Android 在版本 S+ 中创建通知时应用崩溃
Android app crashing while creating notifications in Version S+
我在我的应用程序中使用通知已经有一段时间了，一切正常，直到我最近定位到 android 12。现在，当我在 android 12 上收到通知时，我的应用程序崩溃了。但在 android 12 台设备上一切正常。这是我到目前为止尝试过的方法。
AlarmReceiver.java
public class AlarmReceiver extends BroadcastReceiver {
private static final String CHANNEL_ID = "1";
private static final String CHANNEL_NAME = "Notifications";
@Override
public void onReceive(Context context, Intent intent) {
// For android 8 and above
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
channel.setDescription(context.getString(R.string.notifications));
channel.enableLights(true);
channel.enableVibration(true);
channel.setLightColor(Color.RED);
channel.setShowBadge(true);
channel.setLockscreenVisibility(NotificationCompat.VISIBILITY_PUBLIC); //Show notification on lock screen
NotificationManager manager = context.getSystemService(NotificationManager.class);
assert manager != null;
manager.createNotificationChannel(channel);
}
Cursor cursor = new DatabaseHelper(context).generateNotification();
if (cursor.moveToFirst()) {
// Create an Intent for the activity you want to start
Intent newIntent = new Intent(context, MainActivity.class);
newIntent.putExtra(Constants.STRING_EXTRA_INCOMING_ACTIVITY, Constants.ACTIVITY_NOTIFICATION);
newIntent.putExtra(Constants.STRING_EXTRA_QUOTE, cursor.getString(1));
// on back pressed go back to main activity
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addNextIntentWithParentStack(newIntent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
// Build Notification
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_notification)
.setColor(Color.parseColor("#ffa000"))
.setContentTitle(context.getString(R.string.notifications))
.setContentText(Html.fromHtml(cursor.getString(1)))//builds the title from columns of the selected row
.setContentIntent(pendingIntent) // On Notification Click Goto DetailActivity
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setAutoCancel(true);
NotificationManagerCompat managerCompat = NotificationManagerCompat.from(context);
managerCompat.notify(1, mBuilder.build());
} else {
Toast.makeText(context, "Unable To Generate Notification", Toast.LENGTH_LONG).show();
}
cursor.close();
}
}
这是在我的 MainActivity 中显示通知的代码
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this,
0, intent, PendingIntent.FLAG_IMMUTABLE);
AlarmManager alarms = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
Calendar now = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 8);
calendar.set(Calendar.MINUTE, 10);
if (now.after(calendar)) {
calendar.add(Calendar.DATE, 1);
}
if (alarms != null) {
alarms.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, pendingIntent);
}
}
这是我在 firebase 上收到的崩溃报告

根据官方文档“如果您的应用面向 Android 12，您必须指定您的应用创建的每个 PendingIntent 对象的可变性。此附加要求提高了您应用的安全性。"
Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context,NOTIFICATION_REQUEST_CODE, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_IMMUTABLE);
我们正在构建一个标准类型的 Intent 来打开我们的应用程序，然后简单地将其包装在 PendingIntent 中，然后再将其添加到我们的 notification.In 这种情况下，因为我们有一个确切的动作，我们知道我们想要执行，我们构建一个 PendingIntent，我们通过使用名为 FLAG_IMMUTABLE.
的标志，将其传递给的应用程序无法对其进行修改
