颤振问题：本机崩溃

Question

在 Google Play 上部署我的 Flutter 应用后，它在启动时崩溃。它适用于 2 台设备（Google 测试设备 on Play），而其他设备则出现以下错误。

问题：java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/abc.pota.tallxy-1/base.apk"],nativeLibraryDirectories=[/data/app/ abc.pota.tallxy-1/lib/arm64, /data/app/abc.pota.tallxy-1/base.apk!/lib/arm64-v8a, /system/lib64, /vendor/lib64, /system/vendor /lib64, /product/lib64]]] 找不到“libflutter.so”

所以我将以下代码放在我的 app/build.gradle 文件中。

defaultConfig {
    ..
    ndk.abiFilters 'armeabi-v7a','arm64-v8a','x86','x86_64'
}

但并非在所有 Google 测试设备甚至我的手机上（当我从 Google Play 下载时）它都会崩溃并出现以下错误。

问题：abc.pota.tallxy 的原生崩溃

感谢您的宝贵时间

Answer 1

如果您使用minifyEnabled true，您将不得不面对这个问题。

---

解决方案 1

在您的 build.gradle 文件中删除此行。

---

解决方案 2

如果您仍想使用minifyEnabled，您还必须按照以下步骤操作。

我。将extra-gen-snapshot-options=--obfuscate 添加到您的android/gradle.properties

二。创建/android/app/proguard-rules.pro 文件并添加下列规则。

#Flutter Wrapper
-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.**  { *; }
-keep class io.flutter.util.**  { *; }
-keep class io.flutter.view.**  { *; }
-keep class io.flutter.**  { *; }
-keep class io.flutter.plugins.**  { *; }

三。在您的build.gradle(app) 中，添加此

buildTypes {

    release {

        signingConfig signingConfigs.debug

        minifyEnabled true
        useProguard true

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

    }
}
