Receiver doesnt know when to invoke itself.

You need to specify when to invoke it.

Where ever you want to call the next activity use this:-
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);

Theres no code to navigate to MainActivity
Trigger below code
private void startMainActivity(){
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
}

You have to start your second activity
startActivity(new Intent(getApplicationContext(), MainActivity.class));
make sure that you have added second activity in manifest file

void SwitchButton() {
btn_right = (Button) findViewById(R.id.btn_right);
btn_left = (Button) findViewById(R.id.btn_left);
btn_right.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
current_image_index++;
current_image_index = current_image_index % images.length;
imageView.setImageResource(images[current_image_index]);
startMainPage();
}
});
btn_left.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
current_image_index--;
if (current_image_index < 0) {
current_image_index = images.length - 1;
}
imageView.setImageResource(images[current_image_index]);
startMainPage();
}
}
);
}
private void startMainPage() {
Intent intent = new Intent(Login.this, MainActivity.class);
startActivity(intent);
}

write this code in your click listener:
btn_right.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
current_image_index++;
current_image_index = current_image_index % images.length;
imageView.setImageResource(images[current_image_index]);
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
}
});

Call measure how far you dragged in Android

I made an application running in the background, and I want to add a function to measure the slide on the screen. I'll leave you the code for both, and someone can help me. I'm a beginner and I've been looking all over trying to solve this without results.
I know the post is too long, but I did not know how to shorten it so you can understand it.

Can someone call me this code in my app?

LogCat won't show anything at all for some reason. I'll see if I can figure out why and update with that.

You need to change this
protected void onCreate11(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainmenu);
}
to
Button button,button1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainmenu);
button = (Button) findViewById(R.id.button9);
button1 = (Button) findViewById(R.id.button1);
addListenerOnButtonNews();
addListenerOnButtonGPS()
}
Also change to
public void addListenerOnButtonNews() {
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(getApplicationContext(), NewActivity.class);
startActivity(intent);
}
});
}
public void addListenerOnButtonGPS() {
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
}});
}
