Question

How can you retrieve your phone internal storage from an app? I found MemoryInfo, but it seems that returns information on how much memory use your currently running tasks.

I am trying to get my app to retrieve how much internal phone storage is available.

Answer 1

Use android.os.Environment to find the internal directory, then use android.os.StatFs to call the Unix statfs system call on it. Shamelessly stolen from the Android settings app:

File path = Environment.getDataDirectory();
StatFs stat = new StatFs(path.getPath());
long blockSize = stat.getBlockSize();
long availableBlocks = stat.getAvailableBlocks();
return Formatter.formatFileSize(this, availableBlocks * blockSize);
