I'm trying to write a launcher-like application (I'm not planning to release it, it's just for me to use) but I don't seem to find any way to launch the Market.
All of the answers I've found actually perform a search on the Market (using a uri "market://") or even worse they run the Market on a specific app page, while I'm trying to show the main page of the Market, i.e. the page shown when you run it from the launcher.
I tried using just "market://" as a Uri, without query strings, but it doesn't work; I also tried to get exactly the same "signature" of the "start activity command" that appears in the LogCat when I run the Market from the Launcher (by manually editing component, flags and categories), but it still doesn't work.
Is there any way to get it to show the main page?
Thanks in anticipation.
Intent intent = new Intent();
intent.setClassName("com.android.vending", "com.android.vending.AssetBrowserActivity");
startActivity(intent);

I have three existing apps. Now i want to combine all the three into single app.
Say i have three button, when i click button 1 then app 1 should run. And when
button 2 is clicked app 2 should run. Is it possible in android studio? have
have tried searching but nothing helped.
From this SO start application knowing package name. Just use these two lines you can launch any installed application whose package name is known:
Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("com.example.abc");
startActivity( LaunchIntent );
for the unknown package name
PackageManager pm;
pm = getPackageManager();
// get a list of installed apps.
packages = pm.getInstalledApplications(0);
I'm going to preface this by saying I do not have any experience with Android Studio. Hopefully it bears some resemblance with its terribly simplified counterpart App Inventor.
Anywho, I would create an independent main screen (activity?) that has 3 buttons on it and paste the three existing apps' code into other screens in the same app. Each button would open its corresponding screen/app through opening a new activity.
Got the solution. I just converted the three applications to library and imported them into the main app. Now i can call any activity from any of the three app any time as required. While using package manage all the three apps would have to be installed separately. Thank you coder and himty for sparing some time to answer my question. But still i have a problem. I am actually working on watch faces. Even though i can launch any activity, i still can't change the watch face. Tried Wallpaper but we can only open the face picker & cannot set the watch face.
ComponentName unique=new ComponentName(MainActivity.this,BlackOwlBlue.class);
Intent i=new Intent(WallpaperManager.ACTION_CHANGE_LIVE_WALLPAPER)
.putExtra(WallpaperManager.EXTRA_LIVE_WALLPAPER_COMPONENT,unique)
.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
I'm trying to start default android wallpaper chooser. I'm using:
Intent intent = new Intent(Intent.ACTION_SET_WALLPAPER);
startActivity(intent);
This code works but it opens app chooser. I want to open "Wallpapers" directly. My minSdkVersion is set to 16.
By "default" you seem to mean the wallpaper app that came with Android OS, rather than other wallpaper apps that the device may have. You can force Android to launch a particular activity by setting the component in the intent.
Intent intent = new Intent(Intent.ACTION_SET_WALLPAPER);
intent.setComponent(...);
startActivity(intent);
However, this is a risky thing to do. If you run this code on a device that doesn't have the wallpaper app that you've specified, then you will get an ActivityNotFoundException.
Do you really need to launch one particular wallpaper app? A central feature of Android is that you say what you want to do, and it finds the app to do it. I don't know what your goal is, but another function that might be helpful is PackageManager.resolveActivity. You can use it to discover, in code, what app would be launched for a particular intent.

I am new in android and I have develop an application in android but the issue is when i install it on my device it shows me 2 icons one is working and other one says that receipt organizer has been stopped unexpectedly.Kindly let me know how i can get out of this rid ?Is it some kind of code error or problem in the manifest or properties ?Also one more question now my api level is set to 18 if i set it to previous version then the functionality will not get disturbed right ?So let me know if any one can help.
Look at your manifest file. Your manifest file should have only one activity that has the LAUNCHER in the intent filter.
Choose your main activity (which should have this intent filter), and delete the intent filters from the other activity. after that, you should see only one application icon.
I just wanted to "help" my users to give feedback to my app by providing a button to launch Market. Found a working solution here, of course, which does:
Uri uri = Uri.parse("market://details?id=<mypackagename>");
Intent intent = new Intent (Intent.ACTION_VIEW, uri);
startActivity(intent);
Simple as that, thanks!
But: on my first run, I had that on my emulator. Gives an ActivityNotFoundException immediately.
Now, my question: is there a way to find out whether a call to this intent will succeed BEFORE I try it? That way I could hide the button completely to not even give the option.
Thanks for your much appreciated help!
Instead of using this URL, you can use this one:
https://market.android.com/details?id=<mypackagename>
Even if the user doesn't have the Market application, he could go to the Website.
If he has the Market application, he should have a prompt between Internet and Market.
BTW, surround your code with a try catch in case he has nothing ;o)
You can also use this method.
Instead of IMDB, use your market URL: market://details?id=<mypackagename>
The exception was thrown just because there is no Android Market on the emulators. Every Android-powered device has the Android Market, so you shouldn't worry about this exception being thrown on a real device. Hope this helps.
If I want to create custom address book (which overrides my phone's default address book), and if I want it to be used by all applications, what should be my intent-filter? Does Android allow me to do such a thing considering the fact that such a third-party app could potentially be malicious?!
And, if I want to have yet another address book application, I suppose the second app also has same intent-filter, isn't it? How does the framework decide which app to pick if I click on Contacts button when making a call? In other words, how does the framework resolve intents in case,there is a conflict between multiple intent-filters?
You can replace any application on Android platform, even Home. Android documentation explains everything there is to know about Intents and Intent Filters and there is a section called Intent Resolution that answers your question. Intent Resolution section for Intent class has some additional information.
As far as I can tell Android doesn't try to resolve a conflict. It ask the user which application to run and gives them the choice to mark this Activity as the default for this Intent. They give an example about mail app here.
While Mr. Smiljanić is basically correct, there is no Contacts application in Android for you to replace. There is Dialtacts, which is the application supporting the contacts, call log, and dialer. That application cannot be replaced, mostly because the dialer cannot be replaced.
So, while you may be able to override some intent filters and get control on some contacts-related requests, you will be unable to get the contacts portion of Dialtacts overridden, which will confuse users.
