I found that application crashes without logcat entries due to some Native crash. As in Android Studio 2.3.3 the logcat has both Verbose and No filters options are set by default:
Well what are the ways of solving native crashes or identify these crashes?
My application is crashing on opening MapsActivity more than two times i.e on third(edit : now fourth) click to open brings it to crash.
Here is my MapsActivity it receives Location List from the MainActivity and adds markers to the Map on those locations.
import android.content.pm.ActivityInfo;
import android.content.pm.PackageManager;
import android.location.Location;
import android.support.v4.app.ActivityCompat;
import android.support.v4.app.FragmentActivity;

import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
import java.lang.reflect.Type;
import java.util.ArrayList;
import java.util.List;
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
ArrayList<Location> locs = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
Bundle bundle = getIntent().getExtras();
String jsonString = bundle.getString("KEY_LOCATIONS");
Gson gson = new Gson();
Type listOfLocationType = new TypeToken<List<Location>>() {
}.getType();
locs = gson.fromJson(jsonString, listOfLocationType);
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
setUpMap();
}
public void setUpMap() {
mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;}
mMap.setMyLocationEnabled(true);
mMap.getUiSettings().setMyLocationButtonEnabled(true);
mMap.getUiSettings().setCompassEnabled(true);
addMarkeratLocation();
}
public void addMarkeratLocation() {
int i;
double lt=0.0,lg=0.0;
BitmapDescriptor icon = BitmapDescriptorFactory.fromResource(R.mipmap.dottt);
LatLng addpoint = new LatLng(0.0, 0.0);
for (i = 0; i < locs.size(); i++) {
lt=locs.get(i).getLatitude();
lg=locs.get(i).getLongitude();
addpoint = new LatLng(lt,lg );
mMap.addMarker(new MarkerOptions().position(addpoint).icon(icon));
}
mMap.moveCamera(CameraUpdateFactory.newLatLng(addpoint));
LatLng camloc= new LatLng(lt,lg);
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(camloc, 15));
}
}
And this is from where in MainActivity the MapsActivity is being fired.
direction.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getBaseContext(), "Showing directions", Toast.LENGTH_LONG).show();
TinyDB tinydb = new TinyDB(MainActivity.this);
olati=tinydb.getDouble("destination_lati",lati);
olongi=tinydb.getDouble("destination_longi",longi);
Gson gson = new Gson();
String jsonString = gson.toJson(locs);
Intent intent = new Intent(MainActivity.this,MapsActivity.class);
intent.putExtra("KEY_LOCATIONS",jsonString);
startActivity(intent);
}
});
I don't know what of Logcat shall I post. How do I sort it out? Thanks in advance.
EDIT : Added Error Logcat
This is something around where the application crashes
