Hello, I am new to the app making world and a pretty bad coder while we're at it.
my bmi calculator crashes on launch in the emulator.
here is my code:

public class MainActivity extends AppCompatActivity {
EditText height, weight;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
makwork();
ConvertDouble();
}
public void makwork()
{
height = (EditText) findViewById(R.id.Height);
weight = (EditText) findViewById(R.id.Weight);
}
public void ConvertDouble()

EditText weight = this.weight;
Double H = Double.parseDouble(height.getText().toString());
Double W = Double.parseDouble(weight.getText().toString());
}
public void buttonOnClick(View v) {
makwork();
ConvertDouble();
float h = Float.valueOf(height.getText().toString());
float w = Float.valueOf(weight.getText().toString());
/***

* BMI is calculated
* (weigth in kg / (height in meter * height in meter)

*/
double BMI = w / (h * h) * 10000;
TextView tvBMI = (TextView) findViewById(R.id.BMI);
tvBMI.setText("" + BMI);
}
@override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
how can I prevent it from crashing?
When i run my script below everything works fine. When i want to go back to the previous activity i get a black screen on the emulator and then the app shuts down, i also get a black screen when i exit the application and try to resume it.

I dont get any error message in the log, what i do get is about 13 messages saying "suspending all threads took: X ms" so it has something to the with my gameloop Thread i think. Unfortunately i dont see what the problem is in my code... Can anyone help me with this?
Hi,everyone!
I have a question- how to make all the buttons work, like the button with its ID "button"?
There are 10 buttons (button, button2,3,5,6,7,8,9,10,11) and 10 sounds (bark, bark 2,3,5,6,7,8,9,10,11)

Hi everyone,
I'm working on my first app (still a noob) with Google Maps API v2 in Android Studio and followed a couple of tutorials to get the user's current position and draw a path between two points (not working right now). I am using Retrofit to parse JSON. Now I have a current position and when the user taps the screen, a green marker appears and when the user taps again a red marker appears. Clicking on my driving button to get the route between red and green does nothing.
I would like the current position of the user also to be the starting point (so no extra markers). A user has to be able to enter an address and a new marker has to be set at that address. A route should be drawn between the current position of the user and the new address (showing distance and time) Like Runkeeper, I would like that - when the user moves - the marker at the current position moves with him.
I just can't find any good up to date tutorials which I can use to create this? Is someone able to help me or could someone look at my code? Or know any good tutorials?

Hello !
I'm doing a small personal project with slides and all that, i'm having trouble creating a button with 3 actions depending on witch slide i'm on. I know how to put a different text in my 3 different slides but can't manage to make my buttons work.
Please help !
Code:
public class SliderAdapter extends PagerAdapter {
Context context;
LayoutInflater layoutInflater;
Button slide_btn;
public SliderAdapter(Context context) {
this.context = context;
}
public int[] slide_images = {
R.drawable.small,
R.drawable.medium,
R.drawable.big
};
public String[] slide_headings = {
"*****",
"OKAY",
"WARRIOR"
};
public String[] slide_descs = {
"tutu",
"toto",
"tata"
};
public Button[] getSlide_btn = {
//action1,
//action2,
//action3
};
@Override
public int getCount() {
return slide_headings.length;
}
@Override
public boolean isViewFromObject(@NonNull View view, @NonNull Object o) {
return view == (RelativeLayout) o;
}
@NonNull
@Override
public Object instantiateItem(@NonNull ViewGroup container, int position) {
layoutInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
View view = layoutInflater.inflate(R.layout.slide_layout, container, false);
ImageView slideImageView = (ImageView) view.findViewById(R.id.slide_image);
TextView slideHeading = (TextView) view.findViewById(R.id.slide_heading);
slideImageView.setImageResource(slide_images[position]);
slideHeading.setText(slide_headings[position]);
container.addView(view);
return view;
}
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((RelativeLayout)object);
}
}
I'll take any advice ! Thx !
