How to install lettuce library on Android Studio?

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.

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/android/gms/common/internal/zzbq Nearby Place App

I made a app find nearby place but i get this error
> Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.android.gms.common.internal.zzbq" on path: DexPathList[[zip file "/data/app/vapelit.unikomapps.com.vapelitfinal-1/base.apk"
Here my gradle
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
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'
compile 'com.synnapps:carouselview:0.1.5'

implementation 'com.google.android.gms:play-services-maps:15.0.0'
implementation 'com.google.android.gms:play-services-auth:15.0.0'
implementation 'com.google.android.gms:play-services-location:15.0.0'
}## Heading ##

You need to implement this :
implementation 'com.google.android.gms:play-services-maps:16.0.0'
implementation 'com.google.android.gms:play-services-auth:16.0.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
and add this in your gradle :
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '28.0.0'
}
}
}
}
and in your gradle you have to delete this :
implementation 'com.google.android.gms:play-services-maps:15.0.0'
and keep only this:
implementation 'com.google.android.gms:play-services-maps:16.0.0'
Happy Coding ;)

#Agam
In your gradle code your are using google map library with different version. So remove old version library and make sure you are using same version of all google play service library which are related to each other.
Try to update below line in your gradle file and remove google play service library which include all google play services file under one gradle library. For mode details about google play service visit on Google Play Service Version with Table 1:
implementation 'com.synnapps:carouselview:0.1.5'
implementation 'com.android.support:multidex:1.0.3'
//implementation 'com.google.android.gms:play-services:12.0.1'
implementation 'com.google.android.gms:play-services-maps:16.0.0'
implementation 'com.google.android.gms:play-services-auth:16.0.1'
implementation 'com.google.android.gms:play-services-location:16.0.0'
I hope you will resolve your problem.

Failed to find style 'chipIconSize' in current theme

I wished to make floating label type of edit text. So I added this under dependencies:
implementation 'com.android.support:design:28.0.0'
Now, I am getting this error under Render Problem:
Render Problem
Failed to find style 'chipIconSize' in current theme
The above error is shown in the xml preview.
This is the dependency section in build gradle(module app) :
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
//noinspection GradleCompatible
implementation 'com.google.firebase:firebase-database:16.0.3'
implementation 'com.google.android.gms:play-services-location:16.0.0'
// implementation 'com.google.firebase:firebase-core:16.0.4'
implementation 'com.google.firebase:firebase-messaging:17.3.3'
implementation 'com.google.firebase:firebase-auth:16.0.4'
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:cardview-v7:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
}
The logcat shows the following error and warning under Java compiler:
The app gradle file must have a dependency on com.google.firebase:firebase-core for Firebase services to work as intended.
java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2Exception: AAPT2 error: check logs for details
How can I resolve the error?

The app gradle file must have a dependency on
com.google.firebase:firebase-core for Firebase services to work as
intended.
Add :
implementation 'com.google.firebase:firebase-core:16.0.4'
To your build.gradle dependencies.
For the :
Failed to find style 'chipIconSize' in current theme
It seems liek you'll need to add:
implementation 'com.google.android.material:material:1.0.0'
To support that attribute from material design or simply, remove it.

How to import javax.annotation.Nullable?

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'
}

Program type already present com.google.gson.FieldAttributes

My android app refuses to build with the following error:
Program type already present: com.google.gson.FieldAttributes
Message{kind=ERROR, text=Program type already present: com.google.gson.FieldAttributes, sources=[Unknown source file], tool name=Optional.of(D8)}

transitive = true
}
implementation('com.crashlytics.sdk.android:crashlytics:2.9.4#aar') {

}}
It probably started to happen when I added com.github.GrenderG:Prefs dependency

Add this line to build.gradle file.
configurations {
all*.exclude group: 'com.google.code.gson'
}

After 3 hours of googling around I finnaly found an Answer:
GPDR compilance library caused the problem
implementation ('com.google.android.ads.consent:consent-library:1.0.6') {
exclude module: 'gson'
}

add this code to your build.gradle(app) -
dependencies {
configurations {
all*.exclude group: 'com.google.code.gson'
}
This should solve your problem.

Add Dependency to build.gradle file
implementation 'com.google.code.gson:gson:2.8.2'
