Android: how to get the name of apk file programmatically?

For some reasons, my app can be installed with different apk names. At launch, I would like to know what is the name of the apk file. Do you know how to do that ?

Thanks !

final PackageManager pm = getPackageManager(); String apkName = "example.apk"; String fullPath = Environment.getExternalStorageDirectory() + "/" + apkName; PackageInfo info = pm.getPackageArchiveInfo(fullPath, 0); 

you can got it with:

info.versionCod 

and

info.versionName 

hope this help you

The apk or app name can be retrieved using package manager. According to alex's answer here -

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; } 

try this:

ActivityManager actMngr = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE); string runningPkg = actMngr.getRunningTasks(1).get(0).topActivity.getPackageName(); PackageManager pm = context.getPackageManager(); ApplicationInfo ai = pm.getApplicationInfo(runningPkg , 0); 

Added:

If you are not getting the apk name then you can compare it with intalled pkg and get the corresponding app name. You can fetch the installed app's pkg name and app name like this:

ArrayList<PackageInfo> res = new ArrayList<PackageInfo>(); PackageManager pm = ctx.getPackageManager(); List<PackageInfo> packs = pm.getInstalledPackages(0); for(int i=0;i<packs.size();i++) { PackageInfo p = packs.get(i); String description = (String) p.applicationInfo.loadDescription(pm); String label= p.applicationInfo.loadLabel(pm).toString(); //Continue to extract other info about the app... } 

Note: Add this permission to the manifest file:

<uses-permission android:name="android.permission.GET_TASKS" /> 

This is achieved with getPackageArchiveInfo from an already packaged apk file:

 PackageInfo package_info = pm.getPackageArchiveInfo(file_path_to_apk, 0); 

Try this it work for me:

String versionName = "null"; //String apk versionName int versionCode = -1; //int versionCode String APKFilePath = "/storage/emulated/0/apkname.apk"; //For example PackageManager pm = getPackageManager(); PackageInfo packageInfo = pm.getPackageArchiveInfo(APKFilePath, 0); // the secret are these two lines packageInfo.applicationInfo.sourceDir = APKFilePath; packageInfo.applicationInfo.publicSourceDir = APKFilePath; Drawable APKicon = packageInfo.applicationInfo.loadIcon(pm); //drawable apk icon String AppName = (String)packageInfo.applicationInfo.loadLabel(pm); // String apk name versionName = packageInfo.versionName; //String version name versionCode = packageInfo.versionCode; //int version code apk_icon.setImageDrawable(APKicon); //ImageView apk icon Apkpackage.setText(packageInfo.packageName); //TextView apk package name Apkname.setText(AppName); //TextView apk name Apkversion.setText(String.format("Version Name: %s Version Code:%d", versionName, versionCode)); //TextView versionName and versionCode
