I have problem create a basic applicationn for google glass based on this tutorial. I have 2 classes. I followed exactly the same as the tutorial, but I couldn't find it in google glass. I tried from "Ok Glass", but I also couldnt find it.
I have created 2 classes, the first is HelloWorldActivity.java. This class is a Activity class. Here is the HelloWorldActivity.java
public class HelloWorldActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Card myCard = new Card(this);
myCard.setText("Hello, World!");
myCard.setFootnote("First Glassware for Glass");
View cardView = myCard.getView();
// Display the card we just created
setContentView(cardView);
}
}
The second is HelloGlass.java This class is a Service class that will recognize the voice command.
public class HelloGlass extends Service {
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
public int onStartCommand(Intent intent, int flags, int startId) {
Intent i = new Intent(this, HelloWorldActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
return START_STICKY;
}
}
I have created the necessary xml files including the voice_trigger_start.xml. Here is the andorid manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.app.helloglass"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".HelloWorldActivity"
android:label="#string/app_name"
android:enabled="true" >
</activity>
<service
android:name="com.app.helloglass.HelloGlass"
android:enabled="true"
android:exported="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.google.android.glass.action.VOICE_TRIGGER" />
</intent-filter>
<!-- Voice command found in res/xml/voice_trigger_start -->
<meta-data
android:name="com.google.android.glass.VoiceTrigger"
android:resource="#xml/voice_trigger_start" />
</service>
</application>
</manifest>
Anybody know what I have missed? I tried to run it but I couldn't find it.
Edit:
After adding the permission, the voice command works fine but the app crashes because the package name in the manifest is wrong.
See the whole update project on my GitHub.
The tutorial uses a custom voice command. You need this permission in the manifest:
<uses-permission android:name="com.google.android.glass.permission.DEVELOPMENT" />
Please see Why is my voice command missing from the ok glass menu in XE16? and also https://developers.google.com/glass/develop/gdk/voice
Could you try this manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.app.helloglass"
android:versionCode="1"
android:versionName="1.0" >

android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".HelloWorldActivity"
android:label="#string/app_name"
android:enabled="true" >
</activity>
<service
android:name="com.app.helloglass.HelloGlass"
android:enabled="true"
android:exported="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.google.android.glass.action.VOICE_TRIGGER" />
</intent-filter>
<!-- Voice command found in res/xml/voice_trigger_start -->
<meta-data

I want to have a secondary activity which will be a map activity that can be opened by a button click on the main menu of an app. So I am using the built in map activity in android studio and when I try and launch that alone the map works. But when I try to add a main home page with button and then use that button to launch the map it doesn't work and my app closes. Does anyone know the correct way to launch a normal map from a button. I have all the implementations in the gradle files correct. I will include my manifest and main activity below.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_fragment1,container,false);
bt = v.findViewById(R.id.launchmap);
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(), MapsActivity.class);
startActivity(intent);
}
});
return v;
}
}

#Android_map
I am trying to make a Unity app go into kiosk mode by using COSU (Corporate Owned Single Use) functionality.
My plan was to first get things working using just Android, so I followed the tutorial offered by Google Code Labs
After I got this working, my plan was to then figure out how to integrate this into my Unity project. I followed
this youtube video that showed how to make a plugin that can be called from Unity.
When I build my project, I try to execute the following command
adb shell dpm set-device-owner com.modalvr.unityplugin/.DeviceAdminReceiver
However, I keep getting the following error
Error: Unknown admin: ComponentInfo{com.modalvr.unityplugin/com.modalvr.unityplugin.DeviceAdminReceiver}
I wonder if Unity is not merging the AndroidManifest.xml files together correctly. Here is my AndroidManifest.xml file from plugin.
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.modalvr.unityplugin">
<application android:allowBackup="true" android:label="#string/app_name" android:supportsRtl="true">
<receiver
android:name="com.modalvr.unityplugin.DeviceAdminReceiver"
android:description="#string/app_name"
android:label="#string/app_name"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<meta-data
android:name="android.app.device_admin"
android:resource="#xml/device_admin_receiver" />
<intent-filter>
<action android:name="android.intent.action.DEVICE_ADMIN_ENABLED"/>
<action android:name="android.intent.action.PROFILE_PROVISIONING_COMPLETE"/>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
</application>
</manifest>
I copied it and the classes.jar file into Unity's Assets/Plugins/Android/libs folder
I am able to successfully call functions in my plugin, so the plugin appears to be set up correctly.
For reference, this is my C# code that calls into the plugin
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class LockManager : MonoBehaviour {
#if UNITY_ANDROID
private AndroidJavaObject playerActivityContext = null;
#endif
public void SaveContext() {
#if UNITY_ANDROID
// First, obtain the current activity context
using (var actClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer")) {
playerActivityContext = actClass.GetStatic<AndroidJavaObject>("currentActivity");
}
var plugin = new AndroidJavaClass("com.modalvr.unityplugin.PluginClass");
plugin.CallStatic<bool>("setContext", playerActivityContext);
#endif
}
public void LockButtonClicked() {
#if UNITY_ANDROID
SaveContext();
var plugin = new AndroidJavaClass("com.modalvr.unityplugin.PluginClass");
bool retVal = plugin.CallStatic<bool>("lock", 7);
#endif
}
public void UnlockButtonClicked() {
#if UNITY_ANDROID
SaveContext();
var plugin = new AndroidJavaClass("com.modalvr.unityplugin.PluginClass");
bool retVal = plugin.CallStatic<bool>("unlock", 7);
#endif
}
}
And this is the java class that defines those functions.
package com.modalvr.unityplugin;
import android.app.Activity;
import android.content.Context;
import android.util.Log;
public class PluginClass {
private static Context context;
public static boolean setContext(Context ctx) {
context = ctx;
return true;
}
public static boolean lock(int number) {
Log.d("SOME TAG", "onReceive Lock");
Activity activity = (Activity) context;
activity.startLockTask();
return true;
}
public static boolean unlock(int number) {
Log.d("SOME TAG", "onReceive Unlock");
Activity activity = (Activity) context;
activity.stopLockTask();
return true;
}
}
It looks like Unity generates 2 XML files that it puts in Temp/StagingArea
AndroidManfist.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.ModalVR.KioskPluginTest" xmlns:tools="http://schemas.android.com/tools" android:versionName="1.0" android:versionCode="1" android:installLocation="preferExternal">

In neither of these files do I see the contents of my Android plugin AndroidManifest.xml I guess that is the issue. Do I need to do something to make the manifest files merge?
And for completeness, here is
DeviceAdminReceiver.java
package com.modalvr.unityplugin;
import android.content.ComponentName;
import android.content.Context;
/**
* Handles events related to the managed profile.
*/
public class DeviceAdminReceiver extends android.app.admin.DeviceAdminReceiver {
private static final String TAG = "DeviceAdminReceiver";
/**
* #param context The context of the application.
* #return The component name of this component in the given context.
*/
public static ComponentName getComponentName(Context context) {
return new ComponentName(context.getApplicationContext(), DeviceAdminReceiver.class);
}
}
Thanks in advance for any help.

Do I need to do something to make the manifest files merge?
Yes.
The manifest in Unity will automatically merge only if you compile the Java plugin as .aar package. If you build it as .jar file then you have to manually put the Manifest in the right folder in Unity so that Unity can merge it into your program during build.
You are currently building as .jar library so below is where to place the Manifest:
Put the AndroidManifest.xml file in your <ProjectName>Assets\Plugins\Android folder. Make sure to spell AndroidManifest and the folder names of where to put it correctly. That's it.
I have created a sample app called NoteApp, that can save data to Parse. I have created the app in Parse as per the image below, and have created the app..which is still in progress.
I have created the object"testObject", I have matched the ID, and imported data(Ctrl+Shift+O)but when I try to run the app, and check the Parse dashboard, I can't see the object being created. I have tried this so many times, I don't know where the problem is. I just can't link my android app in eclipse with the Parse.com. the app can't create the object, hence I can't save data.
Here is the Application code, and the manifest file, and the image of the Parse.com Dashboard.
NoteApplication.java
package com.echessa.noteapp;![enter image description here][1]
import android.app.Application;
import com.parse.Parse;
import com.parse.ParseObject;
public class NoteApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
Parse.initialize(NoteApplication.this, "XXXXXXXXXXXXXXXX","XXXXXXXXXXXXXXXXXX");
ParseObject testObject = new ParseObject("TestObject");
testObject.put("foo", "bar");
testObject.saveInBackground();
}
}

Here's the error, referring to where I call startActivity(Intent):
`05-17 01:40:37.918: E/AndroidRuntime(12997):android.content.ActivityNotFoundException:
Unable to find explicit activity class {/com.rhombi.Menu}; have you declared
this activity in your AndroidManifest.xml?
Here's how I use startActivity(Intent) in com.rhombi.Intro:
startActivity(iMenu);
Here's how I declare it earlier, in the same class:
public Intent iMenu = new Intent(this, Menu.class);
Here's how I declare it all in my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:screenOrientation="portrait" >
</activity>
</application>
</manifest>
I've searched through a TON of other questions about this and I can't seem to figure out what the issue is. The one thing that makes my issue unique is that little forward slash when it tells me that it's unable to find the explicit activity class ("{/com.rhombi.Menu}"). That never showed up in my searches, but I appear to be doing everything right.
There was something wrong with the this you passed as a Context to the Intent constructor, as evidenced by the empty package name in ComponentInfo {/com.rhombi.Menu} - there's just the class name.
try changing
android:name=".Menu" to android:name="{package name}.Menu"
I am trying to use google map for my android application but all i get is grey grids and in logcat it shows error like :
