This is amazing to know we can run keytool via ADB and Dalvikvm, But..

[rupeshkumar22]

How can I run this in my android app. There's a process builder runtime.exec() command to run arm binaries or system binaries in android. But ADB and Dalvik can only be run if root permission is accessed if I am not wrong. Any chances to use the keytool or this keytool.dex file inside the android app programmatically? Thanks!

Sorry, I'm late.
I think there are two options for that, as follows

(1) Instead of creating a single dex for the keytool, create an Activity as usual, link this program to it, and execute the code such as the following from within the Activity --

String[] args = xxx;
sun.security.tools.KeyTool.main( args );
.

(2) If you want to run dalvikvm in your androind device, write shellscript xxx.sh as the following :
[/sdcard/xxx.sh]
dalvikvm some parametres for dalvikvm

and execute java code in your activity :
String[] commands = { "sh", "/sdcard/xxx.sh" };
ProcessBuilder builder = new ProcessBuilder( commands );

Thanks.
