The apk or app name can be retrieved using package manager. According to alex's answer here - https://stackoverflow.com/a/30348666/2026280

Assuming you have the path of the apk file.

public static String getAppLabel(PackageManager pm, String pathToApk) {  
PackageInfo packageInfo = pm.getPackageArchiveInfo(pathToApk, 0);

if (Build.VERSION.SDK_INT >= 8) {
    // those two lines do the magic:
    packageInfo.applicationInfo.sourceDir = pathToApk;
    packageInfo.applicationInfo.publicSourceDir = pathToApk;
}

CharSequence label = pm.getApplicationLabel(packageInfo.applicationInfo);
return label != null ? label.toString() : null;
}
