Good Day Internet!
I am trying to retrieve and display an image from mysql database into an image view (android). The image is a blob type. I have the following php code that gets the image from mysql.
<?php
error_reporting(E_ALL ^ E_DEPRECATED);
require 'connect_aircraftoperator.php';
$image = $db->query("SELECT * FROM company");
while ($row = $image->fetch_assoc()) {
echo '<img src="data:image/png;base64,' . base64_encode($row['companyImage']) . '" />';
}
?>
Below is my android code for now with the use of JSON.
try {
//setting up the default http client
HttpClient httpClient = new DefaultHttpClient();
//specify the url and the name of the php file that we are going to use
//as a parameter to the HttpPost method
HttpPost httpPost = new HttpPost("http://10.0.2.2//aircraftoperatorapp/leimage.php");
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
//getting the response
HttpResponse response = httpClient.execute(httpPost);
//setting up the entity
HttpEntity httpEntity = response.getEntity();
//setting up the content inside an input stream reader
//lets define the input stream reader
is = httpEntity.getContent();
}
catch (Exception e) {
System.out.println("Exception 1 Caught ");
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
//create a string builder object to hold data
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line+"\n");
}
//use the toString() method to get the data in the result
fullNameResult = sb.toString();
is.close();
//checks the data by printing the result in the logcat
System.out.println("---Here's my data---");
System.out.println(fullNameResult);
}
catch (Exception e){
System.out.println("Exception 2 Caught ");
}
//result now contains the data in the form of json
//let's inflate it in the form of the list
try {
//creates json array
JSONArray jArray = new JSONArray(fullNameResult);
for (int i = 0; i < jArray.length(); i++)
{
//create a json object to extract the data
JSONObject json_data = jArray.getJSONObject(i);
imageTemp = json_data.getString("companyImage"); //gets the value from the php
}
//this line should display the image from the mysql database into an image view
}
catch (Exception e){
//System.out.println("Exception 3 Caught ");
Log.e("lag_tag", "Error Parsing Data " + e.toString());
}
Thanks in advance for any help!
First use Base64 decode the string to byte array:
byte[] data = Base64.decode(imageTemp);
Bitmap b = BitmapFactory.decodeByteArray(data,0,data.length,null);
