    Default Robot Game; Few errors (help)

    Hey there!

    I've been following a tutorial on making a game on Kilobolt, but the place is quite dead.
    So I've searched for a more active forum.
    I hope you guys can save me out of this one

    This is my first app ever, so I'm not very familiar with coding.

    I've been following this tutorial:
    (I want to post the link but the forum won't let me.) -> Kilobolt.com -> Tutorials > Game Development Tutorials > Unit 4 > Day 7 - Creating an Android Game (From Start to Finish)

    But I end up getting these errors: Help.jpg

    I've changed all the statements from com.kilobolt.robotgame to my own, com.MertensMobile.AndroidSoldier

    Which fixed the errors I got when adding the classes (Animation.java, Assets,java etc.)

    This is what I get now.

    What am I missing?



    Ty all very much!

    Welcome to the Forum! Please read this topic to learn how to post code correctly and other useful tips for newcomers.

    Copy and paste errors directly into a post, if possible; post code in code tags as described in the above link. The picture you posted is next to impossible to read.

    Good luck!

    Update: The linked picture is much better, though I'm not sure what useful info it provides.

    (I fixed the Map1.text - error.)


    Sorry.

    Thank you for informing me

    The code from the SampleGame.java which gives an error:
    package com.MertensMobile.AndroidSoldier;
     
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.InputStreamReader;
     
    import MertensMobile.R;
    import android.util.Log;
     
    import com.kilobolt.framework.Screen;
    import com.kilobolt.framework.implementation.AndroidGame;
    import com.MertensMobile.AndroidSoldier.R;
     
     
    public class SampleGame extends AndroidGame {
     
        public static String map;
        boolean firstTimeCreate = true;
     
        @Override
        public Screen getInitScreen() {
     
            if (firstTimeCreate) {
                Assets.load(this);
                firstTimeCreate = false;
            }
     
            InputStream is = getResources().openRawResource(R.raw.map1);
            map = convertStreamToString(is);
     
            return new SplashLoadingScreen(this);
     
        }
     
        @Override
        public void onBackPressed() {
            getCurrentScreen().backButton();
        }
     
        private static String convertStreamToString(InputStream is) {
     
            BufferedReader reader = new BufferedReader(new InputStreamReader(is));
            StringBuilder sb = new StringBuilder();
     
            String line = null;
            try {
                while ((line = reader.readLine()) != null) {
                    sb.append((line + "\n"));
                }
            } catch (IOException e) {
                Log.w("LOG", e.getMessage());
            } finally {
                try {
                    is.close();
                } catch (IOException e) {
                    Log.w("LOG", e.getMessage());
                }
            }
            return sb.toString();
        }
     
        @Override
        public void onResume() {
            super.onResume();
     
            Assets.theme.play();
     
        }
     
        @Override
        public void onPause() {
            super.onPause();
            Assets.theme.pause();
     
        }
    }

    The other error I'm getting is from the AndroidManifest.xml

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
       package="com.MertensMobile.AndroidSoldier"
       android:versionCode="1"
       android:versionName="1.0" >
     
        <uses-permission android:name="android.permission.WAKE_LOCK" />
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
        <uses-permission android:name="android.permission.VIBRATE" />
     
        <uses-sdk
           android:minSdkVersion="8"
           android:targetSdkVersion="17" />
     
        <application
           android:icon="@drawable/icon"
           android:label="RobotGame" >
            <activity
               android:name=".SampleGame"
               android:configChanges="keyboard|keyboardHidden|orientation"
               android:label="RobotGame"
               android:screenOrientation="landscape" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
     
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>
     
    </manifest>

    The error here is "@drawable/icon"

    If you need more information, let me know and I'll post it.

    I recommend reading up on Android resources. @drawable/icon is trying to reference an image called 'icon.png' in the drawables directory which probably doesn't exist. map1.txt should be formatted as xml in strings.xml (which lives in the values directory). When you reference R.id.something you are trying to access an id of a layout or UI component specified in the res directory.

    I've checked it, and I do have an Icon.png in the map Android Soldier\res\drawable-hdpi, like mentioned in the tutorial.

    The map1.txt is fixed (how do I format it in strings.xml?)

    Icon.png or icon.png... It's case sensitive. Your IDE should be able to autocomplete this for you.

    <string name="map1">
        All your strings belong to us..
    </string>

    Then access that string with

    String map = getResources().getString(R.string.map1);

    No need to mess around with that InputStream

    First of all, ty for your help.

    Unfortunatly:

    1. The "icon.png", which I saved in the map: "Project Android\Android-Soldier\res\raw" has the same cases as the one in AndroidManifest.xml

    ==

    I think the best way to find the best help would be if I just upload my whole file, it'll be much faster to find what I'm doing wrong

    (Sorry for being so annoying )

    Why is it in /res/raw? Images live in /res/drawable. Also, I'd recommend sticking to the conventions in the android docs with naming resources. I stick to "ic_launcher" for the applications icon.


    You'll notice a couple of different drawable directories (hdpi, xhdpi, etc). These relate to the different screen resolutions. If you plan on supporting multiple devices you need an icon for each directory. There is a breakdown of the sizes here. There are also online tools to automatically scale things for you. You can ignore these and just stick it in drawable for now.

    I just got that from the tutorial, where it said "icon.png"

    (I changed all the 3 maps with an "icon.png"-file, but no improvement so far.

    Could you please re-upload the correct version, cuzz I'm not following it

    Tutorials are okay I suppose but the Android docs have the final say. Stick with ic_launcher.

    Nope. I'm here to help and guide, not solve your problems for you. Doing so would deprive you of the experience of solving your own problems. Additionally, I don't download .exe files from suspicious file hosts (even if I was running a windows machine).

    Alright, you're right.

    I tried that, I changed all icons back to "ic_launcher" and now it's fixed ! Ty !

    Last error I get is in the SampleGame.java, the import "com.kilobolt.robotgame.r"

    even though I named the other names in the other classes "com.MertensMobile.AndroidSoldier", which didn't give me an error,
    this class has two Imports to com.kilobolt.framework ...
    but the .r-file don't get linked.

    Is this regarding a map or a file which I need to adjust ?

    PS: I do have some files with a smaal /!\ icon, is that a problem, or will it just be fine?

    These are warnings. Hover your mouse over the icon to see what the warning is about. Usually it makes sense to fix the problems that generate warnings because the warnings are there for a reason.

    Hmmm, I got a few warningsigns showing up. (yellow ones)

    I got it on my device, named "RobotGame" while I want it with MY name of the game and MY icon...
    When I want to open the app, an error comes "Unfortunatly, RobotGame has been closed." or something like that.

    This is what the Logcat gives me
    E 07-17 21:29:0... 4332 4332 com.MertensMobile.AndroidSoldier Trace error opening trace file: No such file or directory (2)
    W (same as above) 4332 4332 (same as above) dalvikvm Refusing to reopen boot DEX '/system/framework/hwframework.jar'
    W (same as above) 4332 4332 (same as above) (same as above) threadid=1: thread exiting with uncaught exception (group=0x40e0143 []
    8)
    I see that the errors are from Arraylist. I will recheck on the tutorial, see if I can fix this.

    (Note that I try to fix myself as much as possible)

    --- Update ---

    Yah I can't find a solution for those Arrays

    The warnings from the ArrayList are because they aren't using generics. This is the correct way of defining an ArrayList with type safety ensuring it will only accept objects of a certain type (for example this will only accept String objects).

    List<String> tileArray = new ArrayList<String>();

    As for that error. It looks like there is a missing permission. Try adding this to the manifest

    <uses-permission android:name="android.permission. ACCESS_NETWORK_STATE" />

    I've had a look at the tutorial you've been following. It's not a tutorial, rather a set of copy and paste instructions. Understand that creating a game for Android is a complex undertaking, requiring a solid grasp of Java concepts and the problem solving skills that only come with experience.

    I'd advise you to start small and work up. Have you written a "Hello, World" app? A box that bounces around a canvas? A non-trivial app that serves a purpose? If not then you are not ready to make a game.

    You're right.

    I followed your advice on it.

    I just made my first "Hello World"-app, at least this one works!

    So I guess, the next step is the bouncing box
