I have a module called "Common" as library, this module has few dependencies like: com.badlogicgames.gdx, com.squareup.wire etc. And it works fine, I use them inside of this module.
And I have another module called "Tracking", where in the gradle I have:
dependencies {
compile project(':Common')
}
And if I try there to import any public class of module "Common", it works fine, but if I try to import any class of library com.badlogicgames.gdxor com.squareup.wire, it says me "Cannot resolve symbol ..." and hightlight it red. And no code autocompleting for such classes.
However the project compiles and starts on the device without errors.
Has somebody any idea? I tried "clean and rebuild" for project, "invalidate cashes and restart" for Android Studio. Nothing helps.
in the module common you need to declare those transitive dependencies as api to expose them to other modules:
e.g. common/build.gradle:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
api 'com.squareup.wire'
}
https://jeroenmols.com/blog/2017/06/14/androidstudio3/
Solution
Change compile to api
dependencies {
api project(':Common')
}
Reason
Because compile is deprecated, so it is been treated as implementation.
FYI compile and api (new keyword for compile) are same in which all internal modules are visible.
But new gradle project having compile keyword are treated as implementation. and in implementation internal modules are not visible to main project.
Suggestion
You should declare dependency in your gradle because it is not good to make leak of internal modules.

I am working on Android ViewModel architecture component but I am getting the above mentioned error when trying to initialize a ViewModel in an AppCompatActivity.
import android.arch.lifecycle.ViewModelProviders;
ViewModelProviders.of(this).get(CounterViewModel.class);
There are a few questions and articles related to this, and they pointed towards adding the lifecycle:extensions and lifecycle:viewmodel dependencies in the app gradle file, but I am still getting the error.
implementation "android.arch.lifecycle:extensions:1.1.1"
implementation "android.arch.lifecycle:viewmodel:1.1.1"
annotationProcessor "android.arch.lifecycle:compiler:1.1.1"
The package android.arch.lifecycle does not contain the class ViewModelProviders and it only has ViewModelProvider class.
What else needs to be added to access the ViewModelProviders class?
Edit :
Dependencies in app/build.gradle:
dependencies {
implementation project(':lifecycle')
implementation project(':base')
implementation "android.arch.lifecycle:extensions:1.1.1"
implementation "android.arch.lifecycle:viewmodel:1.1.1"
annotationProcessor "android.arch.lifecycle:compiler:1.1.1"
}
android.arch.lifecycle:extensions:1.1.1 definitely has android.arch.lifecycle.ViewModelProviders. You can see it in Android Studio, if you open the "External Libraries" portion of the project tree and examine the library contents:
Some possible reasons for not finding the import include:
You have implementation "android.arch.lifecycle:extensions:1.1.1" in the wrong place (it should be in the dependencies closure of the module's build.gradle file, such as app/build.gradle)
You did not sync Android Studio with the Gradle build files (you are normally prompted to do this, but you can do it manually from File > Sync Project with Gradle Files from the Android Studio main menu)
You do not need both lifecycle:extensions and lifecycle:viewmodel in your build.gradle file, remove
implementation "android.arch.lifecycle:viewmodel:1.1.1"
and it should be fine now. Also, you may want to migrate to AndroidX and use the 2.0.0 versions of the library.
ViewModelProviders is now deprecated. Use ViewModelProvider instead.
If you are configuring in libary, you can modify the implementation to api
I have an Android project in which I have been using ACRA 4.6.0 with a static jar file, all working fine. I have tried to change this to use the latest ACRA by the maven dependency in build.gradle:
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
testCompile 'junit:junit:4.12'
compile 'ch.acra:acra:4.8.5'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
}
in my build.gradle. However this causes the build to fail with errors like:
CJApp.java:13: error: cannot find symbol
import org.acra.ACRAConfiguration;
^
symbol: class ACRAConfiguration
location: package org.acra
So far as I can tell gradle is not downloading anything for acra. I have tried adding mavenCentral() to the repositories list with no effect.
What else do I need to do, and is there any way of determining just what gradle has downloaded?
Are you sure that the class org.acra.ACRAConfiguration is included in the new version: acra:4.8.5 which you're suddenly linking to? If not, this is a simple matter of incompatibility. In that case, it should be resolved if you step the version back to 4.6.0.
Have you checked that the build downloads the file from Maven Central? This should be clearly visible when giving gradle the -i flag - it will print every URL as it downloads them.
ACRAConfiguration has moved to org.acra.config. Just adjust your import.
In my build gradle file I have two dependencies (appcompat-v7 and design) and then whatever externar jar files I add to the project
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.android.support:design:22.2.1'
}
Is it normal to find in the project libraries (Project structure -> Libraries) the external jar files, appcompat-v7, design-22.2.1, support-v4 and support-annotations-22.2.1, I don't understand why the two last ones are being added, I think they're the cause of another issue I'm having (dexDebug).
Would anyone know if that is normal ?
Thanks
Running ./gradlew -q app:dependencies shows that com.android.support:appcompat-v7 depends on com.android.support:support-v4, so that is why it is pulled in. You will have to find a separate solution for your dex debug issue.
So, I managed to create an Android library component and publish it on Maven Central. But when I'm trying to use it as a dependency in a new project, Android Studio can't seem to find the classes.
build.gradle for the app module:
repositories {
mavenCentral()
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'no.hyper:libdateintervalpicker:1.0.0' //this is the one I want to use
}
This part seems to work, at least I get no sync errors. However, when trying to access to package and classes from my MainActivity, Android Studio can't find them and gives me "cannot resolve symbol" message.
I have tried downloading the classes.jar from the archive directly from Maven Central, and they are indeed in the package.
Other dependencies seem to appear in the /build/intermediates/exploded-aar folder after syncing, but that does not happen to my library.
I use Android Studio 1.0.2 on OSX 10.9.5 (Mavericks)
Any suggestions?
Looking in your pom, it states <packaging>aar.asc</packaging>. It should be aar instead.
Oh, and the answer to actually being able to use the library, was to add #aar to the dependency so that it now reads
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'no.hyper:libdateintervalpicker:1.0.0#aar' //note the magic #aar
}
Edit:
Removing the block
configurations {
archives {
extendsFrom configurations.default
}
}
makes Gradle generate the pom with the correct packaging entry, and thus makes it possible to reference the dependency without the #aar suffix
I Added a External Library to my project by following
this method. and tried this method too this method too.
Gradle build got Finished and i got this line added to my build.gradle
compile 'com.github.castorflex.smoothprogressbar:library-circular:1.0.1'
Now i am trying to import this library in my class. But i can't do this. I took a look at the files and they are located in the build directory under the exploded-aar. so i added #aar to the compile line. Still there are no changes.
How can i import this library to my class or where i am going wrong?
Thanks in Advance
Well, you don't need to download anything or point your dependency to a file.
This dependency, as most of the dependencies you use, can automatically fetched from JCenter, biggest repository for Java and Android components.
All you need to do is:
Add JCenter as your dependencies repository.
Declare that you need the library-circular dependency. This can be found and copy/pasted from the file icon in particular package/version in JCenter.
Resync your Android Studio project with your Gradle build file. This is the 'sync' button in Gradle pane in Android Studio.
Here's what your build.gradle should include:
repositories {
jcenter()
}
dependencies {
compile(group: 'com.github.castorflex.smoothprogressbar', name: 'library-circular', version: '1.0.1', ext: 'aar')
}
in build. gradle put following code
dependencies {
compile fileTree (dir: 'libs', include: ['*.jar'])
}
Did you add the dependencies?
You can do so in the following way -
dependencies {
compile files('insert ParentFolder/external_library_name with the extension here')
}
Add it to build.gradle based in the app folder
1.Put the jar file into the libs folder.
2.Right click it and hit 'Add as library'.
3.Ensure that compile files('libs/abcdef.jar') is in your build.gradle file and Finally add the dependencies.
Eg.
dependencies {
compile fileTree(dir: '../jar', include: '*.jar')
compile project(':pull-to-refresh')
compile files('libraries/abcdef.jar')
}
Hope this helps :)
