Can we based on Android Studio Emulators for different display screens create the App? Can we trust Android Studio Emulators ?
I mean for example whatever that's displayed on the Nexus 7 Emulator, would be exactly the same as it is really displayed on the real Tablet itself.
Yes, we can.
I've compared lots of emulators vs real devices - they are almost identical
Android Emulators give you a basic idea of different layout. Padding and pixel adjustment may be different in real device due to difference between system screen resolution and real device screen resolution.
The Android Emulator is built hand-in-hand with the Android platform for the Android SDK. Moreover, the latest Android Emulator system images (API 24+) 100% pass the Android Compatibility Definition, so that you can have even more assurance that app behavior will be exactly the same between the Android Emulator and a physical Android device.
I am going to create an app for devices with Android OS 2.1 and higher. As many developer I met layout problems and after reading about that in the official android documentation I decided to follow a way; I created 6 directory one for every screen density (ldpi,mdpi,hdpi,xhdpi,xxhdpi,xxxhdpi). What I want to know is if I did it right, I know that layout could be not exact at 100% but could I'll meet serious problems doing that?What I should do?
The second problem is checking app in many devices in the same time, I use Android Studio and I am able to create devices and use emulators but there is a plugin or a website or something else I can use to test quickly the app in tens of Android devices without set all manually?
Thanks in advance!
I created a small app using following this tutorial.
App runs fine on Android but after running on 2 mobiles both running Android 4.1.2, I find that in one mobile the layout was broken. I mean button borders are broken.
Any suggestions on what is going wrong here ?
Using latest ionic framework and cordova.
This mostly happens because different mobile screen size.
You should create different layout files for different screen sizes

I have wrote an application using android 2.2 in eclipse.
My app is working fine on the samsung galaxy mini android 2.2. However, it is not working on samsung galaxy s3 android 4.1.
My app is only taking up half of the screen on the samsung galaxy s3.
Why is my app not working on higher resolution devices?
How can i make the app compatible with other devices running
different versions of android?
Sounds like it's most likely you just have a LinearLayout at the top of your layout XML and it just takes up less space on the S3.
I would advise taking a look at the two links below; if you want a specific starting point, you could adjust your layout to match_parent and use the l/m/h/xhdpi folders to place different size graphics in. Also worth checking whether you are using dp or dip (density independent pixels)

The best way to ensure that your app will work on other devices is to get access to other devices and test your application on those devices before you release.
Another way is to make sure that you are targeting the correct SDK you need to target and use the AndroidSupportLibrary when needing to have backwards compatibility.
For us to help with your specific problem we would need more details as to what exactly is going on, but make sure the packages and libraries you are using are compatible with the android versions you are trying to target.
And make good use of the AndroidSupportLibrary.
Did you check the resolution compatibility? This seems more like an Android Manifest issue then an Android version issue.
i always working in android mobile devices. i want to run my projects in android tablet devices.
so my questions are
do i have to face any compatible issue?
will same project run with different view in different target such as one for tablet one for mobile device?
in example can it set in android mainfest.xml so it can choose different view in different device
and please help about how to solve this, with some help link
thanks in advance.
Have you looked at the android developer site on this?

It covers the issue in detail.
