Android :: Upgrading Application From 1.6 To 2.2 Emulator - Not Working

Oct 5, 2010

I currently found out, that my Application developed for Android 1.6 does not work on Android 2.2. I'm quite puzzled about this, because its a very simple Application which almost does nothing. The Expeption I get is like that:
java.lang.RuntimeException: Unable to instantiate application [packagename].AndApp:
java.lang.ClassNotFoundException: [packagename].AndApp in loader

The weirdest part is, that the Class it is searching for here does not exist and never has. The app itself does nothing than show some text in a textview. In Android 1.6 I dont get this problem and I cant see a reason, it event works in 2.1. The Manifest looks like that:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android=""
package="[packagename]" android:versionName="1.02" android:versionCode="3">
<application android:label="@string/app_name" android:icon="@drawable/stop_48"
android:description="@string/Description" android:name="@string/app_name">
<activity android:name=".DefaultActivity" android:label="@string/app_name" >
<intent-filter> <action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter> </activity>
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="4"</uses-sdk>

Android :: Device Chooser Picks Emulator (after Upgrading Ubuntu To Jaunty)

Sep 1, 2009

I just updated my Ubuntu Linux box to Jaunty (9.04). Initially, I had same problem everyone else has on Jaunty i.e. adb doesn't see the device: I followed the instructions and 'adb devices' lists my device just fine now, but Eclipse/ADT won't load my app or run it on the device. Every attempt at execution runs on the Emulator. I get the following message in the console: [2009-08-31 21:01:39 - KeyDirector] Automatic Target Mode: Preferred AVD 'avd15' is not available. Launching new emulator. Anyone have ideas on what might have caused this? I tried deleting and re-building the 'avd15' but it didn't help.

Android :: Server Sockets Stopped Working After Upgrading To 1.5

Jun 6, 2009

An application I'm working on stopped being usable after upgrading to 1.5, and the reason seems to be that, after joining a WiFi network and creating a TCP/IP or UDP/IP socket, there is no way to communicate using it from a remote entity. I can not even ping the phone using the normal ping command, which was possible using 1.0. This affects my program since it's using mDNS/DNS-SD and peer-to-peer TCP sockets for communication. Is there anyone else who can confirm this?I have tried running the program built with SDK 1.0 and SDK 1.5 while running on a real phone running Android 1.5 and the problem is still the same.

Android :: Application In Emulator Without Restarting Emulator In Eclipse?

Apr 8, 2009

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?

Android :: GPS Still Not Working On Emulator With R3

Jul 21, 2009

I've updated to 1.5 release 3 on both Ubuntu 8.04 and Windows XP Pro using Eclipse and latest ADT Plugin (0.9 Final). This snippet of code is still not working on the emulator whereas it was before 1.5. What am I missing here? The User Permissions are set to ACCESS_FINE_LOCATION and the minimal API to 3 and level 3 AVD. I set The Log.v still says the Location is null.

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.main);
LocationManager locmgr = (LocationManager)getSystemService(this.LOCATION_SERVICE);
if(locmgr == null) Log.v("err","Couldn't get locmgr");
Location loc = locmgr.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if(loc == null) Log.v("err","loc is null"); }
So is GPS emulation still broken?

Android :: Snesoid Emulator Not Working

May 10, 2010

I'm having problems with the SNESoid emulator. I downloaded some ROM's and unzipped them, I made a folder called 'roms' on my SD card. When I go to open SNESoid it says 'no roms loaded' and then I manually go to menu and open, and go to the folder and it see's the .smc files or whatever and I try to open them and it just takes me to the previous page, which is like the menu page with all my applications. I've tried to Google this problem and I've seen a couple other similar problems but never any solutions. Anyone know?

Android :: Progress Bar - Emulator Not Working?

Mar 23, 2009

I just wanted to run a ProgressBar test, as it's my first time using them on the Android. Here's my XML (in a Linear Layout):
<ProgressBar android:id="@+id/progress" android:layout_width="fill_parent"
android:layout_height="25dip" android:indeterminate="false"
android:max="100" android:progress="50" />

When I run the emulator I get a progress bar that glows orange on the left and right end. I also instead tried programmatically setting indeterminate to false, max to 100, and progress to a solid 50. No go. I even tried creating a background worker thread that would update the progress of the bar every half a second. Nothing. I just get two glowing orange ends to my bar (with a blank space in the middle).

Android Emulator Stopped Working

Oct 19, 2012

Need getting the Android Emulator working again for my project. It was working great earlier today, but after lunch I ran the program to debug and now have spend 3 hours trying to figure out why the emulator won't launch at all.

After running this I do get an APK and I can install it on my device. However, I would like to use the emulator for testing.

Android :: C2DM Properly Working On Emulator

Aug 20, 2010

I looked all over the web and in this group for a solution but I don't seem to have any luck. I'm probably not the only developer that needs to try C2DM on the emulator so a solution to this could be quite useful. First of all let me say that I'm running the latest Google APIs 8 rev 2 as AVD which should have all the necessary magic to allow me to run C2DM (it even has all the market components to run the LVL). I tried both Chrome to Phone and Jumpnote and it was impossible to make the C2DM service work. - Chrome to Phone fails when trying to connect from the Android app running on the emulator with a "Error: Unable to connect". On the Chrome to Phone site they recommend that Talk should be tried first and that the Market should be available (none of these come in the emulator image and I'm not sure if I should even try to install them on the emulator). - Jumpnote does not synchronize automatically and gives me an error: "Error calling remote note sync RPC" (when I do a manual sync I can see the docs being synchronized but looks like C2DM, which enables the auto sync, is broken). I also heard a comment that maybe port forwarding via adb could be necessary (but I'm really not sure this makes any sense).

Android :: Why 1.5 Emulator Not Working - Need Additional Permission?

Jul 14, 2009

After weeks of trying to get my service to run on boot & an interval via AlarmManager I finally found out the problem. If my workspace is for sdk 1.5, the service never run once. If my workspace is for sdk 1.0, Using the 1.0 Emulator, Not the 1.5 Emulator, it works perfectly. Why is it only working on the old SDK? Is there an additional permission I need?

Android :: Emulator Stops Working - Not Start At All

Jul 19, 2010

I'm using Eclipse and the Android SDK for Linux. When I start my emulator at the beginning of the day it works fine. Later in the day it's sluggish and still later it won't start at all. This computer runs Debian linux, the testing branch, with 1Gig memory and a two 1.6 Ghz processors. On another machine I have, the emulator works the same at the beginning and end of the day.

It has 500M ram and a single 1.6 Ghz processor. As it turns out I cannot use the second machine for all my daily tasks. How can I get the first machine to work? Is it the number of processors? I cannot figure out how to disable a processor in the emulator. I was looking at the '-qemu' options, but none seems to do the trick. I don't understand the qemu options that well.

Android :: How To Get Emulator Working For 1024 X 600 Resolution?

Nov 13, 2009

I'm trying to emulate an Acer AOD250 that has a 1024x600 screen and comes with Android. If I create an AVD with default settings except for resolution of 1024x600 and SDK 3, the emulator does not start. The largest I can get working is 670x600. At larger resolutions, sometimes the emulator starts, but does not complete the boot. Is there a memory setting or something that I can change to allow the emulator to work on a screen this big?
