com.android.ddmlib.InstallException: Failed to establish session react-native

Question

I am trying to run react-native android app in my nexus5 emulator

adb devices
List of devices attached
emulator-5554   device

started pack

Answer 1

Try : react-native run-android --deviceId YOUR_ID.

Answer 2

adb is known to be flaky. Try:

• Restarting adb with $ adb kill-server
• Restarting the emulator
• Using Genymotion instead of stock Google emulator.

Answer 3

Probable Cause

I faced this issue recently , I had first developed an app called 'myApp' in CordovaJS where the app domain was com.myapp and had it installed (this was months before I got into react ). Then when I switched to react-native I did an app with a domain com.myapp and ran into the same problem you are in.

So I figured out that there was conflicts when it came to domain and source .

Solution :

Uninstall the app that has a similar domain as the one that you are installing eg com.example , then reboot your phone .

It worked for me , I hope it works for you too.

Answer 4

If your device or emulator have an application having same name with the application you are building. Just remove the old one. It will resolve the issue.

Answer 5

For your AVD emulator settings, try to make sure the "Use Host GPU" setting is checked, and relaunch the emulator and try again.

Answer 6

For those like me having this issue in the emulator, one more tip: try to free up the available storage space in the emulator. That worked for me.

So many test apps and previous developed apps installed XD
