Android app request to get Root permission

To grant the Root permission to the Android app, the Android device must have the Root permission.

How an application obtains Root permissions: grant the highest permissions to the Code Execution directory of the application. In Linux, chmod 777

[Code] java code:

/**

* If the application runs the command to obtain the Root permission, the device must be cracked (obtain the ROOT permission)

*

* @ Return application Yes/No get Root permission

*/

Public static boolean upgradeRootPermission (String pkgCodePath ){

Process process = null;

DataOutputStream OS = null;

Try {

String cmd = "chmod 777" + pkgCodePath;

Process = runtime.getruntime(cmd.exe c ("su"); // switch to the root account

OS = new DataOutputStream (process. getOutputStream ());

OS. writeBytes (cmd + "\ n ");

OS. writeBytes ("exit \ n ");

OS. flush ();

Process. waitFor ();

} Catch (Exception e ){

Return false;

} Finally {

Try {

If (OS! = Null ){

OS. close ();

}

Process. destroy ();

} Catch (Exception e ){

}

}

Return true;

}

Call code:

[Code] java code:

@ Override

Public void onCreate (Bundle savedInstanceState ){

Super. onCreate (savedInstanceState );

SetContentView (R. layout. main );

// Code execution directory of the current application

UpgradeRootPermission (getPackageCodePath ());

}

After executing the above Code, the system will pop up the dialog box "whether to allow the Root permission to be obtained". Then, select allow.
