how to get a list of the installed audio players? - java

Is it possible to get a list of the installed audio players?
I guess I could do that as following.
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_SEND);
intent.setType("audio/*");
List<ResolveInfo> apps = getPackageManager().queryIntentActivities(intent, 0);
But I got nothing.
Could anyone help me? T_T


Try this:
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI,"1");
intent.setData(uri);
intent.setType("audio/*");
List<ResolveInfo> apps = getPackageManager().queryIntentActivities(intent, 0);
for (ResolveInfo rInfo : apps) {
//process list here
}


This code sniper lets you choose at first from you're installed audio players and then gives opportunity to play music from them.
Intent intent = new Intent(Intent.ACTION_GET_CONTENT, MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
intent.setType("audio/mpeg3");
startActivityForResult(intent, REQUEST_CODE);

Please teach me.

If viber application is installed in your device, You can call an intent to share the text.
boolean found = false;
Intent share = new Intent(android.content.Intent.ACTION_SEND);
share.setType("text/plain");
// gets the list of intents that can be loaded.
List<ResolveInfo> resInfo = context.getPackageManager()
.queryIntentActivities(share, 0);
if (!resInfo.isEmpty()) {
for (ResolveInfo info : resInfo) {
if (info.activityInfo.packageName.toLowerCase(
Locale.getDefault()).contains("com.viber.voip")
|| info.activityInfo.name.toLowerCase(
Locale.getDefault()).contains("com.viber.voip")) {
share.putExtra(Intent.EXTRA_TEXT, "Your text to share");
share.setPackage(info.activityInfo.packageName);
found = true;
context.startActivity(Intent.createChooser(share, "Select"));
break;
}
}
if (!found) {
displayToast(context, "Install viber android application");
Uri marketUri = Uri.parse("market://details?id="
+ "com.viber.voip");
Intent marketIntent = new Intent(Intent.ACTION_VIEW, marketUri);
context.startActivity(marketIntent);
}
}
I am not sure it will work. But it will worth a shot.
You can also share with the plain intent which asks the user to select and share :
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/html");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml("<p>This is the text that will be shared.</p>"));
startActivity(Intent.createChooser(sharingIntent,"Share using"));

How can I create and start an Intent?

I was wondering how I can create and start an intent using this:
"qsrtech.posprintdriver/.printservice"
I downloaded the POS Printer Driver (ESC) app (which is the app I am trying to access).
I tried this:
String PrintPage = "qsrtech.posprintdriver/.printservice";
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(ComponentName.unflattenFromString(PrintPage));
intent.addCategory(Intent.CATEGORY_LAUNCHER );
startActivity(intent);
However, I get an error saying:
"No activity found to handle this intent"
I was wondering if there is anything I can do to access this intent? The thing is that I'm not sure if I'm accessing an activity or a background service (probably an intent service?) from a different app.
Here is the link that explains more about this intent.
http://www.qsrtechnologies.com/aboutposdriver.html

You can try with this :
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra("Data", "Test printer\n\n");
sendIntent.setComponent(new ComponentName("qsrtech.posprintdriver","qsrtech.posprintdriver.printservice"));
startService(sendIntent);

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra("Data", "Test printer\n\n");
sendIntent.setComponent(new ComponentName("qsrtech.posprintdriver","qsrtech.posprintdriver.printservice"));
startService(sendIntent);
Worked like a charm here.

How do i launch the music player

How am i suppose to use this
android.intent.category.APP_MUSIC
to launch the music player?
it doesn't work if i call makeMainSelectorActivity
Intent intent = new Intent();
intent.makeMainSelectorActivity(intent.ACTION_MAIN,
"android.intent.category.APP_MUSIC");
startActivity(intent);

This solution might help someone looking to launch default Music Player:
if(android.os.Build.VERSION.SDK_INT>=15){
Intent intent=Intent.makeMainSelectorActivity(Intent.ACTION_MAIN,
Intent.CATEGORY_APP_MUSIC);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//Min SDK 15
startActivity(intent);
}else{
Intent intent = new Intent("android.intent.action.MUSIC_PLAYER");//Min SDK 8
startActivity(intent);
}

Used below code :
Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1");
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
or
Intent intent = new Intent("android.intent.action.MUSIC_PLAYER");
startActivity(intent);
Ans also prefer url :
Launching the default music player

How to make a button that functions as a link in eclipse for android

I need to know how I could make a button that opens the androids web browser and navigates to a specific URL. I'm using eclipse and already know how to make buttons and click listeners.
Thanks for any help.

Just add this code to onClick():
// Launch a browser
Uri uri = Uri.parse("http://www.yahoo.com");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

Intent websiteIntent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.parse("http://www.android.com");
websiteIntent.setData(uri);
startActivity(websiteIntent);

Try this
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com");
startActivity(intent);

Where is a list of available intents in Android?

I'm starting to learn how to develop apps for Android, and I'm having some issues with intents--it just doesn't seem like they're documented at all. All I want to do is send the user to the video recorder, where they record a video, and the video information is returned to my app. I know this is possible, as I've seen it in other apps, but it seems like the intent is undocumented (or I'm just not completely understanding how intents work).
Any thoughts?

Apart from above solutions, here are a list of common intents
//show web page intent:
Uri uri = Uri.parse("http://www.google.com");
Intent it = new Intent(Intent.ACTION_VIEW,uri);

Intent it = new Intent(Intent.ACTION_VIEW,URI);
startActivity(it);
//call dial program
Uri uri = Uri.parse("tel:xxxxxx");
Intent it = new Intent(Intent.ACTION_DIAL, uri);
startActivity(it);

In general, the Android developer docs are a good place to look for this kind of thing: there's a list of common intent actions in the Intent class reference. For recording video, check out the ACTION_VIDEO_CAPTURE intent action defined by the Media provider.

You might want to check out OpenIntents

This is relatively new from Google (they seem to have updated their old page which just showed Intents for standard Google apps).
Common Intents
It tells you exact Intent specification for performing a wide range of actions with apps for the following:
Alarm Clock
Camera
Calendar
Contacts / People
Email
File Storage
Maps
Music / Video
Phone Dialler
Settings
Text Messaging
Web browsing
It's important now that Google have provided a definitive list of the Intents that should be used for performing a given action, that we use them exactly as provided there. The reasoning behind Intents is all about a standard method of communication between apps (i.e. different developers), so it is important for the sake of your app's compatibility to talk in exactly the same language as the one everyone else will be using.
