why gradle always say
"All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 27.1.1, 27.1.0. Examples include
com.android.support:animated-vector-drawable:27.1.1andcom.android.support:exifinterface:27.1.0"
where is 27.1.0 ??
build.gradle :
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
testImplementation 'junit:junit:4.12'
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.google.code.gson:gson:2.6.2'
implementation 'com.google.android.gms:play-services-maps:15.0.1'
implementation 'com.google.android.gms:play-services-location:15.0.1'
implementation 'com.squareup.picasso:picasso:2.71828'
implementation 'com.google.firebase:firebase-core:16.0.3'
implementation 'com.google.firebase:firebase-messaging:17.3.0'
implementation 'com.karumi:dexter:5.0.0'
}
