I clicked on the green triangle, but I just opened the simulator and the installation package was not automatically installed! !
repair:
Supplement:
First of all, I have to execute the following command separately
$ adb push E:\ReactNative\ReactNativeOne1\android\app\build\outputs\apk\app-debug.apk /data/local/tmp/com.reactnativeone
$ adb shell pm install -r "/data/local/tmp/com.reactnativeone"
You need to wait a little longer
Let the bullets fly for a while and be patient.
After the emulator starts, clicking the button should automatically install the application and open it
