How to copy file using adb to android directory accessible from PC

Question

If you attach android device to PC you can browse files and dirs. It is possible to get this directory using Environment.getExternalStorage(). You can use it from your application and create accessible files and dirs. It works fine.

On my devices this path looks like /storage/emulated/0 and if i try adb push to this directory i will get access denied error. Is it possible to copy files using adb to the same folder as Windows Explorer does?

D:\...\tools>adb push ACCOUNTS.DB /storage/emulated/0
failed to copy 'ACCOUNTS.DB' to '/storage/emulated/0': Permission denied
58969 KB/s (606505 bytes in 0.010s)

I'm implementing automated import/export and i want files to be accessible without adb shell in case anything will go wrong.

Currently using variable$EXTERNAL_STORAGE as workaround, it works for both adb and application.

Device: Asus Fonepad 7, Android 5.0, tried Genymotion Custom Tablet 6.0 - works.

Answer 1

Try to use /sdcard/. Although it is strongly discouraged to do this in code. It seems to be the only way with adb :

$ adb push somefile /storage/emulated/0/somefile
[100%] /storage/emulated/0/somefile
adb: error: failed to copy 'somefile' to '/storage/emulated/0/somefile': Read-only file system

$ adb push somefile /sdcard/somefile
[100%] /sdcard/somefile

By the way, on my device they don't have the same value : Environment.getExternalStorage() points to /storage/emulated/0/ while /sdcard points to /storage/emulated/legacy.

Answer 2

It's pretty easy, internal storage is unavailable on non-rooted devices. So as was mentioned in bwt answer you just need to push your data to sdcard :

adb push somefile /sdcard/somefile

With retrieving files from your filesystem you'll also have few problems. But with the case of pulling a database from a debug application - you'll just need to change file permission via chmod. Here you have a useful link - XDA guys about adb
