Print logo on top of recipe android

Hello guys i have the problem that i want to include an image in my project and when the user click the print button the image will be printet followed by other information but i dont get it to pass the image path to the PrintTool
PrintTool.printPhotoWithPath(imagePath, this);
and the first line in printtool are this
public static void printPhotoWithPath(String filePath, Context context) {
// Get the picture based on the path
File mfile = new File(filePath/*path*/);
if (mfile.exists()) {
Bitmap bmp = BitmapFactory.decodeFile(filePath/*path*/);
byte[] command = decodeBitmap(bmp);
printPhoto(command, context);
}else{
Log.e("PrintTools_58mm", "the file isn't exists");
}
}
So my problem is, how can i get the path from my image in drawable folder to the code?

Please remove this line
File mfile = new File(filePath/*path*/);
Provided the image is currently in your drawable directory, you can get it like this:
if (mfile.exists()) {
Bitmap bmp = BitmapFactory.decodeFile(getResources(), R.drawable.<yourDrawableName>);
byte[] command = decodeBitmap(bmp);
printPhoto(command, context);
}else{
Log.e("PrintTools_58mm", "the file isn't exists");
}
NB Replace with the name of your Drawable.
If you require the path of the Bitmap, by default it is
String imageUri = "drawable://" + R.drawable.image;
Refer to this.

i hope this helps you
File file = new File(String.valueOf(R.mipmap.imgeName));
file.getPath();

Android. How to load the picture from memory knowing its full path?

I saved the picture on phone from application. I found a file manager it and I made sure that it really remained. Further I try to load on its full path it by BitmapFactory.decodeFile() method transferring a full path to the picture, a way to pictures at me such there, I will give an example from application:
/storage/emulated/0/Android/data/com .example.home.page/files/2015218161530.jpg
But me jumps out Exception, what decoding is impossible since the file isn't found, what for nonsense? Thanks in advance

You can use this method this will work for you
just pass path of images(where your image is store and object reference of you ImageView as a second argument)
1st argument Path of images want ot display
2nd argument object reference of `ImageView`
public static void ShowPicture(String filePath, ImageView pic) {
File f = new File(filePath);
FileInputStream is = null;
try {
is = new FileInputStream(f);
} catch (FileNotFoundException e) {
Log.d("error: ",String.format( "ShowPicture.java file[%s]Not Found",fileName));
return;
}
Bitmap = BitmapFactory.decodeStream(is, null, null);
pic.setImageBitmap(bm);
}
please also put this permission in manifest file
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

try below code that might help you.
File f = new File(PathToFiles +yourFileName);
if (f.exists()) {
Drawable d = Drawable.createFromPath(f.getPath());
imageview.setImageDrawable(d);
}

How to get path of any file from my my application data folder

My application files are bellow, I want to get sharethis.png file in java code , What is syntax ?
I used this ...
Bitmap bMap = BitmapFactory.decodeFile("file:///android_asset/www/sharethis.png");
but not working

Try:
Bitmap shareThis = BitmapFactory.decodeResource(context.getResources(),
R.drawable.shareThis);

If you want to reference it from a JavaScript or html file in your assets folder, use file:///android_asset/www/sharethis.jpg.
Otherwise, according to this answer, this will list all the files in the assets folder:
AssetManager assetManager = getAssets();
String[] files = assetManager.list("");
This to open a certain file:
InputStream input = assetManager.open(assetName);

Try this:
try {
// get input stream
InputStream ims = getAssets().open("sharethis.png");
// load image as Drawable
Drawable d = Drawable.createFromStream(ims, null);
// set image to ImageView
mImage.setImageDrawable(d);
}
catch(IOException ex) {
Log.e("I/O ERROR","Failed")
}

Instead of using the assets dir, put the file into /res/raw , and you can then access it using the following URI: android.resource://com.your.packagename/" + R.raw.sharethis

Retrieve image path from assets folder

I have issue to retrieve image path from assets folder.
I have an image folder in assets folder. Within the folder i have three different folders.
Here is the code that i used:
String IntroImage1= "" + languageSelected + "/" + Intro1ImagePath + ".png" ;
try{
AssetManager mngr =getAssets();
InputStream BulletImgInput = mngr.open(IntroImage1);
//InputStream BulletImgInput = mngr.open("image/Malay/bullet.png");
Bitmap bitmapBullet = BitmapFactory.decodeStream(BulletImgInput);
BulletImage.setImageBitmap(bitmapBullet);
}catch(final IOException e){
e.printStackTrace();
}
I am wondering why can't i display the image? Because I have try to retrieve it through this code:
InputStream BulletImgInput = mngr.open("image/Malay/bullet.png");
It did retrieve the file, but with the string that i replaced in mngr.open it doesn't show up.
Really need you guys to help up.Thanks.

You don't need the AssetManager. You can do
BitmapFactory.decodeFile("file:///android_asset/image/Malay/bullet.jpg")
Though storing Images in the Assets is not the best way to go. You will not be able to take advantage of the Android resource management system. So unless you have a compelling reason to do this, I'd suggest that you take a look at using the res folder and the resources system.
Update: Explanation
The BitmapFactory has a method to decode a file via the decodeFile method. That's point one. Android lets you access a file in the assets folder via the file:///android_asset/{path} path. In your case, the Image at /image/Malay/bullet.jpg is the assets folder can be accessed via the the file:///android_asset/image/Malay/bullet.jpg.

Try this:
try {
// get input stream
InputStream ims = getAssets().open("avatar.jpg");
// load image as Drawable
Drawable d = Drawable.createFromStream(ims, null);
// set image to ImageView
mImage.setImageDrawable(d);
}
catch(IOException ex) {
Log.e("I/O ERROR","Failed when ..."
}
your BulletImage

String url = "file:///android_asset/NewFile.txt";
String url = "file:///android_asset/logo.png";
you can access any file....

InputStream BulletImgInput = mngr.open("file:///android_asset/image/Malay/bullet.png");
Maybe this could work for u.

May be problem is in missed image part of path?
String IntroImage1= "image/" + languageSelected + "/" + Intro1ImagePath + ".png" ;
instead of
String IntroImage1= "" + languageSelected + "/" + Intro1ImagePath + ".png" ;
Upd: Check values of languageSelected and Intro1ImagePath also.

Android get image path from drawable as string

Is there any way that I can get the image path from drawable folder in android as String. I need this because I implement my own viewflow where I'm showing the images by using their path on sd card, but I want to show a default image when there is no image to show.
Any ideas how to do that?

These all are ways:
String imageUri = "drawable://" + R.drawable.image;
Other ways I tested
Uri path = Uri.parse("android.resource://com.segf4ult.test/" + R.drawable.icon);
Uri otherPath = Uri.parse("android.resource://com.segf4ult.test/drawable/icon");
String path = path.toString();
String path = otherPath .toString();

based on the some of above replies i improvised it a bit
create this method and call it by passing your resource
Reusable Method
public String getURLForResource (int resourceId) {
//use BuildConfig.APPLICATION_ID instead of R.class.getPackage().getName() if both are not same
return Uri.parse("android.resource://"+R.class.getPackage().getName()+"/" +resourceId).toString();
}
Sample call
getURLForResource(R.drawable.personIcon)
complete example of loading image
String imageUrl = getURLForResource(R.drawable.personIcon);
// Load image
Glide.with(patientProfileImageView.getContext())
.load(imageUrl)
.into(patientProfileImageView);
you can move the function getURLForResource to a Util file and make it static so it can be reused

If you are planning to get the image from its path, it's better to use Assets instead of trying to figure out the path of the drawable folder.
InputStream stream = getAssets().open("image.png");
Drawable d = Drawable.createFromStream(stream, null);

I think you cannot get it as String but you can get it as int by get resource id:
int resId = this.getResources().getIdentifier("imageNameHere", "drawable", this.getPackageName());

First check whether the file exists in SDCard. If the file doesnot exists in SDcard then you can set image using setImageResource() methodand passing default image from drawable folder
Sample Code
File imageFile = new File(absolutepathOfImage);//absolutepathOfImage is absolute path of image including its name
if(!imageFile.exists()){//file doesnot exist in SDCard
imageview.setImageResource(R.drawable.defaultImage);//set default image from drawable folder
}
