在ANDROID中获取后台网络位置

我在这里从许多线程中研究了如何在Android操作系统中获取位置信息，并尝试了一些设计。然而，我每次都会有大量的电池耗电，只是无法摆脱它。这是我代码的一部分

Java

public class LocationReceiver extends BroadcastReceiver {
public static double latestUpdate = 0;
public static int status = 0;
public static int count_upload = 0;
public static int count_ignored = 0;
public static Geocoder gc;
public void onReceive(Context context, Intent intent) {
    // Do this when the system sends the intent
    Bundle b = intent.getExtras();
    Location loc = (Location) b
            .get(android.location.LocationManager.KEY_LOCATION_CHANGED);
    if (loc == null)
        return;
    if (gc == null)
        gc = new Geocoder(context);
    update(loc, context);
}

public void update(Location loc, Context context) {
    // Here I am checking if 10 minutes passed from last update to now.
    // and if so, I am uploading my location to my server.
    if (latestUpdate != 0
            && latestUpdate + ((LaunchReceiver.interval - 2) * 1000) > SystemClock
                    .elapsedRealtime()) {
        // duplicate (ignore)
        count_ignored++;
    } else {
        // Upload to server on an async task.
        // ...
        LocationReceiver.latestUpdate = SystemClock.elapsedRealtime();
        count_upload++;
    }

}
}

public class LaunchReceiver extends BroadcastReceiver {
public static boolean registered = false;
public static LocationManager lm;
public static int interval = 600000;
public static PendingIntent pendingIntent;
SharedPreferences sharedPrefs = null;

@Override
public void onReceive(Context context, Intent intent) {
    if (registered)
        return;
    sharedPrefs = PreferenceManager.getDefaultSharedPreferences(context);
    interval = Integer.parseInt(sharedPrefs.getString("updates_interval",
            "600000"));
    Intent in = new Intent("bdd.sanalmusavir.LOCATION_READY");
    pendingIntent = PendingIntent.getBroadcast(context, 0, in,
            PendingIntent.FLAG_UPDATE_CURRENT);
    lm = (LocationManager) context
            .getSystemService(Context.LOCATION_SERVICE);
    // Register for broadcast intents
    lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, interval,
            0, pendingIntent);

    registered = true;
}
}

Java

public class LocationReceiver extends BroadcastReceiver {
public static double latestUpdate = 0;
public static int status = 0;
public static int count_upload = 0;
public static int count_ignored = 0;
public static Geocoder gc;
public void onReceive(Context context, Intent intent) {
    // Do this when the system sends the intent
    Bundle b = intent.getExtras();
    Location loc = (Location) b
            .get(android.location.LocationManager.KEY_LOCATION_CHANGED);
    if (loc == null)
        return;
    if (gc == null)
        gc = new Geocoder(context);
    update(loc, context);
}

public void update(Location loc, Context context) {
    // Here I am checking if 10 minutes passed from last update to now.
    // and if so, I am uploading my location to my server.
    if (latestUpdate != 0
            && latestUpdate + ((LaunchReceiver.interval - 2) * 1000) > SystemClock
                    .elapsedRealtime()) {
        // duplicate (ignore)
        count_ignored++;
    } else {
        // Upload to server on an async task.
        // ...
        LocationReceiver.latestUpdate = SystemClock.elapsedRealtime();
        count_upload++;
    }

}
}

public class LaunchReceiver extends BroadcastReceiver {
public static boolean registered = false;
public static LocationManager lm;
public static int interval = 600000;
public static PendingIntent pendingIntent;
SharedPreferences sharedPrefs = null;

@Override
public void onReceive(Context context, Intent intent) {
    if (registered)
        return;
    sharedPrefs = PreferenceManager.getDefaultSharedPreferences(context);
    interval = Integer.parseInt(sharedPrefs.getString("updates_interval",
            "600000"));
    Intent in = new Intent("bdd.sanalmusavir.LOCATION_READY");
    pendingIntent = PendingIntent.getBroadcast(context, 0, in,
            PendingIntent.FLAG_UPDATE_CURRENT);
    lm = (LocationManager) context
            .getSystemService(Context.LOCATION_SERVICE);
    // Register for broadcast intents
    lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, interval,
            0, pendingIntent);

    registered = true;
}
}

AndroidManifest.Xml

<application

        android:label="@string/app_name" >

LocationManager.requestLocationUpdates上的字段minInterval需要毫秒时间。你超过600，这将导致经理每600毫秒或基本上尽可能快地开火。我想你只是少了一个*1000。
这只是为了测试。对不起，我忘了在我的帖子上提到它。我使用的是我的首选项600*1000。修正了我的帖子。
