Android AlarmManagerがWakeLock付きでもWakeLockなしでも

Question

私はしばらくの間、簡単なアラームアプリを作ろうとしていましたが、WakeLockの有無にかかわらず、 ）。 AlarmReceiverについては

public class MainActivity extends AppCompatActivity { 
    public final int sleepRequest = 111; 
    public final int wakeRequest = 222; 

    PendingIntent pendingIntent; 
    AlarmManager manager; 

    // currently no difference between sleeping and waking alarms, nor do the alarms use the selected time 

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

     Button sleepButton = (Button) findViewById(R.id.sleepButton); 
     sleepButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       createAlarm(sleepRequest); 
      } 
     }); 

     Button wakeButton = (Button) findViewById(R.id.wakeButton); 
     wakeButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       createAlarm(wakeRequest); 
      } 
     }); 
    } 

    public void createAlarm(final int requestCode) { 
     showTimePicker(new Completion() { 
      @Override 
      public void onCompletion(int hour, int minute) { 
       setAlarm(hour, minute, requestCode); 
      } 
     }); 
    } 

    public void showTimePicker(final Completion completion) { 
     Calendar calendar = Calendar.getInstance(); 
     int hour = calendar.get(Calendar.HOUR_OF_DAY); 
     int minute = calendar.get(Calendar.MINUTE); 

     TimePickerDialog timePickerDialog = new TimePickerDialog(this, 
       new TimePickerDialog.OnTimeSetListener() { 
        @Override 
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 
         completion.onCompletion(hourOfDay, minute); 
        } 
       }, hour, minute, false); 
     timePickerDialog.show(); 
    } 

    public void setAlarm(int hour, int minute, int requestCode) { 
     Date date = new Date(); 
     Calendar now = Calendar.getInstance(); 
     now.setTime(date); 

     Calendar alarm = Calendar.getInstance(); 
     alarm.setTime(date); 
     alarm.set(Calendar.HOUR_OF_DAY, hour); 
     alarm.set(Calendar.MINUTE, minute); 
     alarm.set(Calendar.SECOND,0); 

     if(alarm.before(now)){ 
      alarm.add(Calendar.DATE,1); 
     } 

     manager = (AlarmManager) getSystemService(ALARM_SERVICE); 
     Intent intent = new Intent(MainActivity.this, AlarmReceiver.class); 
     pendingIntent = PendingIntent.getBroadcast(MainActivity.this, requestCode, intent, 0); 
     manager.setAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, alarm.getTimeInMillis(), pendingIntent); 
    } 
} 

：アラームサービスについては

public class AlarmReceiver extends WakefulBroadcastReceiver { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
     Intent service = new Intent(context, AlarmService.class); 
     Log.i("SimpleWakefulReceiver", "Starting service @ " + SystemClock.elapsedRealtime()); 
     startWakefulService(context, service); 
    } 
} 

：これはMainActivityのために私のコードです

public class AlarmService extends IntentService { 
    public AlarmService() { 
     super("AlarmService"); 
    } 

    @Override 
    protected void onHandleIntent(Intent intent) { 
     Log.i("APP", "in onHandleIntent"); 
     Toast.makeText(getApplicationContext(), "Hello world", Toast.LENGTH_SHORT).show(); 
    } 
} 

そして、これはAndroidManifestです：それは達すると

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

    <uses-permission android:name="android.permission.WAKE_LOCK" /> 
    <uses-permission android:name="com.android.alarm.permission.SET_ALARM" /> 

    <application 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher" 
     android:label="@string/app_name" 
     android:supportsRtl="true" 
     android:theme="@style/AppTheme"> 

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

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

     <service android:name=".AlarmService" /> 

    </application> 

</manifest> 

時間あなたはWakefulBroadcastReceiverが何をするのか混乱している

Answer 1

：アラームがオフに行くことになっている、私はこのエラーを取得します。それは画面をオンにしません。それはプロセッサを起動させます。画面をオンにしたい場合は、普通の放送受信機を使用し、WAKELOCKを完全に取る必要があります。WAKELLBroadcastReceiverが取るWAKELOCKは部分的なものです。
