Saya baru mengenal pengembangan Android dan saya ingin Hello World
menjalankan aplikasi terlebih dahulu. Saya menggunakan Eclipse IDE dan Android 4.0.3 versi 15 SDK. Saya menyalin semuanya dari situs tutorial, tetapi ketika saya mencoba menjalankan aplikasi di virtual device
saya mendapatkan kesalahan ini:
[2012-02-01 11:31:23 - Android_test] Installation error: INSTALL_FAILED_OLDER_SDK
[2012-02-01 11:31:23 - Android_test] Please check logcat output for more details.
[2012-02-01 11:31:23 - Android_test] Launch canceled!
Ini kelas saya dalam com.maze.app
paket: package com.maze.app;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HelloAndroid extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText("Hello, Android");
setContentView(tv);
}
}
dan AndroidManifest.xml
:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.maze.app"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="@string/app_name"/>
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity android:name="HelloAndroid" android:launchMode="standard" android:enabled="true"></activity>
</application>
Berikut konfigurasi dari Virtual Device
:
Name: AndroidVD
CPU/ABI: ARM(armeabi-v7a)
Path: path\to\avd
Target: Android 4.0.3(API level 15)
Skin: WVGA800
hw.lcd.density: 240
hw.cpu.model: cortex-a8
vm.heapSize: 48
hw.ramSize:512
What is the problem?
EDIT: The application is not running on the Virtual Device: Here is what I get on LogCat(some of the lines):
D/PackageManager(92): New package installed in /data/app/com.maze.app-2.apk
