I am been trying to copy a apk from assets of another apk to /system.

Here is what I have done,it was working in my previous app but not in this.I have added permission for wrtiting external storage. It is successfully copying to internal storage,not not to /system. Is there any way to directly copy to /system?

copyStream("y.apk","/sdcard/x.apk");

Process mSuProcess;

mSuProcess = Runtime.getRuntime().exec("su");

new DataOutputStream(mSuProcess.getOutputStream()).writeBytes("mount -o remount rw /system");

DataOutputStream mSuDataOutputStream = new DataOutputStream(mSuProcess.getOutputStream());

mSuDataOutputStream.writeBytes("cp /sdcard/x.apk /system/app/x.apk"); 

mSuDataOutputStream.writeBytes("exit\n");

Did you forget the newlines on your other commands? – nneonneo Oct 07 '12 at 03:35
Thank you,it solved.Any way to directly copy it to /system? – Neal Oct 07 '12 at 03:58
Not without some invocation of `su`, unfortunately. – nneonneo Oct 07 '12 at 04:04
Does `cp y.apk /system/app/x.apk` not work? – nneonneo Oct 07 '12 at 06:15
Well,actually y.apk is in asset folder of an app,so by using copyStream,it will be copied to sdcard,then using cp to /system,. – Neal Oct 07 '12 at 06:18
Oh yes, that's right. Sorry, then you will have to copy the file somewhere since the assets folder is not on disk anywhere (it is in the compressed application file). – nneonneo Oct 07 '12 at 06:22
