    You are probably missing the actual array entries in your strings.xml.
    You should refer to the template that @James Rebello posted earlier in this thread.

    Thanks Vas Yes I missed that value in strings.xml,
    But now giving "No resource found that matches the given name (at
    'defaultValue' with value '@string/background')" this error. I am using LWC 2.6
    I am totally new in android. :(
    Thanks

    You're missing the string entry for background in strings.xml

    Thank you @James Rebello for reply, I got it from @Vas also thanks to vas. Now I've another issue, that I want to add a touch event on wallpaper. Some think is like. elements will spawn by touch, but it will happen also border or random spawn mode.

    hello i am having trouble implementing this code. so i have few questions.

    1. for the first part regarding the list prefrences code. i did not see a shared prefrences xml file. so i assumed that it would go into the lwp_settings.xml file is this correct? ( i only placed it here because i saw other preferences here) or should i have created a folder or something.

    2. secondly i am trying to locate the proper place to put the second part of the code when you mentioned to put the code in the Main Java File:
    In the OnSharedPreference method-... well i was having trouble with this . i went to my livewallpapersettings.java file and was having toruble locating the on shared preference method. Was i looking the right file or should i have been looking in the SBlivewallpaper.java file?

    @Snow Fall
    That's a more advanced feature. I can't help you with it.

    @bsmooth1
    1. Yes, correct.
    2. You need to look at the SBlivewallpaper class. It has the methods you are looking for.

    ok thanks for the help the final question is now that i can add several wall papers to select through in the settings section where exactly am i adding the additional backgorunds in order to make the accesable to the user when they download my wallpaper?

    for example if i wanted to make a addtional wall paper wit hfrosty the snowman on it and have white snowflakes falling from the top of the screen. what files would i need to copy in order to make sure that the 2nd background ,( the frosty the snowman) that im reffering would be able to work properly?

    ok i have tried to implement the code but i am still having a little bit of trouble on step 2. i am using lwp version 2.6 so after looking at this forum i saw that someone posted in stead of using this code;

    selectedBackground = prefs.getString("background_settings",
    "Background 1");
    mBackground = getWallpaperResource();

    that we should use the other code. I copied the other code and put in in the on shared method but im got alot of erros and i am not sure what i did worng or how to correct it.

    below is my code that i put in my my main sblivewallpaper file. can someone please help me out

    yeah when i put the second part of the code into the main java file the one that i posted above into the on shared method i am getting alot of red lines. the reason i am using this code was because i was using lwp version 2.6 as recommended by one of the users. Is there any code that i'm suppose to replace? the code that i am talking about was put in the forum by James Rebello and its on the first page of the forum.

    i tried downloading the sample files that was given but it appears these files were for if you had lwp version 2.1. If you could provide me a example with the code used for version 2.6 it would be greatly apperciated

    You have to modify the code in the following files-SBLiveWallpaper.java, strings.xml, lwpresource.xml
    The part of the code to be modified is placed between specific comments mentioned below.
    For Java file - //LWC 2.6
    For XML file - <!-- LWC 2.6-->

    hello i am having the same problem that user by the name of Ai Fen is having.

    my lwp stop working.
    The option to change the background appear on the Setting but left it black screen

    when setting the livewallpaper after i go to the livewallpaperscreen -->then select my live wallpaper i want to test--> when i try to upload it i just get a black blank screen. The wallpaper does not load. Please help. I have looked over your directions several time. Please help. here is a copy of the code that i put in the SBlivewallpaper.java file:

    if (selectedBackground.equals("Background 1")) {

    res = R.drawable.wallpaper_hdpi;

    if (sfHigh > sfMid) { // use mid resolution image
    scaleFactor = sfMid;
    res = R.drawable.wallpaper_mdpi;
    }

    }

    else if (selectedBackground.equals("Background 2")) {

    res = R.drawable.wallpaper2_hdpi;

    if (sfHigh > sfMid) { // use mid resolution image
    scaleFactor = sfMid;
    res = R.drawable.wallpaper2_mdpi;
    }

    }

    Hey, can someone please explain this more clearly? I don't know what code to put where, and the demo application does not match up with any of the code you listed. Can someone please explain, step by step, in extreme detail where to put what? Perhaps list code above and below where things are supposed to go so I can use eclipse's search feature to find it? Any help would be greatly appreciated.

    @James Rebello, My java file looks nothing like your java file, your example java file looks nothing like how you describe it, and I decompiled your "Serene Rain" live wallpaper and that looks nothing like anything either. Please give more detailed instructions on where to put things. Please use up to date code, and please use reference points so I can find what I need to with eclipse's search feature. Thank you.
