android app在android 2.3.3中工作正常，但在android 4.1.2中停止

Question

Mine is an android tracking app. It gets gps location and send it to server. if gps location is not found it gets location using cell id. It works fine in android 2.3.3 . It also works in android 4.1.2 but stops after some time(2hrs or 8 hrs,sometimes 1 day), without any force close message. I googled but didn't find the error. Are any methods deprecated in 2.3.3. Below is my code. the service is started repeatedly by the BroadcastReceiver which is started by AlarmManager .
I have written this in my manifest file:

<uses-sdk android:minSdkVersion="7" 
    android:targetSdkVersion="18"/>

GPSLoggerService class:

public class GPSLoggerService extends Service implements LocationListener {
    @Override

        AppLog.logString("GPSLoggerService.onCreate().");
        data_mode = settings.getInt("data_mode", 1);
        boolean firstRecordAfterBoot = settings.getBoolean("justBooted", false);

        settings.edit().putBoolean("justBooted", false);

        super.onCreate();
        // db = new DBAdapter(this);
    }

    public int onStartCommand(Intent intent, int flags, int startId) {
        appendLog("in onStartCommend, ");
        AppLog.logString("GPSLoggerService.onStartCommand().");

        startLoggingService();

Answer 1

try to use this code in onCreate method.

int SDK_INT = android.os.Build.VERSION.SDK_INT;

if (SDK_INT>8){

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();

StrictMode.setThreadPolicy(policy); 

}

and Set the Android Manifest to something like this

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" android:maxSdkVersion="16"/>
