Answer 1

the adb version on your system is different from the adb version on the android sdk platform-tools . Below suggestion is work for me for Linux operating system

1. check sys adb version run the below command

adb version

Android Debug Bridge version 1.0.39

2. check sdk adb version

cd /root/Android/Sdk/platform-tools

./adb version

Android Debug Bridge version 1.0.32

3. copy

rm /usr/bin/adb

[Note : the above command remove the existing adb then copy the adb from sdk/platform-tools directory ]

sudo cp /root/Android/Sdk/platform-tools/adb /usr/bin/adb

Then run the project using this command

react-native run-android
