Check if the SDCard is present, boolean is always true
android, android-sdcard, splash-screen
Solution
I've found that phones, like the Galaxy phones from Samsung, have `/mnt/sdcard` point to internal memory and not the external SD card as expected.
You can know if the path returned by Environment.getExternalStorageDirectory() is actually the external SD card with a call to Environment.isExternalStorageRemovable()
Just wanted to add from the docs for getExternalStorageDirectory() this important note:
Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.
Problem
In my splash screen, I want to check if the phone has a SDCard. The Boolean statement is beneath: ``` Boolean isSDPresent = android.os.Environment.getExternalStorageState() .equals(android.os.Environment.MEDIA_MOUNTED ); ``` So, if I have the SDCard in the slot on my phone, this boolean will return true, so far so good. When I go to the "Unmount SDCard" from the settings menu, and removes the SDCard, then kill the app and launching it again, the boolean will also be true.. And if I launches the `Astro File Manager` after unmounting and removing the sdcard, I can still access the `/mnt/sdcard` path, why? How can I manage to accomplish this? Thanks in advance! EDIT Testing with the following code: ``` File path = Environment.getExternalStorageDirectory(); String pathS = path.getPath(); ``` When the SDCard is in the slot, the `pathS` contains `mnt/sdcard`, but when I removes the SDCard the `pathS` is still `/mnt/sdcard` ...
