Building a simple apk for testing

In order to build a rough test application quickly, start from a “made-by-default” apk from the

usual building tools (ADT/Eclipse,…), and modify the following:

STEP 1:

/res/layout/activity_main.xml

Android sample apk: activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

<TextView

android:id="@+id/TextView01"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="Humidity Info">

</TextView>

</LinearLayout>

STEP 2:

/src/com.example.com.MainActivity.java

package com.example.<ProjectName>

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.ViewGroup.LayoutParams;

import java.io.IOException;

import java.io.InputStream;

import android.annotation.SuppressLint;

import android.hardware.Sensor;

import android.hardware.SensorEvent;

import android.hardware.SensorEventListener;

import android.hardware.SensorManager;

import android.util.Log;

import android.view.View;

import android.widget.Button;

import android.widget.TextView;
