Bundle Saver

A library that fixes TransactionTooLargeException during state saving and restoring in Runtime.

Just Say No to TransactionTooLargeException

How many times, while sitting in the evening with a cup of tea and browsing through Crashlytics, have you encountered such an Exception?

Fatal Exception: java.lang.RuntimeException
android.os.TransactionTooLargeException: data parcel size 535656 bytes Bundle stats: androidx.lifecycle.BundlableSavedStateRegistry.key [size=534156]

What's happening? How did this occur?

Any developer knows about bundles and their size limitations, but the problem can arise in large applications with deeply nested screens and complex states. When a Binder transaction exceeds 1(or 2) MB, a TransactionTooLargeException will occur. But there is a solution! Introducing, BundleSaver!

Features

• Avoid TransactionTooLargeException: Automatically handles large bundles by saving excess data to disk.
• Easy Integration: Simple initialization and usage with minimal boilerplate code.
• Concurrency Support: Utilizes a cached thread pool for efficient background operations.
• Logging: Built-in logging to monitor bundle sizes and ensure compliance with size limits.
• Memory and Disk Management: Clears data from memory and disk as needed, ensuring optimal performance.

Getting Started

Installation

Add it in your root build.gradle at the end of repositories:

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Add the BundleSaver dependency to your build.gradle file in App module:

dependencies {
    implementation "com.github.kernel0x:bundlesaver:1.0.0"
}

Usage

Initialize an instance of BundleManager (preferably in the Application's onCreate() method)

class App : Application() {

    override fun onCreate() {
        super.onCreate()
        BundleManager.initialize(this)
    }
}

Next, you should add the following to each of your Activities (Important! The order must be exactly like this!).

class MainActivity : Activity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        BundleManager.restoreInstanceState(this, savedInstanceState)
        super.onCreate(savedInstanceState)
    }

    override fun onSaveInstanceState(outState: Bundle) {
        super.onSaveInstanceState(outState)
        BundleManager.saveInstanceState(this, outState)
    }
}

That's it!

Optional

Clearing Data and Logging.
