To run dex in process, the Gradle daemon needs a larger heap. It currently has 1024 MB. For faster builds, increase the maximum heap size for the Gradle daemon to at least 1536 MB. To do this set org.gradle.jvmargs=-Xmx1536M in the project gradle.properties. For more information see https://docs.gradle.org/current/userguide/build_environment.html

andorid studio 运行正常，通过命令行react-native run-android 报错。
如图：

解决：
1：app下build.gradle修改

  defaultConfig {
        minSdkVersion 19
        targetSdkVersion 26
        versionCode 1
        versionName "1.0.1"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
        multiDexEnabled true
    }
    dexOptions {
        javaMaxHeapSize "2g"
        preDexLibraries = false;
    }

2:项目目录下gradle.properties添加

org.gradle.daemon=true
org.gradle.jvmargs=-Xmx2560m

至于2560这个数字根据它提示的修改。
然后编译同步gradle
react-native run-android.
成功。
