Intent.putExtras size limit?

Question

I\'m trying to pass data from one activity to another via Intent.putExtras like this:

private ArrayList         


        

Answer 1

Maximum size is 1MB at Process Level, not at bundle level. This 1MB is for a shared buffer used by all state transactions in progress in the app's process, e.g. onSaveInstanceState, startActivity and others.

On Android 7.0 (API level 24) and higher, the system throws a TransactionTooLargeException when this process level limit is reached. On older versions you only get a warning.

So others suggested, you should research alternatives, if you need to pass a larger payload, e.g. use local database, file system, application level in-memory cache, remote storage, shared preferences (although these need to be small too), etc.
