The number of method references in a .dex file cannot exceed 64k

Gradle build fails with error "The number of method references in a .dex file cannot exceed 64k "

As the error suggests you cannot have more than 64k methods in one classes.dex file. One way around this is to use enable MultiDex in your build.gradle

multiDexEnabled true

Android Studio - bindView called multiple times for each listView row


bindView inside a custom CursorAdapter is called 6-7 times for each row.


There is no direct way to control when bindView is called. Android operating system does it as and when required it in order to properly measure and draw the layout. In this particular case the issue was caused by setting layout width to wrap_content in the ListView layout. Changing this to match_parent fully resolved the issue and bindView is now called only once for each ListView row.
