致命例外:ThumbnailManager-1 在将图像共享到 Intent 时
FATAL EXCEPTION: ThumbnailManager-1 while sharing images to Intent
我在使用 FileProvider 共享图像时遇到以下异常。以下是我以前的代码。
{
ArrayList<Uri> files = new ArrayList<Uri>();
files.add(getImageUriFromCache(context,bitmap,fileName));
}
private void startSharingIntent(ArrayList<Uri> files,String caption){
Intent i=new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
i.setType("image/png");
i.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
i.putExtra(Intent.EXTRA_SUBJECT, "my app share");
i.putParcelableArrayListExtra(Intent.EXTRA_STREAM, files);
i.putExtra(Intent.EXTRA_TEXT,caption);
i.putExtra(Intent.EXTRA_TITLE,caption);
context.startActivity(Intent.createChooser(i, "Tital"));
}
public Uri getImageUriFromCache(Context inContext, Bitmap inImage , String fileId) throws IOException{
File cachePath = new File(inContext.getFilesDir() , "images/");
cachePath.mkdirs(); // don't forget to make the directory
File newFile = new File(cachePath, "im"+fileId+"_post.png");
newFile.setReadable(true, false);
FileOutputStream stream = new FileOutputStream(newFile); // overwrites this image every time
inImage.compress(Bitmap.CompressFormat.PNG, 100, stream);
stream.close();
Uri contentUri = FileProvider.getUriForFile(inContext, "com.xx.xx.fileprovider", newFile);
return contentUri;
}
异常的详细堆栈跟踪如下。

当我选择要共享的电子邮件时,图像可以正确共享,但是当我 select 发送消息时,图像会失败。请协助。
根据消息来源,Android UriImage
class(彩信应用程序)会尝试读取您提供的图像的方向。它通过 运行 a query
在 Uri
你提供的 MediaStore.Images.ImageColumns.ORIENTATION
列中做到这一点。
我没有找到 FileProvider class 的最新来源,但这个较旧的 FileProvider.java 版本仅支持两个列名称:
OpenableColumns.DISPLAY_NAME
OpenableColumns.SIZE
如果请求这两列中的 none,它只会 return 一个空行(根本没有任何列)。
在您的情况下,空行会导致 MMS 应用程序在请求索引为 0
的列时崩溃。
那你能做什么?
我看到至少三个可能的选项。所有这些都涉及创建您自己的 FileProvider
的 Subclass,它会覆盖 query
方法。
这取决于您的目标和技能水平,哪一个最适合您。我尝试将它们从“简单”到“相当多的工作”列出。
检查 projection
数组,如果其中出现 DISPLAY_NAME
或 SIZE
以外的任何列,则抛出 IllegalArgumentException
。这应该有效,因为 MMS 应用程序似乎忽略了此异常。不过,这可能会破坏其他应用程序。
检查投影并在请求的 ORIENTATION
列后附加值 0
(表示图像不需要任何旋转)。
这里有一些(未经测试的)代码来实现这个:
@Override
public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder)
{
Cursor cursor = super.query(uri, projection, selection, selectionArgs, sortOrder);
if ( cursor == null &&
projection != null
&& projection.length == 1
&& MediaStore.Images.ImageColumns.ORIENTATION.equals(projection[0])) {
// query from MMS app, return a single row with a 0 value
final MatrixCursor matrixCursor = new MatrixCursor(projection, 1);
matrixCursor.addRow(new Integer[]{0});
cursor = matrixCursor;
}
return cursor;
}
检查投影并在请求的 ORIENTATION
列后附加来自 EXIF 标签的实际值(如果图像中存在)。
我在使用 FileProvider 共享图像时遇到以下异常。以下是我以前的代码。
{
ArrayList<Uri> files = new ArrayList<Uri>();
files.add(getImageUriFromCache(context,bitmap,fileName));
}
private void startSharingIntent(ArrayList<Uri> files,String caption){
Intent i=new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
i.setType("image/png");
i.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
i.putExtra(Intent.EXTRA_SUBJECT, "my app share");
i.putParcelableArrayListExtra(Intent.EXTRA_STREAM, files);
i.putExtra(Intent.EXTRA_TEXT,caption);
i.putExtra(Intent.EXTRA_TITLE,caption);
context.startActivity(Intent.createChooser(i, "Tital"));
}
public Uri getImageUriFromCache(Context inContext, Bitmap inImage , String fileId) throws IOException{
File cachePath = new File(inContext.getFilesDir() , "images/");
cachePath.mkdirs(); // don't forget to make the directory
File newFile = new File(cachePath, "im"+fileId+"_post.png");
newFile.setReadable(true, false);
FileOutputStream stream = new FileOutputStream(newFile); // overwrites this image every time
inImage.compress(Bitmap.CompressFormat.PNG, 100, stream);
stream.close();
Uri contentUri = FileProvider.getUriForFile(inContext, "com.xx.xx.fileprovider", newFile);
return contentUri;
}
