Resource linking fails on lStar with error

I'm working on a android Native application. My Android builds began to fail without any changes.
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':etndoorcontrol:processHesuan_faceDebugResources'.
> Android resource linking failed
C:\Users\xqf\.gradle\caches\transforms-2\files-2.1\fe7b90aa462d9a2e04dd8216aa450a51\res\values\values.xml:2422:5-2449:25: AAPT: error: resource android:attr/lStar not found.
error: failed linking references.
Then I tried 2 solutions
//soultion 1.
configurations.all {
resolutionStrategy {
// Java language implementation
force "androidx.core:core:1.6.0"
// Kotlin
force "androidx.core:core-ktx:1.6.0"
}
}
After I add this to app/build.gradle, the app can build correct.but after I install the apk and run .there is a new problem.

After this, I tried the other solution, as below:
ext{
androidX = 1.6.0
}
but this is not working for me.

axel8888 thank your sir, yes, I have solved this problem. yes, you are right , when I try solution one again
configurations.all {
resolutionStrategy {
// Java language implementation
force "androidx.core:core:1.6.0"
// Kotlin
force "androidx.core:core-ktx:1.6.0"
}
}
and as you the problem is now in
androidx.appcompat:appcompat:1.4.0-alpha
so I checked the gradle dependencies, yes , even I used
androidx.appcompat:appcompat:1.3.1
but my project shows the version is 1.4.0-alpha. here is my solution
configurations.all {
resolutionStrategy.eachDependency { details ->
def requested = details.requested
if (requested.group == "androidx.appcompat") {
if (requested.name == "appcompat") {
details.useVersion "1.3.1"
}
}
}
}
and it worked, now my project can build and run correctly, thank you, sir!

Obveiously the problem is now in androidx.appcompat:appcompat:1.4.0-alpha. If your UI use Toolbar, you will get the MenuHost not found crash.BUT, evenif I use resolutionStrategy to force 'androidx.appcompat:appcompat:1.3.1', dependency still make it toandroidx.appcompat:appcompat:{strictly 1.4.0-beta01}
It still confuse me a lot.
SOLVED -- someone write a update code for appcompat before... now it can force to 1.3.1 and solve the problem

change
implementation 'androidx.appcompat:appcompat:1.4.0'
to
implementation 'androidx.appcompat:appcompat:1.3.1'
that's it

implementation 'androidx.appcompat:appcompat:1.4.1'
was causing the problem, going back to 1.3.1 worked.
implementation 'androidx.appcompat:appcompat:1.3.1'
ill update once I get an official solution.

Android java.lang.ClassNotFoundException: Didn't find class

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.

Jacoco: IllegalStateException: Can't add different class with same name

I am trying to generate Jacoco XML reports for this Android project. I am using the gradle-android-junit-jacoco-plugin version 0.16.0 (latest as of today).
When I run the jacocoTestReportMerged task it fails with the following error:

I started configuring exclude rules such as ...
junitJacoco {
excludes = [
"**/XmlPullParsers.*"
]
}
... but then the task fails at the next file - so this does not seem to be the correct way.
I also tried 0.17.0-SNAPSHOT and version prior to 0.16.0, without success though. Gradle 6.3 is used in this project.
How can I configure the Gradle plugin for my project?

Problems getting started with Chirp SDKs for Android

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.chirpsdk.ChirpSDK.<init>(Unknown Source:8)
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'

Instrumentation tests fail on virtual devices

I am using Jake Wharton's Double Espresso library for setting up Instrumentation tests in my app. The tests run fine on my phone but crash on any virtual device (I tried an emulator and Genymotion device).
The error I get is the IllegalAccessError that has been reported [previously]((Instrumentation run failed due to 'java.lang.IllegalAccessError'. Gradle + Espresso). However, what puzzles me is why it only happens on virtual devices. The setup should be fine if it's able to run on physical devices.
The stacktrace includes errors all over the place but the one reported as fatal is :
java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:595)
at dalvik.system.NativeStart.main(Native Method)
In any case, I tried excluding all the libraries that could have possible clashes but I still can't get it to work. Does anyone have any ideas on what the issue might be or even how to troubleshoot ?
The problem does seem to be related to daggger which is being used in the app as well. MyApp:32 points to the line where ObjectGraph is created and the following two lines are in the stacktrace.
W/dalvikvm﹕ Class resolved by unexpected DEX: Lcom/myApp/MyApp;(0xa4df7388):0x97542000 ref [Ldagger/ObjectGraph;] Ldagger/ObjectGraph;(0xa4df7388):0x97add000
W/dalvikvm﹕ (Lcom/myApp/MyApp; had used a different Ldagger/ObjectGraph; during pre-verification)
**UPDATE: ** The issue is likely related to the Dalvik VM on the virtual devices. My phone is set to ART and similar issues with Dalvik have been reported previously. It should be fixed by adding the following:
androidTestCompile('com.jakewharton.espresso:espresso:1.1-r3') {
exclude group: 'com.squareup.dagger'
}
as per the library page but that doesn't seem to help.

The issue was actually caused by the espresso-support library. I needed to add com.squareup.dagger as an exclusion there too while I was only adding exclusions to the other library.
androidTestCompile('com.jakewharton.espresso:espresso:1.1-r3') {
exclude group: 'com.squareup.dagger'
}
androidTestCompile ('com.jakewharton.espresso:espresso-support-v4:1.1-r3') {
exclude group: 'com.squareup.dagger' // this goes here too
exclude group: 'com.android.support', module: 'support-v4'
}
