I coded an Android application under eclipse
I run this application
The emulators starts and show the Android desktop
But my application is not shown/added on it.
Neither the main activity is started.
What to do ?
Go to Settings>>Applications>>Manage Applications then click on the All tab and here you can find the list of the applications installed on your device or emulator. So just ensure it wheather your application is installed or not.
I am a beginner too and so far I only manage to test the samples that are packaged with the platform. I had the same problem but when I change the emulator platform and API level everything is working.
Maybe you try to make few different emulators and test run your app on different emulator

Android Studio Not Showing My Phone for Run Application:
I want to run my developed application directly on my phone but I'm unable to run this. Because It's not showing in android studio. It also not working on emulator also. I already ready Google Development Guidelines(https://developer.android.com/studio/run/oem-usb.html). But these are not working for my system.
Have you enabled Developer mode on your phone?
If you haven't done yet follow these steps:
Go to settings -> About phone.
Tap on Build number 7 times and the developer option will be on.
If you have already enabled it then:
Go to Settings and find Developer options.
Check whether it is enabled or not.
Swipe down and find USB debugging. This option should be enabled. (Also enable Wireless ADB debugging if you're running app wirelessly)
Sorry for the late answer
I am also facing this issue couple of month ago, I had checked that I had enabled the USB debugging in developer but there is an issue with the Redmi phones that along with the USB debugging you will need to do the following
Go To Settings > Additional Settings > Developer Options
Enable USB debugging
Enable Install via USB
Disable Turn on MIUI optimization
On Select USB configuration select MIDI or File transfer (this is
what solved the problem for me)
also, keep in mind to give an RSA permission

I have solved my problem on my own. The problem was in Android SDK. I'm using 2 windows in my same pc so I just used android studio on my another window then it's was working perfectly so I thought i have to try with changes that windows Android/Sdk folder in other windows which one I had problem. So I just copy (C:\Users{MyUserName}\AppData\Local\Android\Sdk) in getting the problem window and try again the android studio & Wawu... It's starting working. I hope it's will be helpful for you also.
i just made a simple android app with 6 buttons. Each button on click opens a new activity. I installed the app on my device via USB cable from Android studio and it runs fine on my device.
But here rises the problem, when I installed the app on my friends device after sharing via SHAREit the app installed on his device but did not run.
What could be the reason for this? And how can I solve this?
Please help. Thank you
You dont need to create a signed APK if you only want to test it on your friends device and not to run it in a production progress. Android Studio creates an apk automatically which is signed for 365 days. Just open your project in your explorer and go to [ProjectName]\app\build\outputs\apk and select the app-debug.apk.
Make sure instance run in android studio is disabled.
Because if Instance run is enabled when you debug the app on real device through usb debugging it will work properly . but if u share the apk from your device to other device it will not work. It might show an error . App Name Unfortunately Stoped.
If Instance run is enable. you must disable the instance run first. If you don't know how to disable it just google it. After disable the instance run, you must clean project and Build new apk. It will work on all the other devices without generating signed apk.
Hope it may help you.
While building the app what MinSDK version you defined? Do both devices satisfy that criteria?
If you suspect that installing through sharing app is a problem then try attaching your friend device to your laptop and try running the app.
Or
Send the apk through email and let your friend download the apk and install the apk through apkInstaller app.
I have a solution for you:
Install Bluestacks Android Emulator.
Go to Tools, Android and click on Enable Adb Integration to disable it.
In android studios one Android Device for Bluestacks will appear while installation.
Share the installed app through shareit.
It will work on other device.
Hope it helps
Here is the link, where you will find your solution. https://developer.android.com/studio/publish/ check the point 'publish your app', In left column.
Simply follow these steps:
Double click on shift and search for build apk and click on it.
Locate that apk file.
Copy to your physical device or your friend's device... whatever, it will work.
I'm new to Android app development. I'm trying to write an application which when run on two android devices will be able to communicate through sockets.
I'm little confused on how to test it. I'm using Eclipse in which launches an emulator. How can I get another android device to run my application and how to make socket connections between them.
You can launch the other device using command line. Read this for further guidance:
http://developer.android.com/tools/building/building-cmdline.html
You can run on all available devices.
In your project go to Properties -> Run/Debug Settings
select the launch configuration and click Edit...
go to the Target tab and select Launch on all compatible devices/AVD's
Just create a second AVD and bingo
Well i `ve made an app using java me and as graphics i used lwuit library which i added into the midlet`s jar. On Nokia it runs smooth and i wanted to port it to android. So i found out about microemulator http://microemu.blogspot.ro/2008/11/running-java-me-applications-on-android.html and i followed those steps and i got the apk. However when i run it into the Android Emulator it closes at start. I don`t know what may be the problem because i was able to convert the demo jar app into apk and it ran succesfuly.
Any ideas on what should i do?
I suggest you port your application to Codename One which should be pretty simple. It has proper Android support which will make your application look and act native on Android.
I cannot test build Android application on my HTC Evo at all. I searched online for answers, but nothing helped, including updating all the software.
The Eclipse launched Emulator doesn't recognize it as an external device either.
Any ideas? I have a presentation at my job tomorrow, and it has to be on the phone.
As said above you need to download Drivers separately. You can download HTC Hero drivers from here
Just unzip and refer this path so that eclipse could recognize your device
