I have a situation with three image buttons:
Take a photo by the camera
Delete the photo
Show a cropped2fit version of the image taken
I'm using the camera of the phone.
My problem is that SOMETIMES, apparently without no explanation, when I set the photo with setImageBitmap, it goes on the wrong imageButton (seems to be always the delete button, but I'm not really sure). Rebooting the device seems to solve the problem.
The code is as simple as it should be: I use findViewById casting the object into an ImageButton and setting the image with setImageBitmap.
ImageView iv = ((ImageView) findViewById(R.id.imgFotoPrima));
iv.setImageBitmap(fn.setupImage(data, PrimaOutputFileUri));
iv.setScaleType(ScaleType.CENTER_CROP);
public static Bitmap setupImage(Intent data, Uri outputFileUri) {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2; // SAMPLE_SIZE = 2
Bitmap tempBitmap = null;
Bitmap bm = null;
try {
tempBitmap = (Bitmap) data.getExtras().get("data");
bm = tempBitmap;
Log.v("ManageImage-hero", "the data.getData seems to be valid");
FileOutputStream out = new FileOutputStream(outputFileUri.getPath());
tempBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
}
catch (NullPointerException ex) {
Log.v("ManageImage-other", "another phone type");
bm = otherImageProcessing(options, outputFileUri);
}
catch (Exception e) {
Log.e("ManageImage-setupImage", "problem setting up the image", e);
}
return bm;
}
The elements in the xml have different id.
I've tried the application on a Lenovo (7') and a Galaxy Tab 7 II.
It seems to happen only on the Galaxy Tab.
Could it be a problem on the tablet?? Anyone in my situation?

I have to play a video in one of my screens of Android and I am using Video View intent for the same. The video gets played but there is no thumbnail appearing on the launch of the screen.
My code is like this
#OnClick(R.id.icon_play)
protected void playVideo(){
String videoUrl="https://someUrl/Video/v07.mp4";
if(!videoUrl.isEmpty()) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(videoUrl));
intent.setDataAndType(Uri.parse(videoUrl), "video/mp4");
startActivity(intent);
}
}
By thumbnail, I mean that when the screen is launched each video should have an image of its own. (something like YouTube)
I tried seekTo() for attaching the thumbnail, but it didn't work.
Please Help. Thanks.
I solve the problem using MediaMetaDataRetriever.
The code goes like this-
public static Bitmap retriveVideoFrameFromVideo(String videoPath)
throws Throwable
{
Bitmap bitmap = null;
MediaMetadataRetriever mediaMetadataRetriever = null;
try
{
mediaMetadataRetriever = new MediaMetadataRetriever();
if (Build.VERSION.SDK_INT >= 14)
mediaMetadataRetriever.setDataSource(videoPath, new HashMap<String, String>());
else
mediaMetadataRetriever.setDataSource(videoPath);
// mediaMetadataRetriever.setDataSource(videoPath);
bitmap = mediaMetadataRetriever.getFrameAtTime(-1,MediaMetadataRetriever.OPTION_CLOSEST);
}
catch (Exception e)
{
e.printStackTrace();
throw new Throwable(
"Exception in retriveVideoFrameFromVideo(String videoPath)"
+ e.getMessage());
}
finally
{
if (mediaMetadataRetriever != null)
{
mediaMetadataRetriever.release();
}
}
return bitmap;
}
Note that : Because my video link was in the form of server URL, that's why createThumnailUtils was returning a null when video Url was passed through it.
The below code works fine when the video is coming from local storage.
Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail("URL", MediaStore.Images.Thumbnails.MINI_KIND);
BitmapDrawable bitmapD = new BitmapDrawable(thumbnail);
VideoView.setBackground(Drawable bitmapD);
Hope this helps someone!!
Just looked at another example. Not 100% sure if it's going to work but worth a try.
Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail("URL", MediaStore.Images.Thumbnails.MINI_KIND);
BitmapDrawable bitmapD = new BitmapDrawable(thumbnail);
VideoView.setBackground(Drawable bitmapD);
Please note, I have written this over phone so there might be spelling errors.
Let me know if this works or if you find another alternative
this may be used i am using this method for thumbnail image of video on my list view of video player..
Cursor cursor = mContext.getContentResolver().query(
MediaStore.Video.Media.EXTERNAL_CONTENT_URI, proj,
MediaStore.Video.Media.DISPLAY_NAME + "=?",
new String[]{localItem._display_name}, null);
cursor.moveToFirst();
long ids = cursor.getLong(cursor
.getColumnIndex(MediaStore.Video.Media._ID));
ContentResolver crThumb = mContext.getContentResolver();
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(
crThumb, ids, MediaStore.Video.Thumbnails.MICRO_KIND,
options);
itemHolder.thumbImage.setImageBitmap(curThumb);
curThumb = null;
cursor.close();
try this way it may be helpful
above ans is now deprecated.
new updated answer with fast one solution
we just have to give the video data path
Bitmap bmThumbnail;
bmThumbnail = ThumbnailUtils.createVideoThumbnail(arraylist.get(i)._data, MediaStore.Video.Thumbnails.MICRO_KIND);
itemHolder.thumbImage.setImageBitmap(bmThumbnail);
where arraylist.get(i)._data => path of video.
and best way is to use Glide or any other image lodging async library for smooth scrolling of listview.
I'm using following code from here. I want to compress image.
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
Bitmap bmp = BitmapFactory.decodeFile(filePath, options);
int actualHeight = options.outHeight;
int actualWidth = options.outWidth;
After choose image from Camera, Gallery and Photos, i'm getting different type of paths in different devices based on OS type and device model. like:
1) /storage/emulated/0/Android/data/...
2) /raw//storage/emulated/0/mb/1511172993547.jpg
3) /2/1/content://media/external/images/media/11647/ORIGINAL/NONE/486073582
If path is like 1st url, this code is working fine. But if i get other types of images, then BitmapFactory.decodeFile() is giving null.
Is there any way to compress image in all types of devices and OS versions.
UPDATE :
To Open Picker :
Intent pickIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
pickIntent.setType("image/*");
startActivityForResult(pickIntent, 1001);
After choosing image :
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Uri imgUri = Uri.fromFile(new File(data.getData().getPath()));
Bitmap cmpBitmap = ImageUtils.compressUriQuality(OpenWallWeb.this, imgUri);
dlgImageToPost.setImageBitmap(cmpBitmap);
...
}
For compression :
public static Bitmap compressUriQuality(Context mContext, Uri selectedImage) {
InputStream imageStream = null;
Bitmap bmp = null;
try {
imageStream = mContext.getContentResolver().openInputStream(
selectedImage);
bmp = BitmapFactory.decodeStream(imageStream);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 50, stream);
if (imageStream != null)
imageStream.close();
stream.close();
stream = null;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return bmp;
}
Tv 2) /raw//storage/emulated/0/mb/1511172993547.jpg
That is not a path you would get if the user selected pictures from Gallery or Photos. And certainly it is no file system path you could use for .decodeFile(). How did you obtain it?
3) /2/1/content://media/external/images/media/11647/ORIGINAL/NONE/486073582
That is no valid content scheme path. How did you obtain it? And certainly cannot be used for .decodeFile().
i'm getting different type of paths
You will never get such paths if you 'act normal'. So what is it what you are doing? Elementary uri handling wrong?
using following code from here.
That is pretty dirty example code for a big part as you have perceived now.
any way to compress image in all types of devices and OS versions.
Of course. Just use the obtained selected uri directly. Open an InputStream for it and use .decodeStream() instead.
My god.. you are not using the uri directly.
Bitmap cmpBitmap = ImageUtils.compressUriQuality(OpenWallWeb.this, imgUri);
Change to
Bitmap cmpBitmap = ImageUtils.compressUriQuality(OpenWallWeb.this, data.getData());
I had same issue, please add storage permission to your app.

I am using edmodo/cropper library to crop the image after the user has taken the image from camera.
Link: https://github.com/edmodo/cropper/wiki
I got this issue on device GT-N7000 and some other android phones.
java.lang.OutOfMemoryError
1 at android.graphics.Bitmap.nativeCreate(Native Method)
2 at android.graphics.Bitmap.createBitmap(Bitmap.java:669)
3 at android.graphics.Bitmap.createBitmap(Bitmap.java:604)
4 at android.graphics.Bitmap.createBitmap(Bitmap.java:530)
5 at com.edmodo.cropper.CropImageView.getCroppedImage(CropImageView.java:357)
Does anyone know how to solve this issue. Please help me ,the device keep getting crashes.
I solved it by subsampling the captured image before storing it in cropView using BitmapFactory.Options.
Here is the code:
// setting path to the clicked image and cropped image
path_click = "sdcard/Pictures/Candice/Clicked.jpg";
path_crop = "sdcard/Pictures/Candice/Cropped.jpg";
final BitmapFactory.Options options = new BitmapFactory.Options();
//If set to a value > 1,requests the decoder to subsample the
//original image, returning a smaller image to save memory.
options.inSampleSize = 2;
clickedImage = BitmapFactory.decodeFile(path_click, options);
cropImageView.setImageBitmap(clickedImage);
// Sets initial aspect ratio to 10/10, for demonstration purposes
cropImageView.setAspectRatio(DEFAULT_ASPECT_RATIO_VALUES,
DEFAULT_ASPECT_RATIO_VALUES);
cropButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Here we save the cropped image and then call the next
// activity
// To retrieve the image contained within the Cropper window,
// use the provided method, getCroppedImage() to retrieve a
// Bitmap of the cropped image.
croppedImageBitmap = cropImageView.getCroppedImage();
/** Save cropped image to SD card using output streams **/
// An output stream that writes bytes to a file.
// If it does not exist, a new file will be created.
FileOutputStream out = null;
try {
out = new FileOutputStream(path_crop);
// Writing a compressed version of bitmap to outputstream.
croppedImageBitmap.compress(Bitmap.CompressFormat.JPEG, 90,
out);
// Just after compression,add
croppedImageBitmap.recycle();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
startActivity(chooseIntent);
}
});
I don't know how big is your image, but have you tried adding android:largeHeap="true" to your <application> tag in the AndroidManifest.xml?
So I have the following code in an AsyncTask. The AsyncTask takes in a url to an image file, downloads it into a Bitmap, saves the Bitmap off to disk somewhere, and then displays the Bitmap in an existing ImageView.
Here's the implementation of the doInBackground() call for my AsyncTask:
protected Bitmap doInBackground(String... urls) {
try {
URL image_url = new URL(urls[0]);
String image_url_prefix_regex = "http://www\\.somewebsite\\.com";
if (externalStorageIsAvailable()) {
String file_path = getExternalFilesDir(null).getPath() + image_url.toString().replaceAll(image_url_prefix_regex, "");
File target_file = new File(file_path);
if (!target_file.getParentFile().exists()) {
target_file.getParentFile().mkdirs();
}
BitmapFactory.Options bitmap_options = new BitmapFactory.Options();
bitmap_options.inScaled = false;
bitmap_options.inDither = false;
bitmap_options.inPreferredConfig = Bitmap.Config.ARGB_8888;
bitmap_options.inPreferQualityOverSpeed = true;
bitmap_options.inSampleSize = 1;
Bitmap image = BitmapFactory.decodeStream(image_url.openStream(), null, bitmap_options);
image.compress(CompressFormat.JPEG, 100, new FileOutputStream(target_file));
return image;
}
}
catch (MalformedURLException e) {
Log.v(DEBUG_TAG, "Error: Caught MalformedURLException");
}
catch (IOException e) {
Log.v(DEBUG_TAG, "Error: Caught IOException");
}
return null;
}
Then later in the onPostExecute() call I have this:
protected void onPostExecute(Bitmap image) {
ImageView mImageView = (ImageView) findViewById(R.id.main_image);
mImageView.setImageBitmap(image);
}
Yet when the code downloads and displays the image, the image is reduced in size and quality. How do I make it so that the resulting image is full quality? Those BitmapFactory.Options settings are the things I've tried thus far, but they did not seem to work.
Note that I'm not asking about the image that gets saved to external storage. I think that one will likely be of lower quality due to getting compressed again, but that shouldn't affect the image I'm sending to my ImageView, which is what I'm asking about. Of course, if there's anything wrong with these assumptions please point them out.
Why you are using Bitmap factory options while decoding bitmap Stream ?
Just use the
Bitmap image = BitmapFactory.decodeStream(image_url.openStream());
instead of
Bitmap image = BitmapFactory.decodeStream(image_url.openStream(), null, bitmap_options);
I am trying to use an image from the sd card and set it as the background for a relativelayout. I have tried other solutions that i have found here and elsewhere but they havent seemed to work for me. here is my code. I have commented out other ways that i have tried and didnt work. the only thing that worked for me was using setBackgroudnResource and using a resource from the app, but this was just to test to make sure mRoot was set up correctly. when I have tried all the other ways, it just doesn't set anything. Anyone know what I am doing wrong, or if there is a better way to do this?
//one way i tired...
//String extDir = Environment.getExternalStorageDirectory().toString();
//Drawable d = Drawable.createFromPath(extDir + "/pic.png");
//mRoot.setBackgroundDrawable(d);
//another way tried..
//Drawable d = Drawable.createFromPath("/sdcard/pic.png");
//mRoot.setBackgroundDrawable(d);
//last way i tried...
mRoot.setBackgroundDrawable(Drawable.createFromPath(new File(Environment.getExternalStorageDirectory(), "pic.png").getAbsolutePath()));
//worked, only to verify mRoot was setup correctly and it could be changed
//mRoot.setBackgroundResource(R.drawable.bkg);
You do not load a drawable from SD card but a bitmap. Here is a method to load it with the reduced sampling (quality) so the program will not complain if the image is too large. Then I guess you need to process this bitmap i.e. crop it and resize for the background.
// Read bitmap from Uri
public Bitmap readBitmap(Uri selectedImage) {
Bitmap bm = null;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2; //reduce quality
AssetFileDescriptor fileDescriptor =null;
try {
fileDescriptor = this.getContentResolver().openAssetFileDescriptor(selectedImage,"r");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
finally{
try {
bm = BitmapFactory.decodeFileDescriptor(fileDescriptor.getFileDescriptor(), null, options);
fileDescriptor.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return bm;
}
The Uri here can be supplied from a gallery picker activity.
The image then can be saved into application resources and loaded into an imageView
private void saveBackground(Bitmap Background) {
String strBackgroundFilename = "background_custom.jpg";
try {
Background.compress(CompressFormat.JPEG, 80, openFileOutput(strBackgroundFilename, MODE_PRIVATE));
} catch (Exception e) {
Log.e(DEBUG_TAG, "Background compression and save failed.", e);
}
Uri imageUriToSaveCameraImageTo = Uri.fromFile(new File(BackgroundSettings.this.getFilesDir(), strBackgroundFilename));
// Load this image
Bitmap bitmapImage = BitmapFactory.decodeFile(imageUriToSaveCameraImageTo.getPath());
Drawable bgrImage = new BitmapDrawable(bitmapImage);
//show it in a view
ImageView backgroundView = (ImageView) findViewById(R.id.BackgroundImageView);
backgroundView.setImageURI(null);
backgroundView.setImageDrawable(bgrImage);
}
File file = new File( url.getAbsolutePath(), imageUrl);
if (file.exists()) {
mDrawable = Drawable.createFromPath(file.getAbsolutePath());
}
I suggest checking that the drawable is being loaded correctly. Some things to try:
Try using a different image on the sd card
Put pic.png in R.drawable and make sure mRoot.setBackgroundResource() does what you expect
After loading the drawable, check d.getBounds() to make sure it is what you expect
