Do you know any way to keep the phone screen on when i run application on it from Eclipse?
I'm using my phone to test Android app and it is very annoying to turn on the screen every time i run the application.
Do you have a solution?
Use the option Keep screen on under the developer options of your phone/emulator.

I have tested my application using ionic-serve and everything run normally.
But, when i tried it using device, the application will first run the splash screen (which is not run when using ionic serve) and nothing happen, only white screen.
Can somebody please help me with this situation?
I have no idea about what happen.
The white screen issue often occurs on devices and not in the browser when you are injecting something into a module that kicks off your app. Try to figure out which one, and remove it (if it's not being used) or update it.
First thing to do is to check for errors in the log. To see them, type the address chrome://inspect/#devices in chrome, and click on your app. You'll need to make sure your device has usb debugging turned on.
I'm new in Android developing (I'm a developer iOS from 3 years) and the very first thing that I notice in Android is that when I install my app from Android I need to unlock the screen manually.
This might seem like an unimportant thing but very often I'm wait in front of the screen for a few seconds and then I realize that I have to unlock the device manually.
Thanks
Well, I don't know about auto unlock but you could set "Stay Awake" in developer settings on your phone. This means the screen will not lock when you are connected to your computer. Not compatible with all phones due to some screen types.
Also, you could have a scout around the Play Store. There are numerous attempts at this but with varying results I suspect.

Hi， I'm new to Android development (please excuse me for this elementary question) and am currently developing a simple app. However, when I run the app, the screen stays on unless I exit the app.
When running most other apps, the phone screen will automatically turn off after several minutes. How can I set it so that the screen automatically turns off after running my app after idling for some time?
Thanks
Uncheck the Stay awake in Settings->Developer Settings.
We have designed an hybrid app which is a bit heavy (9 MB). Problem is that at times, minimizing this app (home button) makes the app reset in background i.e. its app cache is lost and app reloads from splash screen. After minimizing we worked with other apps in tablet (Galaxy 800).
We saw this problem only if we tried to launch app from the icon in launcher. This problem did not happen when we tried to launch it from the minimized list(recent apps button).
This problem is not specific to the tab. It also happened in Galaxy 3 and Droid Razr also.
Any guidance?

This is perfectly normal.
Computers, phones, and tablets do not have infinite RAM. Android's approach to this problem is to keep your process around for a while after the user has left it, but eventually Android will terminate your process to free up RAM for other applications and their processes. You can read more about the Android process model in the documentation.
It can be possible that ‘deep clean' option is enabled by mistake on your phone. What deep clean does is, whenever you minimize an app , it releases all the memory associated with that app, and hence when you again open that app, it will start as if it is new. To check the 'deep clean' option,
go to the
Developer options -> 'Don't keep activities' -> disable it
If it is not disable please disable it.
I followed the tutorial to the letter. I select run then the emulator starts up. Problem is that I never get to a home screen, nor does the text hello world display.
Is there a way to test my installation of the emulator?
Take into account that the android emulator takes some time to load.
Wait for a few minutes and check logs on the DDMS to see if everything is loading correctly.
It does take a while to start up. But remember that you don't need to close and run the emulator every time you want to test your project. Just leave it open and it'll just launch your application when you want to run it.
I had the same problem and discovered (by clicking all the buttons in the emulator) that if you press the home button (little house) then the launcher icon (grid of squares) that the app I was launching had been successfully installed and I could run it by clicking on it. I still don't know why running it from Eclipse wasn't getting all the way into the app, but at least it was installed and I could run it from the emulator.
Press and hold the power button in the emulator.
