Android Eclipse - Could not find *.apk

Question

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 (ie 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 & I have tried removing the debug.keystore, United States as related to issue 834

Answer 1

Please follow these steps; this might help you out:

1. Right-click your app project and go to Properties

2. Select Android from left-hand side list

3. Uncheck the "Is Library" checkbox

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

Answer 2

删除/ Gen文件夹中的R.Java文件对我有用

Answer 3

I tried all the above solutions. but it didn't work.

The solution was to restart eclipse !!!!!!!

hope this will help someone :)

Answer 4

In my case this problem started after eclipse updated the plugin with the v4.0 API release. I fixed it by going to the main preferences for Eclipse and under Android->Build uncheck 'Skip packaging and dexing until export or launch'

Note: if you eclipse gives you the Unknown Command 'crunch' error then follow this post

Answer 5

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

• Check the project is not set as a library:
  1. Go to Project->Properties
  2. Select Android from left-hand side list
  3. Uncheck the "Is Library" checkbox
• Clean and rebuild the project - this should delete and recreate the entire gen folder, including the R.java file mentioned in some peoples answers
• Check eclipse and all the Android plugins are up to date
• Close the project, exit Eclipse, reopen eclipse, reopen the project.
• Go to Java Build Path > Projects and check for any incorrect project dependencies
• Go to the main preferences for Eclipse and under Android->Build uncheck 'Skip packaging and dexing until export or launch'
• Check JAVA_HOME is set correctly. Follow the steps in this article

If you complete the above list, and still haven't solved the issue, please leave a comment, or if you find something else that works, feel free to edit the answer and add your thing in.

Answer 6

Delete the project from your workspace & import again.
This worked for me.

Can't believe similar issue has been there since 2008.

Answer 7

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.

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.

Answer 8

i'm no expert, but eclipse on Windows, doing android apps, refuses to create the default.properties file (in the app root directory). I've just copied one from another app and it works fine. Simple contents, for Android 2.2 project it just says (ignoring comments):

target=android-8

fwiw

Answer 9

以“管理员”身份运行Eclipse，然后导入项目。

Answer 10

None of these things worked for me. I'm trying to access native code through the jni, first with NDK samples. What I found was the build won't run if jarlist.cache is not present in the project bin directory. If I copy one from another project to that location (may need to refresh to see the folder in Eclipse), build works every time.

Answer 11

Clean the project and it will do. Sometimes it happens unknowingly but keep trying to solve using diff methods.

Answer 12

我以某种方式将Run配置为Java应用程序而不是Android。

Answer 13

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.

Answer 14

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.

Answer 15

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.

Answer 16

SHA1's answer did it for me: after updating to the latest sdk/adt, my project refused to build an apk; unchecking the option resolved the issue.

I don't know if the update checked this, or if it was checked before but the new adt screwed things up, but things work again now :)

Answer 17

In my case this worked :

Delete R.Java file in /Gen folder

+

Delete all "R.Android" imports that Eclipse added to some of my java classes !!!

and rebuild the project.

Answer 18

删除-R.java-清理项目并再次运行..这对我有用..

Answer 19

Find the project's folder in your system, enter it's Properties via context menu and deselect "Read only" option. Worked in my case.

This seems to be the source of the problem in many cases, moreover some solutions up there base on copying/rewriting the files in the project what makes them non-read-only.

Answer 20

This is caused by JAVA_HOME not being set correctly. It can be easily resolved by following the steps in this article .

Answer 21

Mine was caused by this problem (incompatibility between ADT and SDK), and was fixed thus:

• Eclipse > Help
• Install New Software
• Add ' https://dl-ssl.google.com/android/eclipse/ ' to 'Work With' section and press enter
• After developer tools appears on the list, check it and click Next
• Restart eclipse once download is finished

Answer 22

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.

Answer 23

对我来说，问题是我试图使用IBM RAD似乎无法正常工作，我安装了Eclipse，现在遇到了另一个错误，但是我应该可以克服它

Answer 24

On my machine (Windows7, 64bit) I could fix this by setting my execution environment to a 32bit variant of the jdk (I used 1.6.0_23). And I tried a lot of things before...
