my app is crashing when there is no internet and i want my markers or my map to refresh each second

i made a googlemap app where my markers are displyed.
the problem is when there no internet, the app is crashing. The code under onResume does not solve the problem.
also i want to refresh the map or markers each second on the map.
if you have any ideas please i am here to learn from all of you.
here is my MapActivity code :

this MapActivity is slow to load, could you teach me a way to make it goes faster?
Best regard :)
waiting for your propositions.
PS: i have removed some functions to make the code look short but i kept the most important in is case.

For the crashing issue
create a class
public class NetWorkChecker {
static NetworkInfo wifi, mobile;
public static Boolean check(Context c) {
ConnectivityManager cm = (ConnectivityManager) c.getSystemService(Context.CONNECTIVITY_SERVICE);
try {
wifi = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
mobile = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
} catch (Exception e) {
e.printStackTrace();
}
if (wifi != null && wifi.isConnected() && wifi.isAvailable()) {
return true;
} else if (mobile != null && mobile.isAvailable() && mobile.isConnected()) {
return true;
} else {
//Toast.makeText(c, "No Network Connection", Toast.LENGTH_SHORT).show();
// ((Activity) c).finish();
displayMobileDataSettingsDialog(c,"No Network Connection","No Network Connection");
return false;
}
}
public static AlertDialog displayMobileDataSettingsDialog(final Context context, String title, String message) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(title);
builder.setMessage(message);
builder.setCancelable(false);
builder.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Settings.ACTION_DATA_ROAMING_SETTINGS);
context.startActivity(intent);
}
});
builder.show();
return builder.create();
}
}
to check if the devise have an active internet connection
call
if (!NetWorkChecker.check(this)){
////do your refres
}

Android app unexpected going back to previous activity

I added my application to Github to find my bug.
So the bug is like when I open my app for a first time and open "info" then "settings" and click thought all options, then "new measurement" then it goes to previous screen (settings) instead of new measurement. Could anybody help me?
Here is the link to app
Edit:
Here are probably the meaningfull classes:

Why does my Java code for Android App Generate 2 threads?

I am new to Java coding for android. I need to understand why does my code generate 2 threads. The problem that can be created over here is perhaps competition for Camera Resources which results in the camera not being used by the user. Kindly suggest a solution to my problem as well.
I have also attached a picture where there are 2 requests for a new activity. There is also proof by having 2 thread IDs active.
EDIT for clarity:
I want to generate a new thread which solely handles the activity to record the video, no other thread should be doing it. But there are two that are performing their own activity to record video.
public class MainActivity extends AppCompatActivity implements SensorEventListener/*, ActivityCompat.OnRequestPermissionsResultCallback*/ {

Every time you tap on TextView, as you are using onTouchListener, it will be fired twice, once for ACTION_DOWN and ACTION_UP, so check for ACTION_UP as in

Custom Icon on Android Google maps not loading

Ill try my best to explain.
I have a page on my android app that is a google map that has stores locations on it.
Depending on the type of store, it has a custom icon. The link for the custom icon I retrieved trough MySQL.
The problem I am having is when I open the page instead of showing me the custom icons for the stores it shows me the default icon. But when I go to another page on the app and go back to the maps page it loads all the custom icons. It seems to me that on the first page launch it does not replace the default icon.
Since im new to programming ive added the whole page because I might be missing something. I think that the reason this is happening is due to the method "parseData()"
Thank you,

Check this documentation on how to customize the marker image.
You can replace the default marker image with a custom marker image, often called an icon. Custom icons are always set as a BitmapDescriptor, and defined using one of the methods in the BitmapDescriptorFactory class.
Here is a sample code on how to create a marker with a custom icon.
private static final LatLng MELBOURNE = new LatLng(-37.813, 144.962);
private Marker melbourne = mMap.addMarker(new MarkerOptions()
.position(MELBOURNE)
.title("Melbourne")
.snippet("Population: 4,137,400")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));
NOTE:
getMap() is already deprecated, so use getMapAsync() in your code.

How can I send the "SCAN_RESULT" to another activity with zxing in eclipse

How can I put the result of the QR "SCAN_RESULT" in different activity, this is my problem.
In the splash screen I need to go to the QRScanner (CaptureActivity), and then, to the ActivityQR who will send the info. to the SQLite.
The problem is: When I get de QRCode in string ("SCAN_RESULT") on "CaptureActivity.java", the app close because the app need "back" to the previous activity with this:
getIntent();
I try to modify this codeline, but this not solve my problem.
How can I put the "SCAN_RESULT" in the ActivityQR? I don't know how open other activity (this case ActivityQR) when the code had gottenm and put this String value on the ActivityQR
I Use "CaptureActivity" of ZXing (ZebraCrossing)
Thanks in advance.

your SplashScreen Java should look like this:
{
Intent mainIntent = new Intent().setClass(SplashScreenActivity.this, com.google.zxing.client.android.CaptureActivity.class);
// use startActivityForResult instead of startActivity
startActivityForResult(mainIntent)
}
but I guess you already solved you problem!
