If you just want to know the conclusion, please go to the last section. Thanks.

Usually when building project fails, some common tricks you could try:

<ul>
<li>Build -> Clean Project</li>
<li>Check Build Variants</li>
<li>Restart Android Studio (as you mentioned)</li>
</ul>

But to be more specific to your problem - when Android Studio could not find the APK file on disk. It means that Android Studio has actually successfully built the project, and also generated the APK, however, for some reason, Android Studio is not able to find the file.

In this case, please check the printed directory according to the log. It's helpful.

For example:

With Android Studio 2.0 Preview (build 143.2443734).

<ol>
<li>Checkout to a specific commit (so that it's detached from head): git checkout [commit_hash]</li>
<li>Run project</li>
<li>Android Studio tells: The APK file /Users/MyApplicationName/app/build/outputs/apk/app-debug-HEAD.apk does not exist on disk</li>
<li>Go to the directory, there is a file actually named: app-debug-(HEAD.apk (with an extra parenthesis)</li>
<li>Run git branch

*(HEAD detached at 1a2bfff)</li>
</ol>

So here you could see, due to my gradle build script's mistake, file naming is somehow wrong.

Above example is just one scenario which could lead to the same issue, but not necessary to be the same root cause as yours.

As a result, I strongly recommend you to check the directory (to find the difference), and check your build.gradle script (you may change the apk name there, something like below):

<pre><code>applicationVariants.all { variant -&gt;
 variant.outputs.each { output -&gt;
 def newFileName = "whatever you want to name it";
 def apk = output.outputFile;
 output.outputFile = new File(apk.parentFile, newFileName);
 }
 }
</code></pre>

Faced the same issue with gradle 1.5

I had to clean the build files:

<blockquote>
 Build -> Clean project
</blockquote>

And build an APK to force the full compilation and sync of the gradle files:

<blockquote>
 Build -> Build APK

I still don't know why or how it happened tho.

Remove the directory ~/.gradle/caches/. It's OK to do this while Android Studio is opened. (Refer pm installing wrong package name)
Press "Sync project with Gradle files" icon on Android Studio
Run the project and the remote path will be correct.

My problem is that I was appending the version number to the APK. Changing the version number and re-syncing Gradle fixed the problem for me.

 variant.outputs.each { output -&gt;
 if (output.zipAlign) {
 def file = output.outputFile
 def removeApp = file.name.replace("app-", "")

 def fileName = removeType.replace(".apk", "." + defaultConfig.versionName + ".apk")
 output.outputFile = new File(file.parent, fileName)

 def file = output.packageApplication.outputFile
 def removeApp = file.name.replace("app-", "")
 def removeType = removeApp.replace("-release", "")
 def fileName = removeType.replace(".apk", "." + defaultConfig.versionName + ".apk")

Make sure that in the path generated in your logs -in your case: 

<blockquote>

folder "outputs" indeed has an "apk" folder.

That was my problem, if it's not there, you will need to run the "assembleRelease" task in gradle by following the below screenshot;

My problem was including minutes in the file name - it looked for appname_debug_0.9.0.1_170214_2216.apk when the generated file was appname_debug_0.9.0.1_170214_2217.apk so the output filename code (nabbed from elsewhere) was clearly being called from two different points in the build.

<pre><code>applicationVariants.all { variant -&gt;
 variant.outputs.each { output -&gt;
 def project = "appname"
 def SEP = "_"
 // def flavor = variant.productFlavors[0].name

 output.outputFile = new File(output.outputFile.parent, newApkName)

Every time this happens I just generate the apk from command line:

Deleting the folder <code>.AndroidStudio[version]</code> and losing all your preferences and caches... seems to solve the problem

I was facing this same problem when I updated to Android Studio 3.1. All other solutions I found here were quite manual because you have to clean and rebuild every time, that is not good at all. But thanks to <a href="https://stackoverflow.com/users/3760297/iman-marashi">Iman Marashi</a>'s answer here I was able to solve it.

Go to Run -> Edit Configurations...

Make sure you have a "Gradle-aware Make" on the Before launch section:

<a href="https://i.stack.imgur.com/9YoVI.png" rel="noreferrer"><img src="https://i.stack.imgur.com/9YoVI.png" alt="Run/Debug Configurations"></a>

I got it to work by:

<ol>
<li>Closing the project</li>
<li>From the Android Studio Welcome Window (or File > New), click on Import Project.</li>

I guess that forced it to reinstall the APK, and now everything is running fine.

All I had to do, was right click on the apk-copy relative path, and just

<pre><code>adb install -r &lt;paste of relative path&gt;

And the apk was installed and good to go.

I tried all of these things and none of them worked. I ended up having to do a couple of these things are the same time. Very frustrating that it took this much time.

The problem I had was related to running my unit tests following the upgrade to AS 3.1.

Here is what I did...
1.) Run / Edit Configurations / Select Tests....
2.) Add options to "Gradle-aware Make"
3.) Select check box "Skip installation if ADK has not changed" on Misc tab

Solved this issue by updating the Android SDK-Build Tools.

blocks|key|2680222|text|在我的例子中，问题是调试配置以某种方式变成了无效的，即使测试方法的名称、类或包没有改变。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|2680223|我在这里从Run->Edit+Configurations中删除了配置：|2680224|​|2680225|📷|atomic|2680226|2680227|Android+studio会自动创建一个新的。|2680228|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/132b8859009cabdd7a8fa1f7815ab04d.png|imageAlt^0|C|D|0|0|0|0|1|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|11|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|12|8|@]|D|@]|E|$]]|$1|J|3|K|5|L|7|13|8|@]|D|@$9|14|A|15|1|16]]|E|$]]|$1|M|3|I|5|6|7|17|8|@]|D|@]|E|$]]|$1|N|3|O|5|6|7|18|8|@]|D|@]|E|$]]|$1|P|3|-4|5|6|7|19|8|@]|D|@]|E|$]]]|Q|$R|$5|S|T|U|E|$V|W|X|-4]]]]

In my case the problem was that debugging configuration become invalid somehow, even that the test method name, class or package has not changed.

I deleted the configurations from Run->Edit Configurations, at here:

Android studio will create a new one automatically.

Sync, Clean, Rebuild and Invalidate Cache and Restart
None of them worked for me.
I have deleted the APK and output.json files in the release folder and debug folder and then tried sync, clean, and build, then it worked fine.
OR simply
Delete folder which has the apk and output.json file (in case of debug/ release)

<code>assemble[Variant]</code> would generate the APK for you on disk although it should not be necessary to use it to debug the app.
Run the following command in the root directory of the project:
<pre><code>$ ./gradlew clean build assemble[Variant]
</code></pre>

When I am trying debug application on Android Studio gives this log output : 

<blockquote>
 The APK file
 /Users/MyApplicationName/app/build/outputs/apk/app-debug.apk does not
 exist on disk.
</blockquote>

I restarted Android Studio, but I can't solve this problem . How can I solve it ? 
Thank you

The APK file does not exist on disk

Android Studio

单元测试

Android

Linux

Unix

当我尝试在Android Studio上调试应用程序时，会给出以下日志输出：磁盘上不存在APK文件/Users/MyApplicationName/app/build/outputs/apk/app-debug.apk 。我重启了Android Studio，但我无法解决这个问题。我该怎么解决它呢？谢谢
