请求推送通知的许可

问题描述 投票：0回答：8

我正在开发一个应用程序，我需要使用推送通知。我知道推送通知是正常权限，因此我无法在运行时询问它。但我会在用户下载并安装应用程序时插入权限，以及应用程序应发送推送通知的通知。

我该怎么做？我必须在清单中插入一些东西吗？

2022 年更新

我们在 Android 上请求权限的方式在 Android 13 中发生了巨大变化。请参阅下面提及相同内容的其他答案。

如此处所回答，您不需要推送通知的权限。

其实推送通知权限属于普通类别 类似 Internet 权限，不属于危险类别 许可。

您无需请求推送通知权限。

虽然联系人/位置是危险的权限，因为您 访问用户数据。所以总是需要请求用户允许。

以下是新更新的答案： 在 API 33 中，我们需要推送通知的运行时权限： 完整的文档可以在这里找到，但是你可以简单地使用如下：

在应用程序级别：

<uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>

您可以使用以下命令触发提示：

pushNotificationPermissionLauncher.launch(android.Manifest.permission.POST_NOTIFICATIONS)

处理通知结果：

private val pushNotificationPermissionLauncher = registerForActivityResult(RequestPermission()) { granted ->
            viewModel.inputs.onTurnOnNotificationsClicked(granted)
        }

以下是如何在 Android 13 (Tiramisu) 中请求通知运行时权限的完整示例

首先，在您的

manifest
文件中添加以下权限

<uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>

使用以下代码请求运行时权限

package com.example.myapplication

import android.app.NotificationChannel
import android.app.NotificationManager
import android.content.Context
import android.content.Intent
import android.content.pm.PackageManager
import android.graphics.BitmapFactory
import android.graphics.Color
import android.net.Uri
import android.os.Build
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS
import android.widget.Button
import android.widget.Toast
import androidx.activity.result.contract.ActivityResultContracts
import androidx.core.app.NotificationCompat
import com.google.android.material.dialog.MaterialAlertDialogBuilder

class MainActivity : AppCompatActivity() {

    private val notificationPermissionLauncher =
        registerForActivityResult(ActivityResultContracts.RequestPermission()) { isGranted ->
            hasNotificationPermissionGranted = isGranted
            if (!isGranted) {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    if (Build.VERSION.SDK_INT >= 33) {
                        if (shouldShowRequestPermissionRationale(android.Manifest.permission.POST_NOTIFICATIONS)) {
                            showNotificationPermissionRationale()
                        } else {
                            showSettingDialog()
                        }
                    }
                }
            } else {
                Toast.makeText(applicationContext, "notification permission granted", Toast.LENGTH_SHORT)
                    .show()
            }
        }

    private fun showSettingDialog() {
        MaterialAlertDialogBuilder(this, com.google.android.material.R.style.MaterialAlertDialog_Material3)
            .setTitle("Notification Permission")
            .setMessage("Notification permission is required, Please allow notification permission from setting")
            .setPositiveButton("Ok") { _, _ ->
                val intent = Intent(ACTION_APPLICATION_DETAILS_SETTINGS)
                intent.data = Uri.parse("package:$packageName")
                startActivity(intent)
            }
            .setNegativeButton("Cancel", null)
            .show()
    }

    private fun showNotificationPermissionRationale() {

        MaterialAlertDialogBuilder(this, com.google.android.material.R.style.MaterialAlertDialog_Material3)
            .setTitle("Alert")
            .setMessage("Notification permission is required, to show notification")
            .setPositiveButton("Ok") { _, _ ->
                if (Build.VERSION.SDK_INT >= 33) {
                    notificationPermissionLauncher.launch(android.Manifest.permission.POST_NOTIFICATIONS)
                }
            }
            .setNegativeButton("Cancel", null)
            .show()
    }

    var hasNotificationPermissionGranted = false

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        findViewById<Button>(R.id.btnRequestPermission).setOnClickListener {
            if (Build.VERSION.SDK_INT >= 33) {
                notificationPermissionLauncher.launch(android.Manifest.permission.POST_NOTIFICATIONS)
            } else {
                hasNotificationPermissionGranted = true
            }
        }
        findViewById<Button>(R.id.btnShowNotification).setOnClickListener {
            if (checkSelfPermission(android.Manifest.permission.POST_NOTIFICATIONS) == PackageManager.PERMISSION_GRANTED) {
                showNotification()
            }
        }
    }

    private fun showNotification() {

        val channelId = "12345"
        val description = "Test Notification"

        val notificationManager =
            getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val notificationChannel =
                NotificationChannel(channelId, description, NotificationManager.IMPORTANCE_HIGH)
            notificationChannel.lightColor = Color.BLUE

            notificationChannel.enableVibration(true)
            notificationManager.createNotificationChannel(notificationChannel)

        }

        val  builder = NotificationCompat.Builder(this, channelId)
            .setContentTitle("Hello World")
            .setContentText("Test Notification")
            .setSmallIcon(R.drawable.ic_launcher_foreground)
            .setLargeIcon(
                BitmapFactory.decodeResource(
                    this.resources, R.drawable
                        .ic_launcher_background
                )
            )
        notificationManager.notify(12345, builder.build())
    }
}

如果您使用jetpack compose，则使用以下代码

class MainActivity : ComponentActivity() {

  @RequiresApi(VERSION_CODES.M)
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContent {
      JetpackComposeNotifcationPermissionTheme {
        val context = LocalContext.current
        val permissionOpenDialog = remember { mutableStateOf(false) }
        val rationalPermissionOpenDialog = remember { mutableStateOf(false) }

        if (permissionOpenDialog.value) {
          ShowSettingDialog(openDialog = permissionOpenDialog)
        }

        var hasNotificationPermission by remember {
          if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
            mutableStateOf(
              ContextCompat.checkSelfPermission(
                context,
                Manifest.permission.POST_NOTIFICATIONS
              ) == PackageManager.PERMISSION_GRANTED
            )
          } else mutableStateOf(true)
        }

        val launcher = rememberLauncherForActivityResult(
          contract = ActivityResultContracts.RequestPermission(),
          onResult = { isGranted ->
            if (!isGranted) {
              if (shouldShowRequestPermissionRationale(Manifest.permission.POST_NOTIFICATIONS)) {
                rationalPermissionOpenDialog.value = true
              } else {
                permissionOpenDialog.value = true
              }
            } else {
              hasNotificationPermission = isGranted
            }
          }
        )
        if (rationalPermissionOpenDialog.value) {
          ShowRationalPermissionDialog(openDialog = rationalPermissionOpenDialog) {
            rationalPermissionOpenDialog.value = false
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
              launcher.launch(Manifest.permission.POST_NOTIFICATIONS)
            }
          }
        }


        Column(
          modifier = Modifier.fillMaxSize(),
          verticalArrangement = Arrangement.Center,
          horizontalAlignment = Alignment.CenterHorizontally
        ) {
          Button(onClick = {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
              launcher.launch(Manifest.permission.POST_NOTIFICATIONS)
            }
          }) {
            Text(text = "Request permission")
          }
          Button(onClick = {
            if (hasNotificationPermission) {
              showNotification()
            }
          }) {

      val notificationChannel =
        NotificationChannel(channelId, description, NotificationManager.IMPORTANCE_HIGH)
      notificationChannel.lightColor = Color.BLUE

      notificationChannel.enableVibration(true)
      notificationManager.createNotificationChannel(notificationChannel)
    }
    val notification = NotificationCompat.Builder(applicationContext, channelId)
      .setSmallIcon(R.drawable.ic_launcher_foreground)

如果您的应用面向 Android 13 (Tiramisu) 或更高版本，则必须声明 POST_NOTIFICATIONS 权限，如下所示：

<uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>

有关更多详细信息，请参阅 Android 开发人员文档中的通知运行时权限页面。

我使用https://github.com/zoontek/react-native-permissions

import {requestNotifications} from 'react-native-permissions';

await requestNotifications(['alert', 'badge', 'sound']);

并添加

<uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>

到 androidManifest.xml

试试这个：

在您的 Activity 类中，添加以下代码：

private static final int NOTIFICATION_PERMISSION_CODE = 123;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_activity);

    requestNotificationPermission();

    // Some code
}

 private void requestNotificationPermission() {
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_NOTIFICATION_POLICY) == PackageManager.PERMISSION_GRANTED)
        return;

    if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_NOTIFICATION_POLICY)) {

    }

    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_NOTIFICATION_POLICY}, NOTIFICATION_PERMISSION_CODE );
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

    // Checking the request code of our request
    if (requestCode == NOTIFICATION_PERMISSION_CODE ) {

        // If permission is granted
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // Displaying a toast
            Toast.makeText(this, "Permission granted now you can read the storage", Toast.LENGTH_LONG).show();
        } else {
            // Displaying another toast if permission is not granted
            Toast.makeText(this, "Oops you just denied the permission", Toast.LENGTH_LONG).show();
        }
    }
}
