如何在Uri.parse中使用FileProvider（file：//＆＃34; + filex.toString（））＆amp; Java.lang.RuntimeException接收BroadCast Intent时出错

Question

如何使用Route::post('test', ['as' => 'test', 'uses' => 'MainController@test']); 在FileProvider中没有收到错误？ 我已经尝试了android API >= 24，但它仍然出现错误......
这是我的源代码

FileProvider

首次登录

if(vid.equals("")) {
    inFileName = img.substring(img.lastIndexOf('/') + 1);

    File sdcard = Environment.getExternalStorageDirectory();
    File filex = new File(sdcard, inDir + "/" + "IMAGE_" + inFileName);
    if(filex.exists()) {
        if (inDialog.isShowing())
            inDialog.dismiss();

        Uri uri = Uri.parse("file://" + filex.toString());
        Intent i = new Intent();
        i.setAction(Intent.ACTION_VIEW);
        i.setDataAndType(uri, "image/*");
        inContext.startActivity(i);
    } else {
        inTmp = Uri.parse(img);
        Image_DownloadId = DownloadData(inTmp, "IMAGE_" + inFileName);
    }
}

由于使用android.os.FileUriExposedException: file:///storage/emulated/0/Images/IMAGE_26072028_383759662086144_8624202031520808960_n.jpg exposed beyond app through Intent.getData() 并且需要使用android api >= 24而导致此错误，因此我尝试使用它。 由于使用FileProvider方法，这一行有点令人困惑 toString

这是我想要做的事情

Uri.parse("file://" + filex.toString())

应用程序仍然被强制关闭。

这是日志

if(vid.equals("")) {
inFileName = img.substring(img.lastIndexOf('/') + 1);

File sdcard = Environment.getExternalStorageDirectory();
File filex = new File(sdcard, inDir + "/" + "IMAGE_" + inFileName);
if(filex.exists()) {
    if (inDialog.isShowing())
        inDialog.dismiss();

    Uri uri = FileProvider.getUriForFile(inContext, inContext.getApplicationContext().getPackageName() + ".provider", new File("file://" + filex.toString()));
    Intent i = new Intent(Intent.ACTION_VIEW);
    i.setDataAndType(uri, "image/*");
    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    inContext.startActivity(i);
} else {
    inTmp = Uri.parse(img);
    Image_DownloadId = DownloadData(inTmp, "IMAGE_" + inFileName);
}

此行还有其他错误
