The problem is i am able to sending the data to the ubidots however i want to make it so that only if the condition has met, it will then send to the cloud. Other than that, it would not have send any data to the cloud.

Getting problems when using MVP model to write a "login" App

I tried to write a "login" App using MVP model. And I use WAMP to build up my server. I'm sure that my php documents have no problem.
Here is the structure of my App:

But I got something wrong like this:
enter image description here
I have no idea about it. How to solve it?

the issue is here
this.userBiz = new UserBiz();
UserBiz is an activity so activity gets their context when they are being started with Intent (by OS) but creating an object of an activity will not provide any contenxt hence the null exception at
#Override
public void login(final String username, final String password, final OnLoginListener mLoginListener)
{
user = new User();
user.setUsername(username);
user.setPassword(password);
user.setStatus(0);
loginListener = mLoginListener;
LoginAsyncTask task = new LoginAsyncTask();
String test1Url = getString(R.string.server_ip)+"/server/login.php";
// no context here due to new UserBiz
// getString required context
task.execute(test1Url);
}
Solution : you can use enums or static final constants to avoid context and also would be wise to substitute UserBiz as separate class instead of an activity

ACRA 4.9.0 : How can I write ACRA report to file (in Application data folder)

Because i was using jar file instead of aar
in my manifest i was missing
<service

enter code here
That,s why SendeService used in Acra was not starting.

I want to write the crash report in text file using latest Acra 4.9.0. I can,t example for this latest version.
If you want to write to a .txt file on server, try this backend. Uses the default sender:
<?php
// Outputs all POST parameters to a text file. The file name is the date_time of the report reception
$fileName = date('Y-m-d_H-i-s').'.txt';
$file = fopen($fileName,'w') or die('Could not create report file: ' . $fileName);
foreach($_POST as $key => $value) {
$reportLine = $key." = ".$value."\n";
fwrite($file, $reportLine) or die ('Could not write to report file ' . $reportLine);
}
fclose($file);
?>
If you only want to write locally, then the point of ACRA disappears as you cannot get the files.
If you create .txt files to transmit them, it is actually better to use the backend I linked. It transmits the raw data, and you can get all your fields in a .txt file

Can't create handler inside thread that has not called Looper.prepare()

EDIT: My solution was to have a constant class with this code:
static EditText Port = (EditText) MainActivity.mDialog.findViewById(R.id.txtPort); static int mPort = Integer.parseInt(Port.getText().toString()); public static final int PORT = mPort;
I've tried to see the other questions and I understand that I've gotta do something with the UIThread? Honestly, I understand nothing. Im new with android.
The app (chat app) worked fine until I wanted to have multiple ports options depending if I'm hosting (port 5050) or joining (port 80) a chat room. From the beginning i just had a constant value of the port (public static final int PORT) but now i cant have that ofc. If you guys have any other suggestions on how i can have two values of PORT, please share your tips.
Anyway, after trying EVERYTHING I decided to put a method in my main class, and just declare it in other classes. This is the mothod for the value of the port:
public int getPORT() {
txtPORT = (EditText) findViewById(R.id.txtPort);
//String txtPORTa = txtPORT.getText().toString();
int dennaPORT = 0;
if (mJoin.isChecked()) {
dennaPORT = Integer.parseInt(txtPORT.getText().toString());
return dennaPORT;
}
else if (mHost.isChecked()) {
dennaPORT = 5050;
return dennaPORT;
}
return dennaPORT;
}

NEVER create an instance of an Activity, Service, or ContentProvider yourself. Those are always created by the framework. Delete:
MainActivity porten = new MainActivity();
Pass the port into the strangely-named Server class by some other means, such as a constructor parameter or setter method.

Starting new activity through Runnable

I check if a string is NULL in a Thread, if its null, the Handler starts
a Runnable which starts a new Activity.
Everything works fine, but, after the new activity is displayed it switches back to the calling Activity and it crashes.
Here is a code snippet.
if(username==null)
{
dialogs.dismiss();
handlers.post(new MyRunable());
}
and Runnable is
public class MyRunable implements Runnable
{
public void run(){
Toast.makeText(ListActivity.this, "Your Connection is too slow",Toast.LENGTH_LONG).show();
startActivity(new Intent(ListActivity.this,Anim.class));
}
}

use main thread to start your thread check runOnUiThread(Runnable action)

Setting RETURN in the try catch block and setting
android:noHistory="true" in Android Manifest for all activities fixed my problem

If you are trying to create an async task in a different thread I would recommend you to use the following class:
private final class MyRunnable extends
AsyncTask<Void, Void, Document> {
protected Document doInBackground(Void... params) {
}
protected void onPostExecute(Document result) {
}
}
You only have to change the parameters.

Finish your current activity when starting another activity from runnable .
