Program ever perform su this command, there must be some difference, because I have to use the su command in your program, and I play a mobile game is suggested I use the auxiliary, but actually I didn't, I repeated test, the original is my this contains the su command program, after I shielding su this line of code, the game is not prompt, I don't understand is that how to check the game

 public static Boolean upgradeRootPermission (String pkgCodePath) {
Process Process=null; 
DataOutputStream OS=null; 
Boolean resBoolean; 
Try {
String CMD="chmod 777 + pkgCodePath"; 
The process=Runtime. GetRuntime (). The exec (" su ");//switch to the root account 
OS=new DataOutputStream (process. GetOutputStream ()); 
OS. WriteBytes (CMD + "\ n"); 
OS. WriteBytes (" exit \ n ");//withdraw from the root account, will not perform sticking machine 
OS. The flush (); 
ResBoolean=process. WaitFor ()==0; 
} the catch (Exception e) {
return false; 
} the finally {
Try {
If (OS!=null) {
OS. The close (); 
} 
Process. The destroy (); 
} the catch (Exception e) {
} 
} 
Return resBoolean; 
}

PkgCodePath is a package name, all the app install detection, look have root access app.
