One of the best ways you can help us 27 improve Android is to let us know about any problems you find with it.</p> 28 <p>First, though: if you think you've found a security vulnerability, 29 <em>please don't use the forms below</em>. Using the public forms below may 30 allow anyone to see your report, which may put users at risk until the bug is 31 fixed. Please visit 32 <a href="{@docRoot}source/faqs.html">our 33 security faq</a> for more information on reporting security vulnerabilities 34 to the Android security team.</p> 35 <p>Here's how to report non-security bugs:</p> 36 <ul> 37 <li> 38 <p><a href="https://code.google.com/p/android/issues/advsearch">Search for your bug</a> to see if anyone has already reported it.</p> 39 </li> 40 <li> 41 <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> 42 </li> 43 <li> 44 <p>If no one's reported your bug, file the bug. You can use one of these templates:</p> 45 <ul> 46 <li> 47 <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> 48 </li> 49 <li> 50 <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> 51 </li> 52 <li> 53 <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> 54 </li> 55 </ul> 56 </li> 57 </ul> 58 <p>Please note that we can't guarantee that any particular bug can be fixed in 59 any particular release. To see what happens to your bug once you report it, 60 read <a href="life-of-a-bug.html">Life of a Bug</a>.</p> 61 <p>In general, please put as much info in bugs as you can. Just a one liner 62 telling us something isn't working is usually useless, and will probably be 63 closed without any action. The more detail you provide, the more likely your 64 issue is to be resolved. Below, there are some examples of a good bug report 65 and a poor bug report.</p> 66 67 <h2 id="a-poor-bug-report">A Poor Bug Report</h2> 68 <pre> 69 Title: Error message 70 71 When running Eclipse I get an "Internal Error" that says "See the .log file for more details". 72 73 Steps to reproduce: 74 Happens when "Object o = null". Doesn't happen when changed to "Object o". 75 76 Expected results: 77 I wouldn't get the error message--would work with Object o = null. 78 79 Observed results: 80 See above. 81 </pre> 82 <p>This is a poor bug report because it doesn't provide any context for the 83 issue; is it a problem in the Dalvik virtual machine, the core framework, or 84 something else? It also doesn't provide any code or hint on how to reproduce 85 it. In other words, this bug report doesn't provide enough information for 86 anyone to take action on, so it would be ignored.</p> 87 <h2 id="a-good-bug-report">A Good Bug Report</h2> 88 <pre> 89 Title: Stepping over "Object o = null" causes Eclipse "Internal Error" 90 91 Interesting bug, while using Eclipse 3.3.1.1 with m37a of android and the following code: 92 93 package com.saville.android; 94 95 import android.app.Activity; 96 import android.os.Bundle; 97 import android.util.Log; 98 99 public class TestObjectNull extends Activity { 100 /** Called when the activity is first created. */ 101 @Override 102 public void onCreate(Bundle icicle) { 103 super.onCreate(icicle); 104 setContentView(R.layout.main); 105 106 Object o = null; 107 108 o = "hi"; 109 110 Log.v(TAG, "o=" + o); 111 } 112 113 static final String TAG = "TestObjectNull"; 114 } 115 116 Eclipse indicates an "Internal Error" with "See the .log file for more 117 details" and then asks if I want to exit the workbench. This occurs when I 118 place a break point on "setContentView(R.layout.main);" and then single 119 step over "Object o = null;" 120 121 If I change "Object o = null;" to "Object o" all is well. 122 123 The last lines of the .log file are: 124 125 !ENTRY org.eclipse.core.jobs 4 2 2008-01-01 13:04:15.825 126 !MESSAGE An internal error occurred during: "has children update". 127 !STACK 0 128 java.lang.InternalError: Invalid signature: "<null>" 129 at 130 org.eclipse.jdi.internal.TypeImpl.signatureToTag(TypeImpl.java:307) 131 at 132 org.eclipse.jdi.internal.LocalVariableImpl.tag(LocalVariableImpl.java:185) 133 at 134 org.eclipse.jdi.internal.StackFrameImpl.getValues(StackFrameImpl.java:128) 135 at 136 org.eclipse.jdi.internal.StackFrameImpl.getValue(StackFrameImpl.java:73) 137 at 138 org.eclipse.jdt.internal.debug.core.model.JDILocalVariable.retrieveValue(JDILocalVariable.java:57) 139 at 140 org.eclipse.jdt.internal.debug.core.model.JDIVariable.getCurrentValue(JDIVariable.java:66) 141 at 142 org.eclipse.jdt.internal.debug.core.model.JDIVariable.getValue(JDIVariable.java:88) 143 at 144 org.eclipse.debug.internal.ui.model.elements.VariableContentProvider.hasChildren(VariableContentProvider.java:62) 145 at 146 org.eclipse.jdt.internal.debug.ui.variables.JavaVariableContentProvider.hasChildren(JavaVariableContentProvider.java:73) 147 at 148 org.eclipse.debug.internal.ui.model.elements.ElementContentProvider.updateHasChildren(ElementContentProvider.java:223) 149 at 150 org.eclipse.debug.internal.ui.model.elements.ElementContentProvider$3.run(ElementContentProvider.java:200) 151 at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) 152 </pre>
