here's code:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"           package="com.guoyonghui.todo"           android:installlocation="auto">      <uses-permission android:name="android.permission.vibrate"/>     <uses-permission android:name="android.permission.wake_lock"/>     <uses-permission android:name="android.permission.receive_boot_completed"/>      <application         android:name=".baseapplication"         android:allowbackup="true"         android:icon="@mipmap/ic_launcher"         android:label="@string/app_name"         android:supportsrtl="true"         android:theme="@style/apptheme">         <activity android:name=".tasks.tasksactivity">             <intent-filter>                 <action android:name="android.intent.action.main"/>                  <category android:name="android.intent.category.launcher"/>             </intent-filter>         </activity>         <activity android:name=".taskdetail.taskdetailactivity"/>         <activity android:name=".addedittask.addedittaskactivity"/>         <activity android:name=".statistics.statisticsactivity"/>          <receiver android:name=".alarm.alarmreceiver">             <intent-filter>                 <action android:name="com.guoyonghui.todo.alarm.action_task_alarm"/>             </intent-filter>         </receiver>         <receiver             android:name=".alarm.bootreceiver"             android:enabled="true">             <intent-filter>                 <action android:name="android.intent.action.boot_completed"/>                 <action android:name="android.intent.category.default"/>             </intent-filter>         </receiver>     </application>  </manifest>  public class bootreceiver extends broadcastreceiver {      @override     public void onreceive(context context, intent intent) {         string action = intent.getaction();          toast.maketext(context, action, toast.length_short).show();         log.d("alarmreceiver", action);          if (intent.action_boot_completed.equals(action)) {             tasksrepository tasksrepository = tasksrepository.getinstance(taskslocaldatasource.getinstance(context));             list<task> tasks = tasksrepository.loadtasks();             (task task : tasks) {                 if (task.isactive()) {                     alarmreceiver.setalarm(context, task);                 }             }         }     } } 

you don't want use default category in case. according documentation of category, used following purpose:

set if activity should option default action (center press) perform on piece of data. setting hide user activities without set when performing action on data. note -not- set in intent when initiating action -- use in intent filters specified in packages. (emphasis mine)

see list of categories , they're here: https://developer.android.com/reference/android/content/intent.html
