本地广播管理器在 2.3 上不接收广播

Question

不适用于2.3。但可以在4.0.x上运行。为什么?

发送自IntentService:

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

接受

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

我不确定，但问题可能是由于LocalBroadcastManager。尝试不使用LocalBroadcastManager发送广播，如下所示:

发送广播

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

RECEIVE BROADCAST-in Activity

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);
}
};

Answer 2

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