Android意图需要很长时间才能收到

在我的应用程序中,我发送更新appWidget的意图。问题是,从logcat我可以看到意图平均需要十秒钟才能收到。

我看到的唯一看起来有点可疑的是警告活动正在开始。为什么会出现警告?除此之外,一切似乎都没问题。

发送意图的代码并不特别:

    Log.d(MY_DEBUG_TAG, "UpdateAppWidgets()");
    Intent i = new Intent();
    i.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
    ComponentName phcaWidget = new ComponentName(ctx, PhcaAppWidgetProvider.class);
    i.putExtra("appWidgetIds", AppWidgetManager.getInstance(ctx).getAppWidgetIds(phcaWidget));

    ctx.sendBroadcast(i);
    Log.d(MY_DEBUG_TAG, "Broadcast sent");

appWidgetProvider中的onReceive也没什么特别的。 Log语句是第一个命令。

什么可能导致意图花费超过十秒钟的时间?

如果您要发送意图的活动尚不存在,则必须启动它。 10秒似乎很长一段时间来启动应用程序,但不是疯了。

我在调试模式下运行5次或更慢的应用程序。如果您处于调试模式,那么如果不是在调试模式下,它可能会运行得更快。通常,对于连接到运行eclipse IDE的PC的设备,您可以在不处于调试模式时看到logcat消息。如果你可以做到这一点,你应该尝试以这种方式运行,看看它是否更快。同时尝试完全从Eclipse拔掉电话运行,更难判断它是否更快但可能更快。
