记录一次session安装应用recyclerview更新数据的bug

首先抛出异常日志，在

先说结论：因为session安装监听是在点击事件里面，所以会保留旧的对象数据

直接上代码，原有的逻辑是点击时执行session安装，并注册监听回调

  private fun installApk(position: Int) {
        val packageInstaller = packageManager.packageInstaller
        val params =
            PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL)
        params.setSize(File(itemList[position].path).length())
        val sessionId = packageInstaller.createSession(params)
        val session = packageInstaller.openSession(sessionId)
        // 注册安装进度监听器
        val sessionCallback = object : PackageInstaller.SessionCallback() {
            override fun onCreated(sessionId: Int) {
                // 安装会话创建成功
                Log.i("InstallProgress", "Session created: $sessionId")
            }
            override fun onProgressChanged(sessionId: Int, progress: Float) {
                // 安装进度更新
                itemList[mPosition].installed = 1
                itemList[mPosition].progress = progress * 100
                adapter.notifyItemChanged(mPosition)
                Log.d(
                    "install",
                    "onProgressChanged: $mPosition ${itemList[mPosition].installed} $progress"
                )
            }
            override fun onFinished(sessionId: Int, success: Boolean) {
                if (success) {
                    // 安装成功
                    itemList[mPosition].installed = 2
                } else {
                    // 安装失败
                    itemList[mPosition].installed = 3
                }
                adapter.notifyItemChanged(mPosition)
                Log.d(
                    "install",
                    "onProgressChanged: $mPosition ${itemList[mPosition].installed} $success"
                )
            }
            override fun onActiveChanged(sessionId: Int, active: Boolean) {
                // 安装会话激活状态发生变化
            }
            override fun onBadgingChanged(sessionId: Int) {
                // 应用图标发生变化
            }
        }
        // 注册监听器
        packageManager.packageInstaller.registerSessionCallback(sessionCallback)
        try {
            val inputStream = FileInputStream(itemList[position].path)
            val outputStream = session.openWrite("base.apk", 0, -1) // -1 表示自动计算大小
            inputStream.copyTo(outputStream)
            session.fsync(outputStream)
            inputStream.close()
            outputStream.close()
            val intent = Intent(context, PackageInstallReceiver::class.java).apply {
                action = itemList[position].pkg
                putExtra(PackageInstaller.EXTRA_PACKAGE_NAME, itemList[position].pkg)
            }
            val pendingIntent = PendingIntent.getBroadcast(
                context,
                0,
                intent,
                PendingIntent.FLAG_UPDATE_CURRENT
            )
            session.commit(pendingIntent.intentSender)
        } catch (e: IOException) {
            session.abandon()
            e.printStackTrace()
        }
    }

修改后，将监听注册到onCreate中，并

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        // 注册监听器
        packageManager.packageInstaller.registerSessionCallback(sessionCallback)
    }
    // 注册安装进度监听器
    private val sessionCallback = object : PackageInstaller.SessionCallback() {
        override fun onCreated(sessionId: Int) {
            // 安装会话创建成功
            Log.i("InstallProgress", "Session created: $sessionId")
        }
        override fun onProgressChanged(sessionId: Int, progress: Float) {
            // 安装进度更新
            itemList[mPosition].installed = 1
            itemList[mPosition].progress = progress * 100
            adapter.notifyItemChanged(mPosition)
            Log.d("installApk", "onProgressChanged: $mPosition ${itemList[mPosition].installed} $progress")
        }
        override fun onFinished(sessionId: Int, success: Boolean) {
            if (success) {
                // 安装成功
                itemList[mPosition].installed = 2
            } else {
                // 安装失败
                itemList[mPosition].installed = 3
            }
            adapter.notifyItemChanged(mPosition)
            Log.d("installApk", "onProgressChanged: $mPosition ${itemList[mPosition].installed} $success")
        }
        override fun onActiveChanged(sessionId: Int, active: Boolean) {
            // 安装会话激活状态发生变化
        }
        override fun onBadgingChanged(sessionId: Int) {
            // 应用图标发生变化
        }
    }
    private fun installApk(position: Int) {
        val packageInstaller = packageManager.packageInstaller
        val params =
            PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL)
        params.setSize(File(itemList[position].path).length())
        val sessionId = packageInstaller.createSession(params)
        val session = packageInstaller.openSession(sessionId)
        try {
            val inputStream = FileInputStream(itemList[position].path)
            val outputStream = session.openWrite("base.apk", 0, -1) // -1 表示自动计算大小
            inputStream.copyTo(outputStream)
            session.fsync(outputStream)
            inputStream.close()
            outputStream.close()
            val intent = Intent(context, PackageInstallReceiver::class.java).apply {
                action = itemList[position].pkg
                putExtra(PackageInstaller.EXTRA_PACKAGE_NAME, itemList[position].pkg)
            }
            val pendingIntent = PendingIntent.getBroadcast(
                context,
                0,
                intent,
                PendingIntent.FLAG_UPDATE_CURRENT
            )
            session.commit(pendingIntent.intentSender)
        } catch (e: IOException) {
            session.abandon()
            e.printStackTrace()
