Hi Dianne ,
How can i add uses-permisson to an apk.If i need to acees /dev/mem using an
native interface.
I will put my problem in 2 steps.
1) I am trying to control I/O using an apk with the help of native
method(JNI).In my native method I am trying to open /dev/mem and mmaping
the i/o address.
But native code fails in opening /dev/mem. I have explicitly installed apk
in system/apk on a remounted file system.
2) If i run a linux executable on the same android machine it works.
So is there any way to run this apk as root by adding permission in
manifest file.I have tried changing permission for dev/mem in apk itself(no
success)
String command = String.format("chmod 777 /dev/mem");
try {
p = Runtime.getRuntime().exec(new String[] {"su", "-c",
command});
.............
Regards,
Govind
