私は素敵なクラスを修正することができました。

// PHONE STORAGE 
public static long phone_storage_free(){ 
    File path = Environment.getDataDirectory(); 
    StatFs stat = new StatFs(path.getPath()); 
    long free_memory = stat.getAvailableBlocks() * stat.getBlockSize(); //return value is in bytes 

    return free_memory; 
} 

public static long phone_storage_used(){ 
    File path = Environment.getDataDirectory(); 
    StatFs stat = new StatFs(path.getPath()); 
    long free_memory = (stat.getBlockCount() - stat.getAvailableBlocks()) * stat.getBlockSize(); //return value is in bytes 

    return free_memory; 
} 

public static long phone_storage_total(){ 
    File path = Environment.getDataDirectory(); 
    StatFs stat = new StatFs(path.getPath()); 
    long free_memory = stat.getBlockCount() * stat.getBlockSize(); //return value is in bytes 

    return free_memory; 
} 

// SD CARD 
public static long sd_card_free(){ 

    File path = Environment.getExternalStorageDirectory(); 
    StatFs stat = new StatFs(path.getPath()); 
    long free_memory = stat.getAvailableBlocks() * stat.getBlockSize(); //return value is in bytes 

    return free_memory; 
} 
public static long sd_card_used(){ 

    File path = Environment.getExternalStorageDirectory(); 
    StatFs stat = new StatFs(path.getPath()); 
    long free_memory = (stat.getBlockCount() - stat.getAvailableBlocks()) * stat.getBlockSize(); //return value is in bytes 

    return free_memory; 
}

    File path = Environment.getExternalStorageDirectory();

    return free_memory;
