[Resolved] [Q] Android App Problem (Linking list items to the android market)

Hey guys,
I need some help with my first app.
I cannot post this in the Anddev section because of my low post count, so I apologize that this goes here.
I want to link some list positions to the respective android market pages. My current code looks like this:
Code:
package com.asm.reader;
import java.util.ArrayList;
import java.util.Arrays;
import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
public class TitlesActivity extends ListActivity {
/** Called when the activity is first created. */
String[] links = {
"Get Full Version", "Get Reading Sample 2", "Get Reading Sample 3", "Get Reading Sample 4", "Get Reading Sample 5",
"Get Story 2", "Get Story 3", "Get Story 4", "Get Story 5"};
private ArrayAdapter<String> adapter;
private String selectedItem;
private final Context context = this;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
OnItemClickListener itemListener = new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View arg1, int position,
long arg3) {
}
};
ArrayList<String> list = new ArrayList<String>(Arrays.asList(links));
adapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
list);
setListAdapter(adapter);
getListView().setOnItemClickListener(itemListener);
}
}
The dev guide says I have to do this:
Code:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=com.android.example"));
startActivity(intent);
But how do I set it with the right position?
Thanks a lot in advance, I hope you guys can help me out a little bit.

API 19 and Bluetooth Low Energy

I am currently working on a project to connect a Google Glass Explorer Edition (Android Kitkat and therefore API 19) to an Arduino board emitting data in BLE.
I have checked that this is possible and I have found and installed an APK that manages to make the link. However, I want to make a slightly different application.
The application I want to make has a splash screen and a main activity displaying the different values on TextView. This part is already working.
Splash Screen:
Java:
package com.example.flyin_glass;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import androidx.appcompat.app.AppCompatActivity;
/* loaded from: classes.dex */
public class SplashScreenActivity extends AppCompatActivity {
/* JADX INFO: Access modifiers changed from: protected */
@Override // androidx.fragment.app.FragmentActivity, androidx.activity.ComponentActivity, androidx.core.app.ComponentActivity, android.app.Activity
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
Runnable runnable = new Runnable() { // from class: com.example.myapplication.SplashScreenActivity.1
@Override // java.lang.Runnable
public void run()
{
Intent intent = new Intent(SplashScreenActivity.this.getApplicationContext(), MainActivity.class);
SplashScreenActivity.this.startActivity(intent);
SplashScreenActivity.this.finish();
}
};
new Handler().postDelayed(runnable, 3000L);
}
}
Main activity :
Java:
package com.example.flyin_glass;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import android.Manifest;
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.*;
import android.bluetooth.le.*;
import android.content.pm.PackageManager;
import android.os.Build;
import android.os.Bundle;
import android.os.Handler;
import android.util.Log;
import android.content.Context;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
My goal would be to code (in main activity) the management of the BLE, i.e. the automatic connection to my Arduino (which has a specific UUID) as well as the data retrieval and display in TextView.
Being a novice in Android development, the task of managing the BLE is very complex for me. Do you have any advice?
Thank you in advance.
