如果我使用的ContentProvider在我的应用我得到错误,如‘不幸的是相机已停止’后Result_ok.This是我的代码:不幸相机已停止”,而使用内容提供商
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, MyFileContentProvider.CONTENT_URI);
startActivityForResult(i, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
如何解决这个?我不想保存的图像在SD卡
这是我MyFileContentProvider类:
public class MyFileContentProvider extends ContentProvider {
public static final Uri CONTENT_URI = Uri.parse("content://com.example.user.studentadmission/");
private static final HashMap<String, String> MIME_TYPES = new HashMap<String, String>();
static {
MIME_TYPES.put(".jpg", "image/jpeg");
MIME_TYPES.put(".jpeg", "image/jpeg");
}
@Override
public boolean onCreate() {
try {
File mFile = new File(getContext().getFilesDir(), "student.jpg");
if(!mFile.exists()) {
mFile.createNewFile();
}
getContext().getContentResolver().notifyChange(CONTENT_URI, null);
return (true);
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
@Override
public String getType(Uri uri) {
String path = uri.toString();
for (String extension : MIME_TYPES.keySet()) {
if (path.endsWith(extension)) {
return (MIME_TYPES.get(extension));
}
}
return (null);
}
@Override
public ParcelFileDescriptor openFile(Uri uri, String mode)
throws FileNotFoundException {
File f = new File(getContext().getFilesDir(), "student.jpg");
if (f.exists()) {
return (ParcelFileDescriptor.open(f,
ParcelFileDescriptor.MODE_READ_WRITE));
}
throw new FileNotFoundException(uri.getPath());
}
@Override
public Cursor query(Uri url, String[] projection, String selection,
String[] selectionArgs, String sort) {
throw new RuntimeException("Operation not supported");
}
@Override
public Uri insert(Uri uri, ContentValues initialValues) {
throw new RuntimeException("Operation not supported");
}
@Override
public int update(Uri uri, ContentValues values, String where,
String[] whereArgs) {
throw new RuntimeException("Operation not supported");
}
@Override
public int delete(Uri uri, String where, String[] whereArgs) {
throw new RuntimeException("Operation not supported");
}
}
