Attempt to invoke virtual method 'java.io.InputStream android.bluetooth.BluetoothSocket.getInputStream()'

I am trying to connect my android app with hc-06 for sending and receiving data purpose, below is the error occur and I've been stuck here from 3 days.
There error occured to me is

Getting the value from textview

Hello guys I got a code that I do for my project, the code is to get the value of the heartbeat sensor from Arduino to my android phone using Bluetooth. So far it's going well it can send the value to my app without a problem. but the problem now is I want to get the value of it so I can use my algorithm with it, but seems like I got in a pickle now.

What i want is to get the value of mTxtReceive on this :
int txtLength = mTxtReceive.getEditableText().length();
if(txtLength > mMaxChars){
mTxtReceive.getEditableText().delete(0, txtLength - mMaxChars);
System.out.println(mTxtReceive.getText().toString());
}
I used System.out.println for seeing if i got the value but in the log it didn't show any thing.
So i need you guys wisdom for this any help?

Your view mTextReceive seems to be a TextView and therefore not editable:
private TextView mTxtReceive;
If it's not an EditText (editable) mTxtReceive.getEditableText will return null see docs
and getText should be called instead see docs.
Therefore your condition might always resolve from
if(txtLength > mMaxChars) into if(null > 50000) which is always false (or actually it might even crash before) and therefore your code inside the if-block is never executed
Try:
// recommended for debugging. Check if this is even called and if text length is really longer than max chars
Log.d(TAG, "text length:" + mTxtReceive.getText().length());
int txtLength = mTxtReceive.getText().length();
if(txtLength > mMaxChars){
// not sure what operation you want to do here but leave out for debugging
Log.d(TAG, "text longer than allowed:" + mTxtReceive.getText().toString());
}
Also use Log.d instead of System.out.println since your log might otherwise not be forwarded to Logcat. Also are you sure this block is executed at all? I'd put a Log.d(TAG, "text length:" + mTxtReceive.getText().length()); outside of the condition for debugging purposes. And finally the obvious question would be if the txtLength is even longer than max chars (and that would be quite a long text with 50000 chars). But you can verify that simply with the recommended log outside the block as well.

Use Common MQTT class for Android APP

I am an novice android developer, I am using MQTT protocol for my android app.
I have found a code from internet for MQTT.But problem is that i have to use this MQTT Code for every activity which is redundant.I want to make a common java class
which can be call called any time whenever i need MQTT connection and communication.I have already tried but failed.Please anyone suggest me how to approach this?The code is given below
com.example.ab.mushroomv2;
import org.eclipse.paho.android.service.MqttAndroidClient;
import org.eclipse.paho.client.mqttv3.IMqttActionListener;
import org.eclipse.paho.client.mqttv3.IMqttDeliveryToken;
import org.eclipse.paho.client.mqttv3.IMqttToken;
import org.eclipse.paho.client.mqttv3.MqttCallback;
import org.eclipse.paho.client.mqttv3.MqttClient;
import org.eclipse.paho.client.mqttv3.MqttException;
import org.eclipse.paho.client.mqttv3.MqttMessage;
public class DashboardActivity extends AppCompatActivity {
final Context context = this;
//private EditText result;
private static final String TAG = "DA";
ProgressBar p_temp;
TextView progressingTemp;
MqttAndroidClient client;
String clientId;
static String topicTemp = "mushroom/temp";
String subMsg, top;
static String host = "tcp://iot.eclipse.org:1883";
Handler progressHandler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard);
p_temp = (ProgressBar) findViewById(R.id.progress_bar_temp);
progressingTemp = (TextViewfindViewById(R.id.progress_circle_temp_text);
establish();
client.setCallback(new MqttCallback() {
#Override
public void connectionLost(Throwable cause) {
establish();
}
#Override
public void messageArrived(String topic, MqttMessage message) throws
Exception {
subMsg = new String(message.getPayload());
top=new String(topic);
if(top.contains("temp"))
{
double a=Double.parseDouble(subMsg);
final int msgTemp = (int) a;
Log.d(TAG, String.valueOf(msgTemp));
new Thread(new Runnable() {
public void run() {
progressHandler.post(new Runnable() {
public void run() {
p_temp.setProgress(msgTemp);
progressingTemp.setText("" + msgTemp + " ℃
");
}
});
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
}
}
#Override
public void deliveryComplete(IMqttDeliveryToken token) {
}
});
}
public void establish() {
clientId = MqttClient.generateClientId();
client = new MqttAndroidClient(this.getApplicationContext(), host,
clientId);
try {
IMqttToken token = client.connect();
token.setActionCallback(new IMqttActionListener() {
#Override
public void onSuccess(IMqttToken asyncActionToken) {
// We are connected
Toast.makeText(DashboardActivity.this, "Client Connected",
Toast.LENGTH_SHORT).show();
try {
client.subscribe(topicTemp, 0);
} catch (MqttException e) {
e.printStackTrace();
}
}
#Override
public void onFailure(IMqttToken asyncActionToken, Throwable
exception) {
Toast.makeText(DashboardActivity.this, "Client failed to
Connect", Toast.LENGTH_SHORT).show();
// establish();
}
});
} catch (MqttException e) {
e.printStackTrace();
}
}
}

You need to create a singleton class. Here is an sample.
public class SocketIO {
private static final String TAG = SocketIO.class.getSimpleName();
private static SocketIO instance;
private Socket socket;
private SocketIO() {
try {
socket = IO.socket("http://ur_url_here");
} catch (URISyntaxException e) {
e.printStackTrace();
Log.e(TAG, e.getMessage());
}
}
public static synchronized SocketIO getInstance() {
if (instance == null) {
instance = new SocketIO();
}
return instance;
}
public Socket getSocket() {
return socket;
}
public void open() {
if (socket != null)
socket.open();
}
public void close() {
if (socket != null)
socket.close();
}}

How to change layout background dynamically

I am having problem in my code.I am trying to change the layout background of my app every second.I used Thread in this code.I've searched the site but I couldn't find anything useful.Here is the code.
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.LinearLayout;
public class MainActivity extends Activity {
//private Bitmap open, close;
private LinearLayout myL;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myL = (LinearLayout) findViewById(R.id.LinearLayout2);
// myL=(LinearLayout) findViewById(R.id.LinearLayout2);
//close = BitmapFactory.decodeResource(getResources(), R.drawable.kapa);
//open = BitmapFactory.decodeResource(getResources(), R.drawable.ac);
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
Thread th = new Thread() {
public void run() {
while (true) {
myL.setBackgroundResource(R.drawable.kapa);
try {
sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
myL.setBackgroundResource(R.drawable.ac);
try {
sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
};
th.start();
}
}

From the answer to this question Change Layout background continuously...
Try using a Handler. Example...
public class MainActivity extends Activity {
final int CHANGE_BG_RES = 1;
final int RESOURCE_1 = R.drawable.kapa;
final int RESOURCE_2 = R.drawable.ac;
private LinearLayout myL;
private Handler handler = new Handler() {
public void handleMessage(Message msg) {
if (CHANGE_BG_RES == msg.what) {
int res = msg.arg1;
myL.setBackgroundResource(res);
int nextRes;
if (RESOURCE_1 == res)
nextRes = RESOURCE_2;
else
nextRes = RESOURCE_1;
Message m = obtainMessage (CHANGE_BG_RES, nextRes, 0, null);
sendMessageDelayed(m, 1000);
}
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myL = (LinearLayout) findViewById(R.id.LinearLayout2);
}
#Override
protected void onResume() {
super.onResume();
Message m = handler.obtainMessage(CHANGE_BG_RES, RESOURCE_1, 0, null);
handler.sendMessageDelayed(m, 1000);
}
}

Try this:
public class MainActivity extends Activity {
//private Bitmap open, close;
private LinearLayout myL;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myL = (LinearLayout) findViewById(R.id.LinearLayout2);
// myL=(LinearLayout) findViewById(R.id.LinearLayout2);
//close = BitmapFactory.decodeResource(getResources(), R.drawable.kapa);
//open = BitmapFactory.decodeResource(getResources(), R.drawable.ac);
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
Runnable runnable = new Runnable() {
#Override
public void run() {
while(true) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
myL.setBackgroundResource(R.drawable.kapa);
}
});
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
myL.setBackgroundResource(R.drawable.ac);
}
});
}
}
};
new Thread(runnable).start();
}
}

Display success message after file is copied

I am fairly new to Android development so I thought I would start off with a basic app. When a button is pressed, it copies a file to the location written in the code (see my code below). When I press the install button and the file is copied to its location, I want a toast message to display "Successfully Installed or Error while copying file". How would I implement this?
public class TrialActivity extends Activity {
private ProgressDialog progressDialog;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
runDialog(5);
}
private void runDialog(final int seconds)
{
progressDialog = ProgressDialog.show(this, "Please Wait...", "unpacking patch in progress");
new Thread(new Runnable(){
public void run(){
try {
Thread.sleep(seconds * 1000);
progressDialog.dismiss();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
((Button)findViewById(R.id.button1)).setOnClickListener(new View.OnClickListener()
{
public void onClick(View paramView)
{
}
{
InputStream in = null;
OutputStream out = null;
String filename="savegame.bin";
try {
in = getResources().openRawResource(R.raw.savegame);
out = new FileOutputStream("/sdcard/Android/data/files/" + filename);
copyFile(in, out);
in.close();
in = null;
out.flush();
out.close();
out = null;
} catch(Exception e) {
Log.e("tag", e.getMessage());
}
}
private void copyFile(InputStream in, OutputStream out) throws IOException {
byte[] buffer = new byte[1024];
int read;
while((read = in.read(buffer)) != -1){
out.write(buffer, 0, read);
}
}
}
);
}
}

use next code:
private class AsyncTaskDialog extends AsyncTask<Void, Void, Void> {
Toast toastSuccess;
boolean flagSuccessCopy =false;
protected void onPreExecute() {
super.onPreExecute();
}
}
protected Boolean doInBackground(Void... params) {
copyFiles();
return null;
}
#Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
if (getActivity() != null) {
if(flagSuccessCopy){
toastSuccess = Toast.makeText(context, "Success", duration);
}else{
toastSuccess = Toast.makeText(context, "Error", duration);
}
toast.show();
}
}
