Akhirnya client android socket selesai juga kita buat. Untuk membuat aplikasi client android socket, berikut langkah-langkahnya:
Pertama buat “Android Application Project” di android studio atau di eclipse with adt. Beri nama projectnya “Socket Client”.
Kedua buka file “AndroidManifest.xml”, lalu tambahkan syntax:
|
1 2 3 |
<uses-permission android:name="android.permission.INTERNET" > </uses-permission> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" ></uses-permission> |
Penampakan full file “AndroidManifest.xml”
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.socketclient" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="11" android:targetSdkVersion="21" /> <uses-permission android:name="android.permission.INTERNET" > </uses-permission> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" > </uses-permission> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".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> </application> </manifest> |
Ketiga buka file “activity_main.xml” di folder “res/layout”, lalu modifikasi seperti syntax dibawah ini:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <EditText android:id="@+id/editText01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="" > </EditText> <Button android:id="@+id/myButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="onClick" android:text="Send" > </Button> <TextView android:id="@+id/textView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="" /> </LinearLayout> |
Terakhir adalah kita modifikasi file “MainActivity.java”, untuk modifikasi file ini jangan asal copy paste semua syntax dibawah ini ke file “MainActivity.java”. Berikut syntax fullnya:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 |
