Change meta-data value android Programmatically

Question

how to change meta-data value Programmatically in manifest or string resource in string value

Answer 1

Using Inject build variables into the manifest you can change metadata value programmatically

In build.gradle

defaultConfig {
        manifestPlaceholders = [ senderid:"12345"]
    }

buildTypes {
        release {
            manifestPlaceholders = [ senderid:"56789"]
        }
    }

In Manifest file

<meta-data
            android:name="SENDER_ID"
              android:value="${senderid}" />
