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.
The code for running the application in the background

#Override
public void onCreate() {
super.onCreate();
createNotificationChannel();
}
private void createNotificationChannel() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel serviceChannel = new NotificationChannel(
CHANNEL_ID,
"Example Service Channel",
NotificationManager.IMPORTANCE_DEFAULT
);
NotificationManager manager =
getSystemService(NotificationManager.class);
manager.createNotificationChannel(serviceChannel);
}
}

Can someone call me this code in my app?

the following code should turn on the camera and record video on my android phone. However, nothing happens. Anybody spot any errors in my code?

I have used this code to create (trying) an app that opens its camera and starts recording videos, whether front or back, doesn't matter. But what ever i have tried i cannot seem to get it to work. When i press the button, nothing happens, no crash, no new view. I am not sure what the problem is.

AND here is the xml file for main activity:

I think you forgot to register an "onClickListener" with your button:
startRecording.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
startRecording();
}
});

My application won't change launch activity

I have tried to change the launch activity but am met with a blank screen saying "method" (which is pulled from #new_name string).
I tried to change it so that MainMenu would launch instead of activity_main

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);

Android moving strip like Sliding Drawer

I try to realise following view in androind application.
In my programm i want to divide the main activity between two.
Now it does't work propertly. I want, that the line between two
windows in activity is moveable and the line can divide the whole screen in
different proportion. Not only to show whole one window or another.
Image for understanding enter link description here
My programm looks like:
MainActivity.java

Unfortunately myandroidapps has stopped

I am very new to android apps development. I successfully signed my apps and installed on my phone Android Ver. 4.1.2. The codes below are my codes. May I know what is wrong? Thanks guys/girls :)

you forget to declare MainActivity Activity in AndroidManifest.xml. add it as:
....
<activity android:name=".MainActivity" />
....
</application>
