kotlinlang #android

i'm getting an internal KAPT error when compiling a dagger ViewModelModule with the @Binds @IntoMap @ViewModuleKey annotations. Trying the convert the Architecture Compentents githubbrowser sample. Any advice, or should I rewrite to use constructor injection?

hi there, I think I'm facing this issue? is there any progress on it? is it an issue? https://youtrack.jetbrains.com/issue/KT-16084

it relates:

Inline function, Lambda and Proguard: I cannot specify the case. If you write 3 depth inline or SAM function, you may face error while obfuscation of proguard. Especially, let run apply also

is there any work around, other than refactoring the code?

Hi guys, I'm having another issue while running Espresso tests in my ec2 instance:

Copy code

> Task :app:connectedDevDebugAndroidTest
12:59:37 V/ddms: execute: running am get-config
12:59:42 V/ddms: execute 'am get-config' on '0.0.0.0:32818' : EOF hit. Read: -1
12:59:42 V/ddms: execute: returning

12:59:51 V/ddms: execute: returning

I have a docker container running an emulator at 0.0.0.0:32818. The project compiles properly, yet it can't for some reason upload the file. Any ideas? Thanks

I am really confused by

kotlinx.android.extensions.LayoutContainer

- the property it defines is called

containerView

but it is used for the content of a `ViewHolder`; I think it should be called

contentView

containedView

- not

container

because “container” in English means the holder. Am I misunderstanding it or is it poorly named?

Hello everybody, I'm trying to run my instrumented tests with Firebase Test Lab, yet getting this error:

Copy code

Matrix [matrix-6a9q91kg6iw8a] failed during validation: The test APK does not contain the test runner class specified by the user or the manifest file. The test runner class name may be incorrect, or the class may be mislocated in the app APK..

tests are running well locally as well as in jenkins. I'm running:

Copy code

gcloud firebase test android run \
                               --type instrumentation \
                               --app app-dev-debug.apk \
                               --test app-dev-debug-androidTest.apk \
                               --device model=Nexus6,version=21,locale=en,orientation=portrait \
                               --timeout 90s

In my build.gradle:

Copy code

...
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
...

Any idea?

What does this indicate? It seems like it’s undesirable, but I have no idea how to make it go away so that I can set the compiler settings… (to include ExperimentalUnsignedTypes support)

When using backticks to have spaces in symbols the library becomes unusable on Android:

Caused by: com.android.tools.r8.utils.AbortException: Error: Field name 'lowercase words' cannot be represented in dex format.

Can that be fixed by the Kotlin compiler somehow or do we really have to avoid spaces altogether?

03/15/2019, 2:31 AM

avoid

TLDR Annotation processing fails with kapt

./gradlew clean test assemble

-> ✅

./gradlew clean && ./gradlew test && ./gradlew assemble

-> ❌ I am switching annotation processing to kapt. Everything works fine in android studio but the annotation processing fails on jenkins. All I can see is

Task :app:compileDebugJavaWithJavac FAILED

followed by

error: cannot find symbol

in all dagger components. Jenkins pipeline has three steps. 1. Clean ->

./gradlew clean

2. Test ->

./gradlew test

3. Assemble ->

./gradlew assemble

Which is equivalent to

./gradlew clean && ./gradlew test && ./gradlew assemble

If instead of three separate steps if I run

./gradlew clean test assemble

I don’t get any errors So far I have enabled caching, but it seems to have no effect

Copy code

kapt {
    useBuildCache = true
}

Copy code

fun <T: View> LayoutInflater.inflateAs(@LayoutRes resource: Int, root: ViewGroup?, attachToRoot: Boolean) = inflate(resource, root, attachToRoot) as T

Paul Woitaschek

03/15/2019, 11:23 AM

Because inflate returns View and not T : View

ghosalmartin

03/15/2019, 11:27 AM

Hmm whats odd at the original call site I can write effectively

view as CustomView

with no unchecked cast

cbruegg

03/15/2019, 11:55 AM

Because

CustomView

is probably not a generic parameter

cbruegg

03/15/2019, 11:56 AM

Generic parameters are erased at runtime. But you can probably write

inline fun <reified T: View> LayoutInflater.inflateAs

cbruegg

03/15/2019, 11:56 AM

That way the function will be inlined and the cast will be checked

ghosalmartin

03/15/2019, 2:25 PM

Ahh thats the one, completely forgot about that. Thanks 🙂

I'm curious how others deal with fragments that are put to the backstack (due to navigation). Specifically fragments containing a grid of images. Do you hold a reference to the adapter or do you release it in onDestroyView? I.e. do you create a new adapter for every view or not? I'm afraid that not releasing the adapter is retaining all the ViewHolders and thus all the images when the fragment is in the backstack.
