无法启动活动：java.lang.IllegalArgumentException:针对S+（版本31及以上）的目标需要FLAG_IMMUTABLE或FLAG_MUTABLE中的一个。

Question

今天我的手机更新到了Android 12系统，我打开一个应用程序时，它开始崩溃。该应用程序在启动时应该发送通知。

val intent = Intent(this, MainActivity::class.java)
        val pendingIntent: PendingIntent? = TaskStackBuilder.create(this).run {
            addNextIntentWithParentStack(intent)
            getPendingIntent(INTENT_REQUEST, PendingIntent.FLAG_IMMUTABLE) //Used to be: FLAG_UPDATE_CURRENT
        }

        //Configurar llamada desde boton de notificacion
        val buttonIntent = Intent(this, LlamadaNotificacion::class.java)
        buttonIntent.putExtra("LLAMADA", "LLAMAR")

        val buttonPendingIntent: PendingIntent =
            PendingIntent.getActivity(this, BUTTON_INTENT_REQUEST, buttonIntent, PendingIntent.FLAG_ONE_SHOT)

        val boton = NotificationCompat.Action.Builder(
            R.drawable.dry,"Presiona para realizar llamada de emergencia", buttonPendingIntent
        ).build()

        val notification = NotificationCompat.Builder(this,channelID).also {
            it.setContentTitle("Daira Mayari Mendez Gutierrez")
            it.setContentText("Presiona para más información")
            it.setSmallIcon(R.mipmap.ic_logo)
            //it.setPriority(NotificationCompat.PRIORITY_HIGH)
            it.setContentIntent(pendingIntent)
            it.setVisibility(VISIBILITY_PUBLIC)
            it.addAction(boton)
            it.setAutoCancel(false)
        }.build()

        val notificationManager = NotificationManagerCompat.from(this)

        notificationManager.notify(notificationId,notification)

我已经尝试使用可变和不可变标记，但是调试器会在"PendingIntent.getActivity"行显示错误，如下所示。

这是为我患病的姐姐准备的紧急应用程序，所以我非常感谢您的帮助。谢谢。

Answer 1

你需要做这个：

    val buttonPendingIntent: PendingIntent =
        PendingIntent.getActivity(this, BUTTON_INTENT_REQUEST, buttonIntent, PendingIntent.FLAG_ONE_SHOT)

你还需要在这个里面添加FLAG_IMMUTABLE或者FLAG_MUTABLE。

Answer 2

你需要做的是： 在你的 build.gradle 文件中添加以下内容：

def work_version = "2.7.1"
    implementation "androidx.work:work-runtime:$work_version"
    // optional - Test helpers
    androidTestImplementation "androidx.work:work-testing:$work_version"

然后

进入编辑> 查找 > 在文件中查找，搜索 PendingIntent，如果您正在使用 Java 代码，请添加 |PendingIntent.FLAG_IMMUTABLE，如果是 Kotlin，则添加 or PendingIntent.FLAG_IMMUTABLE

您的问题将会被100%解决： 加油！
