I recommend you to debug your application using adb logcat我建议您使用adb logcat调试您的应用程序
Steps to configure配置步骤
Connect your device to your computer将您的设备连接到计算机
Run adb devices
to check out if your device is detected.运行
adb devices
以检查是否检测到您的设备。 If the command doesn't work because "adb is not a command", go to your ANDROID_HOME path, then open platform-tools
如果该命令由于“adb 不是命令”而不起作用,请转到您的ANDROID_HOME路径,然后打开
platform-tools
Now run adb logcat
: This command will output all logs (debug and error levels) coming from your Android Device.现在运行
adb logcat
:此命令将输出来自您的 Android 设备的所有日志(调试和错误级别)。
Install your application again.再次安装您的应用程序。 I recommend you to use
react-native run-android
.我建议您使用
react-native run-android
。 More info: https://reactnative.dev/docs/running-on-device更多信息: https : //reactnative.dev/docs/running-on-device
When your app is going to crash, you will see a Crash Log in the adb logcat output.当您的应用程序崩溃时,您将在adb logcat输出中看到崩溃日志。 Search for your app package name.
搜索您的应用程序包名称。 For your convenience, you could as well have a look here to filter only your app: Filter LogCat to get only the messages from My Application in Android?
为方便起见,您也可以查看此处仅过滤您的应用程序: Filter LogCat to get only the messages from My Application in Android?
Whenever you get a crash log, a stack trace is also provided.每当您获得崩溃日志时,还会提供堆栈跟踪。 That can help you trace the issue.
这可以帮助您跟踪问题。
