Open another activity when dialog's button is pressed?

I'd like to successfully run the code below (belonging to this library) when any of the buttons from this Rating Dialog are pressed. How can I do it?
public void goToPickerActivity() {
Intent intent = new com.sucho.placepicker.PlacePicker.IntentBuilder()
.onlyCoordinates(true) //Get only Coordinates from Place Picker
.showLatLong(true)
.setLatLong(40.71274, -74.005974) // Initial Latitude and Longitude the Map will load into (NYC coordinates)
.setMapZoom(2.5f) // Map Zoom Level. Default: 14.0
.build(this);
startActivityForResult(intent, Constants.PLACE_PICKER_REQUEST);
}
Edit: I want to execute goToPickerActivity() first and then execute the library's intended click code. For example, when Rate App button is clicked:
Step 1 is: execute goToPickerActivity().
Once that's complete, Step 2 is: run the usual Rate App clicked code.

You can try to add a OnRatingDialogListener using setRateButtonText, setRateLaterButtonText or setNeverRateButtonText methods of AppRatingDialog.Builder class:
final AppRatingDialog appRatingDialog = new AppRatingDialog.Builder(this)
// ... call another setup methods if need
.setRateButtonText("Rate App", new OnRatingDialogListener() {
#Override
public void onClick() {
goToPickerActivity();
}
})
.setRateLaterButtonText("Rate App Later", new OnRatingDialogListener() {
#Override
public void onClick() {
goToPickerActivity();
}
})
.setNeverRateButtonText("Never", new OnRatingDialogListener() {
#Override
public void onClick() {
goToPickerActivity();
}
})
.build();
appRatingDialog.show();
Using lambda it will look like this:
final AppRatingDialog appRatingDialog = new AppRatingDialog.Builder(this)
// ... call another setup methods if need
.setRateButtonText("Rate App", () -> goToPickerActivity())
.setRateLaterButtonText("Rate App Later", () -> goToPickerActivity())
.setNeverRateButtonText("Never", () -> goToPickerActivity())
.build();
appRatingDialog.show();
EDIT 1:
Method openPlayStore:
private void openPlayStore() {
final String storeLink = "market://details?id=" + context.getPackageName();
final Uri marketUri = Uri.parse(storeLink);
try {
mContext.startActivity(new Intent(Intent.ACTION_VIEW, marketUri));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(mContext, "Couldn't find PlayStore on this device", Toast.LENGTH_SHORT).show();
}
}
If you can edit the library try to make openPlayStore method public, save reference to AppRatingDialog instanse to some variable, e.g. appRatingDialog and call appRatingDialog.openPlayStore().
EDIT 2:
To have different listeners for buttons we need to add new listeners to AppRatingDialog and handle them:
public class AppRatingDialog extends AppCompatDialog implements View.OnClickListener {
//...
private OnRatingDialogListener onRatingDialogListener;
private OnRatingDialogListener onRateLaterDialogListener;
private OnRatingDialogListener onRateNeverDialogListener;
//...
#Override
public void onClick(View v) {
if (v.getId() == R.id.dialog_rating_button_never_rate) {
savedNeverShow();
dismiss();
if (onRateNeverDialogListener != null) {
onRateNeverDialogListener.onClick();
}
} else if (v.getId() == R.id.dialog_rating_button_rate_later) {
dismiss();
incrementLaunchCount(true);
if (onRateLaterDialogListener != null) {
onRateLaterDialogListener.onClick();
}
} else if (v.getId() == R.id.dialog_rating_button_rate) {
savedNeverShow();
dismiss();
if (onRatingDialogListener != null) {
onRatingDialogListener.onClick();
} else {
openPlayStore();
}
}
}
// ...
public static class Builder {
//...
#NonNull
public Builder setRateLaterButtonText(String rateLaterButtonText, #Nullable OnRatingDialogListener onRateLaterClickListener) {
appRatingDialog.mRateLaterButtonText = rateLaterButtonText;
appRatingDialog.onRateLaterDialogListener = onRateLaterClickListener;
return this;
}
#NonNull
public Builder setNeverRateButtonText(String neverRateButtonText, #Nullable OnRatingDialogListener onNeverRateClickListener) {
appRatingDialog.mNeverRateButtonText = neverRateButtonText;
appRatingDialog.onRateNeverDialogListener = onNeverRateClickListener;
return this;
}
// ...
}
}
EDIT 3:
To open Play Store and notify a listener simultaneously:
public class AppRatingDialog extends AppCompatDialog implements View.OnClickListener {
//...
private OnRatingDialogListener onRatingDialogListener;
private OnRatingDialogListener onRateLaterDialogListener;
private OnRatingDialogListener onRateNeverDialogListener;
//...
#Override
public void onClick(View v) {
if (v.getId() == R.id.dialog_rating_button_never_rate) {
savedNeverShow();
dismiss();
if (onRateNeverDialogListener != null) {
onRateNeverDialogListener.onClick();
}
} else if (v.getId() == R.id.dialog_rating_button_rate_later) {
dismiss();
incrementLaunchCount(true);
if (onRateLaterDialogListener != null) {
onRateLaterDialogListener.onClick();
}
} else if (v.getId() == R.id.dialog_rating_button_rate) {
savedNeverShow();
dismiss();
openPlayStore();
if (onRatingDialogListener != null) {
onRatingDialogListener.onClick();
}
}
}
// ...
}

Please follow these steps:
In the library module look for class called AppRatingDialog.java add YOURACTIVITY.goToPickerActivity(**boolean**); to each view of onClick (at line 171) method like this one:
#Override
public void onClick(View v) {
if (v.getId() == R.id.dialog_rating_button_never_rate) {
YOURACTIVITY.goToPickerActivity(false);
savedNeverShow();
dismiss();
if (onRatingDialogListener != null) {
onRatingDialogListener.onClick();
}
} else if (v.getId() == R.id.dialog_rating_button_rate_later) {
YOURACTIVITY.goToPickerActivity(false);
dismiss();
incrementLaunchCount(true);
if (onRatingDialogListener != null) {
onRatingDialogListener.onClick();
}
} else if (v.getId() == R.id.dialog_rating_button_rate) {
YOURACTIVITY.goToPickerActivity(true);
savedNeverShow();
dismiss();
if (onRatingDialogListener != null) {
onRatingDialogListener.onClick();
}
}
}
In your activity modify your method goToPickerActivity() to be something like this:
private static void goToPickerActivity(boolean isRate) {
Intent intent = new com.sucho.placepicker.PlacePicker.IntentBuilder()
.onlyCoordinates(true) //Get only Coordinates from Place Picker
.showLatLong(true)
.setLatLong(40.71274, -74.005974) // Initial Latitude and Longitude the Map will load into (NYC coordinates)
.setMapZoom(2.5f) // Map Zoom Level. Default: 14.0
.build(this);
if (isRate){
startActivityForResult(intent, Constants.PLACE_PICKER_REQUEST_RATE);
} else {
startActivityForResult(intent, Constants.PLACE_PICKER_REQUEST);
}
in method onActivityResult check the request code if it's equal to Constants.PLACE_PICKER_REQUEST_RATE then call method openStore():
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
if (requestCode == Constants.PLACE_PICKER_REQUEST_RATE) {
//other code ...
openStore();
}
}
}
private void openStore() {
final Uri storeUri = Uri.parse(mStoreLink); // your app store listing link
try {
startActivity(new Intent(Intent.ACTION_VIEW, storeUri));
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
}
You can add handler to openStore() if you want to wait for certain time before go to store page:
Handler mHandler = new Handler();
mHandler.postDelayed(() -> {
openStore();
}, 1000); // wait for 1 second

You can simply write a class and extend from AppRatingDialog. then by overriding onClick method you can do what you want. then by calling super.onClick you'll run the library onClick method.
#Override
public void onClick(View v) {
if (v.getId() == R.id.dialog_rating_button_rate) {
goToPickerActivity();
}
super.onClick(v);
}

As you are able to edit the library code, to match up your requirement, first of all, change appratingdialog library code. Go to AppRatingDialog.java and inside onClick(View v) modify the rating button condition like below:
if (v.getId() == R.id.dialog_rating_button_rate) {
savedNeverShow();
dismiss();
if (onRatingDialogListener != null) {
onRatingDialogListener.onClick();
openPlayStore(); // Just added this extra line here, others are kept in place
} else {
openPlayStore();
}
}
Now, inside your app activity, create custom click listener for rating button using setRateButtonText like below:
AppRatingDialog appRatingDialog = new AppRatingDialog.Builder(MainActivity.this)
.setTriggerCount(3)
.setRepeatCount(4)
.setRateButtonText("Rate Now", clickListener)
.build();
appRatingDialog.show();
Finally, implement the click listener inside your app activity having the PlacePicker intent inside onClick like below:
OnRatingDialogListener clickListener = new OnRatingDialogListener() {
#Override
public void onClick() {
goToPickerActivity();
}
};

You actually seem to have this already answered in your original post.
startActivityForResult(intent, Constants.PLACE_PICKER_REQUEST);
public void goToPickerActivity() {
Intent intent = new com.sucho.placepicker.PlacePicker.IntentBuilder()
.onlyCoordinates(true) //Get only Coordinates from Place Picker
.showLatLong(true)
.setLatLong(40.71274, -74.005974) // Initial Latitude and Longitude the Map will load into (NYC coordinates)
.setMapZoom(2.5f) // Map Zoom Level. Default: 14.0
.build(this);
startActivityForResult(intent, Constants.PLACE_PICKER_REQUEST);
}
So override onActivityResult() from within there you can determine if the activity was successful and then do what you need like below
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (!(requestCode == 0 && resultCode == RESULT_OK)){
onBackPressed();
}else{
goToPickerActivity()
}
}

Try to update these following dependencies in your build.gradle project level:
classpath 'com.android.tools.build:gradle:3.6.3'
classpath 'com.github.dcendents:android-maven-gradle-plugin:$the_latest_version'

Playing multiple sounds via multiple buttons from raw in background using service

I want to play 6 different sounds triggered by 6 different buttons in background, so that if the app is on background the sound keeps playing.
When one sound is already playing, pressing another button will stop it and play its own sound,
Tapping the same button 2K times it stops, 2K+1 times: starts again.. (K is a non-null integer)
All of the code is done and seems to be working correctly, except that the player stops after one and a half minute. (This is not because of low memory)
Can anyone please tell me what am I doing wrong?
public class PlayService extends Service {
private MediaPlayer player;
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
player = new MediaPlayer();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
int btnId = intent.getExtras().getInt("ID");
Toast.makeText(this, "onStart service" + btnId, Toast.LENGTH_SHORT).show();
selectResId(btnId);
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service destroyed", Toast.LENGTH_SHORT).show();
if (player != null) {
player.stop();
player.release();
}
player = null;
}
#Override
public void onLowMemory() {
super.onLowMemory();
Toast.makeText(this, "Low mem", Toast.LENGTH_SHORT).show();
}
private void selectResId(int resId){
switch (resId){
case 1: playMediaFromResource(R.raw.number_one);
case 2: playMediaFromResource(R.raw.number_two);
case 3: playMediaFromResource(R.raw.number_three);
case 4: playMediaFromResource(R.raw.number_four);
case 5: playMediaFromResource(R.raw.number_five);
case 6: playMediaFromResource(R.raw.number_six);
default: break;
}
}
private void playMediaFromResource(int resId) {
Uri mediaPath = Uri.parse("android.resource://" + getPackageName() + "/" + resId);
try {
player.setDataSource(getApplicationContext(), mediaPath);
player.setLooping(true);
player.prepare();
player.start();
} catch (Exception e) {
e.printStackTrace();
}
}
}
And the MainActivity:
public class MainActivity extends AppCompatActivity {
private Button btnStart1;
private Button btnStart2;
private Button btnStart3;
private Button btnStart4;
private Button btnStart5;
private Button btnStart6;
private Intent intent;
private int previousID = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewsByIds();
setOnClickListeners();
}
private void findViewsByIds() {
btnStart1 = findViewById(R.id.btn_start_1);
btnStart2 = findViewById(R.id.btn_start_2);
btnStart3 = findViewById(R.id.btn_start_3);
btnStart4 = findViewById(R.id.btn_start_4);
btnStart5 = findViewById(R.id.btn_start_5);
btnStart6 = findViewById(R.id.btn_start_6);
}
private void setOnClickListeners() {
btnStart1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkIntentState(1);
}
});
btnStart2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkIntentState(2);
}
});
btnStart3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkIntentState(3);
}
});
btnStart4.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkIntentState(4);
}
});
btnStart5.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkIntentState(5);
}
});
btnStart6.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkIntentState(6);
}
});
}
private void checkIntentState(int ID) {
if (intent == null) {
createNewIntent(ID);
} else {
stopService(intent);
intent = null;
if (ID != previousID) {
createNewIntent(ID);
}
}
}
private void createNewIntent(int ID) {
intent = new Intent(MainActivity.this, PlayService.class);
intent.putExtra("ID", ID);
startService(intent);
previousID = ID;
}
}

I want to answer to my own question just in case anyone else runs into the problem.
It turns out, that Android added some new features (restricted access to background resources for battery life improvement purposes since Oreo(i.e. Android 8.0+ || API level 26)).
As the documentation says:
"Apps that are running in the background now have limits on how freely they can access background services."
So, in this case we will need to use foreground services.

Voice Recognition without Google Dialog

I am trying to use the Speech recognition without dialog with RecognitionListener, but it doesn't work. The following codes are the way now I use, and the bottom codes (test part) are for checking that could phone receive my commanding. Additionally, I have added permissions Audio. Finally, I don't want there have any button.
This is my first time asking question, so hope I dont violate any unspoken rules.
Thank you very much,

cannot run android text to speech

My code is as follows
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
runBtn = (Button)findViewById(R.id.button_run_demo);
ttobj = new TextToSpeech(getApplicationContext(),
new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
ttobj.setLanguage(Locale.UK);
}
}
});
runBtn.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
});
}
public void onPause() {
if (ttobj != null) {
ttobj.stop();
ttobj.shutdown();
}
super.onPause();
}
public void speakText(String text) {
String toSpeak = text;
Toast.makeText(getApplicationContext(), toSpeak,
Toast.LENGTH_SHORT).show();
ttobj.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
//do my stuff
speakText("Hello");
}
}
Although I am able to do my stuff I am not able to run speech.
Am I missing something ??
Thanks All

When onActivityResult() is called the TextToSpeech is already shutdown since you shut it down in onPause(). You have to either set a flag to speak "Hello" when TextToSpeech is reinitialize or put your code in onPause() in onDestroy().

In App Purchases Not Saving Shared Preferences

I have an android application similar to wheel of fortune where users have the option to purchase one consumable, $1000, and two entitlements, where they unlock two images as wheel styles. I am using the Amazon In-App Purchasing API. The user should be able to purchase as many consumables as they want but once they purchase the entitlements the unlocked image should be the only image that they see and they should no longer see the locked image. These in-app purchases work fine the first instance I initiate these purchases.
However, the consumable field will only update once and even though I can still go through the process of completing purchases for the consumable, the text view containing the score, or money, does not update other then that first initial purchase. Also the wheels return to the locked image rather then remaining as the unlocked image despite the fact that when I initiate the purchase for these entitlements I am told that I already own these items. Therefore I believe it may be something to do with my SharedPreferences. In short my purchases update my views once and then never again, however the backend code i.e the responses I receive from the Amazon client when completing purchases are correct. Can anyone see where I have made a mistake? Why does the textView containing the score update on the 1st purchase and never again from then on? Also how do I save the changes toe the wheel style so that when it reopens they no longer have the option to purchase the wheel? I have three classes and have included the code below. All and any help is greatly appreciated.

It could be that you are not using the same editor.
preferences.edit().putString(PreferenceKey.DISTANCE, distance);
preferences.edit().commit();
two different SharedPreferences.Editors are being returned. Hence the
value is not being committed. Instead, you have to use:
SharedPreferences.Editor spe = preferences.edit();
spe.putString(PreferenceKey.DISTANCE, distance);
spe.commit();
