Ok Time to pay back.
So u have your permissions on Mainfest
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-feature android:name="android.hardware.camera" android:required="true" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
and u also have your provider meta-data
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths"></meta-data>
</provider>
One missed detail is (android:authorities applicationId) u need to add your own app package name.
So u have xml file under res folder as we mentioned on manifest and under it u have created file_paths with ;
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-files-path
name="my_images"
path="Pictures" />
</paths>
we are done with copy paste part 1. Now on our activity above onCreate(savedInstanceState: Bundle?) define these beauties
val REQUEST_IMAGE_CAPTURE = 1
lateinit var currentPhotoPath: String
var cameraIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
U might like to have a look at original resource but missing details as usual Android Developers : link
An other missing detail is packageName + ".fileprovider", be carefull u need to give your own package name if u allredy have method.
// org android developers
private fun dispatchTakePictureIntent() {
Intent(MediaStore.ACTION_IMAGE_CAPTURE).also { takePictureIntent ->
// Ensure that there's a camera activity to handle the intent
takePictureIntent.resolveActivity(packageManager)?.also {
// Create the File where the photo should go
val photoFile: File? = try {
createImageFile()
} catch (ex: IOException) {
// Error occurred while creating the File
ex.message
null
}
// Continue only if the File was successfully created
photoFile?.also {
val photoURI: Uri = FileProvider.getUriForFile(
this,
packageName + ".fileprovider",
it
)
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI)
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE)
}
}
}
}
createImageFile function
// org android developers
@Throws(IOException::class)
private fun createImageFile(): File {
// Create an image file name
val timeStamp: String = SimpleDateFormat("yyyyMMdd_HHmmss").format(Date())
val storageDir: File = this!!.getExternalFilesDir(Environment.DIRECTORY_PICTURES)!!
return File.createTempFile(
"JPEG_${timeStamp}_", /* prefix */
".jpg", /* suffix */
storageDir /* directory */
).apply {
// Save a file: path for use with ACTION_VIEW intents
currentPhotoPath = absolutePath
}
}
Testing.
call your dispatchTakePictureIntent() method with onClick event, make sure permissions are permitted
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && requestCode == REQUEST_IMAGE_CAPTURE) {
var mBitmap_org = MediaStore.Images.Media.getBitmap(
this.getContentResolver(),
//Uri.parse(currentPhotoPath)
Uri.fromFile(File(currentPhotoPath))
);
//mImg_display?.setImageBitmap(mBitmap_org)
}
}
Don't check data we will get it through imagePath. If u are checking Uri.parse(currentPhotoPath) make sure it's Uri.fromFile(File(currentPhotoPath))
Now u have your bitmap, time to spend other hours/days how to resize decode, save.
There is also a method to save tokken image, maybe you could help me to see where should I put it, if I need tokken image to be save on gallery
// org android developers
private fun galleryAddPic() {
Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE).also { mediaScanIntent ->
val f = File(currentPhotoPath)
mediaScanIntent.data = Uri.fromFile(f)
sendBroadcast(mediaScanIntent)
}
}
