How to get the size of installed application?

Question

I am trying to calculate the size of the installed application.

I found an answer here

I have tested it on some devices, and there is no problem except Samsung Galaxy Note3(4.3).

I get this error: java.lang.NoSuchMethodException: getPackageSizeInfo()

I'm wondering is there any other way to get the size of an installed app?

Answer 1

try this...

public static long getApkSize(Context context, String packageName)
        throws NameNotFoundException {
    return new File(context.getPackageManager().getApplicationInfo(
            packageName, 0).publicSourceDir).length();
}
