Get image from drawable by path

I am trying to get image that inside drawable folder by path
so i try this but not working
String path = "android.resource:///" + BuildConfig.APPLICATION_ID + "/drawable/logo_ataturk";
File imgFile = new File(path);
if (imgFile.exists()) {
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView imgLogo = findViewById(R.id.imageView_logo);
imgLogo.setImageBitmap(myBitmap);
}

I found this simplest solution
Uri path = Uri.parse("android.resource://" + BuildConfig.APPLICATION_ID + "/drawable/logo_ataturk");
ImageView imgLogo = findViewById(R.id.imageView_logo);
imgLogo.setImageURI(path);

Resources are not files on the device. They are files on your developer machine, nothing more.
You can replace all of this code with:
ImageView imgLogo = findViewById(R.id.imageView_logo);
imgLogo.setImageResource(R.drawable.logo_ataturk);

Drawable drawable = getResources().getDrawable(getResources()
.getIdentifier($name_of_the_image, "drawable", getPackageName()));
or
Bitmap myBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.large_icon);
imgLogo.setImageBitmap(myBitmap);

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();

setImageBitmap gets Syntax Errors

I am trying to take a Bitmap and display it in an ImageView.
ImageView iv = new ImageView(this);
Bitmap bMap = BitmapFactory.decodeFile("/res/drawable/" + imageFileName);
iv.setImageBitmap(bMap);
That's my code for it. I create an ImageView and a Bitmap. I want to display my Bitmap in my ImageView. But I always get these two errors on the iv.setImageBitmap(bMap); statment
Syntax error on token "bMap", VariableDeclaratorId expected after this token
Syntax error on token(s), misplaced construct(s)
Does anybody has an idea why this happens and what i have to change?

In OP's pastebin code I've found the following snippet:
String imageFileName =getIntent().getStringExtra("imageFileName");
//String bildquelle = "R.drawable." + imageFileName;
public class ImageChange extends Activity {
ImageView iv = new ImageView(this);
String bildquelle = "R.drawable." + imageFileName;
int id = getResources().getIdentifier(bildquelle, "drawable", getPackageName());
Bitmap bMap = BitmapFactory.decodeResource(getResources(), id);
//Bitmap bMap = BitmapFactory.decodeFile("/res/drawable/" + imageFileName);
iv.setImageBitmap(bMap);
}
There are a couple of problems with this including:
The code is not inside a method body.
The code is a Activity subclass.
The code improperly calls getResources().getIdentifier(...).
Instead of the above code I suggest MERGING the rest of activity with the following:
public class BildAnzeigen extends ActionBarActivity {
ImageView iv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bild_anzeigen);
iv = (ImageView) findViewById(R.id.my_image_view); // replace the id with the one from layout definition
handleIntent(getIntent());
}
private void handleIntent(Intent intent) {
String imageFileName = intent.getStringExtra("imageFileName");
int id = getResources().getIdentifier(imageFileName, "drawable", null);
Bitmap bMap = BitmapFactory.decodeResource(getResources(), id);
iv.setImageBitmap(bMap);
}
}
Note: This will not work if the images are not compiled within your apk. There's no way to add anything to drawables after building. It just doesn't work that way.

SkImageDecoder:factory returned null

I am trying to get the image from sdcard to display it in an imageview in android. Its showing error as SkImageDecoder:factory returned null in android emulator2.2. Here is my code to retrieve image from SDcard to imageview in android.
File imgFile = new File("/sdcard/wm.png");
if (imgFile.exists()) {
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView myImage = (ImageView) findViewById(R.id.imageView1);
myImage.setImageBitmap(myBitmap);
}
Please resolve this issue.

Use Environment.getExternalStorageDirectory() or Environment.getExternalStoragePublicDirectory instead of hard coding the path of the sd card (i.e "/sdcard/wm.png").

Android: Displaying .jpg image from sdcard using ImageView

I am trying to display a .jpg from my sd card into an imageview in my layout. I dont get any errors, but nothing gets displayed. I would appreciate any help. Thanks
EDIT:
layout1 = (LinearLayout) findViewById(R.id.layout1Activity);
String imgFile = Environment.getExternalStorageDirectory() + "/Apple.jpg";
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile);
ImageView myImage = new ImageView(this);
myImage.setImageBitmap(myBitmap);
layout1.addView(myImage);

do NOT access the SD card directly, try accessing it trough Environment. Like this:
String imageDir = Environment.getExternalStorageDirectory()+"/apple.jpg";
and then you can call BitmapFactory:
Bitmap myBitmap = BitmapFactory.decodeFile(imageDir);
