为什么在BOOT_COMPLETED之后不启动服务?

alarmmanager broadcastreceiver service android

crickpatel0024 · 技术社区 · 9 年前

我添加了我的后台服务,但我的手机关闭并打开,然后我的接收器类在get action android.intent.action.BOOT_COMPLETED中运行。但服务未启动。我下面的代码请帮助我!!!

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");
            }
    }

我还在manifeast中添加了权限。

也许你打错了,但如果你想做到这一点 Intent 您应该致电的工作:

context.startService(alarmIntent);

如果这个日志 Log.v("log_tag", "Action :: "+intent.getAction()); 在你的Logcat上显示了请这个 Log.v("log_tag", "REPEAT"); 也

我建议你 BroadcastReceiver 将是这样的:

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 在您的 onCreate 您的 服务 添加以下内容:

/* 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");

我还建议您创建一个新的 广播接收机 在上面做你想重复的事情,并替换 whatever.class 由您的 BroadccastReceiver .

您的应用程序可能安装在外部存储上,它无法接收启动完成事件。您应该添加 android:installLocation="internalOnly" 在你的舱单上。
