A tool for debugging TransactionTooLargeException on Android.

"Most underrated solution." - Kedar Paranjape, Jun 7 '18 at 14:26

1. Include toolargetool as a dependency (you can remove it again once you've debugged your crash):

   • toolargetool is available from mavenCentral()

   • Add implementation 'com.gu.android:toolargetool:0.3.0' in your module's build.gradle:

     dependencies {
         ...
         implementation 'com.gu.android:toolargetool:0.3.0'
     }
     

2. Import The package

   import com.gu.toolargetool.TooLargeTool;
   

3. Add code to start logging during app start, for example in your Application.onCreate method:

   TooLargeTool.startLogging(this);
   

4. Monitor logcat output to see which components are writing substantial data to the transaction buffer and when:

   $ adb logcat -s TooLargeTool
   

   Example logcat output (TODO: improve this example):

   D/TooLargeTool: MainActivity.onSaveInstanceState wrote: Bundle@200090398 contains 1 keys and measures 0.6 KB when serialized as a Parcel
                                                                           * android:viewHierarchyState = 0.6 KB
   

Note: these instructions will only work if you have the required credentials for publishing to the com.gu Sonatype repository.

1. Increase all the version number in toolargetool/build.gradle
2. Make a commit and tag it with git tag -a v<version number> -m "<message>".
3. Run ./gradlew publishReleasePublicationToSnapshotRepository.
