What Challenges Arise with Directory Creation in Android Marshmallow?

Android Marshmallow: Challenges with Directory Creation

While creating directories in native applications is typically straightforward in Android 5.0, users may encounter intermittent issues in Android 6.0 (Marshmallow). This inconsistency poses a challenge for developers who create and store files in specific directories.

The challenge arises from the fact that Android Marshmallow introduced stricter permissions for external storage. These permissions require explicit approval from the user before applications can access external storage.

To address this issue, it is essential to request runtime permissions before attempting to create directories in external storage. The following code illustrates how to request runtime permissions in Android Marshmallow:

<code class="java">@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (CheckPermission(MyDevIDS.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
        // you have permission go ahead
        createApplicationFolder();
    } else {
        // you do not have permission go request runtime permissions
        RequestPermission(MyDevIDS.this, Manifest.permission.WRITE_EXTERNAL_STORAGE, REQUEST_RUNTIME_PERMISSION);
    }
}

...</code>

In this code:

• CheckPermission method checks for the наличии of the WRITE_EXTERNAL_STORAGE permission.
• RequestPermission method requests the WRITE_EXTERNAL_STORAGE permission.
• createApplicationFolder method creates the necessary directories after obtaining permission.

By requesting runtime permissions, you ensure that your application has the necessary permissions to create directories and store files in the desired location. This approach ensures the consistent operation of directory creation in both Android 5.0 and Android Marshmallow.
