Trying to tweak the app by launching the DetectorActivity(main activity that does the detection) only when a button is clicked.
So within the source code, I've added a class "Main Activity", set it as the launching activity in the manifest, and in it's xml, added a button that when clicked, should send an intent to the DetectorActivity and launch it. The code is pretty much this :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void on(View v){
Intent i = new Intent(this,DetectorActivity.class);
startActivity(i);
}
However, the activity is never launched, which is quite baffling.
Here is the logcat of the emulator:

How are you setting the click listener? This log suggests it's not being called.
The comment by #RyanMentley solved it, thanks a bunch.

The application is very laggy and the more things are being clicked, the more it lags. At some point it completely freezes. This is my error log. How can i optimize it? (Full beginner)

I am running a downloaded tested code from an Android app development course by Rob Percival in Android studio.
The code is for fetching HTML content of a specified URL and displaying it in the logs.
It's the tested code provided by the author of the course.
The code runs fine but only a part of the HTML content of the specified URL is displayed in the logs.
These are the additional log entries I'm getting:

My app always shutdown in random time interval (mostly from few minutes to something like 20 mins). The "App stopped working" messagebox appears. Biggest problem is, I don't do anything in app (like interacting with it), and it just random shutdown by itself. Here's logcat print:

One would say, it's because I didn't write setMeasuredDimension() when overriding method onMeasure(). Also, docs say you have to write this line to your onMeasure, otherwise the IllegalStateException will be thrown (see it here).
But I don't overriding onMeasure anywhere in my whole project, so problem is not here (at least not on my side in this case).
Few things to note:
this is full logcat log, and any of these lines ("at android. ...") doesn't link to my code, all goes to source - that means all of these links are gray
this exception always happens only on my S3 Mini (android 4.1.2), but never happened on my old Galaxy Ace S5830i (android 2.3.6) (and yes, I tested it alot - over 20hours on old phone and app still running!).
never happened in emulator
there are no "view resizing" operations running in background, which could cause this exception
I would like to post some code, but I have absolutely no idea where this exception could be thrown.
If someone can help, I'd be really, really grateful. I'm lost at this point...
Since there is not code, this is just a random guess. You can start by looking out for activities in which you've added fragments. It might be that the activity containing a fragment has been destroyed on the device due to inactivity for a long time(and memory requirements by the system, which I think is the reason that you are finding the bug on a device and not on the other). So the case is that the fragment might be referring to a view which might not be attached to the window now. (You can also look for views that use fragment adapters like viewPager, etc if you have used them).
I want the intent I have below to be passed only when the user has passed the login requirements. I tried to put an if statement, in the onClick Listener but it wasn't working out. Basically, once the username and password meets my requirements, I want to pass the intent. If the intent doesn't pass, then I want to pass an else statement saying "That user doesn't exist."

Your attemptLogin(); needs to be called within the else { } of your if.
Currently, it's being called before your if, so it will attempt to login even if your email or password fields are empty.
This was probably just an oversight on your part. If not, you might want to brush on Java by doing the exercises on the following web site. http://codingbat.com/java
So, my app crashes when I press Home button or Back button. I don't know how to solve this issue. Help!!!
public class Game extends SurfaceView implements SurfaceHolder.Callback {
public Game(Context context) {
super(context);
getHolder().addCallback(this);
gameContext = context;
}
...
public void surfaceDestroyed(SurfaceHolder holder) {
boolean retry = true;
updateThread.setRunning(false);
while (retry) {
try {updateThread.join();
retry = false; }
catch (InterruptedException e) {
}
}
}
}
And here is a log of process when I press Home button:

try releasing resources which are consuming memory whenever they are in no use and you can do this in onPause() methods
you can also make some changes in manifiest.xml file like this
<activity android:name="your.package.name.YourActivity" android:configChanges="orientation|keyboard|keyboardHidden|screenLayout|uiMode|screenSize|smallestScreenSize" android:screenOrientation="landscape">
