【问题描述】：
我正在使用 react-native，目前开始使用 redux 并创建了一个应用程序，但是当我在模拟器上运行该应用程序时，它运行良好。然后我通过USB将我的手机与android 6连接起来，它也在工作。但是在 Android 8 的其他设备中它不起作用然后我将 targetSdkVersion 更改为 28 然后它也不起作用我没有得到什么问题。
以下是我的 package.json

maven {
// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
url "$rootDir/../node_modules/react-native/android"
}
maven { url 'https://jitpack.io' }
}
}
task wrapper(type: Wrapper) {
gradleVersion = '4.7'
distributionUrl = distributionUrl.replace("bin", "all")
}
subprojects { subproject ->
afterEvaluate {
if ((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
android {
variantFilter { variant ->
def names = variant.flavors*.name
if (names.contains("reactNative51") || names.contains("reactNative55")) {
setIgnore(true)
}
}
}
}
}
}
我不知道问题出在哪里。提前致谢
【问题讨论】：
-
你能发布崩溃日志吗？所以我们可以看到错误是什么。当设备插入计算机时，您可以使用
adb logcat -d > logs.txt从设备中获取它们。 -
但应用程序甚至没有打开
-
对不起，我没有完整阅读让我检查一下
-
但是如何使用该命令我应该在运行-android之前在终端中触发它
-
您应该能够从 Android Studio 读取日志，从它们而不是从终端构建应用程序
