VideoView "Can't play this video"

Question

我正在尝试在 videoView 中播放视频，但无法播放。
这是我的 java 代码：

package com.ggblbl.videoView;

import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.VideoView;

public class RandomVideoBlueActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_random_video_blue);

        VideoView videoBlue = (VideoView) findViewById(R.id.videoViewBlue);
        String videoPathBlue = "android.resource://"+getPackageName()+"/"+R.raw.blue_video;
        Uri videoUriBlue = Uri.parse(videoPathBlue);
        videoBlue.setVideoURI(videoUriBlue);
        videoBlue.start();
    }
}

我的视频名称是video_blue.mp4.

这是我的 activity XML:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.ggblbl.videoView.RandomVideoBlueActivity">

    <VideoView
        android:id="@+id/videoViewBlue"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_marginBottom="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginRight="8dp"
        android:layout_marginTop="8dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>

我已经在我的 LG L70 (D320n) 上测试过了。
不过，在我的摩托罗拉 Moto G1 上它确实有效。

我做了一些测试，视频的分辨率似乎对我这个可怜的老家伙来说太高了 phone... 我想我必须找到一种方法来缩小每个 phone.
