This is my java file. I have already disabled the back button using
public void onBackPressed() {
// do nothing.
}
But when back button is pressed in the app, the entire screen becomes black. Please find screen shot . The app hangs and the only way it can be accessed by terminating it through task manager and then restarting it.
try this code for disable back button
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if(keyCode==KeyEvent.KEYCODE_BACK)
{
return true;
}
else
{
return super.onKeyDown(keyCode, event);
}
}
Capture Image from Camera and Display in Activity
I can't see a problem with your back button disabling. But there is another problem that may cause a part of this issue you are doing File IO in the UI Thread of your App.
Android has one UI Thread that does all the painting of your UI. If you block this thread through writing large files to the disk or reading bitmaps from the disk the phone UI will freeze and not react on user input until the heavy work is done.
I recommend to read this article on responsiveness to learn more about not blocking the UI Thread.
You can intercept the BackButton inside your own App, ONLY! As I see, you are starting some kind of CameraApp, that should pick a picture for you. You have NO control over the CameraActivity's BackButton. Your screen Has an ImageView, but you never set a Bitmap to it.
The disabling of the BackButton works, as you could NOT go out of your screen and have to "kill" it via a TaskManager. The BackButton has no functionality inside your Activity.

I know this was a common issue, but I have tried different suggestion, and still no solution.
My issue is that the bitmap is being displayed correctly, however SOMETIMES it saves as a black bitmap, while other times it saves correctly.
Can anyone see what I have done and tell me where I can be going wrong?
I have looked at most of the other StackOverflow questions.
The following is my code, which encodes the clip board text into a QR code and attempts to save the qr code generated.
Thank you!

Your code seems to be fine, the only thing that I saw is that you are getting you Bitmap from and external URL with Universal Image Loader instantly after calling displayImage. So is possible that for some delay in the network sometimes your ImageView still doesn't have the entire image and can make your bitmap saved as black.
Please try moving your all code bellow ImageLoader.getInstance().displayImage inside the onLoadingComplete like this:
ImageLoader.getInstance().displayImage(fullUrl, qrImg, defaultOptions, new SimpleImageLoadingListener()
{
#Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
ImageLoader.getInstance().displayImage(fullUrl, qrImg, defaultOptions,null);
qrImg.setDrawingCacheEnabled(true);
...
catch (Exception e) {
Toast.makeText(this, "Error occurred. Please try again later.",
Toast.LENGTH_SHORT).show();
}
}
});
Hope this help!!
Hi I'm working on an app in which I have to read images from whatsapp. I can read the first image as a bitmap with this line of code:
Bitmap btm = (Bitmap) sbn.getNotification().extras.get(Notification.EXTRA_PICTURE);
The problem is that if I receive more than one images I get null. How can I resolve this?
this is the NotificationListenerService:
package com.etaure.callany.testwhatsappimage;
import android.accounts.AccountManager;
import android.app.Notification;
import android.content.Intent;
import android.graphics.Bitmap;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.support.annotation.Nullable;
import android.support.v4.content.LocalBroadcastManager;
import android.text.TextUtils;
import android.util.Log;
import org.json.JSONArray;
/**
* Created by administrator on 03/11/2015.
*/
public class MyNotificationListner extends NotificationListenerService {
static int i = 0;
#Override
public void onNotificationPosted(StatusBarNotification sbn) {
if (sbn.getPackageName().equals("com.whatsapp")) {
Bitmap btm = (Bitmap) sbn.getNotification().extras.get(Notification.EXTRA_PICTURE);
}
}
#Override
public void onNotificationRemoved(StatusBarNotification sbn) {
Log.w("Test", "NotificationRemoved");
}
}
this is a code that parses for you whatsapp images and shows ( if you want ) on your logcat all base64 string! Enjoy
`
if (extras.containsKey(Notification.EXTRA_PICTURE)) {
bmp = (Bitmap) extras.get(Notification.EXTRA_PICTURE);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
byteArrayS = byteArrayOutputStream .toByteArray();
encoded = Base64.encodeToString(byteArrayS, Base64.DEFAULT);
final int LOGCAT_MAX_LENGTH = 3950;
if (BuildConfig.DEBUG) {
while (encoded.length() > LOGCAT_MAX_LENGTH) {
int substringIndex = encoded.lastIndexOf(",", LOGCAT_MAX_LENGTH);
if (substringIndex == -1)
substringIndex = LOGCAT_MAX_LENGTH;
Log.d("encode", encoded.substring(0, substringIndex));
encoded = encoded.substring(substringIndex).trim();
}
Log.d("encode", encoded);
}
}

I almost build my android application, but i have some troubles. My app use a ftp connection to upload photos on a server and display on screen this photos. With "upload part" i have no problems, but when i choose a photo and i want to display it on screen, I encounter some problems. Seems like my image is blurred or fragmented. I think that is from redimensioning, but in this way i tried many algorithms ...unsuccessful
Please tell me how can I display on screen an image from this ftp server, image displayed at good quality without "blurred or fragmented" part, thank you
This is my "show image" class...

Decoding and showing images seems to be OK. You could improve it by Loading Large Bitmaps Efficiently.
I'm not sure, but I think your problem should be this issue: https://code.google.com/p/android/issues/detail?id=6066
Try to create class:
public class FlushedInputStream extends FilterInputStream {
public FlushedInputStream(InputStream inputStream) {
super(inputStream);
}
#Override
public long skip(long n) throws IOException {
long totalBytesSkipped = 0L;
while (totalBytesSkipped < n) {
long bytesSkipped = in.skip(n - totalBytesSkipped);
if (bytesSkipped == 0L) {
int by_te = read();
if (by_te < 0) {
break; // we reached EOF
} else {
bytesSkipped = 1; // we read one byte
}
}
totalBytesSkipped += bytesSkipped;
}
return totalBytesSkipped;
}
}
and use:
bm = BitmapFactory.decodeStream(new FlushedInputStream(entity.getContent()));

This code will use your phone's default camera, if you need to use their client, you will need to start their CaptureActivity, Your layout should include a TextView to show results, ImageView to show the image you captured, and Button to start the camera. . This is based off of 2.1zxing.
You can use:
zbar (SDK has a good example).

Hey download a sample of Biggu Barcode Scanner from this link, extract the Demo Project and import it to eclipse. The zip file has Demo Example, which you can use and integrate in your app as per your requirement

I have file explorer which is working fine, I can see images and music on sdcard and i am able to delete then also. But after deletion they should go to Recycle folder (as stated in C.java ). I have created Recycle Folder (/mnt/sdcard/Recycle) manually using file explorer in eclipse.
But i don't see files in recycle folder.
Is there any problem with the Code ?
Any kind of Help will be appreciated.
Thanks !!
Have you Debug and make sure the copyfile has been executed?
And this is My CopyFile function, and they are quite the same:
public static boolean copyFile(String from, String to) {
try {
int bytesum = 0;
int byteread = 0;
File oldfile = new File(from);
if (oldfile.exists()) {
InputStream inStream = new FileInputStream(from);
FileOutputStream fs = new FileOutputStream(to);
byte[] buffer = new byte[1444];
while ((byteread = inStream.read(buffer)) != -1) {
bytesum += byteread;
fs.write(buffer, 0, byteread);
}
inStream.close();
fs.close();
}
return true;
} catch (Exception e) {
return false;
}
}
Try following Code, it will Work.
public void Save_To_Phone(Bitmap bitmap){
try {
FileOutputStream os = new FileOutputStream(YourSDCardPath);
bitmap.compress(CompressFormat.JPEG, 80, os);
os.close();
} catch (Exception e) {
Log.w("ExternalStorage", "Error writing file", e);
}
}
