React Native Generating Signed APK "KeyStore file not set for signing config release"

I am trying to generate a signed APK. I have my password.keystore file located in \Dictionary\android\app and when i ran gradlew assembleRelease on cmd, the error:

Execution failed for task ':app:validateSigningRelease'.

Keystore file not set for signing config release

Where should I store my password.keystore file? Because when I commented off the if (project.hasProperty("password.keystore") { it seems to work but with the following error instead:

Unable to process incoming event 'ProgressComplete ' (ProgressCompleteEvent)

How should I write my if condition or where should I store the password.keystore file?

The source code is as follows:

signingConfigs {
  release {
    if (project.hasProperty("password.keystore")) {
      storeFile file("password.keystore")
      storePassword "password"
      keyAlias "username"
      keyPassword "password"


The keystore file has to be in the android/app folder.

The message 'Keystore file not set for signing config release' has to do that there is no signingConfig in the android/app/build.gradle file.

buildTypes {
    release {
        // other settings
        signingConfig signingConfigs.release

For testing you can just hard coded the settings in the android/app/build.gradle, instead off set it in the This was fixing for me the problem with 'Keystore was tampered with, or password was incorrect'

  signingConfigs {
    release {
        //if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
            storeFile file("key.keystore")
            storePassword "****"
            keyAlias "myKey"
            keyPassword "****"
       // }

I have found a solution!

If you have followed React Native's official instructions, just like me, you add following to your


And then comes the part that I totally misunderstood.

In the app/build.gradle-file, you are not supposed to replace the strings. If your is like the one I pasted over, your app/build.gradle should look like this:

signingConfigs {
    release {
        if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
            storeFile file(MYAPP_RELEASE_STORE_FILE)
            storePassword MYAPP_RELEASE_STORE_PASSWORD
            keyAlias MYAPP_RELEASE_KEY_ALIAS
            keyPassword MYAPP_RELEASE_KEY_PASSWORD

What I originally did was replacing the strings (i.e. 'MYAPP_RELEASE_STORE_FILE' with the path to my keystore-file), but you are not supposed to replace any of the variables at all. I guess you could see the connection between the strings we created in and the release-config we have made in app/build.gradle.

Remember to have your .keystore-file inside android/app as well.

In my case, my project was on RN version 0.59 while I was using 0.60 RC documentation. So inside app/build.gradle

If version 0.59 :

if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {

If version 0.60 :

if (project.hasProperty('MYAPP_UPLOAD_STORE_FILE')) {

The difference is the change from RELEASE to UPLOAD

I had exact same issue. Turn out I forgot to edit file. It should look like this:



project.hasProperty will be looking in your file for a variable named password.keystore.

Go into ~/.gradle and see if you have a file, if you do, make sure the variable password.keystore is there, it should point to your keystore file: password.keystore=password.keystore.

Although you should name it something different, like MYAPP_RELEASE_STORE_FILE=password.keystore. Then when you run ./gradlew assembleRelease your project will have the property it's looking for and the following will resolve true and allow gradlew to set all the signingConfigs.release properties:

if (project.hasProperty(MYAPP_RELEASE_STORE_FILE)) {
    storeFile file(...)
    storePassword your_password_property

After exploring all answers regarding this issue, none of the answer helped!

So tried below experiment and it helped!!!!

Place the my-release-key.keystore file under the android directory in your project folder.

I actually prefer to store these parameters outside the app repo using environment variables since it contains sensitive information like password, etc.

signingConfigs {
    release {
        if (System.env.MYAPP_RELEASE_STORE_FILE != null) {
            storeFile       file(System.env.MYAPP_RELEASE_STORE_FILE)
            storePassword   System.env.MYAPP_RELEASE_STORE_PASSWORD
            keyAlias        System.env.MYAPP_RELEASE_KEY_ALIAS
            keyPassword     System.env.MYAPP_RELEASE_KEY_PASSWORD

Once this is done, I can just load up a bash script which has the details like

# path to my keystore
export MYAPP_RELEASE_STORE_FILE=/path/to/key.file
# ...

This way the signing config is completely isolated from the repo. This prevents you from making accidental commits with your secrets.

Make sure you have placed your .keystore file inside app folder and do gradle changes like below:

    signingConfigs {
    release {
        storeFile file(RELEASE_STORE_FILE)
        storePassword RELEASE_STORE_PASSWORD
        keyAlias RELEASE_KEY_ALIAS
        keyPassword RELEASE_KEY_PASSWORD

Make sure alias name used in is same as the one used while creating keystore ( using keytool )
