  I don’t know why the files can’t be transferred to the phone. Even after downloading the file assistant, I can’t connect to the phone. So use the simplest method.
  This error is because Hbuilder cannot send and install the apk to the mobile phone. Open the directory it says C:\Users\[自己的目录]\Downloads\HBuilderX.3.7.11.20230427\HBuilderX\plugins\launcher\base\android_base.apk, directly send the apk to the mobile phone via WeChat, then manually change the name, click Install, and this icon will appear after installation.
  
  After installation, return to the computer Hbuilder and run it again.
  Error occurred:
  Failed to connect to localhost/127.0.0.1:8080
  Turn off HBuilder on mobile phone, recompile on computer, just try twice more.

Run into emulator

• Download and install Android Studio. The official uni-app provides a download address and installation tutorial. I will talk about something the official does not explain in detail here. After downloading, just click down by default during installation. After installing studio.
  遇到的问题
  1. Click on SDK Manager and find that there is no SDK Platform. Follow this tutorial , it's really detailed.
  
  2. Modify the SDK directory, and then the installation fails. It does not report an error, it means that the package already exists, so the existing package is used. After seeing this comment, I modified the path and moved it one level up.
  
  3. Failed to download the package: Because I have "technology" support, the agent here chooses Auto-detect. You can try it Check connection. From the details downloaded later, you can see that https://dl.google.comthe installation package is downloaded from, so just use this URL to test. If this test is successful, it means that there is no problem with the subsequent installation network.
  
  The following log must appear to indicate that it has been installed 成功, otherwise you will not be able to select the sdk platform and sdk tools when you click finish.
  
  Just follow the detailed tutorial above and continue. God knows how long I tried before I finally succeeded. A handful of bitter tears.
• Android native project configuration. You can refer to the uni-app tutorial , which is recommended as 方式二：导入工程the bread is already placed. I will mainly explain some details not mentioned here and the problems I encountered.

  2. Androidmanifest.xmlUnder manifeststhe directory, labels have been placed meta-data. Just change the value.
