获取错误：java.lang.OutOfMemoryError：超出了GC开销限制

Question

I am getting Error:UNEXPECTED TOP-LEVEL. The log shows to increase the heap size. I have added android:largeHeap = true in an application. Then also I am getting this error.

Manifest:

  <application
    android:allowBackup="true"
    android:name="android.support.multidex.MultiDexApplication"
    android:icon="@drawable/icon1"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

Log:

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html

What to do?

Answer 1

In your build.gradle Try to add this :

dexOptions {
    incremental true
    javaMaxHeapSize "4g"
}

• incremental true is using to speed up your builds.
• javaMaxHeapSize "4g" to specify the heap size for the dex process.

Answer 2

The log says

"To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties."

So open your gradle.properties file and add the line "org.gradle.jvmargs=-Xmx2048M"

Answer 3

Your log:

To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties
