Mi PreferenceActivity no aparece, a pesar de que está en mi archivo de manifiesto

Question

Así que estoy modificando el ejemplo Cubo de pantalla en vivo. Tengo una clase que se extiende PreferenceActivity, y añadí la actividad en mi archivo de manifiesto. Sigo recibiendo ActivityNotFoundExceptions.

Esta es mi clase de preferencia:

package com.p.t.wallpapers.mywallpaper;

import com.p.t.wallpapers.mywallpaper.R;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceActivity;

public class MySettingsActivity extends PreferenceActivity
implements SharedPreferences.OnSharedPreferenceChangeListener {

@Override
protected void onCreate(Bundle bundle) {
    super.onCreate(bundle);
    getPreferenceManager().setSharedPreferencesName(
            ParticleCandy.SHARED_PREFS_NAME);
    addPreferencesFromResource(R.xml.settings);
    getPreferenceManager().getSharedPreferences().registerOnSharedPreferenceChangeListener(
            this);
}

@Override
protected void onResume() {
    super.onResume();
}

@Override
protected void onDestroy() {
    getPreferenceManager().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(
            this);
    super.onDestroy();
}

public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
        String key) {
}

}

Y aquí está mi archivo de manifiesto

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.p.t.wallpapers.mywallpaper"
  android:versionCode="1"
  android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<service 
 android:label="@string/app_name" 
 android:name=".MyWallpaper" 
 android:permission="android.permission.BIND_WALLPAPER" >
 <intent-filter>
  <action 
   android:name="android.service.wallpaper.WallpaperService">
  </action>
</intent-filter>
<meta-data 
    android:name="android.service.wallpaper" 
    android:resource="@xml/wallpaper_info" />  
</service>

<activity
  android:label="@string/settings_title"
    android:name=".MySettingsActivity"
    android:theme="@android:style/Theme.Light.WallpaperSettings"
   android:exported="true">
</activity>

</application>
<uses-sdk android:minSdkVersion="7" />
<uses-feature android:name="android.software.live_wallpaper" />
</manifest> 

Cualquier idea por qué mi actividad preferencias no consigue leer desde el manifiesto? El servicio fondo de pantalla, MyWallpaper aparece muy bien, pero me sigue diciendo DDMS la MySettingsActivity actividad no sale.

Answer 1

descubierto. Era el xml fondo de pantalla que se hace referencia en el manifiesto, bajo la etiqueta de metadatos en la etiqueta de servicio. Básicamente, que tiene XML

<wallpaper 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:settingsActivity="MySettingsActivity"/>

Observe el "MySettingsActivity" hay? Sí, ya que este es un archivo independiente del manifiesto, que no tiene automáticamente un paquete que comienza a buscar nombres de las clases de. Así que todo lo que tenía que hacer era poner la ruta de paquete completo, al igual que

<wallpaper 
xmlns:android="http://schemas.android.com/apk/res/android"
android:settingsActivity="com.p.t.wallpapers.mywallpaper.MySettingsActivity" />

y listo! Mi pantalla de preferencias aparece ahora cuando pulso el botón Configuración ..., en lugar de la fuerza de estrellarse. Oh hombre, facepalm
