Android :: Cannot Use Explicit Intents To Call Another Application?

Aug 29, 2010

Was trying to call another application using an *explicit* intent, but am finding it does not seem possible. I do not wish to use implicit intents. To test it out, try calling the YouTube main activity.

Intent i = new Intent(); ComponentName cn = new ComponentName("com.google.android.youtube","com.google.android.youtube.Home­Activity.class"); i.setComponent(cn); startActivity(i);

I get this error:

08-29 00:54:26.598: ERROR/AndroidRuntime(7332): Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.google.android.youtube/ com.google.android.youtube.HomeActivity.class}; have you declared this activity in your AndroidManifest.xml? Does anyone know whether this is possible? (using explicit intents to call another application)

Android :: ANDROID Intents Problem Launching Application

Jul 5, 2010

My problem is thus; I am new to programming on the ANDROID platform and have a 'working' application that piggy-backs on the API-Docs example. I wish it to launch three tabs one containing a list of reports, one a form to file a report and the last to show the geo-located reports. It doesn't appear as a separate application, it instead appears as a list to be launched by the API-Docs example.

Below is my manifest code...

Android :: Unit Testing SQLiteDatabase Code - How To Instantiate A DB Instance Outside The Emulator

Feb 22, 2010

I need to run unit tests for code that references SQLiteDatabase for my Android code; however all my attempts to instantiate this object outside the emulator (on my desktop machine) have failed. JDBC on Android is not being recommended on the Net, hence it's out of the question (I could have provided mock objects very easily that way).

Android :: How Different Do Broadcast Intents Need To Be?

Oct 30, 2010

I have an IntentService that broadcasts an Intent each time if finishes some work. Each broadcast Intent is identical except that it contains a Bundle with some result information from the IntentService. Evidently, having different data in the Bundle is not enough for Android to think it's a different Intent. If the IntentService broadcasts two of these Intents back-to-back, the second one is dropped as a duplicate.

I know I've read about this behavior in this forum in the past but I can't find in the documentation where this duplicate elimination logic is described in detail. Mostly, I just want to differentiate the Intents enough that they are not considered duplicates. Any pointers would be appreciated.

Android :: Tabs And Intents

Aug 15, 2010

I have a auto-complete textbox in which the user makes a selection. From here I want to load a tabbed layout which is based on the user selection. The problem is I cant figure out a clean way to pass that selection to each of the tabs. At the moment I can pass an intent to the 'tabhost' activity and then pass to each child activity explicitly, however this just seems like messy iterative code to me! So basically how can I pass my intent data bundles to the tabs activities cleanly & efficiently! Psuedo code is also very welcome.

Android :: Intents Alarmmanager

Aug 7, 2010

I am trying to create intents that will be set using alarmmanager. Currently, I can do this with one intent, add extra data to it (strings, but i send them as one string with a seperator), and everything works fine and goes off at the correct time. However, when I try to send multiple intents like this, they are overwritten and only one goes off at the correct time. How can i structure my intents so that they appear different to the alarmmanager (i think they are getting deleted when filterIntent() is run).

long story short- putExtra() makes all the intents look the same still... how can i make them look different so they wont get deleted (and keep track of them in case i want to delete a specific one)

Android :: Passing Values With Intents

Nov 17, 2010

I have searched and searched and I just can't get this code to work. I have a main.xml layout and a setting.xml. I have some values I would like the Settings.class to change in my main apps class.Three string to be exact. I have tried this simple test code in my main app class.

settings.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), Settings.class);
startActivityForResult(intent, 0);}});

//Then a function
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent){
super.onActivityResult(requestCode, resultCode, intent);
Bundle extras = intent.getExtras();
String value = extras.getString("myKey");
if(value!=null){
Log.d("hmmm",value);}}}

In my settings.class I have the following
returnHome.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.putExtra("myKey", "YEAH");
setResult(RESULT_OK, intent);
finish();}});

Back in main app class it is not getting logged. Like I said I have three string in the main class that I want settings class to change and send back.

Android :: Blocking Intents From Launching?

Apr 6, 2010

On the market, there's an application called App Protector, which seems to effectively block the launching of configured activities until a password is correctly provided. By default, it blocks access to itself (not very interesting), Settings, and a few others. I wrote my own app to launch settings (rather than doing so through the home screen) and App Protector continued to do the job it claims to do.
When an activity that is protected is started, App Protector's password input activity is shown instead. Once the correct password is provided, the activity that was started comes to the front.
First -- does anyone know how this app is able to get between the rest of the system and the activities it protects? I would like to do something along these lines in my own application as well. Perhaps this app is receiving a broadcast about other activities coming to the foreground, and when the foreground activity is protected, it forces itself to the foreground?
Second -- does anyone know how well this technique will stand up to attack? Are there other ways to circumvent, where start Activity(...) fails to? It seems that one could use adb to un install it, thus removing its protection easily, but if I pursue my plans here, the app will be a part of a device's firmware (which, I assume, offers some protection against its apps being installed?)

Android :: Activity / Intents InTabs

Sep 19, 2010

Developers. I am a newbie to Android but a seasoned developer in UI, Java , and ECLIPSE. I am trying to do something I believe is very simple yet I am struggling. I have two tabs, A & B. I want to put an Activity in each tab. I want to have the 'B' Activity live inside 'A' so I can access it within 'A'. 'A' has a clock and every second that passes I need to update information in 'B', even if 'A' is not currently shown. I put 'B' into the 2nd tab as follows:TabSpec mapInfo=tabs.newTabSpec("tag3"); Intent intent = new Intent(this, MathleteMapActivity.class)mapInfo.setContent(intent); mapInfo.setIndicator("Course Map");tabs.addTab(mapInfo); I am totally confused on how to get the "MathleteMapActivity" Activity from the Intent 'intent'. There appears no way to do this. Can anyone please recommend a cleaner way to do this knowing what I am trying to do?

Android :: Separate Intents For Email & SMS

Jun 28, 2010

I have an app that has two buttons one for email & one for SMS. Depending on the button pressed I want to email or else SMS a certain text. I have coded the email button and it is working fine. The problem is that the dialog box that pops-up gives an option of e-mail or Messaging the text. I want to separate out the two, so that when the user presses email, only the options of email is there, and when the user presses SMS, only the option of Messaging is there.

Android :: Pending Intents In Notifications

May 13, 2010

I would like to show a notification that displays the progress of an ongoing operation. That works well for me. But at the same time the remote view should contain cancel button to stop the ongoing operation. The usual content intent should still do something else, i.e. not cancel the ongoing operation. It seems though that I can only have one intent. Code...

Android :: How To Populate A Menu Using Intents

Nov 3, 2010

How can I populate a menu using intents? I didn't understand that thing.

Or is there any better way for that?

Update:

Suppose I have an application that need to resize the image,and there are many other applications that have a capability of resizing the image. How can I show the list of applications on a menu in my application so that when clicking on a particular option it will invoke the intent associated with that application. Simply saying I could resize the image in my application with out bothering about how that will get done.
