[英]Sending notification does not work
I'm writing an app having minSdkVersion = 9
and maxSdkVersion = 21
. 我正在编写一个具有minSdkVersion = 9
和maxSdkVersion = 21
的应用程序。 In service
I have written a code to send notification, user will be notified when pre-set time matches current time. 在service
我编写了一个发送通知的代码,当预先设定的时间与当前时间匹配时,将通知用户。
However, it notifies me perfectly if I run it in emulator having API = 19 but if I run in my device having API = 10 it does not notify me and crashes the app. 但是,如果我在API = 19的模拟器中运行它,它会完美地通知我,但如果我在我的设备中运行API = 10,它不会通知我并崩溃应用程序。
I'm using Android-Studio in Ubuntu, it doesn't provide device debugging feature. 我在Ubuntu中使用Android-Studio,它不提供设备调试功能。 So I can't even see the logcat
. 所以我甚至看不到logcat
。
Here is my relevant code 这是我的相关代码
@Override
public int onStartCommand(Intent intent, int flags, int startId){
// Intent alarmIntent = new Intent(getBaseContext(), TRAlarmScreen.class);
// alarmIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// alarmIntent.putExtras(intent);
// getApplication().startActivity(alarmIntent); */
Bundle extras = intent.getExtras();
int id = extras.getInt("id");
String title = extras.getString("title");
String des = extras.getString("des");
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setContentTitle(title);
mBuilder.setContentText(des);
mBuilder.setTicker("New Message Alert!");
mBuilder.setSmallIcon(R.drawable.tr);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(id, mBuilder.build());
return START_STICKY;
}
What is the issue? 有什么问题? Do I need to add any support library or something to make it work in lower API levels? 我是否需要添加任何支持库或其他东西才能使其在较低的API级别下工作?
The error is 错误是
java.lang.IllegalArgumentException: contentIntent required: pkg=com.android.saathi id=1 notification=Notification(vibrate=null,sound=null,defaults=0x0,flags=0x0) java.lang.IllegalArgumentException:需要contentIntent:pkg = com.android.saathi id = 1 notification = Notification(vibrate = null,sound = null,defaults = 0x0,flags = 0x0)
My logcat
while running in device having api 10 我在使用api 10的设备中运行时的logcat

在NotificationCompat.Builder
上调用setContentIntent()
,以指示当用户点击Notification
时应该发生什么。
I think I had that same Error. 我想我有同样的错误。 you need to put a PendingIntent in the setContentIntent()
(like what the selected answer said) 你需要在setContentIntent()
放置一个PendingIntent(就像所选答案所说的那样)
in your case like this : 在你的情况下像这样:
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setContentTitle(title);
mBuilder.setContentText(des);
mBuilder.setTicker("New Message Alert!");
mBuilder.setSmallIcon(R.drawable.tr);
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
this,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(id, mBuilder.build());
