Issue in making UPI payment request from android

UPI payment failed in PhonePe while testing my android application.
The error it is showing is - For security reasons, you are not allowed to send money from your bank account for this payment. You don't have to enter UPI PIN to receive money/cashback.

You have created two ImageView i; variables: first in onCreate methon and second in class scope.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
i = findViewById(R.id.imageView); // < here
}
Besides this problem here are some others:
You don't call loadmeme method anywhere
You don't make network request
ImageView imageView; // 1. Use class scoped imageView
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView = findViewById(R.id.imageView);
// 2. Run loadmeme method
loadmeme();
}
public void loadmeme() {
RequestQueue requestQueue = Volley.newRequestQueue(this);
String url = "https://meme-api.herokuapp.com/gimme";
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
String u = null;
try {
u = response.getString("url");
System.out.println("Raunak" + u);
} catch (JSONException e) {
e.printStackTrace();
}
System.out.println("Raunak" + u);
Glide.with(MainActivity.this).load(u).into(imageView);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, "Error occurred", Toast.LENGTH_SHORT).show();
}
});
// 3. Add request to queue
requestQueue.add(jsonObjectRequest);
}

Why my Android App is not scanning Bluetooth device?

Android - Service does not start

I am making app for me and my class mates, that checks for new homeworks and exams. It has service that may not be killed beacuse of checking school server (like every 5 minutes) for changed size of file with list of exams and stuff like this. I tried following code:
MayinActivity.java
package com.test.simpleservice;
import android.app.ActivityManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//checking runings services - remove later
ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);
List<ActivityManager.RunningServiceInfo> rs = am.getRunningServices(50);
String message = null;
for (int i=0; i<rs.size(); i++) {
ActivityManager.RunningServiceInfo
rsi = rs.get(i);
System.out.println("!!!!!!!!!!Service" + "Process " + rsi.process + " with component " + rsi.service.getClassName());
message = message + rsi.process;
}
Button btnStart = (Button) findViewById(R.id.startBtn);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override

ServiceManager.startService(getApplicationContext());
}
});
}
}

Toast.makeText(this, "service start", Toast.LENGTH_LONG).show();
}

}
#Override

//this will NOT kill service
//super.onDestroy();
Toast.makeText(this, "task destroyed", Toast.LENGTH_LONG).show();
Intent in = new Intent();
in.setAction("PreventKilling");
sendBroadcast(in);

When I run the app and click button "start", the service wont start - no toasts, no logs, nothing in setting->apps->services. Why? Any better way to make unkillable process without anoying notification?
logcat
last few lines becouse that before are just listed services:

And one more question: will this app start after boot? If not, what did I do wrong?
im sorry for my poor english

Intent intent = new Intent(context, MyServices.class);
intent.setPackage("com.test.simpleservice");
context.startService(intent);
Because your context is:
public static void startService(Context context)
And here :
public void onReceive(Context context, Intent intent)
For above Intent name -> intent

Splash screen in Android glitch

I have developed a splash screen in Android which comes for 2 seconds and go to the main activity. The problem is that when I start the application the main activity comes for few milliseconds and then goes to the splash screen activity. Can I know the solution for this?
splashscreen.java
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.Window;
import android.view.WindowManager;
public class splashscreen extends Activity {
private static int splashInterval = 2000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
etWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splashscreen);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
Intent i = new Intent(splashscreen.this, MainActivity.class);
startActivity(i);
this.finish();
}
private void finish() {
// TODO Auto-generated method stub
}
},
splashInterval);
};
}
splashscreen.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" >
<ImageView android:src="#drawable/splash" android:layout_width="fill_parent" android:layout_height="fill_parent" android:scaleType="fitXY"/>
<ProgressBar android:id="#+id/progressBar1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:layout_marginBottom="58dp" />
</RelativeLayout>
Android Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="asdf.splashtest1" >
<application android:allowBackup="true" android:icon="#drawable/ic_launcher" android:label="#string/app_name" android:theme="#style/AppTheme" >
<!-- Splash screen -->
<activity android:name=".splashscreen" android:label="#string/app_name" android:screenOrientation="portrait" android:noHistory="true" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Main activity -->
<activity android:name=".MainActivity" android:label="#string/app_name" ></activity>
</application>
</manifest>
//MainActivity.java
package asdf.splashtest1;
import android.support.v7.app.ActionBarActivity;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}

This is my Splash Code Maybe This will helps,
Thread Background = new Thread() {
public void run() {
try {
sleep(2000);
Intent intent = new Intent(splashscreen.this, MainActivity.class);
startActivity(intent);
finish();
} catch (Exception e) {
}
};
Background.start();
}
At sleep(2000), enter your desired time in milliseconds.
Edit
private class SplashTask extends AsyncTask<Void, Void, Void> {
#Override
protected void onPreExecute() {
}
#Override
protected Void doInBackground(Void... params) {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void result) {
finish();
Intent intent = new Intent(SplashActivity.this,
MainActivity.class);
startActivity(intent);
}
}
Call This Async with in onCreate Method new SplashTask().execute();
