Problem authenticating with gmail on Android - java

Cannot authenticate with Google on Android. Android Studio shows these errors:
The following classes could not be instantiated:
com.google.android.gms.common.SignInButton
Here is my XML
<com.google.android.gms.common.SignInButton
android:id="#+id/sign_in_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
and here is my app gradle file
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "com.ramadanapp.android.firebaseuploadimage"
minSdkVersion 19
targetSdkVersion 26
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
compile 'com.google.firebase:firebase-storage:11.4.0'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.google.firebase:firebase-auth:11.4.0'
compile 'com.google.android.gms:play-services-auth:11.4.0'
}
apply plugin: 'com.google.gms.google-services'

Have you added dependency in build.gradle file at project level? If not then add the below dependency in that.
dependencies{
classpath 'com.google.gms:google-services:3.0.0'
...
}

i think you didn't add the dependencies of play-services-auth
Just add compile 'com.google.android.gms:play-services-auth:11.4.0' dependencies in build.gradle app file like below code
dependencies {
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.google.android.gms:play-services-auth:11.4.0'
}

Transform Exception thrown even when multidexEnabled

I am trying to build a release version of my app in Android Studio, and no matter what I try I get the error message:
Execution failed for task
'app:transformClassesWithJarMergingForRelease'. >
com.android.build.api.transform.TransformException:
java.util.zip.ZipException: duplicate entry:
com/android/volley/Request$Priority.class.
I've enabled multidex, cleaned and rebuilt my app, and nothing is working.
The following is my gradle build:
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "carter.streakly"
minSdkVersion 19
targetSdkVersion 24
versionCode 1
versionName "1.0"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.0.0'
compile 'com.android.support:design:24.0.0'
compile 'com.google.android.gms:play-services-appindexing:8.1.0'
compile 'com.google.android.gms:play-services:9.2.1'
compile 'com.mcxiaoke.volley:library-aar:1.0.0'
compile 'com.android.volley:volley:1.0.0'
compile 'org.jetbrains:annotations-java5:15.0'
compile 'com.android.support:support-v4:24.0.0'
compile 'com.android.support:multidex:1.0.0'
}
In build.gradle dependencies you included two libraries:
compile 'com.mcxiaoke.volley:library-aar:1.0.0'
compile 'com.android.volley:volley:1.0.0'
wherecom.mcxiaoke.volley is basically a fork of official Google library, so you should use only one of them. Please also note, that according to the mcxiaoke/android-volley READ.ME :
(...) this project is deprecated and no longer being maintained, please use official version from jCenter.
compile 'com.android.volley:volley:1.0.0'

The build file may be missing a Gradle plugin.

Error: multiple files define Lorg/json/simple/ItemList

Whenever I try to build an APK for my project, this is the error I get:
Error:Error converting bytecode to dex:
Cause: com.android.dex.DexException: Multiple dex files define Lorg/json/simple/ItemList;
build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "my.package.here"
minSdkVersion 18
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.0'
compile 'org.apache.clerezza.ext:org.json.simple:0.4'
compile 'com.android.support:design:23.2.0'
}
I think that means that more than one dependency defines ItemList. I know one is org.json.simple, what is the other one?
How do I properly exclude ItemList from one of them?
there's nothing in my libs folder so that's not the problem
replace this compile 'org.apache.clerezza.ext:org.json.simple:0.4'
with
compile('com.googlecode.json-simple:json-simple:1.1.1') {
exclude group: 'org.hamcrest', module: 'hamcrest-core'
}
