I am beginner to android studio and I am trying to import a remote dependency for a library of DatePickerDialog (link for its github) but the import doesn't work for me.
I tried to import it by the Group Id (com.github.wdullaer) and Artifact Name (MaterialDateTimePicker) as it shows in the ProjectStructure/dependencies
I tried - import com.github.wdullaer.MaterialDateTimePicker
I also tried - import com.wdullaer.MaterialDateTimePicker
and more but the import does not work
but
here is my gradle:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
mavenCentral()
maven { url 'https://jitpack.io' }
}
dependencies {
classpath "com.android.tools.build:gradle:7.0.4"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.10"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
and here is the DateTimePicker implementation:
plugins {
id 'com.android.application'
id 'kotlin-android'
}
android {
compileSdk 32
defaultConfig {
applicationId "com.example.speedq"
minSdk 21
targetSdk 32
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
buildFeatures {
viewBinding true
}
}
dependencies {
implementation 'com.github.wdullaer:MaterialDateTimePicker:v4.2.3' // this is the implementation I cant import
}
if any one knows how can I import it it will be very helpful
that is wrong:
implementation 'com.github.wdullaer:MaterialDateTimePicker:v4.2.3'
first of all dont use v near version, so just remove it
also you got wrong path, read again guide - you should use this:
implementation 'com.wdullaer:materialdatetimepicker:4.2.3'

I got this fatal error , when I was trying to import opencv module to my project.
Even Gradle sync is finished successfully,
I have also tried invalidate cache and restart but it does not solved anything.
And also went through some stackoverflow's solutions that too didn't work.
please help me finding the solution.

A problem occurred evaluating settings 'MyApplication'.
Could not find method dependencyResolutionManagement() for arguments [settings_5pc4jcjs87c9dkfx5manehm0u$_run_closure1#69c68d91] on settings 'MyApplication' of type org.gradle.initialization.DefaultSettings.
gradle problem is too difficult for novice like me. Is there any solution ?

If i synch the project all looks good but when i try to compile then the error happens. As you can see i haven't include any dependency to the project yet.
Maybe some of you have faced with this problem before and have a solution :)
Of course the error will occur. The error does not occur in sync since there is nothing wrong with the added dependencies. Everything is downloaded and works fine. When you try to compile, it doesn't because you have not added the compose compiler dependency. How would it compile when the compiler itself is missing?
Create a dummy project using the studio templates and copy the dependencies from there.

I am working through Google's Android developer codelab for the the unscramble app. I am trying to initialize my variable wordsList to be an empty mutable list of strings with:
private var wordsList: MutableList<String> = mutableListOf()
However, during my debugging process, I see that the value of wordsList is null and not an empty list like []. I tested the code in kotlin playground and it should be []. I attached a screenshot of what android studio is showing me. What am I doing wrong, why am I not seeing the expected behavior?
Here is the gradle file for my project:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext.kotlin_version = "1.4.21"
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
and the gradle file for my app
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-kapt'
}
android {
compileSdkVersion 30
buildToolsVersion "30.0.2"
defaultConfig {

}
}
compileOptions {

targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
buildFeatures {
viewBinding = true
}
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'androidx.core:core-ktx:1.3.2'

}
Referring to Kotlin docs:
During an instance initialization, the initializer blocks are executed
in the same order as they appear in the class body, interleaved with
the property initializers
So, your breakpoint is probably hit from the upper init { } block when wordsList is not initialized yet. You may choose to initialize your variable before calling getNextWord() or just move this init { } block down so it is executed when all your properties are already initialized.
I'm getting really frustrated with this. I've managed to make the google play services available in Android Studio but now I can't instantiate an AdView class. I can import import com.google.android.gms.ads.*; no errors there, it just says Unused import but when I try to create an AdView class I get a cannot find symbol error. It also doesn't find com.google.android.gms.ads.AdView or any other class inside that package for that matter.
I tried cleaning/re-building/restarting the IDE but nothing worked so far.
Here's my build.gradle file:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.7.+'
}
}
apply plugin: 'android'
repositories {
mavenCentral()
}
android {
compileSdkVersion 19
buildToolsVersion '19.0.1'
defaultConfig {
minSdkVersion 15
targetSdkVersion 19
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
buildTypes {
release {
runProguard true
proguardFile getDefaultProguardFile('proguard-android.txt')
}
}
productFlavors {
defaultFlavor {
proguardFile 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.google.android.gms:play-services:4.0.30'
compile files('libs/libGoogleAnalyticsServices.jar')
}
Fixed
