无法启动活动：java.lang.IllegalArgumentException：定位 S+（版本 31 及更高版本）需要 FLAG_IMMUTABLE 或 FLAG_MUTABLE 之一

Question

今天我的手机更新到 android 12，我的应用在启动时开始崩溃。它应该在启动时发送通知。

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志，但调试器在“PendingIntent.getActivity”行中说明了如下错误。

这是我姐姐的一个紧急应用程序，所以我很感激你的帮助。谢谢。

Answer 1

你这样做：

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

您还必须将FLAG_IMMUTABLE 或FLAG_MUTABLE 添加到此。

Answer 2

你需要做的是： 放入你的 build.gradle

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

去编辑>查找>在文件中查找并搜索PendingIntent，如果你使用java代码放|PendingIntent.FLAG_IMMUTABLE如果Kotlin然后或PendingIntent.FLAG_IMMUTABLE
