Questions:

I am trying out on Android 2.3 and above phones. The phones/tablet that I have are

Samsung S (Android 2.3.5)
LG phone (Android 2.3.3)
Nexus One (Android 2.3.6)
Android Tablet (Android 4.0.3)

I tried the following:

Intent intent = new Intent(Intent.ACTION_VIEW, null);
intent.setType("image/*");
startActivity(intent);

So I tried the following:

Intent intent1= new Intent("android.intent.action.MAIN", null);
intent1.addCategory("android.intent.category.APP_GALLERY");
Intent intent2 = Intent.createChooser(intent1, "Gallery");
startActivity(intent2);

Again this works just fine with phones that are above/equalto 4.0 version. On 4.0 below phones it gives alert notification by saying:

"No application can perform this action"

Can somebody help me out with opening the Gallery from pressing a button from my app?

How to&Answers:

I figured out the way..

 Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(
 "content://media/internal/images/media")); 
 startActivity(intent); 

This piece of code just opened the gallery without any issues. Could get it working on all versions!

Thought to put it as answer for people who are looking to open a Gallery on all versions.

Thanks Guys! 🙂

Answer:

Try This out

btnGallery.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, ""), PICK_IMAGE);
    }
});

UPDATE onActivityResult

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode != Activity.RESULT_CANCELED) {
        if (requestCode == PICK_IMAGE) {
            Uri selectedImageUri = data.getData();
        } 
    }
}

UPDATE TO OPEN GALLERY APP

Intent galleryIntent = new Intent(Intent.ACTION_VIEW, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivity(galleryIntent);

Answer:

Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(
                    Intent.createChooser(intent, "Complete action using"),
                    PICK_FROM_FILE);
