When I try to launch the settings button for my Live Wallpaper I get a “Live Wallpaper Picker (process.android.process.acore) has stopped unexpectedly.” And I’m not really sure why. I am using andengine.
This is inside my main (ParticleWallpaperActivity.java):
package com.particle.wallpaper;
import javax.microedition.khronos.opengles.GL10;

@Override
public void onSharedPreferenceChanged(SharedPreferences pSharedPrefs, String pKey)
{
}
Here is my (Settings.java) file:
package com.particle.wallpaper;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceActivity;
public class Settings extends PreferenceActivity implements SharedPreferences.OnSharedPreferenceChangeListener
{
@Override
protected void onCreate(Bundle icicle)
{
super.onCreate(icicle);
getPreferenceManager().setSharedPreferencesName(ParticleWallpaperActivity.SHARED_PREFS_NAME);
addPreferencesFromResource(R.xml.preferences);
getPreferenceManager().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
}
@Override
protected void onResume()
{
super.onResume();
}
@Override
protected void onDestroy()
{
getPreferenceManager().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
super.onDestroy();
}
@Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key)
{
}
}
The (mjs.xml) file:
<?xml version="1.0" encoding="UTF-8"?>
<wallpaper
xmlns:android="http://schemas.android.com/apk/res/android"
android:thumbnail="@drawable/icon"
android:description="@string/app_description"
android:settingsActivity="com.particle.wallpaper.Settings"/>
And finally (preferences.xml):
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:title="First Category">
</PreferenceCategory>
</PreferenceScreen>
//EDIT\
My AndroidManifest.xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Here is my logcat when I get the error:

There must be something very simple that I'm missing, but I just can't seem to figure it out. Any help would be greatly appreciated.
I have fixed the problem. It seems I had to change my AndroidManifest.xml from:
to:
Logcat works wonders 🙂
