I do the following function in my main activity
#Override
public void onDestroy() {
super.onDestroy();
SimpleBookManager.getSimpleBookManager().saveChanges(this);
}
When Android later call the method function saveChanges() when I close the Application I get the "SaveChanges" outprint but not the last print "After Saving" meaning that its not executing the whole function and I'm not getting any outPrints on the catch exceptions lines either. Do you know why? I'm new to android and do not understand if you could run this code onDestroy(). =)
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.ArrayList;
import android.content.Context;
public class SimpleBookManager implements BookManager, java.io.Serializable {
private ArrayList<Book> allBooks = new ArrayList<Book>();
private static SimpleBookManager ref;
public void saveChanges(Context context){
try{
System.out.println("SaveChanges");
FileOutputStream f_out = context.openFileOutput("myobject.data",Context.MODE_PRIVATE);
// Write object with ObjectOutputStream
ObjectOutputStream obj_out = new ObjectOutputStream (f_out);
// Write object out to disk
obj_out.writeObject(allBooks);
System.out.println("After Saving");
}catch (FileNotFoundException e) {
System.out.println("No file found saveChanges");
} catch (IOException e) {
System.out.println("IOException in SaveChanges");
}
}
public void loadBooks(Context context){
try{
// Read from disk using FileInputStream
FileInputStream f_in = context.openFileInput("myobject.data");
// Read object using ObjectInputStream
ObjectInputStream obj_in = new ObjectInputStream (f_in);
// Read an object
Object obj = obj_in.readObject();
//System.out.println(obj);
if (obj instanceof ArrayList<?>)
{
allBooks = (ArrayList<Book>) obj;
System.out.println("Worked");
System.out.println(allBooks);
}
}catch (FileNotFoundException e) {
System.out.println("No file found LoadBooks");
} catch (IOException e) {
System.out.println("IOException in loadBooks");
}
catch (ClassNotFoundException e) {
System.out.println("ClassNotFound in loadBooks");
}
}
public static SimpleBookManager getSimpleBookManager()
{
if (ref == null){
ref = new SimpleBookManager();
}
return ref;
}
public SimpleBookManager(){
Book book1 = createBook();
book1.setAuthor("RandomBookAuthor");
book1.setCourse("Kunskap");
book1.setPrice(199);
book1.setTitle("Some Random Title");
book1.setIsbn("9780590353403");
}
}
I also get IOException when doing this onCreate() in main, so something is really fishy about my load and save functions.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SimpleBookManager.getSimpleBookManager().loadBooks(this);
setContentView(R.layout.activity_action_bar_main);
}

Edit
After I followed the advice below I now get a IOException in saveChanges()
And I do set the data correct like this (In SimpleBookManager)
public SimpleBookManager(){
Book book1 = createBook();
book1.setAuthor("RandomBookAuthor");
book1.setCourse("Kunskap");
book1.setPrice(199);
book1.setTitle("Some Random Title");
book1.setIsbn("9780590353403");
}
i think you save the data in onResume meothd it's guarantee the system will make the action before kill the process
Reorder your onCreate() method
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_action_bar_main);
SimpleBookManager.getSimpleBookManager().loadBooks(this);
}
and Override onStop() method and don't override onDestroy method:
#Override
public void onStop() {
super.onStop();
SimpleBookManager.getSimpleBookManager().saveChanges(this);
}

I try this code in other real device. In one device works great but in my device the same code doesn't work. Anyone can help me to understand why?
It looks like twitter is null here
AccessToken at = twitter.getOAuthAccessToken(
requestToken,verifier);
because this method is called before you run your AsyncTask which initializes your twitter variable.
Try calling this method in onPostExecute() of your AsyncTask since this method will be called when doInBackground() is finished.
Hi guys I'm creating simple interactive android application. Server runs Java.
It turns out, that I can not receive files from server.
Android code is following
public class MainActivity extends Activity {
public DataReceiving dataReceiving;
public DataTransfer dataTransfer;
private EditText inputData;
private Button sendParameters;
private Button startComputation;
public TextView displayText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
inputData= (EditText) findViewById(R.id.editText1);
sendParameters=(Button) findViewById(R.id.button1);
startComputation=(Button) findViewById(R.id.button2);
displayText=(TextView) findViewById(R.id.textView1);
startComputation.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
String numberOfGates=inputData.getText().toString();
ArrayList send=new ArrayList();
send.add(numberOfGates);
dataTransfer=new DataTransfer();
dataTransfer.execute(send);
}
});
sendParameters.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dataReceiving=new DataReceiving();
dataReceiving.execute();
}
});
}
public class DataReceiving extends AsyncTask<Void, Void, ArrayList>
{
#Override
protected ArrayList doInBackground(Void... params) {
ArrayList receivedData=new ArrayList();
Log.i("DataReceiving", "doInbackgroung works");
try {
receivedData=receive();
} catch (ClassNotFoundException e) {
Log.e("DataReceiving", "Problems with receive method. Issue with class");
e.printStackTrace();
} catch (IOException e) {
Log.e("DataReceiving", "Problems with receive method. Issue with IO");
e.printStackTrace();
}
return receivedData;
}
#Override
protected void onPostExecute(ArrayList result) {
super.onPostExecute(result);
displayText.setText(result.toString());
}
}
public ArrayList receive () throws IOException, ClassNotFoundException
{
Log.i("receive method", "works");
ServerSocket s= new ServerSocket(8888);
Log.i("receive method", "ServerSocket(8888)");
Socket incoming =s.accept();
Log.i("receive method", "accept()");
ObjectInputStream ios = new ObjectInputStream(incoming.getInputStream());
Log.i("receive method", "ios");
ArrayList b=new ArrayList();
b = (ArrayList) ios.readObject();
Log.i("receive method", "data were received");
ios.close();
incoming.close();
s.close();
return b;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
Here is the Log

It seems like Socket incoming =s.accept(); doesn't work and I have no idea why

Server side is very simple
Socket s=new Socket("192.168.1.110", 8888);
ObjectOutputStream oos=new ObjectOutputStream(s.getOutputStream());
ArrayLIst b = new ArrayList();
b.add("It Works");
oos.writeObject(b);
oos.close();
s.close();
I will be very appreciated for any Ideas, how to fix this problem. Thank you
I think the client part is working right, it stops at the accept method. So the problem is in the server which never gets to connect.
The server part should be like this:
try {
Socket s = new Socket();
InetAddress addr = InetAddress.getByName("192.168.1.110");
SocketAddress sockaddr = new InetSocketAddress(addr, 8888);
s.connect(sockaddr, 20000); // 20 seconds time out
ObjectOutputStream oos=new ObjectOutputStream(s.getOutputStream());
ArrayLIst b = new ArrayList();
b.add("It Works");
oos.writeObject(b);
oos.close();
s.close();
}
catch (Exception e)
{
.....
}
Part of my application creates some files in the external storage and writes into them.
Everything was working like a charm until I changed something, I don't remember what. Now application creates files but doesn't write anything, i.e the files are empty.
Any ideas what is the problem?
Here is my manifest file
<?xml version="1.0" encoding="utf-8"?>

Here is where I write to a file. I haven't changed anything though. It was like this when it was working
public class GraphHelper {
File directory;
File myExternalFile;
PrintWriter writer;
FileOutputStream outputStream;
ArrayList<float[]> dataList;
float []toWrite;
String strToWrite;
private String filepath = "MyFileStorage";
public GraphHelper(Context context)
{
directory = context.getExternalFilesDir(filepath);
}
public GraphHelper(Application application)
{
directory = application.getExternalFilesDir(filepath);
}
public void writeToFile(String filename,ArrayList <float[]>data)
{
if(isExternalStorageAvailable()&&!isExternalStorageReadOnly())
{
myExternalFile = new File(directory, filename);
try {
outputStream = new FileOutputStream(myExternalFile);
writer = new PrintWriter(outputStream);
dataList = data;
for(int i=0;i< data.size();i++)
{
toWrite = data.get(i);
System.out.println("toWrite[1]: "+toWrite[0]+"toWrite[2]: "+toWrite[1]);
}
writer.close();
outputStream.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}}
}
private static boolean isExternalStorageReadOnly() {
String extStorageState = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(extStorageState)) {
return true;
}
return false;
}
private static boolean isExternalStorageAvailable() {
String extStorageState = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(extStorageState)) {
return true;
}
return false;
}
you never call print
for(int i=0;i< data.size();i++) {
toWrite = data.get(i);
System.out.println("toWrite[1]: "+toWrite[0]+"toWrite[2]: "+toWrite[1]);
writer.print(toWrite);
}
writer.flush();
writer.close();
I am sure this is simple but I cannot figure it out. All I am trying to do is send a message via NFC. The code I have work perfectly if I am sending it to the main activity, but I don't know how to send it to a different activity. I have looked over both the NFC and Intent Filter articles on the Android Developer pages but am still not sure exactly how to do this. I am trying to send it to a NFC activity, I will post my manifest and NFC class below.

In my android app i am using Latest Geoloqi API to implement Geofence concept.when user entered into some region he has notify, for that purpose i am using Push Notifications.in GeoReceiver class three callback methods are calling but not onPushMessageReceived().please help me how to do it?
I am creating trigger with current location is it required to enter into region manually or since i am already in the location its not calling?
Note:I ve given required credentials in assets/geoloqi.properties file.when app is launched in logcat "Successfully registered for the C2DM service" msg also displayed.my code:
GeoloqiExampleActivity.java
public class GeoloqiExampleActivity extends Activity{
String TAG = "Geoloqi Example";
private LQService mService;
private boolean mBound;
GeoReceiver geoReceiver = new GeoReceiver();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = new Intent(this, LQService.class);
startService(intent);
}
#Override
public void onResume() {
super.onResume();
// Bind to the tracking service so we can call public methods on it
Intent intent = new Intent(this, LQService.class);
bindService(intent, mConnection, 0);
// Wire up the sample location receiver
final IntentFilter filter = new IntentFilter();
