我使用aFileChooser提供的代码来获取我的应用程序中的共享图像。图库中的图片工作正常,但如果我在Google Chrome中使用图片并尝试分享图片,它会给我一个NPE,因为我的imagePath
为空。无法接收共享图像 - Android 6.0
String imagePath = getPath(getActivity(), imageUri);
我uri
被认定为MediaStore(和)一般从这个代码:
else if ("content".equalsIgnoreCase(uri.getScheme())) {
if (isGooglePhotosUri(uri))
return uri.getLastPathSegment();
return getDataColumn(context, uri, null, null);
}
但是里面getDataColumn()
我的光标转储如下:
08-24 12:00:58.196 13186 13256 ReceivePhotos D Cursor is: >>>>> Dumping cursor [email protected]
08-24 12:00:58.196 13186 13256 ReceivePhotos D 0 {
08-24 12:00:58.196 13186 13256 ReceivePhotos D _data=null
08-24 12:00:58.196 13186 13256 ReceivePhotos D }
08-24 12:00:58.196 13186 13256 ReceivePhotos D <<<<<
08-24 12:00:58.196 13186 13256 ReceivePhotos D Cursor column index is: 0
getDataColumn()方法:
public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs,null);
Log.d("ReceivePhotos", " Cursor is: " + DatabaseUtils.dumpCursorToString(cursor));
if (cursor != null && cursor.moveToFirst()) {
final int column_index = cursor.getColumnIndexOrThrow(column);
Log.d("ReceivePhotos", " Cursor column index is: " + column_index);
return cursor.getString(column_index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}

为什么要那样做所有的工作? [ContentResolver.openInputStream()](https://developer.android.com/reference/android/content/ContentResolver.html#openInputStream(android.net.Uri))适用于任何URI。 – ianhanniballake
