JVMTI_ERROR_THREAD_NOT_ALIVE error using multiple activites and OpenWeatherMap API

I am making an weather app, on the main screen app shows current weather for a city that is chosen and on the second activity screen you can find weather for next 3 days. I have WeatherInfoTask.java that is used to get JSON for MainActivity and MultipleWeatherTask.java that is used to get JSON for MultipleDays (activity)
so the MainActivity works fine and I get JSON and all of the info is shown on the screen just as it should be, but when I click on the button that should redirect me to the screen of the MultipleDays, I am redirected and just a plain screen is shown without data and this error is shown:
E/StudioProfiler: JVMTI error: 15(JVMTI_ERROR_THREAD_NOT_ALIVE)

Handle stream of data sensor

I'm trying to write a code I can write all the results values from accelerometer sensor into a .txt file. I can't write all the data in somehow. I think there is a problem in my loop. It is just reading about 10 to 15 samples.
How can I write all the values of the sensor into that file until I toggle off the button to stop? here is the code I wrote.

Could you try this for the toggle button onClick callback? It should write all the data when it's unchecked.
OnStore.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
if (OnStore.isChecked()){
// should do nothing
} else if (!OnStore.isChecked()){
try {
for(double TotalAccelerate : list){
//System.out.println("final"+ TotalAccelerate);
String space = "\n";
byte[] convert = space.getBytes();
fileOutputStream.write(convert);
String finalData;
finalData = String.valueOf(TotalAccelerate);
fileOutputStream.write(finalData.getBytes());
Log.i(DEBUG, "ans: " + finalData);
}
fileOutputStream.flush();
fileOutputStream.close();
Toast.makeText(getApplicationContext(), "Message saving", Toast.LENGTH_LONG).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Toast.makeText(getApplicationContext(),"Message Stopped.",Toast.LENGTH_LONG).show();
}
}
});
To regulate the code to start/stop listen to the sensor event, add the following variable somewhere in this class:
private boolean isListening = false;
And make the following modifications to your existing code:
OnStore.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
if (OnStore.isChecked()){
//
// set listening flag to true
//
isListening = true;
} else if (!OnStore.isChecked()){
//
// set listening flag to false
//
isListening = false;
try {
for(double TotalAccelerate : list){
//System.out.println("final"+ TotalAccelerate);
String space = "\n";
byte[] convert = space.getBytes();
fileOutputStream.write(convert);
String finalData;
finalData = String.valueOf(TotalAccelerate);
fileOutputStream.write(finalData.getBytes());
Log.i(DEBUG, "ans: " + finalData);
}
fileOutputStream.flush();
fileOutputStream.close();
Toast.makeText(getApplicationContext(), "Message saving", Toast.LENGTH_LONG).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Toast.makeText(getApplicationContext(),"Message Stopped.",Toast.LENGTH_LONG).show();
}
}
});
#Override
public final void onSensorChanged(SensorEvent event) {
// The light sensor returns a single value.
// Many sensors return 3 values, one for each axis.
//
// regulate
//
if (isListening) {
double xx = event.values[0];
double yy = event.values[1];
double zz = event.values[2];
TotalAccelerate = Math.round(Math.sqrt(Math.pow(xx, 2)
+ Math.pow(yy, 2)
+ Math.pow(zz, 2)));
Log.i(DEBUG, "Accelerometer = " + TotalAccelerate);
list.add(TotalAccelerate);

FileNotFoundException when upload multiple images to FTP server

After selecting multiple images from a gallery, I want to upload them to an ftp server. During the upload, I get the following error:
"java.io.FileNotFoundException: /storage/emulated/0/DCIM/Camera/IMG_20150724_220209.jpg /storage/emulated/0/DCIM/Screenshots/Screenshot_2015-08-04-14-47-38.png "
Can anyone help?

OCR with text to speech

I'm in trouble with this android java class.
The goal that I'm trying to reach with this activity is:
start camera-->take photo-->recognize text-->(tts and recognized text in the edittext)
TTS would had to start automatically after the text recognition. But it didn't. The recognized text also must appear in the edit text (and it's work)
I'm ok with the three first steps. TTS gives me an issue: "speak failed: not bound to TTS engine". I'm trying to understand where is the problem. I also followed some guide to use tts, I think the problem is about stop or shutdown of tts. Any idea? Thanks a lot
