<p>Thanks for your interest in Android! One of the best ways you can help us
improve Android is to let us know about any problems you find with it.</p>
<p>First, though: if you think you've found a security vulnerability,
<em>please don't use the forms below</em>. Using the public forms below may
allow anyone to see your report, which may put users at risk until the bug is
fixed. Please visit
<a href="{@docRoot}source/faqs.html">our
security faq</a> for more information on reporting security vulnerabilities
to the Android security team.</p>
<p>Here's how to report non-security bugs:</p>
<ul>
<li>
<p><a href="https://code.google.com/p/android/issues/advsearch">Search for
your bug</a> to see if anyone has already reported it. Don't forget to
search for all issues, not just open ones, as your issue might already
have been reported and closed. To help find the most popular results,
sort the result by number of stars.</p>
</li>
<li>
<p>If you find your issue and it's important to you, star it! That's how we know which bugs are most important to fix.</p>
</li>
<li>
<p>If no one's reported your bug, file the bug. You can use one of these templates:</p>
<ul>
<li>
<p><a href="https://code.google.com/p/android/issues/entry?template=User%20bug%20report">Bug in your Device</a> - use this if you are a user reporting a bug in a device you own</p>
</li>
<li>
<p><a href="https://code.google.com/p/android/issues/entry?template=Developer%20bug%20report">Bug in the Software</a> - use this if you found a bug in the course of developing an app</p>
</li>
<li>
<p><a href="https://code.google.com/p/android/issues/entry?template=Feature%20request">Feature Request</a> - use this for a feature you'd like to see in a future verison</p>
</li>
</ul>
</li>
</ul>
<p>Keep in mind that an issue tracker is not a user support forum. It is a list
of pending technical tasks, along with information relevant for those tasks,
and information about progress on those tasks including which ones might
get worked on in the short term.</p>
<p>This issue tracker is narrowly focused on the Android Open Source Project.
Issues with retail devices need to be reported through those devices' support
channels, especially for devices other than Nexus. Issues with applications
that aren't part of AOSP need to be reported with those applications'
developers; that is also the case for Google applications.</p>
<p>Please note that we can't guarantee that any particular bug can be fixed in
any particular release. To see what happens to your bug once you report it,
read <a href="life-of-a-bug.html">Life of a Bug</a>.</p>
<p>In general, please put as much info in bugs as you can. Just a one liner
telling us something isn't working is usually useless, and will probably be
closed without any action. The more detail you provide, the more likely your
issue is to be resolved. Below, there are some examples of a good bug report
and a poor bug report.</p>

Title: Error message

When running Eclipse I get an "Internal Error" that says "See the .log file for more details".

Steps to reproduce:
Happens when "Object o = null". Doesn't happen when changed to "Object o".

Expected results:
I wouldn't get the error message--would work with Object o = null.

Observed results:
See above.

<p>This is a poor bug report because it doesn't provide any context for the
issue; is it a problem in the ART runtime, the core framework, or
something else? It also doesn't provide any code or hint on how to reproduce
it. In other words, this bug report doesn't provide enough information for
anyone to take action on, so it would be ignored.</p>

Title: Stepping over "Object o = null" causes Eclipse "Internal Error"

Interesting bug, while using Eclipse 3.3.1.1 with m37a of android and the following code:
<pre>
package com.saville.android;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class TestObjectNull extends Activity {
    /** Called when the activity is first created. */
    &#64;Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);

        Object o = null;

        o = "hi";

        Log.v(TAG, "o=" + o);
    }

    static final String TAG = "TestObjectNull";
}
</pre>
Eclipse indicates an "Internal Error" with "See the .log file for more
details" and then asks if I want to exit the workbench. This occurs when I
place a break point on "setContentView(R.layout.main);" and then single
step over "Object o = null;"

If I change "Object o = null;" to "Object o" all is well.

The last lines of the .log file are:
<pre>
!ENTRY org.eclipse.core.jobs 4 2 2008-01-01 13:04:15.825
!MESSAGE An internal error occurred during: "has children update".
