Android – Could not get unknown property ‘RELEASE_STORE_PASSWORD’ for SigningConfig_Decorated{name=debugY

Easiest ways ever:

Update added for Android Studio V 2.2 in last step

There are two ways to do this.

1. Faster way:

1. Open Android Studio
2. Open your Project
3. Click on Gradle (From Right Side Panel, you will see Gradle Bar)
4. Click on Refresh (Click on Refresh from Gradle Bar, you will see List Gradle scripts of your Project)
5. Click on Your Project (Your Project Name form List (root))
6. Click on Tasks
7. Click on Android
8. Double Click on signingReport (You will get SHA1 and MD5 in Run Bar(Sometimes it will be in Gradle Console))
9. Select app module from module selection dropdown to run or debug your application

Check the screenshot below:

2. Work with Google Maps Activity:

1. Open Android Studio
2. Open Your Project
3. Click on File menu -> Select New -> Click on Google -> Select Google Maps Activity
4. A dialog would appear -> Click on Finish
5. Android Studio would automatically generate an XML file named with google_maps_api.xml
6. You would get debug SHA1 key here (at line number 10 of the XML file)

Android Studio V 2.2 Update

Done.

try this

 def key="default"
def storePass="default"
def keyPass="default"

if (project.hasProperty("KEY_ALIAS")) {
    key = KEY_ALIAS
}
if (project.hasProperty("STORE_PASSWORD")) {
    storePass = STORE_PASSWORD
}
if (project.hasProperty("KEY_PASSWORD")) {
    keyPass = KEY_PASSWORD
}


signingConfigs {
    release {
        storeFile file("C:/Android/Dev/keystore/dm.keystore")
        keyAlias key
        storePassword storePass
        keyPassword keyPass
    }
}

i also recommend you to store your signing information in separate file
