When setting up an environment for Android, I was not happy! [Continuous increase]

========================================================== ====================

1. When the system is reinstalled and the previous eclipse and code are used, an error indicating that the device cannot be connected is reported!

Solution:

1. Open the AVD Manager dialog box on the toolbar and create a virtual device.

2. Project-> properties-> Run/debug settings:
(1). Select "Launching new_configuration"
(2). Delete
(3). OK
The reason is that your project code is not associated with a virtual device. Of course, it cannot be started.

 

Note: If you have multiple project codes, I tried to turn off the current virtual device and then repeat Step 2, that is, the device only runs one project at a time.

The restart speed is quite slow, so be patient.
