Question

I’m trying to create global variables in my application by creating a subclass in android.app.Application. I’ve followed some tutorials on the internet, but I can’t seem to get it working. Eclipse is not giving me any errors, but when I start the application I get the following error: Unfortunately, Application has stopped.

Another person asked the same question on Stackoverflow, but this solution does not seem to work for me.

Here are my application files, any help would be greatly appreciated!

MainActivity.java

package com.app.app;

import org.apache.http.cookie.Cookie;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends Activity {

TextView mTxtvName;

String cookie;
String username;
Cookie theRealCookie;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.overzichttablayout);

    mTxtvName = (TextView) findViewById(R.id.txtvName);

    Globals global = (Globals)getApplication();
    String username = global.getVariable("globUsername");
    String cookie = global.getVariable("globCookie");

    mTxtvName.setText(username);
}

}

Globals.java

package com.app.app;

import android.app.Application;

public class Globals extends Application {

private String globCookie = "null";
private String globUsername = "null";

public String getVariable(String someName) {
    if(someName == "globCookie")
    {
        return globCookie;
    }
    else if(someName == "globUsername")
    {
        return globUsername;
    }
    else
    {
        return null;
    }
}

public void setVariable(String someName, String someVariable) {
    if(someName == "globCookie")
    {
        this.globCookie = someVariable;
    }
    else if(someName == "globUsername")
    {
        this.globUsername = someVariable;
    }
}
}

Application Manifest

</manifest>

I suspect the error is because you declared a second <application /> tag

You should have the Globals declared in the first <application />tag

<application
    android:name="Globals" 
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >

And this line, delete:

<application android:name="Globals" android:icon="@drawable/ic_launcher" android:label="@string/app_name" />
