there file called mainactivity.java has nothing inside except default stuff, , there xml file called main_activity.xml has nothing inside it.

here andoidmanifest.xml:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.qosmetre2" android:versioncode="1" android:versionname="1.0" >  <uses-sdk     android:minsdkversion="11"     android:targetsdkversion="17" />  <application     android:allowbackup="true"     android:icon="@drawable/ic_launcher"     android:label="@string/app_name"     android:theme="@style/apptheme" >     <activity         android:name="com.example.qosmetre2.mainactivity"         android:label="@string/app_name" >         <intent-filter>             <action android:name="android.intent.action.main" />              <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>      <activity         android:name=".mysqldata"         android:label="all data" >      </activity>   </application> 

if both devices on same network, , you'll using app when @ home/connected same network, can use local ip address assigned computer router, 192.168.1.4

if you're going want use app on 3g/4g or wifi connection away computer, you'll need edit routers port forwarding settings , you'll connect using router's ip address. can register free domain name connected ip address won't have remember bunch of numbers.

this not coding issue though...
