Android 4.4 (KitKat) 上的 Android Gallery 为 Intent.ACTION_GET_CONTENT 返回不同的 URI [英] Android Gallery on Android 4.4 (KitKat) returns different URI for Intent.ACTION_GET_CONTENT

问题描述

在 KitKat 之前(或在新画廊之前)Intent.ACTION_GET_CONTENT 返回了一个像这样的 URI

Before KitKat (or before the new Gallery) the Intent.ACTION_GET_CONTENT returned a URI like this

content://media/external/images/media/3951.

content://media/external/images/media/3951.

使用 ContentResolver 并查询MediaStore.Images.Media.DATA 返回文件 URL.

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

然而，在 KitKat 中，画廊返回一个 URI(通过Last")，如下所示:

In KitKat however the Gallery returns a URI (via "Last") like this:

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

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

我该如何处理?

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

@SuppressLint("NewApi")

@SuppressLint("NewApi")

为了

获取PersistableUriPermission

takePersistableUriPermission
