Question

我正在尝试生成我的第一个反应原生应用程序的签名apk我按照official site of react native

中的步骤

我尝试了这个命令cd android && gradlew assembleRelease，并成功生成了apk。

但是当我尝试使用cd android && gradlew installRelease在我的真实设备上测试此apk时，应用程序崩溃了，尽管它在genymotion模拟器上按预期工作。

我错过了什么吗？

感谢任何帮助。提前致谢

更新我无法在我的设备上进行调试，因为我总是看到红色屏幕显示Unable to download JS bundle，尽管我已经完成了官方网站上提到的关于running on the device的所有内容

感谢@G。 Hamaide为他的answer，它对我有用，但在buildTypes app/build.gradle中添加了一个，正如官方文档中提到的那样添加此行signingConfig signingConfigs.release。

buildTypes {
        release {
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
            signingConfig signingConfigs.release
        }
    }

那加上什么是@G。哈马德在上面提到的答案中提到过。

改变这个：
def enableProguardInReleaseBuilds = true 
到此：
def enableProguardInReleaseBuilds = false 
然后再次运行步骤为您创建APK。
