测试:

void rootShell(){
		String[] str={"adb shell","adb get-product","adb get-serialno"};
		CommandResult rs=ShellUtils.execCommand(str, true);
		
		Toast.makeText(MainActivity.this, "-msg:-"+rs.successMsg+"-rs-"+rs.result+"-error-"+rs.errorMsg, 0).show();
		System.out.println("-msg:-"+rs.successMsg+"-rs-"+rs.result+"-error-"+rs.errorMsg);
