I'm trying to implement a temperature sensor on a virtual Pixel 4a, Ambient Temp sensor is included according to list of sensors.
When I run the program, the textView continues to print "Hello world!" instead of what setText in the onSensorChanged method provides.
Here is my code, any help will be amazing:
public class MainActivity extends AppCompatActivity implements SensorEventListener {
private SensorManager sensorManager;
private TextView textView;
private Sensor tempSensor;
private Boolean tempSensorAvailable;
private int activityCode = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (ContextCompat.checkSelfPermission(MainActivity.this,
Manifest.permission.ACTIVITY_RECOGNITION)
!= PackageManager.PERMISSION_GRANTED) {
requestActivityPermission();
}
textView = findViewById(R.id.textView);
sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
if (sensorManager.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE) != null) {
tempSensor = sensorManager.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE);
tempSensorAvailable = true;
} else {
textView.setText("Temperature Sensor is not available.");
tempSensorAvailable = false;
}
}
#Override
public void onSensorChanged(SensorEvent sensorEvent) {
textView.setText(sensorEvent.values[0] + " Celsius");
}
#Override
public void onAccuracyChanged(Sensor sensor, int i) {
}
#Override
protected void onResume() {
super.onResume();
if (tempSensorAvailable) {
sensorManager.registerListener(this, tempSensor,
SensorManager.SENSOR_DELAY_NORMAL);
}
}
#Override
protected void onPause() {
super.onPause();
if (tempSensorAvailable) {
sensorManager.unregisterListener(this);
}
}
public void requestActivityPermission() {
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.
ACTIVITY_RECOGNITION)) {
new AlertDialog.Builder(this)
.setTitle("Permission needed")
.setMessage("Permission is needed to run this app.")
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.ACTIVITY_RECOGNITION},
activityCode);
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
})
.create().show();
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACTIVITY_RECOGNITION},
activityCode);
}
}
You mus call SensroManager.registerListener():

I am using sinch Video calling API for my android application. But when the app is in the background, whenever the user is offline i.e user cleared app from the recent tab, he was unable to get the call. I used Firebase for pushing notification whenever the user is offline, but it is not getting triggered all the time, it is getting triggered sometimes only. can anyone suggest me how to push notification of incoming call when the user cleared the app from recent and will sinch actually run in the background?

I am using Room Database with LiveData , but my Local Database is updating too fast as per our requirement and at the same time i have to reload my recycler view .instead of calling notifyDataSetChanged() to adapter , i am trying to use DiffUtil , but is crashing or not reloading properly , this is uncertain .
i am following this tutorial :

I'm trying to send sensor data from my wear device to the handheld. The problem is that the onMessageReceived function of my WearableListenerService is never called, even though it gets created.
The package names of the wear and mobile apps are the same, also here's the entry for the service in the manifest file:
<service
android:name=".WatchDataReceiver"
android:enabled="true"
android:exported="true" >
</service>
On my handheld in the MainActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
startService(new Intent(this, WatchDataReceiver.class));
setContentView(R.layout.activity_fullscreen);
...
}
On my handheld, the service:
public class WatchDataReceiver extends WearableListenerService {
#Override
public void onCreate() {
super.onCreate();
Log.i(WatchDataReceiver.class.getSimpleName(), "WEAR create");
}
#Override
public void onDataChanged(DataEventBuffer dataEvents) {
Log.i(WatchDataReceiver.class.getSimpleName(), "WEAR Data changed " );
}
#Override
public void onMessageReceived(MessageEvent messageEvent) {
Log.i(WatchDataReceiver.class.getSimpleName(), "WEAR Message " + messageEvent.getPath());
}
}
On the watch/wear:
public class MainActivity extends Activity implements SensorEventListener {
private static final String LOG_TAG = "Watch: ";
private SensorManager sensorManager;
private Sensor accelerometer;
private GoogleApiClient mGoogleApiClient;
private String msg = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
#Override
public void onLayoutInflated(WatchViewStub stub) {
mTextView = (TextView) stub.findViewById(R.id.text);
}
});
sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
accelerometer = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
sensorManager.registerListener(this, accelerometer, SensorManager.SENSOR_DELAY_FASTEST);
if (accelerometer != null) {
Log.v(LOG_TAG, "Accelerometer registered!");
}
else {
Log.v(LOG_TAG, "Accelerometer _not_ registered!");
}
mGoogleApiClient = new GoogleApiClient.Builder(this).addApi(Wearable.API).build();
mGoogleApiClient.connect();
}
#Override
public void onSensorChanged(SensorEvent event) {
if(event.sensor.getType() == Sensor.TYPE_ACCELEROMETER && event.values.length > 0) {
double value_x = event.values[0];
double value_y = event.values[1];
double value_z = event.values[2];
msg = Double.toString(value_x) + ";" + Double.toString(value_y) + ";" + Double.toString(value_z);
sendMessageToHandheld(msg);
}
}
#Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
//TODO
}
private void sendMessageToHandheld(String msg) {
if (mGoogleApiClient == null)
return;
final String message = msg;
Log.d(LOG_TAG,"sending a message to handheld: "+message);
// use the api client to send the heartbeat value to our handheld
final PendingResult<NodeApi.GetConnectedNodesResult> nodes = Wearable.NodeApi.getConnectedNodes(mGoogleApiClient);
nodes.setResultCallback(new ResultCallback<NodeApi.GetConnectedNodesResult>() {
#Override
public void onResult(NodeApi.GetConnectedNodesResult result) {
final List<Node> nodes = result.getNodes();
if (nodes != null) {
for (int i=0; i<nodes.size(); i++) {
final Node node = nodes.get(i);
Wearable.MessageApi.sendMessage(mGoogleApiClient, node.getId(), message, null);
}
}
}
});
}
}
According to LogCat the correct handheld is found because in sendMessageToHandheld right after the actual sendMessage it do a Log.d with the name of the node.
What am I missing?
You have to add this IntentFilter to your service:
<intent-filter>
<action android:name="com.google.android.gms.wearable.BIND_LISTENER" />
</intent-filter>
It tells the system to take care of the Service lifecycle (ie starting it if needed).
I am adding my two separate android activities in one application, one of my activity having volley library but it gives me an exception that appcontroller(volley library) its an application not an activity please help me out
Ya, you have mention in your manifest file appcontroller class as Application. This solves the exception.
