Please follow these steps; this might help you out:

<ol>
<li>Right-click your app project and go to Properties</li>
<li>Select Android from left-hand side list</li>
<li>Uncheck the "Is Library" checkbox</li>
</ol>

If your app project relies on library projects which are in your workspace, those of course need to have the "Is Library" box checked.

I've tried to gather the best of other peoples answers into a step by step list of things to try in order:

<ul>
<li>Check the project is not set as a library:

<ol>
<li>Go to Project->Properties</li>
<li>Select Android from left-hand side list</li>
<li>Uncheck the "Is Library" checkbox</li>
</ol></li>
<li>Clean and rebuild the project - this should delete and recreate the entire <code>gen</code> folder, including the <code>R.java</code> file mentioned in some peoples answers</li>
<li>Check eclipse and all the Android plugins are up to date</li>
<li>Close the project, exit Eclipse, reopen eclipse, reopen the project.</li>
<li>Go to Java Build Path > Projects and check for any incorrect project dependencies</li>
<li>Go to the main preferences for Eclipse and under Android->Build uncheck 'Skip packaging and dexing until export or launch'</li>
<li>Check <code>JAVA_HOME</code> is set correctly. Follow the steps in <a href="http://dotnetmackenzie.blogspot.co.uk/2011/12/android-could-not-find-helloworldapk.html" rel="nofollow noreferrer">this article</a></li>

I was having the same issue as the OP except that all these suggestions did not work. I found a solution for me.

Make sure that "Skip packaging and dexing until export or launch." is selected.

Go to Window -> Preferences -> Android -> Build. Just make sure that option is selected and apply.

I know this does not make a lot of sense, but having it unselected was giving me this error and with it selected it goes away and the apk is installed.

<hr>

I am using the auto generated ant build script from android and ONLY using it as my build process in eclipse. I am not using any other build methods.

blocks|key|734436|text|我想通了。我引用的是JavaSE-1.5并使用JDK+1.6。我将其更改为使用1.6，这似乎修复了它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|734437|根据我的研究，这似乎是一个重载的错误消息，涵盖了许多错误情况。|734438|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I figured it out. I was referencing JavaSE-1.5 and using JDK 1.6. I changed it to use 1.6 and that appears to fix it. 

Seems like through my research that is an overloaded error message that covers a lot of error cases.

I just fixed this by reselecting a default JRE for the execution environment (JRE6 for JavaSE-1.6 in my case). It got unchecked for some reason.

blocks|key|1720236|text|这解决了我的问题。我在eclipse中不断收到控制台错误“找不到com_android_vending_licensing.apk”，尽管它似乎没有影响我的应用程序运行的方式，但它是恼人的。因此，进入com_android_vending_licensing项目属性并取消选中"is+library“选项，构建项目以生成所需的apk，然后返回到com_android_vending_licensing项目属性并重新选中"is+library”复选框，解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1720237|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This fixed my problem. I kept getting the console error in eclipse "Could not find com_android_vending_licensing.apk" and even though it didnt seem to effect the way my app ran, it was annoying. So going into the com_android_vending_licensing project properties and unchecking the "is library" option, building the project to produce the needed apk and then going back into the com_android_vending_licensing project properties and re checking the "is library" check box fixed the problem.

None of these things worked for me. I'm trying to access native code through the jni, first with NDK samples.

Mine was caused by <a href="https://stackoverflow.com/questions/11227335/this-android-sdk-requires-android-developer-toolkit-version-14-0-0-or-above">this</a> problem (incompatibility between ADT and SDK), and was fixed thus:

<ul>
<li>Eclipse > Help</li>
<li>Install New Software</li>
<li>Add '<a href="https://dl-ssl.google.com/android/eclipse/" rel="nofollow noreferrer">https://dl-ssl.google.com/android/eclipse/</a>' to 'Work With'
section and press enter</li>
<li>After developer tools appears on the list, check it and click Next</li>
<li>Restart eclipse once download is finished</li>
</ul>

blocks|key|1717743|text|就我的情况而言，我不得不从API+21切换到API+19，进行清理和构建，一切都恢复正常。我使用的是Mac，显然Yosemite上并不完全支持API+21。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1717744|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I my case, I had to switch from API 21 to API 19, clean and build and everything was fine again. I am using a Mac and apparently API 21 is not fully supported on Yosemite.

I know this question has been asked before and I have seen a plethora of solutions out there, yet none seem to work for me. I was able to build my apk without issues until this error started cropping up. I have tried cleaning my project, removing it from the workspace and reimporting it, removing "Java Builder" from my Builders for the project, building the project manually, reordering my java build path. I have no visible compiler issues and no problems exist in my workspace. 

I did experience this issue before and solved it once by removing the project form my workspace and re-importing it and another time I solved it by removing "Java Builder" from my java build path. None seem to work this time. I currently have most of the settings set back to default (i.e. java build is checked again).

I am running windows 7 (64 bit) and using jdk1.6.0_21 via Eclipse 3.6. 

Any suggestions would be greatly appreciated as I have lost loads of development time troubleshooting this already.

[Update] My locale is English &amp; I have tried removing the debug.keystore, United States as related to <a href="http://code.google.com/p/android/issues/detail?id=834" rel="noreferrer">issue 834</a>

我知道这个问题以前已经被问过了，我已经看到了太多的解决方案，但似乎没有一个对我有效。我可以毫无问题地构建我的apk，直到这个错误突然出现。我尝试过清理我的项目，从工作区中删除它并重新导入它，从项目的Builders中删除"Java Builder“，手动构建项目，重新排序我的java构建路径。我没有可见的编译器问题，我的工作区中也不存在任何问题。我以前确实遇到过这个问题，有一次通过从我的工作区中删
