Android Eclair GPS and AGPS

[lvsei]

Dear all~~

I am porting GPS in android 2.0.
I have encountered a problem about GPS fix mode.
In the code

public void startNavigating() {
if (!mStarted) {
if (DEBUG) Log.d(TAG, "startNavigating");
mStarted = true;
int positionMode;
if (Settings.Secure.getInt(mContext.getContentResolver(),
Settings.Secure.ASSISTED_GPS_ENABLED, 1) != 0) {
positionMode = GPS_POSITION_MODE_MS_BASED;
} else {
positionMode = GPS_POSITION_MODE_STANDALONE;
}

if (!native_start(positionMode, false, mFixInterval)) {
mStarted = false;
Log.e(TAG, "native_start failed in startNavigating
()");
return;
}

// reset SV count to zero
updateStatus(LocationProvider.TEMPORARILY_UNAVAILABLE, 0);
mFixCount = 0;
mFixRequestTime = System.currentTimeMillis();
// set timer to give up if we do not receive a fix within
NO_FIX_TIMEOUT
// and our fix interval is not short
if (mFixInterval >= NO_FIX_TIMEOUT) {
mAlarmManager.set
(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime() + NO_FIX_TIMEOUT
* 1000, mTimeoutIntent);
}
}
}

it always run positionMode = GPS_POSITION_MODE_MS_BASED;

but if I want to run positionMode = GPS_POSITION_MODE_STANDALONE;
How/Where do I configure the settings about GPS fix mode.

I use sqlite command to check /data/data/
com.android.providers.settings/databases/settings.db, it shows message
below

1|bluetooth_on|0
2|data_roaming|0
5|assisted_gps_enabled|1
6|network_preference|1
7|usb_mass_storage_enabled|1
8|wifi_on|0
9|wifi_networks_available_notification_on|1
10|preferred_network_mode|0
11|cdma_cell_broadcast_sms|1
12|preferred_cdma_subscription|1
15|backup_transport|
21|device_provisioned|1
23|install_non_market_apps|1
108|enabled_accessibility_services|
127|backup_enabled|0
128|adb_enabled|1
161|enabled_input_methods|com.android.inputmethod.latin/.LatinIME
162|default_input_method|com.android.inputmethod.latin/.LatinIME
164|mock_location|1
167|location_providers_allowed|gps,network

The assisted_gps_enabled always set to 1. How do I set it to 0 to
use GPS fix mode to standalong;

Best Regard

I'm trying to track down a solution to this exact same problem, does
anyone have any idea on how the default settings int he SQLITE3
database get created during an Android build??

Thanks
