為什么在BOOT_COMPLETED之后服務無法啟動？

Question

我添加了我的后台服務，但我的手機運行正常，但是我的手機關閉了，然后再打開，然后在接收器類中執行android.intent.action.BOOT_COMPLETED。，但是服務無法啟動。我的下面的代碼請幫幫我！

public class ReceiverCall extends BroadcastReceiver {
    static final String ACTION = "android.intent.action.BOOT_COMPLETED";
    static final String ACTION1 = "android.intent.action.QUICKBOOT_POWERON";
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.v("log_tag", "Action :: "+intent.getAction());
         if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
                /* Setting the alarm here */
                Intent alarmIntent = new Intent(context, MyAlarmService.class);
                PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);
                AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
                Calendar calendar = Calendar.getInstance();
                calendar.setTimeInMillis(System.currentTimeMillis());
                manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), + (1000 * 60 * 2), pendingIntent);
                Log.v("log_tag", "REPEAT");
            }
    }

而且我還要在清單中添加權限。

也許您輸錯了類型，但是如果您想使Intent發揮作用，您應該致電：

context.startService(alarmIntent);

並且讓我知道此日志Log.v("log_tag", "Action :: "+intent.getAction()); 在您的Logcat上顯示的是這個Log.v("log_tag", "REPEAT"); 太。

我建議您的BroadcastReceiver應該是這樣的：

public class ReceiverCall extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    Log.v("log_tag", "Action :: "+intent.getAction());
     if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
            //make an intent to your Service as follows 
            Intent serviceIntent = new Intent(context, MyAlarmService.class);
            context.startService(serviceIntent);
        }
}

然后在你的Service在您onCreate您的Service補充一點：

/* Setting the alarm here */
Intent alarmIntent = new Intent(context, Whatever.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);
AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), + (1000 * 60 * 2), pendingIntent);
Log.v("log_tag", "REPEAT");

我也建議你創建一個新的BroadcastReceiver和它做你的東西，你要重復，並更換whatever.class你BroadccastReceiver 。

您的應用安裝在外部存儲設備上的機會，可能無法收到啟動完成事件。 您應該在清單中添加android:installLocation="internalOnly" 。
