How to get the application name of the APK programmatically (not installed)

Based How to get the name of the application in android?.

I have this snippet. `andPath| is the location of the APK.

PackageInfo info = getPackageManager().getPackageArchiveInfo(andPath, 0);
ApplicationInfo appinfo = info.applicationInfo;
String packageName = getPackageManager().getApplicationLabel(appinfo).toString();

PackageManager pm=getPackageManager();
ApplicationInfo ai;
try {
     ai = pm.getApplicationInfo(packageName, 0);
} catch (final NameNotFoundException e) {
     ai = null;
}

final String applicationName = (String) (ai != null ? pm.getApplicationLabel(ai) : "(unknown)");

applicationName returns me the package name.

CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName,PackageManager.GET_META_DATA));

c returns me null.

Does anyone know what I'm missing here?

Simply use regular expression to get the name and compare with the app Label.

public String applicationLabel (ApplicationInfo info){
     PackageManager p = con.getPackageManager();
     return p.getApplicationLabel(info).toString();
}

I hope you got application info pass that application info to this function it will give application name.

This is how you can get the application label from not yet installed 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;
}

No need to patch the applicationInfo prior to SDK 8. See this issue for more details.

if you have a problem here i post the full code to get the application name

its returns ApplicationInfo

public List<ApplicationInfo> getApplicationList(Context con){
        PackageManager p = con.getPackageManager(); 
        List<ApplicationInfo> info = p.getInstalledApplications(0);
        return info;
    }

it returns ApplicationName

public String applicationLabel(Context con,ApplicationInfo info){
        PackageManager p = con.getPackageManager();
        String label = p.getApplicationLabel(info).toString();
        return label;
    }

on your onCreate function paste the below code 

List<ApplicationInfo> info = new ArrayList<ApplicationInfo>();

        info = list.getApplicationList(this);
        LinearLayout layout = (LinearLayout)findViewById(R.id.content);
        layout.setOrientation(1);
        int size = info.size();
        Log.d("size",String.valueOf(size));
        for(int i=0;i<size;i++){
            Log.d("Val of I",String.valueOf(i));
            String appname = list.applicationLabel(this,info.get(i)).toString();
            Log.d("AppName",appname);
            TextView tv = new TextView(this);
            tv.setText(appname);
            layout.addView(tv);
        }

    }
