I'm still learning how to code Android apps using Android Studio. This is the app I'm trying to write to practice having more than one activity. Everytime I run it it says "Unfortunately Multiactivity has stopped" whenever I type something in the EditText in the main activity page and click the button. 

Perhaps you guys can help me in finding the error? 

AndroidManifest.xml

```

mainactivity.java

```
package rinorapps.com.multiactivity;

import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

public void main_activity_button_listener(View view) {
    Intent intent = new Intent(this, SecondActivity.class);
    String message = main_edit.getText().toString();
    intent.putExtra(EXTRA_MESSAGE, message);
    startActivity(intent);
}
}

```

Second\_activity.xml

```
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent"

<TextView
    android:id="@+id/second_activity_title"
    android:layout_width="match_parent"
    android:layout_height="53dp"
    android:gravity="center"
    android:text="@string/second_activity_title_text"

    android:text="@string/second_edit_text"/>

</RelativeLayout>

```

SecondActivity.java

```
package rinorapps.com.multiactivity;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.EditText;

public class SecondActivity extends AppCompatActivity {

private EditText second_edit;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.second_activity);

    Intent intent = getIntent();
    String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
    second_edit = findViewById(R.id.second_edit);
    second_edit.setText(message);
}
}

```

And then the logcat, which suggests the problem lies in the onClick but that's all I could deduce so far, 

```
 1881-1881/rinorapps.com.multiactivity 
 E/AndroidRuntime: FATAL EXCEPTION: main
 Process: rinorapps.com.multiactivity, PID: 1881
 java.lang.IllegalStateException: Could not execute method for android:onClick"

```

Pasting the whole logcat here seems to mess up the Code format on this website, apologies.

This is the strings.xml file if it helps?

```
<resources>
<string name="app_name">Multiactivity</string>
<string name="main_activity_title_text">Main Activity</string>
<string name="main_activity_button_text">Second</string>
<string name="second_activity_title_text">Second Activity</string>
<string name="main_edit_text">Type here</string>
<string name="second_edit_text">Hello</string>
</resources>

```

I'm not sure if this is the right place, or if I'm doing this properly. I'm studying alone in Kuantan in front of my computer and I have no one around me to ask for help.
