Android button not opening other class

I have problems with buttons.I have made 2 buttons that will when pressed open other activity(class).In code there is no error but when I launch emulator it just doesn't work and isn't opening those classes.
My button's btnopis and btnpronadi don't work(they are not opening other activity(class)).But I have button exit that Works and closes app. I don't get where the problem is. Here is the code
import android.content.Intent;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
izlaz();
}
public Button btnopis;
public void otvoriopis(){
btnopis=(Button)findViewById(R.id.btnopis);
btnopis.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Intent otvoriopis= new Intent(MainActivity.this,Opis.class);
startActivity(otvoriopis);
}
});
}
public Button btnpronadi;
public void otvoripronadi(){
btnpronadi=(Button)findViewById(R.id.btnpronadi);
btnpronadi.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Intent otvoripronadi= new Intent(MainActivity.this,Pronadi.class);
startActivity(otvoripronadi);
}
});
}
public Button btnizlaz;
public void izlaz(){
btnizlaz=(Button)findViewById(R.id.btnizlaz);
btnizlaz.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
finish();
System.exit(0);
}
});
}
}
here is the manifest code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.shromid">
<application
android:allowBackup="true"
android:icon="#mipmap/app_ikona"
android:roundIcon="#mipmap/app_icon_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".SplashScreen"
android:label="ShromID"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity"/>
<activity android:name=".Opis" />
<activity android:name=".Pronadi"></activity>
</application>
</manifest>

You forgot do call otvoriopis() and otvoripronadi() at onCreate:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
izlaz();
otvoriopis();
otvoripronadi();
}

You should call your functions in onCreate method, like you did for 'izlaz'

import android.os.Bundle;
public class Splash extends Activity {
MediaPlayer ourSong;
#Override

ourSong.start();
Thread timer = new Thread(){
public void run(){
try{
sleep(5000);
} catch (InterruptedException e){
e.printStackTrace();
}finally{
Intent startMain = new Intent("com.example.secondapp.MENU");
startActivity(startMain);
}
}
};
timer.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}
Menu
package com.example.secondapp;
public class Menu extends ListActivity {
String classes[] = {"MainActivity", "example1", "example2", "example3", "example4", "example5"};
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(Menu.this, android.R.layout.simple_list_item_1, classes));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
String Cheese = classes[position];
super.onListItemClick(l, v, position, id);
try{
Class ourClass = Class.forName("com.example.secondapp." + Cheese);
Intent ourIntent = new Intent(Menu.this, ourClass);
startActivity(ourIntent);
}catch(ClassNotFoundException e){
e.printStackTrace();
}
}
}

in your manifest the action should match. Change it with com.example.secondapp.MENU

It is in caps MENU should be Menu
Change to
Intent startMain = new Intent("com.example.secondapp.Menu");
coz your activity is public class Menu extends ListActivity { and in manifest you have
<activity
android:name=".Menu"
Edit:
Explicit intents designate the target component by its name (the
component name field, mentioned earlier, has a value set). Since
component names would generally not be known to developers of other
applications, explicit intents are typically used for
application-internal messages — such as an activity starting a
subordinate service or launching a sister activity.
Implicit intents do not name a target (the field for the component
name is blank). Implicit intents are often used to activate
components in other applications.
So Change to explicit intent
Intent startMain = new Intent(Splash.this,Menu.class); // in Splash.java
and in manifest
<activity
android:name="com.example.secondapp.Menu"
android:label="#string/app_name" >
</activity>
For more info check the docs
http://developer.android.com/guide/components/intents-filters.html

You need to set activity class in your manifest and you misspelled MENU
replace
<activity
android:name=".Menu"
android:label="#string/app_name" >
with
<activity
android:name=".MENU"
android:label="#string/app_name" >

I have tried cleaning the project, re-writing the manifest and everything i can possible think of. It works if i comment out the links to the buttons in the code and leave them in the manifest but the moment i uncommnet them i get these errors, please help!!!

The problem is that the activity throw exception.
eclipse looks for the source code in android SDK and can't find it.
Just debug your code and find out where the code throw exception.

solved it, feeling pretty stupid now, needed bstart not bcstart when the button is defined.

Fortumo In-App payment for Android

I'm trying to create a application, where you can buy In-App credits with the Fortumo service. I've managed to get the makePayment(); method working so I can make a payment and everything seems to work. The only thing is, that it looks like the onReceive(); is never called because the credits count is not changed after a successful payment. The credits count should be increased by 32000 with one payment of 0.32€.
Here is the main activity java:
package com.your.raha;

So basically I'm trying to start the Soundboard.Osteti(); in the Soundboard.java that adds 32000 to the counter int and then updates the TextView. But nothing happens.
Hope somebody can help me. Thanks!

I'm still trying to make this work.
There is this thing I think you've wrong in your manifest:
PaymentStatusReceiver it's not an activity, and you only need to configure that as a receveiver (as you already had).
