Problems playing music stored on sdcard

Hi, is anyone else experiencing issues with playing music stored on their sdcard? The music plays for several minutes and then will just pause for no apparent reason. No sign that the card has been unmounted or anything like that, could it be a problem with the card itself perhaps although I've copied lots of music to and from it with no problems?

Thanks

SDcard options with Root?

I have a Galaxy S5 on Sprint's network which is currently not rooted and completely stock. Problem is the storage on the phone is only 16GB which can be quite limiting at times. I know I can move some applications to the SD card however even when moving the applications it leaves a chunk of the program on the internal storage plus any app upgrade gets installed on the internal flash not the SD card.

What I'm hoping to do is
1) keep the stock software (possibly remove some of the bloatware)
2) use the microSD card for all applications instead of the internal flash (I have a class 10 64GB MicroSD card)
3) retain use of google pay (I think this can be done with root blockers/hiders?)

So is the above possible? How would I go about doing the above?

If I do root the phone I believe the phone will then indicate that its been tampered with (Knox?) can this indicator later be reversed? reinstalling the original Samsung software, or is this a permanent side effect of rooting?

Thanks,

Safing ROM on sdcard

Hey,

I've installed TWRP on my S6 and wiped my device but then I realized that I forgot to safe the custom ROM on the sdcard.
Is there a possibility to safe it on the sdcard without a system on it?

Forcing external sdcard on android with cordova and file plugin - Galaxy tab 10.5

In a cordova android app (scroll to the bottom for device,version, plugin list, all of it quite up-to-date as of this writing) I want to preferentially store file on the external SDCard and use internal storage if SDCard not there. I am setting my save path to:

persistentFS= cordova.file.externalDataDirectory||cordova.file.D ataDirectory||fileSystem.root.toURL();

Its eventual value is file:///storage/emulated/0/Android/data/com.fubar.app/files/, same as cordova.file.externalDataDirectory.

I have set:
<access origin="cdvfile://*" />
...
<preference name="AndroidPersistentFileLocation" value="Compatibility" />
<preference name="AndroidExtraFilesystems" value="files-external,sdcard,files,documents,cache,cache-external,root" />

in config.xml,

<uses-permission android:name="android.permission.WRITE_EXTERNAL_ST ORAGE" />

in AndroidManifest.xml and set various enchantments in index.html Security metatag. I add that a SDcard is inserted, write-enabled and I confirm that I can write to it with - for example - a file manger. It contains the Android/data/com.fubar.myapp/files/ folder, as it should.

All for nothing: files get written to - and read from - the internal device storage. I have read all google could scavenge on this topic but nothing has brought me closer to the task (some folks suggest using the file-system-roots plugin, but it appears to have been subsumed by the file plugin).

Using adb shell, I can see that the external sdcard files folder for the app has an absolute path of:

/storage/extSdCard/Android/data/com.fubar.myapp/files

and calling resolveLocalFileSystemURL on

file:///storage/extSdCard/Android/data/com.fubar.myapp/files

happily succeeds. I do not think that is the way to go, as that path is device dependent.

Any hints? TIA, alf

Mount or unmount a sdcard

Hello. My phone is xperia z1 and I wanna unmount my sdcard that has been inserted in the phone via an app,terminal emulator or other option. Note: I dont want to eject the sdcard from the phone physically just I wanna unmount it by keeping inside the phone. Also, I wanna mount it, whenever I need my sdcard to read or write something.
Xperia z1 has an option to unmount or mount a sdcard from the phone but after restarting the phone, the sdcard is mounted automatically by the phone but I dont want this. I wanna control it manually whenever I want.

How can I do it? It is very important. Please, tell me an exact way to do it.

Regards,
Sarkhan
