Android :: Phone Application Not Launching On Emulator
Nov 16, 2010
I'm testing a simple hello app and it's not launching on the emulator. There's no errors and the console is this:
[2010-11-16 21:26:06 - Hello World] ------------------------------
[2010-11-16 21:26:06 - Hello World] Android Launch!
[2010-11-16 21:26:06 - Hello World] adb is running normally.
[2010-11-16 21:26:06 - Hello World] Performing com.hello.HelloWorld.HelloWorld activity launch
[2010-11-16 21:26:09 - Hello World] Launching a new emulator with Virtual Device 'VirtualDevice2.2'
The emulator launches and the screen appears with the lock and my app doesn't start. Tried to unlock and go to launcher to look for my app and it's not there. Anyone can help me on this one?.......

I have problem launching my app. The emulator will load, but the app won't launch. The progress bar at the lower right of eclipse is just stuck at 100%. I've tried reinstalling everything including my JDK's and adt plugin. Also tried kill-server and start-server method but it didn't work. There's even nothing written in console or logcat. I even tried waiting for an hour hoping it would run.
I have windows 7 64 bit.

I want to launch another application through the current application.
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 ?

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 ?

My 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).

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.

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?

I 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 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)?

Example: I have a button which starts an activity with GET_CONTENT audio/* I have a menu with choices: Music Track or Sound Recorder and a checkbox. 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). I also tested the allowClearUserData flag but it seems we cannot clear anything but the cache (for the webview ?)

I got a null pointer exception in an Activity onCreate() while trying to access my Application object (extended from android.app.Application).This exception occurred very rarely and i have no way to reproduce this again.My App starts a service on BOOT_COMPLETED intent and the null pointer exception seems to have occurred during boot up. Can somebody please throw some light on this issue? Application should have been created before creating any activities.

I have an android application which allows the user to open up google maps or navigator to show a certain address. This functionality was working in the past, but now I get the following error and the app crashes:
ERROR/AndroidRuntime(2165):
android.content.ActivityNotFoundException:
No Activity found to handle Intent { act=android.intent.action.VIEW
dat=google.navigation:q=MCNAMARA+TERMINAL+ROMULUS+MI+48174 }
The two intents I'm using are-
1) For Map:
String uri = "geo:0,0?q=MCNAMARA+TERMINAL+ROMULUS+MI+48174";
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
startActivity(i);
2) For Navigator:
String uri = "google.navigation:q=MCNAMARA+TERMINAL+ROMULUS+MI+48174";
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
startActivity(i);

Is there a way to reload an Android application in the emulator without closing the emulator, saving any code changes, and running the emulator again? If I make even a simple change to the layout, it takes about 30 seconds by time I run it in Eclipse and Android "boots", and I can unlock the emulator to run the application. Is there any way to shorten this time when making changes, or is it something I just have to deal with?

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

Although I have seen several threads and tutorials on this topic, I guess I still have some confusion on how an application can be chosen from a list of applications to display a file.
I have a Activity which has a list view in it. This list view is bound with file paths (so a file browser of sorts). When we click on a specific file type, I need a list of applications that can open that file.
So far this is what I have in the OnItemClick for the list item:
CODE:............
When I run this on my phone, the error is:
No Activity found to handle Intent { act=android.intent.action.VIEW cat=[android.intent.category.DEFAULT] dat=file:///
When I do the same in a file browser application (downloaded from the marketplace), I get two options (QuickOffice and Word to Go), both of which I have installed on my phone.
Could someone guide me as to what else is needed here? Things I have tried besides the above:
Add the following entries to the manifest:

You can see property action android:name= property is "android.intent.action.MAIN" and categoryandroid:name= is "android.intent.category.LAUNCHER" for all activities.When application starts up, it calls First Activity. Then calls useless Activity such as ThirdActivity or Second Activity.In this case, is my manifest.xml correct?Or, do I need to set another property to Second and Third activity? If so, what is that?I wonder manifest.xml file is right for my case.
