Android calls system camera to record and save

1, add the following code in the Androidmanifest.xml

<?xml version= "1.0" encoding= "Utf-8"? ><manifest xmlns:android= "Http://schemas.android.com/apk/res/android"

<uses-permission android:name= "Android.permission.INTERNET"/>
<uses-permission android:name= "Android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name= "Android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name= "Android.permission.MOUNT_UNMOUNT_FILESYSTEMS"
    Tools:ignore= "Protectedpermissions"/>

<application

<provider
    Android:authorities= "${applicationid}.provider"
    Android:name= "Android.support.v4.content.FileProvider"
    Android:exported= "false"
    Android:granturipermissions= "true" >
    <meta-data android:name= "Android.support.FILE_PROVIDER_PATHS"
        Android:resource= "@xml/provider_paths" >
    </meta-data>
</provider>

</application></manifest>

2. Create a new XML folder in the Res directory and create a new provider_paths XML file

<?xml version= "1.0" encoding= "Utf-8"? ><paths xmlns:android= "Http://schemas.android.com/apk/res/android" >    <external-path name= "External_files" path= "." /></paths>

3. Open the camera in the main file

Intent intent=new Intent (mediastore.action_video_capture);
try {

    Fileuri=uri.fromfile (Createmediafile ()); If this is the case, it will be an error
    Fileuri= Fileprovider.geturiforfile (Cameravideoactivity.this,getapplicationcontext (). GetPackageName () + ". Provider ", Createmediafile ());//This is the correct wording

} catch (IOException e) {
    E.printstacktrace ();
}
Intent.putextra (Mediastore.extra_output,fileuri);
Intent.putextra (mediastore.extra_video_quality,1);

Startactivityforresult (intent,1);

4. How to create and save videos

Private File Createmediafile () throws IOException {
if (utils.checksdcardavaliable ()) {
if ((Environment.getexternalstoragestate (). Equals (environment.media_mounted))) {
Select your Own folder
String path = Environment.getexternalstoragedirectory (). GetPath () + "/myvideo/";
Constants.video_url is a constant that represents the folder where the video is stored
File Mediastoragedir = new file (path);
if (!mediastoragedir.exists ()) {
if (!mediastoragedir.mkdirs ()) {
LOG.E ("TAG", "Folder creation failed");
return null;
}
}

The file is named according to the current number of milliseconds
String TimeStamp = string.valueof (System.currenttimemillis ());
TimeStamp = timestamp.substring (7);
String imagefilename = "V" + timeStamp;
String suffix = ". mp4";
File MediaFile = new file (Mediastoragedir + file.separator + imagefilename + suffix);
return mediafile;
}
}
return null;
}
}

5. Overriding the Onactivityresult method

@Override
protected void Onactivityresult (int requestcode, int resultcode, Intent data) {
    if (requestcode==1)
    {
        if (RESULTCODE==RESULT_OK)
        {
            Toast.maketext (This, "Video saved to:\n" +
                    Data.getdata (), Toast.length_long). Show ();
            Vv_play.setvideouri (Fileuri);
            Vv_play.requestfocus ();
        }
    }
}
