单击通知

Question

我在我的应用程序中创建了一个通知设置。当用户点击通知时，假设活动Coding打开。但它不是。当我检查手机日志时（在android工作室的控制台中）它有一些这样的东西：

10-19 19:18:14.598 888-1437/? W/ActivityManager: Permission Denial: starting Intent { flg=0x1000c000 cmp=com.defcomdevs.invento16/.Coding bnds=[0,874][1080,1060] } from null (pid=-1, uid=10169) not exported from uid 10185

我不明白那是什么？ 我的通知代码是：

public class AlarmReceiver extends BroadcastReceiver {
static int notifyId=1;
@Override
public void onReceive(Context context, Intent intent) {
    //Toast.makeText(context,"Alarm has been set",Toast.LENGTH_SHORT).show();
    NotificationCompat.Builder mNotify=new NotificationCompat.Builder(context);
    mNotify.setSmallIcon(R.drawable.index);
    mNotify.setContentTitle("Coding");
    mNotify.setContentText("INVENTO: Coding competition is going to be conducted today.");
    Intent resultIntent=new Intent(context,Coding.class); //activity to open up when user clicks the notification
    TaskStackBuilder stackBuilder=TaskStackBuilder.create(context);
    stackBuilder.addParentStack(Coding.class); //add the to-be-displayed activity to the top of stack
    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
    mNotify.setContentIntent(resultPendingIntent);
    NotificationManager notificationManager=(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(notifyId, mNotify.build());
    Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    Ringtone r = RingtoneManager.getRingtone(context, notification);
    r.play();
    //note: on click display activity is not working.
}
}

请帮助!!

我的manifest.xml文件：

  <?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.defcomdevs.invento16" >

<application

    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity

        android:label="@string/title_activity_alarm"

    </activity>

    <receiver
        android:name=".AlarmReceiver"
        android:process=":remote" />

    <activity
        android:name=".Registration"
        android:label="@string/title_activity_registration"
        android:theme="@style/AppTheme.NoActionBar" >

    <activity

        android:label="@string/title_activity_coding"

将android:exported="true"添加到.Coding文件中的manifest.xml活动代码中。虽然请记住，这允许其他应用程序开始您的活动。
