To run dex in process, the Gradle daemon needs a larger heap. It currently has 910 MB

Question

Actually the main error is \"java.exe finished with non-zero exit value 1\". First i tell you every problem which i faced after installing studio:

Answer 1

Issue

In gradle plugin version 2.0.0-alpha7 and -alpha8 Dex runs inside gradle build process as opposed to a separate process.

Option a)

Change gradle plugin version to 2.0.0-alpha9 where in-process Dex is disabled by default.

classpath 'com.android.tools.build:gradle:2.0.0-alpha9'

Option b)

Disable in-process dex in your app module build.gradle:

android {
    // ...
    dexOptions {
        dexInProcess = false
    }
}

Option c)

Increase memory available to gradle process.

Create or update gradle.properties file in your project root directory:

# Default value: -Xmx10248m -XX:MaxPermSize=256m
org.gradle.jvmargs=-Xmx4g -XX:MaxPermSize=512m

And update your app module build.gradle file:

dexOptions {
    preDexLibraries true
    javaMaxHeapSize "3g"
    incremental true
    dexInProcess = true
}

These values are experimental and work for my setup. I use 3 GB for dex and 4 GB for gradle (3 + 1 GB).

Note

If you have any issues update to alpha9 anyway.
