这是我获取的文件路径 content://com.tencent.mm.external.fileprovider/attachment/1_双模vd108 87.pdf

获取文件的方法

File destFile = new File(getFilesDir(), "copied_file.pdf"); // 修改文件名和类型
try (
        InputStream inputStream = getContentResolver().openInputStream(uri);
        OutputStream outputStream = new FileOutputStream(destFile)) {
    Log.d(Constents.LOGOUTCS, "inputStream" + inputStream);
    Log.d(Constents.LOGOUTCS, "outputStream" + outputStream);
    byte[] buffer = new byte[1024];
    int bytesRead;
    while ((bytesRead = inputStream.read(buffer)) != -1) {
        outputStream.write(buffer, 0, bytesRead);
    }
} catch (Exception e) {
    e.printStackTrace();
  
}

在 getContentResolver().openInputStream(uri)

报错如下

java.lang.SecurityException: Permission Denial: reading android.support.v4.content.FileProvider uri content://com.tencent.mm.external.fileprovider/attachment/1_双模vd108 87.pdf from pid=26273, uid=10316 requires the provider be exported, or grantUriPermission()
