ShellAndroid

A shell for android. Can execute most linux shell command in it. You can easy to get last command result. At most time, it like a lite terminal, you can keep global shell in your application.

sh --> su --> id
the last result: uid=0(root) gid=0(root)

and then

exit --> id
the last result: uid=10103(u0_a103) gid=10103(u0_a103) groups=1028(sdcard_r)

A exact result of last command got from the ShellAndroid.

How to use

• If not use ShellAndroid.initFlagMinimum(context), 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()); // not suggest to use this for most device
    String flagFile = mShell.initFlagMinimum(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 onDestroy 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.

• Get command result by getLastResult() in ShellAndroid.(more details are in example)

    mShell.exec(false, "cd /sdcard");
    mShell.exec(false, "pwd");
    mShell.getLastResult(); // pwd result, return "/sdcard"
    
  

• 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.
