How to get the Android device screen size from the adb command line?

Question

I need a way to detect device screen size and density with adb. If there is no solution, where can I get the complete list of all existing android device with their screen

Answer 1

To get required info from ADB, the following command executed from the command line will return a lot of useful properties about the connected devices

> adb shell getprop

To filter through these properties

on Unix use grep like

> adb shell getprop | grep density

on Windows use find like

> adb shell getprop | findstr "density"

Returned value looks like

[ro.sf.lcd_density]: [240]

for screen size put display instead of density

Answer 2

You can get screen dimensions with this code:

public int getScreenHeight() {
    return getDisplay().getHeight();
}

private Display getDisplay() {
    return ((WindowManager) getContext().getSystemService(
            Context.WINDOW_SERVICE)).getDefaultDisplay();
}


public int getScreenWidth() {
    return getDisplay().getWidth();
}

Once you have the Display in the code above you can use DisplayMetrics to get the density. DisplayMetrics will also give you absolute display with and height.

ANDROID:/ # dumpsys window | grep  mGlobalConfiguration                                                                                                                                                
mGlobalConfiguration={1.0 ?mcc?mnc [en_US] ldltr sw720dp w1920dp h532dp 160dpi

So resolution is 1920x720
