BroadcastReceiver übergibt keine Werte an die HomeActivity

[JonasSchmietzer]

Hallo zusammen,

ich möchte mit einen BroadcastReceiver die Information von der Spotify auslesen (Track,Album und Künstler-informationen).
Nur habe ich das Problem,dass keine Werte an die HomeActivity übergegeben werden.

Ich habe die packagename und eine Redirect URI bei Spotify erstellt,somit war auch die Anmeldung über meine App auch möglich.

Nur habe ich das Gefühl, dass der BroadcastReceiver nicht aktiv wird




MainActivity

    private static final int REQUEST_CODE = 1337;
    private static final String CLIENT_ID = "";
    private static final String REDIRECT_URI = "";
    private static final String SCOPES = "";


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        authenticateSpotify();



    }



    private void authenticateSpotify() {
        AuthenticationRequest.Builder builder = new AuthenticationRequest.Builder(CLIENT_ID, AuthenticationResponse.Type.TOKEN, REDIRECT_URI);
        builder.setScopes(new String[]{SCOPES});
        AuthenticationRequest request = builder.build();
        AuthenticationClient.openLoginActivity(this, REQUEST_CODE, request);
    }


    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);

        // Check if result comes from the correct activity
        if (requestCode == REQUEST_CODE) {
            AuthenticationResponse response = AuthenticationClient.getResponse(resultCode, intent);

            switch (response.getType()) {
                // Response was successful and contains auth token
                case TOKEN:
                    // Handle successful response
                   Toast.makeText(getApplicationContext(), "the sign up to spotify was sucessful", Toast.LENGTH_SHORT).show();

                    Intent SwitchToHome = new Intent(MainActivity.this, HomeActivity.class);
                    startActivity(SwitchToHome);
                    finish();

                    break;

                // Auth flow returned an error
                case ERROR:
                    Toast.makeText(getApplicationContext(), "the sign up to spotify was not sucessful", Toast.LENGTH_SHORT).show();
                    // Handle error response
                    break;

                // Most likely auth flow was cancelled
                default:
                    Toast.makeText(getApplicationContext(), "ERROR", Toast.LENGTH_SHORT).show();
                    // Handle other cases
            }


        }
    }

}

(BroadcastSpotify) BroadcastReceiver

public class BroadcastSpotify extends BroadcastReceiver {


    static final class BroadcastTypes {


        static final String SPOTIFY_PACKAGE = "com.spotify.music";
        static final String PLAYBACK_STATE_CHANGED = SPOTIFY_PACKAGE + ".playbackstatechanged";
        static final String QUEUE_CHANGED = SPOTIFY_PACKAGE + ".queuechanged";
        static final String METADATA_CHANGED = SPOTIFY_PACKAGE + ".metadatachanged";
    }


    @Override
    public void onReceive(Context context, Intent intent) {


        // This is sent with all broadcasts, regardless of type. The value is taken from
        // System.currentTimeMillis(), which you can compare to in order to determine how
        // old the event is.
        long timeSentInMs = intent.getLongExtra("timeSent", 0L);


        String action = intent.getAction();

        if (action.equals(BroadcastTypes.METADATA_CHANGED)) {
            String trackId = intent.getStringExtra("id");
            String artistName = intent.getStringExtra("artist");
            String albumName = intent.getStringExtra("album");
            String trackName = intent.getStringExtra("track");
            int trackLengthInSec = intent.getIntExtra("length", 0);


            Intent intentService = new Intent(context, MyService.class);
            // add infos for the service which file to download and where to store
            intentService.putExtra("trackId", trackId);
            intentService.putExtra("artistName", artistName);
            intentService.putExtra("albumName", albumName);
            intentService.putExtra("trackName", trackName);
            intentService.putExtra("trackLengthInSec", trackLengthInSec);

            context.startActivity(intentService);


            // Do something with extracted information...
        } else if (action.equals(BroadcastTypes.PLAYBACK_STATE_CHANGED)) {

            boolean playing = intent.getBooleanExtra("playing", false);

            int positionInMs = intent.getIntExtra("playbackPosition", 0);


            // Do something with extracted information
        } else if (action.equals(BroadcastTypes.QUEUE_CHANGED)) {


        }

    }


}

MyService.java

public class MyService extends Service {



    @Nullable
    @Override

    public IBinder onBind(Intent intent) {
        return null;


    }

    //@Override
    public void onReceive(Intent intent) {

        Log.i("SERVICE-Spotify", "Spotify");
        String trackId = intent.getStringExtra("trackId");

        String albumName = intent.getStringExtra("albumName");
        String trackName = intent.getStringExtra("trackName");
        String trackLengthInSec = intent.getStringExtra("trackLengthInSec");


        Intent myIntent = new Intent(MyService.this, HomeActivity.class);
        myIntent.putExtra("TrackName",trackName);
        myIntent.putExtra("AlbumName",albumName);
        startActivity(myIntent);



    }

 Intent intent = getIntent();
  String  UserId=intent.getStringExtra("TrackName");
  String UserName=intent.getStringExtra("AlbumName");

Toast.makeText(getApplicationContext(),UserId,Toast.LENGTH_SHORT).show();

Hallo Jonas,

in den Foren "tummeln" sich ein und die gleichen wenigen Entwickler.

Demnach dürfte eine Anfrage Deinerseits genügen und es wäre schön ,wenn du auch auf einem Lösungsvorschlag
eingehst, anstatt zu ignorieren. (RemoteLibrary)

Setz dich erst mal damit auseinander und wenn du Fragen hast, kannst du gerne hier nochmal
anfragen .


Hinweis an die anderen Jungs :
Intent überträgt die Variablen nicht an MainActivity.java | AndroidPIT Forum

@swa00 Ich habe es mit der RemoteLibrary geschafft!

Dankeschön!
