安卓root修改时间源码

安卓root修改时间源码 无需布局，无需界面，只需root权限和将下面的源码拷进main（activity）就可以了！更多问题加QQ:1041855398。 public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); try { upgradeRootPermission(); SimpleDateFormat s=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); if(SystemClock.setCurrentTimeMillis(s.parse("2015-1-1 00:00:00").getTime())){ Toast.makeText(this, "修改时间成功", Toast.LENGTH_SHORT).show(); }else{ Toast.makeText(this, "修改时间失败！", Toast.LENGTH_SHORT).show(); } } catch (Exception e) { Toast.makeText(this, "修改时间失败！", Toast.LENGTH_SHORT).show(); } } public boolean upgradeRootPermission() { Process process = null; DataOutputStream os = null; try { SimpleDateFormat s=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); long l= s.parse("2018-02-12 14:01:00").getTime(); String cmd = "date "+(l/1000); process = Runtime.getRuntime().exec("su"); // 切换到root帐号 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(); } if (process != null) { process.destroy(); } } catch (Exception e) { return false; } } return true; } }
