Pick a file using Intent.ACTION_GET_CONTENT

This tutorial is tested on Honeycomb 3.0 environment. In order to be used it in the lower level of Android API, I believe you could just change the target in the Android project.

Pick an image file using Intent.ACTION_GET_CONTENT

The intention of this project is to choose an image file available in the device storage, and simply display it in an ImageView. The benefit of using Intent.ACTION_GET_CONTENT is you don’t have to develop open dialog box which is not available in the Android library.

ACTION_GET_CONTENT with MIME type */* and category CATEGORY_OPENABLE -- Display all pickers for data that can be opened with ContentResolver.openInputStream(), allowing the user to pick one of them and then some data inside of it and returning the resulting URI to the caller. This can be used, for example, image chooser (as shown in this article).

LAYOUT: main.xml

<?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" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#0000ff"
android:text=" " />

<Button
android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Choose image using Intent.ACTION_GET_CONTENT" />


<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" />

</LinearLayout>

Most used STRING functions in my PHP coding

These are my favourite string manipulation functions in my daily coding life. Dedicated especially to Web Programming students. Read them and have fun. Expect a happiness after a storm , and you’ll find your “inner peace”… This post is still in draft. I’ll update and refine with more examples that I’ve personally develop. More after the break…
