Android test project fails to build under Ant, OK in Eclipse - android

I am trying to set up a CI build server for an Android app project and its JUnit test project. I've generated the appropriate build.xml files for both app and test projects.
Both projects build and execute fine under Eclipse.
However, when I try to do ant debug on the test project without having first built both projects with Eclipse, I get several [javac] errors saying error: cannot find symbol which refer to classes in the app project.
I think this is a difference between the classpath that Eclipse sees and the classpath that Ant is using...
How do I tell Ant where to find the app classes?
It seems the Android default build.xml defines all the targets, so I was wondering how to insert the appropriate reference in the app project's build.xml... rather than having to start the build file from scratch.
Tried exporting the Ant build file from Eclipse; that fails to build either project.

What seems to work is to re-run:
android update test-project -m ../../app_project/ -p .
within the test project.
The only change it made was to create an ant.properties file with one non-comment line:
tested.project.dir=../../app_project/
And now it all works swimmingly outside of Eclipse!

Specifying gradle file (not default build.gradle file) to build android studio standard project

For different purpose, I need to specify another gradle file (not default build.gradle file) to build android project in android studio standard structure. When using eclipse with gradle, I know how to build project with specified name gradle file. Since the structure is a little different. How to make it work? Does anybody know it? Thanks
More details to be explained.
I have an Android Studio standard project structure as below.
->Root
-->app
-->settings.gradle
-->build.gradle
-->Project1 (library)
-->Project2 (library)
-->build.gradle
-->settings.gradle
I want to create a new gradle file to build project to generate apk file. This gradle file has some tasks than the default one (build.gradle).
So I can choose one of them to use for different purpose.
For example, for A purpose, I can execute 'gradle assembledebug' to generate apk file.
for B purpose, I can execute 'gradle assembledebug -b b.gradle' to generate apk file.
I have done some research on this, but failed.

Apk location in New Android Studio

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.

Building Android library with Eclipse vs Ant

I have a simple Android library project, which contains network calls functionality only. It doesn't need to inherit any XML/resources etc… to calling application. When I build this project using Eclipse IDE (right click on project and click on Build Project), it generates a JAR under bin/libproject.jar. I can simply drop this file to any project's build path and it works fine.
Now, I want to implement continuous integration for my library. That means, I need some command-line way to achieve the same (building jar, when I build the project using ant). Ant builds the project differently. It creates classes.jar in bin/ folder, which is not the same as as libproject.jar.
I believe Eclipse's Build Project (ADT rev-21) is doing something magical to build this complete JAR for my library project (this is more like a java project like JAR).
Do you know how can I achieve the same using command line?
im using eclipse 4.3 w/ ant and with sdk tools 21.1
IMO - they recently changed the sdk regarding lib dependencies.
http://tools.android.com/recent/dealingwithdependenciesinandroidprojects
see the above link.
my example lib dependency(transitive) as follows:
ABS <== SlidingMenu <== MyProject
so, in SM.project.properties...
android.library.reference.1=../../src/ABS/library
and, in MP.project.properties ...
android.library.reference.1=../../src/SlidingMenu/library
The ant build, run on proj=SM using either eclipse internal, ant build tools OR ant on CLI in a terminal session outside eclipse
does following:
[javac] Note: Recompile with -Xlint:deprecation for details.
[echo] Creating library output jar file...
[jar] Building jar: /home/rob/src/tools/ActionBarSherlock-4.2.0/library/bin/classes.jar
and ant build, run on proj=MP does the following:
Setting project property: out.library.jar.file -> /home/rob/src/SlidingMenu/library/bin/classes.jar
..
[jar] Building jar: /home/rob/src/SlidingMenu/library/bin/classes.jar
IMO - you should focus on 2 things :
get the lib reference correct in the file=project.properties of the dependent.
double check in eclipse the project /properties/ java build path / order and export
read the link as it contains multiple , specific NOTEs relating to 'order export'...
When you build the dependent project in ant , it should trigger internally, builds of the other projects. I think that is controlled in the build path of the dependent project.
An additional NOTE on debugging - i could not debug directly from the project explorer because the launcher did not like the "classes.jar" for the 2 , dependent projects. Debug insisted on there being jars with names "${project-name}.jar" in the ./bin directory of each library. But ant assigns "classes.jar" as shown above.
So, to debug, i used the alternate method of DDMS tab in eclipse w/ the app already running. then u find the process and attach the debugger.

Adding android library project to an android project prevents Ant from building

I'm adding an android library project to my android app (in this case, Beintoo). It's not mine; It's an external library. However, it doesn't come with a build.xml. Building in Eclipse works fine, but when I attempt to build my app with ant, I get this:
BUILD FAILED
C:\Sandbox\MyProject\build.xml:110: The following error occurred while executing this line:
C:\Sandbox\MyProject\build.xml:41: The following error occurred while executing this line:
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:515: Invalid file: C:\Git\Beintoo-Android\beintoo-android-sdk\BeintooSDK\build.xml
It's perfectly true. The file is invalid, because it doesn't exist. I wouldn't know what to do to add it safely, nor if that's even a good idea.
I have learnt that I can't simply build the library project into a jar. How can I get my project to build in Ant with this library project?
Ok, so, Error 454's answer was close, but not quite right. Since r14 of Android Tools, every library project must have it's own build.xml if it is to be built by Ant, as noted here:
https://groups.google.com/forum/?fromgroups#!topic/adt-dev/Z2e3dY-3Ma0
Running android update lib-project (which, as Error 454 notes, is in the android-sdk/tools folder which should be in PATH) on the library project will add a generic build.xml, and allow the main project to build.
For library projects, you need to browse to the library project root and run:
android update lib-project -p .
The android executable is in the android sdk/tools folder which should be added to your path variable in your OS. Once you run this, the necessary build files will be generated and your ant build should succeed.
Similarly, if your root project doesn't have the necessary build files, you will need to browse to the main project root and run:
android update project -p .
Additionally to the two previous correct answers I had to add --target android-16 because I was getting an "Error: The project either has no target set or the target is invalid."
So in my case
android update lib-project -p . --target android-16
Did it. (replace the 16 as you need)

Build Android Library Project With Ant

I am having trouble building my Android library project with ant. When I try to run ant release, it says Target "release" does not exist in the project "MyProject".
I then assumed that perhaps libraries do not get build with release/debug, so I started using ant compile, which seems to work. I then zip the folder manually using java's zip utility and rename it to .apk. I am guessing this is the wrong way to do this.
Can anyone show me how to build an Android library project using ant?
I then assumed that perhaps libraries do not get build with release/debug
Correct.
I am guessing this is the wrong way to do this.
Also correct.
Can anyone show me how to build an Android library project using ant?
You typically do not build an Android library project. You build other projects that reference the Android library project. Creating projects that reference the library project, for use with Ant, is covered in the Android documentation. More information about the role of Android library projects can also be found in the Android documentation.
I had the same trouble with a target "nodeps" that was not known by Ant when building a project that was referencing a library. I added a fake target "nodeps", then I get the target "release" unknown. Wrong way.
Solution : in my referenced library directory, I run the command android update project -p . that created the build.xml compatible with Ant build.
