Find SQLite database on Android

The reason why sub-directories do not appear in the Data folder is adb not having permissions to read its content.

Use the Device File Explorer .

You can open it through View > Windows Tool > Device File Explorer or by clicking the button in the lower right side of Android Studio.

You can interact with the content by right-clicking to create a new one, saving the selected file or folder on the pc, deleting or synchronizing.

Notes:

• Requires Android Studio 3.0 or higher
• The content of the Data folder is only visible if the device is an emulator.

If you can not find the file through the "Device File Explorer" window, you can use the following code:

try {

    /* Captura o arquivo original */
    File src = new File(Environment.getDataDirectory(), "//data//".concat(getPackageName()).concat("//databases//SEU-BANCO.db"));

    /* Captura o caminho do arquivo de destino */
    File dst = new File(Environment.getExternalStorageDirectory().getPath().concat("/SEU-BANCO-BACKUP.db"));

    /* Cria o arquivo de destino */
    dst.createNewFile();

    /* Abre o arquivo original e o de destino para leitura e escrita, respectivamente */
    FileInputStream inputStream = new FileInputStream(src);
    FileOutputStream outputStream = new FileOutputStream(dst);
    int b = 0;

    /* Ler o conteúdo em byte do arquivo original e escreve no arquivo de destino */
    while ((b = inputStream.read()) != -1) {
        outputStream.write(b);
    }

    /* Fecha as conexões */
    outputStream.close();
    inputStream.close();
} catch (Exception e) {
    e.printStackTrace();
}
