[英]npx react-native run-android doesn't start emulator and doesn't run if emulator is running
[英]Running react-native project on Android emulator doesn't work
由于我想在我的应用程序上使用蓝牙,我下载并链接react-native-ble-plx。 当我尝试react-native run-Android时出现以下错误:
Task :app:processDebugManifest FAILED
C:\Users\Aurelien\Desktop\Leroy-Somer\AMJE nativ\AMJE\android\app\src\debug\AndroidManifest.xml Error:
uses-sdk:minSdkVersion 16 cannot be smaller than version 18 declared in library [:react-native-ble-plx] C:\Users\Aurelien\Desktop\Leroy-Somer\AMJE nativ\AMJE\node_modules\react-native-ble-plx\android\build\intermediates\library_manifest\debug\AndroidManifest.xml as the library might be using APIs not available in 16
Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 18,
or use tools:overrideLibrary="com.polidea.reactnativeble" to force usage (may lead to runtime failures)
我知道我有错误的SDK版本,但我不知道如何更新它
如何更新?
更新后我是否必须创建一个新的React Native项目?
正如你在这里看到的那样https://github.com/Polidea/react-native-ble-plx/blob/master/android/build.gradle“react-native-ble-plx ”的min-sdk为18,但你的project的min-sdk为16.所以你没有资格使用该库。 到目前为止,您可以做的最简单的事情是转到“project / android / app / build.gradle”文件并将自己的min-sdk增加到18
将app / build.gradle中的最小sdk版本更新为。
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.myapplication"
minSdkVersion 18
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
}
