In RIM there is a "ApplicationManager.getApplicationManager().launch("String path")" method that launches directly RIM application mentioned in "String path".
Is there any method like this in android or any other way to solve this problem ?
Say I have developed 4 applications. Is it possible to group these applications, so that I can access and launch these from one location?
Can the below flow work? Start an Application|Display launchers(icons) for 4 different applications|On click of the icon start the respective application.
I have written an application which calls native methods through JNI. In the native library 4 threads are started. On USB removal, the application is to be closed including the native threads. Upon receiving the USB removal event, we are trying to kill the threads (pthread_kill() ) and then finish (using finish()) the activity. After reconnecting the USB, the application is not launching due to memory corruption. In DDMS, it shows the threads are still attached to bionic. As the threads are not closed, I feel the resources were not released properly. If I reconnect again then application launches and works fine and the same repeats on every launch.
To solve this problem Can I use System.gc() ? Can I use pthread_exit() 1st and then pthread_join instead of pthread_kill ? Whats the procedure in Android to kill the native threads and also the application ? After the application is closed, will it not be listed in DDMS ?
I want to launch my application in market. I ahd go to http://market.android.com/publish/signup but there they are asking for Website URL. But i don't have any website then what should I enter there? or is it necessary to have our own website to launch application in market?
View 6 Replies View RelatedMy app has 4 activities on the stack A->B->C->D (top)
If you press home and re-enter the application, another instance of A is started, so the stack is A->B->C->D->A (top). I know this because when I press BACK, A is popped off and I now see D (instead of going to the Home screen).
What I want is that when the user re-enters the app, they re-enter on the same activity they were in before (D).
CODE:................
Is it possible to re-use all the instances of Activities and Services when an application is launched twice. For instance: 1/ I start my application APP1. Some activities are launched and a service is started. 2/ I click "Home" device button 3/ I can see the icon the launch again my application APP1 4/ I click on it and the APP1 is launched twice
I would like to re-use the existing the instances of Activities and Services from the first launch. I guess it is related to "SingleTop" or "SingleTask" but it doesn't seem to work.
Is it possible to launch an app widget from another application.
For example, I have a button in an application. When I click on that button, an appwidget must be launched.
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?

View 2 Replies View RelatedI am trying to launch another application from my Activity. Something weird happens when I am running this code :
Intent myIntent = new Intent( Intent.ACTION_MAIN, null );
myIntent.addCategory( Intent.CATEGORY_LAUNCHER );
myIntent.setFlags( Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED );
ComponentName compName=new ComponentName(myArray[i][0], myArray[i] [1] );
// String[][] myArray myIntent.setComponent( compName ); startActivity( myIntent );
I have this error :
android.content.ActivityNotFoundException: Unable to find explicit activity class { com.android.settings/com.android.settings.Settings};
Have you declared this activity in your AndroidManifest.xml?
But when I replace this line
// myArray[i][0] = "com.android.settings" // myArray[i][1] = "com.android.settings.Settings" ComponentName compName=new ComponentName(myArray[i][0], myArray[i] [1] );
with ComponentName compName=new ComponentName("com.android.settings","com.android.settings.Settings");
And without any modification in my manifest, it works!
I am looking for a way to launch my application(few Activities, Services, Receivers) from the Setting menu.
In other words I am interested to know:

2. Did someone has done such task before ?
3. What APIs and application's code should I learn
I am launching Google map application from my application, using
Uri.parse("geo:" + "13.042206" + "," + "80.17000?z=10");
and its working fine. But I want to show direction between two latitudes and longitudes, for that I tried using this uri,
Uri.parse("geo:" + "13.042206" + "," + "80.17000" + "geo:" + "9.580000" + "," + "78.100000?z=10");
But I am getting a Toast telling "Unable to load the url".
Is it possible to launch other apps from my app like the application launcher or home screen do? I don't want to try a home replacement app. At least would a widget on home screen be able to launch other applications? Also can a widget on the (default) home screen receive swipe events (before a touch event)?

I check the box, it tells me that I can clear the setting in Application -> Manage Applications. I launch the Music Track with the box checked. I go to the application settings, but the "clear defaults" button is always enabled. It was already the case with 1.1 SDK, 1.5 does not help (tested on emulator 1.5 AND ADP1 with 1.5 recovery image).

View 3 Replies View RelatedHello, I would like to create a zip file from files located on the sd card, I have managed to do that using java but I think that the result is too slow, so I thought of going native using the android NDK.
My questions are:
Does anyone know any C/C++ library to zip unzip files that will work on android?
How to know if the library will work on android?
will this make any difference on performance?
I have made a game with just one activity.. I just replace the views when I want to change screen. The game runs fine for a really long time inspite of what ever I do within the game.
But once I close the main game, by calling finish on the only activity in the application, and then when I start again, within the next 30 secs it crashes telling VM budget exceeded..
When I don't have a dispose() or a delete method in JAVA.. how the, am I supposed to remove the objects used in memory.. moreover I have android:launchMode="singleInstance" in my manifest

View 2 Replies View RelatedWe want to migrate a huge complex native program to Android system ,running it as a background service accepting command sent from Java Program using JNI along with IPC. However, the Android NDK state following words:
Please note that the NDK does not enable you to develop native-only applications. Android's primary runtime remains the Dalvik virtual machine.
Does that mean we have no way to run an standalone native-only application on Android as a background service? The native code can only exist in the form of library that will be loaded to the virtual machine through JNI?
We want to develop an application blocking feature in our project.
Our application (say application "A") will block the installation of specified app (say malicious application "B"). Then we need to know when the application "B" is in installing process.
Is there any APIs about this, or can some one give me a hint on this?
I tend to believe that developing mobile applications in an enterprise environment is best suited by developing intranet web applications. That said I have been asked to think about whether there are specific enterprise applications that could only be accomplished or would be more successful as native applications. I am curious as to what the Stack Overflow community thinks.
