这让我疯狂了几天。
我无法在Android模拟器上运行我的应用：当我运行react-native run-android时，我会收到以下错误：

我一直在尝试在线发现的任何东西，但是到目前为止，对我没有任何帮助。我该怎么办
我找到了解决方案！
build.gradle中的更改：
classpath 'com.android.tools.build:gradle:3.3.1'
to
classpath 'com.android.tools.build:gradle:3.2.1'
如果您在错误日志中检查，则说React 58使用support-compat：28.0.0，地图模块使用support-compat：26.1.0。我相信Gradle还不够聪明，无法解决。
从您的日志中说：
Dependency path 'theTKMapp:react-native-maps:unspecified' --> 'com.facebook.react:react-native:0.58.4' --> 'com.android.support:appcompat-v7:28.0.0' --> 'com.android.support:support-vector-drawable:28.0.0' --> 'com.android.support:support-compat:28.0.0'
，然后：
Dependency path 'theTKMapp:react-native-maps:unspecified' --> 'com.google.android.gms:play-services-base:16.0.1' --> 'com.google.android.gms:play-services-basement:16.0.1' --> 'com.android.support:support-v4:26.1.0' --> 'com.android.support:support-compat:26.1.0'
React-Native-Maps使用了目前可用的最新版本的Play-Services Base版本，但仍使用support-V4：26.1.0。我们没有使用支持库的版本28的28版的Play-Services Base版本。
您可以尝试从地图模块中的播放服务依赖项中排除支持库。
替换它们。
文件：node_modules/react-native-maps/lib/android/build.gradle ：（您可能必须分配此项目）
implementation ("com.google.android.gms:play-services-base:$googlePlayServicesVersion") { dep ->
dep.exclude group: 'com.android.support', module: 'support-v4'
}
implementation ("com.google.android.gms:play-services-maps:$googlePlayServicesMapsVersion") { dep ->
dep.exclude group: 'com.android.support', module: 'support-v4'
}
或者，您可以将其添加到地图内的Android块中。
android {
configurations.all {
resolutionStrategy.force 'com.android.support:support-compat:28.0.0'
}
}
我的问题是通过引用以下链接来解决的。
也通过将此行添加到React-Native-Maps的build.gradle File
来解决此问题。很重要：我没有立即捕获的是，该行应直接添加到node_modules/react-native-maps/lib/android/build.gradle
中dependencies {
def googlePlayServicesVersion = safeExtGet('googlePlayServicesVersion', DEFAULT_GOOGLE_PLAY_SERVICES_VERSION)
// Variable lookup order : googlePlayServicesMapsVersion > googlePlayServicesVersion > DEFAULT_GOOGLE_PLAY_SERVICES_MAPS_VERSION
def googlePlayServicesMapsVersion = safeExtGet('googlePlayServicesMapsVersion', safeExtGet('googlePlayServicesVersion', DEFAULT_GOOGLE_PLAY_SERVICES_MAPS_VERSION))
def androidMapsUtilsVersion = safeExtGet('androidMapsUtilsVersion', DEFAULT_ANDROID_MAPS_UTILS_VERSION)
compileOnly "com.facebook.react:react-native:+"
implementation "com.google.android.gms:play-services-base:$googlePlayServicesVersion"
implementation "com.google.android.gms:play-services-maps:$googlePlayServicesMapsVersion"
implementation "com.google.maps.android:android-maps-utils:$androidMapsUtilsVersion"
// ⬇️This line made Gradle sync successfully
implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
}
出现会导致压碎的版本混合。您能尝试调整26个版本编译'com.android.support：appcompat-v7:26。 '或编译到最新的
善意做类似无效的事情，然后再重新启动。
将classpath更改为最新classpath并将这一行添加到gradle
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:support-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
这是我的解决方案，将构建制品更改为下面的代码：
buildscript {
ext {
buildToolsVersion = "27.0.3"
minSdkVersion = 16
compileSdkVersion = 27
targetSdkVersion = 26
supportLibVersion = "27.1.1"
}
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.4'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
