StorageUtil

Easily get all available external storage paths in an Android device.

Important Note

If your minimal SDK version is 19, consider using Storage Access Framework instead to get file from the device.

Don't be confused with external storage term here. The Internal and External Storage terminology according to Google/official Android docs is quite different from what we think.

According to official Android docs:

Internal Storage: By default, files saved to the internal storage are private to your application and other applications cannot access them. When the user uninstalls your application, these files are removed/deleted. Your app user also can't access them using file manager; even after enabling "show hidden files" option in file manager. To access files in Internal Storage, you have to root your Android phone. So, this is NOT what we think as internal memory of the phone - Nexus 5's 32 GB internal memory.

External Storage:

This can be a removable storage media (such as an SD card) or an internal (non-removable) storage

That means, both storage types like Nexus 6P's 64 GB internal memory and removable microSD card which we insert in phone's card slot are considered as External Storage.

Removable Storage means just microSD card storage, not the internal memory.

How to

• Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

• Add the dependency (see the latest version from the jitpack badge or Release)

dependencies {
    implementation 'com.github.hendrawd:StorageUtil:x.x.x'
}

• Get the external storage paths

String[] externalStoragePaths = StorageUtil.getStorageDirectories(context);
// do whatever you want with the externalStoragePaths
