關機後的鬧鐘管理器

Question

當我試過這段代碼時，一切正常，除非設備重啓後服務沒有啓動。我想自動啓動相同的服務。我正在通過將移動設備與USB連接來測試此示例。我需要改變什麼？ [http://javatechig.com/android/repeat-alarm-example-in-android]

Answer 1

你必須創建一個廣播接收器將偵聽啓動完成事件，當接收到該事件再次開始

<receiver android:name=".Autostart"> 
     <intent-filter> 
      <action android:name="android.intent.action.BOOT_COMPLETED" /> 
     </intent-filter> 
    </receiver> 

您的服務創建一個類，像這樣在的onReceive方法中添加代碼

public class Autostart extends BroadcastReceiver 
{ 
    public void onReceive(Context arg0, Intent arg1) 
    { 
     Log.i("Autostart", "**********started************"); 
    } 
} 

Answer 2

嘗試這樣

<!-- for reboot event to reset alarms --> 
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> 

然後

<receiver 
     android:name="com.yourapp.receiver.RestartAppReceiver" 
     android:enabled="true" 
     android:exported="true"> 
     <intent-filter> 
      <action android:name="android.intent.action.BOOT_COMPLETED" /> 
     </intent-filter> 
    </receiver> 

下次你要創建的BroadcastReceiver類

public class RestartAppReceiver extends BroadcastReceiver { 

    private static final String LOG_TAG = "RestartAppReceiver"; 

    public RestartAppReceiver() { 
    } 

    @Override 
    public void onReceive(Context context, Intent intent) { 

     if (intent != null) { 
      String action = intent.getAction(); 

      switch (action) { 
       case Intent.ACTION_BOOT_COMPLETED: 
        Log.i(LOG_TAG, "Start resetting alarms after reboot"); 


        //restart what you need 


        Log.i(LOG_TAG, "Finish resetting alarms after reboot"); 
        break; 
       default: 
        break; 
      } 
     } 
    } 
}
