    <p>So I have an activity in an application that starts a service:</p> <pre><code>private void startService() { if (started) { Toast.makeText(Main.this, "Service already started", Toast.LENGTH_SHORT).show(); } else { Intent i = new Intent(); i.setClassName("com.enorbitas.daemon.service", "com.enorbitas.daemon.service.DaemonService"); startService(i); started = true; updateServiceStatus(); Log.d(getClass().getSimpleName(), "startService()"); } } </code></pre> <p>The activity is launched by the following intent:</p> <pre><code>&lt;intent-filter&gt; &lt;action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" /&gt; &lt;/intent-filter&gt; </code></pre> <p>The service then does the logging and connects with this custom usb device. In order to do that, it needs the activity context:</p> <pre><code> mUsbManager = (UsbManager) parent.getSystemService(Context.USB_SERVICE); HashMap&lt;String, UsbDevice&gt; deviceList = mUsbManager.getDeviceList(); Iterator&lt;UsbDevice&gt; deviceIterator = deviceList.values().iterator(); while(deviceIterator.hasNext()){ UsbDevice device = deviceIterator.next(); } Intent intent = parent.getIntent(); String action = intent.getAction(); UsbDevice device = (UsbDevice) intent .getParcelableExtra(UsbManager.EXTRA_DEVICE); if (UsbManager.ACTION_USB_DEVICE_ATTACHED.equals(action)) { setDevice(device); Log.i(TAG, "usb conectado"); } else if (UsbManager.ACTION_USB_DEVICE_DETACHED.equals(action)) { if (mDevice != null &amp;&amp; mDevice.equals(device)) { setDevice(null); Log.i(TAG, "usb NO conectado"); } } </code></pre> <p>parent would be the activity that starts the service. This approach used to work because that code used to be in the same application, but now I want it to be a service so that others applications can connect to it.</p> <p>Is there a way to pass the context of the activity to the service? I read a lot about intents and bundles, parcelable and serialization, but none of it works for me. I need to pass the context.</p> <p>Any ideas? </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
