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.
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 have an app in development that runs fine in the emulator but wont run on any android device, when the application icon is clicked the screen goes blank for a second then returns back to the device apps page, i have experimented with setting different permissions but it does not seem to solve the issue. Any ideas?
