What happened when the uniapp project was packaged and installed and the phone got stuck?

Recently, I was developing a mobile application based on uniapp, but I encountered a troubling problem when packaging the project and installing it on the mobile phone: the application would get stuck on the welcome interface after startup and could not run normally.

So I started trying and exploring, and finally found a solution and shared it with everyone.

First of all, I attribute the cause of the problem to multiple aspects:

1. Code problem: It may be because there is a problem with the code written, such as an infinite loop, memory leak, etc.
2. The resource image is too large: If the application uses many large images, it will cause the application to occupy too many resources, causing it to freeze.
3. Model adaptation problem: Sometimes uniapp’s adaptation to different models is not perfect enough, which may also cause the application to freeze.

Solution:

1. Code problem:

First we need to use Chrome to open the developer tools and see if the application starts. There will be an error message. If so, you need to carefully check the code to find the problem and fix it.

If no error is reported, you need to use debugging tools to debug when the application is stuck. You can use Vue Devtools for debugging to find possible problems. If code problems are found, fix them promptly.

2. Image resource optimization:

If your application uses many large images, you can consider using image compression tools to optimize and reduce the size of image files. You can use TinyPNG, webp and other image optimization tools for compression.

In addition, you can also optimize image loading by setting lazy loading and other methods, thereby reducing the application's dependence on resources and avoiding stuck problems.

3. Model adaptation:

If the application is stuck on certain models, it can be solved by adapting to different models.

Uniapp provides adaptation solutions for different models, which can be configured in the manifest.json file. At the same time, you can also use adaptation tools such as flexible.js to adapt the application. By adapting to different models, stuck problems can be avoided and application stability improved.

Summary:

Through the above steps, I finally solved the problem of the uniapp project being packaged and installed until the phone got stuck. Before formal deployment, be sure to carefully check the code, optimize resources, and adapt to different models. Only in this way can we ensure the integrity and stability of the application.
