I am trying to implement screen pinning on an Android 5.1 Device. I came across This Answer, and in trying to add a intent-filter to my Manifest, I get this error: Cannot resolve symbol '#xml/device_admin'.
I assume this is because xml/device_admin doesn't exist, so if this is the case, where do I create it?

I assume this is because xml/device_admin doesn't exist, so if this is
the case, where do I create it?
Create Folder in hierarchy application/src/main/res/xml keep the file device_admin.xml in this XML folder
Structure of device_admin.xml file is
<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
<uses-policies>
<limit-password />
<watch-login />
<reset-password />
<force-lock />
<wipe-data />
<expire-password />

Your object is null during onDestroy, maybe wrap it around a check like
#Override
protected void onDestroy() {
super.onDestroy();
if (countDownTimer!=null) {
countDownTimer.cancel();
}
}
I'm developing this android application, that receives data from the gallery (in my case an image) and displays it. What i also had to do is to create a SplashScreen for my app. But when i did my intent became null .

You did not add any extra data to your intent. So it would be null normally. Just add necessary data to Intent (i) on SplashScreen.java. Ex -
i.setAction("action");
i.setType("type");
i.putExtra("key", "value");
I am not sure if this gonna solve your problem but you can try.
Instead of :
Intent i = new Intent(SplashScreen.this, AlertExampleActivity.class);
startActivity(i);
// close this activity
finish();
Try this:
startActivity(new Intent(SplashScreen.this, AlertExampleActivity.class));
finish();
I've changed the manifest file since i want the splashscreen to appear even when it's externally called .
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

<data android:mimeType="text/*" />
</intent-filter>

</application>
And changed the SplashscreenActivity :
public class SplashScreen extends Activity {
private static final int DISPLAY_DURATION = 1000;
#Override
protected final void onCreate(final Bundle savedInstState) {
super.onCreate(savedInstState);
setContentView(R.layout.activity_splashscreen);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent i = new Intent(SplashScreen.this, AlertExampleActivity.class);
i.setAction(Intent.ACTION_SEND);
i.setType("*/*");
String[] mimetypes = {"image/*", "video/*"};
i.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
startActivity(i);
// close this activity
finish();
}
}, DISPLAY_DURATION);
}
}
I haven't changed anything in the MainActivity , but now i no longer receive the image ... I'm new to Android so i would really appreciate the explanation.

Did you declare your activity in the manifest?
If you did, this question was asked before, try the following:
Android Sound not playing in splash screen
How to play audio in splash screen in android
You can try this
MediaPlayer player = new MediaPlayer();
player.setDataSource("/sdcard/audiotrack.mp3");
player.prepare();
player.start();
I'm trying to play an video on my android app, but when I click on the activity through my menu list, the app stays on the list and doesn't play the video.
The code is below
my menu
package com.example.taekwondobuddy.util;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class Kicks extends ListActivity {
String classes[] = {"FrontKick","RoundhouseKick","AxeKick"} ;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(Kicks.this, android.R.layout.simple_list_item_1, classes));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
String cheese = classes[position];
try{
Class ourclass = Class.forName("com.example.taekwondobuddy.util" + cheese);
Intent ourIntent = new Intent(Kicks.this, ourclass);
startActivity(ourIntent);
} catch(ClassNotFoundException e){
e.printStackTrace();
}
}
}
the video I'm trying to play
package com.example.taekwondobuddy.util;
import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;
public class RoundhouseKick extends Activity {
private VideoView mVideoView;
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.roundhousekick);
mVideoView = (VideoView) findViewById(R.id.roundhousekick);
mVideoView.setVideoURI(Uri.parse("android.resource://" + getPackageName() +"/"+R.raw.roundhousekick));
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
}
}
the xml layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I think it something wrong with the manifest but I can't really see what's wrong, any ideas? Plus the video are in mp4 so they're are in the right format for android
I think, you just missed one little thing: a dot (.)
See at your code here:
Class ourclass = Class.forName("com.example.taekwondobuddy.util" + cheese);
don't you think it should be like this:
Class ourclass = Class.forName("com.example.taekwondobuddy.util." + cheese);
Try to use:
mVideoView.start();
