我似乎无法在我的设备(Nexus 7)上播放视频。我决定重新开始一个新项目来解决这个问题。
视频存储在 res/raw 中。
就是这个视频: http: //www.howtodance.org/media/Lesson_2__9_lindy_demo_2__shoulder_pop_with_scoop_around.mp4
我已经尝试了许多在 stackoverflow 上建议的方法。这是我尝试过的最新方法:
<!-- main.xml -->
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="@+id/button"
android:layout_gravity="center"
android:onClick="onButtonClick"
/>
</LinearLayout>
//MyActivity.java
package com.example.VideoTests;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import java.io.File;
public class MyActivity extends Activity {
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void onButtonClick(View v){
Log.d("working", "PlayVideo();");
// both of these urls don't seem to work
//String uriString = "android.resource://com.example.VideoTests/raw/lesson_2__9_lindy_demo_2__shoulder_pop_with_scoop_around.mp4";
String uriString = "android.resource://" + getPackageName() + "/" + R.raw.lesson_2__9_lindy_demo_2__shoulder_pop_with_scoop_around;
//Uri video = Uri.parse(uriString);
File file = new File(uriString); // video player selection dialog doesn't seem to load at all unless I send it through a file first.
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "video/mp4");
startActivity(intent); // this is where it seems to crash
}
}
添加文件对象后,对话框终于出现了,但随后我收到一条消息“无法播放此视频”和以下错误:
ERROR/(128): Failed to open file '/android.resource:/com.example.VideoTests/2130968576'. (No such file or directory)
如果我使用其他 uriString,它仍然给我这个错误:
ERROR/(128): Failed to open file '/android.resource:/com.example.VideoTests/raw/lesson_2__9_lindy_demo_2__shoulder_pop_with_scoop_around.mp4'. (No such file or directory)
我也尝试将视频文件名更改为像“asdf.mp4”这样的短名称,但也会出现同样的错误
提前感谢大家的帮助。
