Android studio completes the building process then says that build failed
"I have tried cleaning the project & rebuilding it but it ends up with the same result"
output:
buildOutput.apkInfo must not be null
EDIT: I figured my problem here and it seems like some how my package changed and I fixed it with reversing the changes.
If you came here to solve a similar problem check this link first Cause: buildOutput.apkData must not be null
For Android Studio 3.5 Update. (APK signed issue)
I had the same issue. I have resolved this issue by modifying the Destination Folder.
Step by step
Build
Generate signed Bundle/APK
Select Android App Bundle or APK
Add Keystore
On Destination Folder: Change c:\user\folder\project\app to c:\user\folder\project\
Summary
Before
c:\user\folder\project\app
After
c:\user\folder\project\
In my case, just simple steps started to work:
Delete the build folder of App and inner Modules.
Clean Project.
Rebuild Project.
That's it.
I'm trying to generate a signed APK for my app in Android Studio by going into Build->Generate Signed Bundle/APK , but I keep getting this error when I select the release build variant.
Execution failed for task ':app:packageRelease'.
Failed to read key keystore from store "C:\Users[PATH]\keystore.jks": Keystore was tampered with, or password was incorrect
I'm pretty sure that my password is correct because the apk generates correctly when I select the debug build variant instead of release. The keystore also works fine for my other projects.
I tried cleaning, rebuilding the project,invalidating the cache/restarting, and changing the destination folder, but nothing worked. Does anyone know why this is happening and how I could solve it?
Check your keystore file for first, in you example you creating file with name keystore.jks If its correct and really present in folder user check alias
Turns out that the problem was my build.gradle version.
Same solution as #S. Gissel in Cannot compile a signed APK in Android Studio 3.3
I was able to solve this by providing the specific file path of my .jks and not just the folder.
ex.
INCORRECT key store path
C:\Users\john\Desktop\Projects\ProjectName
CORRECT key store path
C:\Users\john\Desktop\Projects\ProjectName\helloworld.jks
I started using new Android Studio and cant find the APK of the application in IDE,where it actually locates?
To help people who might search for answer to this same question, it is important to know what type of projects you are using in Studio.
Gradle
The default project type when creating new project, and the recommended one in general is Gradle.
For a new project called "Foo", the structure under the main folder will be
Foo/
settings.gradle
Foo/
build.gradle
build/
Where the internal "Foo" folder is the main module (this structure allows you to create more modules later on in the same structure without changes).
In this setup, the location of the generated APK will be under
Foo/Foo/build/apk/...
Note that each module can generate its own output, so the true output is more
Foo/*/build/apk/...
EDIT
On the newest version of the Android Studio location path for generated output is
Foo/*/build/outputs/apk/...
IntelliJ
If you are a user of IntelliJ before switching to Studio, and are importing your IntelliJ project directly, then nothing changed. The location of the output will be the same under:
out/production/...
Note: this is will become deprecated sometimes around 1.0
Eclipse
If you are importing Android Eclipse project directly, do not do this!
As soon as you have dependencies in your project (jars or Library Projects), this will not work and your project will not be properly setup.
If you have no dependencies, then the apk would be under the same location as you'd find it in Eclipse:
bin/...
However I cannot stress enough the importance of not doing this.
I am on Android Studio 0.6 and the apk was generated in
MyApp/myapp/build/outputs/apk/myapp-debug.apk
It included all libraries so I could share it.
Update on Android Studio 0.8.3 Beta. The apk is now in
MyApp/myapp/build/apk/myapp-debug.apk
Update on Android Studio 0.8.6 - 2.0. The apk is now in
MyApp/myapp/build/outputs/apk/myapp-debug.apk
There is really no reason to dig through paths; the IDE hands it to you (at least with version 1.5.1).
In the Build menu, select Build APK:
A dialog will appear:
If you are using a newer version of Android Studio, it might look like this:
Clicking the Show in Explorer or locate link, you will be presented with a file explorer positioned somewhere near wherever Android Studio put the APK file:
But in AS 3, when you click locate, it puts you at the app level. You need to go into the release folder to get your APK file.
In my case, I'm using Android Studio 1.0.2, I get my APK file from:
<myAndroidProject>/app/build/outputs/apk/app-debug.apk
If anyone would be missing his APK and couldn't find it in the locations stated in other answers (I found this question, since I couldn't find it either) it might just be in this folder (mine was)
<project folder>/target/classes/<appname>.apk
I also had a there this file:
<appname>.unaligned.apk
I am not perfectly sure, whether the apk is actually the full-blown apk, which should be generated, but I tried it on various devices (not only the target device, but also those which were supporting only the minimum SDK) and it worked.
Hope this will help someone.
It is Project_Location/app/build/outputs/apk for Gradle Project
Find apk using below step:-
Goto to your project folder.
Open project folder.
Open build folder.
Open output folder.
Open apk folder.
Now you see your apk.
hope it will help some body.
So the apk in Android studio is generated inside build folder of app module.
Correct path to apk would be \app\build\outputs\apk. I am using Android Studio Version 1.4.1. So apk could either be found at app/build/apk/ or \app\build\outputs\apk base on the version of Android studio you are using. Refer the below image
Also find more reference on these links.
Building and Running from Studio
Studio Project Overview
I'm using Android Studio and gradle.
It created the build/apk/<.apk> file only when I ran the project.
Press the following to run your project: Alt+u, u
Android Studio: 0.5.3
Gradle: 0.9.+
You can find the APK in:
YourProject\app\build\outputs\apk
The .apk file is located at [your project]\out\production\[your project name]
In the new Android Studio, the signed apk is placed directly in the folder of module for which the apk is built.
For example: For a Project ProjectA containing 2 modules Mod1 and Mod2, the apk files will be found in
/path-to-ProjectA/Mod1/Mod1.apk
/path-to-ProjectA/Mod2/Mod2.apk
Image for APK location in Android Studio
Location of apk in Android Studio:
AndroidStudioProjects/ProjectName/app/build/outputs/apk/app-debug-unaligned.apk
As of version 0.8.6 of Android Studio generating an APK file (signed and I believe unsigned, too) will be placed inside ProjectName/device/build/outputs/apk
For example, I am making something for Google Glass and my signed APK gets dropped in /Users/MyName/AndroidStudioProjects/HelloGlass/glass/build/outputs/apk
I got the .apk files in
parent_folder/out/production/projectname/projectname.apk
Build your project and get the apk from your_project\app\build\apk
You can find your apk file as follow:
yourproject>app>build>output>apk>yourproject.apk
The Android build system is the toolkit you use to build, test, run
and package your apps. The build system can run as an integrated tool
from the Android Studio menu and independently from the command line.
You can use the features of the build system to:
Customize, configure, and extend the build process.
Create multiple APKs for your app with different features using the
same project and modules.
The build process involves many tools and processes that generate intermediate files on the way to producing an .apk. If you are developing in Android Studio, the complete build process is done every time you run the Gradle build task for your project or modules.
The build process is very flexible so it's useful, however, to understand what is happening under the hood since much of the build process is configurable and extensible. The following diagram depicts the different tools and processes that are involved in a build:
Build a release version
You can now use the Build menu options to build the release version of your application for distribution.
The build generates an APK for each build variant: the app/build/apk/ (or app/build/outputs/apk) directory contains packages named app--.apk; for example, app-full-release.apk and app-demo-debug.apk.
Build output
The build generates an APK for each build variant in the app/build folder: the app/build/outputs/apk/ directory contains packages named app--.apk; for example, app-full-release.apk and app-demo-debug.apk.
Courtesy goes to Build System Overview
I am using Android Studio 3.0 canary 6.
To build apk,
Click to Build->Build APK(s).
After your apk is build, Go to:
C:\Users\your-pc-name\AndroidStudioProjects\your-app-name\app\build\outputs\apk\debug
If you have imported a Project from Eclipse and are using the new Android Studio
The directory
/bin
does exist (there maybe old binaries in here) however with the latest Android Studio update the actual current apk is stored in
/out/production
Add this in your module gradle file. Its not there in default project. Then u will surely find the APK in /build/outputs/apk/
buildTypes {
debug {
applicationIdSuffix ".debug"
}
}
open Event Log
find line: Module 'app': locate or analyze the APK.
click on locate link to open folder with apk file!
After all: "All built APKs are saved in project-name/module-name/build/outputs/apk/ Build your project LINK
Hint: If you can´t see the app-debug.apk in your debug folder, you have to click on BUILD --> Rebuild Project in Android Studio.
To create apk in android studio,go to build menu->build bundles/apk->build apk
it will make the apk file of your project.After this the apk will be available in your
project directory->app->build->outputs->apk->debug->app-debug.apk
Click on Build-Build Bundles/Apks-Build Apk.
A notification will which shows app location when you click on 'locate' on the notification.
If you have already done creating apk, goto : C:\Users\\AndroidStudioProjects\\app\build\outputs\apk\debug
For Gradle look here: https://docs.gradle.org/current/dsl/org.gradle.api.tasks.SourceSetOutput.html.
"For example: Java plugin will use those dirs in calculating class paths and for jarring the content; IDEA and Eclipse plugins will put those folders on relevant classpath."
So its depend on plugin build in configs unless you don't define them explicit in config file.
Click the little gear icon in the project view and make sure "show excluded files" is checked. Otherwise, the IDE will hide output and several other important directories under $project/$module/build/.
Hello all above all answers are right you can find the apk through the path in android studio but there is exceptions you can't find the build/output
folder some times if you can't see it just go to
app--> app.iml file and find below line in it :-
<excludeFolder url="file://$MODULE_DIR$/build/outputs" />
--> after removing this line you can see the output folder its just the adding more information to above answers as per my experience :)
THANKS!~!
For Android Studio 2.0
C:\Users\UserName\AndroidStudioProjects\MyAppName\app\build\outputs\apk
Here
UserName is your computer user name and
MyAppName is your android app name
As of Android Studio 3.0 / Gradle Build Tools 3.0.0, APK artifacts can now be found in foo/bar/build/outputs/apk/flavorName/buildType with respect to your project name, foo, and your module name, bar. There is now a directory for each apk file sorted organized first by flavor (with respect to flavor dimensions) and then by build type.
My app was running perfect until i added a new graphic background in a button.From this time i m getting a message when i m trying to rum my app "You project contains error(S), please fix them before running your application". I have tried to clean my app, refresh it but nothing changes.Also,in the package explorer there is no red sign nowhere in that project....I import the same project in my Macbook and its running with no problem.So,where is the problem in that pc eclipse?Thanks
I recently had this issue. The issue was caused because my debug certificate had expired. So what I did was go to the .android location in windows and delete the file debug.keystore.
After deleting, I cleaned and build my project, this fixed the issues. In my machine this was the location of the keystore, you might need to search
E:\Users\blessan\.android
reference entry of any updated file is still not updated , so R contains error . i know in gen folder R is not red crossed .
work around is open recently changed res files (layout/values ) make little changes (so that new reference can be saved ) and save it . now clean and build .
I also encountered same problem. When I tried to run my project, the error message is displayed "You project contains error(S), please fix them before running your application". But when I build the project, there was no error and same error again on running my app.
So, I went to Build Path -> Configure Build Path -> Java Build Path, and there was an extra entity other than Android 3.1(in my case). So I removed that and application runs good.
