I've created this demo that retrieve an image from the gallery and show it in an ImageView (after resampling the image itself) https://github.com/svappdroid/BitmapDemo
On a Galaxy Nexus I'm not able to open an image with dimension 4307x2894, logcat says "Bitmap Too Large to be uploaded in a texture"; the weird thing is that emulating the Galaxy Nexus I'm able to open the same image; why this behavior and how to solve it on the actual device?
The activity code is:
package com.example.bitmapdemo;
import java.io.FileNotFoundException;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.Toast;
public class MainActivity extends Activity {
public ImageView canvasImageView;
public Button selectImageButton;
public LinearLayout ll;
public Bitmap image;
//REQUEST CODE
public static final int SELECT_IMAGE_REQ_CODE = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ll = (LinearLayout) this.findViewById(R.id.LinearLayout1);
canvasImageView = (ImageView) this.findViewById(R.id.canvasImageView);
selectImageButton = (Button) this.findViewById(R.id.selectImageButton);
selectImageButton.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v)
{
Intent selectImageIntent = new Intent(Intent.ACTION_GET_CONTENT);
selectImageIntent.setType("image/*");
startActivityForResult(selectImageIntent, SELECT_IMAGE_REQ_CODE);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == SELECT_IMAGE_REQ_CODE)
{
switch(resultCode)
{
case(RESULT_OK):
Uri imageUri = data.getData();
try
{
int inSampleSize = calculateInSampleSize(imageUri);
image = resampleImage(imageUri, inSampleSize);
canvasImageView.setImageBitmap(image);
}
catch(FileNotFoundException e){}
}
}
}
public int calculateInSampleSize(Uri imageUri) throws FileNotFoundException
{
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inJustDecodeBounds = true;
BitmapFactory.decodeStream(getContentResolver().openInputStream(imageUri), null, opts);
int imageWidth = opts.outWidth;
int imageHeight = opts.outHeight;
int inSampleSize = 4;
//Get display dimension in order to calculate image ratio
DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int reqWidth = displayMetrics.widthPixels;
int reqHeight = displayMetrics.heightPixels;
if(imageHeight > reqHeight || imageWidth > reqWidth)
{
final int heightRatio = Math.round((float)imageHeight / (float) reqHeight);
final int widthRatio = Math.round((float) imageWidth / (float) reqWidth);
inSampleSize = heightRatio
And here is the xml code for the layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<ImageView
android:id="@+id/canvasImageView"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:layout_gravity="center"
android:src="@drawable/ic_launcher" />
<Button
android:id="@+id/selectImageButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/select_image_button" />
</LinearLayout>
