writting class object in a file in extarnal storage

writting class object in a file in extarnal storage - android

at first, i am using Nexus 7 as my testing device.
i want to save a class object with its all variables current value in a file and want to save the file in such place so that, after reboot of the phone (assuming that the phone is shutted down by the user) , i can get the object from the file and can use the data (which are saved in the variables in the saved object class) for my further use. where should i save my file (with the object) such that, it will work for most of the devices.
here is my code(writting a class object in a file in extarnal storage):
File file = new File(Environment.getExternalStorageDirectory(), "savedData");
if(!file.exists()){
file.createNewFile();
Toast.makeText(getActivity(), "not exist", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getActivity(), "exist", Toast.LENGTH_LONG).show();
}
if(file.canWrite())
Toast.makeText(getActivity(), "writable", Toast.LENGTH_LONG).show();
else
Toast.makeText(getActivity(), "not writable", Toast.LENGTH_LONG).show();
FileOutputStream fos = new FileOutputStream(file);
String car = "ferrari";
ObjectOutputStream os = new ObjectOutputStream(fos);
os.writeObject(app);
os.writeObject(car);
os.close();
here is my code(reading the class object from the file from extarnal storage):
File file = new File(Environment.getExternalStorageDirectory(), "savedData");
FileInputStream fis = new FileInputStream(file);
ObjectInputStream is = new ObjectInputStream(fis);
savedData = (SavedFriend) is.readObject();
String car = (String) is.readObject();
Toast.makeText(getApplicationContext(), car, Toast.LENGTH_LONG).show();
is.close();
i have written object in one class and read it from another class. as you can see, i have written a string (car) as object for test purpose and the class object. i have read them in another class. now the value of class object and string (car) are showing perfectly. that means they are written well in the file in external storage. but when i shut down my Nexux 7 (for testing the app) and run the app again, the value of string (car) is showing perfectly, but the values of the variables from the class object are showing null. what is the problem?
in my manifest i have added:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
by the way, the class's object i want to write as object implements Serializable .... even, i have implements Serializable for all classes for test . but it is not working.
i cannot use Database or other storage technique, because i have came a long way with this app so if i use other technique, i have to change most of my code. please help.
is it possible to write the object in phone's internal memeory? i have also write the file using getActivity().getApplicationContext().openFileOut() before. but i fetch the same problem with that approach.

It is referenced in the android documentation here: https://developer.android.com/guide/topics/providers/content-provider-creating.html#MIMETypes
Note that these MIME types are supported only if the user has the appropriate app for it. I don't think that you can display the supported MIME types programmatically. However you can check if the one that you want to use is supported using code like this :
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(someUri, "YOUR_MIME_TYPE_HERE");
if(intent.resolveActivity(activity.getPackageManager()) != null)
{
lActivity.startActivity(intent);
}
else
{
Log.w(TAG, "There is no application for this MIME type");

I want to change the color of the text depending on the value from php jsonobject. The program can already get the value and able to display it on each textview. But my problem is, how can I change the color of each text view at the same time, depending on the Flimitstat, Vlimitstat and Climitstat. Hope you can help me!

You can check my listadapter and i have implemented the same concept to set the text color in two ways
private class CustomerAdapter extends ArrayAdapter<RouteTrackerUser>
{
Context context;
int textViewResourceId;
private ArrayList<RouteTrackerUser> originalitems;
public CustomerAdapter(Context context, int textViewResourceId, ArrayList<RouteTrackerUser> items) {
super(context, textViewResourceId, items);
this.textViewResourceId = textViewResourceId;
this.context = context;
this.originalitems = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
v = inflater.inflate(textViewResourceId, parent, false);
}
final RouteTrackerUser r = originalitems.get(position);
if (r != null) {
TextView textName= (TextView) v.findViewById(R.id.sname);
TextView postal=(TextView) v.findViewById(R.id.postal);
if(r.getVisited().equals("true"))
{
if(textName != null)
{
textName.setTextColor(getResources().getColor(R.color.lightpurple));
textName.setText(r.getStorename());
}
if(postal != null)
{
postal.setTextColor(getResources().getColor(R.color.lightpurple));
postal.setText("Address: "+r.getPostalcode());
}
}
if(r.getVisited().equals("false"))
{
if(textName != null)
{
textName.setTextColor(getResources().getColor(R.color.darkpurple));
textName.setText(r.getStorename());
}
if(postal != null)
{
postal.setTextColor(getResources().getColor(R.color.darkpurple));
postal.setText("Address: "+r.getPostalcode());
}
}
if(RouteTrackerApp.sharedPreference.getInt(RouteTrackerApp.SHARED_ACCESS_UTYPE, 0) == Constants.VAR_TYPE_SALES_PERSON){
v.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
viewdata(r.getUsername(),r.getStoreid(),r.getAccountid(),r.getUid(),r.getVisitplanid(),r.getVisited(),r.getStorename());
}});
}
}
return v;
}
}
and on PostExecute i called this adapter like
protected void onPostExecute(ArrayList<RouteTrackerUser> result)
{
if(result!=null)
{
// System.out.println("User with result===>"+result);
/*for(RouteTrackerUser r :result ){
System.out.println("StoreName===>"+r.getStorename());}*/
Intent intent=getIntent();
TextView username=(TextView)findViewById(R.id.usrname);
final String sname=intent.getExtras().getString("user_name");
username.setText("Welcome, "+sname);
TextView todayvisits=(TextView)findViewById(R.id.todaylist);
todayvisits.setText("TODAY'S STORE VISITS");
userAdapter = new CustomerAdapter(ViewYourPlanList.this, R.layout.view_your_plan_list,result);
userList = (ListView) findViewById(R.id.listview);
userList.setItemsCanFocus(false);
userList.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
userList.setAdapter(userAdapter);
dialog.dismiss();
}
else
if you are want to implement in listfragment ! Design a customadapter and set the text color like i shown below and call this customadapter on postexecute.
public class CustomAdapter extends ArrayAdapter<Model> {
private final LayoutInflater mInflater;
public CustomAdapter(Context context) {
super(context, android.R.layout.simple_list_item_2);
mInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void setData(List<Model> data) {
clear();
if (data != null) {
for (Model appEntry : data) {
System.out.println("cust adptr set data: "+appEntry.getStorename());
add(appEntry);
}
}
}
/**
* Populate new items in the list.
*/
#SuppressLint("SimpleDateFormat")
#Override public View getView(int position, View convertView, ViewGroup parent) {
View view;
if (convertView == null) {
view = mInflater.inflate(R.layout.view_your_plan_weekly, parent, false);
} else {
view = convertView;
}
Model item = getItem(position);
int dayVal = Calendar.getInstance().get(Calendar.DAY_OF_WEEK)-1;
ImageView arrow=(ImageView)view.findViewById(R.id.arrow_image);
arrow.setVisibility(View.INVISIBLE);
if(item.getTabId().equals(String.valueOf(dayVal))){
arrow.setVisibility(View.VISIBLE);
}
if(item.getVisited().equals("true"))
{
((TextView)view.findViewById(R.id.sname)).setText(item.getStorename());
((TextView)view.findViewById(R.id.postal)).setText(item.getPostal());
((TextView)view.findViewById(R.id.sname)).setTextColor(Color.parseColor("#D397D4"));
((TextView)view.findViewById(R.id.postal)).setTextColor(Color.parseColor("#D397D4"));
}
if(item.getVisited().equals("false"))
{
((TextView)view.findViewById(R.id.sname)).setText(item.getStorename());
((TextView)view.findViewById(R.id.postal)).setText(item.getPostal());
((TextView)view.findViewById(R.id.sname)).setTextColor(Color.parseColor("#9B419B"));

setListAdapter(adapter);
and instead of SimpleAdapter you use customadapter. In CustomAdapter you can set the textcolor as i shown in my previous post.Just go through the class "public class CustomAdapter extends ArrayAdapter "

This code is too slow - that reads 3-4 contacts per second on average. Is this normal or can be optimized?
I think projection might be a good candidate to be optimized but I'm not sure.
Thanks in advance.

It's hard for me to tell exactly what you're trying to do, but it looks like you're trying to read data from the Contacts Provider and send it to a server using JSON. I suggest you look at the ContactsContract.RawContacts.Entity table, which contains all the data you're probably looking for without the mess of trying to figure out the MIME type of the DATA row you've just retrieved. You're certainly slowing down your app by getting the entire contents of the DATA row.
In addition, you should use a SyncAdapter to do this work. See Transferring Data Using Sync Adapters

Reading contacts can be made in 2-5 seconds. See the example app here

Bluetooth not sending file to other device

It is already asked but i didn't find any solution. For bluetooth application i am using the bluetoothShare.class .
My source code for sending the file to the target device
MainActvity.class:
Set<BluetoothDevice> devices = btAdapter
.getBondedDevices();
final String btDeviceName = selected_deviceName;
BluetoothDevice device = null;
for (BluetoothDevice itDevice : devices) {
if (btDeviceName.equals(itDevice.getName())) {
device = itDevice;
}
}
if (device != null) {
ContentValues values = new ContentValues();
values.put(BluetoothShare.URI, uri.toString());
values.put(BluetoothShare.MIMETYPE, "image/jpeg");
values.put(BluetoothShare.DESTINATION,
device.getAddress());
values.put(BluetoothShare.DIRECTION,
BluetoothShare.DIRECTION_OUTBOUND);
Long ts = System.currentTimeMillis();
values.put(BluetoothShare.TIMESTAMP, ts);
final Uri contentUri = getApplicationContext()
.getContentResolver().insert(
BluetoothShare.CONTENT_URI, values);
Log.v(TAG, "Insert contentUri: " + contentUri
+ " to device: " + device.getName());
Toast.makeText(getApplicationContext(), "Success",
Toast.LENGTH_LONG).show();
} else {
textStatus
.setText("Bluetooth remote device not found");
}
} else {
textStatus.setText("Bluetooth not activated");
}
}
else {
Toast.makeText(getApplicationContext(), "No devices found",
Toast.LENGTH_LONG).show();
}

BluetoothShare class not supported android 4.1 and above. you can use the following intent coding to send file in android version 4.1 and above
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setComponent(new ComponentName(
"com.android.bluetooth",
"com.android.bluetooth.opp.BluetoothOppLauncherActivity"));
intent.setType("image/jpeg");
file = new File(filepath);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
startActivity(intent);
and also some devices in Android v 2.2/2.3 not send the file via bluetoothShare class.

Maybe you can try another solution with BufferedWriter and BufferedReader.
Here is a snipped code:
BluetoothDevice mmDevice;
Set<BluetoothDevice> mBluetoothAdapter;
BluetoothAdapter bAdapter = BluetoothAdapter
.getDefaultAdapter();
mBluetoothAdapter = bAdapter.getBondedDevices();
for (BluetoothDevice bc : mBluetoothAdapter) {
if (bc.getName().indexOf("name_of_bluetoothdevide") != -1) {
UUID uuid = UUID
.fromString("00001101-0000-1000-8000-00805F9B34FB"); // Standard
// SerialPortService
// ID
mmDevice = bc;
BluetoothSocket mmSocket = mmDevice
.createInsecureRfcommSocketToServiceRecord(uuid);
bAdapter.cancelDiscovery();
mmSocket.connect();
BufferedWriter Writer = new BufferedWriter(
new OutputStreamWriter(
mmSocket.getOutputStream()));
Writer.write("Bluetooth connected!");
Writer.flush();
app.setmSocket(mmSocket);
break;
}
}
And for reading:
BufferedReader Reader = new BufferedReader(
new InputStreamReader(mmSocket.getInputStream()));
receivedMsg = Reader.readLine();
Hope it can help you.

This code works with firmware from MediaTek. Tested on Android 4.0.4. Sends the file, without asking anything from the user
public boolean SendFileViaBluetoothOPP(String file_path, String destinationMAC){
BluetoothAdapter btadapter = BluetoothAdapter.getDefaultAdapter();
if(btadapter == null)
return false;
BluetoothDevice btdev = btadapter.getRemoteDevice(destinationMAC);
if(btdev == null)
return false;
Uri uri = Uri.fromFile(new File(file_path));
Intent shareIntent = new Intent(Intent.ACTION_SEND)
.putExtra(Intent.EXTRA_STREAM, uri)
.setType("application/zip");
List<ResolveInfo> resolvedActivities = getPackageManager().queryIntentActivities(shareIntent, 0);
boolean found = false;
for(ResolveInfo actInfo: resolvedActivities){
if(actInfo.activityInfo.packageName.equals("com.mediatek.bluetooth"))
{
shareIntent.setComponent( new ComponentName(actInfo.activityInfo.packageName, actInfo.activityInfo.name ) );
shareIntent.putExtra("com.mediatek.bluetooth.sharegateway.extra.DEVICE_ADDRESS", btdev);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
found = true;
break;
}
}
if(found){
startActivity(shareIntent);
return true;
}
return false;
}
On older phone from MediaTek with Android 2.2.1 this code launches BluetoothDevicePicker to complete the operation.

Maybe this could help you in some way…
private void sendData(String message) {
byte[] msgBuffer = message.getBytes();
Log.d(TAG, "...Sending data: " + message + "...");
try {
outStream.write(msgBuffer);
} catch (IOException e) {
String msg = "In onResume() and an exception occurred during write: " + e.getMessage();
if (address.equals("00:00:00:00:00:00"))
msg = msg + ".\n\nUpdate your server address from 00:00:00:00:00:00 to the correct address on java code";
msg = msg + ".\n\nCheck that the SPP UUID: " + MY_UUID.toString() + " exists on server.\n\n";
errorExit("Fatal Error", msg);
}
}
