I am trying to run the simple "Hello World" program in Android Studio for last two days but whenever i run the app, emulator opens but app doesn't even after waiting.
I tried a lot of things from internet but nothing worked. Please help me out or suggest some other alternative to run and test the app.
Sometimes the app does not launch automatically in the emulator.
In the emulator, open the app drawer (the screen where you can see all apps in the emulator) and see if your app is in the list of installed apps.
Otherwise, you're having another issue.
Note: I suggest that you use the Genymotion emulator. It is far better than the default Android emulator.

I have been trying to run my app but whenever I run the emulator I do not seem to find my app anywhere. Is there something wrong with the emulator? or my app?
Thank You
If there is't any error after running on emulator, and you don't see your app's pakage on the emulator, try to create another AVD and test on it.
I've been working with PhoneGap for about two weeks now, yesterday I've build a new android app all went well except that the app starts very slow on my android device. It first shows me for three seconds just a black background except the navbar. So I want to ask how to boost it up or which files I could remove or what I've done wrong please I would be happy if you explain me also the file structure. Thanks in forward for your answers!
Your question is little bit vague. Please, give us more information about your app, about your config and what you’ve already tried.
If my app is slow on any device, I do generally the following:
Check if the same problem occurs in the browser
What’s going on at the start of the app in the browser (Chrome Dev Tools)
If nothing unusual happens, check the logs on the device
For Android, I’m using Logcat for checking what’s happening on the phone.
In order to use Logcat:
1.) Enable debugging mode on your Android phone
2.) You need Android Studio
3.) Connect your phone to your computer and start Logcat in Android Studio 3.1.2
4.) Check the logs while you are starting your app on the phone
So I'm using an Android emulator (the stock one) to test out my react native application I'm building.
I can load my app on the emulator using react-native run-android and then my app loads fine. However I can only ever do pretty much one interaction, such as pressing a link, after that my app just doesn't respond and I have to restart my react packager to get it to reload. Are there any reasons why this might be happening and how this can be resolved please, it's making it super hard to develop any project.
There is no strenuous code in place and runs fine on my IOS emulator.
I've been having similar issues, especially after rebooting the emulator. I've found that the best solution is to reset the emulator and check the wipe user data box. You then need to wait until the emulator is fully booted before starting the packager. This works for me most of the time in 0.14, but isn't foolproof. I would also check the chrome debugger and make sure there aren't any IOS exclusive parts of the code causing issues, but I'm guessing you've tried that already.
I have written some codelines with libgdx in eclipse and want to run them on my android device.(It's a tablet)
But i cant find out how to do this.
I even cant run it on the android emulator provided by the android sdk. I get an error that the app stopped unexpectedly.
The app is working fine with the desktop launcher...
I hope someone can explain me how to get it working on the emulator or on my android device.
I saw somewhere that simply connecting my device via usb should be enough that eclipse is able to create an temporary app on the device, but this also didnt work.
Regards
1st of all, download SamsungKies[latest], to get and install proper USB Drivers. Its important that it should be the latest, cuz there was a bug in the previous versions.
Now that you have the drivers, simply connect your device to your machine IN USB DEBUGGING MODE.
Go to your main activity, and run.
If it launches in an emulator, close the emulator, and again in main activity, select run configurations -> Android Applications -> target -> always prompt to pick device.
Run again, and it should install and run in your phone/tablet.
NOTE:The activity closes in emulator because, by default, the emulator doesn't support OpenGLES emulation, its too heavy for your CPU.
i know its kinda late, but i hope it helps others:)
I am trying to write an android application and my workflow is as follows:
Write some code
Click run as Android Application
Eclipse then starts the android emulator
Install the app on the emulator
Run it
It seems to me that there is no need for it to start an android emulator(3) each time and to kill it. It'd be nice if there was a way an android emulator always running and eclipse just installs/uninstalls the app instead of making me wait every time.
Does anyone know a way of doing this?
Yeah, it just does that way - leave emulator on, and "run" in Eclipse will update the app and run it. This is how it works for me.
Just don't kill the emulator!
