With the update of the google play console I get the error reports.

Apparently only affects the version of Android 7 (Android N)

Searching for more information on FileUriExposedException

The exception jumps when I open a file .kml with an external application to my app, that is, through an intent.

private void openTrackKML() {
    try {
        String fileName = myItem.getTrackURI();
                /*int pos = fileName.lastIndexOf(".");
                if (pos > 0) {
                    fileName = fileName.substring(0, pos);
                }*/

        //int idTrackResource = this.getResources().getIdentifier("raw/" +fileName,"id",this.getPackageName());

        ByteArrayOutputStream byteArrayOutputStream = FileDirUtils.readFileFromAssets(this, fileName);
        FileDirUtils.saveExternalFile(byteArrayOutputStream, "temp_track.kml");

        Log.d(TAG, "id Track Rresource: " + String.valueOf(fileName));

        File file = new File(Environment.getExternalStorageDirectory(), "temp_track.kml");
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setDataAndType(Uri.fromFile(file), "application/vnd.google-earth.kml+xml");
        startActivity(intent);

                /*//Open by url
                Uri uri = Uri.parse(myItem.getTrackURI());
                Log.d(TAG, "action_gotrack click()" + uri.toString());
                if (URLUtil.isValidUrl(uri.toString())) {
                    //startActivity( new Intent(Intent.ACTION_VIEW, uri));
                }*/
    } catch (ActivityNotFoundException e) {
        Snackbar.make(getWindow().getDecorView(), getString(R.string.detailed_warning_install_kml_viewer), Snackbar.LENGTH_LONG)
                .setAction("Action", null).show();
    }

}

Write permissions, I also ask for them in runtime

<uses-permission
    android:name="android.permission.INTERNET"
    android:required="false" />
<uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    android:required="false" />
<uses-permission
    android:name="android.permission.READ_EXTERNAL_STORAGE"
    android:required="false" />

Testing in the emulator, because I do not have Android N device returns me

This error FileUriExposedException is generated as you have already explained in Android N :

Now you have to make a change when you get the Uri of the file by:

imageUri = Uri.parse(filepath);

example:

     if (Build.VERSION.SDK_INT >=  Build.VERSION_CODES.N) {
              imageUri = Uri.parse(filepath);
        } else{
               imageUri = Uri.fromFile(new File(filepath));
        }

In your code it would be:

if (Build.VERSION.SDK_INT >=  Build.VERSION_CODES.N) {                
    intent.setDataAndType(Uri.parse(Environment.getExternalStorageDirectory() + "temp_track.kml"), "application/vnd.google-earth.kml+xml");        
} else{
    intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "temp_track.kml"), "application/vnd.google-earth.kml+xml");
}

Another solution is to change the targetSdkVersion to a version smaller than 24 (Android N)

It is similar to the problem in this question:
