Accessing Android native gallery via an intent
How can I get a user to select from the native gallery in Android, rather than other gallery-like applications such as ASTRO File Manager?
The following code gives a list of activities that can select an image:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
List<ResolveInfo> infos = activity.getPackageManager().queryIntentActivities(intent, 0);
If I then do something like this:
activity.startActivityForResult(Intent.createChooser(intent, "Select Picture"), REQUEST_CHOOSE_IMAGE);
then if the user has more than one application that can 开发者_Go百科act like a gallery (such as ASTRO File Manager), s/he is prompted to select one of them, with no "set as default" option.
I don't want the user to be prompted to choose between them each time, so I'd like to just use the native gallery.
The hacky code sample below uses a whitelist to test for known native gallery names:
for (ResolveInfo info : infos) {
if ( 0==info.activityInfo.name.compareTo("com.cooliris.media.Gallery")
|| 0==info.activityInfo.name.compareTo("com.htc.album.CollectionsActivity")
) {
// found the native gallery
doSomethingWithNativeGallery();
}
}
Feels kinda dirty. Is there a better way? I suspect I'm missing something in my intent.
I didn't get last part of your code.
To start the native gallry what i did is -
public void upload(){
Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/jpg");
photoPickerIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/Pictures/image.jpg"));
startActivityForResult(photoPickerIntent, 1);
}
Call the upload() where you like to start the native gallery.
Then to get that image info i did -
/**
* Retrieves the returned image from the Intent, inserts it into the MediaStore, which
* automatically saves a thumbnail. Then assigns the thumbnail to the ImageView.
* @param requestCode is the sub-activity code
* @param resultCode specifies whether the activity was cancelled or not
* @param intent is the data packet passed back from the sub-activity
*/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == RESULT_CANCELED) {
return;
}
else if(resultCode == RESULT_OK) {
Uri uri = intent.getData();
String path = getPath(uri);
Log.i("PATH", path);
data = path;
return;
}
uplad();
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
If you wouldn't get your answer, clear what you like to do
