splash screen is not working in android 6

I have added splash screen in my app but the app crashes when is run on Android 6. The interesting thing is that the app runs fine on Android 9.
Don't know what to do.
Target SDK - 28.
min SDK= 19
it is showing error on oncreate method while run app on android 6
splash.java
import android.os.Bundle;
import android.os.Handler;
public class splash extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); // it showing error here.
setContentView(R.layout.activity_splash);
int SPLASH_TIME_OUT = 4000;
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent splashintent=new Intent(splash.this,MainActivity.class);
startActivity(splashintent);
finish();
}
}, SPLASH_TIME_OUT);
}
}

There might be problem with your drawable Image. While copying image Please check the folder in which you are copying.
Try to add the image in drawable folder not drawable-21
I would suggest to remove old image and Add Image again to proper directory.

How to pass a variable to findViewById method using classes and instances? [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 5 years ago.
I've been trying to make this tic-tac-toe game on android studios recently, I only have basic knowledge about android studio and java so i wanted to accomplish this app by making classes and objects, but whenever i try to run my app the app crashes i don't know what's wrong with the code it compiles correctly, can someone help me out?
this is the logcat window:

and this is my MainActivity.java file
package com.example.home.tictactoe;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends AppCompatActivity {
public void clickButton(View view){
Log.i("test","working");
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
class pawn{
int resID = 0;
ImageView object2 = (ImageView) findViewById(resID);
public void showObj()
{
object2.animate().alpha(1f).setDuration(1000);//add code here to change alpha of object
}
public void hideObj()
{
object2.animate().alpha(0f).setDuration(1000);
}
}
final pawn x_11 = new pawn();
final pawn zero_11 = new pawn();
x_11.resID = R.id.x11;
zero_11.resID=R.id.zero11;
x_11.hideObj();
}
}
See picture:

ImageView object2 = (ImageView) findViewById(resID); is called when your pawn object created. At this point you've not set resId for your object yet so it will be 0. This cause object2 to null.
You can change your class like this:
class pawn {
int resID = 0;
ImageView object2;
public pawn(int resID) {
this.resID = resID;
object2 = (ImageView) findViewById(resID)
}
public void showObj()
{
object2.animate().alpha(1f).setDuration(1000);//add code here to change alpha of object
}
public void hideObj()
{
object2.animate().alpha(0f).setDuration(1000);
}
}
Then use it
pawn x_11 = new pawn(R.id.x11);
x_11.hideObj();

Switch between fragments with MapView

I have a main_activity with a bottom bar. I am using this bottom bar to navigate between fragments. However, there's this one fragment that's not directly navigatable via that bottom bar. It must be accessible from the fragment with MapView and upon onInfoWindowClick. However, the app crashes whenever I consume the infoWindow. Here's my code
public void onMapReady(GoogleMap googleMap) {
BitmapDescriptor icon = BitmapDescriptorFactory.fromResource(R.drawable.tesla);
mMap=googleMap;
for (Location item : array_list) {
String _title = item.getLocation_name();
String _snippet = item.getLocation_address();
LatLng _latLng = new LatLng(item.getLatitude(), item.getLongitude());
final MarkerOptions mMarkerOptions = new MarkerOptions().icon(icon);
mMarkerOptions.position(_latLng).title(_title).snippet(_snippet).flat(true);
Marker marker = mMap.addMarker(mMarkerOptions);
mMarkerHashMap.put(marker, item);
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(marker.getPosition())
.zoom(12.0f)
.build();
mMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
#Override
public void onInfoWindowClick(Marker marker) {
LocationDetailFragment detailedlocation = new LocationDetailFragment();
detailedlocation.LOCATION = mMarkerHashMap.get(marker);
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.content, detailedlocation);
ft.addToBackStack(null);
ft.commit();
}
});
}

Instead of:
_campusName = (TextView) getView().findViewById(R.id.campus_name);
_campusAddress = (TextView) getView().findViewById(R.id.campus_address);
use the fragment's inflated view to get the ID's:
_campusName = (TextView) view.findViewById(R.id.campus_name);
_campusAddress = (TextView) view.findViewById(R.id.campus_address);
the exception occurs as your getView() returns null, it is not associated with the fragment's View. In fragment You have to always use the inflated view's reference.

NullPointerException (GameActivity does not open)

Please check whats the problem with my code here :
Main Activity :
I'm using Android Studio. Import statements are managed for me. It won't be necessary to write them here
public class MainActivity extends Activity implements View.OnClickListener {
SharedPreferences prefs;
String dataName = "MyData";
String intName = "MyString";
int defaultInt = 0;
public static int highScore;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button buttonPlay = (Button) findViewById(R.id.btnPlay);
TextView textHighScore = (TextView) findViewById(R.id.textHighScore);
buttonPlay.setOnClickListener(this);
prefs = getSharedPreferences(dataName, MODE_PRIVATE);
highScore = prefs.getInt(intName, defaultInt);
textHighScore.setText("High Score: " + highScore);
}
#Override
public void onClick(View view) {
Intent intent;
intent = new Intent(this, GameActivity.class);
startActivity(intent);
}
}
When I run this application Main Activity is loaded but when I hit play button application closes. I have checked the play button's ID is O.K. I had the same problem in GameActivity but at last I figured out that the problem was with the ID but this time I think problem is with the this I used in Intent();. Activity fails to load.

Please help me out! It took me too much time still I couldn't figure out the problem.

Quoting from your logcat:
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method
'android.content.res.Resources android.content.Context.getResources()'
on a null object reference
at android.content.ContextWrapper.getResources(ContextWrapper.java:87)
at android.view.ContextThemeWrapper.getResources(ContextThemeWrapper.java:81)
at android.view.animation.AnimationUtils.loadAnimation(AnimationUtils.java:75)
at com.cruzerblade.memorygame.GameActivity.<init>(GameActivity.java:55)
This last line is the only line in the trace that is your code:
Look on line 55 of GameActivity.java. It is calling loadAnimation. There is something wrong with the animation it is trying to load (probably a missing resource ID, but it could also be a null or invalid context argument for loadAnimation.)
