I am not able to use the RecyclerVeiw class even after adding dependencies in build.gradle(Module:app)
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
implementation 'androidx.recyclerview:recyclerview:1.1.0'
}
No need to add any special dependency
Just update android studio and use it
Even though if you want to make it work through adding dependencies add this
//in xml add this
<androidx.recyclerview.widget.RecyclerView>
// in class add this
import androidx.recyclerview.widget.RecyclerView;
no need to add any dependency
//in xml
<androidx.recyclerview.widget.RecyclerView>
// in class
import androidx.recyclerview.widget.RecyclerView;

I have the following in my app build gradle:
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
implementation "com.mapbox.navigation:ui:1.4.0"
implementation 'com.mapbox.mapboxsdk:mapbox-sdk-services:5.8.0'
implementation 'com.mapbox.mapboxsdk:mapbox-android-plugin-locationlayer:0.11.0'}
and have successfully run things such as a map and placing markers down etc. However, when I go to import anything from services, such as import com.mapbox.services.android.navigation.ui.v5.NavigationLauncher; Android Studio cannot find anything. I've tried different versions in case the imports I needed were deprecated but to no avail. Any ideas? All the tutorials and example code in the documentation and third-party all use these imports and I don't really see a way around them.
Thanks!
In the module-level build.gradle file, add the following dependencies:
// in addition to the rest of your build.gradle contents
// you should include the following repository and dependencies
repositories {
mavenCentral()
maven { url 'https://mapbox.bintray.com/mapbox' }
}
dependencies {
implementation 'com.mapbox.mapboxsdk:mapbox-android-navigation-ui:0.42.6'
}
I have created a custom Class which extends ImageView. It was working perfectly fine until AndroidX shows up.
Here, the java code
import android.content.Context;
import android.graphics.BitmapFactory;
import android.util.Base64;
import android.widget.RelativeLayout;
import androidx.appcompat.widget.AppCompatImageView;
public class CloseView extends AppCompatImageView {
public CloseView(Context context) {
super(context);
init();
}
...
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
Android shows 2 errors for this file
error: cannot find symbol class AppCompatImageView
error: package androidx.appcompat.widget does not exist
Has anyone able to fix this issue?
You should completely migrate to AndroidX to use its classes
Enable AndroidX in Gradle settings:
android.useAndroidX=true
android.enableJetifier=true
Replace dependencies
implementation 'androidx.appcompat:appcompat:1.0.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
instead of
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
See: https://developer.android.com/jetpack/androidx/migrate
Edit:
AndroidX is the newest replacement to all the previous numbered support libraries. Read more about it here before you start using it.
How to install lettuce library on Android studio in Gradle files ?
https://lettuce.io
is there any solution to compile the library ?
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0’
}
In the lettuce's getting started section there is a section called For Gradle Users on how to add the library from gradle. I think just adding:
implementation 'io.lettuce:lettuce-core:5.1.3.RELEASE'
would work. You must check if you must adjust your current dependencies and/or modify your proguard rules.
Hope I helped.
I'm trying to import the following classes for my media player, but my app does not recognize them:
import android.support.v4.media.MediaMetadataCompat;
import android.support.v4.media.session.MediaControllerCompat;
import android.support.v4.media.session.MediaSessionCompat;
import android.support.v7.app.NotificationCompat;
I've tried as others suggested (File->Invalidate Caches/restart), but the error remains.
gradle:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0-rc02'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.support:recyclerview-v7:28.0.0-rc02'
implementation 'com.android.support:cardview-v7:28.0.0-rc02'
implementation 'com.android.support:design:28.0.0-rc02'
implementation group: 'com.google.code.gson', name: 'gson', version: '2.7', changing: true
}
Add this dependencies to your gradle ;
com.android.support:support-v4:YOUR_VERSION
in long way ;
Project Structure --> Dependencies --> Click Plus sign -> Go to
"Library dependency"
Select which support library "support-v4
(com.android.support:support-v4:YOUR_VERSION)"
Be sure about Android Support Library has been added to your
dependencies.
Rebuild and work it.
Just Add Dependencies in our Gradle File
dependencies {
......
implementation 'com.android.support:support-v4:VERSION'
.....
}
Ex
dependencies {
......
implementation 'com.android.support:support-v4:27.0.1'
.....
}
For android x based projects, add this
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
I use Android Studio 3.x and Gradle build script.
How can I import javax.annotation.* packages?
Here is my Gradle depedencies example.
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.android.support:support-v4:27.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
implementation 'com.google.code.findbugs:jsr305:3.0.2'
You can use the following if You olny need annotation feature
implementation "javax.annotation:jsr250-api:1.0"
But need to very careful while using this, Reason being these classes are provided by multiple libraries like
implementation 'com.google.code.findbugs:jsr305:3.0.2'
implementation 'javax.inject:javax.inject:1'
implementation 'org.jetbrains.kotlin:kotlin-reflect:$versions.kotlin'
If You are using them already either You don't include that one or use exclude with them to avoid any build errors.
implementation (org.jetbrains.kotlin:kotlin-reflect:$versions.kotlin){
exclude module: 'jsr305'
exclude module: 'jsr250'
}
