Limiting Android PackageManager to a single choice - android

My application evokes the android PackageManager when a file is chosen and the user is presented with a choice of applications to handle how the file should be dealt with. I want to limit this choice to Bluetooth. Currently Bluetooth comes up as the first option which is fine and this all works. I was wondering if its possible to only present the user with this single option.
case REQUEST_FILE_SELECT:
if (requestCode == REQUEST_FILE_SELECT) {
// Get the Uri of the selected file
Uri uri = data.getData();
Log.d(TAG, "File Uri: " + uri.toString());
// Get the path
String path = null;
try {
path = FileUtils.getPath(this, uri);
} catch (URISyntaxException e) {
e.printStackTrace();
}
Log.d(TAG, "File Path: " + path);
// Get the file instance
File mFile = new File(path);
// Evoke the file chooser
List<Intent> targetedShareIntents = new ArrayList<Intent>();
Intent shareIntent = new Intent(
android.content.Intent.ACTION_SEND);
shareIntent.setType("*/*");
// Evoke the package manager
List<ResolveInfo> resInfo = getPackageManager()
.queryIntentActivities(shareIntent,
PackageManager.GET_ACTIVITIES);
if (!resInfo.isEmpty()) {
for (ResolveInfo resolveInfo : resInfo) {
String packageName = resolveInfo.activityInfo.packageName;
if (packageName.equals("com.android.bluetooth")) {
Intent targetedShareIntent = new Intent(
android.content.Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM,
Uri.fromFile(mFile));
targetedShareIntent.setPackage(packageName);
targetedShareIntents.add(targetedShareIntent);
startActivity(Intent.createChooser(shareIntent,
"Share File"));
}
}
}
}

Solution: find out which apps does the device support for your intent, find the one that is bluetooh, invoke it directly.
This article answers your question:
http://tsicilian.wordpress.com/2012/11/06/bluetooth-data-transfer-with-android/
From the article:
We can see that the BT application is among those handlers. We could of course let the user pick that application from the list and be done with it. But if we feel we should be a tad more user-friendly, we need to go further and start the application ourselves, instead of simply displaying it in a midst of other unnecessary options…But how?
One way to do that would be to use Android’s PackageManager this way:
//list of apps that can handle our intent
PackageManager pm = getPackageManager();
List appsList = pm.queryIntentActivities( intent, 0);
if(appsList.size() > 0 {
// proceed
}
The above PackageManager method returns the list we saw earlier of all activities susceptible to handle our file transfer intent, in the form of a list of ResolveInfo objects that encapsulate information we need:
//select bluetooth
String packageName = null;
String className = null;
boolean found = false;
for(ResolveInfo info: appsList){
packageName = info.activityInfo.packageName;
if( packageName.equals("com.android.bluetooth")){
className = info.activityInfo.name;
found = true;
break;// found
}
}
if(! found){
Toast.makeText(this, R.string.blu_notfound_inlist,
Toast.LENGTH_SHORT).show();
// exit
}
We now have the necessary information to start BT ourselves:
//set our intent to launch Bluetooth
intent.setClassName(packageName, className);
startActivity(intent);
What we did was to use the package and its corresponding class retrieved earlier. Since we are a curious bunch, we may wonder what the class name for the “com.android.bluetooth” package is. This is what we would get if we were to print it out: com.broadcom.bt.app.opp.OppLauncherActivity. OPP stands for Object Push Profile, and is the Android component allowing to wirelessly share files.

Android Filter Intent Chooser

I would like to filter the list you see below. Only file-explorer should be choosable.
intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory() + "/Android/data/" + getContext().getPackageName() + "/Files");
intent.setDataAndType(uri, "*/*");
startActivity(Intent.createChooser(intent, getString(R.string.openFolder)));
EDIT:
This is not possible. There is no magic Intent that always only opens some magic app category.
First, anyone can write any app to respond to any desired implicit Intent.
Second, there is no universal definition of "file explorer". What you think a "file explorer" is may differ from what other developers think a "file explorer" is, which in turn may differ from what users think a "file explorer" is. A user's device may not even have a "file explorer", from anyone's definition.
Add this in your Intent, it would open a ES File Explorer
Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("*/*");
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(filePath)));
intent.setPackage("com.estrongs.android.pop");
startActivity(shareIntent);
You can call the below function
type is the package name of file-explorer
like if you want to share data to Twitter call it like initShareIntent("com.twitter.android");
private void initShareIntent(String type) {
boolean found = false;
Intent share = new Intent(android.content.Intent.ACTION_SEND);
share.setType("image/jpeg");
// gets the list of intents that can be loaded.
List<ResolveInfo> resInfo = getActivity().getPackageManager().queryIntentActivities(share, 0);
if (!resInfo.isEmpty()) {
for (ResolveInfo info : resInfo) {
if (info.activityInfo.packageName.toLowerCase().contains(type) ||
info.activityInfo.name.toLowerCase().contains(type)) {
//Share Data here
share.setPackage(info.activityInfo.packageName);
found = true;
break;
}
}
if (!found) {
Toast.makeText(getActivity(), share_type + " not found in Device", Toast.LENGTH_SHORT).show();
return;
}
startActivity(Intent.createChooser(share, "Select"));
}
}
It will only open the particular app to share data. Try this and let me know if it helped you
Make sure that the directory exists then try this :
Intent fileManagers = new Intent();
fileManagers.setAction(Intent.ACTION_GET_CONTENT);
File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
.getAbsolutePath());
Uri uri = Uri.fromFile(dir);
fileManagers.setDataAndType(uri, "file/*");
startActivity(Intent.createChooser(fileManagers, null));

how to find my android application's storing path of apk file

I want to make an application that could send itself (apk file) by bluetooth. but i have trouble with finding the apk file path. i tried this code:
final PackageManager pm = this.getPackageManager();
List<PackageInfo> packages = pm.getInstalledPackages(PackageManager.GET_META_DATA);
String st = null;
for (PackageInfo packageInfo : packages) {
if(packageInfo.packageName.contains("testbutton"))
st=packageInfo.packageName;
}
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/*");
String uri = "/data/app/";
uri+=st;
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(uri)));
startActivity(intent);
but st returns null value.
please help me with this. thanks in advance
finally i'd found the right answer that works in this purpose, thanks to #Kanak for her help :)
PackageManager pm = getPackageManager();
String uri = null;
for (ApplicationInfo app : pm.getInstalledApplications(0)) {
if(!((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) == 1))
if(!((app.flags & ApplicationInfo.FLAG_SYSTEM) == 1)){
uri=app.sourceDir;
if(uri.contains("com.example.test"))
break;
}
}
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(uri)));
startActivity(intent);
There is no need to iteration. Getting the application itself APK file uri is as easy as this:
String appUri = getApplicationInfo().publicSourceDir;
Also note that doc says this about publicSourceDir:
Full path to the publicly available parts of sourceDir,
including resources and manifest. This may be different from
sourceDir if an application is forward locked.
And also note that to send an APK file, you need to set the type to application/vnd.android.package-archive instead of image/*
So the complete snippet would be:
String appUri = getApplicationInfo().publicSourceDir;
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("application/vnd.android.package-archive");
sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(appUri)));
startActivity(Intent.createChooser(sharingIntent, "Share via"));

how to send media files via bluetooth in android

I have a requirement. I need to build an app, which uses Bluetooth to send media files like songs, images etc to another device. I have no knowledge about how to do this. Can anyone assist from scratch to make me get a rough idea about how getting this done. Sample code would be very helpful.
Thanks.
I think you should read this document once .
In this example they are sending PDF file form SD Card Path but i think you can also send
media file like audio and video as same.
see this : Bluetooth file transfer Android
private void envio() {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");
File archivo=new File(_path);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(archivo) );
///////////////////pakage manager
PackageManager pm = getPackageManager();
List<ResolveInfo> appsList = pm.queryIntentActivities( intent, 1);
if(appsList.size() > 0) {
//Toast.makeText(this,"su telefono no cuenta con aplicacion de intercambio de datos",Toast.LENGTH_LONG).show();
}
//selleccionar la aplicacion de bluetooth
String packageName = null;
String className = null;
boolean found = false;
// BluetoothAdapter.checkBluetoothAddress("");
for(ResolveInfo info: appsList){
packageName = info.activityInfo.packageName;
if( packageName.equals("com.android.bluetooth")){
className = info.activityInfo.name;
found = true;
break;// found
}
}
if(! found){
Toast.makeText(this,"...",
Toast.LENGTH_SHORT).show();
// exit
}
intent.setClassName(packageName, className);
startActivity(intent);
}

How to filter specific apps for ACTION_SEND intent (and set a different text for each app)

How can you filter out specific apps when using the ACTION_SEND intent? This question has been asked in various ways, but I haven't been able to gather a solution based on the answers given. Hopefully someone can help. I would like to provide the ability to share within an app. Following Android Dev Alexander Lucas' advice, I'd prefer to do it using intents and not using the Facebook/Twitter APIs.
Sharing using the ACTION_SEND intent is great, but the problem is (1) I don't want every sharing option there, I'd rather limit it to FB, Twitter, and Email, and (2) I don't want to share the same thing to each sharing app. For example, in my twitter share I'm going to include some mentions and hashtags limited it to 140 chars or less, while the facebook share is going to include a link and a feature image.
Is it possible to limit the options for ACTION_SEND (share) intent? I've seen something about using PackageManager and queryIntentActivities, but haven't been able to figure out the connection between the PackageManager and the ACTION_SEND intent.
OR
Rather than filter the sharing apps, my problem could also be solved if I could use the ACTION_SEND intent to go directly to facebook or twitter rather than popping up the dialog. If that were the case then I could create my own dialog and when they click "Facebook" create a Facebook-specific intent and just send them all the way to Facebook. Same with Twitter.
OR is it not possible? Are the Facebook and Twitter APIs the only way?
My spec called for the user to be able to choose email, twitter, facebook, or SMS, with custom text for each one. Here is how I accomplished that:
public void onShareClick(View v) {
Resources resources = getResources();
Intent emailIntent = new Intent();
emailIntent.setAction(Intent.ACTION_SEND);
// Native email client doesn't currently support HTML, but it doesn't hurt to try in case they fix it
emailIntent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(resources.getString(R.string.share_email_native)));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.share_email_subject));
emailIntent.setType("message/rfc822");
PackageManager pm = getPackageManager();
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
Intent openInChooser = Intent.createChooser(emailIntent, resources.getString(R.string.share_chooser_text));
List<ResolveInfo> resInfo = pm.queryIntentActivities(sendIntent, 0);
List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();
for (int i = 0; i < resInfo.size(); i++) {
// Extract the label, append it, and repackage it in a LabeledIntent
ResolveInfo ri = resInfo.get(i);
String packageName = ri.activityInfo.packageName;
if(packageName.contains("android.email")) {
emailIntent.setPackage(packageName);
} else if(packageName.contains("twitter") || packageName.contains("facebook") || packageName.contains("mms") || packageName.contains("android.gm")) {
Intent intent = new Intent();
intent.setComponent(new ComponentName(packageName, ri.activityInfo.name));
intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");
if(packageName.contains("twitter")) {
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_twitter));
} else if(packageName.contains("facebook")) {
// Warning: Facebook IGNORES our text. They say "These fields are intended for users to express themselves. Pre-filling these fields erodes the authenticity of the user voice."
// One workaround is to use the Facebook SDK to post, but that doesn't allow the user to choose how they want to share. We can also make a custom landing page, and the link
// will show the <meta content ="..."> text from that page with our link in Facebook.
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_facebook));
} else if(packageName.contains("mms")) {
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_sms));
} else if(packageName.contains("android.gm")) { // If Gmail shows up twice, try removing this else-if clause and the reference to "android.gm" above
intent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(resources.getString(R.string.share_email_gmail)));
intent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.share_email_subject));
intent.setType("message/rfc822");
}
intentList.add(new LabeledIntent(intent, packageName, ri.loadLabel(pm), ri.icon));
}
}
// convert intentList to array
LabeledIntent[] extraIntents = intentList.toArray( new LabeledIntent[ intentList.size() ]);
openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
startActivity(openInChooser);
}
I found bits of how to do this in various places, but I haven't seen all of it in one place anywhere else.
Note that this method also hides all the silly options that I don't want, like sharing over wifi and bluetooth.
Edit:
In a comment, I was asked to explain what this code is doing. Basically, it's creating an ACTION_SEND intent for the native email client ONLY, then tacking other intents onto the chooser. Making the original intent email-specific gets rid of all the extra junk like wifi and bluetooth, then I grab the other intents I want from a generic ACTION_SEND of type plain-text, and tack them on before showing the chooser.
When I grab the additional intents, I set custom text for each one.
Edit2: It's been awhile since I posted this, and things have changed a bit. If you are seeing gmail twice in the list of options, try removing the special handling for "android.gm" as suggested in a comment by #h_k below.
Since this one answer is the source of nearly all my stackoverflow reputation points, I have to at least try to keep it up to date.
If you want a customized option then you should not rely on the default dialog provided by android for this action.
What you need to do instead is roll out your own. You will need to query the PackageManager on which packages handle the action you require and then based on the reply, you apply filtering and customized text.
Specifically, take a look at the method queryIntentActivities of the PackageManager class. You build the intent that would launch the default dialog (the ACTION_SEND intent), pass that to this method and you will receive a list of objects that contain info on the activities that can handle that intent. Using that, you can choose the ones you want.
Once you build your list of packages you want to present, you need to build your own list dialog (preferably an activity with the dialog theme) which will display that list.
One thing to note though is that it's very hard to make that custom dialog look like the default one. The problem is that the theme used in that dialog is an internal theme and cannot be used by your application. You can either try to make it as similar to the native one as you want or go for a completely custom look (many apps do that like the gallery app etc)
Found a solution that works for me looking here (see the third comment on the first answer). This code looks for a valid twitter client and uses it to post the tweet. Note: It does not give you an Intent with the various Twitter clients and allow you to choose.
Share using twitter:
Intent shareIntent = findTwitterClient();
shareIntent.putExtra(Intent.EXTRA_TEXT, "test");
startActivity(Intent.createChooser(shareIntent, "Share"));
Calling this method:
public Intent findTwitterClient() {
final String[] twitterApps = {
// package // name - nb installs (thousands)
"com.twitter.android", // official - 10 000
"com.twidroid", // twidroid - 5 000
"com.handmark.tweetcaster", // Tweecaster - 5 000
"com.thedeck.android" }; // TweetDeck - 5 000 };
Intent tweetIntent = new Intent();
tweetIntent.setType("text/plain");
final PackageManager packageManager = getPackageManager();
List<ResolveInfo> list = packageManager.queryIntentActivities(
tweetIntent, PackageManager.MATCH_DEFAULT_ONLY);
for (int i = 0; i < twitterApps.length; i++) {
for (ResolveInfo resolveInfo : list) {
String p = resolveInfo.activityInfo.packageName;
if (p != null && p.startsWith(twitterApps[i])) {
tweetIntent.setPackage(p);
return tweetIntent;
}
}
}
return null;
}
Facebook will be similar using "com.facebook.katana", although you still can't set the message text (deprecated July 2011).

Thanks to #dacoinminster. I make some modifications to his answer including package names of the popular apps and sorting of those apps.
List<Intent> targetShareIntents = new ArrayList<Intent>();
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
PackageManager pm = getActivity().getPackageManager();
List<ResolveInfo> resInfos = pm.queryIntentActivities(shareIntent, 0);
if (!resInfos.isEmpty()) {
System.out.println("Have package");
for (ResolveInfo resInfo : resInfos) {
String packageName = resInfo.activityInfo.packageName;
Log.i("Package Name", packageName);
if (packageName.contains("com.twitter.android") || packageName.contains("com.facebook.katana")
|| packageName.contains("com.whatsapp") || packageName.contains("com.google.android.apps.plus")
|| packageName.contains("com.google.android.talk") || packageName.contains("com.slack")
|| packageName.contains("com.google.android.gm") || packageName.contains("com.facebook.orca")
|| packageName.contains("com.yahoo.mobile") || packageName.contains("com.skype.raider")
|| packageName.contains("com.android.mms")|| packageName.contains("com.linkedin.android")
|| packageName.contains("com.google.android.apps.messaging")) {
Intent intent = new Intent();
intent.setComponent(new ComponentName(packageName, resInfo.activityInfo.name));
intent.putExtra("AppName", resInfo.loadLabel(pm).toString());
intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "https://website.com/");
intent.putExtra(Intent.EXTRA_SUBJECT, getString(R.string.share_text));
intent.setPackage(packageName);
targetShareIntents.add(intent);
}
}
if (!targetShareIntents.isEmpty()) {
Collections.sort(targetShareIntents, new Comparator<Intent>() {
#Override
public int compare(Intent o1, Intent o2) {
return o1.getStringExtra("AppName").compareTo(o2.getStringExtra("AppName"));
}
});
Intent chooserIntent = Intent.createChooser(targetShareIntents.remove(0), "Select app to share");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetShareIntents.toArray(new Parcelable[]{}));
startActivity(chooserIntent);
} else {
Toast.makeText(getActivity(), "No app to share.", Toast.LENGTH_LONG).show();
}
}
You can try the code below, it works perfectly.
Here we share to some specific apps, that are Facebook, Messenger, Twitter, Google Plus and Gmail.
public void shareIntentSpecificApps() {
List<Intent> intentShareList = new ArrayList<Intent>();
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
List<ResolveInfo> resolveInfoList = getPackageManager().queryIntentActivities(shareIntent, 0);
for (ResolveInfo resInfo : resolveInfoList) {
String packageName = resInfo.activityInfo.packageName;
String name = resInfo.activityInfo.name;
Log.d(TAG, "Package Name : " + packageName);
Log.d(TAG, "Name : " + name);
if (packageName.contains("com.facebook") ||
packageName.contains("com.twitter.android") ||
packageName.contains("com.google.android.apps.plus") ||
packageName.contains("com.google.android.gm")) {
if (name.contains("com.twitter.android.DMActivity")) {
continue;
}
Intent intent = new Intent();
intent.setComponent(new ComponentName(packageName, name));
intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, "Your Subject");
intent.putExtra(Intent.EXTRA_TEXT, "Your Content");
intentShareList.add(intent);
}
}
if (intentShareList.isEmpty()) {
Toast.makeText(MainActivity.this, "No apps to share !", Toast.LENGTH_SHORT).show();
} else {
Intent chooserIntent = Intent.createChooser(intentShareList.remove(0), "Share via");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentShareList.toArray(new Parcelable[]{}));
startActivity(chooserIntent);
}
}
This solution shows a list of applications in a ListView dialog that resembles the chooser:
It is up to you to:
obtain the list of relevant application packages
given a package name, invoke the relevant intent
The adapter class:
import java.util.List;
import android.content.Context;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.graphics.drawable.Drawable;
import android.util.TypedValue;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
public class ChooserArrayAdapter extends ArrayAdapter<String> {
PackageManager mPm;
int mTextViewResourceId;
List<String> mPackages;
public ChooserArrayAdapter(Context context, int resource, int textViewResourceId, List<String> packages) {
super(context, resource, textViewResourceId, packages);
mPm = context.getPackageManager();
mTextViewResourceId = textViewResourceId;
mPackages = packages;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
String pkg = mPackages.get(position);
View view = super.getView(position, convertView, parent);
try {
ApplicationInfo ai = mPm.getApplicationInfo(pkg, 0);
CharSequence appName = mPm.getApplicationLabel(ai);
Drawable appIcon = mPm.getApplicationIcon(pkg);
TextView textView = (TextView) view.findViewById(mTextViewResourceId);
textView.setText(appName);
textView.setCompoundDrawablesWithIntrinsicBounds(appIcon, null, null, null);
textView.setCompoundDrawablePadding((int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 12, getContext().getResources().getDisplayMetrics()));
} catch (NameNotFoundException e) {
e.printStackTrace();
}
return view;
}
}
and its usage:
void doXxxButton() {
final List<String> packages = ...;
if (packages.size() > 1) {
ArrayAdapter<String> adapter = new ChooserArrayAdapter(MyActivity.this, android.R.layout.select_dialog_item, android.R.id.text1, packages);
new AlertDialog.Builder(MyActivity.this)
.setTitle(R.string.app_list_title)
.setAdapter(adapter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item ) {
invokeApplication(packages.get(item));
}
})
.show();
} else if (packages.size() == 1) {
invokeApplication(packages.get(0));
}
}
void invokeApplication(String packageName) {
// given a package name, create an intent and fill it with data
...
startActivityForResult(intent, rq);
}
The cleanest way is to copy the following classes: ShareActionProvider, ActivityChooserView, ActivityChooserModel. Add the ability to filter the intents in the ActivityChooserModel, and the appropriate support methods in the ShareActionProvider. I created the necessary classes, you can copy them into your project (https://gist.github.com/saulpower/10557956). This not only adds the ability to filter the apps you would like to share with (if you know the package name), but also to turn off history.
private final String[] INTENT_FILTER = new String[] {
"com.twitter.android",
"com.facebook.katana"
};
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.journal_entry_menu, menu);
// Set up ShareActionProvider's default share intent
MenuItem shareItem = menu.findItem(R.id.action_share);
if (shareItem instanceof SupportMenuItem) {
mShareActionProvider = new ShareActionProvider(this);
mShareActionProvider.setShareIntent(ShareUtils.share(mJournalEntry));
mShareActionProvider.setIntentFilter(Arrays.asList(INTENT_FILTER));
mShareActionProvider.setShowHistory(false);
((SupportMenuItem) shareItem).setSupportActionProvider(mShareActionProvider);
}
return super.onCreateOptionsMenu(menu);
}
I have improved #dacoinminster answer and this is the result with an example to share your app:
// Intents with SEND action
PackageManager packageManager = context.getPackageManager();
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
List<ResolveInfo> resolveInfoList = packageManager.queryIntentActivities(sendIntent, 0);
List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();
Resources resources = context.getResources();
for (int j = 0; j < resolveInfoList.size(); j++) {
ResolveInfo resolveInfo = resolveInfoList.get(j);
String packageName = resolveInfo.activityInfo.packageName;
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setComponent(new ComponentName(packageName,
resolveInfo.activityInfo.name));
intent.setType("text/plain");
if (packageName.contains("twitter")) {
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.twitter) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
} else {
// skip android mail and gmail to avoid adding to the list twice
if (packageName.contains("android.email") || packageName.contains("android.gm")) {
continue;
}
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.largeTextForFacebookWhatsapp) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
}
intentList.add(new LabeledIntent(intent, packageName, resolveInfo.loadLabel(packageManager), resolveInfo.icon));
}
Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.subjectForMailApps));
emailIntent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.largeTextForMailApps) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
context.startActivity(Intent.createChooser(emailIntent, resources.getString(R.string.compartirEn)).putExtra(Intent.EXTRA_INITIAL_INTENTS, intentList.toArray(new LabeledIntent[intentList.size()])));
I had same problem and this accepted solution didn't helped me, if someone has same problem you can use my code snippet:
// example of filtering and sharing multiple images with texts
// remove facebook from sharing intents
private void shareFilter(){
String share = getShareTexts();
ArrayList<Uri> uris = getImageUris();
List<Intent> targets = new ArrayList<>();
Intent template = new Intent(Intent.ACTION_SEND_MULTIPLE);
template.setType("image/*");
List<ResolveInfo> candidates = getActivity().getPackageManager().
queryIntentActivities(template, 0);
// remove facebook which has a broken share intent
for (ResolveInfo candidate : candidates) {
String packageName = candidate.activityInfo.packageName;
if (!packageName.equals("com.facebook.katana")) {
Intent target = new Intent(Intent.ACTION_SEND_MULTIPLE);
target.setType("image/*");
target.putParcelableArrayListExtra(Intent.EXTRA_STREAM,uris);
target.putExtra(Intent.EXTRA_TEXT, share);
target.setPackage(packageName);
targets.add(target);
}
}
Intent chooser = Intent.createChooser(targets.remove(0), "Share Via");
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, targets.toArray(new Parcelable[targets.size()]));
startActivity(chooser);
}
Intent emailIntent = new Intent(Intent.ACTION_SENDTO,
Uri.fromParts("mailto", "android#gmail.com", null));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, text);
startActivity(Intent.createChooser(emailIntent, "Send email..."));
So simple and concise. Thanks to the Open source developer, cketti for sharing this solution:
String mailto = "mailto:bob#example.org" +
"?cc=" + "alice#example.com" +
"&subject=" + Uri.encode(subject) +
"&body=" + Uri.encode(bodyText);
Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
emailIntent.setData(Uri.parse(mailto));
try {
startActivity(emailIntent);
} catch (ActivityNotFoundException e) {
//TODO: Handle case where no email app is available
}
And this is the link to his/her gist.

Get Preferred/Default app on Android

I am trying to get the default/preferred application for a given Intent. For example, when the user installs a second web browser, then attempts to open a URL, he or she will get a dialog like this:
If the user then selects the Use by default for this action option, then the dialog box no longer opens when a URL is pressed.
I am working on an application that should be aware of what this default or preferred app/action is. How do I do this? I am currently using the code below, but getPreferredPackage doesn't return anything:
Intent i = (new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.google.com"));
PackageManager pm = context.getPackageManager();
final List<ResolveInfo> list = pm.queryIntentActivities(i, 0);
IntentFilter ifilter = new IntentFilter(i.getAction());
if (i.getCategories() != null) {
for(String category : i.getCategories()) {
ifilter.addCategory(category);
}
}
List<IntentFilter> filters = new ArrayList<IntentFilter>();
filters.add(ifilter);
List<ComponentName> preferredActivities = new ArrayList<ComponentName>();
pm.getPreferredActivities(filters, preferredActivities, null);
for (ComponentName activity : preferredActivities) {
for (ResolveInfo rinfo : list) {
if (rinfo.activityInfo.applicationInfo.packageName.equals(activity.getPackageName())) {
try {
final PackageInfo pi = pm.getPackageInfo(activity.getPackageName(), 0);
Toast.makeText(context, pm.getApplicationLabel(pi.applicationInfo), Toast.LENGTH_SHORT).show();
}
} catch (NameNotFoundException e) {
e.printStackTrace();
}
}
}
What am I doing wrong? Is this even the right approach?
Well, the solution turned out to be much simpler than I made it (although this is very poorly documented). The following code is my solution:
Intent i = (new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.google.com"));
PackageManager pm = context.getPackageManager();
final ResolveInfo mInfo = pm.resolveActivity(i, 0);
Toast.makeText(context, pm.getApplicationLabel(mInfo.activityInfo.applicationInfo), Toast.LENGTH_LONG).show();
The method launchUrlInDefaultBrowser below launches a URL without displaying any selection query for the user. First, it tries to find the user's default browser app and launch the URL with it. Second, if there was no default app, it lists all the capable activities for launching the URL and picks up the first one. In case an activity was launched, the method returns true; otherwise, false.
boolean launchUrlInDefaultBrowser(Context context, String url) {
final Intent browserIntent = new Intent(Intent.ACTION_VIEW);
browserIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
browserIntent.setData(Uri.parse(url));
// 1: Try to find the default browser and launch the URL with it
final ResolveInfo defaultResolution = context.getPackageManager().resolveActivity(browserIntent, PackageManager.MATCH_DEFAULT_ONLY);
if (defaultResolution != null) {
final ActivityInfo activity = defaultResolution.activityInfo;
if (!activity.name.equals("com.android.internal.app.ResolverActivity")) {
browserIntent.setClassName(activity.applicationInfo.packageName, activity.name);
context.startActivity(launchIntent);
return true;
}
}
// 2: Try to find anything that we can launch the URL with. Pick up the first one that can.
final List<ResolveInfo> resolveInfoList = context.getPackageManager().queryIntentActivities(browserIntent, PackageManager.MATCH_DEFAULT_ONLY);
if (!resolveInfoList.isEmpty()) {
browserIntent.setClassName(resolveInfoList.get(0).activityInfo.packageName, resolveInfoList.get(0).activityInfo.name);
context.startActivity(browserIntent);
return true;
}
return false;
}
Beware, the OEMs may have their own ResolverActivity implementation. E.g. Huawei has com.huawei.android.internal.app.HwResolverActivity.
In Kitkat AOSP, getPreferredPackages() always returns empty list. Source code as below
public List<PackageInfo> getPreferredPackages(int flags) {
return new ArrayList<PackageInfo>();
}
