24.判斷是否有root權限
[java] view plaincopyprint?
public static synchronized boolean getRootAhth()
{
Process process = null;
DataOutputStream os = null;
try
{
process = Runtime.getRuntime().exec(su);
os = new DataOutputStream(process.getOutputStream());
os.writeBytes(exitn);
os.flush();
int exitValue = process.waitFor();
if (exitValue == 0)
{
return true;
} else
{
return false;
}
} catch (Exception e)
{
Log.d(*** DEBUG ***, Unexpected error - Here is what I know:
+ e.getMessage());
return false;
} finally
{
try
{
if (os != null)
{
os.close();
}
process.destroy();
} catch (Exception e)
{
e.printStackTrace();
}
}
}
25.最簡單的Root 模擬器的方法
啟動一個模擬器，開始-運行-輸入cmd，打開dos，依次輸入
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/bin
cat sh > su
chmod 4755 su
su
即可獲得root權限
