Android parses the APK file on the SD card public void parseApk(Context context, String apkFilePath){ PackageManager packageManager = context.getPackageManager(); PackageInfo packageInfo = packageManager.getPackageArchiveInfo(apkFilePath, 0); if(packageInfo != null){ packageInfo.applicationInfo.sourceDir = apkFilePath; packageInfo.applicationInfo.publicSourceDir = apkFilePath;

The Android program function Copies files in the assets folder to the SD card (including subfolders) of the mobile phone and androidassets.
