How to use

• Put the cflag executable file to assets in your project.

• Initialize the ShellAndroid.(see mainActivity.java in example)

    //---- shell initialization ----
    mShell = new ShellAndroid();
    String flagFile = mShell.initFlag(getApplicationContext());
    mShell.printOutput();
    mShell.setFlagFile(flagFile);
    //---- finish shell initialization ----
  

• Close the ShellAndroid if you never need it.(like the example close the shell on the onDestory method in activity)

    protected void onDestroy() {
    	// TODO Auto-generated method stub
    	super.onDestroy();
    	if (mShell != null){
    		mShell.close();
    	}
    }
  

• Execute shell command in a work thread.

• If you want get root permission, the best way is use the shell methods.

    shell.checkRoot()	// try to get root permission
    shell.hasRoot()	// Is it the root user now
    shell.exitRoot()	// exit root user, even if you execute su command many times.
