Pass username to another activity with RewardedAd

The problem is that I am trying to pass the name of the user when the adReward is complete to another activity. But I'm stuck in this activity, even though the video ad is loaded. (and it works well while there are no video ad to show). Here is my code:
My java.class
public class TheDay1 extends AppCompatActivity implements RewardedVideoAdListener {
Vibrator vibrator;
private RewardedVideoAd HDay1;
int currentActivity = 0;
boolean flag;
private EditText vname;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_the_day1);
vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
MobileAds.initialize(this,
"ca-app-pub-3940256099942544/6300978111");
///ADD BAN
AdView mAdView = findViewById(R.id.banner1);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
///////////////////////////////////
//VIDEO
HDay1 = MobileAds.getRewardedVideoAdInstance(this);
HDay1.setRewardedVideoAdListener(this);
loadRewardedVideoDAY1();
vname = findViewById(R.id.name);
final ImageView nm = findViewById(R.id.ID);
nm.setVisibility(View.INVISIBLE);
ColorMatrix matrix = new ColorMatrix();
matrix.setSaturation(0);
ColorMatrixColorFilter filter = new ColorMatrixColorFilter(matrix);
nm.setColorFilter(filter);
final Button closeAd = findViewById(R.id.closeDay1);
closeAd.setVisibility(View.INVISIBLE);
///////////////////////////////////////////////////////////////////////////////////////////
closeAd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
vibrator.vibrate(50);
loadRewardedVideoDAY1();
if (HDay1.isLoaded()) {
HDay1.show();
setCurrent(1);
}
String name = vname.getText().toString();
getusername(name);
}
});
}
////////////////////////////////////////////////////////////////
private void Day1() {
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
}
private void getusername(String name) {
Intent intent = new Intent(this, ActivityTwo.class);
Resources resources = getResources();
String key = resources.getString(R.string.key_name);
intent.putExtra(key, name);
startActivity(intent);
}
private void loadRewardedVideoDAY1() {
if (!HDay1.isLoaded()) {
HDay1 = null;
HDay1 = MobileAds.getRewardedVideoAdInstance(this);
HDay1.setRewardedVideoAdListener(this);
///////////////TEST ID//////////////////
HDay1.loadAd("ca-app-pub-3940256099942544/5224354917", new AdRequest.Builder().build());
}
}
#Override

}
#Override

}
#Override
public void onRewardedVideoAdClosed() {
loadRewardedVideoDAY1();
if (currentActivity == 1) {
Day1();
}
}
#Override
public void onRewarded(RewardItem rewardItem) {
loadRewardedVideoDAY1();
flag = true;
if (currentActivity == 1) {
Day1();
}
}
#Override

super.onPause();
}
#Override

}

}
Any idea what the problem could be? Thanks in advance

Try below code. Update ProcessData with your intent logic and update oncreate with other data required in your class
public class TheDay1 extends AppCompatActivity implements RewardedVideoAdListener {

#Override
public void onResume() {
super.onResume();

}
}
#Override
public void onPause() {
super.onPause();
if (mRewardedVideoAd != null) {
mRewardedVideoAd.pause(this);
}
}
#Override
public void onDestroy() {
super.onDestroy();
if (mRewardedVideoAd != null) {
mRewardedVideoAd.destroy(this);
}
}
#Override
public void onRewardedVideoCompleted() {
//Toast.makeText(this, "onRewardedVideoCompleted", Toast.LENGTH_SHORT).show();
}
#Override
public void onRewardedVideoAdLoaded() {

if (bRewardVideo) {
ProcessData();
} else {
Toast.makeText(this, "Please View Reward Video to get Reward Points", Toast.LENGTH_LONG).show();

loadRewardedVideoAd();

Scanning for bluetooth devices programmatically don't find anything in android 6+

I created an application which pairs a cellphone to a bluetooth module.
i tested this application with a 4.2 android cellphone and it worked quite well but in cellphones with android higher than 6 the device is not fidning anything when i press " Scan for new devices " button.
but when i go through my phone bluetooth itself, i can find the module i was looking for..

in an article i studied about this issue and find out that with this code :
if (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(context,
new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
1);
i can make the application to support phones with android more than 6 so i can discover all nearby devices and pair with them,
The issue is, i don't know where should i exactly use this code..
i would really appreciate if you could tell me where to use it within the codes i showed here.
or simply tell me how to overcome this problem with any other code you may know.

In your AndroidManifest.xml file add this:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Then, instead of calling registerReceiver call this function:
private tryRegisterReceiver() {
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
// Here, permission is not granted
// after calling requestPermissions, the result must be treated in onRequestPermissionResult
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
1000); // 100 or other desired code
} else {
// Permission has already been granted
// continue registering your receiver
registerReceiver();
}
}
To treat the result of the permission request
#Override
public void onRequestPermissionsResult(int requestCode,
String[] permissions, int[] grantResults) {
switch (requestCode) {
case 1000: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted
// continue registering your receiver
registerReceiver();
} else {
// permission denied
// show a message or finish your activity
}
return;
}
// other 'case' for other permissions if needed
}
}

save url when re rotate screen from landscape to protrit

I'm trying to play video on player and the video is url that I fetch from an api
so I have a channels in recycleview1 and when I click on one channel the channel start play in new activity
in that activity the player take half of screen and the rest is for recycleview2 which contain some channels for easy and fast navigate between channels
so when I open the channel from recycleview1 and it start playing then I rotate the screen to landscape it work fine then restore the screen to portrate again the channel still working
but the problem is when I click on channel from recycleview2 which lead to update the url that already played and start the new one
so each time I click on channel from recycleview2 the videoview updated to new channel url that clicked
I face problem when I rotate the screen after played channel from recycleview2 the videoview start play a channel that I clicked from recyclewview1 before clicking on new channel from recycleview2 because it return to onCreate method which build the url depend on the information passed with on click
so I used to save the instance state of url so when I rotate the screen to landscape the vidoeview still played the last channel that played
but the problem is when I re rotate the screen to portrate again the videoview here return to the first channel played when start the activity
I tried to save instance state too but it doesn't working
this is the code:
public class TVChannel extends AppCompatActivity implements
TVAdapter.TVAdapterOnClickHandler {
private VideoView videoView;
private int position = 0;
private String video;
private MediaController mediaController;
String mChannelTitle;

you can see that I use:
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
}
else{
}
to set content view for portrait and landscape
and inside else this is the code that I use to save the url in landscape mode:
if (savedInstanceState != null){
myBoolean = savedInstanceState.getString("video");
Toast.makeText(this, "This is my Toast message!",
Toast.LENGTH_LONG).show();
videoView.setVideoURI(Uri.parse(myBoolean));
}
else {
String host = "http://ip/";
String app = mChannelApp;
String streamname = mChannelStreamname;
String playlist = "playlist.m3u8";
vidUri = Uri.parse(host).buildUpon()
.appendPath(app)
.appendPath(streamname)
.appendPath(playlist)
.build();
videoView.setVideoURI(vidUri);
}
and if savedInstanceState null so build url like this from on click information that I pass in portrait mode:
channelObject = getIntent().getParcelableExtra("TVChannel");
if (channelObject != null) {
mChannelTitle = String.valueOf(channelObject.getTitle());
mChannelApp = String.valueOf(channelObject.getApp());
mChannelStreamname = String.valueOf(channelObject.getStreamName());
mChannelCat = String.valueOf(channelObject.getCat());
}
how can I save the url channel when I re rotate screen from landscape to portrait mode again?

Does Service needs another parser?

I have already been fetched data from instagram api. But i cannot reach that data to use it on my service. I have tried all methods that i know.
**Here is my main object: ** If my followers count is increases or decreases, notify, And check that for every 5 min.(I am still working on it. There are lots of misses yet.)
**Here is my main question: ** Do i really have to create a new parser to fetch data that i already have or what should i build?
If you have any sample or Articles for this case, that would be useful.
I heard about Csv file. Is that can be useful to import ?
PS: I learned java and android studio yet. I am pretty newbie.

The only solution that i found is the adding parser to your service to reach data from api. None of the the method can access to reach data from service to activity.
I added this class to reach api data on service.
public void lilParser() throws IOException, JSONException{
URL url = new URL(API_URL + "/users/" + mSession.getId()
+ "/?access_token=" + mAccessToken);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoInput(true);
urlConnection.connect();
String response = Utils.streamToString(urlConnection
.getInputStream());
System.out.println(response);
JSONObject jsonObj = (JSONObject) new JSONTokener(response).nextValue();
JSONObject data_obj = jsonObj.getJSONObject("data");
JSONObject counts_obj = data_obj.getJSONObject("counts");
String name = jsonObj.getJSONObject("data").getString("full_name");
String bio =jsonObj.getJSONObject("data").getString("bio");
String counts=jsonObj.getJSONObject("data").getString("counts");
userInfoHashmap.put(TAG_FOLLOWED_BY,counts_obj.getString(TAG_FOLLOWED_BY));
Log.i(TAG,"followedby=>[" + counts + "]");
}
And, Here is my onCreate. You can check The data if it is changed or not.
#Override
public void onCreate() {
Toast.makeText(this,"Service Started", Toast.LENGTH_LONG).show();
myTimer = new Timer();
myTimer.schedule(new TimerTask() {
#Override
public void run() {
String fo = userInfoHashmap.get(TAG_FOLLOWED_BY);
try {
lilParser();
}
catch (IOException e) {e.printStackTrace();}
catch (JSONException e) {e.printStackTrace();}
if(new String(userInfoHashmap.get(TAG_FOLLOWED_BY)).equals(fo)==true){}
else {
getnotification();
}
}
}, 0, 30000);
}
PS: I published my code, that may help someone else. I am still newbie.

How will I stop the music when I went to another activity which is CatActivity?

I am making a game app but the music still keeps playing even when I closed the game. how to stop? and how to change background music once I go to another activity after I clicked a button
public class BackgroundSoundService extends Service {
private static final String TAG = null;
MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
#Override

super.onCreate();
player = MediaPlayer.create(this, R.raw.rysk);
player.setLooping(true); // Set looping
player.setVolume(100,100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return 1;
}
public void onStart(Intent intent, int startId) {
// TO DO
}
public IBinder onUnBind(Intent arg0) {
// TO DO Auto-generated method
return null;
}
public void onStop() {
}
public void onPause() {
}
#Override
public void onDestroy() {
player.stop();
player.release();
}
#Override

}
}
this is my main activity (PlayActivity.class)
Intent svc=new Intent(this, BackgroundSoundService.class);
startService(svc);
I want to change the music when I clicked a button and went to CatActivity

You need to stop the player in onPause(). Following code can be used:
#Override
protected void onPause() {
super.onPause();
if (this.isFinishing()){
player.stop();
}
}
Check Android Stop Background Music for more details

for that you should stop the service in the onCreate method of the Activity. Below is the code for it :
stopService(new Intent(MyService.MY_SERVICE));
Best of Luck!

In Your MainActivity , You Should Call stopService() Inside MainActivity
#Override
public void OnPause() {
stopService(svc);
}
