How to get id of an image of a clicked cardview from view element

In my layout applications I have a card view where each card contains a representations of an application.
In each card there are: the name of an applications, a description and his icon.
#Override
public void onBindViewHolder(#NonNull final AdapterForCard.ViewHolder holder, final int position) {
holder.iv.setImageDrawable(myCards.get(position).getIcon());
holder.titleView.setText(myCards.get(position).getTitle());
holder.descView.setText(myCards.get(position).getInfo());
holder.cv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(holder.cv.getContext(), "Cliccked card: "+(holder.titleView.getText()), Toast.LENGTH_SHORT).show();
Context context = v.getContext();
Intent i = new Intent(context,DetailsAppActivity.class);
//First Convert Image into Byte Array
// and then pass into Intent and in next activity
// get byte array from Bundle and Convert into Image(Bitmap) and set into ImageView
// holder.iv.getId_ 2131296339 v.getId_ 2131296348.
//
int id1 = holder.iv.getId();
int id2 = v.getId();
int id3 = R.id.iconView;
System.out.println("id1_ "+id1);
System.out.println("id2_ "+id2);
System.out.println("id3_ "+id3);
Bitmap btm = BitmapFactory.decodeResource(v.getResources(),id1);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
System.out.println("bitmap is null ? "+(btm==null));
btm.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
i.putExtra("title", ""+holder.titleView.getText());
i.putExtra("title", ""+holder.titleView.getText());
i.putExtra("icon",byteArray);
context.startActivity(i);
}
});
}
I want pass the three date to my DetailsActivity, but i have the follow error:
id1_ 2131296339
id2_ 2131296348
id3_ 2131296339
bitmap is null ? true

How to set id correctly?

Update 2
As you told that you don't have resource id. You have application package, and have to get application icon, so you can pass package name of that app. And in next activity just get application icon.
Important Edit
I did not notice that you are using Drawable object instead of using an int id. There is no need to store drawable objects in List. So do the following.
First change type of icon as int (Resource id).
list.setIconId(R.drawable.ic_launcher)
BitmapFactory.decodeResource(getResources(), myCards.get(position).getIconId());
set ImageView image by below method.
Old solution is also edited for same.
holder.iv.setImageResource(myCards.get(position).getIconId());
Solution
Just change holder.iv.getId(); with myCards.get(position).getIconId()
Bitmap btm = BitmapFactory.decodeResource(v.getResources(),myCards.get(position).getIconId());
Reason of crash
Because holder.iv.getId() returns you ImageView id NOT drawable resource id.
Suggestion (must use)
Pass resource id instead of passing bitmap array. There is no need to pass byte array of bitmap.
i.putExtra("icon",myCards.get(position).getIconId());
in next activity
imageView.setImageResource(getIntent().getIntExtra("icon",0));
Isn't it simple :)

well your stream is null because you are giving id instead of position. use this one
mCard.get(position).getIcon()

NullPointerException on getResources().getDisplayMetrics().density

Context
I'm working on a small test code right now. It selects an image, resizes it to fit the screen based on the screen density. While it does this, it makes a copy of the image at the size it would be in an xxhdpi display, and the converts into a Bitmap, then into a String. The String is then carried through an Intent to the next screen where the String is turned back into a Bitmap and then placed in an ImageButton.
This worked fine until I added in a chunk of code to resize the image given by the string based on the density. The odd thing is I copied and pasted the DPI() method from another activity and there were no issues in that activity.
Code
package com.example.zachary.imagetesting.Resizing;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.util.Base64;
import android.view.View;
import android.widget.ImageButton;
import android.widget.TextView;
import com.example.zachary.imagetesting.R;
public class PictureDecoded extends Activity {
TextView Text;
ImageButton Image;
String string;
Bitmap picture;
public float DPI(){return getResources().getDisplayMetrics().density;}
float dpi = DPI() * 180;
int size = (int) dpi;
public Bitmap Pic(String string){
try{
byte[] b = Base64.decode(string, Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(b, 0, b.length);
return bitmap;
} catch (Exception e) {
e.getMessage();
return null;
}
}
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.resizing);
string = getIntent().getStringExtra("String");
Image = (ImageButton) findViewById(R.id.image);
Text = (TextView) findViewById(R.id.text);
picture = Pic(string);
Image.setImageBitmap(Bitmap.createScaledBitmap(picture,size,size,false));
}
public void next(View view){ }
// I also tried addring DPI() here as well to no success.
//public float DPI(){return getResources().getDisplayMetrics().density;}
}

The large block of text is the String converted from Bitmap that was passed to the Activity. I left it in just in case it was useful. The line before the large block of text was the button click that started the intent to the activity which crashes due to NullPointerException.
I can add the other activities on request, but since it worked before I tried resizing based on screen density I didn't feel it was needed.

An Activity's base Context won't have been setup until after onCreate() has finished executing. Simply move the initialization of dpi to onCreate() after super.onCreate() has been called.

It works perfect for Android 5.0 and higher versions. But when i try with 4.2.2 version, that error occure. How can i fix this problem ?
Thanks in advice

This is very common error once you deal with bitmap. Converting bitmap directly from URL is not a good practice. You should use bitmap BitmapFactory.Options feature provided by android by which you can get the size of the bitmap without even creating a bitmap. Now you have to use insamplesize of BitmapFactory Options and re size the images. I guess the size and the quality of image is too high and that's why when you are converting it into bitmap it gives you out of memory. Each Android app has max 50 mb of RAM to use once it cross beyond that limit android system throws out of memory exception. However we can manage it by making an entry of an attribute in manifest in application tag largeHeap to true.
The best practice to deal with android bitmap is available on developer site. You can click here
Note:- largeHeap feature will work only from OS level 3.0 and above.

Getting java.lang.OutOfMemoryError when trying to run android app

Hi I am trying to create an android application to display images so that you can click on a 'next' button and then the next image shows. So far I have this method
public void buttonClick(){
imgView = (ImageView)findViewById(R.id.imgView);
buttonS = (Button)findViewById(R.id.button);
buttonS.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
current_image_index++;
current_image_index = current_image_index % images.length;
imgView.setImageResource(images[current_image_index]);
}
}
);
}
However when I try to run this, I get a java.lang.OutOfMemoryError when I click the 'next' button twice. Am I doing something wrong? My image array looks like this:
int[] images = {R.drawable.img};
I have tried changing the Manifest file to include
android:largeHeap="true"
This is where I set the variables and call the method above
public class MainActivity extends AppCompatActivity {
private static ImageView imgView;
private static Button buttonS;
private int current_image_index;
int[] images = {R.drawable.dog,R.drawable.img};
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonClick();
}

It is because the assigned heap for the application to handle the memory for all the images is low. You can increase it in the Android manifest file.
specify
android:largeHeap="true"
as a property of <application> tag
eg:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:largeHeap="true"
android:theme="#style/AppTheme" >
and see if that fixes the issue.
One option is to scale down the images before you display it.
Recycle the ImageView before you add the new image (But this will not hold up if the image is very large).

createBitmap throws outOfMemory exception very often

my app is throwing outofmemory exceptions to lots of people using it. my app creates a bitmap of the current screen then animates it to transition between pages.

the code that creates the bitmap
public static Bitmap loadBitmapFromView(View v) {
Bitmap bitmap;
v.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v.getDrawingCache());
bitmap.setHasAlpha(false);
v.setDrawingCacheEnabled(false);
return bitmap;
}
the code that animates the bitmap
public void mainMenu(View view) {
$isonfirstpage = 0;
$isonmainmenu = 1;
$isonpremiummenu = 0;
final RelativeLayout backgroundLayout = (RelativeLayout) findViewById(R.id.activity_background);

final ImageView screenie = new ImageView(getApplicationContext());
screenie.setImageDrawable(d);
backgroundLayout.addView(newLayout);
backgroundLayout.addView(screenie);
screenie.animate()
.translationY(backgroundLayout.getHeight())
.setDuration(300);
new Handler().postDelayed(new Runnable() {

}, 1500);
}

when ever the Bitmap size is huse then you will get OutOfMemory Exception you can decode/scale the bitmap when ever you are setting it to the imageview.
public Bitmap decodeUri(Uri path) throws FileNotFoundException
{
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(getContentResolver().openInputStream(path),null,o);
int REQUIRED_SIZE = 100;
int width_temp = o.outWidth;
int height_temp = o.outHeight;
int scale = 1;
while (true)
{
if(width_temp/2 < REQUIRED_SIZE || height_temp/2<REQUIRED_SIZE)
{
break;
}
width_temp/=2;
height_temp/=2;
scale*=2;
}
BitmapFactory.Options o1 =new BitmapFactory.Options();
o1.inSampleSize = scale;
return BitmapFactory.decodeStream(getContentResolver().openInputStream(path),null,o1);
}
you can covert your image path to Uri as follows
decodeUri(Uri.fromFile(new File("your file path")))
