Dear Sir/madam,
When i'm using connectionRequest to upload file to OneDrive, there is
always out of memory error when the size of file is just a little large,
say, over 60MB. Herewith attach a sample code i wrote.
/**
* Your application code goes here
*/
package userclasses;
import com.codename1.io.BufferedOutputStream;
import com.codename1.system.NativeLookup;
import com.codename1.util.Base64;
import generated.StateMachineBase;
import com.codename1.ui.*;
import com.codename1.ui.events.*;
import com.codename1.ui.util.Resources;
import com.codename1.io.*;
import java.io.*;
import java.util.ArrayList;
import java.util.Date;
import java.util.Random;
public class StateMachine extends StateMachineBase {
public StateMachine(String resFile) {
super(resFile);
// do not modify, write code in initVars and initialize class
members there,
// the constructor might be invoked too late due to race conditions
that might occur
}
protected void initVars(Resources res) {
}
@Override
protected void onMain_ButtonAction(Component c, ActionEvent event) {
Display.getInstance().invokeAndBlock(new Runnable() {
BackupOneDrive task = new BackupOneDrive();
@Override
public void run() {
// new Thread(task).start();
task.run();
}
});
}
class BackupOneDrive extends Thread {
public BackupOneDrive() {
}
public void run() {
try {
ConnectionRequest req = new ConnectionRequest() {
@Override
protected void buildRequestBody(OutputStream os) throws
IOException {
System.out.println("Request Body");
byte[] b = new byte[157286400];
new Random().nextBytes(b);
InputStream inputStream = new
ByteArrayInputStream(b);
synchronized (inputStream) {
BufferedOutputStream bos = new
BufferedOutputStream(os);
try {
byte[] buffer = new byte[4096];
int length = 0;
while ((length = inputStream.read(buffer))
!= -1) {
System.out.println("length: " +
buffer.toString());
bos.write(buffer, 0, length);
bos.flush();
}
inputStream.close();
} catch (Throwable e) {
e.printStackTrace();
} finally {
bos.close();
}
}
}
};
req.setDuplicateSupported(true);
req.setSilentRetryCount(10);
req.setTimeout(3000);
NetworkManager.getInstance().setTimeout(3000);
req.setReadResponseForErrors(false);
req.setChunkedStreamingMode(4096);
req.setPriority(ConnectionRequest.PRIORITY_CRITICAL);
req.setPost(true);
req.addResponseListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent evt) {
NetworkEvent e = (NetworkEvent) evt;
if (e.getError() != null) {
e.consume();
System.out.println("error: " +
e.getError().getMessage());
return;
}
}
});
req.setUrl("https://apis.live.net/v5.0/{folder}/files/test.mp4?access_token={AccessToken}&downsize_photo_uploads=false";);
req.setHttpMethod("PUT");
req.setContentType("");
NetworkManager.getInstance().addToQueueAndWait(req);
System.out.println("finish");
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
}
In that case, I just use a random byte about 150MB and the out of memory
came out at about 60MB.
Moreover, the error happens in both simulator and real mobile.
Please advice and suggest us a solution.
Thanks and Regards,
Roanld
