Question

我刚开始学习编写代码，并且已经陷入了应该是最简单的部分。我已经安装了所有正确的驱动程序并将手机连接到了我的电脑。 Android studio能够识别我的手机，但在运行应用程序后，我收到以下错误。我也收到了这个基本错误

12:52:55 AM执行任务：[：app：clean，：app：generateDebugSources，：app：generateDebugAndroidTestSources，：app：prepareDebugUnitTestDependencies，：app：mockableAndroidJar，：app：assembleDebug]

12:52:59 AM Gradle build在4s 111ms完成了46次错误

Executing tasks: [:app:clean, :app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:prepareDebugUnitTestDependencies, :app:mockableAndroidJar, :app:assembleDebug]

Configuration on demand is an incubating feature.
Incremental java compilation is an incubating feature.

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

试试这个

dexOptions {
    javaMaxHeapSize "4g"
    preDexLibraries = false
}
