Im developing an application where in I have 2 text views and a button.
when I click the button, it should open default system contacts application and upon selecting a contact, it should display the name and number in the text fields respectively.
Now I have implemented ContactsContract and getContentResolver. But, I have seen other apps having this feature, which is quite easy because you need not create a list view and stuffs.
Now how do I start? how do I invoke default contact app and retrieve data from it.
I don't know the details about your problem, but I am pretty sure that you need to use an Implicit Intent (because the Contacts app may be different on different devices). Hopefully this page will help.
You may need to start by using this code:
Intent i = new Intent(); // Declare intent
// Start the intent
startActivity(i);
You may want to use ACTION_GET_CONTENT.
Thanks for the replies. I found out that this is what i need.
Intent localIntent = new Intent("android.intent.action.PICK",ContactsContract.Contacts.CONTENT_URI);

I am looking for a way to create shortcuts from other apps.
Like launchs can query the apps that allow to create shortcuts and create them save them in thier program.
My API version is between M(21) to N7.1(25).
Even just a link or name of API it's fine. I just couldn't find it at all. All I found is about the new shortcut in android N.
Thx for ur time.
I found the way to do it. Since i don't see much info for this. I hope my share can help whoever is also looking for the answer.
So there will be 3 steps:
Get apps that can create shortcuts
Send Intent to the app that you want to create shortcut from
Get shortcut data in Activity.onActivityResult
1.
Since I just need to create shortcuts from certain apps. I skipped step one. But I guess using queryIntentActivities(...) or some other functions in PackageManager can get you the list.
Intent intent = new Intent("android.intent.action.CREATE_SHORTCUT");
PackageManager.queryIntentActitvies(intent,0);
2. Send intent to the app to create a shortcut.
Intent intent = new Intent("android.intent.action.CREATE_SHORTCUT");
intent.setComponent(...);
startActivityForResult(intent, requestCode);
3. Get data of shortcut:
Shortcut intent
Intent shortcutIntent = activityResultIntent.getParcelableExtra(Intent.EXTRA_SHORTCUT_INTENT);
Shortcut name
String shortcutName = intent.getStringExtra(Intent.EXTRA_SHORTCUT_NAME);
Shortcut icon
Bitmap shortcutIcon = intent.getParcelableExtra(Intent.EXTRA_SHORTCUT_ICON);
How to call Android contacts app inside an activity. The activity may contains other controls like button, but somewhere (inside the same activity) it displays the contacts app so that i can perform certain actions like add, view, edit etc. By actions, i mean the actions that Android contacts app provides. Following code calls android contacts app as an intent:
Intent i = new Intent();
i.setComponent(new ComponentName("com.android.contacts", "com.android.contacts.DialtactsContactsEntryActivity"));
i.setAction("android.intent.action.MAIN");
i.addCategory("android.intent.category.LAUNCHER");
i.addCategory("android.intent.category.DEFAULT");
startActivity(i);
It does not work like this. You can not add another app inside your app. You can use Content Providers for app functionality with contacts (e.g. to add/edit/remove contacts progmatically). or use intents with action View, Edit or Pick to handle the contact inside the contact application itself.
I need to allow user to draw/sketch/paint something. There are already many apps(like Skitch, I will use this as an example) that accomplish this task. So I don't want to re-invent the wheel.
In Android, theoretically, we can launch other activity by intent. This is sort of like "pipe" in Unix.
The problem is, I don't know how to get the information for launching Skitch.
To integrate Skitch in my app, I need to know the Action it supports, the returning intent (if any) when it finishes.
I installed Skitch, photoshop, and lots of other touch drawing apps in my device, but this code doesn't work :
Uri data = Uri.fromFile(file);
Intent i = new Intent(Intent.ACTION_EDIT);
i.setData(data);
i.setType("image/*");
startActivityForResult(i, ACTIVITY_DRAW);
I can launch Skitch from my app in the following way: but obviously I can't get any returned result this way(code from here).
Intent i = new Intent(Intent.ACTION_MAIN);
PackageManager manager = getPackageManager();
i = manager.getLaunchIntentForPackage("com.evernote.skitch");
i.addCategory(Intent.CATEGORY_LAUNCHER);
startActivity(i);
My question: Is there a standard way to find information for launching a third party app?
Is this site the only way to share/get such information?
Or if you have any suggestions for my problem, please help me.
Thank you!
As you might already know how to call another application Activity from your app ..this way Mentioned Here.
Intent intent = new Intent(Intent.ACTION_RUN);
intent.setComponent(new ComponentName("<packet name>", "<class name>"));
List list = packageManager.queryIntentActivities(intent, packageManager.COMPONENT_ENABLED_STATE_DEFAULT);
if(list.size() > 0)
{
Log.i("Log", "Have application" + list.size());
startActivity(intent);
}
else
{
Log.i("Log", "None application");
}
All your require is Mainly Two Things to call any Activity
1) Package Name of that Activity
2) Activity Class Name
These two informations only can be available if they are opensource or made free to use .. like Zxing,Google Maps Application.
There is another way to start an application activity like,
Intent intent = new Intent();
intent.setAction(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" + numberField.getText())); // set the Uri
startActivity(intent);
For this way to use need to know the correct Action for the Activity you want to call and the Correct parameter to pass with.
And again,These information only can be available if they are opensource or made free to use .. like Facebook and Gmail apps to share and post messages.
So If you are searching for anything like which can tell you what you will need to pass to call any specific comercial apps in your device, you wont find it directly.
It's an old question but perhaps it could help somebody to know that Sony's AppXplore application (free) shows the package and name of the activities of every app installed on your device, so you can eventually use them to do explicit Intents.
My boss asked me to prove that my application behaves properly when summoned by another application (dunno why he asked that).
So I have two apps here, one launches a second one. How I launch the specific app I want? Using Intent launch seemly any generic app that reaches a certain goal, not the app I really want.
Give this a try.
Intent secondIntent = new Intent();
secondIntent.setAction(Intent.ACTION_MAIN);
secondIntent.setClassName("com.example", "com.example.YourSecondApp");
startActivity(secondIntent);
I should point out that com.example should be the package of your second application (the one you want to call) and com.example.YourSecondapp is the class name where you have your onCreate() method.
Intent secondApp = new Intent("com.test.SecondApp");
startActivity(secondApp);
Check out for more examples

Create one Intent using the following code
Explicit Intent
When you know the particular component(activity/service) to be loaded
Intent intent = new Intent();
intent.setClass("className/package name");
start<Activity/Service>(intent);
Imlicit Intent
When we do not have the idea which class to load and we know the Action to be perform by the launched application we can go with this intent.
Action needs to set, and the Android run time fallows the intent Resolution technique and list out(one or more components) the components to perform the action. from the list out components (if more than one), user will get the chance to launch his chosen application
I would like to launch an app the user selects from within my application. However, I'm not sure how I'd go about doing this. I've tried this:
Intent intent = new Intent();
intent.setAction(Contacts.Intents.SHOW_OR_CREATE_CONTACT);
startActivity(intent);
But this seems to throw an error and force close my application. I also tried adding:
<action android:name="Contacts.Intents.SHOW_OR_CREATE_CONTACT"/>
in the AndroidManifest file, but to no avail.
A look at Logcat shows that it's an "IOexception - no such file or directory". A couple of questions arise from this. I read through the Android docs and noticed that the Contact.Intents class is deprecated. However, it's successor, ContactContracts is aimed at API level 5 whereas I'm targeting API level 3. Could this be the problem? Also, I've hardcoded this application into the code. Is there a way to retrieve the intents of any application the user selects so that they can be launched?
You need to pass extra information into the intent to tell Android what you want to show or create. Otherwise Android doesn't know what activity to start and (presumably in your case) throws an ActivityNotFoundException.
For a contact, you use the generic Intent.ACTION_INSERT_OR_EDIT then use the MIME type of an individual contact (Contacts.People.CONTENT_ITEM_TYPE).
For example:
Intent intent = new Intent(Intent.ACTION_INSERT_OR_EDIT);
intent.setType(People.CONTENT_ITEM_TYPE);
intent.putExtra(Contacts.Intents.Insert.PHONE, "+1234567890");
intent.putExtra(Contacts.Intents.Insert.PHONE_TYPE, Contacts.PhonesColumns.TYPE_MOBILE);
That will bring up the contacts app, prompting you to select an existing contact to add the phone number to, or to create a new contact.
You don't need to add anything special to your manifest to start external activities. Only if you were to directly manipulate the contacts ContentProvider would you need to add the appropriate CONTACT permissions to your manifest.
I use this code for that purpose:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.settings", "com.android.settings.Settings");
startActivity(intent);
This will launch the Settings app, you can use these also:
intent.setClassName("com.android.music", "com.android.music.MediaPlaybackActivityStarter");
intent.setClassName("com.android.contacts", "com.android.contacts.DialtactsContactsEntryActivity");
intent.setClassName("com.android.contacts", "com.android.contacts.DialtactsActivity");
The first starts the default music app, the second the contacts, and the third the dialer.
Hope this helps.
You need to pass in valid arguments to the apps you start. A lot of apps expect the data URI and / or certain extras to be valid.
Please try the following code:
Intent intent = new Intent(Contacts.Intents.SHOW_OR_CREATE_CONTACT);
this.startActivity(intent);
(sorry if there is something wrong on the syntax, I dont have android in this computer)
And remove the action from the manifest. that is not needed.
The action method is used for something else.
For more info, please look at the android site: http://developer.android.com/reference/android/content/Intent.html

The activity you are calling should appear not only in the Manifest for its own package, but in the Manifest for the CALLING package, too.
