I am writing a very small app that just opens the camera app ready for video. I am able to get my code to work on an Android 2.2 emulator, but it will not work on my device, Motorola Droid 1 stock 2.2 FRG22D. Any ideas where I went wrong on this code?

It appears ThorstenW is correct. I would upvote your answer if I had enough rep. You can see from the logcat that com.android.camera could not be found and throws a fatal exception. Logcat below.

When starting two activities of the same class within the same instance using the flag REORDER_TO_FRONT, the new extra information of the second call does not override the first starting activity. Is this the desired behavior? How do retrieve the new extras?
For example: In the StubActivity, I have this code:
Intent i = new Intent(this, A.class);
i.putExtra("foobar",1); startActivity(i);
Activity A is displayed, and then this code is called upon a button press:
new Intent(this, A.class);
i.putExtra("foobar",2);
i.setFlag(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(i);
Activity A is re-displayed. Now check for the extras: int foobar = getIntent().getExtras().getInt("foobar")
Turns out that foobar = 1
I had come across a code snippet which calls for an activity without referring to any context. Before, i was considering that context is used to tell about the calling component. But as i came see that another component can be called without any reference to context, it makes me wonder what purpose it might be serving. please put some light on it.
Here is the code which calls for an activity without referring to 'context'

A component I have created works fine if I put it in the main project and reference it from any res/layout xml, but when I put it in a project on which the main project depends, I get a ClassNotFoundException in the xml.
Whilst after compiling the interface works fine, it is a pain in the * to design an interface without seeing what I am doing because of the error. Does anyone know how to solve it?

I use a custom Parcelable to carry some data to a BroadcastReceiver. Here is what i do:
I register my intent and set the extra Parcelable on it along with an extra classloader (intent.setExtraClassLoader(..)). Next i schedule the execution of the broadcast via an AlarmManager.
So when the AlarmManager fires it looks at my intent with its parcel which it can not process since it doesn't use the supplied classloader (as it seams).
I think the classloader gets lost when Inten.fillIn copys the intent to a new one (see stack trace).

I have created and published my first android app. It's very simple. It works fine on simulator and some phones, but I am getting this error:

I am using the Hessian web protocol[1] or rather more the Android port Hessdroid[2] to fetch and unserialize objects from a web server. It works quite well but unfortunately I get this message:

When actually unserializing an object. The code within the library that throws the warning is:
CODE:.......
I guess the problem is that the class NewsSetCategory resides in a package and so cannot be loaded without the whole package name by the ClassLoader but this is a bling guess.
Is there a way to adapt the class path or to easily create a new PathClassLoader that will load classes directly from the package? Or does anybody else have any experience with Hessian on Android?
So I ran into a problem today while working on my Android program. I have a class that turns that an XML string into a Java object (third party) and it works fine in as a regular java project but on Android I get this weird error:

I hide my application name and my package for obvious reasons but I was wondering if anyone has ever encountered problems like this. Class is in the correct package, which is a library I have added. Other classes that I reference before are there and those can be made. Are there any other reasons a ClassNotFound Exception is thrown?
I am writing a application which will write to a file. Now I want to show the contents of the file but How do I delay the show function so that there is enough time for the writing to be done before continuing?
View 2 Replies View RelatedI've moved over from a Samsung Glyde (aka biggest pos ever) and am so far loving my droid. I'd like to thank everyone that contributed to the app lists/tips/tricks threads. All of it has made moving over to Android so much easier. Really, those kinds of things help us nubs
So far I've only had one real concern with the Droid, and I was wondering if this was unique to my phone, the Droid itself or if its an Android thing.
I downloaded Advance Task Killer as so many have recommended and have noticed that certain apps will simply start themselves running in the background it seems for no other reason than the phone sees the spare memory and fills it up in anticipation that I might run one of them. As you can imagine this is quite frustrating and annoying. Not only does it eat up valuable RAM space but also is eating battery (probably) in the process.
In particular, I notice the Corporate Calender, Voice Dialer, and Visual VM all tend to start themselves up on their own. What's interesting to me about this is I don't even use these applications. In fact, my corporate calendar is not setup, nor have I even opened it once. My phone could be sitting on my desk in sleep mode for an hour and then I'll wake it up and open Task killer to find 10 apps open that I never used.
How can i start an application just knowing the package name, not the classname? Ok, there is Intent.setComponent solution would be what i need ... if it was compatible with 1.5 :(
I guess i have to play with getPackageManager() but how can i use it?
I am running Eclipse on XP. The Emulator was running correctly but all of sudden today it hang up. I closed Eclipse, rebooted the XP, now when I invoke eclipse, it displays a ddms alert box with the message:
"Failed to initialize monitor thread: Unable to establish loopback connection"
and eclipe prints in its console: [2009-03-17 18:41:46 - DeviceMonitor]Connection attempts: 61
I can start the emulator manually but it's not linked to eclipse and eclipse still gives the same errors.
Why did it stop running and how do I fix it?
I'm testing JTwitter on an android app.
Code:
OAuthSignpostClient oauthClient = new OAuthSignpostClient(
consumerKey,
consumerSecret, "oob");
[code]...
I've included the libraries and all. When I run the app in the emulator, it gives the error 'Unforunately AppName has stopped'.
I would like to know if there is a way to lock (prevent) an application from starting.And i also would like to know if there is a way to prevent a service(application) from starting at boot of the device.i would like to know because i would like to create an anti-malware app.
View 1 Replies View RelatedWhen developing on BlackBerry or iOS, you can deploy your application just by dropping the compiled code into a special directory, and when the simulator boots up it will check that directory and install any apps that it finds there. Is this possible for Android? The reason this feature is desirable is because my build system deploys builds nightly. I want the emulator ready to go when my QA team gets in the next morning. To do that, I have to write a script that boots up the emulator, waits for it to start up, then calls adb install and finally shuts down the emulator. It would be great if I could just drop the .apk in a directory and have it ready to go the next time QA boots up the emulator.
View 2 Replies View RelatedI got to deleting a bunch of Spring stock apps using Titanium backup and now my marketplace won't download apps. :/ I was reading somewhere that Google talk might be the culprit (i did remove that)?
View 2 Replies View RelatedI can browse the internet fine, i can use any app that uses the internet like facebook, youtube, etc. I can even browse the android market fine. Its just stuck at "starting download". I really dont want to reset my phone.
I've tryed:
- restarting
- Turning off and on data connections ( both 3g and wifi )
- Clearing any google cache
- google talk
- deleting apps ( if its a space issue )
- canceling and restarting downloads
- have it attempt to download for 24+ hours
None of these worked. it seems reseting the phone is the last option. I have the Sony Xperia X10. Has anyone with that phone resolved the issue? Is it even the phone that's causing the issue? maybe the market itself is buggy.
I have a service running (Socket), this is how i start the service.
CODE:.......
But this doesn't seem to stop my service? Am i missing something? I need to destroy my service as soon as the home button is clicked.
I have four activity in a Tab and after the user clicked on the list I would like to start another one activity, but I can't use startActivity(Intent), because then I lost the TabHost view, and I get an activity witch is reserving the full screen:( So the user won't be able to click on the other tabs. What should I use? BroadCastReciver or What? If anyone have any good idea please help on me.
View 4 Replies View RelatedI have the code to get the list of packages installed in phone. I have represented the list in the form of Array List, below is the code snippet. But upon clicking in the package name I want to start that application, but how do I get the respective class name and package name to run? Is there any other method which I can try to start an application? arrayList<String> PackageNames = null; List<PackageInfo> lis = pm.getInstalled Packages(GET_MINIMAL); Pkgs = (ListView) findViewById(R.id.package_list); for (Package Info pi : lis)packages.put(pi.packageName, pi); PackageNames = new ArrayList<String> packages.keySet()); Collections.sort(PackageNames); PackageNames.add(0, "All"); pgs.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple _list_ item_1, PackageNames)); Pkgs.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> arg0, View v, int pos,long rowId) { Intent i = new Intent(); i.setComponent(new ComponentName(class name,packagename)); startActivity(i); I have tried intent to start the activity, but don't know the class name and package name to pass in the ComponentName() to start activity.
View 2 Replies View RelatedI'm starting an activity when a button is pressed, and normally (in other apps) haven't had an issue. But when I press the button in this app, I get an "unable to marshal value" error.Exact(ish) error from LogCat:
03-22 02:49:02.883:
WARN/System.err(252):
java.lang.RuntimeException: Parcel:
unable to marshal value
{CLASSNAME}@44dcf1b8
I feel that this might be related to the extra that I'm passing to the intent. I'm passing an ArrayList as a serializable to this new intent. My concern is that the data structure that the ArrayList contains isn't being serialized (as it's a personal data structure).Is the array list content data structure causing this? Something else that I'm missing?

This intent works, but it loads a menu asking which app I would like to use (Browser or Last.fm):

However, I just want to start the Last.fm app and skip the dialog asking which app to use, I thought maybe using the setPackage() method would work like this: i.setPackage("fm.last.android");

Is it possible to just start the Last.fm app?
Here's a copy of Last.fm's AndroidManifest.xml for reference.
I followed the directions verbatim in this Android tutorial, copying/pasting the code from the site to my app. http://developer.android.com/resources/tutorials/views/hello-tabwidget.html
However, when I try to run in the Android emulator, I get the error: "The application Hello Tab Widget has stopped unexpectedly. Please try again."
I tried debugging by introducing a breakpoint in the first line of the onCreate method, but the error occurs before the breakpoint is even hit. Any idea of what is going wrong, or any other way I can debug this issue? I am using Eclipse.
I have 4 Tabs in a TabHost...let them be A,B,C,D.... now each one is just an index page and clicking on any of them shows a different activity...
The problem is that i need to start another activity wen user selects something from the content displayed in the tab... The other activity should also be displayed in the parent tab itself... is it by any chance possible or i'll have to try some other way around?
I'm trying to start a floating activity from onStart to retrieve some info from the user right when the initial activity begins.
I have the following:
CODE:............
And callProfileDialog() is just:
CODE:..........
ProfileDialog.class returns a String from an input box. If the result returned is RESULT_CANCELED then I restart the activity.
The problem I'm having is that when the program starts, the screen is just black. If I hit the Back button a RESULT_CANCELED is returned then the initial activity shows as well as the floating activity (since it recalled itself when it got a RESULT_CANCELED). Why can't I get the activities show by calling ProfileDialog.class from onStart()? I got the same result when I called it at the end of onCreate() which is way I switch over to use onStart().
I have also tried the following:
CODE:.........
But this doesn't work either. It all works fine once I hit the back button but without doing that, it's all black.
