Android – Getting an image from Gallery on from the Picasa//Google + synced folders doesn’t work

androidandroid-contentproviderandroid-intent

I am trying to get an image from the gallery app from one of the folders from the Google+ synced photos. After selecting the image, the Uri is being passed back correctly. But when I try to get the actual path of that image on the storage device, so that I can use it, it crashes. The problem seems to be specifically with the picasa content provider.

Tested on Nexus S and Nexus 7, and other devices as well.

E/AndroidRuntime(14572): java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, data=Intent { dat=content://com.google.android.gallery3d.provider/picasa/item/5427003652908228690 }}

Here, the dat field seems to be correctly passing the Uri, but when I try to fetch the image's location, it crashes with the following error.

W/GalleryProvider(14381): unsupported column: _data

Seems that the content provider for Picasa albums doesn't have a _data field.

The code for getting the location is:

// imageUri is the Uri from above.
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = context.getContentResolver().query(imageUri, proj,null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();

String filePath = cursor.getString(column_index);
cursor.close();

The only columns that seem to be supported for this image are:
[user_account, picasa_id, _display_name, _size, mime_type, datetaken, latitude, longitude, orientation]

How do we get the actual location of this image. And if we are not supposed to work with this image, these images shouldn't be shown to the user in the first place.

The Intent to launch the gallery app is:

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);

I wasted now lots of hours and now i found a solution which works in all cases without any magic downloading in special threads or something. The following method returns a stream from the content which the user selected and this works with everything in the wild.

FileInputStream getSourceStream(Uri u) throws FileNotFoundException {
    FileInputStream out = null;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        ParcelFileDescriptor parcelFileDescriptor =
                mContext.getContentResolver().openFileDescriptor(u, "r");
        FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
        out = new FileInputStream(fileDescriptor);
    } else {
        out = (FileInputStream) mContext.getContentResolver().openInputStream(u);
    }
    return out;
}

I have faced the exact same problem,
Finally the solution I found, was to launch an ACTION_GET_CONTENT intent instead of an ACTION_PICK, then make sure you provide a MediaStore.EXTRA_OUTPUT extra with an uri to a temporary file. Here is the code to start the intent :

public class YourActivity extends Activity {
    File mTempFile;
    int REQUEST_CODE_CHOOSE_PICTURE = 1;

    (...)
    public showImagePicker() { 
        mTempFile = getFileStreamPath("yourTempFile");
        mTempFile.getParentFile().mkdirs();
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null);
        intent.setType("image/*");
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mTempFile));
        intent.putExtra("outputFormat",Bitmap.CompressFormat.PNG.name());                       
        startActivityForResult(intent,REQUEST_CODE_CHOOSE_PICTURE);
    }

    (...)
}

You might need to mTempFile.createFile()

Then in onActivityResult, you will be able to get the image this way

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    case REQUEST_CODE_CHOOSE_PICTURE:
                Uri imageUri = data.getData();
                if (imageUri == null || imageUri.toString().length() == 0) {
                    imageUri = Uri.fromFile(mTempFile);
                    file = mTempFile;
                }
                                    if (file == null) {
                                       //use your current method here, for compatibility as some other picture chooser might not handle extra_output
                                    }
}

Hope this helps

Then you should delete your temporary file on finish (it is in internal storage as is, but you can use external storage, I guess it would be better).

Android – How to open the Google Play Store directly from the Android application

You can do this using the market:// prefix.

Java

final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException anfe) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
}

Kotlin

try {
    startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$packageName")))
} catch (e: ActivityNotFoundException) {
    startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=$packageName")))
}

We use a try/catch block here because an Exception will be thrown if the Play Store is not installed on the target device.

NOTE: any app can register as capable of handling the market://details?id=<appId> Uri, if you want to specifically target Google Play check the Berťák answer
