N.B. This Question Is not a match as I cant find any working solution.
I have used almost every process to solve this but still facing same.
First: multiDexEnabled true
Second: compile 'com.android.support:multidex:1.0.1'
Third: org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m (in Local.properties)
Fourth: android:name="android.support.multidex.MultiDexApplication" (In manifest.xml)
Fifth: Clean & Rebuild
Sixth: File < Invalidate cache & Restart
If anyone is looking for solution, These may work for you. But for me none are working.
What should I do ? (I'm working on Digital wallet project).
