React本机构建签名APK失败

我创建了一个带有react-native的新项目，包含很少的包（react-native-camera，react-native-device-info，react-native-elements，react-native-geocoder，react-native-qrcode-scanner，react-本机矢量图标，反应导航）但我无法弄清楚它为什么不构建 . 我执行此命令来生成APK：

gradlew clean
gradlew assembleRelease

输出是：

• 出了什么问题：任务':react-native-device-info:verifyReleaseResources'的执行失败 .

com.android.ide.common.process.ProcessException：无法执行aapt

如果我删除react-native-device-info软件包，则会出现下一个安装的包为react-native-camera的错误 .

如果我在grade.properties中设置android.enableAapt2 = true（在aapt2禁用的情况下引发错误），我收到此错误：

D:\WorkingCopy\Apps\CpVehicle\src\android\app\build\intermediates\res\merged\release\drawable-hdpi\node_modules_reactnavigation_src_views_assets_backicon.png: error: uncompiled PNG file passed as argument. Must be compiled first into .flat file..
error: failed parsing overlays.

我的build.gradle文件是这样的：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "$rootDir/../node_modules/react-native/android" }
        maven { url "https://jitpack.io" }
        maven { url 'https://maven.google.com' }
        mavenCentral()
        google()
    }
}


subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion '27.1.1'
            }
        }
    }
}

gradle-wrapper.properties：

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

当项目处于开始阶段时，我构建了APK而没有错误 .

如果我尝试使用Android Studio构建它，它可以正常工作，但是在它出现之前崩溃的设备上打开应用程序 . 在Play商店控制台中，我收到此错误：

FATAL EXCEPTION: Thread-3
Process: com.cpvehicle, PID: 8053

谢谢 .
