Cannot resolve symbol '#xml/device_admin'

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

Splashscreen and Intents

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 .
Manifest code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

} else{
Toast.makeText(this, "Error occured, URI is invalid", Toast.LENGTH_LONG).show();
}
}
}

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" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".AlertExampleActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity android:name=".SplashScreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
<data android:mimeType="text/*" />
</intent-filter>
</activity>
</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.

Push notify doesn't arrive

I build an android app composed by a web view, in parse.com i've got my device registered but when i send a push notification in "pushes sent" there is 0 pushes.
this is my Mainactivity:
import com.party.bparty.MainActivity;
import com.parse.Parse;
import com.parse.ParseInstallation;
import com.parse.ParsePush;
import com.parse.ParseQuery;
import com.parse.PushService;
public class MainActivity extends ActionBarActivity {
private WebView mWebView;
private String url = "http://www.bestparty.altervista.org";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//attivo parse per le notifiche
Parse.initialize(this,"zJxpd9798Ns6A9rzUDpe78ElRY0I99ES3LD6nDQV","kmAmA1iTbC32BTE9ERtzNOoHXbJchhIn6tyPXKMi");
PushService.setDefaultPushCallback(this, MainActivity.class);
ParseInstallation.getCurrentInstallation().saveInBackground();
//...
//...initializing and loading the contentview and the webview
}
//options menu omitted
}
this is my MycustomReceiver
public class MyCustomReceiver extends BroadcastReceiver {
private static final String TAG = "MyCustomReceiver";
#Override
public void onReceive(Context context, Intent intent) {
try {
if (intent == null)
Log.d(TAG, "Receiver intent null");
else {
String action = intent.getAction();
Log.d(TAG, "got action " + action );
if (action.equals("com.party.bparty.UPDATE_STATUS")) {
String channel = intent.getExtras().getString("com.parse.Channel");
JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
Log.d(TAG, "got action " + action + " on channel " + channel + " with:");
Iterator itr = json.keys();
while (itr.hasNext()) {
String key = (String) itr.next();
if (key.equals("customdata")) {
Intent pupInt = new Intent(context, ShowPopUp.class);
pupInt.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
context.getApplicationContext().startActivity(pupInt);
}
Log.d(TAG, "..." + key + " => " + json.getString(key));
}
}
}
}
catch (JSONException e) {
Log.d(TAG, "JSONException: " + e.getMessage());
}
}
}
and this is my ShowPopup
public class ShowPopUp extends Activity implements OnClickListener {
Button ok, cancel;
boolean click = true;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTitle("Cupon");
setContentView(R.layout.popupdialog);
ok = (Button)findViewById(R.id.popOkB);
ok.setOnClickListener(this);
cancel = (Button)findViewById(R.id.popCancelB);
cancel.setOnClickListener(this);
}
#Override
public void onClick(View arg0) {
finish();
}
}
And this is my manifest

Where's my error?
I do it, but it doesn't work anyway
" if (action.equals("com.party.bparty.UPDATE_STATUS")) {
Pick one, either com.party.bparty.UPDATE_STATUS or com.iakremera.pushnotificationdemo.UPDATE_STATUS"
but Now i have 1 "PUSH SENT" in push sent, but my device doesn't show any push

Your receiver has the wrong filter. Your receiver is declared as this:
<receiver android:name="com.party.bparty.MyCustomReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.USER_PRESENT" />
<action android:name="com.iakremera.pushnotificationdemo.UPDATE_STATUS" />
</intent-filter>
</receiver>
but you are checking for a different intent action in the code:
if (action.equals("com.party.bparty.UPDATE_STATUS")) {
Pick one, either com.party.bparty.UPDATE_STATUS or com.iakremera.pushnotificationdemo.UPDATE_STATUS and also make sure that Parse knows which one it is when you perform the push itself.

I got message id from gcm. but I'm not receiving on emulator

this is the sender code which is used to send message to gcm.
//sJSONObject obj = new JSONObject();
Sender sender = new Sender(GOOGLE_SERVER_KEY);
Message message = new Message.Builder().timeToLive(120)
.delayWhileIdle(true).addData(MESSAGE_KEY, userMessage).build();
System.out.println("regId: " + regId);
Object result = sender.send(message, regId, 5);
if (StringUtils.isEmpty(((Result) result).getErrorCodeName())) {
System.out.println("success");
System.out.println(result.toString());
}
else{
System.out.println(((Result) result).getErrorCodeName());
System.out.println(result.toString());

Still i'm not getting push notification on emulator. i have tried it on device as well. same problem occurs there as well.

I had a similar problem. I solved it using the classes in This GitHub example specifically noting the following:
Three 'services' and one 'receiver' together with all the permissions added in the github example.
AndroidManifest.xml
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.VIBRATE" />
<permission
android:name="<yourpackagename>.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="<yourpackagename>.permission.C2D_MESSAGE" />
<service

android:exported="false" >
</service>
<service
android:name=".utility.MyGcmListenerService"
android:exported="false" >

actionandroid:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter</service>
<service
android:name=".utility.MyInstanceIdListenerService"
android:exported="false">
<intent-filter>
<action android:name="com.google.android.gms.iid.InstanceID"/>
</intent-filter>
</service>
<receiver
android:name="com.google.android.gms.gcm.GcmReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION"/>
<category android:name="<com.example.yourpackagename>" />
</intent-filter>
</receiver>
The Receiver is implemented in the
ActivityMain.java:
mRegistrationBroadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context);
boolean sentToken = sharedPreferences.getBoolean(SENT_TOKEN_TO_SERVER, false);
if (sentToken) {
} else {
}
}
};
#Override
protected void onResume() {
super.onResume();
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter("registrationComplete"));
}
#Override
protected void onPause() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(mRegistrationBroadcastReceiver);
super.onPause();
}
You can basically use the other files just like they are:
MyGcmListenerService.java - The one where you can customize your notification icon and text.
MyInstanceIDListenerService.java
QuickstartPreferences.java
RegistrationIntentService.java

Android - ClassNotFoundException (TwitterAPI)

Okay so I've been messing around with the Twitter API, and all of a sudden I've started to get the ClassNotFoundException error code when I try and enter the Activity which has my login box to sign into Twitter.

This is my LoginActivity.java.
package josh.com.socialme;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import com.codepath.oauth.OAuthLoginActivity;
public class LoginActivity extends OAuthLoginActivity<TwitterClient> {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
}
// Inflate the menu; this adds items to the action bar if it is present.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.login, menu);
return true;
}
// OAuth authenticated successfully, launch primary authenticated activity
// i.e Display application "homepage"
#Override
public void onLoginSuccess() {
// Intent i = new Intent(this, PhotosActivity.class);
// startActivity(i);
}
// OAuth authentication flow failed, handle the error
// i.e Display an error dialog or toast
#Override
public void onLoginFailure(Exception e) {
e.printStackTrace();
}
// Click handler method for the button used to start OAuth flow
// Uses the client to initiate OAuth authorization
// This should be tied to a button used to login
public void loginToRest(View view) {
getClient().connect();
}
}
This is my AndroidManifest.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:label="#string/title_activity_feed" >
</activity>
<activity
android:name=".LoginActivity"
android:label="#string/app_name" >
</activity>
</application>
</manifest>
And this is my method I use to get to the activity.
private void selectItem(int position) {
// Handle Navigation Options
Intent intent;
switch (position) {
case 1:
intent = new Intent(getActivity(), Feed.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
getActivity().startActivity(intent);
break;
case 2:
intent = new Intent(getActivity(), LoginActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
getActivity().startActivity(intent);
break;
}
}
I would greatly appreciate it if someone could point me towards the right direction.
Kind regards,
Josh
