Settings.ACTION_SOUND_SETTINGS is not going back to app

I am trying to open Sound settings from my app
startActivity(new Intent(Settings.ACTION_SOUND_SETTINGS));
Sound Settings Activity displays without any issue.
Scenarios After Opening Sound settings page
When I press back button on my device, it is going back to my application.
when I click on back arrow button(top left), it is going to Settings Main Screen.
Issue:
I want to go back to my app when click on back icon also.
startActivityForResult(new Intent(Settings.ACTION_SOUND_SETTINGS), 100);
I have also tried this. but no result.
I am testing this on OnePlus 6 (Android 10 (Q))

Create an intent:
Intent intent = new Intent(Settings.ACTION_SOUND_SETTINGS);
Add these lines to your intent:
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
intent.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
then call startActivity(intent);

Is there a way to use the APIs of online streaming apps (Gaana/Saavn/Wync Music/Spotify/Google Music) to play songs directly from another app?

I want to create an Android app which can play songs from cloud (using Saavn/Google Music/ Hungama/Gaana/Spotify/SoundCloud etc.) using some APIs or intents. Is there any way to do that?
I already tried by passing as an intent_action_media_play_from_search from my app but that doesn't play song directly through the streaming app and it shows ambiguous screen.
And in google music it plays some random radio corresponding that.
try {
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setAction(MediaStore.INTENT_ACTION_MEDIA_PLAY_FROM_SEARCH);
/* intent.setComponent(new ComponentName(
"com.google.android.music",
"com.google.android.music.ui.search.VoiceActionsActivity"));*/
//intent.putExtra(SearchManager.QUERY, "Song_name");
intent.putExtra(SearchManager.QUERY, "Song_name");
v.getContext().startActivity(intent);
}
I expect it to play the searched song directly or if possible using some APIs, I may receive the ambiguous results and then play with some particular id.

Android open external IMDB application from my app

I have a button in my application which opens the imdb application in the phone with a imdb id I received from https://developers.themoviedb.org/3/getting-started/introduction
But I couldnt find anyway(using intents) to make my app recognize the imdb app and open it and if imdb app do not exist then I want to open the web site. How can I accomplish this?

I think I may be able to point you in the right direction. Just to be sure, you seem to be using TMDB but wish to open in the IMDB app?
The code below is from the Android documentation.
It will start your intent if the package manager can find an app with the appropriate intent filter installed on your device. If multiple apps are able to open this intent then an app chooser should pop up, unless the user has previously set a default for this kind of URI.
Intent sendIntent = new Intent(Intent.ACTION_SEND);
// Always use string resources for UI text.
// This says something like "Share this photo with"
String title = getResources().getString(R.string.chooser_title);
// Create intent to show the chooser dialog
Intent chooser = Intent.createChooser(sendIntent, title);
// Verify the original intent will resolve to at least one activity
if (sendIntent.resolveActivity(getPackageManager()) != null) {
startActivity(chooser);
}
If you add an else onto that then you can use a view intent like this :
Intent internetIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(movieUrl));
//Watch out here , There is a URI and Uri class!!!!
if (internetIntent.resolveActivity(getPackageManager()) != null){
startActivity(internetIntent);
}
I also found this (rather old) post about calling an explicit imdb uri
Imdb description
startActivity(android.intent.action.VIEW, imdb:///title/<titleID>);
// take note of the Uri scheme "imdb"
I hope this helps. If you post some more detail , code, links , I might be able to work through this with you.
If my answer is way off base then please be kind and set me right. We are all learning every day!
Good Luck.

Android Home Shortcut loses flags after reboot

My Android app defines an activity with an intent filter of android.intent.action.CREATE_SHORTCUT, which lets me show up in the list of shortcuts that the user can add to their home page, when they select "Add Shortcut" from the menu or long-click the home page.
In this activity I have the following code (actually happens in a click event after they pick which shortcut to add):
Intent shortcutIntent = new Intent(this,MyActivity.class);
shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ShortcutIconResource iconResource = Intent.ShortcutIconResource.fromContext(this, R.drawable.myicon);
Intent intent = new Intent();
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "MyAppName");
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);
setResult(RESULT_OK, intent);
finish();
The shortcut works as I would expect, until I reboot the device. I'm actually testing on the emulator, not real device. The shortcut is still there after a reboot, so I know I didn't wipe user data or anything like that, but it acts like it no longer has the FLAG_ACTIVITY_NEW_TASK setting when clicked.
Example steps to recreate (assume my app is an email inbox for clarity):
Create the shortcut
Launch my inbox activity from my main menu acitvity, which uses the NEW_TASK flag.
From the inbox activity, click a message to open the view message activity.
Press HOME key
Click the shortcut -- at this point it brings the entire "task stack" back to the front, with the view message activity on top of the stack, clicking back goes back to the inbox activity, as I would expect
Reboot the device
Repeat steps 2 through 5.. now when I click the shortcut, instead of bringing the view message activity to the front, it brings the task to the front, but then adds a new inbox activity on top of the stack. So pressing BACK once goes back to the view message activity, and back again to the inbox activity.
I also tried setting different properties such as singleTask for my inbox activity in the app manifest, but haven't had any luck. Is this a known issue that flags are not saved with shortcuts?
I think I'll try adding a new stub activity that does nothing but launches the real activity with the NEW_TASK flag and then exits, and have my shortcuts point to that instead. However, seems like a lot of overhead, so hopefully someone has a better answer.

Button to start the Gallery on Android

I'm trying to make a button in my App open the built in gallery.
public void onClick(View v) {
Intent intentBrowseFiles = new Intent(Intent.ACTION_VIEW);
intentBrowseFiles.setType("image/*");
intentBrowseFiles.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intentBrowseFiles);
}
This results in an error message "The application Camera (process com.android.gallery) has stopped unexpectedly."
If I set the Intent action to ACTION_GET_CONTENT it manages to open the gallery but then simply returns the image to my app when a picture is selected which is not what I want.

I'm trying to make a button in my App open the built in browser.
Your question subject says "Gallery". Your first sentence in the question says "browser". These are not the same thing.
If I set the Intent action to ACTION_GET_CONTENT it manages to open the gallery but then simply returns the image to my app when a picture is selected which is not what I want.
Of course, actually telling us "what [you] want" would just be too useful, so you are making us guess.
I am going to go out on a limb and guess that you are trying to open the Gallery application just as a normal application. Note that there is no Gallery application in the Android OS. There may or may not be a Gallery application on any given device, and it may or may not be one from the Android open source project.
However, for devices that have the Android Market on them, they should support an ACTION_VIEW Intent with a MIME type obtained from android.provider.MediaStore.Images.Media.CONTENT_TYPE.
