I sometimes get TransactionTooLargeException in onSaveInstanceState. So, I'm assuming that the size of my Bundle being too large is causing this. I'd like to log its exact/approx size so I can get a rough estimate of the amount I need to minimize it by.

Right now, the only way I can find its size is when the TransactionTooLargeException is thrown with

E/JavaBinder: !!! FAILED BINDER TRANSACTION !!!  (parcel size = 1026104)
D/AndroidRuntime: Shutting down VM
I/art: Compiler allocated 6MB to compile void com.example.ExampleModel.writeToParcel(android.os.Parcel, int)
E/UncaughtException: java.lang.RuntimeException: android.os.TransactionTooLargeException: data parcel size 1026104 bytes

  • I think you're attacking the problem from the wrong direction. Why do you have so much data to save? Bundle sizes should rarely go over a few K. Most likely you're storing things that should go in files (like images) or databases (like large parsed network responses). – Gabe Sechan Jan 24 '17 at 18:01
  • I totally agree with you. I was just curious if there was a way to log its size. – Veneet Reddy Jan 24 '17 at 18:10
  • You could write it to a Parcel then marshall the Parcel, which will return a byte[] of the contents. The take the size of that. – Gabe Sechan Jan 24 '17 at 18:41
  • You aren't using a `FragmentStatePagerAdapter` by any chance, are you? https://android.jlelse.eu/rip-transactiontoolargeexception-7256cf14cd69 – Tim Kist Jan 22 '18 at 14:44
  • Maybe too late, but You can try this https://github.com/guardian/toolargetool – Roman Soviak May 08 '18 at 16:44
  • That looks exactly like what I was looking for. You can post it as an answer and I'll accept. – Veneet Reddy May 08 '18 at 18:28

To take advantage of Dex In Process, you’ll need to modify your gradle.properties file and increase the amount of memory allocated to the Gradle Daemon VM by 1 Gb, to a minimum of 2 Gb, using the org.gradle.jvmargs property:

org.gradle.jvmargs=-Xmx2048m
