Android的画廊在奇巧返回不同的URI Intent.ACTION_GET_CONTENT [英] Android Gallery on KitKat returns different Uri for Intent.ACTION_GET_CONTENT

问题描述

奇巧之前（或新的画廊前） 在 Intent.ACTION_GET_CONTENT 返回 一个URI这样的 内容：//媒体/外部/图片/媒体/ 3951

Before Kitkat (or before the new Gallery) the Intent.ACTION_GET_CONTENT returned a Uri like this content://media/external/images/media/3951.

使用ContentResolver的和quering为 MediaStore.Images.Media.DATA 返回的文件的URL。

Using the ContentResolver and quering for MediaStore.Images.Media.DATA returned the file URL.

在奇巧但是图库返回的URI（通过最后）是这样的：

In Kitkat however the Gallery returns a Uri (via "Last") like this:

content://com.android.providers.media.documents/document/image:3951

如何来处理呢？

How to handle this?

推荐答案

试试这个：

if (Build.VERSION.SDK_INT <19){
    Intent intent = new Intent(); 
    intent.setType("image/jpeg");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, getResources().getString(R.string.select_picture)),GALLERY_INTENT_CALLED);
} else {
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType("image/jpeg");
    startActivityForResult(intent, GALLERY_KITKAT_INTENT_CALLED);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode != Activity.RESULT_OK) return;
    if (null == data) return;
    Uri originalUri = null;
    if (requestCode == GALLERY_INTENT_CALLED) {
        originalUri = data.getData();
    } else if (requestCode == GALLERY_KITKAT_INTENT_CALLED) {
        originalUri = data.getData();
        final int takeFlags = data.getFlags()
                & (Intent.FLAG_GRANT_READ_URI_PERMISSION
                | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
        // Check for the freshest data.
        getContentResolver().takePersistableUriPermission(originalUri, takeFlags);
    }

    loadSomeStreamAsynkTask(originalUri);

}

可能需要

@燮pressLint（NewApi）

@SuppressLint("NewApi")

为

takePersistableUriPermission

takePersistableUriPermission
