.setConnectTimeout(3000);
urlc.connect();
if (urlc.getResponseCode() == 200) {
return true;
}
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
return false;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
}
return false;
}
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR1)
@Override
protected void onPostExecute(Boolean result) {
if (!result) { // code if not connected
AlertDialog.Builder builder = new AlertDialog.Builder(Customers.this, R.style.MyDialogTheme);
builder.setTitle("ALERT");
builder.setMessage("Activate your Internet connection and Try again");
builder.setCancelable(false);
builder.setPositiveButton(
"Retry",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
new activeConnection().execute();
}
});
AlertDialog alert11 = builder.create();
alert11.show();
} else { // code if connected
}
}
}
