我尝试使用由 alexbirkett 编辑的 commonsware 的 locationpoller，但有时广播超时并终止应用程序
这是我的日志

这里是我的实现
PERIOD = SharedPreference.getInt("georef_intervallo", appConfig.georef_intervallo);
mgr =(AlarmManager)getSystemService(ALARM_SERVICE);
Intent i = new Intent(this, LocationPoller.class);
Bundle bundle = new Bundle();
LocationPollerParameter parameter = new LocationPollerParameter(bundle);
parameter.setIntentToBroadcastOnCompletion(new Intent(this, LocationReceiver.class));
// try GPS and fall back to NETWORK_PROVIDER
parameter.setProviders(new String[] {LocationManager.GPS_PROVIDER, LocationManager.NETWORK_PROVIDER});
parameter.setTimeout(60000); //questo è il timeout di check dopo il quale scala sul lastknowlocation
i.putExtras(bundle);
pi = PendingIntent.getBroadcast(this, 0, i, 0);
mgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime(),
PERIOD,
pi);
这里是 locationreceiver.java
package com.sitrade;

public class LocationReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
Log.d("rss","receive");
AppConfig appConfig = new AppConfig();
SharedPreferences SharedPreference = context.getSharedPreferences(appConfig.sharedpreference_key, Context.MODE_PRIVATE);
if ( SharedPreference.getBoolean("georef_active",true) && SharedPreference.getBoolean("DB_DOWNLOADED", false) && SharedPreference.getBoolean("USER_LOGGED",false) ) {
Network = new Network( context );
DatabaseHelper = new DatabaseHelper( context );
Log.i("rss","ricevo la location");
Bundle b=intent.getExtras();
LocationPollerResult locationResult = new LocationPollerResult(b);
Location loc=locationResult.getLocation();
String msg;
if ( loc == null ) {
loc = locationResult.getLastKnownLocation();
if ( loc == null ) {
msg = locationResult.getError();
}
else {
msg = "TIMEOUT, lastKnown="+loc.toString();
}
}
else {
msg = loc.toString();
}
if ( msg == null ) {
msg = "Invalid broadcast received!";
}
else {
Network.appSendGeo(loc);
DatabaseHelper.insertFRONT_GeoTracking(loc);
}
Log.i("rss","*LOCATION RESPONSE:"+msg);
}
else{
Log.d("rss","localion is down");
}
}
}
我不明白这是怎么回事!!
更新 02/04 现在问题消失了，谢谢!但是出现这个

最佳答案
我的猜测是:
Network.appSendGeo(loc);
DatabaseHelper.insertFRONT_GeoTracking(loc);
分别在做网络I/O和磁盘I/O。如果是这样，您需要将这些内容从 BroadcastReceiver 中移出，并移入由 BroadcastReceiver 启动的 IntentService 中。您在主应用程序线程上执行网络 I/O 和磁盘 I/O，最终 Android 假定您的 BroadcastReceiver 已损坏。
