android - /storage/emulated/0 obtained from getExternalCacheDir() generates "no such file or directory" error -

running on nexus 4, when phone call getexternalcachedir().getabsolutepath() path /storage/emulated/0/android/data/com.example.myapp/cache. problem that, stated in different places, /storage/emulated/0 generate "no such file or directory" error.

what expect /storage/emulated/legacy, correctly querying external_storage environment variable commands system.getenv("external_storage").

i utilize if statement check , right path in case point different getenv, want understand why getexternalcachedir() returns invalid path, or if function has been deprecated somehow.

additional notes: on xperia u running cm11 works fine; targetting nexus 4 adb get

ls /storage/emulated/0 /storage/emulated/0: no such file or directory

i've proper access permissions, since if call, example, echo "hi!" >> /storage/emulated/legacy/android/data/com.example.myapp/cache have no clues, while calling echo "hi!" >> /storage/emulated/0/android/data/com.example.myapp/cache results in errors. latter getexternalcachedir.

i'm interested in using path shell commands, not android api functions.

getexternalcachedir gives valid path. can read/write given external storage mounted , have proper access permissions.

that :

if (media_mounted.equals(environment.getexternalstoragestate()) // mounted && context.checkcallingorselfpermission("android.permission.write_external_storage") == packagemanager.permission_granted) { // have permissions file mytempdir = new file(getexternalcachedir(), "tempdir"); mytempdir.mkdirs(); // create , write files }

hope helps.
