Unable to receive broadcast message android

I have registered "SMS received event" for the broadcast receiver but when i launch the app and send message to the emulator i do not see onReceive method of broadcast receiver getting triggered.
AndroidManifest.xml

I think you need to check permission in code for SDK more or equal to M(Marshmallow) -
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
{
if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission. RECEIVE_SMS) == PackageManager.PERMISSION_GRANTED) {
// you can receive sms
}
else
{
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission. RECEIVE_SMS}, 411);
}
}
else
{
// you can receive sms
}
}
And on result of user action-
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 411) {
if (grantResults.length == 0 || grantResults == null) {
// show dialog that you need access to go ahead
} else if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Your code here permission granted
} else if (grantResults[0] == PackageManager.PERMISSION_DENIED) {
// show dialog that you need access to go ahead
}
}
}

The android.permission.RECEIVE_SMS permission is a dangerous permission.
You should use ActivityCompat.requestPermissions to request it.
<permission android:name="android.permission.RECEIVE_SMS"
android:permissionGroup="android.permission-group.UNDEFINED"
android:label="#string/permlab_receiveSms"
android:description="#string/permdesc_receiveSms"
android:permissionFlags="hardRestricted"
android:protectionLevel="dangerous" />

Cannot activate my custom permission in my code

I want to ask users to agree with the disclaimer that I have provided in my application, and then if they agreed, next time they are using the app, we just re-show them the disclaimer for a few seconds without asking to click on anything and redirect them to the application. The best way I could have come up with it was, using a custom permission and however I did add permission commands to my manifest I could not figure out how to actually activate the permission in my code:
import java.util.jar.Manifest;
public class Language extends Activity {
Button engBut, fraBut;
// public static int j;
public void click (View view){
// j=1;
Intent intent = new Intent(getApplicationContext(),MainActivity.class);
startActivity(intent);
}
public void fraClick (View view){
// j=2;
Intent intent = new Intent(getApplicationContext(),MainActivity.class);
startActivity(intent);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_language);
ImageView logo = (ImageView) findViewById(R.id.logo);
ImageView montfortLogo = (ImageView) findViewById(R.id.montfortLogo);
montfortLogo.setImageResource(R.drawable.k);
logo.setImageResource(R.drawable.j);
engBut = (Button) findViewById(R.id.engBut);
engBut.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
AlertDialog.Builder builder = new AlertDialog.Builder(Language.this);
builder.setCancelable(true);
builder.setTitle("DISCLAIMER");
builder.setMessage(R.string.result_disclaimer);
builder.setNegativeButton("Get me out of here.", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.cancel();
}
});
builder.setPositiveButton("I agree.", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Intent intent = new Intent(getApplicationContext(),MainActivity.class);
intent.setAction("com.techideas4you.pharamacy.MyAction");
intent.addCategory("android.intent.category.DEFAULT");
startActivity(intent);
}
});
builder.show();
}
});
fraBut = (Button) findViewById(R.id.fraBut);
Log.i("Locale", String.valueOf(Locale.getDefault()));
}
}
This was my first page code.

You have to add android:protectionLevel="dangerous" to the declaration of your permission else it will be granted automatically and users will not be presented with a dialog although you call requestPermission().
<permission android:name="your.package.name.permission.testDisclaimer" android:label="DISCLAIMER"
android:description="#string/result_disclaimer"
android:protectionLevel="dangerous"/>
<uses-permission android:name="your.package.name.permission.testDisclaimer"/>
In order to have the runtime show the disclaimer, you have to call
requestPermissions(new String[]{"your.package.name.permission.testDisclaimer"}, 42);
The result (whether user agreed) will be transmitted to you in onRequestPermissionsResult()
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults)
{
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 42 && grantResults != null){
Toast.makeText(this, "Permission " + permissions[0] + (grantResults[0] == PERMISSION_GRANTED ? "" : " NOT ") + " granted! ", Toast.LENGTH_LONG).show();
}
}
Please note that by using the permission system, you also have to cope with the fact that users will NOT be shown the permission-request-disguised-as-disclaimer if they
[...] turned down the permission request in the past and chose the
Don't ask again option in the permission request system dialog [...]
(quoted from documentation).
So maybe simply writing a flag to SharedPreferences will do the job just as well.

To obtain the current location

I am using the below code to obtain the location of a user
public class MainLocation extends Application implements LocationListener {
protected LocationManager locationManager;
protected LocationListener locationListener;
protected Context context;
String lat;
String provider;
protected String latitude, longitude;
protected boolean gps_enabled, network_enabled;
#Override
public void onCreate() {
super.onCreate();
Log.e("Location", "here");
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// public void requestPermissions(#NonNull String[] permissions, int requestCode)
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for Activity#requestPermissions for more details.
return;
}
}
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
#Override
public void onLocationChanged(Location location) {
Log.e("Location", "" + location.getLatitude());
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.e("Location Status", "" + provider + " " + status + " " + extras);
}
#Override
public void onProviderEnabled(String provider) {
Log.e("Location", "Enabled");
}
#Override
public void onProviderDisabled(String provider) {
Log.e("Location","Disabled"+provider);
}
}
but here the onLocationChanged function is never getting called, so i m not able fetch the location. So how can i get the location?
In the logcat, the info tab is showing the latitude and longitude under the title onLocationReceived".

here is the push image
push details

This is what I did for a chat app I made, every time a user sings up on your app, suscribe it to a channel with their user id. That way you will have an unique channel for every user and you can send individual pushes to them.
Here is a quick code I put up:
ParseUser user = new ParseUser();
user.setUsername("my name");
user.setPassword("my pass");
user.setEmail("email#example.com");
// other fields can be set just like with ParseObject
user.put("phone", "650-253-0000");
user.signUpInBackground(new SignUpCallback() {
public void done(ParseException e) {
if (e == null) {
String userID = user.getObjectId();
ParsePush.subscribeInBackground(userID});
} else {
// Sign up didn't succeed. Look at the ParseException
// to figure out what went wrong
}
}
});
After this you just need the userid of the receiver and that's it.

Is client push enabled in the parse application settings ?
It's disabled by default.
More infomation can be found at the parse blog:

Parse.initialize freezes my app

I recently upgraded my parse-*.jar files to version 1.10.0
After cleaning up my project at android studio and syncing with gradle, suddenly my app freezes at start... blackscreen, without any button working (I need to force-close the app)
I searched the net and this site for solutions, but couldn't find anything.
Any help will be much appreciated!
My Application class:
public class Application extends android.app.Application {
#Override
public void onCreate() {
super.onCreate();
Log.d("app", "reached1");
// Enable Local Datastore.

Log.d("app", "reached2");
ParseObject.registerSubclass(FoodListItem.class);
Log.d("app", "reached3");
Parse.initialize(this, "STRING1", "STRING2");
Log.d("app", "reached4");
ParseInstallation.getCurrentInstallation().saveInBackground();
Log.d("app", "reached5");
ParsePush.subscribeInBackground("", new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
Log.d("app", "successfully subscribed to the broadcast channel.");
} else {
Log.e("app", "failed to subscribe for push", e);
}
}
});
}

Shouldn't you initialize the parse sdk before anything else
public class Application extends android.app.Application {
#Override
public void onCreate() {
super.onCreate();
Parse.initialize(this, "STRING1", "STRING2");
Parse.enableLocalDatastore(this);
ParseObject.registerSubclass(FoodListItem.class);
ParseInstallation.getCurrentInstallation().saveInBackground();
ParsePush.subscribeInBackground("", new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
Log.d("app", "successfully subscribed to the broadcast channel.");
} else {
Log.e("app", "failed to subscribe for push", e);
}
}
});
}

To anyone who might be concerned, Apparently there was no Internet connection for the phone (because it automatically went into USB tethering and something went wrong over there) so that when parse got initialized it tried to connect to the server AT THE MAIN THREAD without success, causing the freeze effect.
The solution was to check for the phone's connectivity BEFORE starting parse, so my final solution was -
public class Application extends android.app.Application {
#Override
public void onCreate() {
super.onCreate();
Log.d("app", "reached1");
if (!connectedToInternet()) {
Log.e("app", "not connected to internet. exiting");
exitAppWithDialog(this);
}
....
}
I chose one of the methods to check connectivity which exist here -
