Google Maps v2 android crash when internet connection not available

Question

that showing google map API v2 with android. sometimes my app crash when no internet connection, like when i put GOOGLE Place API. when i clicked ATM and no internet then app will crash. i want to make a exception , so when no internet connection, then the map can show a notification that phone doest have a internet connection.

found soulution for this problem http://www.androidhive.info/2012/07/android-detect-internet-connection-status/

why don't you put some code that checks for internet activity once the app starts? [chech this link](http://stackoverflow.com/questions/4238921/android-detect-whether-there-is-an-internet-connection-available) — Taslim A. Khan, Sep 11 '13 at 17:49
alr used that code, but sometimes the internet not available, so apps will crash — kucluk, Sep 18 '13 at 11:19
did you check it with a device? what sort of internet connection are you using? on a device, if you are using a wifi connection, codes that were put earlier as answers will work, but if you are using data connection(mobile operator internet) then these codes might not work. Secondly, I have a feeling, but not sure, the codes available here does not work when you check for internet conectivity on an emulator. Please specify what type of connection you are checking. — Taslim A. Khan, Sep 18 '13 at 12:57

Try to Put this code:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (servicesOK()) {
        Toast.makeText(this, "Ready to map!", Toast.LENGTH_LONG).show();
        setContentView(R.layout.testmap);

    } else {
        setContentView(R.layout.activitymain);

    }


}

public boolean servicesOK() {

    int isAvailable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);

    if (isAvailable == ConnectionResult.SUCCESS) {

        return true;

    } else if (GooglePlayServicesUtil.isUserRecoverableError(isAvailable)) {

        Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable,
                this, GPS_ERRORDIALOG_REQUEST);
        dialog.show();

    } else {

        Toast.makeText(this, "Can not connect!", Toast.LENGTH_SHORT).show();

    }
    return false;
}

This might help you..:)

Hi Mike i still cannot resolved that problem, would you mind to check the code here http://wptrafficanalyzer.in/blog/showing-nearby-places-using-google-places-api-and-google-map-android-api-v2/ and how when no internet connections and users click FIND button. – kucluk Sep 18 '13 at 11:20
Hi mike this is mainactivity code and JSON parser http://pastebin.com/hkQSwEHE this JSON Parser http://pastebin.com/v7MabBdc – kucluk Sep 18 '13 at 15:31
Hey..Thanks for the info.. Did you check with the Manifest ? are all the permissions in place ? Most importantly, the internet permission ? – mike20132013 Sep 18 '13 at 17:12
Hi mike its not about manifest. its about how to make a exception or Try catch, so when no internet connection the apps will not crash – kucluk Sep 19 '13 at 06:08

You can use this method to check if there is an internet connection on the device:

public boolean isNetworkAvailable() {
    ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager
            .getActiveNetworkInfo();
    return activeNetworkInfo != null;
}

use an if statement to handle the crash.

    public boolean isNetworkAvailable() {
        ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager
                .getActiveNetworkInfo();
        return activeNetworkInfo != null;
    }

if (isNetworkAvailable == true){
//your map code
} else {
Log.e("Error","No network");
 Toast.makeText(this, "no internet" , Toast.LENGTH_LONG).show();
 }
}

don't forget to have checking the network permission in your manifest.

*the method is taken from Emmanuel's answer

i mean when parsing from JSON when no internet, everytime no internet my map will crash. — kucluk, Sep 15 '13 at 19:31
