# Setting up a android app
|
|
|
|
## How to make your project from a empty project
|
|
|
|
### Layout
|
|
You first need to make the layout of the app. This can be done in the res folder where you can make a android recource file. When you open that file you can drag and drop elements in the layout.
|
|
|
|
### Code
|
|
Then need to make the main class. The class will probably look like this.
|
|
|
|
```java
|
|
package com.fitbot.fitbot;
|
|
|
|
import android.os.Bundle;
|
|
import androidx.appcompat.app.AppCompatActivity;
|
|
|
|
public class MainActivity extends AppCompatActivity {
|
|
@Override
|
|
protected void onCreate(Bundle savedInstanceState) {
|
|
super.onCreate(savedInstanceState);
|
|
// set activity_main to your respective layout file
|
|
setContentView(R.layout.activity_main);
|
|
}
|
|
}
|
|
```
|
|
With setContentView you can set the layout file that you made earlier.
|
|
``` java
|
|
setContentView(R.layout.activity_main);
|
|
```
|
|
|
|
### Manifest
|
|
For the app to be able to build you need to add the activity class to the manifest file.
|
|
|
|
```xml
|
|
<activity android:name=".MainActivity"
|
|
android:exported="true">
|
|
<intent-filter>
|
|
<action android:name="android.intent.action.MAIN"/>
|
|
<category android:name="android.intent.category.LAUNCHER"/>
|
|
</intent-filter>
|
|
</activity>
|
|
```
|
|
In this instance MainActivity is the first class that is ran. |
