Base64 Encodebytes - Out Of Memory Exception

I ma trying to upload a picture from android to remote server. Everything is working is fine except for large photos. I am getting 'memory out of exception' at Base64.encodeBytes()

Solution 1:

I had same problem before for large images...I have just scaled bitmap before converting it to Base64... you can use it as following...

bitmap=Bitmap.createScaledBitmap(bitmap, 100, 100, true);

ByteArrayOutputStreamstream=newByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream); //compress to which format you want.byte [] byte_arr = stream.toByteArray();
Stringimage_str= Base64.encodeBytes(byte_arr);

Solution 2:

Based on these statements:

1- I ma trying to upload a picture from android to remote server.

2- but its scaling the bimap rite ?? and i want to upload it in its original image.

I'm going to assume any answer will do as long as the solution helps you upload files to a server from android application and keeps the original image.

Solution - Remove the compression out of the tutorial below and it should send you on your way.

Avoid Base64.encodeBytes() for large image files.

Solution 3:

I found the solution regarding uploading exact original size of image to server:

publicstaticvoidupload(String pathToOurFile, String serverUrl){
    HttpURLConnectionconnection=null;
    DataOutputStreamoutputStream=null;
    DataInputStreaminputStream=null;

    StringurlServer= serverUrl;
    StringlineEnd="\r\n";
    StringtwoHyphens="--";
    Stringboundary="*****";

    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    intmaxBufferSize=1*1024*1024;

    try
    {
    FileInputStreamfileInputStream=newFileInputStream(newFile(pathToOurFile) );

    URLurl=newURL(urlServer);
    connection = (HttpURLConnection) url.openConnection();

    // Allow Inputs & Outputs
    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setUseCaches(false);

    // Enable POST method
    connection.setRequestMethod("POST");

    connection.setRequestProperty("Connection", "Keep-Alive");
    connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);

    outputStream = newDataOutputStream( connection.getOutputStream() );
    outputStream.writeBytes(twoHyphens + boundary + lineEnd);
    outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd);
    outputStream.writeBytes(lineEnd);

    bytesAvailable = fileInputStream.available();
    bufferSize = Math.min(bytesAvailable, maxBufferSize);
    buffer = newbyte[bufferSize];

    // Read file
    bytesRead = fileInputStream.read(buffer, 0, bufferSize);

    while (bytesRead > 0)
    {
    outputStream.write(buffer, 0, bufferSize);
    bytesAvailable = fileInputStream.available();
    bufferSize = Math.min(bytesAvailable, maxBufferSize);
    bytesRead = fileInputStream.read(buffer, 0, bufferSize);
    }

    outputStream.writeBytes(lineEnd);
    outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

    // Responses from the server (code and message)intserverResponseCode= connection.getResponseCode();
    StringserverResponseMessage= connection.getResponseMessage();

    fileInputStream.close();
    outputStream.flush();
    outputStream.close();
    }
    catch (Exception ex)
    {
    //Exception handling
    }
}

Solution 4:

you can try to change the quality parameter of compress like i have just given to 10 & it will work fine for large image also.

ByteArrayOutputStreamstream=newByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 10, stream); 
byte [] byte_arr = stream.toByteArray();
Stringimage_str= Base64.encodeBytes(byte_arr);
