我使用react-native版本0.59.9创建了一个项目，最低sdk版本为16，目标sdk版本为28。当我生成调试apk时，它在设备上运行良好，但是我使用android studio和jks文件生成了发布apk。它已安装但在vivo y21ll（版本5.1.1）上启动应用时崩溃，但在Redmi note 5（版本6）上已安装并正常工作。 我的 android / app / build.gradle 文件是：

debug/dev mode we prefer to load the
* bundle directly from the development server. Below you can see all

请给我一些提示，指出我哪里出错了，或者我可以采取其他措施以使其在所有设备上正常工作。
答案 0 :(得分：0)
这是因为您已经在应用程序级build.gradle 文件中启用了“ enableProguardInReleaseBuilds” 。通过启用此功能，您将指示gradle运行proguard来缩小发行版本中的Java字节代码，以确保发行APK的尺寸较小。
要解决此问题，我们有两种方法：
首先是在应用程序级build.gradle 文件中禁用enableProguardInReleaseBuilds
def enableProguardInReleaseBuilds = false
您正在使用 react-native-fbsdk ，这会导致发行版本崩溃。在Facebook身份验证过程中，Fbsdk访问用于Facebook身份验证的本机Webview。启用enableProguardInReleaseBuilds后，它也会缩小Fbsdk Java字节码，因此我们也无法访问本地Web视图，从而导致崩溃。因此，如果您不想禁用enableProguardInReleaseBuilds并且您的优先级是较小的APK大小，则无需更改应用程序级build.gradle文件中的任何内容，只需将其保持不变即可：
def enableProguardInReleaseBuilds = true
，然后将以下代码段添加到android应用文件夹中的 proguard-rules.pro 文件中
-keep,allowobfuscation @interface com.facebook.proguard.annotations.DoNotStrip
-keep,allowobfuscation @interface com.facebook.proguard.annotations.KeepGettersAndSetters
-keep,allowobfuscation @interface com.facebook.common.internal.DoNotStrip
# Do not strip any method/class that is annotated with @DoNotStrip
-keep @com.facebook.proguard.annotations.DoNotStrip class *
-keep @com.facebook.common.internal.DoNotStrip class *
-keepclassmembers class * {
@com.facebook.proguard.annotations.DoNotStrip *;
@com.facebook.common.internal.DoNotStrip *;
}
-keepclassmembers @com.facebook.proguard.annotations.KeepGettersAndSetters class * {
void set*(***);
*** get*();
}
-keep class * extends com.facebook.react.bridge.JavaScriptModule { *; }
-keep class * extends com.facebook.react.bridge.NativeModule { *; }
-keepclassmembers,includedescriptorclasses class * { native <methods>; }
-keepclassmembers class * { @com.facebook.react.uimanager.UIProp <fields>; }
-keepclassmembers class * { @com.facebook.react.uimanager.annotations.ReactProp <methods>; }
-keepclassmembers class * { @com.facebook.react.uimanager.annotations.ReactPropGroup <methods>; }
-dontwarn com.facebook.react.**
# okhttp
-keepattributes Signature
-keepattributes *Annotation*
-keep class okhttp3.** { *; }
-keep interface okhttp3.** { *; }
-dontwarn okhttp3.**
# okio
-keep class sun.misc.Unsafe { *; }
-dontwarn java.nio.file.*
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement
-dontwarn okio.**
-keepclassmembers class * {
@android.webkit.JavascriptInterface <methods>;
}
-keepattributes JavascriptInterface
-keepattributes *Annotation*
-dontwarn com.facebook.**
-keep class com.facebook.** {*;}
-optimizations !method/inlining/*
-ignorewarnings
-keep class * {
public private *;
}
尽管您可以为不同的CPU体系结构构建单独的APK，通过在 app级build.gradle中启用 enableSeparateBuildPerCPUArchitecture ，可以将大小进一步减小到当前版本的1/3 strong>文件
def enableSeparateBuildPerCPUArchitecture = true
在集成Facebook身份验证，Razorpay支付网关以及所有所有通过react-native桥访问本机Webview并以上述类似方式解决它们的SDK时，我遇到了类似的问题。
