Meine PreferenceActivity nicht angezeigt, auch wenn es in meiner Manifest-Datei ist

StackOverflow https://stackoverflow.com/questions/2614134

Frage

Also habe ich die Cube Live Wallpaper Beispiel bin zu modifizieren. Ich habe eine Klasse, die PreferenceActivity erstreckt, und ich hinzugefügt, um die Aktivität in meiner Manifest-Datei. Ich erhalte ActivityNotFoundExceptions.

Hier ist meine Vorlieben Klasse: 

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) {
}

}

Und hier ist meine Manifest-Datei 

<?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>

Irgendwelche Ideen, warum Tätigkeit meiner Vorlieben nicht in dem Manifest gelesen werden? Die Tapete Service, MyWallpaper zeigt sich ganz gut, aber DDMS hält mich die Aktivität MySettingsActivity sagen nicht beendet.

War es hilfreich?

Lösung

es herausgefunden. Es war die Tapete xml, die im Manifest verwiesen wird, unter dem Metadaten-Tag in dem Service-Tag. Im Grunde genommen, dass xml hat 

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

Beachten Sie die "MySettingsActivity" da? Ja, da dies eine separate Datei aus dem Manifest ist, ist es nicht automatisch ein Paket hat es von Klassennamen beginnt mit der Suche. Also alles, hatte ich das volle Paket Weg wurde gelegt zu tun, wie so 

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