android studio 配置相关问题

1：Unknown AVD name, use -list-avds to see valid list.

下午1:26    Emulator: emulator: ERROR: Unknown AVD name [Pixel_2_API_26], use -list-avds to see valid list.

下午1:26    Emulator: Process finished with exit code 1

解决办法：

I experienced the same issue, regardless of the AVD. I'm too new to understand why, but it seems that Android Studio created /.android/avd directories in two locations:

1. /root/.android/avd
2. /home/USERNAME/.android/avd

The .avd and .ini created when creating a new AVD were stored in the 1st location, and the 2nd location was empty. To resolve it, I copied and pasted both the .avd and .ini files for each AVD from 1 to 2 (they needed to be in both in order for AS to see and run the AVD). The emulator then ran successfully.

解决办法：

Disable instant run from settings

Settings > search for instant run > uncheck "Enable Instant Run to hot swap code/resource changes on display"
