解决重复包名导致的安装失败
当遇到因手机上存在重复包名应用而导致的新应用无法安装问题时,可通过CMD命令行使用adb uninstall命令强制卸载冲突应用,再重新安装目标应用即可。

突然爆出这样的问题,无从下手,检测代码也没啥问题,

怀疑是手机上安装有重复包名的应用,但是不记得有这样的应用,

简单粗暴的方式:打开cmd  输入adb uninstall 包名

卸载成功之后,重新安装OK

Initializing Gradle Language Server vscode这个一直在加载是什么意思 还有我运行一个pda项目 PS F:\mom-mls-pda> npx react-native run-android info Running jetifier to migrate libraries to AndroidX. You can disable it using "--no-jetifier" flag. Jetifier found 1363 file(s) to forward-jetify. Using 8 workers... info JS server already running. info Installing the app... The Kotlin Gradle plugin was loaded multiple times in different subprojects, which is not supported and may break the build. This might happen in subprojects that apply the Kotlin plugins with the Gradle 'plugins { ... }' DSL if they specify explicit versions, even if the versions are equal. Please add the Kotlin plugin to the common parent project or the root project, then remove the versions in the subprojects. If the parent project does not need the plugin, add 'apply false' to the plugin line. See: https://docs.gradle.org/current/userguide/plugins.html#sec:subprojects_plugins_dsl The Kotlin plugin was loaded in the following projects: ':react-native-pager-view', ':react-native-screens', ':shopify_flash-list' > Task :app:installDebug Installing APK 'pda_mls_mom_x86_64_2.0.765.apk' on 'Small_Phone(AVD) - 11' for app:debug Installed on 1 device.

PS F:\mom-mls-pda> 总结报错原因 最好深入底层 我这个项目一直卡在这步骤 我已经改了以下文件的build.gradle的 repositories 分别是文件:react-native-pager-view、react-native-screens 、 shopify flash-list 、@react-native-picker 都把对应文件build.gradle的 repositories的改成跟项目的F:\mom-mls-pda\android\build.gradle一样的repositories repositories { // google() // jcenter() maven { url 'https://maven.aliyun.com/repository/google' } maven { url 'https://maven.aliyun.com/repository/jcenter' } maven { url = "https://maven.aliyun.com/repository/gradle-plugin" } maven { url = "https://maven.aliyun.com/repository/public" } } 然后别人也只是和我一样改了上面的一些repositories 为什么他们之后可以直接npx react-native run-android 启动项目而我不行 难道是因为我用了不同版本的yarn.lock 然后别人都能直接运行起来 所以我认为我不能去改android\build.gradle里面的内容 公司统一的
