Custom quick settings. Tile stays inaccessible when attached to action.

Question

I am trying to add a custom quick settings panel for my application. I have been following the sample code / documentation from Google, but I am facing some problems. After some searching, I could not find any solutions.

When I launch my application, the tile is displayed in the quick settings panel, but it remains inaccessible.

I need a two-way communication flow with the tile, that is, when the user selects the tile, the application responds, and when the user performs a specific action in the application, the tile user interface switches.

The problem seems to be related to trying to bind my custom class TileServiceto mine MainActivity- whenever I bind this when the tile goes into unchanged state. I can’t understand why, though, because it is successfully connected. If I do not bind it (i.e., it just has a one-way connection between the command control), the tile is active, and the application responds to its selection.

Ultimately, I get attached to the link to my custom class TileServicein order to be able to call the method toggleTileUI(). I do not want to use a singleton or static member variable as a solution to get a link to my service.

Here is what I have in mine AndroidManifest.xml:

        <service
            android:name=".ConnectionQuickSettingsService"
            android:label="@string/quick_setting_tile_connect"
            android:icon="@drawable/tile_icon"
                android:permission="android.permission.BIND_QUICK_SETTINGS_TILE">
            <intent-filter>
                <action android:name="android.service.quicksettings.action.QS_TILE" />
            </intent-filter>
        </service>

Here's mine ConnectionQuickSettingsService.java:

@TargetApi(24)
public class ConnectionQuickSettingsService extends TileService {
    private static final String TAG = "ConnectionQuickSettingsService";
    private final IBinder mBinder = new LocalBinder();

    public class LocalBinder extends Binder {
            ConnectionQuickSettingsService getService() {
                return ConnectionQuickSettingsService.this;
            }
    }

    @Override
    public IBinder onBind(Intent i) {
        return mBinder;
    }

    @Override
    public void onTileAdded() {
        L.d(TAG, "onTileAdded()");
    }

    @Override
    public void onStartListening() {
        L.d(TAG, "onStartListening()");
    }

    @Override
    public void onClick() {
        L.d(TAG, "Quick Settings tile selected");
        toggleInAppSwitch();
        toggleTileUI();
    }

    private void toggleInAppSwitch() {
        doStuff();
    }

    public void toggleTileUI() {
        Tile tile = this.getQsTile();
        doStuffWithTile();
    }

}

and finally (corresponding parts) my MainActivity.java:

@Override
protected void onStart() {
    super.onStart();
    Intent i = new Intent(this, ConnectionQuickSettingsService.class);
    bindService(i, mConnection, Context.BIND_AUTO_CREATE);
}

@Override
protected void onStop() {
    super.onStop();
    if (mBound) {
        unbindService(mConnection);
        mBound = false;
    }
}

private ServiceConnection mConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName className,
                                   IBinder service) {
        ConnectionQuickSettingsService.LocalBinder binder = (ConnectionQuickSettingsService.LocalBinder) service;
        mQSService = binder.getService();
        mBound = true;
        L.d(TAG, "Bound to QS service successfully");
}

    @Override
    public void onServiceDisconnected(ComponentName arg0) {
        mBound = false;
        L.d(TAG, "Disconnected from QS service");
    }
};

public void onOnOff(){
    L.d(TAG, "On/Off switch toggled");
    if (mBound) {
        mQSService.toggleTileUI();
    }
}

Any input would be appreciated, thanks!

Answer 1

, onBind(), TileService onBind(), Android ConnectionQuickSettingsService. , LogCat , .

, , getQsTile() . .

, , META_DATA_ACTIVE_TILE requestListeningState(), Binder onBind().

Answer 2

, . META_DATA_ACTIVE_TILE , TileService.requestListeningState(, ComponentName (, TileService.class)), onStartListening(). onStartListening() // Tile.

Tile if (getQsTile!= Null)
