So i have 2 Activities, the first one is to launch camera before the second Activity start. After taking the camera, the ImageView on second Activities will changed by the photo ive taken. And if i click the ImageView, it will intent the camera and replacing the image from camera. However, i cant replace the image at ImageView and the resultCode always 0 everytime after taking picture.
here is first Activity

storage permission already checked on manifest
i used a combination of answers to make it work so i ended up with this code:
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Date dat = Calendar.getInstance().getTime();
SimpleDateFormat simpleDate = new SimpleDateFormat("yyyy-mm-dd-hh:mm:ss");
String nameFoto = simpleDate.format(dat) + ".png";
String filename = Environment.getExternalStorageDirectory().getAbsolutePath() + "/"+ File.separator +nameFoto;
File ff = new File(filename);
try {
ff.createNewFile();
//imageUri = Uri.fromFile(ff);
imageUri = FileProvider.getUriForFile(IngresarFactura.this, BuildConfig.APPLICATION_ID + ".provider",ff);
//imageUri = new Uri(filename).
if (imageUri.getPath() == null){
mensaje.setText(filename+ " Error path es nulo.");
}
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageUri);
//COMPATIBILITY
if (Build.VERSION.SDK_INT>= Build.VERSION_CODES.LOLLIPOP) {
cameraIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
} else {
List<ResolveInfo> resInfoList = IngresarFactura.this.getPackageManager().queryIntentActivities(cameraIntent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
String packageName = resolveInfo.activityInfo.packageName;
IngresarFactura.this.grantUriPermission(packageName, imageUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
}
//COMPATIBILITY
activityResultLaunch.launch(cameraIntent);
}
you also have to do this as answered here:

I just got started in Android Programming and I am creating an android application in which the user is allowed to key in information, take a picture with ImageView implemented and SAVE the information. I've gotten up to the point where I am able to display the image taken into ImageView. However, I am unable to save the image taken into my phone's internal storage. Which means, whenever I try to save the information, including the ImageView (image from camera), only the image disappears. I've followed this guide on http://www.androidhive.info/2013/09/android-working-with-camera-api/ but it does not work as my phone has no SD card storage.
I've read a bunch of questions on here but they do not fix the problem.
So if anyone could give me a detailed procedure on how to edit this code in such a way that I can save/read the image into/from my INTERNAL storage that would be great! Thank you.

getOutputMediaFile() is returning a directory, not a file. You need to specify a path to a (not-yet-existing) file where you want the image to be written.
This is illustrated in this activity from this sample application:
package com.commonsware.android.camcon;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;

private static final int CONTENT_REQUEST=1337;
private File output=null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent i=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File dir=
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
output=new File(dir, "CameraContentDemo.jpeg");
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(output));
startActivityForResult(i, CONTENT_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == CONTENT_REQUEST) {
if (resultCode == RESULT_OK) {
Intent i=new Intent(Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(output), "image/jpeg");
startActivity(i);
finish();
}
}
}
}
I have implemented many imageviews with a camera icon so that when the user touches on the icon it starts the camera and when the picture is taken it returns to the original activity where the camera intent was called and display the captured image in the imageviews.
The problem is this works ok with in my Jellybean 4.2.2. But in some phones having kitkat and Jellybean 4.2.1, when the camera is loaded and the picture is taken it gives an option to save or discard the captured image (in my phone no option is given to save) and when i click save the app crashes. Sometimes even in my phone it returns to previous activity but doesn't show the captured images.
Please help me if you can.I am posting the essential code below

I seem to be having trouble creating a Bitmap from fileUri.
I would like to be able to set this Bitmap to an Imageview for previewing the image, and later adding elements to the image.
Any ideas why the image does not get set properly?

Presumably your process was terminated while you were in the background. Do not rely upon static data members for anything more than a cache.
what did you do to BugTrackerApp? Have you checked it?
Why do you need the two lines?
BugTrackerApp.app.file =file ;
file = BugTrackerApp.app.file ;
You created a file to store captured image, and decoded it in onActivityResult. so this line
file = new File(Environment.getExternalStorageDirectory()
+ File.separator + "test.png");
is enough.
