Closing the app when user cancels immediate in app update

Currently i'm implementing the in app update feature from android. I'm using the immediate update method, the problem that I'm facing is that when the UI prompting the user to update shows and the user does not click the update button instead they click the cross button. The UI for the app update just closes and user can continue using the app.
What I want is that when user click the cross button the app immediately closes, until user updates the app then they can use the app as usual. I also uses the java code for the android development.

The image I borrowed from google, on the left image as can be seen there is a cross button on top right user can click to close the update process

The most important point I will emphasize is that you should not force users to update the app until it is absolutely necessary (like some security issues etc). Forcing updates to users is considered a very bad user experience.
To the question you asked, you have the answer in your question itself. If you check the code you have something like this in your onActivityResult method-
if (requestCode == RC_APP_UPDATE) {
//when user clicks update button
if (resultCode == RESULT_OK) {
Toast.makeText(LoginActivity.this, "App download starts...", Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
//if you want to request the update again just call checkUpdate()
Toast.makeText(LoginActivity.this, "App download canceled.", Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_IN_APP_UPDATE_FAILED) {
Toast.makeText(LoginActivity.this, "App download failed.", Toast.LENGTH_LONG).show();
}
}
In case when the user cancels resultCode == RESULT_CANCELED or the update fails resultCode == RESULT_IN_APP_UPDATE_FAILED, you can take whatever action you want. You can finish the activity or whatever is suitable in your situation.

How can I check if a telephone number exist programmatically?

I want to do an Android App that check if a number exist or not. In particular I was thinking of calling the number to check and if it ring it means that exist, otherwise it does not.
At the moment I can read the state "IDLE" and "OFFHOOK" but not the state "CALL_STATE_RINGING" that as far as I understood trigger only for received call.
How can I understand when it is ringing and when the number is not valid?
Note: The calling approach is just an idea but I could accept others solutions if they are effective.
My code at the moment:
Listener:
public class EndCallListener extends PhoneStateListener {
private String TAG = "CALL_AUTOMATICALLY_LISTENER";
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if(TelephonyManager.CALL_STATE_RINGING == state) {
// TODO
Log.i(TAG, "RINGING, number: " + incomingNumber);
}
if(TelephonyManager.CALL_STATE_OFFHOOK == state) {
Log.i(TAG, "OFFHOOK");
}
if(TelephonyManager.CALL_STATE_IDLE == state) {
Log.i(TAG, "IDLE");
}
}
}
public class MainActivity extends AppCompatActivity {
private String TAG = "CALL_AUTOMATICALLY";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
askPermission();
}
private void askPermission() {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE},0);
}
public void startCall(View view) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
String number = "+39555555555"; // fake number
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" + number));
// Activate listener
EndCallListener callListener = new EndCallListener();
TelephonyManager mTM = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
if (mTM != null) mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
else Log.d(TAG, "TelephonyManager null");
// start call
startActivity(intent);
} else {
askPermission();
}
}
}
public void startCallNotExisting(View view) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
String number = "+39456464564545555565656565";
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" + number));
// Activate listener
EndCallListener callListener = new EndCallListener();
TelephonyManager mTM = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
if (mTM != null) mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
else Log.d(TAG, "TelephonyManager null");
// start call
startActivity(intent);
} else {
askPermission();
}
}
}
}

I suggest you check phone number regex instead of calling them.place this method in your helper or activity or fragment class
public static boolean validateMobile(String mobile) {
if (mobile.matches("^[+]?[0-9]{10,13}$")) {
return true;
} else {
return false;
}
}
And use it like
if(Helper.validateMobile(mobile){
//mobile is valid
}else{
//mobile is not valid}
also this regex can be different if you target one specific country.for example i use below regex for iran phone numbers
(\\+98|0)?9\\d{9}

Before intent is changing spinner also change its value

After I press the button "ΕΙΣΟΔΟΣ" a new intent is called and the spinner change its value, to first item. Although it does not effect my app, it is disturbing. I cannot find where the issue is...

Video that represents how my app is behaving. I have searched but couldn't find anything.

I think (but not 100% sure) it may be due to activity live cycle: onStop() method is invoked, which erase local data from your spinner and jumps to begenning of the array linked to AdapterView.
Overload onSaveInstanceState:
onSaveInstanceState(Bundle outState){
outState.putInt("position", [variable with chosen position])
}
And add to onCreate:
if(savedInstanceState!=null){
[variable with chosen position] = savedInstanceState.getInt("position");
// with that variable set position in your spinner here
}
Although I don't know if adding in onCreate() will do.
You can also try overloading OnStop() and setting spinner value.
Hope that helps

Where exactly to insert onPause() in Android?

Sorry for this question, I'm a beginner.
My first app has been rejected due to violating the Device and Network Abuse policy.
Edit: Main reason is that Youtube video doesn't stop playing when the display is turned off...

Volating the Device and Network Abuse policy

Anywhere you want inside your Activity class (the one you pasted in your question).
I usually try to order my lifecycle methods in the order Android executes them, so I'd put it after onResume()
#Override
public void onResume() {
super.onResume();
asm_view.onResume(); //remember to add this so your WebView can resume
//Coloring the "recent apps" tab header; doing it onResume, as an insurance
if (Build.VERSION.SDK_INT >= 23) {
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
ActivityManager.TaskDescription taskDesc;
taskDesc = new ActivityManager.TaskDescription(getString(R.string.app_name), bm, getColor(R.color.colorPrimary));
MainActivity.this.setTaskDescription(taskDesc);
}
get_location();
}
#Ovveride
public void onPause() {
super.onPause();
asw_view.onPause(); //your WebView variable is asm_view, not mWebView, which is just example code
}

onPause is a lifecycle method of Activity (and Fragments) and can be placed anywhere in the Activity class but putting your lifecycle methods in the order they are executed will help making your code more readable.

android - Google places opens the map on closes after 1 sec

Im creating an intent to an activity by clicking on a button which should open google places, but it closes again really fast and says no location selected, and returns to the main activity, and then nothing happens if i click again.
My api should be fine, I have checked that it's the correct SHA1-fingerprint thats connected to the api key.
The result code is 2
It worked earlier in the activity before this one, but I needed it to open when i click on a button instead, and now when I try to open this new activity as an intent it wont work.
public class MapActivity extends AppCompatActivity {
int PLACE_PICKER_REQUEST = 1;
int status;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_events);
status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (status != ConnectionResult.SUCCESS) {
if (GooglePlayServicesUtil.isUserRecoverableError(status)) {
GooglePlayServicesUtil.getErrorDialog(status, this,
100).show();
}
}
if (status == ConnectionResult.SUCCESS) {
int PLACE_PICKER_REQUEST = 199;
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
Context context = this;
try {
startActivityForResult(builder.build(context), PLACE_PICKER_REQUEST);
} catch (GooglePlayServicesRepairableException e) {
e.printStackTrace();
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
System.out.println("Result code: " + resultCode);
System.out.println("Request code: " + requestCode);
if (requestCode == 100) {
status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
}
if (requestCode == 199) {
//process Intent......
if (data != null) {
Place place = PlacePicker.getPlace(data, this);
String toastMsg = String.format("Place: %s", place.getName());
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
} else {
String toastMsg = ("No location selected.");
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
}
}
}
}
This is from the intent which create the new intent to maps
public void onClick(View view) {
Intent i = new Intent(this, MapActivity.class);
startActivity(i);
}

I think its happening because of you are using old method of getPlace
try to swap the arguments, by changing it from:
Place place = PlacePicker.getPlace(data, this);
to
Place place = PlacePicker.getPlace(getContext(), data);
Update #2
Enable Google places API in the developer console and add these lines to AndroidManifest
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="ADD_YOUR_API_KEY_HERE" />
Update #3
after some search, it looks like there is others having same issue. Look at these links:
