What if you lose your .keystore file to a React Native app...

I have lost keystore file.
Now getting below error:
Keystore file '/home/jain/Desktop/vaakya_sentence_translation/android/app/debug.keystore' not found for signing config 'debug'.

Losing the debug.keystore file is not a serious issue — it’s auto-generated by Android Studio or the React Native CLI when needed. You can recreate it manually in a few simple steps.

✅ Steps to regenerate debug.keystore

1. Navigate to your Android app folder:

bash
cd /home/jain/Desktop/vaakya_sentence_translation/android/app

2. Run this command to generate a new debug keystore:

bash
keytool -genkeypair -v -keystore debug.keystore -storepass android -keypass android \
  -alias androiddebugkey -keyalg RSA -keysize 2048 -validity 10000

If keytool is not found, it's part of your Java JDK. Try:

bash
which keytool

It’s usually in:

bash
/usr/lib/jvm/java-<version>/bin/keytool

---

📝 Expected output

You’ll be prompted for a few details. You can just press Enter for all of them or enter dummy values.

---

✅ After generation, try again:

bash
npx react-native run-android

Your debug build should now work again.

---

📦 FYI: Where it normally lives

By default, debug.keystore is usually created at:

bash
~/.android/debug.keystore

React Native just copies it to your project path if needed.

Let me know if you'd prefer to point your project back to the system-wide debug keystore instead of creating a new one.
