英文:
IllegalArgumentException: Invalid column latitude
问题
根据文档中的说明,我尝试使用ContentResolver
查询文件大小,代码如下:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == video_request_code) {
if (resultCode == RESULT_OK) {
Uri uri = data.getData();
String[] projection = {OpenableColumns.SIZE, OpenableColumns.DISPLAY_NAME};
Cursor cur = getContentResolver().query(uri, projection, null, null, null);
try {
if (cur != null && cur.moveToFirst()) {
int sizeIndex = cur.getColumnIndex(OpenableColumns.SIZE);
Log.e("size", "" + cur.getLong(sizeIndex));
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (cur != null)
cur.close();
}
}
}
}
然后出现以下错误信息:
java.lang.IllegalArgumentException: Invalid column latitude
at android.app.ActivityThread.deliverResults(ActivityThread.java:4845)
...
at com.my.package.MainActivity.onActivityResult(MainActivity.java:146)
...
虽然崩溃指向了Cursor cur = getContentResolver().query(uri, null, null, null, null);
,但如您所见,代码中并未查询纬度列(latitude column)。实际上,在崩溃发生时,并没有查询任何列。
仅当在运行 Android 10 的设备上从 Google 相册选择文件时,我才能复现这个问题。
我的问题:
为什么会出现这种情况,我应该如何解决?
编辑:
我尝试传递了列的投影(projection)。为了测试,我传递了以下内容:
String[] projection = {OpenableColumns.SIZE, OpenableColumns.DISPLAY_NAME};
Cursor cur = getContentResolver().query(uri, projection, null, null, null);
但我仍然收到相同的错误消息。
英文:
Following the documentation
I tried querying ContentResolver
to get the file size, like this:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == video_request_code) {
if (resultCode == RESULT_OK) {
Uri uri = data.getData();
Cursor cur = getContentResolver().query(uri, null, null, null, null);
try {
if (cur != null && cur.moveToFirst()){
if (uri.getScheme() != null){
if (uri.getScheme().equals("content")) {
int sizeIndex = cur.getColumnIndex(OpenableColumns.SIZE);
Log.e("size", ""+cur.getLong(sizeIndex));
}else if (uri.getScheme().equals("file")) {
File ff = new File(uri.getPath());
Log.e("size", ""+ff.length());
}
}
}
}catch (Exception e){
e.printStackTrace();
}
finally {
if (cur != null)
cur.close();
}
}
}
}
Then I get the following error:
java.lang.IllegalArgumentException: Invalid column latitude

...
The crash is pointing to Cursor cur = getContentResolver().query(uri, null, null, null, null);
, but as you can see, I'm not querying the latitude column. In fact, at the time of the crash, I have not queried any column.
I could only reproduce this when selecting a file from Google Photo on a device running Android 10.
My Question:
Why is this happening and how can I overcome it?
Edit:
I tried passing the projection of the columns. To test, I passed the following:
String[] projection = {OpenableColumns.SIZE, OpenableColumns.DISPLAY_NAME};
Cursor cur = getContentResolver().query(uri, projection, null, null, null);
But I still get the same error.

我在Android 10+中遇到了相同的问题。这个问题是由Android 10引入的分区存储所导致的。
解决方案:
我对这个问题的解决方案是从Uri创建一个输入流。请查看下面的代码片段。
fun getVideoRealPath(
context: Context, uri: Uri
): File? {
val contentResolver = context.contentResolver ?: return null
// 在应用程序数据目录内创建文件路径
val filePath = (context.applicationInfo.dataDir + File.separator
+ System.currentTimeMillis())
val file = File(filePath)
try {
val inputStream = contentResolver.openInputStream(uri) ?: return null
val outputStream: OutputStream = FileOutputStream(file)
val buf = ByteArray(1024)
var len: Int
while (inputStream.read(buf).also { len = it } > 0) outputStream.write(buf, 0, len)
outputStream.close()
inputStream.close()
} catch (ignore: IOException) {
return null
}
return file
}
英文:
I got the same issue in Android 10+. This issue is due to scoped storage which is introduced in Android 10.
Solutions:
My solution to this problem is to create an input stream from a Uri. Check the code snippet below.
fun getVideoRealPath(
context: Context, uri: Uri
): File? {
val contentResolver = context.contentResolver ?: return null
// Create file path inside app's data dir
val filePath = (context.applicationInfo.dataDir + File.separator
+ System.currentTimeMillis())
val file = File(filePath)
try {
val inputStream = contentResolver.openInputStream(uri) ?: return null
val outputStream: OutputStream = FileOutputStream(file)
val buf = ByteArray(1024)
var len: Int
while (inputStream.read(buf).also { len = it } > 0) outputStream.write(buf, 0, len)
outputStream.close()
inputStream.close()
} catch (ignore: IOException) {
return null
}
return file
}

我找到了解决方案。
Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
当我使用这个时,会显示问题。
Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
galleryIntent.setType("video/*");
galleryIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
galleryIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, false);
galleryIntent.addCategory(Intent.CATEGORY_OPENABLE);
这个方法效果很好,你将会得到大小和临时文件路径。
请参考这些链接。
祈祷一切顺利。
英文:
I found the solution
Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
When I use this, it shows the issue.
Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
galleryIntent.setType("video/*");
galleryIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
galleryIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, false);
galleryIntent.addCategory(Intent.CATEGORY_OPENABLE);
This works well and you will get the size and temporary file path.
