构建 apk 和 appbundle 项目时出现问题

Question

我尝试使用

flutter_tflite: ^1.0.1

包来构建实时对象检测应用程序。当我在模拟器上测试时一切正常。但是，当我尝试将其构建到 APK 和应用程序包中时，发生了以下错误：

---

Execution failed for task ':flutter_tflite:verifyReleaseResources'.
> A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action

            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig = signingConfigs.release
        }
    }
}

flutter {
    source = "../.."
}

有人请帮帮我！这项作业的截止日期是下周🥹

在 android/app/build.gradle 中，在 android 块中添加以下设置。

aaptOptions {
    noCompress 'tflite'
    noCompress 'lite'
}

所以你必须将你的 app/build.gradle 配置为：

plugins {
    id "com.android.application"
    id "kotlin-android"
    // The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugins.
    id "dev.flutter.flutter-gradle-plugin"
}

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

android {
    namespace = "com.example.myappku"
    compileSdk = flutter.compileSdkVersion
    ndkVersion = "27.0.12077973"

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_1_8
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId = "com.example.myappku"
        // You can update the following values to match your application needs.
        // For more information, see: https://flutter.dev/to/review-gradle-config.
        minSdk = flutter.minSdkVersion
        targetSdk = flutter.targetSdkVersion
        versionCode = flutter.versionCode
        versionName = flutter.versionName
    }

    signingConfigs {
        release {
            keyAlias = keystoreProperties['keyAlias']
            keyPassword = keystoreProperties['keyPassword']
            storeFile = keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword = keystoreProperties['storePassword']
        }
    }

    buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile(
                    'proguard-android-optimize.txt'),
                    'proguard-rules.pro'
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig = signingConfigs.release
        }
    }

    aaptOptions {
        noCompress 'tflite'
        noCompress 'lite'
    }
}

flutter {
    source = "../.."
}

然后重建您的项目。

希望对你有帮助！
