I have found a lot of similar questions, but no one helps me.
I have next problem. I have complete project for Android and I have to export it's functionality to .aar library. First of all I created new project and created new module where put my source project. At this step all things goes well and I get my mylib.aar file in /build/outputs/aar/ folder. Then I created new project to test my mylib.aar, so I created libs folder under my app folder in Android Studio, and in build.gradle file of my test project I added these lines:
repositories {
flatDir {dirs 'libs'}
}
dependencies {
compile(name: 'mylib', ext: 'aar')
}
In manifest file I added declaration of MainActivity from library:
<activity android:name="com.testlib.mylib.MainActivity"
android:label="MainActivity"/>
Android Studio found this file well and I even can watch source code through built-in decompiler. But when I try to start this activity from another activity that isn't placed in my lib I get this error:
3838-3838/com.testapp.testsdkapp E/AndroidRuntime﹕ FATAL EXCEPTION: main

RegisterInBackgroundTask is inner public AsyncTask class declared in my MainActivity in the library. I tried to put mylib.aar in aar folder and declare in build.gradle in other way, but it didn't help me and I get similar error.
If this information is not enough, I'll add required parts of code etc. So please help me, if you know how to solve my problem! Thanks.
import mylib.aar as module in your project and inside dependencies add following line
compile project(':mylib')

I'm a total Android newbie here, so hopefully someone can help me out.
I have an Android library (myLib.aar) that I am including/using in the HelloAR demo app.
Now, I want to use Instacapture within myLib.aar. I followed the instructions on the README:
dependencies {
...
compile "com.github.tarek360:instacapture:2.0.1"
}
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
I also tried downloading, compiling instacapture source, adding the instacapture.aar to my libs dir and modifying my Gradle files:
dependencies{
...
implementation(name:'instacapture', ext:'aar')
}
allprojects {
repositories {
...
flatDir {
dirs 'libs'
}
}
In both cases, I get the following exception:

However, if I add the dependencies to the main HelloAR app (as per the instructions in the README), the issue resolves.
Can someone please explain what is going on, why I'm getting the error, and how to resolve it without having to add the dependencies to the main HelloAR app?
Considering your quote,
I'm a total Android newbie here, so hopefully someone can help me out.
Follow these steps (in android studio) :
Go to build menu.
Clean the project by clicking on clean project.
Build the project by clicking on make project.
This process is known as clean build which is usually done after adding some dependencies.
I have downloaded SDK for Android from
https://developers.chirp.io/downloads
After that I added *.aar library as was explain here:
https://developer.android.com/studio/projects/android-library.html#AddDependency
Hurrah. I can build the project.
Now I want to install the test App on the phone. But the application crashes like this:
E/AndroidRuntime: FATAL EXCEPTION: main
Process: io.chirp.sdkdemoapp, PID: 12979
java.lang.NoClassDefFoundError: Failed resolution of: Lkotlin/jvm/internal/Intrinsics;

at io.chirp.chirpsdk.ChirpSDK.<init>(Unknown Source:8)
at io.chirp.sdkdemoapp.MainActivity.onCreate(MainActivity.java:77)
As I understand it, a problem arose with dependencies when packaging * aar
So I added in build.gradle (marked as Module) dependency for kotlin like:
implementation 'org.jetbrains.kotlin:kotlin-stdlib:1.2.61'
After that my ERROR has changed.
E/AndroidRuntime: FATAL EXCEPTION: main

at io.chirp.sdkdemoapp.MainActivity.onCreate(MainActivity.java:77)
I have wrong paths to io.chirp internal libraries.
What should I do to resolve dependency related errors?
You have to import the okhttp 3.12.x dependency required by the ChirpSDK.
However, you don't need to explicitly import the dependency if you are using the SDK from the maven repository as this will be already included:
implementation 'io.chirp:chirpsdk:3.10.0'
and add the repository in your parent maven file:
repositories {
maven {
url "https://maven.chirp.io/release"
}
}
Thanks Dinu for your answer!
Maven repository doesn't work in my case (proxy issues or something else but this is the topic of another discussion).
The problem with using offline ChirpSDK was solved by adding two dependencies:
implementation 'com.squareup.okhttp3:okhttp:3.12.6'
implementation 'org.jetbrains.kotlin:kotlin-stdlib:1.3.50'
Similar questions have need asked already. But this one seems to be more complicated than previous ones because of changes in compatibility of Android Platforms.

Same code when ran on Devices running Android 7.0 and below, it works perfectly fine.
I tried adding dependency to my project too
implementation "commons-logging:commons-logging:1.2"
Adding this dependency makes the app work in Pixel and Pixel but then it crashes in all other devices with Exception saying
org.apache.commons.logging.impl.LogFactoryImpl does not extend or implement org.apache.commons.logging.LogFactory
I tried doing all the changes in ProGuard already. Here is my proguard configuration
-keep class org.apache.commons.logging.impl.LogFactoryImpl
-keep class org.apache.commons.logging.LogFactory
-keepnames class org.apache.commons.logging.impl.* {*;}
-keepnames class org.apache.commons.logging.*

-keepclassmembers class org.apache.commons.logging.*

-keepnames interface org.apache.commons.logging.*
Still causing the crash.
This issue is related to Amazon AWS SDK - https://github.com/aws/aws-sdk-android/issues/476
Is there any workaround till AWS updates their SDK to fix this issue?
Add this below line in manifest file.
<uses-library android:name ="org.apache.http.legacy" android:required ="false"/>
This is an AWS SDK bug that appears to be solved in version 2.6.30 of the SDK:
Fixed a bug where getting a logger using Apache Commons Logging would
crash starting Android 9.0 (Pie / API Level 28). See pull #521. Now,
Apache Commons Logging would be used if it's being added as a
dependency, otherwise android.util.Log will be used.
to fix this issue I had the dependency
implementation "commons-logging:commons-logging-api:1.1"
in gradle file.
An alternative workaround is to add the commons-logging library as a .jar file to your libs/ folder instead of using implementation. Make sure that implementation fileTree(include: ['*.jar'], dir: 'libs') is in your dependencies.

After configuring account kit sdk as
compile 'com.facebook.android:account-kit-sdk:4.+'
and gradle sync it conflict with com.google.android.gms gradle as mixing versions can lead to runtime crashes and my app crash as
Firebase API initialization failure.

the above error is due to mixing google play services gradle (I think Google play services gradle may be used by Facebook Account Kit SDK) because I have same version for all Google play services gradles.
And one more crash is coming from Facebook Account Kit SDK side as

But after removing
compile 'com.facebook.android:account-kit-sdk:4.+'
my app working without any issue.
But to integrate Facebook Account Kit in my app I have to include above gradle which conflict with google play services.
Totally disappointed, please help.
After upgrading Firebase Gradle as
compile 'com.google.firebase:firebase-messaging:11.6.0'
its not colliding but still gives above RuntimeException from Account Kit SDK.
To fix this you can do something like the following
compile ('com.facebook.android:account-kit-sdk:4.27.0') {
exclude group: 'com.google.android.gms', module: 'play-services-auth-api-phone'
exclude group: 'com.google.android.gms', module: 'play-services-auth'
}
compile 'com.google.android.gms:play-services-auth:11.6.0'
compile 'com.google.firebase:firebase-messaging:11.6.0'
That would remove the stale support gms library from Facebook's SDK and then swap in the same version of the lib that Firebase is using.
Possibly the conflict of libraries can be the reason. See dependencies here;
https://mvnrepository.com/artifact/com.facebook.android/account-kit-sdk/4.27.0
See if you could submit an issue with the facebook to update it.
Or if you need facebook for authentication only, you can use Facebook Android Sdk
What feature/service from firebase r u using , can u pls share the snippet of ur gradle dependencies for the same to better understand the problem here?
For Unable to get provider RuntimeException exception it seems that, Application is not initialized first, Content Providers are initialized before it.
And in Facebook account kit SDK's code it was trying to get my application context.
Now the problem was, I did implement method getApplicationContext() in application class that is getting application shared variable but that variable was setting globally and Facebook Account Kit sdk code getting Null application context.
Solution : setting shared variable in onCreate method instead of setting globally it resolved the problem of Unable to get provider.
And For Mixing issue, Account Kit SDK use 11.0.1 version for play services gradle and in my project I am having 11.0.4 that is actually not the issue because on compile time gradle takes latest gradle but In my project I am not referring below gradle which Facebook Account Kit SDK is using.
compile 'com.google.android.gms:play-services-auth-api-phone:11.0.1'
Solution : I have added above gradle with version 11.0.4 and the mixing gradle issue has been resolved.
compile 'com.google.android.gms:play-services-auth-api-phone:11.0.4'
And as suggested by #astryk if I exclude play-services-auth-api-phone module then gradle mixing error is not showing but it is not including that module becasue in AccountKitActivity on next button click my application crashes as

After I went through the R files that are generated in my application I found out a significant amount of fields that exist in R.txt file in the aar are missing from the generated R.
I've tried building with and without proguard, updating gradle version, I cleaning and rebuilding the project, removing "build" directory manually, adding the aar as a module.
None of these seem to be the problem, the R file is still missing fields.
Thanks for any help, Ilia.
Keep aar file in libs folder. ( as libname.aar )
then in app build.gradle specify following.
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
compile(name:'libname', ext:'aar')
}
and click sync project with gradle files.
Then clean build the project.
