PackageInfo versionCode and versionName null on phone, but works on emulator - android-emulator

Question

I am building a private app that will not go through the Marketplace. As a result, I need to pull the current version application (not platform) information and check with the server to see if there is an update. It works great on the emulator, but when I installed the signed APK on my Droid X, it returns null. Here is the code:
PackageInfo pInfo = null;
try {
pInfo = getPackageManager().getPackageInfo("com.rubiconproject.expenses",
PackageManager.GET_META_DATA);
} catch (NameNotFoundException e) {
return;
}
String postUrl = DbAdapter.REMOTE_DB +
"/application/active-version/platform/android/version/" +
pInfo.versionCode + "." + pInfo.versionName;
EDIT:
I wrote a much smaller application, below, that displays my problem (TestingActivity.java):
package com.rubiconproject.testing;
import android.app.Activity;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.os.Bundle;
import android.widget.TextView;
public class TestingActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
PackageInfo pInfo = null;
try {
pInfo = getPackageManager().getPackageInfo(
"com.rubiconproject.testing", PackageManager.GET_META_DATA);
} catch (NameNotFoundException e) {
return;
}
TextView tt = (TextView)findViewById(R.id.textView1);
tt.setText(pInfo.versionCode);
TextView tt2 = (TextView)findViewById(R.id.textView2);
tt2.setText(pInfo.versionName);
}
}
And the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.rubiconproject.testing"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="9" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".TestingActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
adb logcat shows:
E/AndroidRuntime( 335): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.rubiconproject.testing/com.rubiconproject.testing.TestingActivity}: java.lang.NullPointerException

where line 26 corresponds to:
tt.setText(pInfo.versionCode);
Does anyone know why this is happening?

Answer 1

Does your manifest.xml contain android:versionCode and androd:versionName attributes?
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.package.name"
android:versionCode="2"
android:versionName="1.1">
<application android:icon="#drawable/icon" android:label="#string/app_name">
...
</application>
</manifest>

Answer 2

Figured it out. The problem was between the keyboard and the chair. I was seeing null, when it fact the string was being built improperly.
