import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class WallpaperScreenActivity extends ActionBarActivity {

    public static final int REQUEST_CODE = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.wallpaper_layout);

        // image resource
        ImageView img = (ImageView) findViewById(R.id.imageView1);
        img.setImageResource(R.drawable.pop);

        // call installed wallpaper app to set wallpaper on button click
        Button b1 = (Button) findViewById(R.id.button1);
        b1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View vx) {


                Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
                intent.addCategory(Intent.CATEGORY_DEFAULT);                
                intent.setDataAndType(uri.setreso, "image/jpeg");
                intent.putExtra("mimeType", "image/jpeg");
                this.startActivity(Intent.createChooser(intent, "Set as:"));

            }

        });

    }

}

those errors i got:

Description Resource    Path    Location    Type

uri cannot be resolved to a variable    WallpaperScreenActivity.java    /Wallpaper_Test/src/com/example/wallpaper_test  line 32 Java Problem

The method startActivity(Intent) is undefined for the type new View.OnClickListener(){} WallpaperScreenActivity.java    /Wallpaper_Test/src/com/example/wallpaper_test  line 34 Java Problem

i created a very simple app in which i am showing an image in image_view and i want to open this image in another app on button click.

Just remove this from this.startActivity(), just use startActivity() — joao2fast4u, Jul 27 '14 at 00:18
Your code is right, you just need to pass a valid Uri to the Intent. What is the Uri you want to pass? — joao2fast4u, Jul 27 '14 at 00:30
actually i want to pass image so i can open it with another app — user3739970, Jul 27 '14 at 06:57
i tried this: `Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setDataAndType(Uri.parse("android.resource://com.example.wallpaper_test/drawable/pop"),"image/*"); startActivity(intent);` and got unfortunately app stopped error — user3739970, Jul 27 '14 at 13:20

Try using the following Code..

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("file://" + "/sdcard/test.jpg"), "image/*");
startActivity(intent);

how do i pass image-view image to uri – user3739970 Jul 27 '14 at 07:17
You cannot pass imageview. if you want to show the image in your own app then you can use imageview to show the image inside your own app. – Umer Kiani Jul 27 '14 at 07:18
`intent.setDataAndType(Uri.parse("file://" + "/sdcard/test.jpg"), "image/*");` in this line it gets image from sd card location, but is there a way to get image source from drawable or get the image that is showing in imageview – user3739970 Jul 27 '14 at 07:22
Ok now i Get it yes there is a way. will edit question. – Umer Kiani Jul 27 '14 at 07:23
To Open Image in Drawable you will have to do something like Uri uri = Uri.parse("android.resource://your.package.here/drawable/image_name"); hope this helps :) now awaiting you to accept answer :) – Umer Kiani Jul 27 '14 at 07:29
according to your code i tried this `intent.setDataAndType(Uri.parse("android.resource://package com.example.wallpaper_test;/drawable/pop"), "image/*");` and got error unfortunately stopped – user3739970 Jul 27 '14 at 07:35
