Hallo,
ich habe Gestern mit der Programierung für Androide angefangen.

Nun bekomme ich es nicht hin das GPS anzusprechen, ich habe schon acht Tutorials zum Thema durch bekomme es aber nicht zum laufen.

Ich hoffe mir kann jemand weiterhelfen.

Androide 8.1
Manifest
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>

MainActivity
Code:
public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = findViewById(R.id.toolbar); setSupportActionBar(toolbar); TrackerService tracker = new TrackerService(this); ((TextView)findViewById(R.id.gpsLatitude)).setText("Latitude: " + tracker.getLatitude()); ((TextView)findViewById(R.id.gpsLongitude)).setText("Longitude: " + tracker.getLongitude()); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { int id = item.getItemId(); if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); }
}
TrackerService
Code:
public class TrackerService extends Service implements LocationListener { private Context context; private LocationManager locationManager; private Location location = null; public TrackerService(Context c) { context = c; LocationManager locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE); boolean enabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); Log.d("isProviderEnabled: ", String.valueOf(enabled)); if (!enabled) { Log.d("isProviderEnabled2: ", String.valueOf(enabled)); Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivity(intent); } locate(); } @SuppressLint("MissingPermission") private void locate() { location = null; try { boolean isGPSActive = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); boolean isNetActive = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER); if (isGPSActive) { Log.d("GPS", "active"); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 30000, 10, this); location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); }else if(isNetActive){ Log.d("NET", "active"); locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,30000,10,this); location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); } }catch (Exception e){ e.printStackTrace(); } } @Override public IBinder onBind(Intent intent) { throw new UnsupportedOperationException("Not yet implemented"); } @Override public void onLocationChanged(Location location) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } @Override public void onProviderEnabled(String provider) { } @Override public void onProviderDisabled(String provider) { } public double getLatitude(){ if (location != null){ return (double)location.getLatitude(); }else { return 0; } } public double getLongitude(){ if (location != null){ return (double)location.getLongitude(); }else { return 0; } }
}

Kann ich die Permission im Konstruktor des Service abfragen oder muss ich das in der Activity abkragen?

Hallo ,

a) Der Logcat sagt nichts aus - Filter ihn mal bitte nach deinem Paket
b) jogi meint , dass es nicht reicht innerhalb der App permissions in der Manifest zu setzen , sondern du musst der App im System
die Erlaubnis durch den User erteilen lassen.
Request App Permissions | Android Developers

Setze zur Probe mal die Berechtigungen manuell.

Anmerkungen :
1) Falls du einen Tracker bauen möchtest , der im Service GPS Koordinaten 24/7 loggt,
so wird dies so nicht funktionieren . (Siehe auch GC und LifeCycle)
2) Tutorials vermitteln nicht die Funktion des Systemes, die bei dieser Anwendung eine erhebliche Rolle spielen.

Und so ganz am Rande : Für einen "Anfänger" mit wenig Erfahrung gleich mit Services zu beginnen,
ist nicht ratsam. In deinem Source fehlen elementare Komponenten.
Copy & Paste bringen dich nicht zum Ziel

Ja aus deinem log kann man dieser nichts nehmen.
In deinen log kann ich nicht mal erkennen das der Konstruktor der Server Klasse aufgerufen wird es gibt vnicht mal das log was du dort aufrufst.
Somit wird der Konstuktor wohl gar nicht aufgerufen. Der Service entspricht auch nicht dem livevcyle.

Die permission solltest du besten am Anfang der app abfragen also in der oncreate und zwar bevor du irgendwie auf das GPS zugreifen tust.

Sorry wegen dem log.

Ich habe jetzt eine Lösung gefunden, habe es leider nicht in den Konstruktor bekommen weil ich ActivityCompat.requestPermissions einfach nicht an die
MainActivity weitergeben konnte.

Code:
public static final String[] myPermissions = new String[]{ Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.INTERNET }; public static final int myRequestCode = 0; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = findViewById(R.id.toolbar); setSupportActionBar(toolbar); showPermission(); for( int i = 0 ; i < myPermissions.length; i++){ requestPermission(myPermissions[i]); }
} private void showPermission() { for (int i = 0; i < myPermissions.length; i++){ int permissionCheck = ContextCompat.checkSelfPermission(this, myPermissions[i]); if (permissionCheck == PackageManager.PERMISSION_GRANTED) { Toast.makeText(this, "permission granted", Toast.LENGTH_LONG).show(); } if (permissionCheck == PackageManager.PERMISSION_DENIED) { Toast.makeText(this, "permission denid", Toast.LENGTH_LONG).show(); } } } private void requestPermission(String mPermissions) { int permissionCheck = ContextCompat.checkSelfPermission(this, mPermissions); if (permissionCheck == PackageManager.PERMISSION_GRANTED) { return; } if (ActivityCompat.shouldShowRequestPermissionRationale(this, mPermissions)) { } ActivityCompat.requestPermissions(this, new String[]{mPermissions} , myRequestCode); }

In der Main activity gibt es keinen Konstruktor dafür bist die onCreate da.

Schaue dir mal die n livevcyle einer activity an.
