Video files such as MP4 and 3GP loaded in Android cannot be played.

Let me go and finally solve this problem.

When loading a video file in the android simulator, it will prompt: the video cannot be played! Therefore, I found the error log under logcat, which has the following lines of error display:
Error/playerdriver (31): Command player_prepare completed with an error or info
Pvmferrresource

: Error/mediaplayer (19049): Error (1,-17)

: Error/mediaplayer (19049): Error (1,-17)

Yesterday, I repeatedly searched,CodeNo error. It will happen at half past one. I chose to temporarily give up and put it aside. I checked some information on the Internet and could not find a solution to the problem. Today, I opened it again and looked at some source code. I tried to add the following code in the main. xml configuration information in the layout Folder:

<Textview

Android: layout_width = "fill_parent"

Android: layout_height = "wrap_content"

Android: text = "@ string/hello"

/>

Yes, it is fixed. Due to limited capabilities, I can only make the following understandings and explanations. If you have any different or better insights, I hope to raise them. The following is my main. xml configuration file:

 

<Framelayout

Xmlns: Android = "http://schemas.android.com/apk/res/android"

Android: layout_width = "fill_parent"

Android: layout_height = "fill_parent">

<Textview

Android: layout_width = "fill_parent"

Android: layout_height = "wrap_content"

Android: text = "@ string/hello"

/>

<Videoview

Android: Id = "@ + ID/video"

Android: layout_height = "wrap_content"

Android: layout_width = "wrap_content"

Android: layout_gravity = "center"/>

</Framelayout>

Since I am using the framelayout layout, we may wish to use framelayout as a canvas, fixed from the upper left corner of the screen to fill in images and text. For example, myProgramTo display the video file, I first display the text file, then fill in my video file, overwrite the former, and display it to the client.
