I have completed new setup in windows for react native : whenever I am trying to start the emulator from command I am getting this issue , but I can open emulator inside android studio without any problem
> react-native run-android
* daemon not running; starting now at tcp:5037
* daemon started successfully
info Launching emulator...
error Failed to launch emulator. Reason: The emulator (INFO | Storing crashdata in: C:\Users\arunk\AppData\Local\Temp\\AndroidEmulator\emu-crash-34.1.18.db, detection is enabled for process: 13500) quit before it finished opening. You can try starting the emulator manually from the terminal with: C:\Users\arunk\AppData\Local\Android\Sdk/emulator/emulator @INFO | Storing crashdata in: C:\Users\arunk\AppData\Local\Temp\\AndroidEmulator\emu-crash-34.1.18.db, detection is enabled for process: 13500.

raised issue on github too text
I am trying to run android emulator usign
npm run android
or
npx react-native run-android
expected : after metro start android emulator should start automatically but it is failing everytime and giving this emu-crash.db logs issue
trying to delete that log file too tried to run different version of react native too
I have the same problem.
This bug came from the command line emulator -list-avds
Now this command line add a new log at the first line :
INFO | Storing crashdata in: /tmp/android-xxx/emu-crash-34.1.18.db, detection is enabled for process: 20206
.Pixel_2_API_31
2.7_QVGA_API_31
3.2_QVGA_ADP2_API_31
3.7_WVGA_Nexus_One_API_31
6.7_Horizontal_Fold-in_API_31
Pixel_2_API_29
Pixel_2_API_33
Pixel_XL_API_31
The problem is that react-native take always the first emulator in this list as default emulator to launch. But now it try to open INFO | Storing crashdata in: /tmp/android-matthias/emu-crash-34.1.18.db, detection is enabled for process: 20206 that is not a emulator name, but just a log info.
To launch the emulator, until a fix, you can still use the command line
emulator @name_of_device
then use the common command :
npm run android
