CameraX - I/zygote: Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>

I am developing a simple app based on the CameraX Jetpack support library through the provided getting started guide and a GitHub repo. Getting the error
I/zygote: Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>:
java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;
when I set the layout of the sample activity (CameraActivity). Tested the sample code on both the virtual and real devices on API level 26. The version of the CameraX library is 1.0.0-alpha03 which is the latest available version.
Here is the code of my layout:
<TextureView
android:id="#+id/textureView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ImageButton
android:id="#+id/btnCapture"
android:layout_width="72dp"
android:layout_height="72dp"
android:scaleType="fitCenter"
android:layout_margin="24dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"

float cX = w / 2f; //calc centre of the viewfinder
float cY = h / 2f;

int rotation = (int) textureView.getRotation(); //cast to int bc switches don't like floats
switch (rotation) { //correct output to account for display rotation
case Surface.ROTATION_0:

}

Solved the issue for me.

Wat to do if i want to set image in imageview of my adapter wid id ivReceiverSign?

Create interface
public interface ImageUrl{
void getImageUrl(String imageUrl)
}
implement this interface in adapter and send the url through another class using imageUrl.getImageUrl(imageUrl).
or Use EventBus library.
Reference to Eventbus : Green robot Event bus

My imageView doesn`t work

I am working in android studio and I'm triyng to import a photo from a directory from my phone and put it on a ImageView.
In my first activity, I tried to save the photo using the camera and I tried to save the URI from the photo. That's working.
IIn another activity, I tried to import that URI but my ImageView doesn't change. The compiler saw location from the photo, so I think is working, but the imageview can't import the photo...
Could you help me?

Android code to record a video using remote IP camera which is accessed by using a url

Here are some links which tell about video recording:
How can I capture a video recording on Android?
https://github.com/churnlabs/android-ffmpeg-sample
and there are also many links which tell about video recording but got no any clue how to use the remote IP camera to record video.
By using different samples on stackoverflow I become able to take picture and save on sdcard but couldn't record video.
If any one has any idea or code along with required files I will be thankful.
For example the url I am using where the IP camera is available is given below:

Show Image View from file path?

I need to show an image by using the file name only, not from the resource id.
ImageView imgView = new ImageView(this);
imgView.setBackgroundResource(R.drawable.img1);
I have the image img1 in the drawable folder. I wish to show that image from the file.
How can I do this?

Labeeb is right about why you need to set image using path if your resources are already laying inside the resource folder ,
This kind of path is needed only when your images are stored in SD-Card .
And try the below code to set Bitmap images from a file stored inside a SD-Card .
File imgFile = new File("/sdcard/Images/test_image.jpg");
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);
myImage.setImageBitmap(myBitmap);
}
And include this permission in the manifest file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I think you can use this
Bitmap bmImg = BitmapFactory.decodeFile("path of your img1");
imageView.setImageBitmap(bmImg);

You can also use:
File imgFile = new File(“filepath”);
if(imgFile.exists())
{
ImageView myImage = new ImageView(this);
myImage.setImageURI(Uri.fromFile(imgFile));
}
This does the bitmap decoding implicit for you.

All the answers are outdated. It is best to use picasso for such purposes. It has a lot of features including background image processing.
Did I mention it is super easy to use:
Picasso.with(context).load(new File(...)).into(imageView);

String path = Environment.getExternalStorageDirectory()+ "/Images/test.jpg";
File imgFile = new File(path);
if(imgFile.exists())
{
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView imageView=(ImageView)findViewById(R.id.imageView);
imageView.setImageBitmap(myBitmap);
}

From the official site: http://developer.android.com/training/displaying-bitmaps/load-bitmap.html
ImageView image = (ImageView) findViewById(R.id.imagePreview);
try {
image.setImageBitmap(decodeSampledBitmap(picFilename));
} catch (Exception e) {
e.printStackTrace();
}
Here the methods:
private int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
private Bitmap decodeSampledBitmap(String pathName,
int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(pathName, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(pathName, options);
}
//I added this to have a good approximation of the screen size:
private Bitmap decodeSampledBitmap(String pathName) {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
return decodeSampledBitmap(pathName, width, height);
}

You can use:
ImageView imgView = new ImageView(this);
InputStream is = getClass().getResourceAsStream("/drawable/" + fileName);
imgView.setImageDrawable(Drawable.createFromStream(is, ""));

You may use this to access a specific folder and get particular image
public void Retrieve(String path, String Name)
{
File imageFile = new File(path+Name);
if(imageFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(path+Name);
myImage = (ImageView) findViewById(R.id.savedImage);
myImage.setImageBitmap(myBitmap);
Toast.makeText(SaveImage.this, myBitmap.toString(), Toast.LENGTH_LONG).show();
}
}
And then you can call it by
Retrieve(Environment.getExternalStorageDirectory().toString()+"/Aqeel/Images/","Image2.PNG");
Toast.makeText(SaveImage.this, "Saved", Toast.LENGTH_LONG).show();

public static Bitmap decodeFile(String path) {
Bitmap b = null;
File f = new File(path);
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
FileInputStream fis = null;
try {
fis = new FileInputStream(f);
BitmapFactory.decodeStream(fis, null, o);
fis.close();
int IMAGE_MAX_SIZE = 1024; // maximum dimension limit
int scale = 1;
if (o.outHeight > IMAGE_MAX_SIZE || o.outWidth > IMAGE_MAX_SIZE) {
scale = (int) Math.pow(2, (int) Math.round(Math.log(IMAGE_MAX_SIZE / (double) Math.max(o.outHeight, o.outWidth)) / Math.log(0.5)));
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
fis = new FileInputStream(f);
b = BitmapFactory.decodeStream(fis, null, o2);
fis.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return b;
}
public static Bitmap showBitmapFromFile(String file_path)
{
try {
File imgFile = new File(file_path);
if(imgFile.exists()){
Bitmap pic_Bitmap = decodeFile(file_path);
return pic_Bitmap;
}
} catch (Exception e) {
MyLog.e("Exception showBitmapFromFile");
return null;
}
return null;
}
if you are using image loading in List view then use Aquery concept .
https://github.com/AshishPsaini/AqueryExample
AQuery aq= new AQuery((Activity) activity, convertView);
//load image from file, down sample to target width of 250 pixels .gi
File file=new File("//pic/path/here/aaaa.jpg");
if(aq!=null)
aq.id(holder.pic_imageview).image(file, 250);

onLoadImage Full load
private void onLoadImage(final String imagePath) {
ImageSize targetSize = new ImageSize(imageView.getWidth(), imageView.getHeight()); // result Bitmap will be fit to this size
//ImageLoader imageLoader = ImageLoader.getInstance(); // Get singleto
com.nostra13.universalimageloader.core.ImageLoader imageLoader = com.nostra13.universalimageloader.core.ImageLoader.getInstance();
imageLoader.init(ImageLoaderConfiguration.createDefault(getContext()));
imageLoader.loadImage(imagePath, targetSize, new SimpleImageLoadingListener() {
#Override
public void onLoadingStarted(final String imageUri, View view) {
super.onLoadingStarted(imageUri, view);
progress2.setVisibility(View.VISIBLE);
new Handler().post(new Runnable() {

// Picasso.with(getContext()).load(imagePath).into(imageView);
// Picasso.with(getContext()).load(imagePath) .memoryPolicy(MemoryPolicy.NO_CACHE, MemoryPolicy.NO_STORE).into(imageView);
Glide.with(getContext())
.load(imagePath)
.asBitmap()
.into(imageView);
}
});
}
#Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
if (view == null) {
progress2.setVisibility(View.INVISIBLE);
}
// else {
Log.e("onLoadImage", "onLoadingComplete");
// progress2.setVisibility(View.INVISIBLE);

Most of the answers are working but no one mentioned that the high resolution image will slow down the app , In my case i used images RecyclerView which was taking 0.9 GB of device memory In Just 30 Images.
I/Choreographer: Skipped 73 frames! The application may be doing too
much work on its main thread.
The solution is Sipmle you can degrade the quality like here : Reduce resolution of Bitmap
But I use Simple way , Glide handles the rest of work
fanContext?.let {
Glide.with(it)
.load(Uri.fromFile(File(item.filePath)))
.into(viewHolder.imagePreview)
}

You can easily do this using bitmap. You can find the code below :
ImageView imageView=findViewById(R.id.imageView);
Bitmap bitMapImage= BitmapFactory.decodeFile("write path of your image");
imageView.setImageBitmap(bitMapImage);

mageView.setImageResource(R.id.img);
