android - LocalBroadcastManager 在 2.3 上不接收广播

Question

不适用于 2.3。但适用于 4.0.x。为什么？

从 IntentService 发送：

intent.setAction(MessagesThread.NEW_MESSAGE);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

接收

protected void onStart() {
super.onStart();
LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,new IntentFilter(NEW_MESSAGE));
}

protected void onStop() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(mMessageReceiver);
super.onStop();
}

private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
    .......................................
            .......................................
}
};

Answer 1

LocalBroadcastManager.getInstance(this).sendBroadcast(newIntent(MessagesThread.NEW_MESSAGE).putExtras(intent));

Answer 2

我不确定，但问题可能是由于 LocalBroadcastManager。尝试在不使用 LocalBroadcastManager 的情况下发送广播，如下所示：

发送广播

Intent i = new Intent("ALERT_CHANGE");
i.putExtra("DATA","News");
sendBroadcast(i);

接收广播活动

registerReceiver(uiUpdated, new IntentFilter("ALERT_CHANGE"));


private BroadcastReceiver uiUpdated= new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) 
{
String DATA = i.getStringExtra("Data");
txt.settext(DATA);
}
};
