Recently, I upgraded Android Studio from version 1.5 to 2.0 but since then I observe that the number of errors and warnings has increased. Most of the errors do not make sense. Can someone please help:

You can get rid of the meaningless warnings and errors by deleting the .idea folder that Android Studio 1.5 created and importing the the project into Android Studio 2.0 as a gradle project. It will recreate the .idea folder automatically.

Adding -keepattributes EnclosingMethod to proguard rules suppresses these errors and warnings.

Worked for me like a charm.

Update : Adding -keepattributes EnclosingMethod to proguard rules actually changes how the classes are obfuscated. This preserves the optional attributes that are typically necessary for your code to be executed WITHOUT such issue.

I had pretty much the same messages after integrating SimpleXML retrofit2 converter in my project. I had to exclude some libraries that were already bundled with Android to make it build properly.

Like so:

compile ("com.squareup.retrofit2:converter-simplexml:2.0.2") {
exclude group: 'xpp3', module: 'xpp3'
exclude group: 'stax', module: 'stax-api'
exclude group: 'stax', module: 'stax'}

After last update to Android Studio 2.2 beta, I solved problem by updating "buildToolsVersion" to last possible version (from 24 to 24.0.1) in app build.gradle.

Have you tried to clear the project and rebuild ? In the build.gradle file what version on gradle do you have ?

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

building the Common Collections would produce the required JARs ...

my build.gradle looks about like this, with commons-collections excluded & substituted with a more recent version (one still needs to build from source, just as the message tells one to do):

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    // compile 'commons-collections:commons-collections:3.2.2'
    // compile 'org.apache.commons:commons-collections4:4.1'
    compile ('org.apache.velocity:velocity:1.7') {
        exclude group: 'commons-collections', module: 'commons-collections'
    }
}

The answer should be here NewRelic causing build errors

add in proguard-rules.pro

-keep class         org.apache.commons.beanutils.** { *; }
-keep interface     org.apache.commons.beanutils.** { *; }
-keep enum          org.apache.commons.beanutils.** { *; }
...
