这是我的code

final Context context = this;
TextView textServer, textApp;
final String textSource = "http://xxx/dev/android/androidversi.txt";

声明位置的.txt文件的

DECLARATION FOR LOCATION OF .txt file

URL textUrl;
String StringBuffer;
String stringText = "";

try {
    textUrl = new URL(textSource);
    BufferedReader bufferReader = new BufferedReader(new InputStreamReader(textUrl.openStream()));

    while ((StringBuffer = bufferReader.readLine()) != null) 
    {
        stringText += StringBuffer;
    }
    bufferReader.close();
} catch (MalformedURLException e) {
    // TODO Auto-generated catch block

PackageManager manager = getPackageManager();
PackageInfo info;

    int version = info.versionCode;

    if(Integer.parseInt(stringText)>version) // I'VE CONVERTED STRING FROM .txt TO INT SO THAT I CAN COMPARE IT WITH VERSION ON APP
    {
        // IF VERSION ON SERVER > VERSION APP THERE IS LINK TO DOWNLOAD HERE
    }
} catch (NameNotFoundException e){
    e.printStackTrace();
}

推荐答案

它不过是网络上的主线程除外;只是包括

Its nothing but the Network on main thread exception; Just include

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
}

到code（在onCreate（）方法），你会被罚款：）

to your code (in onCreate() method) and you'll be fine :)
