Setting up a real-world development environment requires the following steps:1. Declare the application to be debug in the application's manifest file;2. Open the application debugging support;For apps created through Eclipse, you can omit step 2, because debugging support for your app automatically opens when the Eclipse IDE launches the app.Note: In the application development process, to manually enable debugging support in the manifest file, it is best to turn off debugging support before th
