Android application, & ldquo; Source not found & rdquo; Debug Error - tried to download the Android source code


I'm getting an error in my Android app that says "source not found" and crashes the program. I've already read a number of posts saying that the solution is to download the android source code and load that up in Eclipse, but I tried to no avail.

Here is a bunch of information that may help with my problem, let me know if you need more!


Thread [<1> main] (Suspended (exception RuntimeException))
ActivityThread.performLaunchActivity(ActivityThrea d$ActivityRecord, Intent) line: 2663

ZygoteInit.main(String[]) line: 626
NativeStart.main(String[]) line: not available [native method]

Is it weird that the first entry is 'ActivityThrea d' with the 'd' cut off? If this is the problem, what went wrong and how do I fix it?

The line of code the debug stops on:

public void AddAnimationID(String index, Integer view)
 animations.put(index, view);

'animations' is a Dictionary and is a member of class Alien. I am calling it like:

Alien alien;
alien.AddAnimationID("idle", R.drawable.idle);

I am correct in thinking that R.drawable.idle is an int right? findViewByID takes an int for the argument...

Here is the logcat, I tried to pinpoint where in the log it started the application, sorry if its too much.

Here is the class Alien:

package Game.Main;

import java.util.Dictionary;

import android.widget.ImageView;

public class Alien
    private AlienState state;
    private Dictionary<String, Integer> animations;
    private ImageView imageView;

    public Alien()


    public void AddAnimationID(String index, Integer view)
        animations.put(index, view);

    public Integer GetAnimationID(String index)
        return animations.get(index);

    public void SetImageView(ImageView view)
        imageView = view;
        if(animations.get("idle") != null)
            state = AlienState.idle;

    public ImageView GetImageView()
        return imageView;

    public void ChangeView(String index)
        if(animations.get(index) != null)
            state = AlienState.valueOf(index);

Here is the onCreate function that this is called from and related information:

package Game.Main;

import java.util.ArrayList;
import java.util.List;

import Game.Main.MainView.MainThread;
import android.content.Intent;
import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.Animation.AnimationListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;

public class Main extends Activity implements OnClickListener {

    private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234;

    private ArrayList<String> dictionary;
    private TextView txtText;

    private MainThread thread;
    private MainView view;

    private AnimationDrawable anim;

    private Alien alien;

    @Override // called when Main is created.
    public void onCreate(Bundle savedInstanceState) {

        // reload from previous instance

        // set default content view

        view = (MainView)findViewById(;
        thread = view.GetThread();

        if (savedInstanceState == null) {
            // we were just launched: set up a new game
            Log.w(this.getClass().getName(), "SIS is null");
        } else {
            // we are being restored: resume a previous game
            Log.w(this.getClass().getName(), "SIS is nonnull");

        // setup speak button
        Button speakButton = (Button)findViewById(;

        // setup text box
        txtText = (TextView)findViewById(;

        // setup our dictionary
        dictionary = new ArrayList<String>();

        alien.AddAnimationID("idle", R.drawable.idle);
        alien.AddAnimationID("jump", R.drawable.jump);
        alien.AddAnimationID("think", R.drawable.think);
        alien.AddAnimationID("sit", R.drawable.sit);

        // check to see if a recognition activity is present
        PackageManager pm = getPackageManager();
        List<ResolveInfo> activities = pm.queryIntentActivities(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);

        // if activities were found, cancel speech recognition
        if (activities.size() != 0)
            speakButton.setText("Recognizer not present");

I am using Eclipse on Windows 7 x64. I have all of the newest updates to the android SDK and I downloaded the android source code and added it to the Eclipse patch because previous posts led me to try that. The code breaks for debug when the first time AddAnimationID is called. I hope this is all you need, thanks! Sorry if I'm doing this wrong by the way, I'm somewhat new at this.

Edit: Looks like I didn't have enough breakpoints, the culprit is not the AddAnimationID function but actually the SetImageView one. The if statement seems to not work, so I've commented it out for now. I'll post back once I've figured it out. It's probably something silly that works in another language but not Java...

The problem ended up being the Dictionary class, I got it to vaguely work by throwing in a bunch of try/catch blocks, but that wasn't what I wanted, so I replaced it with a Map and it works fine.

To append some useful information I've found since then to this answer, as a decent number of people have visited this page: Eclipse will say "Source not found" for nearly every random error you make in your app. Here are some steps to follow in order to locate these troublesome lines of code:

1) Step through your code line-by-line (using step filters to ignore code that you did not write) until you find the offending line, this is most likely where you made your mistake. If the error is deep in the code, place a break point close to, but not after, where you feel the issue occurs and step from there.

2) Uncaught exceptions and other useful information can sometimes be found in the Variables panel.

3) "Source Not Found" just means the line of code that generated the exception is in a binary file. It does exist, Eclipse just can't show it to you.
