Answer 1

Error:java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

You should upgrade your gms:play-services & com.android.support version.

 compile 'com.google.android.gms:play-services:11.6.0' //11.8.0
 compile 'com.android.support:support-v4:26.0.2'
 compile 'com.android.support:appcompat-v7:26.0.2'

After that, Clean-Rebuild-Run .

FYI

Enable multiDexEnabled .

 defaultConfig {
        multiDexEnabled true
    }

Answer 2

You have enabled Multidex but missed to add dependency, add the following in dependencies

compile 'com.android.support:multidex:1.0.2'

then make sure your application class extends MultidexApplication. Finally clean and rebuild project. Hope this will fix the issue

For more check multidex doc in developer.android

Answer 3

It is because httpmime include httpclient in its dependencies. You need to exclude it. Currently, you're using the wrong package name for excluding the httpclient:

compile('org.apache.httpcomponents:httpmime:4.3.4') {
    exclude module: 'org.apache.httpcompoents:httpcore'
    exclude module: 'org.apache.httpcompoents:httpclient'
}

it should be:

compile('org.apache.httpcomponents:httpmime:4.3.4') {
   exclude group: 'org.apache.httpcomponents', module: 'httpcore'
   exclude group: 'org.apache.httpcomponents', module: 'httpclient'
}
