Cannot build project because of error in Android studio

i have the following error:
Build gradle file is following:
apply plugin: 'com.android.application'

compile 'com.android.support:recyclerview-v7:23.0.1'
}
// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'
I researched a little bit and i think that the settings in the gradle file are ok.
So how can i solve this problem?

This is because you have conflicted dependencies in your build.gradle. Firebase UI need version 25 of support library but your dependencies is giving it version 23 instead.
If you want to use firebase-ui:1.2.0, you at least need to use support library version 25.1.1. Take a look at firebase-ui 1.2.0 build.gradle.
Then, you also need to use a compatible Firebase/Google Play Service version. For firebase-ui:1.2.0 you need to use Firebase/Google Play service version 10.2.0.
My suggestion is to use the latest configuration. Something like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.bln.smc"
minSdkVersion 18
targetSdkVersion 26
...
}
...
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:26.1.0'
compile 'com.android.support:design:26.1.0'
compile 'com.android.support:recyclerview-v7:26.1.0'
// This is needed for firebase UI
compile 'com.android.support:support-v4:26.1.0'
compile 'com.android.support:customtabs:26.1.0'
compile 'com.android.support:cardview-v7:26.1.0'
compile 'com.google.firebase:firebase-core:11.4.2'
compile 'com.google.firebase:firebase-database:11.4.2'
compile 'com.google.firebase:firebase-storage:11.4.2'
compile 'com.google.firebase:firebase-crash:11.4.2'
compile 'com.google.firebase:firebase-auth:11.4.2'
compile 'com.google.firebase:firebase-messaging:11.4.2'
compile 'com.firebaseui:firebase-ui:3.1.0'
compile 'com.squareup.picasso:picasso:2.5.2'
}
// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'

Failed to resolve com.firebaseui:firebase-ui:0.5.3

I am new to Android-studio and Firebase.
I am trying to add Firebase UI dependency to my android project and ultimately plan to use FireBase facebook authentication UI.
But I get this message every time I try to sync.
Failed to resolve com.firebaseui:firebase-ui:0.5.3
I checked this link to see the versions but everything looked fine.
This is how my build.gradle looks like:
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "com.example.rohintak.firebasepractice"
minSdkVersion 15
targetSdkVersion 24
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false

}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
// FirebaseUI Database only
//compile 'com.firebaseui:firebase-ui-database:0.5.3'
// FirebaseUI Auth only

compile 'com.google.firebase:firebase-auth:9.4.0'
compile 'com.google.firebase:firebase-core:9.4.0'
compile 'com.google.firebase:firebase-database:9.4.0'
compile 'com.google.android.gms:play-services-auth:9.4.0'
compile 'com.firebaseui:firebase-ui:0.5.3'
compile 'com.firebase:firebase-client-android:2.3.1'
}
apply plugin: 'com.google.gms.google-services'

You're including different versions of the Firebase SDK and FirebaseUI. That won't work.
Cleaned up dependencies:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.google.firebase:firebase-auth:9.4.0'

compile 'com.google.firebase:firebase-database:9.4.0'
compile 'com.google.android.gms:play-services-auth:9.4.0'
compile 'com.firebaseui:firebase-ui-auth:0.5.3'
}

"Method references in a .dex file cannot exceed 64K" after changing build.gradle

I'm getting that error that says I have too many method references:
Error:The number of method references in a .dex file cannot exceed 64K.
It all started when I tried to change my targetSdkVersion to 24 and minSdkVersion to a lower sdk (19) via the gradle app file. That led me to having to change some values throughout the file like
compile 'com.android.support:appcompat-v7:23.0.0'
to
compile 'com.android.support:appcompat-v7:24.1.1'
I've read that people get this error when they have the wrong values in build.gradle. Here was my original build.gradle before the changes:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.delbridge.seth.alarm"
minSdkVersion 23
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
debug {
debuggable true
}
}
}
Any thoughts as to what's causing this?
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.mcxiaoke.volley:library-aar:1.0.0'
compile 'org.jsoup:jsoup:1.9.2'
compile 'org.jdeferred:jdeferred-android-aar:1.2.4'
compile 'com.google.android.gms:play-services-appindexing:9.0.2'
compile 'com.google.android.gms:play-services:9.0.2'
compile 'com.android.support:support-v4:23.0.0'
compile 'com.android.support:design:23.0.0'
compile 'com.android.support:cardview-v7:23.0.+'
compile 'com.android.support:recyclerview-v7:23.0.+'
compile 'com.google.firebase:firebase-ads:9.0.2'
}
apply plugin: 'com.google.gms.google-services'
And here is my build.gradle currently:
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.delbridge.seth.alarm"
minSdkVersion 19
targetSdkVersion 24
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
debuggable true
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.1.1'
compile 'com.mcxiaoke.volley:library-aar:1.0.0'
compile 'org.jsoup:jsoup:1.9.2'
compile 'org.jdeferred:jdeferred-android-aar:1.2.4'
compile 'com.google.android.gms:play-services-appindexing:9.4.0'
compile 'com.google.android.gms:play-services:9.4.0'
compile 'com.google.firebase:firebase-ads:9.4.0'
compile 'com.google.android.gms:play-services-ads:9.4.0'
compile 'com.google.android.gms:play-services-auth:9.4.0'
compile 'com.google.android.gms:play-services-gcm:9.4.0'
compile 'com.android.support:support-v4:24.1.1'
compile 'com.android.support:design:24.1.1'
compile 'com.android.support:cardview-v7:24.1.1'
compile 'com.android.support:recyclerview-v7:24.1.1'
}
apply plugin: 'com.google.gms.google-services'

You're unnecessarily including all of Google Play Services with this line:
compile 'com.google.android.gms:play-services:9.4.0'
So, remove that line and leave the ones that include the individual components:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.1.1'
compile 'com.mcxiaoke.volley:library-aar:1.0.0'
compile 'org.jsoup:jsoup:1.9.2'
compile 'org.jdeferred:jdeferred-android-aar:1.2.4'
compile 'com.google.android.gms:play-services-appindexing:9.4.0'
//remove this line:
//compile 'com.google.android.gms:play-services:9.4.0'
compile 'com.google.firebase:firebase-ads:9.4.0'
compile 'com.google.android.gms:play-services-ads:9.4.0'
compile 'com.google.android.gms:play-services-auth:9.4.0'
compile 'com.google.android.gms:play-services-gcm:9.4.0'
compile 'com.android.support:support-v4:24.1.1'
compile 'com.android.support:design:24.1.1'
compile 'com.android.support:cardview-v7:24.1.1'
compile 'com.android.support:recyclerview-v7:24.1.1'
}
Note:
If the above solution does not solve your issue, then you will need to enable multidex.

try this in your build.gradle file:
android {
compileSdkVersion 22
buildToolsVersion "23.0.0"
defaultConfig {
minSdkVersion 14 //lower than 14 doesn't support multidex
targetSdkVersion 22
// Enabling multidex support.
multiDexEnabled true
}
}
dependencies {
compile 'com.android.support:multidex:1.0.1'
}
check this page: https://developers.google.com/android/guides/setup
and use needed google play service

How to fix error when i import eclipse to android studio?(as compile-time dependency to build.gradle)

when i import project eclipse to android studio. It make error about compile. I want to try fix follow: How to add Apache HTTP API (legacy) as compile-time dependency to build.grade for Android M? But it's not working. please help me!

compile files('libs/mail.jar')
compile files('libs/universal-image-loader-1.9.3.jar')
}

You should remove
compile fileTree(dir: 'libs', include: ['*.jar'])
because it will still compile the library (and all other jars in libs folder), as apparently it is not deleted from libs folder.
After this change, commenting out
//compile files('libs/httpclient-4.0.1.jar')
will really work as you expect :)

No class found exception com.squareup.okhttp.logging.HttpLoggingInterceptor

Even after adding the dependencies and importing the class I am getting java.lang.NoClassDefFoundError: com.squareup.okhttp.logging.HttpLoggingInterceptor.
Can anyone please help?

In my case, I found that the versions of the okhttp3 and okhttp3:logging-interceptor dependencies needed to exactly match. So for example:
...
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.squareup.okhttp3:okhttp:3.4.1'
compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'
...

Could be a compatibility problem with retrofit.
Try with :
implementation 'com.squareup.okhttp:logging-interceptor:2.5.0'

App crash on HttpLoggingInterceptor

Also it can be connected with multidex true option in your build.gradle (yes, seems like some devices have problems with multidex apps (read, Samsung))
If this is your case, switch this flag off and rebuild your project. Consider using
minifyEnabled true
shrinkResources true
to reduce your apk size. If it is still too large, that's really weird and bad news, but there are some techniques to put your apk on diet.
