How to get access to external storage since environment.getexternalstoragedirectory() is deprecated

Question

I am new in android and I want to read all the files from external storage in order to make a file explorer app but I can't find a way to access those files. What should I use instead of environment.getexternalstoragedirectory()?

Answer 1

Use getExternalFilesDir() , getExternalCacheDir() , getExternalMediaDir () ... Read more .

For example ( getExternalFilesDir ) :

public static File getAppFileDir(Context context) {
    File file;
    if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        file = context.getExternalFilesDir(null);
    } else {
        file = context.getFilesDir();
    }
    return file;
}

will give you:

android/data/data/your_package_name/files

If you still want to use getExternalStorageDirectory :

public static File getExternalStorageDirectory(Context context) {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.Q) {
        //noinspection deprecation
        return Environment.getExternalStorageDirectory();
    } else {
        try {
            File file = getAppFileDir(context);
            if (null != file) {
                //noinspection ConstantConditions
                return file.getParentFile().getParentFile().getParentFile().getParentFile();
            } else {
                return new File("");
            }
        } catch (Throwable e) {
            e.printStackTrace();
            return new File("");
        }
    }
}

But don't use it in a release app, cause I'm not sure if it will work on all devices.
