install apk in background using busybox

问题

can i install apk in background using busybox on rooted device ???

i see something like that but it doesn't work

process install;
CommandCapture command = new CommandCapture(0, "chmod 777 /data/app");
RootTools.getShell(true).add(command).waitForFinish(); 
CommandCapture command2 = new CommandCapture(0, "chmod 777 /system/xbin/busybox");
RootTools.getShell(true).add(command2).waitForFinish();
install = Runtime.getRuntime().exec("/system/xbin/busybox install " + Environment.getExternalStorageDirectory() + "/Download/" + "xxx.apk /data/app/xxx.apk");

回答1:

If you run su -c pm install myapp.apk in a root shell, you should be able install in the background (note the 'pm') part. This has nothing to do with busybox, you can use any shell and you certainly don't need to change permission of /data/app.

回答2:

without using busybox

install = Runtime.getRuntime().exec("su");   
DataOutputStream os = new DataOutputStream(install.getOutputStream());  
os.writeBytes("pm install "+APKFile.apk+"\n");  
os.writeBytes("exit\n"); 
os.flush();
install.waitFor();

It looks you use two paths for your busybox binary. First you chmod it in /system/xbin, but then you invoke it from system/bin. Ensure you use right path. And chmod 777 /data/app looks VERY BAD.
