toolargetool

A tool for debugging TransactionTooLargeException on Android.

Usage

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

   implementation "com.ymnd.android:toolargetool:1.0.0"
   
   implementation project(':toolargetool')
   testImplementation project(':toolargetool_op')
   

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

   new TooLargeTool().startLogging(this); // Java
   TooLargeTool().startLogging(this); //Kotlin
   

3. Set LoggerParam if use custom logger:

   // Java
   new LoggerParam.Builder()
           .activityCallback(/* callback bundle */)
           .fragmentCallback(/* callback bundle */)
           .build();
   
   // prepare Utils to easily handle log
   UtilsKt.format()
   UtilsKt.bundleBreakdown()
   

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
