android - 动态壁纸设置不显示

Question

当我尝试启动我的动态壁纸的设置按钮时，我收到“动态壁纸选择器 (process.android.process.acore) 已意外停止。”我不太确定为什么。我正在使用 andengine。

这是在我的 main (ParticleWallpaperActivity.java) 中:

package com.particle.wallpaper;

import javax.microedition.khronos.opengles.GL10;

import org.anddev.andengine.engine.camera.Camera;
import org.anddev.andengine.engine.options.EngineOptions;
import org.anddev.andengine.engine.options.EngineOptions.ScreenOrientation;
import org.anddev.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
import org.anddev.andengine.entity.particle.ParticleSystem;
import org.anddev.andengine.entity.particle.emitter.PointParticleEmitter;
import org.anddev.andengine.entity.particle.initializer.AccelerationInitializer;

import   org.anddev.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlasTextureRegionFactory;
import org.anddev.andengine.opengl.texture.region.TextureRegion;

import android.content.SharedPreferences;


public class ParticleWallpaperActivity extends BaseLiveWallpaperService implements     SharedPreferences.OnSharedPreferenceChangeListener {
    // ===========================================================
    // Constants
    // ===========================================================

    public static final String SHARED_PREFS_NAME = "preferences";

    private static final int CAMERA_WIDTH = 480;
    private static final int CAMERA_HEIGHT = 320;
    private static final float RATE_MIN = 8;
    private static final float RATE_MAX = 12;
    private static final int PARTICLES_MAX = 200;

    // ===========================================================
    // Fields
    // ===========================================================

    private Camera mCamera;
    private BitmapTextureAtlas mBitmapTextureAtlas;
    private TextureRegion mParticleTextureRegion;

    //Shared Preferences
    private SharedPreferences mSharedPreferences;

    .....
    .....
    .....

    @Override
public void onSharedPreferenceChanged(SharedPreferences pSharedPrefs, String pKey)
    {

    }

这是我的 (Settings.java) 文件:

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)
{

}
 }

(mjs.xml) 文件:

<?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"/>

最后(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>

//编辑\我的 AndroidManifest.xml 文件:

   <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.particle.wallpaper"
        android:versionCode="46"
        android:versionName="1.4.6">

        <uses-sdk android:minSdkVersion="7" android:targetSdkVersion="7" />

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

    android:name="ParticleWallpaperActivity"
    android:enabled="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:permission="android.permission.BIND_WALLPAPER">
    <intent-filter android:priority="1" >
        <action android:name="android.service.wallpaper.WallpaperService" />
    </intent-filter>
    <meta-data 
      android:name="android.service.wallpaper" 
      android:resource="@xml/mjs" />
</service>
<activity android:name="Settings"></activity>

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


</manifest>

这是我收到错误时的 logcat:

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.

Answer 1

我已经解决了这个问题。看来我必须从以下位置更改我的 AndroidManifest.xml:

<activity android:name="Settings"></activity>

到:

<activity android:name="Settings">
    <intent-filter> 
      <action android:name="android.intent.action.MAIN">
      </action> 
    </intent-filter>
</activity>

Logcat 创造奇迹:)
