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

Answer 1

I got an error similar to this when checking out a project from SVN

what caused it was when SVN finished the check out Android Studio asked if i wanted to create it as a project - and I clicked yes , turns out it already was a project and trying to make it a project within a project broke Gradle's ability to build it - but checking the project out and just opening the folder worked for me

Answer 2

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"
}

Answer 3

Can you replace and check

    defaultConfig {
        applicationId "leadtrak.activities"
        minSdkVersion 9
        targetSdkVersion 9
        multiDexEnabled true
    }
        dexOptions {
     javaMaxHeapSize "4g"

     }

     signingConfigs {
        release {
            keyAlias 'leadtrak'
            keyPassword 'leadtrak1'
            storeFile file('/home/sheraz/AndroidStudioProjects/LeadTrak/LeadTrack/docs/LeadTrakKeyStore.jks')
            storePassword 'leadtrak1'
        }
    }

     buildTypes {
        release {
            signingConfig signingConfigs.release
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-   android.txt'), 'proguard-rules.txt'


        }
    }

   dependencies {
    compile 'com.android.support:multidex:1.0.0'
    compile 'com.android.support:support-v4:24.2.1'
    compile 'com.google.android.gms:play-services:+'
    compile files('libs/acra-4.4.0.jar')
