Question

I have a routed device and when I do this

adb shell  cat /data/misc/bluetooth/dynamic_auto_pairing.conf

it prints the content of this file.

But in my code when I write something like this, it says that the file does not exist. Well from the console I see it I know is there, but from code I can’t read it. My question is what is the problem , am I missing some permission or what is the problem ? can someone provide me with some code to read the content from this file.

Thanks

File pa = new File("/data/misc/bluetooth/","dynamic_auto_pairing.conf");
//this doesn't works also
//File pa = new File("/data/misc/bluetooth","dynamic_auto_pairing.conf");
//File pa = new File("/data/misc/bluetooth/dynamic_auto_pairing.conf");
if(pa.exists()){
    Log.v("tag", "does exists");
}else{
    Log.v("tag", "does NOT exist");
}

If the file is on sdcard, try:

File pa = new File(Environment.getExternalStorageDirectory() + "/data/misc/bluetooth/dynamic_auto_pairing.conf");

Also try to add:

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

outside <application></application> in your manifest file.

EDIT
If the file is in internal memory: Your app can read only from a special folder in internal memory. The path to that folder is returned by:
getFilesDir().getAbsolutePath()

So put the file there and read it with openFileInput().
