Hi everybody,
First excuse my bad English.
I try to integrate unity in a native android application that use fragments. Indeed, I would like to add my unity's view in a fragment. I use Unity3d Version 4.3.4f1 (free) and Vuforia 2.8.
So I export my project into a unity eclipse project. Then I copy the lib folder unity project in the lib folder of my android project. I do the same for the assets folder. I then changed my main activity like this:package com.orkeis.prototype; import java.util.ArrayList; import android.app.Activity; import android.app.Fragment; import android.app.FragmentManager; import android.content.res.Configuration; import android.content.res.TypedArray; import android.os.Bundle; import android.support.v4.app.ActionBarDrawerToggle; import android.support.v4.widget.DrawerLayout; import android.util.Log; import android.view.KeyEvent; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.AdapterView; import android.widget.ListView; import com.orkeis.prototype.adapter.NavDrawerListAdapter; import com.orkeis.prototype.model.NavDrawerItem; import com.unity3d.player.UnityPlayer; public class MainActivity extends Activity { private DrawerLayout mDrawerLayout; private ListView mDrawerList; private ActionBarDrawerToggle mDrawerToggle; // nav drawer title private CharSequence mDrawerTitle; // used to store app title private CharSequence mTitle; // slide menu items private String[] navMenuTitles; private TypedArray navMenuIcons; private ArrayList<NavDrawerItem> navDrawerItems; private NavDrawerListAdapter adapter; protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTitle = mDrawerTitle = getTitle(); mUnityPlayer = new UnityPlayer(this); int glesMode = mUnityPlayer.getSettings().getInt("gles_mode", 1); boolean trueColor8888 = false; mUnityPlayer.init(glesMode, trueColor8888); // load slide menu items navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items); // nav drawer icons from resources navMenuIcons = getResources() .obtainTypedArray(R.array.nav_drawer_icons); mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mDrawerList = (ListView) findViewById(R.id.list_slidermenu); navDrawerItems = new ArrayList<NavDrawerItem>(); // adding nav drawer items to array // Home navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1))); // Find People navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1))); // Photos navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1))); // Communities, Will add a counter here navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1), true, "22")); // Pages navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1))); // What's hot, We will add a counter here navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1), true, "50+")); // Recycle the typed array navMenuIcons.recycle(); mDrawerList.setOnItemClickListener(new SlideMenuClickListener()); // setting the nav drawer list adapter adapter = new NavDrawerListAdapter(getApplicationContext(), navDrawerItems); mDrawerList.setAdapter(adapter); // enabling action bar app icon and behaving it as toggle button getActionBar().setDisplayHomeAsUpEnabled(true); getActionBar().setHomeButtonEnabled(true); mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, //nav menu toggle icon R.string.app_name, // nav drawer open - description for accessibility R.string.app_name // nav drawer close - description for accessibility ) { public void onDrawerClosed(View view) { getActionBar().setTitle(mTitle); // calling onPrepareOptionsMenu() to show action bar icons invalidateOptionsMenu(); } public void onDrawerOpened(View drawerView) { getActionBar().setTitle(mDrawerTitle); // calling onPrepareOptionsMenu() to hide action bar icons invalidateOptionsMenu(); } }; mDrawerLayout.setDrawerListener(mDrawerToggle); if (savedInstanceState == null) { // on first time display view for first nav item displayView(0); } } public UnityPlayer getmUnityPlayer() { return mUnityPlayer; } public void setmUnityPlayer(UnityPlayer mUnityPlayer) { this.mUnityPlayer = mUnityPlayer; } /** * Slide menu item click listener * */ private class SlideMenuClickListener implements ListView.OnItemClickListener { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // display view for selected nav drawer item displayView(position); } } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // toggle nav drawer on selecting action bar app icon/title if (mDrawerToggle.onOptionsItemSelected(item)) { return true; } // Handle action bar actions click switch (item.getItemId()) { case R.id.action_settings: return true; default: return super.onOptionsItemSelected(item); } } /* * * Called when invalidateOptionsMenu() is triggered */ @Override public boolean onPrepareOptionsMenu(Menu menu) { // if nav drawer is opened, hide the action items boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList); menu.findItem(R.id.action_settings).setVisible(!drawerOpen); return super.onPrepareOptionsMenu(menu); } /** * Diplaying fragment view for selected nav drawer list item * */ private void displayView(int position) { // update the main content by replacing fragments Fragment fragment = null; switch (position) { case 0: fragment = new HomeFragment(mUnityPlayer); break; case 1: fragment = new FindPeopleFragment(); break; case 2: fragment = new PhotosFragment(); break; case 3: fragment = new CommunityFragment(); break; case 4: fragment = new PagesFragment(); break; case 5: fragment = new WhatsHotFragment(); break; default: break; } if (fragment != null) { FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction() .replace(R.id.frame_container, fragment).commit(); // update selected item and title, then close the drawer mDrawerList.setItemChecked(position, true); mDrawerList.setSelection(position); setTitle(navMenuTitles[position]); mDrawerLayout.closeDrawer(mDrawerList); } else { // error in creating fragment Log.e("MainActivity", "Error in creating fragment"); } } @Override public void setTitle(CharSequence title) { mTitle = title; getActionBar().setTitle(mTitle); } /** * When using the ActionBarDrawerToggle, you must call it during * onPostCreate() and onConfigurationChanged()... */ @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); // Sync the toggle state after onRestoreInstanceState has occurred. mDrawerToggle.syncState(); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); // Pass any configuration change to the drawer toggls mDrawerToggle.onConfigurationChanged(newConfig); mUnityPlayer.configurationChanged(newConfig); } public void onDestroy () { mUnityPlayer.quit(); super.onDestroy(); } // onPause()/onResume() must be sent to UnityPlayer to enable pause and resource recreation on resume. public void onPause() { super.onPause(); mUnityPlayer.pause(); } public void onResume() { super.onResume(); mUnityPlayer.resume(); } public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); mUnityPlayer.windowFocusChanged(hasFocus); } public boolean dispatchKeyEvent(KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_MULTIPLE) return mUnityPlayer.onKeyMultiple(event.getKeyCode(), event.getRepeatCount(), event); return super.dispatchKeyEvent(event); } }
My Homefragment in wich there is the Unity view :
package com.orkeis.prototype; import android.annotation.SuppressLint; import android.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import com.unity3d.player.UnityPlayer; //import android.os.Bundle; //import android.view.View; @SuppressLint("ValidFragment") public class HomeFragment extends Fragment { UnityPlayer munityPlayer; public HomeFragment(){}; public HomeFragment(UnityPlayer munityPlayer){ this.munityPlayer = munityPlayer; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // View rootView = inflater.inflate(R.layout.fragment_home, container, false); View playerView = this.munityPlayer.getView(); return playerView; } }
and my manifest like this:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.orkeis.prototype" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="11" android:targetSdkVersion="19" /> <!-- Ajout --> <uses-feature android:name="android.hardware.camera" /> <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <!-- Fin ajout --> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.orkeis.prototype.MainActivity" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen" android:label="@string/app_name" android:screenOrientation="sensor" > <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="true" /> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.unity3d.player.VideoPlayer" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen" android:label="@string/app_name" android:screenOrientation="sensor" > </activity> </application> <uses-feature android:glEsVersion="0x00020000" /> <uses-feature android:name="android.hardware.camera.autofocus" android:required="true" /> <uses-feature android:name="android.hardware.camera.front" android:required="true" /> <uses-feature android:name="android.hardware.touchscreen" /> <uses-feature android:name="android.hardware.touchscreen.multitouch" android:required="true" /> <uses-feature android:name="android.hardware.touchscreen.multitouch.distinct" android:required="true" /> <uses-feature android:name="android.hardware.camera" android:required="true" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> </manifest>
However, when I run my application, I see the guiText of my Unity app but my camera does not start. Here is the log:

Unity to Android's Fragment Unable to find QCARWrapper
See this article:

Unity to Android's Fragment Unable to find QCARWrapper
Thanks for your response but I already read this article and many others before post my question. They didn't help me.
Do you know what triggers the error Unable to find QCARWrapper exactly and the things I must to change in my code ?
