最近学习Android的时候写个小程序需要用到获取ROOT权限,在网上找了好久,发现这种方法可行,前提时设备必须已经破解过!能执行su命令。
一、建一个方法:代码如下:
View Code
package cn.ycmoon.utility;
import java.io.DataOutputStream;
import android.app.Activity;
import android.util.Log;
public class SystemManager extends Activity
{
/**
* 应用程序运行命令获取 Root权限,设备必须已破解(获得ROOT权限)
* @param command 命令:String apkRoot="chmod 777 "+getPackageCodePath(); RootCommand(apkRoot);
* @return 应用程序是/否获取Root权限
*/
public static boolean RootCommand(String command)
{
Process process = null;
DataOutputStream os = null;
try
{
process = Runtime.getRuntime().exec("su");
os = new DataOutputStream(process.getOutputStream());
os.writeBytes(command + "\n");
os.writeBytes("exit\n");
os.flush();
process.waitFor();
} catch (Exception e)
{
Log.d("*** DEBUG ***", "ROOT REE" + e.getMessage());
return false;
} finally
{
try
{
if (os != null)
{
os.close();
}
process.destroy();
} catch (Exception e)
{
}
}
Log.d("*** DEBUG ***", "Root SUC ");
return true;
}
}
import java.io.DataOutputStream;
import android.app.Activity;
import android.util.Log;
public class SystemManager extends Activity
{
/**
* 应用程序运行命令获取 Root权限,设备必须已破解(获得ROOT权限)
* @param command 命令:String apkRoot="chmod 777 "+getPackageCodePath(); RootCommand(apkRoot);
* @return 应用程序是/否获取Root权限
*/
public static boolean RootCommand(String command)
{
Process process = null;
DataOutputStream os = null;
try
{
process = Runtime.getRuntime().exec("su");
os = new DataOutputStream(process.getOutputStream());
os.writeBytes(command + "\n");
os.writeBytes("exit\n");
os.flush();
process.waitFor();
} catch (Exception e)
{
Log.d("*** DEBUG ***", "ROOT REE" + e.getMessage());
return false;
} finally
{
try
{
if (os != null)
{
os.close();
}
process.destroy();
} catch (Exception e)
{
}
}
Log.d("*** DEBUG ***", "Root SUC ");
return true;
}
}
二、在应用程序的MainActivity方法中:
public class MainActivity extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String apkRoot="chmod 777 "+getPackageCodePath();
SystemManager.RootCommand(apkRoot);
}
}
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String apkRoot="chmod 777 "+getPackageCodePath();
SystemManager.RootCommand(apkRoot);
}
}
这样,在应用程序运行的时候,会弹出消息对话框“应用程序已获取root权限”
