android.os.TransactionTooLargeException解决方案，Kotlin

 

首先，特意制造一个让Android发生TransactionTooLargeException的场景，一个Activity启动另外一个Activity，在Intent的Bundle里面塞入一个大的ArrayList:

import android.content.Intent
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import kotlinx.coroutines.CoroutineScope
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.launch
import java.nio.charset.Charset


class MainActivity : AppCompatActivity() {
    companion object {
        const val MY_KEY = "my_key"
        const val MY_BUNDLE = "my_bundle"
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        val ctx = this
        CoroutineScope(Dispatchers.IO).launch {
            val bytes = "z".toByteArray(Charset.defaultCharset())
            val count = 1024 * 1024
            val list = arrayListOf<ByteArray>()
            for (i in 0..count) {
                list.add(bytes)
            }

            val bundle = Bundle()
            bundle.putSerializable(MY_KEY, list)

            CoroutineScope(Dispatchers.Main).launch {
                val intent = Intent(ctx, MyTestActivity::class.java)
                intent.putExtra(MY_BUNDLE, bundle)
                startActivity(intent)
            }
        }
    }
}

 

被启动的MyTestActivity:

import android.os.Bundle
import android.util.Log
import androidx.appcompat.app.AppCompatActivity

class MyTestActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val bundle = intent.getBundleExtra(MainActivity.MY_BUNDLE)
        Log.d("fly", "MyTestActivity onCreate size=${bundle?.getSerializable(MainActivity.MY_KEY, ArrayList::class.java)?.size}")
    }
}

 

 

MainActivity运行起来后，应用直接崩溃抛错：

 

!!! FAILED BINDER TRANSACTION !!!  (parcel size = 12583376） 

Caused by: android.os.TransactionTooLargeException: data parcel size 12583376 bytes

因为Bundle传输的数据总量大小不能超过1MB，且应用内的Activity/Frgment共享这1MB。

 

解决方案

两边改造，换用Binder，参考（ Android Bundle putBinder传输超过1MB数据，Kotlin-CSDN博客 ）：

 

import android.content.Intent
import android.os.Binder
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import kotlinx.coroutines.CoroutineScope
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.launch
import java.nio.charset.Charset

class MainActivity : AppCompatActivity() {
    companion object {
        const val MY_KEY = "my_key"
        const val MY_BUNDLE = "my_bundle"
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        val ctx = this
        CoroutineScope(Dispatchers.IO).launch {
            val bytes = "z".toByteArray(Charset.defaultCharset())
            val count = 1024 * 1024
            val list = arrayListOf<ByteArray>()
            for (i in 0..count) {
                list.add(bytes)
            }

            val bundle = Bundle()
            bundle.putBinder(MY_KEY, MyBinder(list))

            CoroutineScope(Dispatchers.Main).launch {
                val intent = Intent(ctx, MyTestActivity::class.java)
                intent.putExtra(MY_BUNDLE, bundle)
                startActivity(intent)
            }
        }
    }
}

class MyBinder : Binder {
    private var data: ArrayList<ByteArray>? = null

    constructor(data: ArrayList<ByteArray>?) {
        this.data = data
    }

    fun getData(): ArrayList<ByteArray>? {
        return data
    }
}

 

 

import android.os.Bundle
import android.util.Log
import androidx.appcompat.app.AppCompatActivity

class MyTestActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val bundle = intent.getBundleExtra(MainActivity.MY_BUNDLE)
        val binder = bundle?.getBinder(MainActivity.MY_KEY) as MyBinder
        Log.d("fly", "MyTestActivity onCreate size=${binder.getData()?.size}")
    }
}

 

MainActivity启动后，MyTestActivity成功收到通过Bundle传输的超大数据集：
