This was appearing again & again, So I gave a restart, & still it is same as above error.
Even after trying all the possible solution it is still at this stage.
& Once it start appears like this in emulator
I installed VS2017 a few days ago, created the simple app Build your first Xamarin Forms App, and now I want to debug.
I am having issues with the default Android emulator created by the VS2017 installation (Android_Accelerated_x86_Oreo) so I created a new emulator. This is the screenshot.
How can I change the default so it debugs in the newly-created emulator?
I wanted to point out that I'm new to all of this, so I would like to run it without having to install anything else. I would like to see something run before I install anything else.
I also wanted to point out that I've tried clicking on "Start" on either one of them when not in debug mode, and I get Could not start emulator. Unable to load DLL 'DismApi' error.
The only way it automatically starts is if I hit F5 and the emulator window pops up. Then I go to Tools > Android Device Manager and the default emulator says "Stop" (it's running). If I click on "Stop" and then press "Start", I will get the same error again: Could not start emulator. Unable to load DLL 'DismApi'.
Where you launch the debugger just click the arrow pointing down to open the dropdown. Then select you new device. It will stay as you default device. Please see the image for reference:
Note: You may have to restart Visual Studio for your new device to appear.
I'm new to Java, haven't used Eclipse in probably 2 years. We're starting up a mobile dev team at work, and I'm just going over the tutorials on the Android site:
http://developer.android.com/training/basics/firstapp/running-app.html
Simply just created a project, launched the virtual device manager, have that emulator running, then click Run -> Run as Android application in Eclipse .
I've been staring at this screen for about 5 minutes now:
It says "Launching (100%)" in the bottom right corner of eclipse, and this Progres window just says Launching, but the emulator isn't doing anything.
I know emulators are generally pretty slow... But is this normal or did I do something wrong?
That happened to me too, and still does at times:
Close the emulator and execute the program again
If that didn't work, execute the program while the emulator is running. A new emulator will pop up, close the old emulator
If that didn't work, delete device and create a new one.
Also, is there anything at all popping up on the Logcat view?
I would recommand checking the list of process afterwards. Sometimes when i brutally terminate an app in eclipse, the process is still running.
But i'm on PC and i use an older version. Maybe it has been fixed.
I'm a newbie that needs some help on getting the AVD running with my app. I've been developing C code for decades, but I have to admit the Eclipse/AVD setup has me stumped! I'm following the 'HelloWorld' tutorials on the developer.android website (and some others) and everything seems to be working OK, up to the point where I try to run it on the AVD simulator. I'm not getting any warnings, the Eclipse build/run output window says that everything is installed OK and the AVD does startup and run. Eclipse says that my app is loading, but it never runs. All I get is the simulator window with "ANDROID" on the screen and the buttons on the right-hand side.
I've got Eclipse Indigo and r18 of the Android PlugIn (I tried to install Helios, but the Eclipse website directed me to Indigo!). Is Indigo OK for running the simulator, or do I specifically need Helios? I also have Java 1.7.
The API level I have installed is Level 15 (v4.xxx of Android, I think). Don't know if I need a lower version to get my tutorial app to run, but level 15 is the only one I can select when setting up a device in the AVD manager.
I've been trying to get this going for days, trying all sorts of switches and buttons, but to no avail. Before I start uninstalling everything and reinstalling, can anyone advise if there is anything I might be missing, or has tripped over this problem themselves and found a way around it? Something that always trips up new starters maybe? Or do I need to go back to scratch?
Any help would be much appreciated.
How long are you leaving your emulator running after you attempt to launch your application? The Android OS can take a long time to boot up in the emulator. If it's stuck on the "ANDROID" screen then you're either not waiting long enough or there's something wrong with your emulator. It should eventually boot into the normal Android lock screen or home screen just like a device.
You can launch your emulator ahead of attempting to run your app by opening the Android Virtual Device Manager (toolbar icon in Eclipse, if installed properly) and then selecting an emulator and clicking the "Start" button. If you don't have any emulators listed, then you need to create one by clicking the "New..." button.
When I try to run the Android 2.3.3 emulator, the phone desktop doesn't show.
Instead, this error message keeps popping up :
The Application Launcher (process com.android.launcher) has stopped unexpectedly. Please try again.
I keep force-closing it but it just keeps popping up.
However, any application that I try to run (I'm using Eclipse Helios for my IDE) runs fine in the background.
How do I get around this?
you could look into the console view in eclipse.
or you could call
platform-tools/adb catlog
to display the java log.
