Error:warning: Ignoring InnerClasses attribute for an anonymous inner class

Question

Kindly help me, I have searched a lot but couldn't find any solution of this error.

build.gragle:

 apply plugin: 'com.android.application'

    android {
        signingConfigs {
            config {

                keyPassword 'leadtrak1'
                storeFile file('/home/sheraz/AndroidStudioProjects/LeadTrak/LeadTrack/docs/LeadTrakKeyStore.jks')
                storePassword 'leadtrak1'
            }
        }

Answer 1

I think this is your main problem

The number of method references in a .dex file cannot exceed 64K.

To solve this put the following lines in your app level gradle file.

Put this line in defaultConfig block

multiDexEnabled true

And add the following dependencies

compile 'com.android.support:multidex:1.0.1'

After this rebuild your project. Hopefully this should resolve your error.

And try avoiding + symbol while adding dependencies in your project as you are doing with play services dependencies

To remove OutOfMemory error add this inside your android block in app level gradle file.

dexOptions {
    //incremental true
    javaMaxHeapSize "4g"
}
